1.3
For the appropriate use of this manual it is required knowledge of the use and
installation of generator groups.

WARNING !!!
All interventions must be carried out only by qualified personnel, because there are dangerous
voltages on the terminals of the device; prior to performing any operation on them, make sure
you have opened the circuit breakers and generator set switches, or that you have removed
their fuses.
Do not remove or modify any of the connections while the generator is operating.
Do not, for any reason, disconnect the terminals of the current transformers (CTs).
Incorrect interventions on the connections may cause disconnection of the users from the
mains or from the generator.

The device uses a large number of configurable parameters and it is

therefore impossible to describe all their possible combinations and
effects.
In this document there is not a detailed description of all programming parameters: to this
purpose see [1]. The document [1] must be considered integral part of this manual.

The devices are supplied with a generic "default" configuration; it is the

installer responsibility to adjust the operating parameters to the desired
specific application.
SICES srl makes considerable efforts for a continuous improvement and upgrading of its own
products; therefore, they are subject to modifications both in hardware and software, without
prior notice. Some of the features described in this manual may consequently differ from those
present in your device.

1.4

IMPORTANT Both SW3 switches must remain in OFF position.

The SW3 switches are reserved for the access to special features that are not part of the
normal operation of the device.

If the device is powered with one of the two switches in ON position, it will not turn on.
In order to restore the normal operation, you need to cut the power, turn the switches OFF and
power it again.

In case the device does not turn on when powered, the first thing you have to do is to check
the position of the switches.

1.5
Although most of the parameters and features can be accessed and configured by directly
operating on the device, some particular features or configurations, due to their nature,
can only be set or changed through the PC program SICES Board Programmer3
(hereinafter referred to as “BoardPrg3”) provided on the CD that comes with the device and
downloadable for free after registration on the SICES srl websites www.sices.eu and
www.sicesbrasil.com.br.

It greatly simplifies the configuration of the device and its use is strongly recommended. It also
allows you to save the current configuration of the device on a file and to reuse it on other
identical devices,

The program also allows the configuration, saving or loading of the characteristic curves of
non-standard analogue sensors with resistive or live output.

BoardPrg3 can be used on all SICES devices; the connection to the PC can be realized both
directly, via RS232 serial port, USB, or remotely via modem, RS485 serial port or Ethernet
network. To use the program refer to document Error. Reference source not found.

4.1
The device must be mounted permanently on an electrical panel or cabinet. The back of the
device must be accessed only through the use of keys or tools, and only by authorized
personnel to perform maintenance operations. The device must be mounted so as to make it
impossible to remove it without using tools.

The dimensions of the mounting slot are 218x159mm. The device is mounted with four hooks
with locking screws: once you have put the device in place, insert the hooks in the side slots
and tighten the screws. Be careful not to overtighten the screws to avoid damaging the
coupling slots on the casing of the device.

4.2
Due to high voltages associated to the measurement circuits of the controller, all the
conductive parts of the electrical panel must necessarily be connected to the protective
earth by means of permanent connections.

The installation of an overcurrent protection device is required for each phase of the mains
and generator voltage inputs. 1A fuses can be conveniently used.

The conductor cross-section of the protective earth of the electrical panel must be at least
equal to the section of the wires used for wiring the mains or generator voltage to the panel.
In addition, it must comply with the limit value of the overcurrent protection used.

For CAT.III applications, the maximum phase-to-neutral voltage allowed is 300Vac, while the
phase-to-phase voltage is 520Vac. Maximum voltage with respect to the protective earth is
300Vac.

The device can operate in CAT.III only if the supply minus terminal of the device and the
neutral terminal of the generator are connected to the protective earth.

5.1
The connection to the functional earth JC is mandatory, in order to guarantee the proper
operation of the device and the compliance with the EU Electromagnetic Compatibility
Directive.

The connection is functional and not protective; therefore the cross-section of the wire can be
smaller. Connect the other end of the wire to a metal screw of the electrical panel (which must
be grounded) next to the JC or to a grounding line, using, in any case, the shortest cable
possible.

5.2

The JD connector is the supply connector: connect an uninterruptible power supply (usually
the engine starter battery) to the 1-GND terminal (minus) and to the 2-+BATT terminal (plus).
The minus terminal 1-(GND) is the reference and the common return of the digital inputs, of
the outputs and of the current and voltage measurements. It must be connected to the
protective earth. Systems requiring isolation between battery minus and protective earth are
nonetheless usable, but they may generate operating problems and could require special
precautions, such as the use of insulating voltage transformers for the Mains and Generator
voltage measurements.

Although the device is protected by a built-in self-resetting fuse, the use of a fuse for the
protection of the supply positive line 2-+BATT is recommended.

The current delivered by the JE outputs flows through the positive input 2-+BATT,
therefore you need to pay attention to the dimensioning of the fuse.
The device automatically recognizes when it is powered if the battery nominal voltage of the
generator is 12 or 24V for managing the related logics and alarms. The recognition also takes
place every time you switch to mode OFF/RESET.

Note: connect the positive voltage only after the connections are all established and
the fuses opened.

ATS115-ATS115Plus Technical Manual 19

 5.3

ATS115 has 8 digital inputs, which can be activated by connecting them to GND. When left
floating, the input brings itself to +Vbatt. Avoid situations where intermediate or undefined
voltage levels can occur.
The same command signal of an input can be shared by several different devices (for
instance one signal that goes to two ATS115). In this case it is recommended to
separate the inputs with diodes, as shown in the figure below. This is to prevent the
wrong activation of the input when one of the devices is being turned off.

5.4
In addition to the 8 JN inputs, if not used as measurement inputs, you can also use the
JM analogue inputs as digital inputs (refer to par. 5.11) and, with different methods, the JL-
4 terminal too (Ai4 signal, refer to par. 05).

In addition, there are 16 “virtual” inputs available, which are not present on the
controller or on the expansion, but they are obtained as a result of the logical
combination of physical or virtual inputs, outputs, alarms or logical states by means of
proper programming via BoardPrg3. The virtual inputs can be configured as feature and
can be used in the same way as the physical inputs; refer to par. Error. Reference source
not found. [4].

By default, all the digital inputs on the ATS115 are considered “active” when the related
terminal is connected to the supply minus of the controller; they are considered “not active”
when the related terminal is not connected to anything. The logic state of the input can be
reversed with respect to the physical state by selecting the “Reversed polarity” box on
the input configuration page on BoardPrg3. The box only appears if the function selected
is different from DIF.0000 – “Unused”.

You can also reverse the logic state (still individually for each input), by operating directly on
the controller, using the parameters P.2000 (for the inputs 1...8 on the controller), P.2100 (for
the analogue inputs when used as digital).

Said parameters have a bit for each input:

• A bit set to zero means that the related input is “active” when it is connected to the
negative supply of the controller.

• A bit set to one means that the related input is considered “active” when it is not
connected to anything (it will turn in “not active” when it is connected to the negative
supply of the controller).

As default, all the bits are set to 0.

Each input (both physical and virtual) has three parameters associated:

• One parameter that configures its function (P.2001 for input 1).

• One parameter that configures any delay (P.2002 for input 1).

• One parameter that configures a text message to display (P.2003 for input 1).

See document [1] for the parameters list.

The inputs management, both ATS115 physical and virtual digital inputs, is identical.

The parameters which configure the delay and the message for an input are used by the
controller only for certain features of the inputs. The table below shows when they are used.

NOTE: in BoardPrg3 the boxes for the delay and for the message are always displayed,
even if they are not used by the controller.

The identification codes of the inputs functions starting with 3xxx concern operating states,
those that start with 4xxx trigger alarms (interlocks, deactivations, warnings).

the source A.
DIF.4204 Source B fault warning. Yes When this input is “active” a warning is issued (with a fixed
description depending on the language) to detect a problem on
the source B.

By default, the functions of the inputs on the controller are the following:

Terminal Input Parameter Default function

JN-1 Input 1 P.2001 DIF.4203 – Source A fault.

JN-2 Input 2 P.2004 DIF.4204 – Source B fault.
JN-3 Input 3 P.2007 DIF.2281 – Switch on source A.
JN-4 Input 4 P.2010 DIF.2282 – Switch on source B.
JN-5 Input 5 P.2013 DIF.2501 – Genset operation inhibition.
JN-6 Input 6 P.2016 DIF.2003 – Neutral position.
JN-7 Input 7 P.2019 DIF.3001 – ACB status.
JN-8 Input 8 P.2022 DIF.3002 – BCB status.

5.5
In addition to the 8 digital physical inputs, the controller also manages 16 virtual digital inputs.
They are managed by the controller just as if they were physical inputs (with no limitation), but
the status of the virtual inputs is not acquired from the hardware, but it is determined through
the software. In fact, every digital input can have an AND/OR logic associated, which
determines its status (see par. 5.10).

A practical example of use. Suppose you want to activate a warning if the mains voltage
exceeds the tolerance thresholds. Let’s use the virtual digital input #1 (as example).

• Using the BoardPrg3 software, we associate an AND/OR logic configured as AND to

the virtual digital input #1, with the following list of conditions:

▪ ST.064 (“Status of the ACB”)

▪ ST.017 (“Source A out of tolerance or absent”).

• Therefore, the virtual digital input will be active when the ACB is closed and the source
A is out of tolerance.

• Let’s set the DIF.4001 function (“Generic warning”) within the P.2151 parameter.

ATS115-ATS115Plus Technical Manual 23

 • Let’s set the desired delay (for example 0.5 s) within the P.2152 parameter.

• Let’s set the alarm message (for example “Source A voltage warning”) within the
P.2153 parameter.

5.6

The controller uses two 10A@250Vac dry contact relays to control the loads changeover. On
the JI connector there is a dry contact changeover for each of the two relays.

Terminal Outputs Type Parameter Default function

JI-1 (NO) BCB relay normally open contact.
Relay
JI-2 (NC) BCB P.3008 BCB relay normally closed contact.
10 A
JI-3 (COM) BCB relay common contact.
JI-4 (NO) ACB relay normally open contact.
Relay
JI-5 (NC) ACB P.3007 ACB relay normally closed contact.
10 A
JI-6 (COM) ACB relay common contact.

The ACB command is used to connect the loads to the source A. The BCB command is used
to connect the loads to the source B.

You should use the normally closed contact of the ACB (by configuring the source A
as Mains) and the normally opened contact of the BCB (by configuring the source A as
Genset): in this way, even if the controller is not powered, the loads remain connected
to the source A.

Two different systems can be used for the loads switching:

• SWITCH: with only one command, the loads are switched to the source A or B. Use
the Jl-01 and Jl-03 terminals to control the SWITCH: in this way, with the controller
unpowered, the loads are automatically changed over to the source A. The ACB
output (terminals 4…6 of the JI) is not used, therefore it can be associated to a
different function. Configure the P.0307 parameter with the time the SWITCH needs
for the changeover: in this way the controller avoids reversing the command before
the changeover is completed (this operation risks to wedge in the SWITCH). Reset
the P.0306 parameter, because the pause between the mains and the genset and
vice versa is ensured by the SWITCH.

• Two separate breakers (preferably mechanically and electrically interlocked). The

command for the breaker that connects the loads to the source B (BCB) must be taken
between terminals 1 and 3 of the JL connector. In this way, with the controller

24 ATS115-ATS115Plus Technical Manual

 unpowered, the contact opens and the BCB breaker separates the source B from the
loads. The command for the breaker that connects the loads to the source A (ACB)
must be taken between terminals 4 and 6 of the JL connector. In this way, with the
controller unpowered, the contact closes and the ACB breaker connects the loads to
the source A (normally mains). Set the P.0307 parameter to zero (the command can
always be reversed immediately) and set the pause interval that you want during the
switch in the P.0306 parameter. Two additional outputs can be used for the breakers
minimum coils management: the two functions are “2001 - Minimum coil ACB (NC)”
and “2031 - Minimum coil BCB”. These outputs are associated to the management
logics that depend on the plant configuration. ATS115 uses logics that avoid the not-
synchronized simultaneous closing of ACB and BCB; however, an external protection
logic shall be used for this purpose.

For the changeover management see par. 12.5.

If there is only one switch, the ACB output (terminals 4...6 of the JI) is not used, therefore
it can be associated to a different function (see par. 5.9.9).

5.7

By default, the JL connector is configured for two relay outputs connections that can be used
as start demands of the source A (START A – JL.1) and of the source B (START B – JL.3)
when connected to a genset. If they are not used as engine start command, two outputs are
reconfigurable by parameter for other purposes.

This connector allows the connection to the 5…6 outputs. They are positive 3A @30VDC relay
outputs with internal diode for the opening overvoltage damping. When the outputs are
operating, the relays lead to the output terminal the voltage supplied to the JL-2 terminal (it
must be a positive voltage, usually the controller voltage positive).

The status of the START A and START B outputs is displayed on page S.10 (0= output
inactive, 1= output active).

Terminal Output Type Parameter Default function

JL-1 Output 5 (START A) Relay 3 A P.3005 DOF.1001 – Start command A.

JL-2 Common (+)
JL-3 Output 6 (START B) Relay 3 A P.3006 DOF.1002 – Start command B.

ATS115-ATS115Plus Technical Manual 25

 5.8

The device runs four digital outputs, entirely programmable. When activated, they bring
themselves to the positive supply voltage on the JE supply terminal.
The rated capacity of each output is 500mA; the total power is, therefore, of 2A. Never exceed
these values during standard operation.

The outputs are independent and individually protected from overloads, short circuits, polarity
reversal and overheating. The overload protection limits the current peaks to an instantaneous
4A value, in order to allow the activation of loads that require a transient current greater than
the rated. If this condition persists, after 150us the thermal protection cuts in progressively,
until the output turning off.

With inductive loads (power relays, electromagnetic actuators), although some are already
present inside, it is advisable to use diodes for the damping of opening overvoltages.

All the current delivered by the outputs must be made available through the JE 2-+BATT;
make sure that any protection fuse on the supply plus has capacity and response time
suitable to power and protect both the outputs and the ATS115 in any condition of use.

The default functions of the JE outputs set on the controller are:

Terminal Output Parameter Default function

JE-1 Output 1 P.3001 DOF.3032 – Source A in tolerance.

JE-2 Output 2 P.3002 DOF.3033 – Source B in tolerance.
JE-3 Output 3 P.3003 DOF.0000 – Not used.
JE-4 Output 4 P.3004 DOF.0000 – Not used.

5.9
The four JE auxiliary outputs, the outputs JL_1, JL_3, JI_4 e JI_1 are completely configurable
individually.

The status of the digital outputs is displayed on page S.10 (0= output inactive, 1= output
active): at line 1…4 the connector JE-1..JE-4 outputs, at line START A, B the JL-1 and JL-3
outputs and at line ACB, BCB the JI-4 and JI-I outputs.

By default, all the outputs are activated when their function requires it (for example the output
of the source A start command runs when the genset connected to the source A has to be
activated).

Using the BoradPrg3, you can reverse the activation by simply ticking the “reverse polarity”
box on the top of the configuration page of every single output.

26 ATS115-ATS115Plus Technical Manual

 By operating directly on the controller, you can reverse anyway the logic of the outputs (still
individually for each output) including by means of the P.3000 parameter for the outputs on
the controller (a total of 8 bit):

• A zero-bit means that the output is normally on standby, it starts operating when the
related feature requires it.

• A one-bit means that the output is normally operating, it goes on standby when the related
function requires it.

The mapping of the outputs on the controller is:

BIT Value Output

0 1 Output 1

1 2 Output 2

2 4 Output 3

3 8 Output 4

4 16 Output 5 (JL-1)

5 32 Output 6 (JL_3)

6 64 Output ACB (JI_4)

7 128 Output BCB (JI_1)

Basically, if you want to invert an output logic, you need to add the related value in the related
parameter: for example, if you want to invert the output 3 and 4 on the controller, you need to
set P.3000 = 12 (that is 4+8).

As default, all bits are set to zero.

5.9.1 Functions configurable on the digital outputs

The digital outputs can be used directly as command for devices outside the controller, or for
reporting certain operating conditions.

The configuration can be carried out using parameters from P.3001 to P.3008.

Basically, AND/OR logics are a list of Boolean conditions (true/false, on/off, 1/0), which can be
configured by the operator (programming), that the controller evaluates and the result of which
can be assigned to a digital output or to a virtual digital input (see par. 5.9 and par. 5.5). In
order to use the AND/OR logics with a digital output, use the DOF.0103 function.

Note: the AND/OR logics cannot be configured directly from the controller panel, but
through a PC equipped with the BoardPrg3 software.

28 ATS115-ATS115Plus Technical Manual

The operator has to decide first if the list of conditions must be evaluated as AND (all must be
checked) or as OR (it is enough to check one condition). You cannot have AND/OR logics
mix (this option can be done using digital virtual inputs; see below).

You can add up to 30 conditions. Each condition can be denied individually: in the previous
figure, for instance, the controller will check that the digital input 3 and the digital output 8 are
both inactive. Here are the conditions that can be added:

• DI_XXX: logic states of all the digital inputs (physical or virtual).

• DO_XXX: logic states of all the digital outputs.

• AL_XXX: warnings/locks present.

• ST_XXX: internal states of the controller.

• AT_XXX: states concerning the thresholds on analogue measures (see par. 5.11.6).

The following table shows the list of the internal states available for the AND/OR logics.

Using the virtual digital inputs, it is possible to create mixed AND/OR logics (composed by
both AND and OR). Suppose you want to activate the digital output #1 when the digital inputs
#1 and #2 are both active, or when digital input #3 is active.

First we have to associate to the virtual digital input #1 (for instance) an AND/OR logic
configured as AND, which checks that the first two inputs are both active. Then we have to
associate to the digital output #1 an AND/OR logic configured as OR, which checks that the
virtual digital input #1 or the digital input #3 are active. In practice, the virtual digital input #1 is
used as “support” for the AND condition. In this case, you don’t need to associate a function
to the virtual digital input.

5.11

The device is provided with three inputs designed for the connection to the resistive-type
sensors JM-2, JM-3, JM-4. All analogue inputs are completely configurable and can be used
to acquire the generic values or as digital inputs.

Terminal Input Default function

JM-2 Input 1 AIF.0000 – Not used.

JM-3 Input 2 AIF.0000 – Not used.
JM-4 Input 3 AIF.0000 – Not used.
JL-4 Input 4 AIF.0000 – Not used.

Each input used as analogue is associated to a set of 8 parameters to define the type of
function, an alternative denomination and a series of thresholds and generic configurations
that can be used for different functions. For any detail, see par. 5.11.6.

For all of these measurements it is possible to define, by means of the BoardPrg3 program,
some settable curves, using at least two couples of resistance/value points of the measure,
see par.5.11.6.

It is also possible to configure the three inputs JM-2, JM-3 and JM-4 individually as additional
digital inputs that are activated when connected to ground. They will be displayed in the menu
of the digital inputs configuration and they will be managed in the same way of the other inputs;
see par. 5.11.6.

The three voltage values on the terminals and their value of the sensors resistance and of the
JM-1 voltage measured are displayed on page S.11; if an input is not configured, there will be
dashes on the display.

30 ATS115-ATS115Plus Technical Manual

 If one or more inputs are configured as digital, their status is displayed on page S.10 (0 = input
inactive, 1 = input active). The inputs which are not configured as digital are displayed with a
dash.
5.11.1 Input JM-1 Analogue Reference
It is not a real measure input: it is used together with the three inputs for resistive sensors. Its
purpose is to compensate for the lack of equipotentiality between the electric earthing of the
device (GND terminal) and the electric panel and the electric earthing of the genset, usually
generated by the voltage drop on the connection cables. In particular, this happens when the
connections between electric panel and engine are long and when there is a power flow in the
battery minus and ground connections, for example due to the presence of the battery charger
device inside the electric panel.

The system is able to efficiently compensate for both positive and negative potentials, ranging
between -2.7VDC and +4VDC, with sensors resistance values of 100 ohm. The range of
compensation increases for lower resistance values and decreases for higher resistance
values, being optimized for the resistance values present in normal operating conditions of the
system.

The measure of the voltage with respect to the GND terminal is displayed on page S.11, under
item JM1; the measuring range of the system, and consequently the value indicated, can be
higher than the one useful for the compensation, as mentioned above.

The input measures the potential of the common ground point (negative) of the resistive
sensors, which for the sensors on the engine is directly represented by the engine itself or by
the chassis of the genset. Therefore, JM-1 can be connected to a grounding system or to a
bolt on the engine.

If the minus of one or more sensors is isolated from the engine or from the genset chassis,
you need to connect the JM-1 to the return of the sensor and also to the negative electric
ground of the engine or to the negative limit of the battery.

Note: this connection should be made using a dedicated wire having the shortest length
possible. Avoid to make the wire pass near high power cables.
5.11.2 Input JM-2 (AI 1)
The input has a useful resistance measurement range between 0 and 1500 ohm; within this
range the measurement error guaranteed is less than 1%, with a voltage to the JM-1 terminal
with respect to the GND=0. Higher resistance values can be measured, although with
gradually decreasing precision.

It can be configured with the P.4001 parameter as:

- AIF.0000 Not used

- AIF.0100 When used as digital input, it is active when connected to GND, not
active when left floating (for its use see par. 5.4)

- AIF.2001 Generic sensor (page 1)

- AIF.2003 Generic sensor (page 2)

- AIF.2005 Generic sensor (page 3)

- AIF.2051 Generic sensor

The configuration of the sensor as type 0, 100 can be done directly from the device
keyboard; all the others need the use of the BoardPrg3 program to define or load the
characteristic curve of the sensor (see par.6).

The configurations AIF.2001, AIF.2002 and AIF.2005 “Generic sensor (page x)” allow to select
in which page of the display menu E the measure acquired will be displayed (page 1 = first
page available, page 2 = second page available, etc.).

 5.11.3 Input JM-3 (AI 2)
The input has a useful resistance measurement range between 0 and 2000 ohm; within this
range the measurement error guaranteed is less than 1%, with a voltage to the JM-1 terminal
with respect to the GND=0. Higher resistance values can be measured, although with
gradually decreasing precision.

It can be configured with the P.4009 parameter as:

- AIF.0000 Not used

5.11.4 Input JM-4 (AI 3)
The input has a useful resistance measurement range between 0 and 1700 ohm; within this
range the measurement error guaranteed is less than 1%, with a voltage to the JM-1 terminal
with respect to the GND=0. Higher resistance values can be measured, although with
gradually decreasing precision.

It can be configured with the P.4017 parameter as:

- AIF.0000 Not used

active when left floating (for its use see par. 5.4)

5.11.5 Input JL-4 (AI 4)
The input AI 4 (on the terminal JL_4) can be configured as auxiliary analogue input in voltage,
with measurement range 0-32VDC with respect to the controller supply negative (GND).

It can be configured with the P.4017 parameter as:

- AIF.0000 Not used

in which page of the display menu E the measure acquired will be displayed (page 1 = first
page available, page 2 = second page available, etc.).
5.11.6 Analogue inputs configuration
You can apply a conversion curve to all the physical analogue inputs JM-2, JM-3, JM-4 and
JL-4 (not to the virtual analogue inputs).

Each analogue input, both physical and virtual, is associated to eight parameters; here below
as example the ones related to input JM-2; for the parameters of the analogue virtual inputs,
see document [1] or the I/O BoardPrg3 configuration page.

NOTE: On BoardPrg3 the parameters are all displayed only when the input is actually
configured as analogue input and not, for example, as digital.

We have:

• One parameter which configures its function (P.4017 for input JM-2).

• One parameter which configures any message to be shown on the display (P.4018
for input JM-2).

• Two thresholds consisting of three parameters each:

▪ One parameter which configures the threshold value (P.4019 and P.4022 for
input JM-2).

▪ One parameter which configures the delay for managing the “out of threshold”
(P.4020 and P.4023 for input JM-2).

▪ One parameter which configures the checking options and the actions in case
of “out of threshold” (P.4021 and P.4024 for input JM-2).

The parameter containing the message for a certain analogue input (in the example above,
what is written in the P.4002 parameter) is displayed and used by the controller every time the
thresholds are used to activate warnings and/or alarms (see below); it is also used for the
following functions of the analogue inputs: AIF.2001, AIF.2003 and AIF.2005 of the type
“Generic sensor (page X)”. In this case the measure acquired will be displayed according to
the X value (1, 2 or 3) on pages M.09, M.10, M.11, preceded by the message configured.

Note: You can also use the AIF.2051 function instead of the previous three. In this case,
the measure acquired will not be displayed on M.09, M.10, M.11; however, it can be still
used with the thresholds to manage digital outputs and activate warnings/locks.

The two thresholds are completely independent among each other. The third parameter of
each threshold is a “bit” parameter that allows to associate to each threshold the following
options:

• Bit 1. If this bit is “OFF”, the controller checks if the measure is higher than the
threshold. If this bit is “ON”, the controller checks if the measure is lower than the
threshold.

ATS115-ATS115Plus Technical Manual 33

 • Bit 2. If this bit is “OFF”, the controller sets to OFF the internal status related to this
analogue measure if the measure is “out of threshold”. If this bit is “ON”, the controller
sets to ON the internal status related to this analogue measure if the measure is “out
of threshold”.

• Bit 5. If this bit is “ON”, the controller issues a warning if the measure is “out of
threshold”.

• Bit 8. If this bit is “ON”, the controller issues a lock command if the measure is “out of
threshold”.

• Bit 10. If this bit is “ON”, the controller checks that ACB is closed to activate any
warning/lock configured with previous bits.

• Bit 11. If this bit is “ON”, the controller checks that the GCB is closed, to activate
possible warnings/locks configured with the previous bits.

• Bit 14. If this bit is “ON”, to activate any warning/lock configured with the previous bits,
the controller checks the status of any digital input configured with the function “DIF.
2705 - Disable the protections on the analogue measures”. The warnings/locks will be
activated if no digital input is configured as such, or if they are all OFF.

You can set any combination of these bit.

Using the two thresholds and the AND/OR logics together, you can activate a digital output
regarding the value of an analogue measure, with hysteresis. Suppose you want to activate a
digital output if the frequency exceeds 50.5 Hz. First of all you have to maintain a minimum
hysteresis on the threshold, otherwise, when the frequency is close to the threshold, the output
will continue to switch on and off, due to minimum variations of the frequency itself. Then,
suppose you want to activate the output if the frequency exceeds 50.5 Hz and deactivate the
output if the frequency is lower than 50.3 Hz. In order to do that we can use, for example, the
virtual analogue input #1 (see par. 5.5), which has been configured to contain the frequency.

Set the parameters as follows:

• P.4051 (function #1): 4001 (AIF.4001).

• P.4052 (message #1): “”.

• P.4053 (threshold #1): 50.5 Hz

• P.4054 (delay #1): 0.5 sec

• P.4055 (configuration #1): 0002 (bit 0 OFF, bit 1 ON)

• P.4056 (threshold #2): 50.3 Hz

• P.4057 (delay #2): 0.5 sec

• P.4058 (configuration #2): 0001 (bit 0 ON, bit 1 OFF)

The first threshold is used to activate the internal status related to the analogue input. Looking
at the configuration parameter you can see that:

• Bit 0 OFF (check that the measure is higher than the threshold).

• Bit 1 ON (activate the internal status in “out of threshold” condition).

The second threshold is used to deactivate the internal status related to the analogue input.
Looking at the configuration parameter you can see that:

• Bit 0 ON (check that the measure is lower than the threshold).

• Bit 1 OFF (deactivate the internal status in “out of threshold” condition).

34 ATS115-ATS115Plus Technical Manual

 With the previous programming, the controller activates the internal status related to the
analogue input when the measure is greater than 50.5 Hz for 0,5 seconds; it deactivates the
internal status when the measure is less than 50.3 Hz for 0,5 seconds.

Using the AND/OR logics (see par. 5.10) you can “copy” the internal status on a physical
output.

5.12
The controller also manages 8 virtual analogue inputs. They are managed by the controller
just as if they were physical inputs (with no limitation), but the status of the virtual inputs is not
acquired from the hardware, but it is determined through the software. In fact, by means of the
“function” parameter of each virtual analogue input, it is possible to “copy” one of the internal
measures made available by the controller in the analogue input:

• AVF.4001 - "Source A frequency"

• AVF.4006 - "L1-L2 Source A voltage"

• AVF.4007 - "L2-L3 Source A voltage"

• AVF.4008 - "L3-L1 Source A voltage"

• AVF.4009 - "L-L Source A medium voltage"

• AVF.4012 - "Source B frequency"

• AVF.4017 - "L1-L2 Source B voltage"

• AVF.4018 - "L2-L3 Source B voltage"

• AVF.4019 - "L3-L1 Source B voltage"

• AVF.4020 - "L-L Source B medium voltage"

• AVF.4023 - "Current phase L1"

• AVF.4024 - "Current phase L2"

• AVF.4025 - "Current phase L3"

• AVF.4026 - " Auxiliary current (including N)"

• AVF.4031 - "Active power L1"

• AVF.4032 - "Active power L2"

• AVF.4033 - "Active power L3"

• AVF.4034 - "Total active power"

• AVF.4041 - "Total apparent power"

• AVF.4047 - "Total reactive power"

• AVF.4058 - "Total power factor"

• AVF.4059 - "Total Cosfi"

• AVF.4063 - "Partial active energy of the Source A"

• AVF.4065 - "Partial reactive energy of the Source A"

• AVF.4069 - "Partial active energy of the Source B"

• AVF.4071 - "Partial reactive energy of the Source B"

ATS115-ATS115Plus Technical Manual 35

 • AVF.4105 - "Battery voltage measured by the controller"

• AVF.4112 - "Source A operating hours"

• AVF.4113 - "Source B operating hours"

• AVF.4116 - "Engine partial operating hours left before maintenance”

You cannot use these functions to configure physical analogue inputs.

The purpose of the virtual analogue inputs is double:

• Allowing the issuing of warnings/locks related to the internal measures available.

• Activating digital outputs based on the value of the internal measures available.

See example in par. 5.11.6.

6.
The conversion curves are a tool which allow you to convert a numerical value into another
numerical value. They can be used to convert the value acquired from a resistive analogue
input (physical) to the real unit of measure of the sensor.

Note: the conversion curves cannot be configured directly from the controller board,
but through the Board Prg3 software equipped on a PC.

Once created, the curves can be saved to be reused in the future, including on other
ATS115 controllers.

The figure above shows a conversion curve associated to a resistive analogue input. The
analogue input has been configured with the AIF.2051 function – “Generic sensor”. In this
configuration, the converted value will amount at 10 for a resistance value equal to 45 Ohm or

36 ATS115-ATS115Plus Technical Manual

lower, 90 for a value equal to 55 Ohm or higher; for frequency values ranging between 45
Ohm and 55 Ohm, the converted value will be between 10 and 90.

You can add up to 32 points in the graph, creating also non-linear curves. As in the example,
the curve configured has two horizontal segments at the beginning and at the end, obtained
by putting two equal values in the “After” column, which correspond to two different values in
the “Before” column. This is not obligatory, but it allows to set a saturation limit on one or both
ends of the curve. In fact, the controller board extends the first and last segments of the curve
to infinity. Being horizontal, whatever value the measure “to convert” assumes, you will obtain
the same value of the “converted” measure. In the previous example, for any measure lower
than 45 Ohm, the converted value will be set at 10. In the example above, if you removed the
first point (44 Ohm 10), the horizontal segment would not be at the beginning of the curve: in
this case, if the resistance dropped below 45 Ohm, the converted value would drop below 10.

The BoardPrg3 software allows (by means of the first buttons on the left top) to save the curve
on file, in order to be able to use it again in other applications. So, it is possible to create an
archive of the conversions associated to the sensors used.

In case the curve is associated to a physical analogue input configured with the AIF.2001,
AIF.2003 and AIF.2005 (“Generic sensor”) functions, the converted measure will be displayed
on pages M.09, M.10 and M.11: in this case, it is possible to specify (through the conversion
curve) how many decimal digits the displayed value will have, as well as its unit of measure).

The connection to the SOURCE A is made through the JH connector of the controller.

Tri-phase connection:

• Connect phase L1 (or R) to terminal 3 of JH connector.

• Connect phase L2 (or S) to terminal 2 of JH connector.

• Connect phase L3 (or T) to terminal 1 of JH connector.

• Connect neutral (if any) (N) to terminal 4 of JH connector.

Single-phase connection:

• Connect phase (L) to terminal 3 of JH connector.

• Connect neutral (N) to terminal 4 of JH connector.

The tri-phase/single-phase selection is allowed by the P.0101 parameter.

For CAT.III application, the maximum applicable voltage is 300 Vac (phase-to-neutral)
and 520 Vac (phase-to-phase). The maximum voltage to ground is 300 Vac.

The controller board uses the L1 phase (terminal JH-3) to measure the source A frequency.

If you need to connect higher voltages, you must use voltage transients (VTs) with a secondary
voltage that does not exceed the previous limits. The primary and secondary nominal VT
voltages are configurable with P.0103 and P.0104 parameters. It is recommended to use the
VTs that, at nominal voltage, give about 400 Vac on the secondary (not to reduce de measure
precision of the controller).

It is optionally possible to order a version of the device with max 100Vac (phase-phase) voltage
inputs to be used with VT with 100V secondary ones. In this case it is necessary to configure
P.0152 parameter for 100V working.

Warning! Do not connect devices provided with optional 100V max inputs directly to
mains or to 400V bus not to damage the device.

38 ATS115-ATS115Plus Technical Manual

7.1 Measurement of the SOURCE A neutral
The device, in three-phase connection, can work both with and without neutral connection; the
selection is made through the P.0120 parameter.

If the system is configured with neutral connection, the neutral voltage is measured in relation
to GND. The values of the V1-N, V2-N and V3-N phase voltages and the VN neutral voltage
in relation to GND for the mains are displayed on page M.03.

If the device is configured not to measure the neutral voltage, then page M.03 will not be
displayed.

The connection to the SOURCE B (mains or genset) is made through the JG connector of the
controller.

Tri-phase connection:

• Connect phase L1 (or R) to terminal 3 of JG connector.

• Connect phase L2 (or S) to terminal 2 of JG connector.

• Connect phase L3 (or T) to terminal 1 of JG connector.

• Connect neutral (if any) (N) to terminal 4 of JG connector.

Single-phase connection:

• Connect phase (L) to terminal 3 of JG connector.

• Connect neutral (N) to terminal 4 of JG connector.

The tri-phase/single-phase selection is allowed by the P.0201 parameter.

For CAT.III application, the maximum applicable voltage is 300 Vac (phase-to-neutral)
and 520 Vac (phase-to-phase). The maximum voltage to ground is 300 Vac.

The controller board uses the L1 phase (terminal JG-3) to measure the source B frequency.

If you need to connect higher voltages, you must use voltage transients (VTs) with a secondary

8.1 Measurement of the SOURCE B neutral

The device, in three-phase connection, can work both with and without neutral connection; the
selection is made through the P.0220 parameter.

If the system is configured with neutral connection, the neutral voltage is measured in relation
to GND.

The values of the V1-N, V2-N and V3-N phase voltages and the VN neutral voltage in relation
to GND for the mains are displayed on page M.05.

If the device is configured not to measure the neutral voltage, then page M.05 will not be
displayed.

9.

The current measurement shall be made exclusively by means of current transformers

(CTs). Do not connect mains voltage conductors to JF.

Currents transformers having a maximum nominal current of approximately 5 Ac on the

secondary side can preserve the measurement precision of the controller. Any current
measurement needs a power of about 1VA; however, 5VA CTs are recommended to
compensate for leaks along the connection cables.

The maximum current that the device can measure directly is of 5.3Ac, beyond which the
measurement circuit gets saturated. The controller board is still able to measure, but with
gradually decreasing precision down to about 15 Ac, only for transient situations, such as
overcurrents or short circuit currents on the system, using an algorithm to compensate for the
saturation of the measurement circuits.

40 ATS115-ATS115Plus Technical Manual

 The CTs for the measurement of the three currents have only one terminal clip for the JF-4
return current; the fourth auxiliary current has a return separated from the other three through
the JF-7 terminal clip.

The measurement is carried out by shunt.

IMPORTANT: the returns of all CTs (including the auxiliary JF-7) must also be
connected to the genset starting battery minus.

If the CTs has to be connected to other devices in addition to the ATS115, then the ATS115
must be the last in the series. In order to acquire the currents of the three phases of the
generator, the JD connector is used:

• Connect one CT terminal connected to the L1 phase to terminal JF-1.

• Connect one CT terminal connected to the L2 phase to terminal JF-2.

• Connect one CT terminal connected to the L3 phase to terminal JF-3.

• Connect all three TA returns to terminal JF-4.

For single-phase connection, terminals JF-2 and JF-3 should not be connected.

The parameters P.0302 and P.0310 are used to set the current values of the CTs primary and
secondary.

Using the P.0311 parameter you can define whether the CTs on the three phases are
positioned on the source A or B (as shown in the drawing above) or on the load, in order to
measure the power absorbed by the mains too. This also has an effect on the operation
sequence and on the display of symbols and currents and power/energy measures that appear
on the menu pages M.01, M.06, M.07, M.08 and M.09.

9.1 Auxiliary current

The device allows for acquiring a fourth measure of current, available for example for a
differential protection. By default, the fourth measure is not used.

The board is configured for the connection of a current transformer (C.T.) with 5A secondary
for the measure of the current: if it is required to use a toroid (instead of a C.T.), it is necessary
to ask for the special option in phase of order (E6202111000XX).

The parameters P.0312 and P.0313 define the currents of the CT primary and secondary for
the auxiliary current.

The P.0311 parameter defines where the auxiliary current is measured:

0- On the Source A
1- On the Source B
2- On the Loads

The P.0314 parameter allows you to select if and how the auxiliary current is used:

0- Not used
1- General use
2- Neutral

Settings 1 and 2 allow to establish a threshold (parameters P.0367 and P.0368) and to define
what action should be taken when it exceeds. The “2-Neutral” setting on the generator also
allows to implement the current differential protection (see 9.2).

It is possible to configure a digital input with the DIF.2704 function – “Disable the protections
on the 4th current”: If the input is active, the thresholds, even if set, are ignored and no faults
are generated in case the thresholds are exceeded.

The activation of the protection creates a warning, but it does not issue any switch.

ATS115-ATS115Plus Technical Manual 41

 9.2 Differential current
To use the current differential protection, the CT of the auxiliary current should measure the
neutral current the P.0134 parameter should be set as “2 - Neutral”.

In that way, the device calculates the vector sum of all the four currents measured. Therefore,
it detects and calculates any imbalance, allowing to implement, by means of the parameters
P.0377 and P.0378, a threshold for the maximum current differential protection.

The activation of the protection creates a warning, but it does not issue any switch.

9.3 Auxiliary and/or differential maximum current action

Currently, the controller does not issue any action in case of activation of the protections for
the auxiliary and/or differential maximum current.

The action to issue must be configured using the AND/OR logics associated to virtual inputs.
In the example below, when the warning “Source A auxiliary/neutral maximum current” or
“Source A differential maximum current” is activated the warning “Source A fault” is signalled
through the virtual input 1, which automatically demands the switch on the other source too (if
available).

Similarly combining the same logic to the virtual analogue input 2, the result will be the same
for the source B.

If the protection is activated on both sources, the controller keeps the mains circuit breaker
closed as priority, while it keeps both circuit breakers opened if the system is configured with
two gensets.

10.
The device is supplied with many communication ports for the connection to PC, modem,
networks etc. Some of these ports are optional and could therefore not be present on the
device in your possession.

Normally, the device is only equipped with the USB connection type B for the PC FW upgrade
and for the parameters programming (JB connector).

According to the versions and options demanded, it can be equipped with:

- RJ45 connector for Ethernet 10/100 connections.

- RS232 serial connection (max 12m), see par. 10.1.

- RS485 insulated serial connection; 1200m max connection length, in optimal conditions.
The 120 Ohm terminal resistor is included; in order to insert it, you just need to connect the 1
and 2 JO pins between them. It is recommended the use of shielded cable with 120 Ohm
impedance (for example BELDEN 3105A Multi-conductor-EIA Industrial RS-485PLT/CM).
See par. 10.3

For the details concerning the communications see the specific paragraphs and the document
[2].

10.1

The USB protocol specifications do not allow its permanent use in the industrial sector, due to
limited length of the cable and to the relatively elevated sensitivity to electrical disturbances,
including the PC side. For this reason, the USB connection cable must be inserted only
when it is necessary to operate on the device and it must be removed from the JB
connector when the operation is finished.

The USB connection to a PC is used for two purposes:

- Enabling the device firmware

- Parameters programming

The firmware insertion/replacement of the device is a specific SICES srl operation; in addition to
the operating FW to insert, it requires a particular procedure and specific programs and normally
this procedure must not be carried out by the installer, except in specific situations previously
agreed on with SICES.

The USB port can be used for programming the parameters with the BoardPrg3 program, as an
alternative to the serial RS232/RS485 connection or to Ethernet.
The PC to be connected must have the CDC_Sices_Win.inf driver installed, which is supplied
by SICES; for driver installation refer to document [5].
After that, the PC will acknowledge the ATS115 as new serial port, usable just as if it was a
RS232 serial.

10.2

The RS232 JA connector (serial port 1) can be used for interfacing with an external device
provided with RS232 interface, such as a modem or a PC. The maximum distance of the
connection is 12m.

The connection can be used for programming the parameters of the device through the
BoardPrg3 program, or for connecting to a supervising program, such as SicesSupervisor.

For the functions and protocols implemented, refer to document [2]. Below the diagram of the
connector:

• JA_01: not connected

• JA_02: RXD

• JA_03: TXD

• JA_04: DTR

• JA_05: GND

• JA_06: DSR

• JA_07: RTS

• JA_08: not connected

• JA_09: not connected

To configure the use of the serial port 1, you need to configure the parameters:

P.0451 Usage of the serial port (1)

P.0452 Modbus address (1)
P.0453 Baud rate (1)
P.0454 Settings (1)
P.0470 Order of the Modbus registers (1)

The description of these parameters is in document [3].

10.3

The device can be equipped with a RS485 connector (serial port 2), which is insulated and
separated from serial port 1 (RS232) and can be used to connect via Modbus to a PC or other
devices.
For the details concerning the RS485 connection, its use and the programming of the
parameters, refer to document [3].

Connections:
JO-3 Connection RS485 A
JO-2 Connection RS485 B

The RS485 connection needs a 120 Ohm terminal resistor on both ends of the cable. The
device has the resistor included; to enable it, you just need to jumper connect JO-1 and JO-2
to each other.

You cannot connect a modem on the serial port 2; as for the rest, you can use it for the same
connections as the RS232 serial port, using RS485/RS232 or RS485/USB adaptors where
necessary.

The isolation ensures the safe operation of the connection, including between remote devices
and devices with earth potentials different from that of the ATS115.
The maximum length of the connection is 1200m; however, it depends on the transmission
baud rate set. A specific shielded cable should be used (see par. 4.2) with grounded shielding
mesh.

To configure the use of the serial port 1, you need to configure the parameters:
P.0472 Modbus address (2)
P.0473 Baud rate (2)
P.0474 Settings (2)
P.0475 Order of the Modbus registers (2)

The description of these parameters is found in document [3].

ATS115 is equipped with a RJ45 for the data exchange connection via Ethernet network.
For the details regarding the network connection and the protocol, refer to document [2].

It is possible to connect the device to a LAN network, or directly to a PC (point to point connection).
The connection allows the use of the SicesSupervisor SWs, the configuration of the BoardPrg3

The mode identifier (1a), and the page identifier (1b) identify and refer to the page so there is no chance of
error. The title (1c) provides a description in the current language of the content of the page.

Pressing the ESC/SHIFT button, the controller replaces the title (while the button is held) with a status
message. By double clicking the ESC/SHIFT button, the title is replaced with a status message so long as
you remain on that page. If the bit 6 of parameter P.0495 is activated, the controller automatically replaces
the title with a status message if there is at least one pending status message with a waiting time
(countdown); if the operator selects a new page, the controller shows the title for two seconds, then it shows
the status message again.

The system status (2) displays part of the information of the page S.01 (STATUS) that is useful to the
operator, as it can be displayed even if other pages or display mode are being accessed.

11.5.1 Programming (P.xx)
The controller manages a high number of parameters that allow the manufacturer, the installer
or the final user to configure it in order to adapt it to specific system requirements. This
document does not contain the parameters list (even though many of them are quoted in the
description of the controller functions); the list is available in the document [1], where they’re
described in detail. In this document the general programming structure and the operating
procedure to read and/or modify parameters are described.

ATS115-ATS115Plus Technical Manual 53

 To access the parameters change mode, scroll the UP and DOWN buttons to menu P.03 -
Programming and press ACK/ENTER to start.

To exit the programming menu and to return to the main screen press the ESC button.

WARNING: The assignment of an incorrect value to one or more parameters

can cause malfunctions or damages to things or injuries to people. The
parameters must be changed by qualified personnel only. Parameters can be
protected by password (ref. to par. 11.5.1.2).

Each programming parameter Ref. 3 has a 4-digit numeric code associated (e.g. P.0301) to
identify the variables regardless of the language used. The current value of the parameter is
displayed below the description Ref.4 (between brackets).

The first line Ref.2, below the upper status bar, allows to identify the current menu using the
ID number of the menu and the associated text. A pair of numbers is displayed on the right of
this line, 2/ 06 in the example in fig. 3.

The first indicates which entry in the menu is selected or which page is displayed; the second
indicates how many entries or pages can be displayed in the current menu/submenu.

When pressing the ESC/SHIFT button, the first line Ref.1 is temporarily replaced by a status
message concerning the engine sequence.

11.5.1.2 Protection password

If the password is lost, you can reconfigure it using the higher level password. Contact
our service centre if the “MANUFACTURER” password is lost.

The first page (000-Access Code) of the SYSTEM menu requires the setting of the access
code if one or several passwords have been assigned (available with the path P.03
PROGRAMMING\ 1.SYSTEM\ 1.1 Security\ 1.1.1 Authentication).

The password is not assigned if equal to 0 (only valid for Manufacturer, Installer and User
passwords).

The pages corresponding to the Password setting are displayed only if you are authorized to
make changes in the SYSTEM sub-menu (with the path P.03 PROGRAMMING\ 1.SYSTEM\
1.1 Security\ 1.1.2 Password).

In programming mode, in case the page for the password change is not displayed when you
enter the Password, press ESC to return to the previous menu and try to open the page again.
The set access code remains in memory for about 10 minutes after the programming has been
completed. Then it must be entered again to access the programming mode.

54 ATS115-ATS115Plus Technical Manual

 The access to the programming mode can be controlled by 4 different PASSWORD levels,
listed in priority order.

1. Manufacturer password
2. Installer password
3. User password
4. Serial ports password

1. As MANUFACTURER, it is possible to display and change all the three passwords

(MANUFACTURER, INSTALLER and USER) and change all parameters concerning
configuration, protections and sequences.

2. As INSTALLER, it is possible to display and change the INSTALLER and USER passwords
and change all parameters concerning the configuration, but the parameters that need the
MANUFACTURER password.

3. As USER, it is possible to display and change the USER password only, and access the
parameters that allow to adjust sequence times and basic configurations, without changing
the plant operation principle in any way.

4. The “Serial Ports” password can only be set and/or seen through the user panel; when
set, this password prevents any command from the serial line.

Each parameter of the controller is associated to a user type (in the document [1] “SICES
EAAM0479xxXA - Parameter Table ATS115” this association is shown in the "ACC” column
with a “C” for Manufacturer, "I” for Installer and "U” for User).

A parameter associated to the manufacturer can be modified only by the manufacturer. A

parameter associated to the installer can be modified by the manufacturer and the installer. A
parameter associated to the user can be modified by the manufacturer, the installer and the
user.

According to the general rule, parameters can be changed only when the controller is on
“OFF_RESET”. Except for some parameters that can be changed regardless of the status of
the controller, including with the engine running. Generally, if a parameter cannot be changed,
it will be enclosed between < and >; instead, if it can be modified, it will be enclosed between
[ and ] : that is valid also for the restrictions due to password.

If the operator has to change a parameter, he/she must put first the proper password in the
P.0000 parameter (“1.1.1 - Authentication”), so that the controller can recognize it as
“Manufacturer”, “Installer” or “User”. The parameter is available, with the controller in
OFF/RESET-PROGRAM mode, at path: P.03 PROGRAMMING\1.SYSTEM\1.1
Security\1.1.1 Authentication. After completing this operation, it will be possible to change
the required parameters. The access code entered remains saved in P.0000 for about 10
minutes since the end of programming. After this time, the code is automatically reset to zero
and must be re-entered to access the programming again.

It is possible to customize the passwords for the three types of users, through the parameters
P.0001 (manufacturer), P.0002 (installer) and P.0003 (user), available with the path P.03
PROGRAMMING\1.SYSTEM\1.1 Security\1.1.2 Password configuration. The value "0” for
these parameters means no password set. The following examples show all the combinations
for the passwords assignment.

ATS115-ATS115Plus Technical Manual 55

 Example 1: P.0001=0 P.0002=0 P.0003=0

Any operator is seen as a "manufacturer”, with no need of setting anything in “P.0000-

Access code”. Therefore all the parameters are changeable from anyone (this is the
default mode).

Example 2: P.0001=0 P.0002=0 P.0003=”uuu”

No parameter modification is allowed. When entering the “uuu” code in “P.0000 -

Access code”, the operator is identified as “User” but, since no password is associated
to “Installer” and “Manufacturer”, the controller acknowledges him/her as
"Manufacturer”. After entering the code, all parameters are changeable.

Example 3: P.0001=0 P.0002=”iii” P.0003=”uuu”

No parameter modification is allowed. When entering “uuu” in “P.0000 - Access code”,

the operator is identified as “User” and allowed to change all parameters associated
to the user. By entering “iii” instead, the operator is identified as "Installer” but, since
no password is associated to the manufacturer, the controller identifies him/her as
"Manufacturer”. After entering the code all parameters are changeable.

Example 4: P.0001=”ccc” P.0002=”iii” P.0003=”uuu”

No parameter modification is allowed. When entering “uuu” in “P.0000 - Access code”,

the operator is identified as “User” and allowed to change all parameters associated
to the user. By entering “iii” instead, the operator is identified as "Installer” and allowed
to change all parameters associated to the installer and the user. By entering “ccc”,
the operator is identified as “Manufacturer” and allowed to change all controller
parameters.

Example 5: P.0001=”ccc” P.0002=0 P.0003=0

As no password is associated to the User and the Installer, programming the relevant
parameters is allowed without entering anything in “P.0000 - Access code”. To change
the parameters associated to Manufacturer, simply enter “ccc” in “P.0000-Access
code”.

Example 6: P.0001=0 P.0002=”iii” P.0003=0

As no password is associated to the User, programming the relevant parameters is

allowed without entering anything in “P.0000 - Access code”. By entering “iii” in
“P.0000 - Access code”, the operator is identified as “Installer” but, since no password
is associated to the manufacturer, the controller still identifies him/her as
"manufacturer”. After entering the code all parameters are changeable.

Example 7: P.0001=”ccc” P.0002=”iii” P.0003=0

As no password is associated to the User, programming the relevant parameters is

allowed without entering anything in “P.0000 - Access code”. By entering “iii” in
“P.0000 - Access code”, the operator is identified as “Installer” and allowed to change
all parameters associated to the installer and the user. By entering “ccc” in P.0000,
the operator is identified as “Manufacturer” and allowed to change all controller
parameters.

56 ATS115-ATS115Plus Technical Manual

 Example 8: P.0001=”ccc” P.0002=000 P.0003=”uuu”

No parameter modification is allowed. When entering “uuu” in “P.0000 - Access code”,

the operator is identified as “User” but, since no password is associated to the installer,
the controller still identifies him/her as “Installer”. The parameters associated to the
installer and the user can therefore be changed. By entering “ccc”, the operator is
identified as “Manufacturer” and allowed to change all controller parameters.

The parameter value can always be read, but it can be modified only in case the
"P.0000” contains a proper password. Parameters P.0001, P.0002, P.0003 and P.0469
(serial ports password) are excluded: they are not even displayed in case the "P.0000”
does not contain a proper password.

The P.0469 parameter – “Serial ports password” can only be displayed and/or changed
through the operator panel, and with at least the Installer rights.

When accessing the programming and setting the password ("P.0000), parameters
P.0001, P.0002 and P.0003 may not be displayed immediately. To enable the
visualisation, return to the previous menu and then re-enter.

In case the code set as password is forgotten, the access can only be recovered with
the higher level password. Otherwise (or in the event the manufacturer password is
lost), you need to send the controller back to the factory to have its associated
programming functions unlocked.

This is the reason why we recommend to set at least the “Manufacturer” password
(P.0001): in fact, in case someone else sets up this password, or a lower level one (even
unwillingly) without providing information, no parameter modification will be possible
anymore. Instead, knowing the “manufacturer” password, it will be possible to cancel
or change the other passwords.

11.5.1.3 Operating procedure

This procedure will describe the keyboard and the display use.

P.07 PROGRAMMING |
Main Menu 1/05

1 System
2 Sequence
3 Protections
4 Auxiliary functions

• The 1-SYSTEM menu allows to show how the controller connects to sources (mains or
genset) and the kind of plant. The correct setting of these parameters is paramount as
almost all protection activation thresholds are expressed as a percentage of these
parameters. In it there is the 1.6-INPUTS/OUTPUTS menu that allows to set how the
controller has to use the different inputs and outputs available (combining each of them to
the required function).

• Working sequence configuration can be modified through the 2-SEQUENCE menu. In this
menu it is possible to set threshold percentages and acquisition times, plus
enabling/disabling operation sequences related functions.

• Protections management is accessible through the 3-PROTECTION menu. As to this, it is

important to know that, in order to enable/disable a protection, you just have to the
associated time, leaving the threshold unchanged: by setting the time to zero, the

ATS115-ATS115Plus Technical Manual 57

 protection is disabled. However, this general rule provides some exceptions. Refer to the
chapter on faults (par.13), which describes the method to disable each of the faults.

• All operations not related to system configuration, sequence, protections and

inputs/outputs can be performed through the menu 4-AUXILIARY FUNCTIONS. This
menu contains other menus used for configuring engine auxiliary functions, calendars,
timers, history logs and serial communication.

11.5.1.4 Access to programming

The programming is accessible with the controller in any operation state, while parameters
can only be modified, in general, with the board on OFF/RESET.
To enter the programming mode, use the UP ▲ and DOWN ▼ buttons till the base
PROGRAMMING mode (P.03) screen is displayed.

When in a mode that limits the use of vertical scrolling buttons, it could be necessary to press
the ESC button one or several times (this situation can occur while displaying history logs or
during some particular operations, such as setting the fuel pump control mode).

Then, press ENTER to access the programming.

The menu or the variable selected before the last exit from programming are automatically
displayed when starting the procedure (the main menu is displayed the first time you access).
This is true if the programming procedure has been previously left by changing the operation
mode of the controller in MAN or AUTO, or after the maximum time with no programming
operation, or keeping the ESC button pressed for more than two seconds.

11.5.1.5 Menu selection

Current menu name, selected menu item and number of menu items are always displayed in
the second line. Menu items (submenus) are displayed in the following lines. The item selected
is displayed in REVERSE. Use the ▲ and ▼ buttons to cyclically scroll through the menu to
lower and upper index items (i.e. pressing ▲ from the first item to the last one and vice versa).

Press ENTER to access the selected (highlighted) submenu. Press ESC to leave the menu
(back to the previous menu or to the base screen if exiting programming in the main menu).

11.5.1.6 Parameters selection

Current menu name (for example the “1-SYSTEM” menu), selected menu item and number of
menu items are always displayed in the second line. The following lines are used to display a
single parameter. In particular:

• The unambiguous parameter code (three decimal digits), followed by the description
in the current language, is shown in the fourth and fifth line.

• The sixth line shows, between brackets, the variable value aligned to the right side
“< >”.

• For some parameters, the eighth line shows a value which is related, in some way,
to the actual parameter value. For example, in the case of the genset rated power, it
shows the rated plant current, which is derived from the rated genset voltage (P.
0102) and from the parameter itself (rated power, P.0106). Sometimes, this additional
measure can be displayed when the parameter is a percentage of other values, in
order to show its absolute value.

Use the ▲ and ▼ buttons to cyclically scroll the menu to the lower and the upper index items.
Press the ENTER button to enable the parameter modification procedure (see the following
paragraph). Press the ESC button to leave the menu (going back to the previous menu).

58 ATS115-ATS115Plus Technical Manual

11.5.1.7 Modify a parameter
You may only modify the parameters displayed between square brackets ([ ]). A parameter
between major/minor symbols (< >) cannot be modified. In this case, it could be necessary to
set an appropriate password or to stop the genset.

In case of changeable parameter, press the ENTER button; the square brackets ([ ]) enclosing
the value will blink to signal that the modification is in progress. In order to confirm the new
value, press again the ENTER button; to abort the change and go back to the original value,
press the ESC button.

The types of parameters are the following:

• Bits: Some parameters are managed with bits. Each bit set to 1 enables a function
and each bit set to 0 disables a function. Each bit is assigned to a value. The
parameter must be set at the result of the sum of the values associated to the functions
you require to enable. 8 bits can be used. The description of these parameters is
shown in a table like the one below:

Bit Value Description

0 1 Enable function 1
1 2 Enable function 2
2 4 Enable function 3
3 8 Enable function 4
4 16 Enable function 5
5 32 Enable function 6
6 64 Enable function 7
7 128 Enable function 8

In case the operator wants:

• To disable all functions the relevant parameter must be set to 0.

• To enable all functions the value to be set is the sum 1+2+4+8+16+32+64+128 =

255.

• To enable, for example, the functions 3, 4, 6 and 8 the value to be set is the sum
4+8+32+128 = 172 (where 4 is the value associated to the function 3; 8 to the function
4; 32 to the function 6; 128 to the function 8).

• Numerics: the value can be modified by pressing the ▲ and/or ▼ buttons, in order to
increase or decrease one unit from the most rightwards decimal digit (if you press the
above buttons together with SHIFT, the figure will be increased or decreased by ten
units at a time). The change is cyclical: increasing the maximum value will lead to the
minimum one and vice versa.

• Numerics selected in a pre-defined list (for example the number of phases of the
genset): as for the numeric parameters, considering that the ▲ and/or ▼ buttons allow
to pass to the following/previous value in the pre-defined list (pressing the above
buttons together with SHIFT, you go to the value ten units after/before the current
one).

• Numerics selected in a number-string couples list (e.g. the type of pressure

sensor): as the previous point.

• Time: as numerical parameters, with one exception: the controller manages the
increase/decrease maintaining valid values (example: increasing from “00.59”, the
value goes to “01.00” and not to “00.60”).

ATS115-ATS115Plus Technical Manual 59

 • Strings (e.g. telephone numbers): in this case the display shows also a cursor
indicating the currently selected character in the string. The ▲▼ buttons work on the
selected character (passing to the one after/before in the ASCII table or to the one 10
units before/after if pressing the above buttons plus SHIFT). The ◄► buttons allow
to select the character to be changed.

You can only set the ASCII characters from 32 (Space) to 127 (Escape). It is not
possible to set extended ASCII characters (over 127) and the control ones (from
zero to 31).

• Hexadecimal strings (e.g. output bitmaps): as for the string parameters, but the
selectable characters are only “0-9” and “A-F” (only capitals for the latter).

11.5.1.8 Set up limits

The operator has not to worry about checking that the set up value is acceptable for the
controller since it is not possible to set up not acceptable values.

This goes for individual parameters; however, it is possible to set two or more parameters in
incongruent or incompatible ways. It is up to the operator to prevent this from occurring.

11.5.1.9 Exit programming

There are three ways to exit programming mode:

• Press the EXIT button 'n' times to scroll back to the main menu, then press it again to
exit programming. The main menu will be displayed on the next access to
programming.

• Press and hold the ESC button for two seconds from any position will cause
instantaneous exit from programming. The next access will get you to the same point.

• Turn the operation mode of the controller into AUTO or MAN. The next access will get
you to the same point.

11.5.1.10 Loading default values

WARNING: This procedure permanently reloads all factory parameters according

to access rights.

Sometimes, it may be useful to reload parameters factory values. To do so, first access
programming, then press and hold the ACK/TEST and ESC/SHIFT buttons simultaneously for
five seconds. The reload of factory values will be confirmed by a message on the display.

Factory values are reloaded only for parameters for which you have granted access
rights.
11.5.2 Status information (S.xx)
In this mode, information on the system status is provided. You can scroll through pages using
the LEFT and RIGHT horizontal buttons.

11.5.2.1 S.01 STATUS

Page S.01 (STATUS) shows system status information. Part of this information is shown on
the top status bar. It contains:

• Breakers status (ACB closed, ACB and BCB opened, BCB closed etc.).

• Working mode of the controller (MAN, AUTO, etc.).

• Possible start inhibitions of the source/s configured as genset/s.

• Source A status (absent, low, high etc.) and type (mains/genset).

60 ATS115-ATS115Plus Technical Manual

 • Source B status (absent, low, high etc.) and type (mains/genset).

• Possible activation of the “Neutral Position” or the switch status (it signals the presence of
at least one inhibition to the active switch, whether it is connected to digital inputs or to
serial port, on at least one of the two sources).

Some of these data are shown together with an elapsing time; for example, during the wait for
the engine cooling down, the residual time is shown.

11.5.2.2 S.02 FAULTS

Page S.02 (FAULTS) is automatically shown in case a new fault arises. For every anomaly:

• A letter that identifies the type:

o “A”: alarm (block)

o “W”: warning

• A three digit numeric code that uniquely identifies the anomaly. This code flashes until
it is acknowledged pressing the “ACK” pushbutton.

• An alphanumeric description, which depends on the language currently selected and

which, in some cases, can be customized using the controller parameters.

Each fault uses one or two rows of the LCD display. The fault shown in the highest position is
the most chronologically recent. If the space available is not enough to display all the faults,
only the most recent ones will be displayed. In order to see the others, it is required to:

• Press the ENTER key

• Use the ▲▼ keys to scroll the anomalies

• Press EXIT to leave the mode

11.5.2.3 S.03 SERIAL COMMUNICATION

Page S.03 (SERIAL COMMUNICATION) is dedicated to the status of the serial
communication to the serial ports. In case of functional problems, please check the content of
this page.

Received communication error counters are displayed. If the condition causing the malfunction
has been removed, you can reset the error counters on this page. To activate the error reset
function, press the ACK/ENTER button and scroll with the UP and DOWN buttons for the
errors to be reset. Hold down ACK/ENTER + ESC/SHIFT for a few seconds until the message
“RESET/DEFAULT” is displayed. To exit the error selection, use the ESC/SHIFT button.

The type of connection (direct, via modem, via GSM) and the related status (on standby,
communicating etc.) are always displayed. In case of the GSM modem, the information related
to the radio signal strength and the provider is shown too.

11.5.2.4 S.04 ETHERNET

Page S.04 (ETHERNET) is dedicated to the status of the connection and of the communication
via Ethernet. It displays the addresses currently used on the controller and the MAC address
associated. In case of working problems, check the information in this page.

The possible statuses related to the communication via Ethernet are:

- On standby: no communication and Ethernet cable disconnected;

- On standby-connected: no communication and cable connected to the Ethernet network;

- Communicating: communication and cable connected to the Ethernet network.

▪ The code of the software currently loaded on the controller board (see par. 1.8)

11.5.2.6 S.06-07-08 GENERAL STATUS

Digital inputs can be configured as “generic status” using the following functions:

• “DIF.3201” and “DIF.3202”: displayed page S.06.

• “DIF.3203” and “DIF.3204”: displayed at page S.07.

• “DIF.3205” and “DIF.3206”: displayed at page S.08.

In this way, you can acquire and visualize the statuses that do not strictly depend on the logic
of the controller and that do not refer to warnings or arrests.

The pages are automatically (and individually) hided if there aren’t inputs configured with the
previous functions.

When an input configured with the functions “DIF.3202”, “DIF.3204” and “DIF.3206” (important
status) is activated, the controller forces the related page on the display, so that the operator
see immediately what happened.

Each configured input uses a line on the display: the controller displays the text configured for
that input (P.2003 for the input 1) followed by the status of the input (1/0). If the available space
is not enough to visualize all statuses, the controller shows them making the pages rotate

62 ATS115-ATS115Plus Technical Manual

 every two seconds; holding the SHIFT button down, the pages rotation is locked on the one
currently displayed.

The operator can divide these statuses in three pages (gathering them according to their
functions in order to avoid to have too many of them per page), using different functions for
the digital inputs.

11.5.2.7 S.09 DIGITAL INPUTS

Page S.09 (DIGITAL INPUTS) displays the status of the digital inputs of the controller. Both
physical and virtual inputs (16) are displayed.

The status of the inputs can be displayed in three different ways, which can be selected
pressing the ENTER button:

• Visualization of the inputs logic statuses (which can differ from the physical status if
some reversals are set with the parameters P.2000 and P.2050). Input statuses are
displayed normally (not in “reverse”). For each active input a “1” is displayed; for each
inactive input a “0” is displayed.

• Visualization of the inputs physical statuses. Statuses are displayed in “reverse”. For
each active input a “1” is displayed; for each inactive input a “0” is displayed. Physical
statuses do not have sense for virtual digital inputs.

• Visualization per function. Each line of the display shows one of the functions
associated to the inputs, followed by the input (logic) status that uses this function.
This is useful to check the status of a particular function without previously knowing
which input is using it. For example, it is possible to check immediately the ACB status
without knowing which input receives its feedback. If the lines on the display are not
enough to show all the configured functions, the controller shows them making the
pages rotate every two seconds; holding the SHIFT button down, the pages rotation
is locked on the one currently displayed.

11.5.2.8 S.10 DIGITAL OUTPUTS

Page S.10 (DIGITAL OUTPUTS) shows the status of all the digital outputs of the controller.

The status of the outputs can be displayed in three different ways, which can be selected
pressing the ENTER button:

• Visualization of the outputs logic statuses (which can differ from the physical status if
some reversals are set with the parameters P.3000 and P.3020). Input statuses are
displayed normally (not in “reverse”). For each active input a “1” is displayed; for each
inactive input a “0” is displayed.

• Visualization of the outputs physical statuses. Statuses are displayed in “reverse”. For
each active input a “1” is displayed; for each inactive input a “0” is displayed.

• Visualization per function. Each line of the display shows one of the functions
associated to the outputs, followed by the outputs (logic) status that uses this function.
This is useful to check the status of a particular function without previously knowing
which output is using it. For example, it is possible to check immediately the ACB
status without knowing which output receives its feedback. If the lines on the display
are not enough to show all the configured functions, the controller shows them making
the pages rotate every two seconds; holding the SHIFT button down, the pages
rotation is locked on the one currently displayed.

11.5.2.9 S.11 ANALOGUE INPUTS

Page S.11 (ANALOGUE INPUTS) shows the value of the analogue inputs Ai1, Ai2, Ai3 of the
controller (the JM connector), of the emergency stop (EM-S) and of the fourth analogue input
Ai4 (JL_4). For each input the measure is displayed in Volt, for terminals JM-2, JM-3 and JM-
4 the measure is displayed in Ohm too.

ATS115-ATS115Plus Technical Manual 63

 11.5.3 Electrical measurement (M.xx)
This mode displays all the information on the controller measurements on the electric lines.
You can scroll through pages using the LEFT and RIGHT buttons.

11.5.3.1 M.01 SYSTEM

Page M.01 (SYSTEM) displays a wiring diagram of the system, showing:

▪ The mains. The symbol of the mains is solid if the mains is within the tolerance range,
flashing if the mains is missing or if it exceeds the tolerance range.

▪ The generator. The symbol of the generator is in “reverse” if the generator is powered.

▪ The loads. The symbol of the loads is displayed in “reverse” if the loads are powered
by the Source A or B.

▪ The ACB and BCB breakers. The symbol of the breaker shows:

o The open/closed status.

o The difference between status and breaker command (in this case the two contact
points of the breaker flash).

o The possibility of using the synchronization to close the breaker if the

synchronization can be used, the two contact points of the breaker are empty
squares, otherwise they are full squares).

▪ The power flows are displayed with arrows in the three branches of the system. The arrow
points in the direction of the power. It flashes (to indicate a faulty situation) in case of
reversed power on the generator and in case of negative power to the loads.

▪ The active power and the power factor measurements.

▪ A flashing little square next to the Source A or B to indicate which is the priority source at
the moment.

11.5.3.2 M.02 SOURCE A

This page shows the phase-phase concatenated voltages and the frequency of the Source A
(configurable as mains or genset), in addition to the rotation direction of the phases (clockwise
or counter clockwise). For three-phase systems, the concatenated voltages are displayed; for
the one-phase systems, the single phase voltage is displayed (the others are replaced by
dashes) and the rotation direction is not displayed.

To the bottom right there is an icon that allows the immediate identification of the fact that the
page is related to the MAINS or the GENSET measures, according to the setting of the
parameter P.0100 – “Source A”.

11.5.3.3 M.03 SOURCE A (second page)

This page shows the phase phase-neutral voltages and the frequency of the Source A
(configurable as mains or genset), in addition to the rotation direction of the phases (clockwise
or counter clockwise). For three-phase systems, the concatenated voltages are displayed; for
the one-phase systems, the single phase voltage is displayed (the others are replaced by
dashes) and the rotation direction is not displayed.

To the bottom right there is an icon that allows the immediate identification of the fact that the
page is related to the MAINS or the GENSET measures, according to the setting of the
parameter P.0100 – “Source A”.

The page only exists if the system is set to use the neutral connection on SOURCE A. (see
par. 8.1).

64 ATS115-ATS115Plus Technical Manual

11.5.3.4 M.04 SOURCE B
This page shows the phase-phase concatenated voltages and the frequency of the Source B
(configurable as mains or genset), in addition to the rotation direction of the phases (clockwise
or counter clockwise). For three-phase systems, the concatenated voltages are displayed; for
the one-phase systems, the single phase voltage is displayed (the others are replaced by
dashes) and the rotation direction is not displayed.

To the bottom right there is an icon that allows the immediate identification of the fact that the
page is related to the MAINS or the GENSET measures, according to the setting of the
parameter P.0200 – “Source B”.

11.5.3.5 M.05 SOURCE B (second page)

This page shows the phase phase-neutral voltages and the frequency of the Source B
(configurable as mains or genset), in addition to the rotation direction of the phases (clockwise
or counter clockwise). For three-phase systems, the concatenated voltages are displayed; for
the one-phase systems, the single phase voltage is displayed (the others are replaced by
dashes) and the rotation direction is not displayed.

To the bottom right there is an icon that allows the immediate identification of the fact that the
page is related to the MAINS or the GENSET measures, according to the setting of the
parameter P.0200 – “Source B”.

The page only exists if the system is set to use the neutral connection on SOURCE B. (see
par. 8.1).

11.5.3.6 M.06 CURRENTS

This window displays the three phase currents measured by the controller (for single-phase
systems the second and the third are replaced by dashes). It is possible to specify where to
measure the current, according to the way in which the CTs have been installed on the plant.

To the bottom right each time a letter A or B is displayed in order to specify the real
source on which the currents are measured, together with the related symbol of the
mains or the genset properly set (P.0100 or P.0200 respectively for the Source A or B).

Using the P.0303 parameter – “C.T. Connection”:

• 0 - “On Source A”: the CTs are installed on the ACB breaker. The currents measured
are the ones supplied by the Source A. At the right bottom corner the letter A and the
mains or genset symbol, according to the value set in P.0100 parameter, are
displayed.

• 1 - “On Source A”: the CTs are installed on the BCB breaker. The currents measured
are the ones supplied by the Source B. At the right bottom corner the letter B and the
mains or genset symbol, according to the value set in P.0200 parameter, are
displayed.

• 2 - “On Loads”: the CTs are installed on the Loads lines (downline the ACB/BCB
breakers). The currents measured are the ones supplied by the Source A if the ACB
is closed, or by the Source B if the BCB is closed. In case the ACB breaker is closed,
at the right bottom corner the letter A and the mains or genset symbol, according to
the value set in P.0100 parameter, are displayed. Instead, if the BCB breaker is
closed, the letter B and the mains or genset symbol, according to the value set in
P.0200 parameter, are displayed.

• The currents are measured if the primary and secondary CTs values are not set to
zero (respectively in the parameters P.0302 – “C.T. Primary Source/Load” and P.0310
– “C.T. Secondary Source/Load”).

ATS115-ATS115Plus Technical Manual 65

 If the ATS115 has been configured correctly, it is possible to measure the negative-sequence
current, the auxiliary current, the neutral current and the differential current. Consequently,
they will be displayed on the right side of the screen, identified by the following symbols:

▪ I− : negative-sequence current.

▪ Ax : auxiliary current.

▪ An : neutral current.

▪ A∑ : differential current.

The neutral and differential current are displayed only when the measure is available, or if the
P.0314 parameter (Usage of auxiliary current) has been set to “2 - Neutral”, if the CTs of the
auxiliary current have the same report of the primary and the secondary and if the CTs are
connected to the same line (both on the generator or on the loads, or if the loads are supplied
with power from the genset).

The auxiliary current is displayed only if the P.0314 parameter (Usage of auxiliary current) has
been set to a value different from “0 - Not used”.

The page only exists if the primary and the secondary CTs values for the phase current and
for the auxiliary current are set to a value different from zero (respectively in the parameters
P.0302 – “C.T. Primary Source/Load” and P.0310 – “C.T. Secondary Source/Load”, P.0311 –
“Primary of C.T. for auxiliary current” and P.0312 – “Secondary of C.T. for auxiliary current”).

11.5.3.7 M.07 POWERS 1

This page shows the active powers (kW), the power factors and the loading types on single or
total phases (for single-phase systems, the information related to phases 2 and 3 are replaced
by dashes). At the right bottom corner the Source (A or B) together with its related icon (genset
or mains) are displayed, in order to indicate which are the powers under consideration (see
note in 11.5.3.7).

The powers, the power factors and the loading types are not measured if the C.T. value is set
to zero in the parameter P.0302 – “C.T. Primary Source/Load”.

11.5.3.8 M.08 POWERS 2

This page shows the reactive powers (kvar) and the apparent powers (kVA) on single or total
phases (for single-phase systems, the information related to phases 2 and 3 are replaced by
dashes). At the right bottom corner the Source (A or B) together with its related icon (genset
or mains) are displayed, in order to indicate which are the powers under consideration (see
note in 11.5.3.7).

The powers are not measured if the C.T. value is set to zero in the parameter P.0302 – “C.T.
Primary Source/Load”.

11.5.3.9 M.09 COUNTERS A

This page shows the active and reactive power counters (partial and total) and the working
hours (partial and total) counted by the controller relating to the Source A, that is when the
loads are connected to the Source A.

The active power is counted only if positive (it is not counted in case of reversed power). The
reactive power is counted in module (the counter goes up both with capacitive loads and
inductive loads).

On this page you can reset to zero the partial counters individually. To this purpose, it is
necessary to:

• Press ENTER: one of the counters will be highlighted.

• Use the vertical scrolling buttons UP and DOWN to select the counter to reset to zero.

• Press and hold the ENTER and EXIT buttons for five seconds.

66 ATS115-ATS115Plus Technical Manual

 • Press the EXIT key.

11.5.3.10 M.10 COUNTERS B

This page shows the active and reactive power counters (partial and total) and the working
hours (partial and total) counted by the controller relating to the Source B, that is when the
loads are connected to the Source B.

The active power is counted only if positive (it is not counted in case of reversed power). The
reactive power is counted in module (the counter goes up both with capacitive loads and
inductive loads).

On this page you can reset to zero the partial counters individually. To this purpose, it is
necessary to:

• Press ENTER: one of the counters will be highlighted.

• Use the vertical scrolling buttons UP and DOWN to select the counter to reset to zero.

• Press and hold the ENTER and EXIT buttons for five seconds.

• Press the EXIT key.

11.5.3.11 M.11-12-13 EXTERNAL MEASUREMENTS

The analogue inputs can be configured as “generic measurements” using the following
functions:

• “AIF.2001”: in this case they are displayed at page M.11.

• “AIF.2003”: in this case they are displayed at page M.12.

• “AIF.2005”: in this case they are displayed at page M.13.

In this way, the operator can display the measures that do not concern the operating logic of
the controller directly, gathering them on more pages according to their logic function, not to
have too many measures on the same page.

The pages are automatically (and individually) hided if there are not inputs configured with the
previous functions.

Each configured input uses a line on the display: the controller displays the text configured for
that input, followed by the measure acquired (and eventually converted) by the input itself. In
case of setting a unite of measure in the conversion curve, this will be displayed too. If the
available space is not enough to display all the measures, the controller will show them making
a two-second rotation; by holding down the SHIFT button, the rotation will be locked on the
ones currently displayed.

11.5.4 History Logs (H.xx)

When in operation, except for the OFF/RESET mode, the controller performs periodical or on-
event recordings that can be partially configured with programming parameters.

The controller manages three types of archive:

1. Events

2. Fast analogues

3. Slow analogues

The history logs can be accessed in any controller working status. To access the archive
visualization, press the ▲ and ▼ buttons until the HISTORY LOGS (H.01) page is displayed.

ATS115-ATS115Plus Technical Manual 67

 When in a mode limiting the use of vertical scroll buttons, you may require to press
repeatedly the ESC button.

By pressing ESC/SHIFT while on the main page of the HISTORY LOGS mode, the upper
status bar will display a status message related to the engine sequence, while the last line of
the display will show the following message:
ENTER: visual.log

Then press ENTER to enable the mode (moving to page “H.03”).

At the start of the procedure, the menu of the various archives functions is displayed.

11.5.4.1 Log selection

H.03 LOGS |
HISTORY LOGS 1/03

1 EVENTS
2 FAST ANALOGUES
3 SLOW ANALOGUES

The first line always shows the numerical indication of the selected function and the number
of functions in the menu. The following display lines are used in order to show the selectable
functions. The selected item is highlighted in reverse (REVERSE).
Use the ▲ and ▼ buttons to cyclically scroll the menu to the lower and to the upper index
items (i.e. pressing ▲ allows to go directly from the first item to the last one and vice versa).

Press ENTER to enable the selected function (the one highlighted in reverse); press the ESC
button to return to page “H.01”.

11.5.4.2 Events page

When the previously configured events occur, the controller adds a record in this archive. The
full capacity is 126 records. If the archive is full and a new event occurs, the less recent is
overwritten (so there are always the last 126 events stored). For each event, besides a
numerical code identifying it, it records the following data: date/time of the event, operating
mode of the controller, source A or B operating, ACB and BCB status in that moment. If the
event is a fault, the measures described for the analogue log are stored too. Configuring the
events to be recorded is possible with parameter P.0441.

For the visualization of each event, the controller uses at least three pages on the display: if
the event displayed is one of the 21 latest faults, the pages used become seven. The main
page has the following format:

H.09 HISTORY |
1 EVENTS 10/86

17/03/14 14:37:55 ►
EVENT Code 0024

W024 BCB not opened

The second line of each event page shows which event is currently displayed (10) and the
partial event stored (86). Once the total number of events available is reached, the partial
value will remain fixed at the limit value (126) up to a possible log resetting. The example
above shows the event 10 of the 86 stored (out of 126 available).

The fourth line of each event page displays the record date/time; on the right, it also displays
two arrows indicating the availability of further pages to the right or to the left of the present
page for the current event.

The lines from the fifth to the eighth show different information, depending on the selected
page:

▪ The first page displays the numeric code of the event (W024 in the example) and the
clear description of the event, in this case warning W (“W024 BCB not opened”).

ATS115-ATS115Plus Technical Manual 71

 ▪ The second page displays the statuses of the system when the event is recorded:
controller operating mode and sources A and B status.

▪ The third page displays the switch statuses (ACB and BCB) when the event is recorded.

▪ The fourth page displays all the analogue values related to mains when the event is
recorded:

Source A Hz (Source A frequency)

Source A V 12 (Source A L1-L2 phase-to-phase voltage)
Source A V 23* (Source A L2-L3 phase-to-phase voltage)
Source A V 31* (Source A L3-L1 phase-to-phase voltage)

▪ The fifth page displays all the analogue values related to mains when the event is
recorded:

Source B Hz (Source B frequency)

Source B V12 (Source B L1-L2 phase-to-phase voltage)
Source B V23* (Source B L2-L3 phase-to-phase voltage)
Source B V31* (Source B L3-L1 phase-to-phase voltage)

▪ The sixth page displays all the analogue values related to loads, that is currents and
powers, when the event is recorded:

A1 (L1 phase current)

A2* (L2 phase current)
A3* (L3 phase current)
kW T (Total active power of the system)
kvar T (Total reactive power of the system)

11.5.4.3 Pages for analogue measures

At a configurable recording frequency by means of the parameters P.0442 (seconds) and
P.0443 (minutes), the controller records the following analogue measures with engine on
and/or off:

▪ Source A phase-to-phase voltages and frequency.

▪ Source B phase-to-phase voltages and frequency.

▪ Currents.

▪ Active, reactive and apparent powers, power factor and type of total plant load.

▪ Starting battery voltage and analogue sensors.

72 ATS115-ATS115Plus Technical Manual

Each recording is associated with its date/time. The measures not acquired (because the
controller was not set to acquire them) are replaced by dashes.

To visualize all recordings, the controller uses four pages of the display. The main page has
the following format:

11.5.4.4 Fast analogue logs

The fast analogues are recorded at a configurable pace by means of the P.0442 parameter
(interval in seconds) and the default interval is 60 seconds. This archive provides a total
storage capability of 42 records that covers a half hour time. Every following record overwrites
the previous one. The controller records the analogue values described in par. 11.5.4.3.

11.5.4.5 Slow analogue logs

The slow analogues are recorded at a configurable pace by means of the P.0443 parameter
(interval in minutes) and the default interval is 30 minutes. This archive provides a total storage
capability of 64 records that covers a half hour time. Every following record overwrites the
previous one. The controller records the analogue values described in par. 11.5.4.3.

11.5.4.6 Locked recordings

Analogue and events recordings are temporarily OFF when the key switch is in
“OFF/RESET” mode.

When the records are locked, a lock appears on the second line, after the text “HISTORY
LOGS” in all the history log windows.
In this situation, the controller internal counters keep on decreasing the time left to the next
recording expiry.

When the operation mode shifts from “OFF/RESET” to “MAN” or “AUTO”, the controller checks
if some recording counters expired. If so, the recorded date and time of the status change are
stored; otherwise, the count continues till the next recording is stored.

Example:

Parameters are set for the event recording each 40 seconds.

Time/Date: 12:45 17/03/14 Switch from “MAN”/“AUTO” mode to “OFF/RESET” mode:

Recordings are “Locked”.

Time/Date: 13:10 17/03/14 Switch from “OFF/RESET” mode to “MAN/AUTO” mode.

25 seconds passed, the recording will be run in 15 seconds in analogue mode (40 seconds).

11.5.4.7 Exit logs visualization

There are two ways to exit the log visualization:

• Press the ESC button 'n' times to go back to page H.01.

• Change the operating mode of the controller.

In both cases, page H.01 will be displayed; move to other display modes using the ▲ and ▼
buttons.

11.5.4.8 Language selection
ATS115 allows to select the language to be used for all the text messages shown on the
multifunctional display. Currently, four languages are supported: Italian, English, French and
Russian (the default one is English).

At the page S.05 it is possible to select the desired language.

12.
12.1
ATS115 allows three operating modes:
• OFF_RESET: the gen-set is off (or in the arrest phase), the faults are all cancelled
and it is possible to access the programming to modify the parameters. The breakers
status depends on the plant setting; generally, the BCB breaker is open, while the
ACB breaker is closed, in order to connect the loads to mains.
• MAN: the genset power-up and the loads changeover on the source A or B have to
be performed by the operator (the controller does not perform these operations
automatically). As the protections are activated, the controller can perform them
automatically in case of need. The controller allows the access to programming, but
only some parameters can be changed.
• AUTO: the group start and stop and the ACB and BCB breakers management have
to be performed by the controller (the operator cannot intervene). All operations are
enabled. The controller allows the access to programming, but only some parameters
can be changed.
• TEST: this operation mode is nearly identical to AUTO. The only difference is that the
engine is anyway (automatically) started even with mains and/or automatic
intervention inhibition contact ON. The parameters P.0122 and P.0222 “Enabling test
loading”, allows indicating to the controller if it must automatically change-over the
loads to the generator (respectively on source A or B). When the controller goes back
to AUTO mode (when the test is finished), the loads are automatically changed-over
to the mains and the engine is stopped with normal procedure. The controller
automatically switches from TEST to AUTO in case existing conditions require an
automatic intervention by the genset. The operator is not allowed to manually operate
the ACB and BCB switches. Accessing programming is allowed, though only some
parameters can be modified.
• REMOTE START: nearly identical to AUTO. The only difference is that the engine is
anyway (automatically) started even with mains and/or automatic intervention
inhibition contact ON; the loads are changed-over to the generator. AUTO mode
supersedes TEST mode (i.e., it can interrupt or replace the periodic test). It is also
overriding with respect to the AUTO (once the remote start is activated, any request
for automatic intervention is ignored). The operator is not allowed to manually operate
the ACB and BCB switches. Accessing programming is allowed, though only some
parameters can be modified.

The operating mode can be selected in two different ways:

• Using the “MODE ▲” and “MODE ▼” buttons of the controller board. The buttons
must be pressed consecutively and held for at least half a second to force mode
change. The buttons are if at least one of the inputs described below exists and is
active.

• Using one or several inputs configured with the following functions:

▪ DIF.2271 “OFF/RESET by remote control”.

ATS115-ATS115Plus Technical Manual 75

 ▪ DIF.2272 “MAN by remote control”.
▪ DIF.2273 “AUTO by remote control”.
When one of these inputs is active, the controller operating mode is forced and it is no longer
possible to use the buttons on the panel, nor the controls of the serial ports to change it (the
first line of the display shows a key-shaped icon).
When none of these inputs is active, you are able to use the buttons and the serial ports
controls again to change the operating mode.
If there are multiple active inputs at the same time, the priority is given to the input that
forces the OFF/RESET mode, followed by the one that forces the MAN mode and
finally the one that forces the AUTO mode.
You don’t need to use all three inputs. For example, you can use a single input to force
the AUTO status: when the input is active the controller is always in AUTO mode, and
when it is deactivated, the controller remains in AUTO mode, but you can use the
buttons to change to MAN or to OFF/RESET.
If only one input is used to force the OFF/RESET mode, the controller acts
differently: when the input is active, the controller is always in OFF/RESET, and
when the input goes back to standby, the controller goes back to the mode
present before the input activation.

To activate the TEST mode, it is first of all necessary that the Controller is in AUTO, the source
is configured as “1- Generator” and that there are no requests of starting. To enable the TEST
mode, the controller is first set to AUTO without any automatic start request. All possible TEST
function activation modes are described below. The TEST mode is signalled by the flashing of
the AUTO indicator light on the panel (50% on – 50% off). You can shift to TEST mode by
properly configuring the following parameters:
- P.0418: Weekly test schedule on source A

- P.0419: Test start time source A

- P.0420: Test duration source A

- P.0438: Weekly test schedule on source B

- P.0439: Test start time source B

- P.0440: Test duration source B

These parameters allow for weekly programming of the time intervals for TEST mode
engine start (to keep it efficient). In this case, shifting to TEST mode automatically
occurs at set days and times. The controller returns to AUTO when the TEST time
interval ends.

To activate REMOTE START mode, instead, the controller must first of all be in AUTO or in
TEST mode. In addition, in case an input is configured with code DIF.2701 – “Enable remote
start request” in the parameters of any input, this input shall be active. You may shift to
REMOTE STARTUP in the following cases:
• Configuring a digital input of the controller to acquire the “Remote start request” with
code DIF.2032. When this input is active, the controller shifts to REMOTE STARTUP;
it deactivates when reverting to AUTO.
• By means of a proper command via SMS (refer to document [3]). In this case, the
controller shifts to REMOTE START as soon as it receives the SMS and returns to
AUTO when it receives the opposite command. In this case, you need to configure an
input for acquiring the contact enable remote startup request, code DIF2701, and the
input shall be active (normally wired on a panel for enabling remote commands).

76 ATS115-ATS115Plus Technical Manual

 • Using parameters P.0428, P.0429 and P.0430 it is possible to define on a weekly
basis hourly operation intervals when the genset shifts automatically to REMOTE
START. In particular, parameter P.0428 allows to set the week days in which this
function is active and the remaining two allow you to set an hour range valid for all
selected days. The range start time (P.0429) refers to the days set in P.0428, while
the range end time (P.0430) refers to the same day, if its value is higher than P.0428,
or to the following day if lower (across midnight). Moreover, setting P.0429 and P.0430
to the same value defines a full day's range.

In those plants configured with two generators, the remote starting might require the
starting of one of the two sources based on the following priority criteria:

▪ Work time band configured in parameters P.0425 and P.0426.

▪ Working hours configured in parameter P.0424.

▪ At least one configured input with digital function DIF.2121.

▪ Priority source configured in parameter P.0427.

▪ First generator available (normally generator A).

The “OFF/RESET”, “MAN” and “AUTO” lights state the current selected mode, while the
REMOTE START light indicates that the Controller has been started in automatic mode or
from remote.
The controller records each operating variation in the event log, if enabled with bit 0 of the
P.0441 parameter:

• EVT.1001: records the shift to OFF/RESET mode.

• EVT.1002: records the shift to MAN mode.

• EVT.1003: records the shift to AUTO mode.

• EVT.1004: records the shift to TEST mode.

• EVT.1005: records the shift to REMOTE START mode.

There are some functions for the digital outputs configuration related to the working modality:

• DOF.3001 - “OFF/RESET”. The controller is active when this output is in OFF/RESET

mode.

• DOF.3002 - “MAN”. The controller is active when this output is in MAN mode.

• DOF.3003 - “AUTO”. The controller is active when this output is in AUTO mode.

• DOF.3004 - “TEST”. The controller activates this output when it is in TEST mode.

• DOF.3005 - “Remote Start”. The controller activates this output when in

AVVIAMENTO REMOTO mode.

• DOF.3011 - “Not in OFF/RESET”. The controller activates this output when it is in

AUTO or MAN mode.

• DOF.3012 - “One of the automatic modes”. The output is activated when the controller
is in one of the automatic operation modes, that is AUTO, TEST or REMOTE START.
In addition, the controller makes its own operation mode available for the AND/OR logics by
means of the following internal statuses:

• ST.000 - “OFF/RESET”.

• ST.001 - “Manual”.

• ST.002 - “Automatic”.

ATS115-ATS115Plus Technical Manual 77

 • ST.003 - “Test”.

• ST.004 - “Remote start”.

12.2
The ATS115 controller has to know the status of the two sources A and B, basically because
it has to decide which of the two breakers ACB or BCB has to be closed.

Generally, ATS115 uses its three-phase sensors (JG and JH connectors) to measure and
manage the status of the two sources. If, for any reason, one or both controller sensors cannot
be used, they must be disabled setting to zero the parameter concerning the nominal voltage
(P.0102 for SOURCE A and P.0202 for SOURCE B).

Digital inputs (instead of or in addition to internal sensors) can be used as configured in the
following way:

• DIF.3101 – “Source A external sensor“.

• DIF.3102 – “Source B external sensor”.

Generally, a relay with alternating coil connected between two phases of the BUS is used: its
normally open contact connects the controller input to the supply negative, in order to activate
the relay and the input with the BUS working.

Using an input instead of the internal sensor (internal sensor disabled), the logic is as follows:

• Input active: voltage on source.

• Input inactive: no voltage on source.

Using an input in addition to the internal sensor (internal sensor enabled) instead, the controller
uses the input to decide if the source is operating, even if its internal sensor is not measuring
it (OR logic). In this case too, the input active shows the voltage presence.
12.2.1 Internal sensor
To connect SOURCE A and SOURCE B voltages see par. 7 and par. 0.

If the internal sensor can be used to acquire the frequency and voltage measures (JG and JH
connectors), there are different values which influence its management. The following table
shows the parameters concerning both sources. In the rest of the paragraph the SOURCE A
will be the one taken under consideration.

 To define the sources (SOURCE A and B) status, the controller can execute up to four different
controls, which can be individually disabled. Below they are described individually (also with
examples): remember that voltage and frequency controls cannot be both disabled (in this
case the source is always considered off).

12.2.1.1 Frequency control

To disable this control, it is enough to verify one of the following conditions:

• P.0108 = 0 %.

• P.0109 = 0 %

• P.0109 = 200%.

• P.0108 >= P.0109

Let’s make a practical example on the different threshold used, with the default values for the
parameters mentioned above.

Parameter Description Default value Frequency in Hz

P.0301 Nominal frequency 50 Hz 50.00

P.0108 Min. frequency threshold 90.0 % 45.00

P.0109 Max. frequency threshold 110.0 % 55.00

P.0110 Hysteresis measure 2.5 % 1.25

The hysteresis is calculated as the half of the difference between P.0109 and P.0108. It is
limited to the maximum value set with the parameter P.0110. The hysteresis is applied:

• Up to the minimum frequency threshold (between 45.00 Hz and 46.25 Hz).

• Down to the maximum frequency threshold (between 53.75 Hz and 55.00 Hz).

Considering these values the following segments are identified:

0.00 V .
Segment A: low
45.00 V .
Segment B: hysteresis
46.25 (45.00 + 1.25) V .
Segment C: in tolerance
53.75 (55.00 – 1.25) V .
Segment D: hysteresis
55.00 V .
Segment G: high
xxx V .

If the frequency is in the segments “B”, “D” it maintains the previous status (hysteresis). For
example, if the frequency was in the “C” segment and it is in the “D” segment, it is still
considered “In tolerance”. Instead, if it was in the “A” segment and now it is in the “B” segment,
it is considered “Low”. The frequency is considered “Off” only if the measurement is 0 Hz.

12.2.1.2 Voltages control

To disable this control, it is enough to verify one of the following conditions:

• P.0111 = 0 %.

• P.0112 = 0 %

ATS115-ATS115Plus Technical Manual 79

 • P.0112 = 200%.

• P.0111 >= P.0224

Let’s make a practical example on the different threshold used, with the default values for the
parameters mentioned above.

Parameter Description Default value Voltage in volt

P.0102 Nominal voltage 400 V 400
P.0106 Voltage threshold 20.0 % 80
P.0111 Min. voltage threshold 80.0 % 320
P.0112 Max. voltage threshold 110.0 % 440
P.0110 Hysteresis measures 2.5 % 10

P.0121 Thresholds to VLN 1 – Yes 2 – No

The hysteresis on the thresholds is calculated as the half of the difference between P.0112
and P.0111. It is limited to the maximum value set with the parameter P.0110. The hysteresis
is applied:

• Down to the voltage threshold (between 70 V and 80 V).

• Up to the minimum voltage threshold (between 320 V and 330 V).

• Down to the maximum voltage threshold (between 430 V and 440 V).

Considering these values the following segments are identified:

0 V .
Segment A: off
70 (80-10) V .
Segment B: hysteresis
80 V .
Segment C: low
320 V .
Segment D: hysteresis
330 (320+10) V .
Segment E: in tolerance
430 (440-10) V .
Segment F: hysteresis
440 V .
Segment G: high
xxx V .

If the voltage is in the segments “B”, “D”, “F” it maintains the previous status (hysteresis). For
example, if the voltage was in the “E” segment and it is in the “D” segment, it is still considered
“In tolerance”. Instead, if it was in the “C” segment and now it is in the “D” segment, it is
considered “Low”.

These statuses are managed at single-phase level.

Note: the parameter P.0121 / P.0221 performs the checks on thresholds and hysteresis also
on phase voltages (on phase-to-phase voltages they are always enabled).

12.2.1.3 Unbalance check

In three-phase systems, the source can be considered 'out of tolerance' in case the absolute
value of the three phase-to-phase voltages differs of a greater quantity than the threshold set.

To disable this check, simply set the parameter P.0113 and/or the parameter P.0213 to zero.

80 ATS115-ATS115Plus Technical Manual

 Here follows an example about the different thresholds used, including the default values for
said parameters:

SOURCE SOURCE Default Voltage

Description
A B value in volt
P.0102 P.0202 Nominal voltage 400 V 400

P.0113 P.0213 Voltage unbalance threshold 10.0 % 40

In this case, the two phase-to-phase voltages absolute value differs of more than 40 V, the
source is considered out of tolerance (the led flashes with 25% on). In case all phase-to-phase
voltages absolute values are lower than 40 V, the source is considered in tolerance. No
hysteresis is managed for this check.

12.2.1.4 Rotation direction check

In three-phase systems, the source can be considered 'out of tolerance' if the phases rotation
direction differs from the setting of the parameters P.0114 and/or P.0214 “Phase sequence
required”.

SOURCE SOURCE Default Voltage

Description
A B value in volt
P.0114 P.0214 Required phase sequence 0 – None 1 – Per hour

To disable this check, simply set the parameter P.0114 and/or the parameter P.0214 to zero.

In case a “clockwise” rotation direction is required, please set “1” in P.0114 and/or in P.0214;
in case the rotation direction is “counter-clockwise”, the source is considered “out of tolerance”
(the led flashes with 25% on).

In case a “counter-clockwise” rotation direction is required, please set “2” in P.0114 and/or
P.0214; in case the rotation direction is “clockwise”, the source is considered “out of tolerance”
(the led flashes with 25% on).

12.2.1.5 Internal sensor status

In order to diagnose the “global” status of the sources (SOURCE A and B), the following
algorithms are used, shown in their computing order:

• In case the status of all existing voltages (1 or 3) and the frequency are “Absent”, the
global status too is “Absent”.

• In case the status of all existing voltages (1 or 3) and the frequency are “In
tolerance”, the global status too is “In tolerance”.

• In case the status of at least one voltage or frequency is “High”, the global status too
is “High”.

• In case none of the previous conditions occurs, the global status is “Low”.

ATS115-ATS115Plus Technical Manual 81

 12.2.2 Global status of the sources (SOURCE A and B)
Whatever the method to acquire the instant status of the sources (SOURCE A and B) is for
the plant operating logics, the global status of the sources (SOURCE A and B), is described
in four phases:

SOURCE in
After the time set with tolerance
P.0115 / P.0215 SOURCE “out of tolerance”
(0,1 seconds if
not in AUTO)

Delay SOURCE “in tolerance”

SOURCE “in Delay
tolerance” SOURCE “out
of tolerance”
SOURCE “in tolerance”

SOURCE “out of tolerance” After the time set with

SOURCE
P.0116 / P.0216.
“out of
tolerance”

12.2.3 Events and communications

The controller records any change of the SOURCE A and SOURCE B status in the events
logs, if it is enabled with bit 1 and 2 of the P.0441 parameter:

• EVT.1010: Lack of voltage on SOURCE A.

• EVT.1011: Voltage on SOURCE A but “out of tolerance”.

• EVT.1012: Voltage on SOURCE A and “in tolerance”.

• EVT.1020: Lack of voltage on SOURCE B.

• EVT.1021: Voltage on SOURCE B but “out of tolerance”.

• EVT.1022: Voltage on SOURCE B and “in tolerance”.

There are some functions available for the configuration of the outputs related to the SOURCE
A and SOURCE B status:

• DOF.3032 - “SOURCE A in tolerance”. The controller activates this output when

voltages and frequency on SOURCE A are in tolerance from the time configured.

• DOF.3033 - “SOURCE B in tolerance”. The controller activates this output when

voltages and frequency on SOURCE B are in tolerance from the time configured.

• DOF.3034 - “Voltage on SOURCE A”. The controller activates this output when it
measures voltage (even if out of tolerance) on SOURCE A.

• DOF.3035 - “Voltage on SOURCE B”. The controller activates this output when it
measures voltage (even if out of tolerance) on SOURCE B.

Moreover, the controller makes the status of the SOURCE A and the SOURCE B available for
the AND/OR logics through the following internal statuses:

82 ATS115-ATS115Plus Technical Manual

 • ST.016 - "SOURCE A voltage/frequency present"

• ST.017 - "SOURCE A out of tolerance or absent"

• ST.018 - "SOURCE A delay in tolerance"

• ST.019 - "SOURCE A in tolerance"

• ST.020 - "SOURCE A delay out of tolerance or absent"

• ST.024 - "SOURCE B voltage/frequency present"

• ST.025 - "SOURCE B out of tolerance or absent"

• ST.026 - "SOURCE B delay in tolerance"

• ST.027 - "SOURCE B in tolerance"

• ST.028 - "SOURCE B delay out of tolerance or absent"

12.3
ATS115 controller does not manage the engine power-up sequence, but make an output
available to require its intervention for each source. After that, it lies in wait for the normal
genset conditions, supervising its voltage and frequency. Once receiving this input command,
the external control unit will start the engine control sequence. If the normal genset conditions
are not reached by the time set in the parameter P.0115/P.0215 – “Presence delay Source
A/B” the warning W007 / W008 – “Source A/B lack of normal conditions” will come out. Press
ACK to acknowledge the warning.

Similarly, in order to stop the genset, ATS115 controller does not manage the engine stop, but
simply remove the output and wait for the voltage absence of the genset side. It is possible to
delay the deactivation of this output through the parameter P.0119/P.0219 – “Delay before
stop Source A/B” (no delay is set by default). The external control unit, which no longer
receives this input command, will start the engine stop sequence. If the engine stop is not
revealed (frequency voltage absence) by the time set in the parameter P.0118/P.0218 – “Stop
cycle duration Source A/B” the warning W021 / W022 – “Source A/B stop failure” will come
out. Press ACK to acknowledge the warning.

The two digital outputs to require the start and stop of the sources A and B (associated to
relays 5 and 6 by default) are configurable setting the output function DOF.1001 – “Source A
start command” and DOF.1002 – “Source B start command”.

The manual and automatic start sequences and engine start command outputs are managed
only if the source is set as genset (value 1 in parameters P.0100 and P.0200).

In MAN, the keys “SOURCE A 0/1” and “SOURCE B 0/1” on the front panel of the
controller act as “toggle” on the output set with the function DOF.1001 – “A start command”
and DOF.1002 – “B start command” (activating and deactivating them at each key pressing).
In case of error, the start command is removed. In order to repeat it again and to acknowledge
the warning, press the ACK button and the key related to the source required.

12.4
In AUTO mode, the automatic start of the source/s set as genset can be inhibited anyway by
two causes:
• Operating time bands.
• Digital input.

When there is an inhibition active, a flashing lock is displayed in the top right corner of the
display.

ATS115-ATS115Plus Technical Manual 83

 12.4.1 Contact inhibition
The controller can use a digital input programmed for inhibiting the genset automatic operation
(function DIF.2501 – “Genset operating inhibition”). If the input is “active”, the engine is never
automatically started, not even if the plants condition require it.

Using the parameter P.0357 it is possible to set a delay between the input physical activation
and this function logic activation: that delay can only be applied to a controller in AUTO mode,
otherwise the delay is null.

Using the parameter P.0358 it is possible to set a delay between the input physical deactivation
and this function logic deactivation: in case the genset is already running, the delay is reduced
two seconds (firm).

When a function with value DIF.2501 is coupled with a digital input, the acquisition of
this input depends on the time set in P.0357 and/or in P.0358; the acquisition time
related to the digital input is ignored.
The controller also makes available, for the use of AND/OR logics, the internal status ST.080
- "Contact starting inhibition”.
The controller records any change of the inhibition status in the events log, if it is enabled with
bit 6 of the P.0441 parameter:

• EVT.1013: Inhibition activated (from configurable input)

• EVT.1014 Inhibition not activated (from configurable input)

12.4.2 Clock inhibition

Using parameters P.0421, P.0422 and P.0423, it is possible to define weekly hour operation
ranges, in which the genset is enabled to work. In particular, the parameter P.0421 allows to
set the genset weekly operation days. The remaining two allow to set an hour range valid for
all selected days. The range start time (P.0422) refers to the days set in P.0421, while the
range end time (P.0423) refers to the same day, if its value is higher than P.0422, or to the
following day if lower (across midnight). Moreover, setting P.0422 and P.0423 to the same
value a full day range is set.
The controller also makes available, for the use of AND/OR logics, the internal status ST.081
- "Clock/Calendar starting inhibition”.

12.5
12.5.1 Digital outputs
There are four different command for the ACB breaker management:

• DOF.2001 - “ACB (NC) Undervoltage coil”. This function can be used to supply the
breaker under voltage coil (if any). The controller disables this output when it wants to
open the breaker; it enables it when it wants to close the breaker: the real closing
command will be activated at least 0.5 seconds after the activation of this output.

• DOF.2002 - “ACB Opening coil”. The controller enables this output when it wants to
open the breaker: the output goes back on standby once the breaker feedback shows
that it is open (or when the opening time-out expires).

• DOF.2003 - “ACB Closing coil”. The controller enables this output when it wants to
close the breaker (ensuring that the function DOF.2001 «if available» has been active
for at least 0.5 seconds): the output goes back on standby once the breaker shows
that it is closed (or when the closing time-out expires, or if the synchronism condition
is no longer met).

84 ATS115-ATS115Plus Technical Manual

 • DOF.2004 - “ACB steady opening command”. The controller enables this output when
it wants to open the breaker (ensuring that the function DOF.2001 «if available» has
been active for at least 0.5 seconds): the output stays active even if the breaker is
closed. The controller disables this function when it wants to open the breaker: the
output stays open even if the breaker is open. Use this output with remote control
switches, not with the motorized breakers.

Four different commands can be used to manage BCB breakers:

• DOF.2031 - “BCB (NC) Undervoltage coil”. This function can be used to supply the
breaker under voltage coil (if any). The controller disables this output when it wants to
open the breaker; it enables it when it wants to close the breaker: the real closing
command will be activated at least 0.5 seconds after the activation of this output.

• DOF.2032 - “BCB Opening coil”. The controller enables this output when it wants to
open the breaker: the output goes back on standby once the breaker feedback shows
that it is open (or when the opening time-out expires).

• DOF.2033 - “BCB Closing coil”. The controller enables this output when it wants to
close the breaker (ensuring that the function DOF.2031 «if available» has been active
for at least 0.5 seconds): the output goes back on standby once the breaker shows
that it is closed (or when the closing time-out expires, or if the synchronism condition
is no longer met).

• DOF.2034 - “BCB steady opening command”. The controller enables this output when
it wants to open the breaker (ensuring that the function DOF.2031 «if available» has
been active for at least 0.5 seconds): the output stays active even if the breaker is
closed. The controller disables this function when it wants to open the breaker: the
output stays open even if the breaker is open. Use this output with remote control
switches, not with the motorized breakers.
12.5.2 Digital inputs
The controller digital inputs can be used for different purposes, for the loads switch
management.

12.5.2.1 Acquiring breakers status

The features of inputs DIF.3001 - “ACB breaker status” and DIF.3002 - “BCB breaker status”
are used by the controller to acquire the feedback connection input, respectively of breakers
ACB and BCB. The controller uses these inputs for:

• Issuing failed opening or failed closing warnings.

• Its own operating sequence.

• Detecting the breakers status when it is remotely controlled.

• Displaying the breakers status on the front panel LEDs.

The delay associated to the input is used as maximum time for opening or closing the breaker.
Generally, the controller performs automatically three breaker opening and/or closing attempts
before signalling the warning of breaker opening and/or closing failure.

In theory, the controller could work even without this feedback. In this case, the controller
considers the breaker as closed once the closing command is issued; it considers it as open
once the opening command is issued. Actually, it is always better to connect the feedback.

In case the source A is set as mains, by means of the P.0304 parameter it is possible to specify
if the ACB breaker is supplied by the mains voltage. Therefore, in lack of mains, ACB opens
but the controller does not activate the related warning of ACB closing failure.

In case the source B is set as mains, by means of the P.0304 parameter it is possible to specify
if the BCB breaker is supplied by the mains voltage. Therefore, in lack of mains, BCB opens
but the controller does not activate the related warning of BCB closing failure.

ATS115-ATS115Plus Technical Manual 85

 12.5.3 OFF/RESET logic management
In OFF/RESET mode, both ACB and BCB are in standby (meanwhile, “ACB Under voltage
coin enabling” and “BCB Under voltage enabling” are in standby too). According to the
configuration of the plant, the breakers work in different ways:

• Plant with one genset and one mains, the breaker related to the mains source is
closed, while the one related to the genset is opened (i.e. P.0100 set to 0 - Mains and
P.0200 set to 1 - Genset: ACB is closed while BCB is opened).

• Plant with two gensets (P.0100 and P.0200 set to 1 - Genset), both breakers ACB and
BCB are opened.

• Plant with two gensets and two mains (P.0100 and P.0200 set to 0 - Mains), ACB
breaker is closed, while BCB is opened.
12.5.4 MAN logic management
ACB and BCB commands are activated only if all the following conditions are checked:

▪ If the source (SOURCE A or B) voltage and frequency have been in tolerance for a
proper time.

▪ If there are not stops or deactivations.

▪ If there are not forcing or digital input fails.

Generally, in MAN mode the loads are switched on the source set as mains, or are not supplied
in case of two gensets. The operator can decide which breaker must be opened or closed and
it interacts with the controller with manual opening and closing commands.

Two types of commands are provided:

• Using the controller keys

The keyboard has two separated keys for the opening and closing of the ACB and
BCB breakers. After starting the engine manually, the possibilities are:

▪ Pressing the ACB button with BCB closed and ACB opened, the controller
opens the BCB breaker and consequently close the ACB breaker (with Source
A present and in tolerance).

▪ Pressing the ACB button with BCB opened, the controller alternatively opens
and closes the ACB breaker.

▪ Pressing the BCB button with ACB closed and BCB opened, the controller
opens the ACB breaker and consequently close the BCB breaker (with Source
B present and in tolerance).

▪ Pressing the BCB button with ACB opened, the controller alternatively opens
and closes the BCB breaker.

If the genset engine of the source/s has not been activated manually, but its voltages
and frequencies are in tolerance, the controller allows the breakers opening/closing
anyway.

If using a switch, both ACB and BCB buttons work in the same way switching the loads
between the sources alternatively.

• Using the digital inputs of the controller (to connect external buttons that allow to
open/close the breakers manually). See below the functions available:
▪ Function DIF.1001 – “ACB Manual closing request”.
▪ Function DIF.1002 – “ACB Manual opening request”.
▪ Function DIF.1003 – “BCB Manual closing request”.

86 ATS115-ATS115Plus Technical Manual

 ▪ Function DIF.1004 – “BCB Manual opening request”.
These functions are accepted only if the controller is in MAN mode.
All these commands work on the “not active” to “active” pass of the input, not on the
steady “active” status.
Each breaker can use either commands or just the closing one. Using the only closing
command, it works as “toggle”: it manages the breaker opening when closed and the
breaker closing when open.
The use of both commands associated to two different inputs allows the switch
between sources. Indeed, the input with the function DIF.1001 can be used only when
the loads are connected to the source A; the input with the function DIF.1001 can be
used only when the loads are connected to the source B.

• Using the commands received from the serial ports. You need to write in sequence (within
5 seconds) in order to send the commands:
▪ HOLDING REGISTER 101: write the password configured with parameter
P.0004.
▪ HOLDING REGISTER 102:
▪ “31” to open ACB.
▪ “33” to close ACB.
▪ “41” to open BCB.
▪ “43” to close BCB.
12.5.5 AUTO logic management
ACB and BCB commands are activated only if all the following conditions are checked:

▪ If the source (SOURCE A or B) voltage and frequency have been in tolerance for a
proper time.

▪ If there are not stops or deactivations.

▪ If there are not forcing or digital input fails.

In AUTO mode, loads are switched on the first source available, according to the plant
configuration and the conditions above. Loads are switched on the other source only when the
source is out of tolerance. The switch uses a further timing in case of source set as genset: to
manage the breaker closing, the time P.0117 or P.0217 “Delay before supply“ must be passed
since the group power-up, that is since the genset measures are out of tolerance.

More details on the automatic switch sequence at par. 12.6.

12.5.6 Power switch management
Usually, for the power switch management, the ACB and MCB outputs of the JI connector are
used, that is two relays with potential-free change-over contacts. The clamps 1, 2, 3 of this
connector are related to the breaker for closing the loads on the source B (BCB), the others
clamps 4, 5, 6 for closing the loads on the source A (ACB). It is possible to set the controller
to command two separated breakers or a switch.

▪ Separated breakers. You need to set the parameter P.0306 (Contactors swap delay)
to a proper value. This parameter shows the minimum time between one breaker
opening and the other one closing. It is possible to use two outputs for the breakers
under voltage coils: the two functions are DOF.2001 – “ACB (NC) Undervoltage coil”
and DOF.2031 – “BCB Under voltage coil”. These outputs are associated to the
management logics that depend on the plant configuration used.
ATS115 uses logics that avoid the non-synchronized simultaneous closing of ACB
and BCB; anyway a wired external logic used for this purpose is necessary.

▪ Switch. You need to set the parameter P.0306 (Contactors swap delay) to zero,
avoiding a useless wait for the sources changeover. Moreover, it is possible to set in

ATS115-ATS115Plus Technical Manual 87

 P.0307 (Contactors holding time): it won’t be possible (neither manually nor
automatically) to invert the switch command if the time in P.0307 (Contactors holding
time) has not passed from the previous command. That is useful, because inverting
the command to some types of switches during the operating phase (before the switch
is complete) they may get locked, requiring a manual operation for the unlocking.

The LEDs on the panel, called ACB and BCB, turn on when the related breaker is closed; they
turn off when it is open. In particular:

▪ LED on: the breaker is closed.

▪ LED off: the breaker is open.

▪ LED flashing (on for 25% of time): the controller ordered the breaker closing, but it is open.

▪ LED flashing (on for 75% of time): the controller ordered the breaker closing, but it is
closed.

Moreover, setting a time different from zero to the inputs connected to the breakers status
(parameters P.2001…), the controller activates a warning if the command and the status of
each breaker keep on conflicting for that time. By the way, it is possible to connect also the
status of one of the breakers (in case of need): the signalisation of conflicting command/status
and the possible warnings will be managed only for that breaker.
12.5.7 Inhibition to automatic supply of the source (genset)
In all the automatic operation modes of the controller, the source circuit breaker configured as
genset (ACB or GCB or both) can be forced to open for different causes, even if the plant logic
requires its closing. This allows the use in plants where there can be more gensets in parallel
on the busbar and the controller has to close only when the plant manages to supply the load.
Please find below a description of these causes:
▪ It is possible to use a digital input configured with the function DIF.2503 – “Source A
inhibited to take the Load”. When this input is activated, the controller commands the
opening of ACB.

• It is possible to use a digital input configured with the function DIF.2504 – “Source B
inhibited to take the Load”. When this input is activated, the controller commands the
opening of BCB.

• It is possible to use a serial port command. This command is temporary (it lasts 30
seconds): it has to be continuously confirmed if you want to keep the ACB and/or BCB
open. You need to write in sequence (within 5 seconds) in order to send the commands:

• HOLDING REGISTER 101: write the password configured with parameter P.0004.

• HOLDING REGISTER 102:

▪ “31” to inhibit the automatic supply on source A (forced ACB open).
▪ “33” to remove the inhibition to the automatic supply on source A.
▪ “41” to inhibit the automatic supply on source B (forced BCB open).
▪ “43” to remove the inhibition to the automatic supply on source B.
The controller records any variation of the switch inhibition status in the history log, if it
has been enabled by bit 3 and 4 of parameter P.0441:

▪ EVT.1084 - " Switch on source A inhibited"

▪ EVT.1085 - " Switch on source A non-inhibited "

▪ EVT.1086 - " Switch on source B inhibited "

▪ EVT.1087 - " Switch on source B non-inhibited "

88 ATS115-ATS115Plus Technical Manual

12.5.8 Events and signalisation
The controller records any variation of the command and the status of the ACB breaker in the
history log, if enabled by the bit 3 and 4 of the P.0441 parameter:

• EVT.1030: ACB closing command.

• EVT.1031: ACB opening command.

• EVT.1032: ACB closed.

• EVT.1033: ACB open.

The controller records any variation of the command and the status of the BCB breaker in the
history log, if enabled by the bit 3 and 4 of the P.0441 parameter:

• EVT.1035: BCB closing command.

• EVT.1036: BCB opening command.

• EVT.1037: BCB closed.

• EVT.1038: BCB open.

The controller makes available the ACB commands and status, for the AND/OR logics, with
the following internal status:

• ST.064 - "ACB status"

• ST.068 - "ACB steady closing command"

The controller makes available the ACB commands and status, for the AND/OR logics, with
the following internal status:

• ST.065 - "BCB status"

• ST.069 - "BCB steady closing command "

12.6
In AUTO mode and depending on the plant configuration, the switch sequence between
sources follows slightly different logics. The external events that affects the operating logic are
not only connected to the source presence/absence (measured by voltage, frequency or
external sensor), but also to the working hours configuration (see par. 14.2) and to the
following functions related to digital inputs.

• DIF.2281 – “Switch on source A”.

• DIF.2282 – “Switch on source B”.

• DIF.4203 – “Source A fault”.

• DIF.4204 – “Source B fault”.

It is also possible to force the use of one source by the commands received from the serial
ports. Write in sequence (within 5 seconds) in order to send the commands:
▪ HOLDING REGISTER 101: write the password configure with parameter
P.0004.
▪ HOLDING REGISTER 102:

ATS115-ATS115Plus Technical Manual 89

 ▪ “71” forces the use of source A.
▪ “72” forces the use of source B.
▪ “74” cancels all forcing at the operation modes (A, B or N).

• System configured with one mains and one genset

This system can be configured setting the source A as mains and the source B as genset and
vice versa, indifferently. For the sake of simplicity, in the rest of the paragraph the Source A
will be referred as mains and the Source B as genset.

In standby, that is without any fault or forcing, and with mains present, loads are always
connected to the source A set as mains (the breaker referred to the ACB mains source is
closed, while the one referred to the BCB genset is opened).

The controller requires the start of the genset (source B) when the mains is no longer available
(mains out of tolerance) or in presence of the fault source A input (DIF.4203 active) or if the
switch (forcing) is required on the source B (DIF.2282 active). Only when the genset B reaches
the operating conditions and the time set in P.0217 – “Delay before supply” passes, the
controller opens the ACB breakers and closes the BCB breaker, switching the loads on the
genset.

The Controller requires the generator to be started (source B) when the mains is no longer
available (mains out of tolerance thresholds) or if the input of source A is faulty (DIF.4203
active) or if the switching (forcing) is required on source B (DIF.2282 active). In case of source
A faulty from digital input or if parameter P.0308 set to “1-At mains failure”, the controller
immediately opens the switch ACB. In all the other cases, only when the generator B has
reached the full speed conditions and the time configured in parameter P.0217 has passed –
“delay before supplying”, the controller opens the switch ACB and closes BCB inverting the
loads on the generator.

Using the parameter “Breaker opening instant” (P.0308 for source A or P.0309 for source B)
is therefore possible to protect the loads moving up the opening of the breaker to the moment
in which the mains is no longer in tolerance.

Once the mains A comes back in tolerance (with proper times) or the mains A is no longer out
of order (DIF.4203 absent) or the forcing request on source B has been removed (DIF.2282
absent), the controller switches the loads on the mains again (it opens the BCB and closes
the ACB) and simultaneously starts the engine stop cycle.

If the switch (forcing) is required on both sources (DIF.2281 and DIF.2282 active
simultaneously), the loads are disconnected from the sources; the controller opens both ACB
and BCB breakers.

When both sources are out of order (DIF.4203 and DIF.4204 active simultaneously), both
related warnings and loads are disconnected from the sources; the controller opens both ACB
and BCB breakers.

The parameter P.0427 “Enable priority” has no effects on this system configuration.
The parameter P.0427 “Enable priority” or a configured input with digital function DIF.2121
have no effect on this plant configuration.

• System configured with two gensets

This system is configured setting both sources A and B as genset. The controller switches on
the other source only when an event (breakdown or forcing) occurs, and it stays steady on it
until the opposed event occurs. Each changeover must be associated to the start of the new
source and to the stop of the one that is no longer necessary.

Generally, in OFF/RESET and MAN mode, both ACB and BCB breakers are open. When the
controller is in AUTO, without breakdown or forcing, it requires the automatic start of the source
A. Once reached the operating conditions and passed the time set in the parameter P.0117 –

90 ATS115-ATS115Plus Technical Manual

“Delay before supply”, the controller closes the ACB breakers. If the operating conditions on
the source A are not reached, the controller tries to start the source B too and closes the BCB
breaker, only if the genset B is in tolerance; otherwise, loads remain disconnected.

Supposing to have reached the steady condition of source B in tolerance and BCB breaker
closed, the controller requires the start of the source A only in case of the source B breakdown
(DIF.4204 active) or if the switch (forcing) on the source A (DIF.2281 active) is explicitly
required. In case of source B breakdown by digital input, the controller opens the BCB
immediately; otherwise, it waits for the source A to be ready. If the operating conditions on the
source A are not reached, the controller stays on the source B; otherwise, it switches the loads
on A (it opens the BCB and closes the ACB) and simultaneously starts the engine stop cycle.

If the switch (forcing) is required on both sources (DIF.2281 and DIF.2282 active
simultaneously), the loads are disconnected from the sources; the controller opens both ACB
and BCB breakers.

When both sources are out of order (DIF.4203 and DIF.4204 active simultaneously), both
related warnings and loads are disconnected from the sources; the controller opens both ACB
and BCB breakers.

The parameter P.0427 “Enable priority” allows to set which one of the two gensets is priority
(allowing the user to define the supply source desired). It acts only in case no breakdown or
forcing on sources. Setting the value “1 – Source A”, the controller activates the genset A and
stops B, consequently opening the BCB breaker and closing the ACB; instead, setting the
value “2 – Source B”, the controller activates the genset B and stops A, consequently opening
the ACB breaker and closing BCB.
The parameter P.0427 “Enable priority” and/or a configured input with digital function DIF.2121
allow to establish which of the two generators is the priority one (allowing the user to define
the preferred supply source). They only act if there are no faults or forcing on the sources and,
if both of them are configured, the function connected to the digital inputs prevails on the
parameter.
When the digital input, configured with the function DIF.2121, is not active, the controller will
active the generator A and will stop B. As a result, it will open the BCB breaker and will close
ACB; on the contrary, when the digital input is active, the controller will active the generator B
and will stop A. As a result, it will open the ACB breaker and will close BCB. While setting
value “1-Source A” the controller will activate generator A and will stop B. As a result, i twill
open the BCB switch and will close ACB; on the contrary, by setting value “2-Source B” the
controller will activate generator B and will stop A. As a result, it will open the ACB switch and
will close BCB.

On page M.01 a flashing little square next to Source A or B indicates which the priority source
is in this moment.

• System configured with two mains

This system is configured setting both sources A and B as mains. The source A is always
considered the referential one, therefore the loads are always connected to it (the ACB breaker
is closed while BCB is opened). It switches on the other source only when an event
(breakdown or forcing) occurs, and it stays steady on it until the opposed event occurs.

The controller switches on the source B when in tolerance, but only when the source A is no
longer available (mains out of tolerance) or in presence of the fault source A input (DIF.4203
active) or if the switch (forcing) is required on the source B (DIF.2282 active). The controller
opens the ACB breaker and closes BCB. In case of source A breakdown by digital input, the
controller opens the ACB immediately.

The controller switches back on the source A when in tolerance, but only when the source B
is no longer available (mains out of tolerance) or in presence of the fault source B input
(DIF.4204 active) or if the switch (forcing) is required on the source A (DIF.2281 active). The
controller opens the ACB breaker and closes BCB. In case of source B breakdown by digital
input, the controller opens the BCB immediately.

ATS115-ATS115Plus Technical Manual 91

 If the switch (forcing) is required on both sources (DIF.2281 and DIF.2282 active
simultaneously), the loads are disconnected from the sources; the controller opens both ACB
and BCB breakers.

When both sources are out of order (DIF.4203 and DIF.4204 active simultaneously), both
related warnings and loads are disconnected from the sources; the controller opens both ACB
and BCB breakers.

The parameter P.0427 “Enable priority” allows to set which one of the two mains is priority
(allowing the user to define the supply source desired). It acts only in case both mains are
present and in tolerance and there are no breakdown or forcing on sources. Setting the value
“1 – Source A”, the controller opens the BCB breaker and closes ACB; instead, setting the
value “2 – Source B”, the controller opens the ACB breaker and closes BCB.

Parameter P.0427 “Enable priority” and/or a configured input with digital function DIF.2121
allow to establish which of the two generators is priority (allowing the user to define the supply
source preferred). They only act in case there are no faults or forcing on the sources and, if
the both of them are configured, the function related to the digital inputs prevails on the
parameter.
When the digital input, configured with function DIF.2121, is not active the controller will
activate generator A and will stop B. As a result, it will open BCB switch and will close ACB;
on the contrary, when the digital input is active, the controller will activate generator B and will
stop A, so it will open ACB switch and will close BCB. While setting value “1-Source A“ the
controller will activate generator A and will stop B. As a result, it will open BCB switch and will
close ACB; on the contrary, by setting value “2-Source B“ the controller will activate generator
B and will stop A. As a result, it will open switch ACB and will close BCB.

On page M.01 a small flashing square next to Source A or B indicates which the priority source
is in this moment.

12.7
The immediate switch function DIF.2002 allows to change the required source to supply the
loads at every input related activation.

The function is enabled:

▪ Only with controller in AUTO.

▪ If at least and input is configured with the function DIF.2002 - “Immediate switch”.
▪ If both sources are available and in tolerance.
▪ If the system is configured with two mains or gensets (it does not support mixed
systems: one mains and one genset).
▪ If there are not damages on the source A or B (no input is set with the function
DIF.2281 or DIF.2282).
▪ If there are not forcing requests on the source A or B (no input is set with the
function DIF.4203 o DIF.4204).
▪ If there are not working start times set on the source A and B (parameter P.0425
different from P.0426 and both different from zero).
▪ If no priority is enabled (parameter P.0427 = 0).

12.8
In MAN and AUTO mode, when the input configured with the function DIF.2003 – “Neutral
position” is active, both ACB and BCB breakers are immediately opened. The controller
displays this status in the last line of the window “S.01” (forcing it immediately) and in a digital
output if configured with the function DOF.3040 – “Both breakers open”.

92 ATS115-ATS115Plus Technical Manual

 It is also possible to force the circuit breakers on this position by means of the commands
received by the serial ports. You need to write in sequence (within 5 seconds) in order to send
the commands:
▪ HOLDING REGISTER 101: write the password configured with parameter
P.0004.
▪ HOLDING REGISTER 102:
▪ “73” forces the use of the Neutral position (the Load remains disconnected
from both source A and B).
▪ “74” cancels all forcing at the operation modes (A, B or N).

The controller records every variation of the neutral position status in the history log, if enabled
with the bit 3 of the P.0441 parameter:

• EVT.1040: Neutral position.

13.
This chapter describes all the malfunctions managed by the controller. Some act as protection
for the loads, for the generator or for the engine. Others are warnings of particular events in
the system management. Before describing them in detail, here are some definitions:
There are two types of malfunctions:
• Warnings: they state situations which are not dangerous at the moment, but that have
to be signalled because, if ignored, they may degenerate in one of the following
categories.
• Blocks: they block the system operation. They are dangerous for the loads and/or for
the engine/genset.
When there is an anomaly, the controller performs the following actions:

• It activates the internal horn and, if configured, the external one too. To that purpose,
you can configure an output of the controller with the function DOF.3152 – “External
horn”. The output is controlled together with the inside beeper; the purpose is that of
using a more powerful beeper or a lamp.

• It forces the page S.02 MALFUNCTIONS on the multifunctional display. This page
shows the numeric code and the current language text related to all active
malfunctioning.

• It activates the flashing of the “ALARM” indicator light, if the anomaly belongs to the
warnings category; it turns it on if the anomaly belongs to the interlocks category.
• If the anomaly is not a warning, the controller disconnects the genset and stops the
engine (with or without the cooling cycle).
An alarm can be activated only if no other alarms are already active (there are some
exceptions to this rule, which will be underlined later). Some warnings can be active.
To issue a warning, no interlock must be present. Some other warnings can be active.

After an anomaly the operator has three choices:

• Silence the horn.

• Acknowledge the anomaly: it means informing the controller that the operator has
acknowledged it.

• Reset the anomaly: it means informing the controller to work as the anomaly has never
been activated.

ATS115-ATS115Plus Technical Manual 93

 13.1
The operator can silence the horn pressing the ACK button:

• Pressing the ACK button.

• Using a command by the serial port. You need to write in sequence (within 5 seconds)
in order to send the commands:

▪ HOLDING REGISTER 101: write the password configured with parameter

P.0004.

▪ HOLDING REGISTER 102: write the value “51”.

The parameter P.0491 (Horn duration) influences the management of the controller horn

• If set to zero, the horn will be never activated.

• If set to 999, the horn will be activated when a new anomaly arises, and deactivated
when the operator presses the ACK button.

• If set to a value between 1 and 998, the horn will be activated when a new anomaly
arises and deactivated when pressing the ACK button, or after P.0491 seconds from
activation.

Silencing the horn does not mean acknowledging the anomaly: in fact, it continues to flash on
page S.02 MALFUNCTIONS.

13.2
The operator can “acknowledge” the anomaly (sequence ISA2C) in two ways:

• Pressing the ACK button.

• Using a command by the serial port. You need to write in sequence (within 5 seconds)
in order to send the commands:

▪ HOLDING REGISTER 101: write the password configured with parameter

P.0004.

▪ HOLDING REGISTER 102: write the value “52”.

When the anomaly has been acknowledged, it stops flashing on page S.02 MALFUNCTIONS.
Once acknowledged, in case of a warning, it is automatically cancelled, if its cause is no longer
present.
Instead, if the cause disappears before the anomaly is acknowledged, it will remain on the
display.

13.3
The operator can “reset” the anomaly, setting the controller in OFF/RESET, in three ways:

• Pressing the ACK button.

• Using a command by the serial port. You need to write in sequence (within 5 seconds)
in order to send the commands:

▪ HOLDING REGISTER 101: write the password configured with parameter

P.0004.

▪ HOLDING REGISTER 102: write the value “53”.

• Using a digital input configured with the function DIF.2001 – “Alarm reset command”.
When the input becomes “active”, the controller carries out a complete reset of all
faults.

94 ATS115-ATS115Plus Technical Manual

 When the controller performs a malfunctions reset, it also activates for a second the
outputs configured with the function DOF.3151 – “Anomaly reset”. That is useful to take
advantage of the reset control command to reset alarms on external devices.

13.4
All malfunctioning is recorded (each one with its own code) in the events log.
There are some functions for the configuration of the digital outputs related to the malfunctions:

• DOF.4001 - “Warnings”. The output is “active” if there is at least one warning.

• DOF.4004 - “Alarms (interlocks)”. The output is “active” if there is at least one interlock.

• DOF.4035 - “Breakers anomaly”. The output is “active” if there is at least one warning
related to the breakers ACB or BCB.
In addition, the controller makes the SOURCE A and SOURCE B status available to the
AND/OR logics by means of the following internal statuses:

• ST.008 - "Warnings cumulative"

• ST.011 - "Interlocks cumulative"

• ST.012 - "Unacknowledged warnings cumulative"

• ST.015 - "Unacknowledged interlocks cumulative"

13.5
NOTE: since you cannot define in advance neither which digital or analogue inputs will be
used (the controller or the additional modules ones), nor what function they will perform, the
list below refers to the parameters of the first configurable input, as example. The symbol (*)
or the indication “or equivalent for the other inputs” next to a parameter shows that it varies
according to the particular input configured.

 14.
14.1
The controller manages internally the following counters:

• Partial active power counter (kWh) (resettable), increased when the loads are
connected to the source A.

• Total active power counter (kWh), increased when the loads are connected to the
source A.

• Partial reactive power counter (kWh) (resettable), increased when the loads are
connected to the source A.

• Total reactive power counter (kWh), increased when the loads are connected to the
source A.

• Partial working hours counter (hh) (resettable), increased when the loads are
connected to the source A.

• Total working hours counter (hh) (resettable), increased when the loads are connected
to the source A.

• Partial active power counter (kWh) (resettable), increased when the loads are
connected to the source B.

• Total active power counter (kWh), increased when the loads are connected to the
source B.

• Partial reactive power counter (kWh) (resettable), increased when the loads are
connected to the source B.

• Total reactive power counter (kWh), increased when the loads are connected to the
source B.

• Partial working hours counter (hh) (resettable), increased when the loads are
connected to the source B.

• Total working hours counter (hh) (resettable), increased when the loads are connected
to the source B.

All these counters are displayed on the controller front panel and can be read via serial port
(with the ModBus protocol). Some of these counters can be reset by the operator following a
proper procedure, or via serial port (they are marked in the list with “resettable”). All these
counters are saved in a non-volatile memory, so they store their values also when the
controller is powered off. Non-volatile memories have limited life cycles, therefore it is
important to reduce the memory writing to minimum. For this reason, a counter may not be
immediately saved as its value changes; consequently, before powering the controller off, it is
important to ensure to know when and how the counters were saved.

Counters are saved (all together and simultaneously) in the following conditions:

• Every time the controller is in OFF/RESET mode.

• For each hour the controller is powered.

Furthermore, counters are saved when they are reset to zero (individually or globally) via front
panel or serial port. Note that some counters have a decimal part (for example the minutes-
counters associated to hours-counters), which is also saved in a non-volatile memory.
Powering off the controller in an uncontrolled way can cause the loss of the decimal part. It is
enough to switch the controller to OFF-RESET to force data saving, before switching off the
power.

102 ATS115-ATS115Plus Technical Manual

14.1.1 Counters reset
The resetting procedure is common for all the counters, but it only applies to some of them,
based on the page displayed on the multifunctional display. See in paragraph 11.5.3.9 and
11.5.3.10 the description of the display pages that contain the counter to reset to zero.

14.2
The controller is provided with a standard hardware clock. It is shown in detail in the page S.05
CONTROLLER. It can be set through the programming menu 4.7.1 – Date/Time or the serial
port, and it is used for many functions:

• History logs recordings (see par. 11.5.4).

• Weekly planning of time intervals in which the source, set as genset, can be used.

• Hourly planning of time intervals in which the switch-over between sources should
happen.

• Daily planning of the start working hour for each source.

14.2.1 Automatic clock upgrade

If the controller is equipped with an Ethernet connection, the controller clock can be
automatically upgraded by the connection to a NTP server (see par.10.4). The controller
consults the server every 5 minutes and records the event “EVT.1076 – Date and Hour
changed” in the history log, only if the difference between the new data received and the actual
one is higher than a minute. The server returns the date and the hour of the reference time
zone (that is the UCT time, “Coordinated Universal Time”), from which the controller can
calculate and upgrade the internal calendar, considering its time zone and legal time.

For this purpose, there are the following parameters:

• P.0409: Legal time.

• “0 - No” Legal time not in use: Time is not changed.

• “1 - Yes” Legal time in use: It adds an hour to the one received.

• “2 - Automatic (Europe only)”: It automatically calculates if the legal hour is in use. It

only works for Europe, since starting from 2002 it has been unified (it activates at
01:00 in the last Sunday of March and deactivates at 01:00 in the last Sunday of
October).

• “3-Automatic (via calendar)”: the activation/deactivation of the daylight save time is

configurable by calendars 15 and 16.

• P.0410: Time zone (1=15 min / 4=1 hour).

The setting limits are from -47 to + 48 and they allow to manage all hour ranges of the
Earth in quarters of hour.

14.2.2 Weekly planning of the working hours

In some applications, it can inhibit the automatic working of the source/s configured as
genset/s in hour or days in which its intervention is not necessary. For example, if there is
nobody in a factory on Sunday, letting the genset work for lack of mains is useless (actually, it
is a waste of fuel). This function precisely aims to set in which days and hour ranges the
automatic intervention of the genset is adequate. The planning is weekly: it is possible to set
in which days the genset can intervene. In addition to the days, it is possible to set a unique
hour range of automatic intervention authorisation, that will be the same for all days selected.

This planning inhibits the intervention of the source/s set as genset (by means of the
parameters P.0100 and P.0200 – Source type), while it has no effects on the ones set as
mains.

ATS115-ATS115Plus Technical Manual 103

 The parameters that allow to make these configurations are:

• P.0421 – “Generator enable days”: It allows to specify in which days of the week the
genset can automatically intervene. It is a bit-configurable parameter, each of them
corresponds to a day of the week. In order to obtain the value of the parameter, sum
up the “value” of the following table for the interested days.

Bit Value Day

0 1 Sunday
1 2 Monday
2 4 Tuesday
3 8 Wednesday
4 16 Thursday
5 32 Friday
6 64 Saturday

• P.0422 – “Generator enable start time”: It allows to set the start of the range in which
the automatic intervention is approved, in hours and minutes.

• P.0423 – “Generator enable stop time”: It allows to set the stop of the range in which
the automatic intervention is approved, in hours and minutes.

Generally, P.0422 will be set at a value lower than P.0423. Instead, if it contains a higher
value, the controller considers the selected range as over midnight: in this case, the hour set
in P.0422 refers to the days selected in P.0421, while the hour set in P.0423 refers to the
following days.

For example, intending to enable the genset automatic intervention only from Monday to
Friday, from 08:00 to 18:00, it is necessary to set:

P.0421 = 62 (2+4+8+16+32)

P.0422 = 08:00

P.0423 = 18:00
The controller makes available, for AND/OR logics, also the internal status ST.081 -
"Clock/calendar start inhibition”.

14.2.3 Hourly planning of the switch-over interval

The hourly planning of the switch-over interval defines every how many hours of work the
source change is required. For example, it can be useful, if the plant manages the switching
between two gensets to share the working hours between the two gensets in the day time.
The parameter which allows to set this configuration is:

• P.0424 – “Switch-over interval”: It allows to set in which interval time the switch of the
source is required.

The time counting starts following to a new setting of the parameter P.0424 and it is not reset
with the controller in OFF/RESET mode. Only when the source is working (exactly when the
related breaker is closed) the time counting is performed. The switch-over of the source will
be carried out with the controller in AUTO mode.

14.2.4 Daily planning of the working hours

In some applications, it can set default working hours for both sources. For example, if the
cost of the energy absorbed by the mains is higher in some hour ranges, it could be appropriate
to use the genset in that period. This function can precisely set at what time of the day the
sources must be activated.

The parameters that allow to make these configurations are the following:

104 ATS115-ATS115Plus Technical Manual

 • P.0425 – “Source A enable start time”: It allows to set the start of the range in which
the automatic intervention of the source A is required, in hours and minutes.

• P.0426 – “Source B enable start time”: It allows to set the start of the range in which
the automatic intervention of the source B is required, in hours and minutes.

Setting both P.0425 and P.0426 parameters equal to zero, the function is disabled.

In case of fault of the source required, the controller will automatically switch on the other. It
will return on the one required once the malfunction is restored.

For example, intending to enable the intervention of the source A from midnight to midday and
of the source B from midday to midnight, it is necessary to set:

P.0425 = 00:00

P.0426 = 12:00
The controller makes available, for AND/OR logics, also the internal status ST.082 - "Working
hour for Source B (OFF = A)”, in order to identify the actual hour range and the source is
required.

14.2.5 Configurable calendars

The controller provides 16 calendars fully configurable. They allow to select days and time-
slots, inside which the controller activates an internal bit. This bit could then be used by
AND/OR logics to activate a digital output or to create more complex logics. All calendars are
identical: calendars 15 and 16, however, can be used for the activation/deactivation of the
daylight save time (if parameter P.0409 is set to “3”).

Each calendar can be individually selected as “monthly” or “weekly”:

ATS115-ATS115Plus Technical Manual 105

 Using BoardPrg3 software, it is very easy to select whether a calendar is “weekly” or “monthly”.
If you want to use the parameters of the controller, you must act on the parameter P.1900. It
is a bit-field parameter; one bit is provided for each calendar:
BIT Value Hexadecimal Calendar
0 1 0001 Calendar 1
1 2 0002 Calendar 2
2 4 0004 Calendar 3
3 8 0008 Calendar 4
4 16 0010 Calendar 5
5 32 0020 Calendar 6
6 64 0040 Calendar 7
7 128 0080 Calendar 8
8 256 0100 Calendar 9
9 512 0200 Calendar 10
10 1024 0400 Calendar 11
11 2048 0800 Calendar 12
12 4096 1000 Calendar 13
13 8192 2000 Calendar 14
14 16384 4000 Calendar 15
15 32768 8000 Calendar 16

The parameter must be set with the sum of the values for all the calendars that must be
selected as “weekly” (in hexadecimal notation). In fact, a bit set to “1” selects the “weekly”
mode.

Both calendar types allow to select in which months the controller activates the internal bit (at
least one month must be selected, it is even possible to select all months). Using the
parameters of the controller, this selection is done by means parameter P.1901 (for the
calendar 1 or equivalent for other calendars). This is also a bit-field parameter:

BIT Value Hexadecimal Month

0 1 0001 January
1 2 0002 February
2 4 0004 March
3 8 0008 April
4 16 0010 May
5 32 0020 June
6 64 0040 July

8 256 0100 September
9 512 0200 October
10 1024 0400 November
11 2048 0800 December

The parameter must be set with the sum of the values of the required months (in hexadecimal
notation).

For “monthly” calendars, is then possible to select the days of the month for the activation of
the internal bit (at least one day must be selected, it is even possible to select all days). Using
the parameters of the controller, this selection is done by means parameter P.1902 (for the
calendar 1 or equivalent for other calendars). This is also a bit-field parameter:

BIT Value Hexadecimal Day of month

0 1 00000001 1
1 2 00000002 2
2 4 00000004 3

29 536870912 20000000 30
30 1073741824 40000000 31

The parameter must be set with the sum of the values of the required days (in hexadecimal
notation).

For “weekly” calendars, is then possible to select the days of the week for the activation of the
internal bit (at least one day must be selected, it is even possible to select all days). Using the
parameters of the controller, this selection is done by means parameter P.1902 (for the
calendar 1 or equivalent for other calendars). This is also a bit-field parameter:

ATS115-ATS115Plus Technical Manual 107

 BIT Value Hexadecimal Day of week
16 65536 00010000 Sunday
17 131072 00020000 Monday
18 262144 00040000 Tuesday
19 524288 00080000 Wednesday
20 1048576 00100000 Thursday
21 2097152 00200000 Friday
22 4194304 00400000 Saturday

The parameter must be set with the sum of the values of the required days (in hexadecimal
notation).

Selecting a day of the week (Sunday for example), it is then possible to select if all “Sundays”
in the month must be used or only some of them. Using the parameters of the controller, this
selection is done by means parameter P.1902 (for the calendar 1 or equivalent for other
calendars). This is also a bit-field parameter:

BIT Value Hexadecimal Occurrence

0 1 00000001 First occurrence
1 2 00000002 Second occurrence
2 4 00000004 Third occurrence
3 8 00000008 Forth occurrence
4 16 00000010 Last occurrence

The parameter must be set with the sum of the values of the required occurrences (in
hexadecimal notation). Note: for “weekly” calendars, the days of week and their
occurrences in the month are selected by the same parameter, using different bits.

If the “occurrence” bits are all “0”, then the selected days of week will be managed in any week
of the month; otherwise they will be managed for the selected occurrences only. The “last”
option is useful because, depending on the month and on the year, a certain day of the week
can be present 4 or 5 times in a month: using the “last” option you can do an action exactly in
the last occurrence in the month. A typical example is the management of the daylight save
time; in Italy, it is activated on the last Sunday of October, and deactivated on the last Sunday
of March. Those Sundays can be the 4° or the 5° occurrence in the month, depending on the
first day of the month. Using the “last” option, the problem is solved.

Finally, for both “weekly” and “monthly” calendars, it is possible to select a time-slot (valid for
all selected days). The controller will activate the internal bit only inside the selected time-slot.
Using the parameters of the controller, the time-slot can be selected by means P.1903 and
P.1904 (for the calendar 1 or equivalent for other calendars). If those parameters are set with
the same values, the full day is selected. If the start time is lower than the end time, the time-
slot is not across midnight; otherwise, the internal bit is activated after the start time of the
selected days, and it is deactivated after the end time of the day after the selected one.

Using the AND/OR logics, it is possible to activate a digital output into selected days and time-
slot (selected using a calendar):

108 ATS115-ATS115Plus Technical Manual

This is an example for the configuration of the daylight save time for Italy, using calendars 15
and 16:

• Calendar 15.

o Select “weekly” (bit 14 of P.1900 = “1”).

o Last Sunday of October:

▪ Select “October” (P.1957 = “0200”).

▪ Select “Sunday”, “Last” (P.1958 = “00010010”).

o The activation should happen at 02:00:

▪ Select “2:00” as start time (P.1959).

▪ Select “2:01” as end time (P.1960).

• Calendar 16.

o Select “weekly” (bit 15 of P.1900 = “1”).

o Last Sunday of March:

▪ Select “March” (P.1961 = “0004”).

▪ Select “Sunday”, “Last” (P.1962 = “00010010”).

o The activation should happen at 03:00:

▪ Select “3:00” as start time (P.1963).

▪ Select “3:01” as end time (P.1964).

 14.2.6 Configurable timers
The controller provides 4 generic timers fully configurable, that can be used inside the AND/OR
logics to create complex sequential logics. Each timer, in fact, activates/deactivates an internal
bit that can be used by the AND/OR logics.

The four timers are identical.

For each timer it is possible to select (by means an AND/OR logic) an “activation condition”
that starts the timer. In the same way, it is possible (but not mandatory) to select (by means
an AND/OR logic) a “reset condition” that resets the timer. When the “reset condition” is true,
the internal bit of the timer is forced to “0”.

Moreover, each timer provides the following five parameters (the list refers to the timer 1):

• P.2901: function of the timer 1.

• P.2902: Activation delay format for the timer 1.

• P.2903: Activation delay for the timer 1.

• P.2904: Deactivation delay format for the timer 1.

• P.2905: Deactivation delay for the timer 1.

110 ATS115-ATS115Plus Technical Manual

In addition to the function, two delays are configurable for any timer; for each of them it is
possible to select the time base (“0 – Seconds”, “1 – Minutes”, “2 – Hours”) and the delay
value.

Each timer can work in four different modes, selectable by means parameter P.2901 (for the
timer 1 or equivalent for the other timers):

• 0 – Not used. In this case the internal bit related to the timer is always reset.

• 1 – Delay.

o The internal bit is reset while the “reset condition” is true.

o The internal bit is set with the delay P.2902 – P.2903 from when the “activation
condition” becomes true.

o The internal bit is reset with the delay P.2904 – P.2905 from when the
“activation condition” becomes false.

• 2 – Pulse.

o The internal bit is reset while the “reset condition” is true.

o The internal bit is set for the time configured with P.2902 – P.2903 each time
the “activation condition” changes from false to true.

o The internal bit is set for the time configured with P.2904 – P.2905 each time
the “activation condition” changes from true to false.

• 3 – Free run

o The internal bit is reset while the “reset condition” is true.

o The internal bit is reset while the “activation condition” is false.

o While the “activation condition” is true, the internal bit is managed as a square
wave: it is set for the time configured with P.2902 – P.2903, then it is reset for
the time configured with P.2904 – P.2905, and so on.

• 4 – Set/Reset

o The internal bit is reset while the “reset condition” is true.

o The internal bit is set if the “activation condition” is true and the “reset
condition” is false.

o The internal bit keeps its previous status if the “activation condition” is false
and the “reset condition” is false.

The following example manages a digital output related to the internal bit of the timer 1:

ATS115-ATS115Plus Technical Manual 111

 14.3
The controller has a non-volatile memory inside, used to store various information such as
parameters, counters etc. The memory is divided in different areas. When the controller is
powered, it performs a check on the data stored in each area: if even just one area is incorrect,
it displays an error message with a numerical code (in hexadecimal form); each bit to 1 of said
code corresponds to an area of the memory that is not valid. Here is a table listing the areas
and their bit.

Area Version Bit Value Description

1 1.00 0 1 (0001) Coefficients for the calibration of the measuring inputs of
the controller.
2 1.00 1 2 (0002) Various information (language selected, LCD display
contrast).
3 1.00 2 4 (0004) Counters.
4 1.00 3 8 (0008) Reserved.
5 1.00 4 16 (0010) Parameters.
6 1.00 5 32 (0020) Text parameters
(e.g. configurable messages related to the inputs)

If, for example, the value between brackets is “0004”, it means that only the counters area is
not valid. If the value is “0022”, it means that the parameters areas (0020) and the current
language area (0002) are not valid.

If any of the areas is not valid, the normal operating sequences are not carried out until the
operator presses the “ENTER + EXIT” buttons: in fact, the situation must be taken note of,
because it may cause malfunctions (for example, imagine what would happen if the invalid
area was the one of the parameters). Only when the operator presses “ENTER + EXIT”, the
controller reloads the default settings for the data stored in the invalid areas: this means that,
if the controller is turned off without pressing “ENTER + EXIT”, next time you turn it on you will
get the invalid memory report again.
