2 Functional description

2.1 What must one pay attention to in the event of ...

2.1.1 ... different options

In accordance with its configuration, the item may differ from the maximum expansion via the following characteristics:
• The inputs and outputs are present or not present, corresponding to the item configuration (depending on your order). Please refer
to the wiring diagram and the notes on the options contained in these. Refer to the type plate to see whether or not the correspond-
ing option is contained in the item. If the type plate has been removed, all configuration screens can be called up in succession
and the options can be compiled with the assistance of this manual.
• There are different screens for the various types of interfaces.

2.1.2 ... systems with one power circuit breaker

If an item with a 2-power-circuit-breaker logic [PCM1-M] or a 1-power-circuit-breaker logic [PCM1-G] is installed for use with one
power circuit breaker, the following shall apply:

• If the stationary permanent operation application is to be operated in isolated or isolated parallel operation (the MCB is opened),
the following signals have to be applied:
- "Reply: MCB is open" / "Isolated operation" (term. 54): HIGH signal (log. "1") and
- "Enable MCB" (terminal 53): LOW signal (logical "0").
- Condition: The "Emergency power" must be set to "OFF".
• If the stationary permanent operation application is to be operated in mains parallel operation (the generator operates always in
mains parallel if the GCB is closed), the following signals have to be applied:
- "Reply: MCB is open" / "Isolated operation" (term. 54): LOW-Signal (log. "0") and
- "Enable MCB" (terminal 53): HIGH signal (logical "1").
• If the application is to be operated in isolated(parallel) as well as in mains parallel operation (the MCB can be opened or closed),
the following signals have to be applied:
- Reply, that the GCB is closed (terminal 4) and
- Reply, that the MCB is closed (terminal 54) and
- "Enable MCB" (terminal 53)

Case A - The MCB has to remain closed (except at an emergency power operation): The "Enable MCB" (terminal 53) always has to
be logical "1".

Case B - The MCB can be opened (also outside an emergency power operation): The "Enable MCB" (terminal 53) has to be logical
"1" if a mains parallel operation has to be established (a synchronization of the MCB has to be performed). During the synchroniza-
tion of the MCB (PCM1-G: External) the generator frequency is controlled with a slightly higher value than the mains frequency (df
max/2). Additionally a message is issued at the display. The "Enable MCB" (terminal 53) has to be logically "0", if the system has to
be operated in isolated operation (control of setpoint frequency and setpoint voltage).

2.3 Control inputs

NOTE

Any possible emergency power ("Emergency power" configuration screen must be set to ON) or sprinkler
operation (terminal 6 must be configured accordingly) will be carried out in the "TEST" and "AUTOMATIC"
operating modes regardless of the discrete inputs "Automatic 1" and "Automatic 2". If terminals 3 and 5
are set simultaneously, preference is given to terminal 3.

Automatic 1 Selection of the operating mode "AUTOMATIC" with "Active power setpoint value 1" as
Terminal 3 well as starting/stopping of the engine.
Set.................If the item is in "AUTOMATIC" mode (selected using the mode selection
switch on the front side) the "active power setpoint value 1" is adjusted in
mains parallel mode. In the case of a fixed power (F), the engine is
started immediately and operation in parallel with the mains is com-
menced following the synchronization of the generator power circuit
breaker. In the case of incoming/import (B) or outgoing/export power (L),
starting is determined by automatic start/stop (start/stop) operation. If no
automatic start/stop operation is enabled, the engine is started immedi-
ately. The setpoint value can be modified via both the configuration mode
and via the "up/down" push-buttons in "AUTOMATIC" mode.
AUTOSTART
Reset ..............If the engine does not run either in sprinkler mode or emergency power
mode, it is stepped. Then a coasting is carried out and the engine is
stopped.

Automatic 2 Selection of the "AUTOMATIC" mode with "Active power setpoint value 2" as well as
Terminal 5 starting/stopping of the engine.
Set.................If the item is in "AUTOMATIC" mode (selected using the mode selection
switch on the front side) the "Active power setpoint value 2" is adjusted in
mains parallel mode. In the case of a fixed power (F), the engine is
started immediately and operation in parallel with the mains is com-
menced following the synchronization of the generator power circuit
breaker. In the case of incoming/import (B) or outgoing/export power (L),
starting is determined by automatic start/stop operation. If no automatic
start/stop operation is enabled, the engine is started immediately. The
setpoint value can be modified via both the configuration mode and via
the "up/down" push-buttons in "AUTOMATIC" mode. AUTOSTART
Reset ..............If the engine does not run either in sprinkler mode or emergency power
mode, it is stopped. Then a coasting is carried out and the engine is
stopped.

If a setpoint value is specified externally (e. g. via an analog input 0/4..20 mA or a bi-directional
interface), the external setpoint value is adjusted with the discrete input (see Table of setpoint values).

28 HB_PCL1/PCM1-M/PCM1-G_09.04_GB
 Multifunction Discrete input terminal 6 may reveal different functions according to the following description. Please
Terminal 6 note that, when used as a sprinkler input, the discrete input reveals negative functional logic. The
selection of the logic circuit is made using a configuration screen (Chapter 4.15.3 "Setting the control
inputs ", Page 135).

• Sprinkler By resetting terminal 6 (setting a low level) sprinkler operation is activated in accordance with the
functional description. This is terminated by setting terminal 6 (application of a High signal). Attention:
Negative functional logic! (for the function of the sprinkler operation, please also observe Chap-
ter 2.11 "Sprinkler operation" on page 53.)

• Engine enable Terminal 6 in this case has the same function as the STOP push-button: Resetting terminal 6 (applica-
tion of a LOW signal) prevents the engine's starting, and stops the engine if this is already running; the
application of a HIGH signal enables the starting of the engine; the application of a high signal en-
ables the engine for startup. Caution: Via this function, emergency power operation is also prevented
or aborted. Emergency power is not possible without this enable signal! The engine enable function is
only possible in "AUTOMATIC" operating mode.

• Ext. acknowledge In "STOP" and "AUTOMATIC" modes alarms can be acknowledged externally by setting terminal 6
(Change of slope from a LOW to a HIGH signal). In order to achieve further acknowledgement, ter-
minal 6 must accordingly first be reset and then set again. If a continuous HIGH signal is present at
terminal 6, this has no effect on the acknowledgement and suppression of alarm messages.

••STOP mode By setting terminal 6 (application of a HIGH signal) the STOP mode is chosen. If you remove this
signal the mode will change into the mode which was activated before terminal 6 was set.

• Engine stop By setting terminal 6 (application of a HIGH signal) a start of the engine can be prevented. If the
engine is running because emergency current is present, it is stopped by setting this discrete input. The
discrete input is not inverted. The engine block function is only possible in "AUTOMATIC" operating
mode.

• No CB by start If the terminal 6 is set, the engine starts; no synchronization is carried out and the generator power
circuit breaker is not engaged (no switching to black busbar). The GCB is then inserted only if emer-
gency current is present. After return of the mains, there is a switchover to the mains according to the
set CB logic. The start of terminal 6 is of a higher value than the start via terminals 3/5. If terminal 6
was selected, terminals 3/5 are ignored. If the genset is in mains parallel mode with power circuit
breaker logic "Parallel" and if terminal 6 is activated, the GCB is opened after a reduction in power.
The genset continues to operate without load with the GCB open.

Readiness for operation Setting the relay signals the readiness for operation of the item. If this relay drops out, the perfect
Terminals 18/19 function of the item can no longer be guaranteed. Appropriate measure must be introduced if this
relay has dropped out (e.g. open GCB, shut down engine).

Preheating (Diesel engine) When this relay is set the diesel engine is preheated (see functional description of diesel engine start

Fuel relay/gas valve Terminals 43/44

a) Diesel engine: fuel relay
a.1) Operating magnet
Setting this relay will initiate the starting sequence of the diesel engine. If the engine is to be shut-down the relay will
immediately drop out. If the speed of the engine drops below the adjustable ignition speed, the relay also drops out
(note chapter "Diesel engine").
a.2) Stopping magnet
Setting this relay will stop the engine.

b) Gas engine: Gas valve

Setting this relay will open the gas valve for the gas engine. If the engine shall be shut down, the relay drops out di-
rectly. If the engine speed falls below the adjustable firing speed, the relay drops out as well (please note the descrip-
tion in chapter „Gas engine“).

Starter By setting this relay the starter will be engaged. When the firing speed is reached or when there is a
Terminals 45/46 stoppage or after the flow of the engagement time the starter is disengaged (see chapter 2.6
"Description starting/stopping process" starting at page 37).

 Centralized alarm By setting this relay, a centralized alarm is output. In this case e. g. a horn or buzzer is triggered. The
[PCL1] pre-ass. to relay 4, term. 47/48 operator can reset the relay by pressing the push-button "RESET/CLEAR" for a short period. The relay
[PCM1x] pre-ass. to relay 7, term. 47/48 will be set again in the event of another alarm. The centralized alarm is set for alarms of alarm
class F1 through F3 (see page 62).

Command: close GCB By setting this relay the generator power circuit breaker (GCB) will be closed. If the GCB connection
Terminals 14/15 is configured to continuous pulse, in response to a missing discrete input "Reply: GCB is open" the
relay is maintained in its closed state; this is also the case if the voltages of the generator and the
generator busbar are identical. In the event of an alarm of the alarm class 2 or 3, or the GCB is to
be opened, this relay drops out. In the event of an alarm of alarm class 2 the relay does not drop out
immediately, but only if the power is less than 3.125 % of the generator power rating (see page 84).
If the switching of the GCB is not configured to continuous pulse, the relay drops back out after a
pulse is output. Then, the self-holding of the GCB must be carried out externally.

"Interf.err.X1X5" Interface X1..X5 malfunction. External control signals cannot be received.

"GCB syn. failure" If the synchronization time for the generator power circuit breaker has been exceeded, this message
is shown in the display. At the same time, an alarm class F1 alarm is output.

"MCB syn. failure" If the synchronization time for the mains power circuit breaker has been exceeded, this message is
shown in the display. At the same time, an alarm class F1 alarm is output.

"GCB open failure" If closing of the GCB was not successful following 5 switching attempts, the message "GCB close
"GCB close failure " failure" is shown in the display. If it is present 2 seconds following the "Command: GCB open" pulse,
"Reply: GCB is open" is still present, the message "GCB open failure" is displayed. At the same time,
an alarm class F1 alarm is output.

"MCB open failure" If closing of the MCB was not successful following 5 switching attempts, the message "MCB close
"MCB close failure" failure" is shown in the display. If it is present 2 seconds following the "Command: MCB open" pulse,

 "Fault df/dVmax." If, following starting and the expiration of the set time "GCB black start max. time" the generator does
not reach the voltage and frequency window allocated to it, this message is displayed.

"Start fail" This message is output following three unsuccessful starting attempts. No further attempt at starting is
made. In sprinkler operation, starting is attempted six times before this message is displayed.

"Stop failure" If speed is still detected 30 seconds following the stop signal, (acquired by the generator frequency,
the Pickup or the discrete input "Dynamo") the message "Stop failure" is output with an F3 alarm
shutoff.

"Service" Following the expiry of the maintenance interval, the imminence of the next maintenance is displayed
with this message.

"Not wanted stop" The engine's starting process was completed and the engine should run. This message is displayed if
the generator frequency suddenly drops to 0 Hz, e.g. due to mechanical damage. (Background note:
Since the delayed engine monitoring is deactivated when the firing speed is not reached, no under-
frequency can be detected. This message is not suppressed due to the delayed engine monitoring.)

"P-Ramp: GCB open" If the GCB can not be opened after stopping the engine in the time range of "add/stop ramp max.
time" this alarm message will be displayed (this message shows that the P control potentially has a
fault).

Preheating time (0..99 s) tVG = 3 s
Engagement time (0..99 s) tEin = 5 s
Time between two start attempts (0..99 s) tSPZ = 10 s

Function If the item is equipped with a three-position frequency controller, the relay "Frequency
lower" is output prior to the starting process for the "Frequency controller initial state" time.
Then the relay "Preheating" will be set for the period of the preheating time. Following pre-
heating, the operating magnet is first set, and then the starter. When the adjustable firing
speed is exceeded, the starter is disengaged again, and the operating magnet is held via
the firing speed. After reaching "start frequency f-controller" of the speed controller and after
expiration of the delay time, the speed controller is activated.

b.) Stopping process

Coasting time (0..999 s) tN = 3 s

Function Upon resetting the operating bit, power reduction (if the active load controller is switched
on) is carried out. After opening the generator power circuit breaker, the coasting time is
started, and the engine rotates without load. On termination of the coasting time, the oper-
ating magnet is reset. The engine is stopped. If the firing speed is not reached, engine
starting is prevented for a firmly pre-specified time of 10 seconds. If the engine cannot be
stopped via the operating magnet, after 30 s, the "Shutoff malfunction" alarm message ap-
pears; a class 3 alarm is output.

Engagement time (0..99 s) tEZ = 15 s
Time between two start attempts (0..99 s) tSPZ = 10 s

Function If the item is equipped with a three-position frequency controller, a continuous signal (time
adjustable) is output prior to starting the engine at the "Frequency down" relay output. The
starter is then set. Following the expiration of the firing delay time and if the engine is rotat-
ing with at least the set "minimum speed start", the ignition is switched on. Following the
expiry of the gas delay, the gas valve is then switched on. If the starting attempt is success-
ful, i.e., the firing speed was exceeded, the starter is disengaged again. The gas valve
and the ignition are held via the firing speed. After reaching the "starting frequency f-
controller" and after expiration of the delay time, the speed controller is activated.

b.) Stopping process

Coasting time (0..999 s) TZN = 3 s

Function On resetting the starting request, power reduction (if the active load controller is switched
on) is carried out. After opening the generator power circuit breaker, the coasting time is
started, and the engine rotates without load. On termination of the coasting time, the gas
valve is closed. The engine is stopped. If the firing speed is not reached, engine starting is
prevented for a firmly pre-specified time of 10 seconds. If the engine cannot be stopped,
the "Shutoff malfunction" alarm message appears after 30 s, a class 3 alarm is output.

Following negative deviation from the firing speed, the ignition remains set for a further
5 seconds so that the remaining gas is able to combust.

2.8 Monitoring power circuit breakers

2.8.1 Breaker connect time monitoring

If, in the case of synchronous generators, the "synchronization time monitoring" mask or, in
the case of asynchronous generators, the "breaker connection monitoring" mask is set to
"ON", synchronization time monitoring (connection monitoring in the case of asynchronous
generators) is carried out: If the synchronization of the GCB or MCB is started, the time
counter is started following the expiry of delayed engine monitoring. If, following the expiry
of the set time, the power circuit breaker has not been activated, a warning message
"GCB synchronization time exceeded" ("GCB connect time exceeded" in the case of asyn-
chronous generators) or "MCB synchronization time exceeded" is output as an F1 alarm.

2.8.2 Circuit breaker monitoring

NOTE

If during active "MCB monitoring", circuit breaker monitoring, an alarm is detected on closing the MCB,
this is carried out during activated emergency power.

Upon CLOSING If the " GCB monitoring" or "MCB monitoring" is set to "ON", generator and mains power
circuit breaker monitoring is carried out (exception: the power circuit breaker logic is set to
"EXTERNAL"). If the circuit breaker cannot be activated by the fifth attempt, an alarm
class F1 "GCB malfunction" or "MCB malfunction" alarm message is output. If the relay
manager is available (see chapter 4.17.2 "Relay manager" starting at page 132) a relay
is set with the parameter 74 or 75.

Upon OPENING If the reply is still detected 2 seconds after a CLOSE pulse (opening of GCB or MCB) that
the GCB or MCB is closed, an alarm message of alarm class F1 "GCB malfunction" or
"MCB malfunction" is also output. If a relay manager is available, a relay is set with pa-
rameter 76 or 77.

page 110. The synchronization conditions as described in chapter 0 "
Synchronization of the " starting on page 41 and chapter 2.7.3 "Synchronization of the MCB" starting on
page 43 are applicable.

2.9.1 CB logic "PARALLEL" [PCM1x]

NOTE

This CB logic must be selected for the following operating modes: isolated operation, isolated operation in
parallel with other gensets and operation in parallel with the mains.

In the event of an engine request,

• the GCB is synchronized and closed, and
• the necessary generator real power or re-active power is adjusted.

Following the withdrawal of the engine request,

• the generator power is reduced, the generator power factor ϕ is adjusted to "1",
• the GCB is opened and
• the engine is shut off following coasting.

The mains power circuit breaker is synchronized and closed if

• terminal 53 "Enable MCB" is set and
• the GCB is closed.

The mains power circuit breaker is switched to the black busbar if

• the GCB and

2.9.2 CB logic "INTERCHANGE" [PCM1-M]

Interchange synchronization is activated via the "INTERCHANGE" (interchange synchroni-

zation screen input.
NOTE

In order to perform this function correctly, you have to obey that the mains power measurement is
connected properly. The sign of the power measurement has to be determined correctly as well.

In the event of a engine request, a switch is made from mains to generator supply. In order
to achieve this,
• the GCB is synchronized and closed,
• the mains interchange is adjusted to "zero" and
• the MCB is opened.

After the engine request has been reset, a switch is made from generator to mains supply.
In order to achieve this,
• the MCB is synchronized and closed,
• the generator power is adjusted to "zero" and
• the GCB is opened.

2.9.3 CB logic "CLOSED TRANSIT." [PCL1/PCM1-M]

Closed transition (no-break-transfer/overlap synchronization) is activated via the "CLOSED

TRANSIT." screen input.

In the event of a engine request, a switch is made from mains to generator supply. In order
to achieve this,
• the GCB is synchronized and closed and
• the MCB is opened.

After the engine request has been reset, a switch is made from generator to mains supply.
In order to achieve this,
• the MCB is synchronized and closed and
• the GCB is opened.
NOTE

The power circuit breakers are opened regardless of the power.

2.9.4 CB logic "OPEN TRANSIT." [PCL1/PCM1-M]

The open transition/break-before-make/changeover logic is activated via the "OPEN

TRANSIT." screen input.

In the event of a engine request, a switch is made from mains to generator supply. In order
to achieve this,
• the MCB is opened and
• the GCB is closed.

After the engine request has been reset, a switch is made from generator to mains supply.
In order to achieve this,
• the GCB is opened and
• the MCB is closed.

HB_PCL1/PCM1-M/PCM1-G_09.04_GB 49
2.9.5 CB logic "EXTERNAL"

The external CB logic is activated via the "EXTERNAL" screen input. All switch control must
be carried out via a superordinate controller (e. g. PLC). Closing and opening pulses to the
MCB and the GCB are only output by this control system (PCx) in the "MANUAL" operating
mode. In the event of an alarm, the switches are opened by this control system (PCx) under
all circumstances.

2.10 Emergency power [PCL1/PCM1-M]

Prerequisite The emergency power function can only be activated in the case of synchronous genera-
tors via the "Emergency power ON" screen. Emergency power is carried out in "AUTO-
MATIC" or "TEST" operating mode regardless of the status of the discrete inputs "Auto-
matic 1" and "Automatic 2".

NOTE

If the "Engine enable" or "Engine block" function is assigned to terminal 6, emergency power can be
discretely prevented or interrupted from an external source. Please refer also to the description in
chapter 4.15.3 "Setting the control inputs " on page 135on this.

Activation of emergency power If the mains power reveals an alarm on at least one of terminals 50, 51 or 52 for the
duration of the time set in the "Emergency power delay time ON" input screen, emergency
power is activated. A mains voltage fault is defined as follows: If the mains watchdogs are
switched ON, the limit values set there are used; otherwise, the limits are internally defined
as follows:

Mains watchdogs Voltage Frequency

ON Monitor values Monitor values
OFF UMains < 85 % Urated fMains < 90 % frated
UMains > 112 % Urated fMains > 110 % frated

Emergency power is also triggered via the detection of a switch fault when the MCB is
switched on. In order to achieve this, the "Emergency power" (page 117) and "MCB moni-
toring" screens must be set to "ON" .

The following principles are observed in the case of emergency power:

• If emergency power is triggered, the engine is started under all circumstances, unless the
procedure is interrupted via an alarm or a change in operating mode.
• If the mains returns during starting, the MCB is not opened. The engine starts under all
circumstances, and waits without load until the mains settling time has expired. If a further
mains fault occurs during this time, the MCB is opened, and the GCB is switched to the
black busbar. The engine otherwise shuts off following the double expiry of the mains set-
tling time.
• The GCB is closed regardless of the engine delay time after the black starting limits have
been reached.
• If the mains returns during emergency power (GCB is closed), the mains settling time must
pass before reverse synchronization of the MCB occurs.

Emergency power In the event of active emergency power, the message "Emergency power" is displayed.

50 HB_PCL1/PCM1-M/PCM1-G_09.04_GB
2.10.1 Emergency power with "PARALLEL" CB logic [PCM1-M]

Emergency power Following the recognition of the emergency power case, the emergency power delay time
expires before the engine is started. Once reaching the voltage and frequency limit values,
the MCB is opened, and the GCB is then switched to the black busbar. The genset takes
over the supply of the isolated network.

Return of the mains Following the return of the mains voltage, the item waits until the mains settling time has
expired (0.0..999.9 s, framework: 0.1 seconds, shown in the display), before carrying
out reverse synchronization of the mains power circuit breaker. After closing the mains
power circuit breaker, the genset assumes its original operating mode. If the generator is
shut off, power reduction is carried out provided that the real power controller is activated.

If the mains returns during starting, the mains power circuit breaker is not opened. During
the mains settling time, the genset operates without load, in order to enable the immediate
connection of the GCB in the event of further mains faults.

2.10.2 Emergency power with "OPEN TRANSIT." CB logic

Emergency power Following the recognition of the emergency power case, the emergency power delay time
expires before the engine is started. On reaching the voltage and frequency limit values,
the MCB is opened, and the GCB is then switched to the black busbar. The genset takes
over the supply of the isolated network.

Return of the mains Following the return of the mains voltage, the genset waits until the mains settling time has
expired (0..999 s, framework: 1 seconds, shown in the display), before it switches the
mains power circuit breaker back via a voltage-free ("black") busbar. If, following the expiry
of the mains settling time, an operating request is present, the genset remains in isolated
operation.

If the mains returns during starting, the mains power circuit breaker is not opened. During
the mains settling time, the genset operates without load, in order to enable the immediate
connection of the GCB in the event of further mains faults.

2.10.3 Emergency power with "CLOSED TRANSIT." CB logic

Emergency power Following the recognition of the emergency power case, the emergency power delay time
expires before the engine is started. On reaching the voltage and frequency limit values,
the MCB is opened, and the GCB is then switched to the black busbar. The genset takes
over the supply of the isolated network.

Return of the mains Following the return of the mains voltage, the genset waits until the mains settling time has
expired (0..999 s, framework: 1 seconds, shown in display). If no operating request is
present, reverse synchronization of the MCB is carried out following the expiry of this time.
Following the closure of the mains power circuit breaker, the generator power circuit
breaker is opened immediately and without any reduction in power.

If the mains returns during starting, the mains power circuit breaker is not opened. During
the mains settling time, the genset operates without load, in order to enable the immediate
connection of the GCB in the event of further mains faults.

2.10.4 Emergency power with "INTERCHANGE" CB logic [PCM1-M]

Emergency power Following the recognition of the emergency power case, the emergency power delay time
expires before the engine is started. On reaching the voltage and frequency limit values,
the MCB is opened, and the GCB is then switched to the black busbar. The genset takes
over the supply of the isolated network.

Return of the mains Following the return of the mains voltage, the genset waits until the mains settling time has
expired (0..999 s, framework: 1 seconds, shown in the display). If no operating request is
present, reverse synchronization of the MCB is carried out following the expiry of this time.
Following the closure of the mains power circuit breaker, the generator power circuit
breaker is opened following the reduction in power.

If the mains returns whilst the engine is starting, the mains power circuit breaker is not
opened. During the mains settling time, the genset operates without load, in order to en-
able the immediate connection of the GCB in the event of further mains faults.

2.10.5 Emergency power with "EXTERNAL" CB logic

ATTENTION

Emergency power in accordance with DIN VDE 0108 is not possible in this CB logic!

Emergency power Following the recognition of the emergency power case, the emergency power delay time
expires before the engine is started. On reaching the voltage and frequency limit values,
the MCB is opened, the GCB is not activated. The GCB and the MCB are not otherwise
operated. Not even following the return of the mains.

2.10.6 Emergency power with MCB malfunction

MCB malfunction In the "AUTOMATIC" operating mode without a starting request, the control system is set to
emergency power standby. If the MCB is tripped, the control system attempts to reactivate
this. If this is not possible (due to an MCB alarm), the engine is started following the "MCB
malfunction", if the parameter "Emergency power” is set “ON”. Emergency power subse-
quently supplies the busbar. Only following the successful acknowledgement of the "MCB
malfunction" alarm, is the MCB synchronized and the engine shut off again on expiry of the
mains settling time.

2.11 Sprinkler operation

NOTE

The function "Sprinkler operation" must be assigned to terminal 6. Please refer also to the description in
Chapter 4.15.3 "Setting the control inputs " on page 135 on this issue.

ATTENTION!

Please note that a High signal must be applied at terminal 6 so that no sprinkler operation is carried out.
A Low signal informs the control system that the conditions for sprinkler operation have been met.

! Negative functional logic

Sprinkler "ON" If the signal at terminal 6 drops off, the sprinkler ON command is triggered. The message
"Sprinkler operation" is shown on the display. Up to 6 attempts are made to start the engine
(otherwise 3) if it is not yet in operation. All malfunctions which cause shutoff become mes-
sages. Exception: Terminal 34 or 61 and overspeed. Terminal 34 (alarm input) retains its
set alarm class (if terminal 34 is not present, this is terminal 61). It is advisable to assign the
EMERGENCY OFF here.

NOTE

Via the activation of "Sprinkler operation" (terminal 6), alarm classes F2 and F3 are converted to alarm
class F1 (exception: terminal 34 or 61 and overspeed).

Alarm class F2 and alarm class F3 → alarm class F1

"Sprinkler shutd. F1 active" In the mask "Sprinkler shutd. F1 active" you can choose whether the sprinkler alarm classes
Mains are still active during the sprinkler coasting or if the primary alarm class will be active after
reset of the sprinkler request (terminal 6).
MCB
A distinction is made between three operating conditions:

a)••The engine is stopped:
The engine will be started and the GCB will not be closed.

G M b) The engine runs: The GCB will be opened.

2.) MCB is open

(mains voltage available) and the parameter "Emergency mode” is ON.
a) The GCB will be closed or remains closed.
b) In the event of a generator overload, the GCB will be opened; following the alarm
acknowledgement the GCB will be closed again.

3.) MCB is open

(mains voltage available):
a) The MCB will be synchronized,
b) Following the synchronization of the MCB, the GCB will be opened.

Sprinkler "OFF" Via the completion of the sprinkler input circuit, the sprinkler ON command is withdrawn;
however, sprinkler operation is retained. The message "Sprinkler coasting" appears. Sprin-
kler operation is automatically terminated 10 minutes later. Earlier termination can be
achieved via the "STOP" operating mode. On termination of sprinkler operation, malfunc-
tions which cause shutoffs become active again.

2.13 Analog controller outputs (option ..-A)

As an alternative to a three-position controller output, the item may also be equipped with
an analog controller output. Other configuration masks then appear in configuration mode.
The analog PID controller forms a closed-loop control loop together with the controlled sys-
tem (usually a first-order lag element). The parameters of the PID controller (proportional-
action coefficient KPR, derivative-action time TV and reset time Tn) can be modified individu-
ally. The configuration screens are used for this purpose.

Various values can be obtained from the step response; these are required for adjusting the
controller to its optimum setting:

Rise time Trise Period starting when the value of the control variable leaves a predefined tolerance range
for the control variable following a step in the disturbance variable or reference input vari-
able and ending the first time the value re-enters this range.

Setting time Tsettling Period starting when the value of the control variable leaves a predefined tolerance range
for the control variable following a step in the disturbance variable or reference input vari-
able and ending when the value re-enters this range permanently.

Overshoot xm Highest transient setpoint value deviation during the transition from one steady-state condi-
tion to a new steady-state condition following modification of the disturbance variable or
reference input variable (xm Optimal ≤ 10 %).

System deviation xd Permanent deviation from the final value (PID controller: xd = 0).

By different conversions from these values, the values KPR, Tn and TV can be determined.
Moreover, it is possible, by performing various calculations, to determine the optimal con-
troller settings, e. g. by calculating compensation or adjustment of the time constants, T-sum
rule, symmetric optimum, Bode-diagram. Other setting procedures and information may be
obtained from current literature.

2.13.1 Controller setting

CAUTION!

The following must be observed regarding the controller setting:

• Ensure that the emergency shutdown system is ready for use.
• While determining the critical frequency, pay attention to the amplitude and frequency.
• If the two values change uncontrollably:

! EMERGENCY SHUTDOWN

a.) Initial state

Initial state The start position of the controller is determined using the initial state of the controller. If the
controller is switched off, the basic setting can be used to output a fixed controller position.
If "MANUAL" operating mode has been selected, the initial state signal is output only with
the "START" push-button. Even when the analog controller is switched off, the initial state
can be freely adjusted (e. g. the speed controller can be controlled in a linear manner). On
setting the "STOP" push-button, the analog controller is switched off again.

Initial state Initial state frequency controller 0..100 %

Frequency = 000%
Analog controller output setting with controller switched off. This value is also used as the
initial value.

b.) General settings

The setting rule described below only serves as an example. Whether this method is suit-
able for setting your particular controlled system has not been and cannot be taken into ac-
count as each controlled system behaves uniquely.

There are various methods of setting a controller. The setting rules of Ziegler and Nichols
are explained below (determination for abrupt disturbances on the system input); this setting
method assumes a pure lag element connected in series with a first-order lag system.

1. Controller operated as a P-only controller

(where Tn = ∞ [screen setting: Tn =0], TV = 0).
2. Increase gain KPR (P-gain) until the control loop oscillates continuously at KP = KPkrit.

Attention If the engine starts to oscillate uncontrollably, carry out an emer-

gency shutdown and alter the screen setting accordingly.

3. At the same time: measure the critical cycle duration Tcrit

4. Set the parameters:

PID-controller PI-controller
KPR = 0.6 × KPcrit KPR = 0.45 × KPcrit
Tn = 0.5 × Tcrit Tn = 0.83 × Tcrit
TV = 0.125 × Tcrit

2.14 Load and/or var sharing [PCM1x]

Control guarantees that, in every operating condition (operation in parallel with the mains,
isolated operation in parallel with other gensets or reverse synchronization of the busbar to
the mains), the real power (in reference to the relevant nominal load) is evenly shared over
the gensets operating in parallel to the busbar. Those items that are found in the "Test" or
"Automatic" operating mode are involved in the load or var sharing. Moreover, a start
command has been issued and there are no alarms present that would shut down the sys-
tem.

Operation in parallel with the mains Each controller involved in load/var sharing influences the genset to which it is assigned
with mains interchange control in such a manner that the real power set at the mains interchange point (main control
variable) remains constant. All items are interlinked via a CAN bus, via which any devia-
tion in real power (generator power) can be determined for each genset. This control
variable is taken into consideration on controlling the interchange load. The weighting,
with which the secondary and the main control variable (= "reference variable") are
processed, can be set via a factor. In controlled state, the set real power flows at the
mains interchange point, whereby the total real power is subdivided equally amongst
those gensets involved in distribution control. If a constant power (F..fixed value) has
been entered as the setpoint value for a genset, this genset is no longer involved in
distribution control.

Isolated operation in parallel with Each controller involved in load/var sharing influences the genset to which it is assigned
other gensets in such a manner that the rated frequency (main control variable) which has been set
remains constant. All items are interlinked via a CAN bus, via which any deviation in
real power (generator power) can be determined for each genset. This control variable is
taken into consideration on controlling the frequency. The weighting, with which the
secondary and the main control variable (= "reference variable") are processed, can be
set via a factor. In controlled state, the isolated system has the set rated frequency,
whereby the total real power (in reference to the relevant nominal power) is subdivided
equally amongst those gensets involved in distribution control.

Reverse synchronization of the busbar Distribution is carried out according to the type of isolated operation. However, the set-
to the mains point value for the frequency is formed from the mains frequency (+/-0.1 Hz). The relay
outputs "Command: close GCB" for all items can be switched in parallel.

Prerequisites It is imperative that the rated system frequencies (page 82), the start/stop parameters
(page 100) and the circuit breaker logics (page 110) are set to the same values for all
items involved in distribution control.

58 HB_PCL1/PCM1-M/PCM1-G_09.04_GB
 Description of the interface for distribution Distribution control is based on a multi-master-capable bus between the items. This structure enables
control the parallel operation of up to 8 gensets.

The following must be noted to ensure 1. The maximum bus length must not exceed 250 meters.
trouble-free operation: 2. The bus must be terminated at each end with terminating resistors which correspond to the wave
impedance of the bus cable (approx. 80..120 Ω).
3. The bus must be of a linear structure. Dead-end feeders are not permissible.
4. Screened "Twister-Pairs" are preferable for use as the bus cable (Ex.: Lappkabel Unitronic LIYCY
(TP) 2×2×0.25, UNITRONIC-Bus LD 2×2×0.22).
5. The bus cable must not be routed in the vicinity of heavy current power lines.

2.14.1 Load/var sharing via the CAN bus

Whether, and the manner in which, a genset carries out real power or frequency control in
isolated operation in parallel with other gensets, is defined by the "real power distribution
reference variable." parameter in % in chapter 4.10.6 "Load/var sharing" on page 99 of
this manual. In this case, 10 % means increased real power control, and 99 % increased
frequency control. This parameter must be set individually for each genset.

In the case of the following control system, it must be noted that each item calculates the
mean utilization factor of all items from the data transmitted via the CAN bus, and then
compares this with its own utilization factor. The utilization factor is compared with the ref-
erence variable, and results in the new reference variable. Frequency and real power con-
trol are simultaneously carried out in these items (corresponding to the reference variable).

Frequency control is carried out via the measured voltage/frequency of the voltage system.

2.17.3 Alarm acknowledgement

DANGER!!!

The engine may start unintentionally if an alarm, which caused the engine to shut down, is acknowledged
and an enabling is still present. Before acknowledging the alarm, check the cause of the alarm, in order to
protect operating personnel located in the vicinity of the system against injuries, and to protect the engine
against unintentional destruction.
⇒ If the cause of the alarm is not known or is unclear, NEVER press the acknowledge push-button! The
destruction of the engine cannot otherwise be ruled out !

By pressing the "QUIT" push-button, the output of the centralized alarm and the alarm mes-
sages on the LC display are acknowledged according to the following logic:

NOTE

In order to acknowledge alarm messages via terminal 6, the "acknowledgement" function must be
assigned to this terminal. Please see also the description in chapter "Adjust function of terminal 6" on
page 136.

Horn After 2 minutes the horn is reset regardless of the acknowledgement of an alarm.

Interface All internal errors are conveyed via the interface.

NOTE

By acknowledging the alarms via the interface there is no difference of "short acknowledge" and "long
acknowledge". After 0.1 s it will be "long acknowledged".

a.) Short acknowledgement (< 2.5 s)

Meaning The "QUIT" push-button is pressed for 0.5 s < t < 2.5 s or
the terminal 6 is set for 0.5 s < t < 2.5 s.

Result - The LED "alarm" is continually illuminated.

Lamp test The LED's can be checked via a lamp test. In order to achieve this, the "Setpoint↑" and
"Setpoint↓" push-buttons must be pressed simultaneously.

1 2 3 ........................... LED Voltage control Color "GREEN"

"U L1 .. U L2 .. U L3"
The LED's "UL1", "UL2" and "UL3" show which voltage (UL1N, UL2N, UL3N, UL12, UL23 or UL31) is
currently being displayed. This applies both to the generator and the rated voltage dis-
play.

4 ................................... LED Alarm Color "RED"

"RESET" (Alarm)
If the "RESET" LED illuminates, an alarm is present in the item; this is processed according
to its alarm class. The message and the type of alarm are shown on the LC display. If this
LED flashes, a new alarm has occurred within the last two minutes. Via brief acknowledg-
ment, this switches to continuous illumination, and the centralized alarm (horn) is ceased.

5 ................................... LED Reply: MCB is closed / Mains parallel Color "GREEN"

[PCL1 or PCM1-M] "MCB ON"
[PCM1-G] "Mains parallel" [PCL1 or PCM1-M] Items with two power circuit breakers: The "MCB ON" LED indi-
cates that the mains power circuit breaker is closed.
[PCM1-G].. Items with one power circuit breaker or items which have been made into 1-
CB items via external wiring [see chapter 2.1.2 "... systems with one power
circuit breaker" on page 27): The "Mains parallel" LED indicates that the gen-
set is operating in parallel with the mains.

6 ................................... LED Engine monitoring Color "GREEN"

"Monitoring"
If the "Monitoring" LED is lit, engine monitoring is activated, i. e., in addition to the perma-
nently monitored alarm inputs, the delayed programmed alarm inputs are also monitored.
Generator underspeed, underfrequency, undervoltage and reverse power are also moni-
tored.

7 ................................... LED Reply: GCB is closed Color "GREEN"

"GCB ON"
The "GCB ON" LED signals that the generator power circuit breaker is closed.

8 ................................... LED Operating mode "STOP" Color "RED"

" 0 " (STOP)"
If the LED " 0 " (STOP) is illuminated, the "STOP" mode has been selected. If this LED
flashes, a firing speed is detected in "STOP" mode.

9 ................................... LED Operating mode "AUTOMATIC" Color "YELLOW"

"AUTOMATIC"
If the "AUTOMATIC" LED is lit, the "AUTOMATIC" operating mode is active. The push-
buttons for direct activation of the power circuit breaker and the start / stop push-buttons
are de-activated.

10 ................................. LED Operating mode "MANUAL" Color "YELLOW"

"MANUAL"
If the "MANUAL" LED is lit, the "MANUAL" operating mode is active. The push-buttons for
direct activation of the power circuit breaker and the start / stop push-buttons are de-
activated.

HB_PCL1/PCM1-M/PCM1-G_09.04_GB 69
11 ................................. LED Phase position/synchroscope Colors "RED/YELLOW/GREEN"
"-10%..fN..+10%"
Normal operation ......The LED's between -10 % and +10 % serve to visualize the gen-
erator frequency. The rated frequency (fN) is entered in the "gen-
erator rated frequency" screen. If the frequency is greater than
+10 % or less than -10 %, the corresponding outer LED flashes
LED.
Configuration ............If, in configuration mode, the service display is "ON" and the
double voltage/double frequency display is active, the LED's
show the current phase angle between the two displayed volt-
ages. The green LED in the center of the 15 LED's indicates that
the measured phase angle between the voltage systems dis-
played is less than 12 ° electrical. The phase angle is only dis-
played if the frequencies of the two voltages are within the fol-
lowing permissible ranges:

Generator............................. 88..112 % fN
Mains .................................. 96..104 % fN

A distinction is made between two directions of rotation:

-10 % → +10 %
On running the LED's from left to right, the genera-
tor frequency is too high, i. e., the generator is
turning too fast;
+10 % → -10 %
On running the LED's from right to left, the genera-
tor frequency is too low, i. e., the generator is
turning too slowly.

3.3 Push-buttons

3.3.1 Display touch

In order to facilitate the setting of the parameters, the push-buttons have an AUTOROLL func-
tion. It allows to switch to the next setting and configuration screens, the digits, or the cursor
position. The AUTOROLL function will only be activated when the user depresses the corre-
sponding keys for a certain period of time.

with the "Setpoint +" or "Setpoint −" push-buttons. Certain setpoint val-
ues, which are entered into the item from external sources, can only
be viewed.
Configuration ........"PARAMETER" - This push-button is used to move the cursor one posi-
tion to the right. When the last right-hand position is reached, the
cursor automatically moves to the first position left-hand of the value to
be entered.

DANGER!!!

The engine may start unintentionally if an alarm, which caused the engine to shut down, is acknowledged
and an enabling is still present. Before acknowledging the alarm, check the cause of the alarm, in order to
protect operating personnel located in the vicinity of the system against injuries, and to protect the engine
against unintentional destruction.

HB_PCL1/PCM1-M/PCM1-G_09.04_GB 73
3.4 Display

28 .......................... DISPLAY LC display

"LC display"
The LC display shows messages and values, depending on the respective mode applied.
In configuration mode, the individual parameters are displayed and changed. In Auto-
matic mode the operating variables (e. g. voltages and currents) can be called up.

Top line • In the "V/kV" field, the generator voltage is displayed depending on the LED's UL1, UL2
and UL3.
• In the fields "A(L1)", "A(L2)" and "A(L3)" the generator line currents are displayed sepa-
rately for each phase.

Bottom line The following screens appear in the "operating and alarm messages" field:

Basic screen
• Display of the generator power factor ϕ and the generator actual real power
or
• the action of the genset that is currently being carried out (synchronization, starting,
etc.)

Subordinate screens: Depending on the item's equipment,

• the engine speed,
• the mains voltage,
• [PCM1x] the mains current/the mains power, mains power factor ϕ,
• the analog input variables,
• the generator's active energy,
• the generator re-active power (is determined via the current of phase L1; also if "three-
phase" power measurement was selected),
• the operating hours,
• the time remaining until the next maintenance call,
• the engine start counter,
• the battery voltage (supply voltage),
• [PCM1x] the number of subscribers participating in load sharing,
• the maximum generator current (slave pointer),
• the four alarm messages which occurred first and
• [PCM1x] the time/the date
are displayed.

These display screens are displayed in succession by pressing the "STATUS / ALARM"
push-button. When the last display screen has been reached, the basic screen is dis-
played. If alarms have occurred, their message texts are displayed in the sequence of their
occurrence in the display screens before the basic screen. If item functions are active (e. g.
synchronization of the GCB), the basic screen is superimposed with the corresponding
message (e. g. "synchronization"). Following the termination of the item function, the basic
screen is displayed again.

74 HB_PCL1/PCM1-M/PCM1-G_09.04_GB
4 Configuration screens (input of the parameters)
Configuration can be performed using a PC and the PC program FL-SOFT3 via the serial interface or via the front panel push-buttons
and the front panel LC display. Additionally it is possible to configure the unit via CAN bus. The following Baudrate are therefore
usable:

• Configuration via direct configuration plug = 9,600 Baud (8 Bit, no parity, 1 Stoppbit) and
• CAN bus (CiA) = 125, 250 or 500 kBaud configurable via the serial interface.

CAUTION

For configuration of this control (firmware software version starting with 4.1xxx) a PC software with the
following version number:

FL-SOFT3 ab 3.0.015
Because of functional enhancements within the controls of the PCx Series it is necessary (beginning with firmware version 4.1.xxx of
the PCx) to use a newer version of the configuration software FL-SOFT3. This version at least has to be 3.0.015 or higher.

Once you successfully finished the installation older project files still can be used.

WARNING

Please note that configuration only should be performed in a standstill of the system.

NOTE

Please take into account the list of parameters at the end of this manual.

The configuration screens, if they are in input mode (simultaneously pressing of "U SELECT"
and "PARAMETER"), can be scrolled via "STATUS / ALARM". If the "STATUS / ALARM"
push-button is pressed for a longer period of time, the scroll function will be activated, and
the screens will be browsed rapidly. Simultaneously pressing the "STATUS / ALARM" and
"PARAMETER" push-buttons allows you to scroll through the last four configuration screens.
(exception: change from the first to the last parameter as well as backwards in the service
screen is not possible). If no entry, modification or any other action is carried out for
60 seconds, the item automatically returns to the automatic mode.

NOTE

There are two different types of hardware, which are described in this manual: A 100 Vac version [1]
and a 400 Vac version [4]. The configuration screens and parameters differ in both versions, and the
setting limits also differ. The two types are identified by the preceding voltage values ([1] ... or [4] ...).

WARNING!

By loading the standard values all parameters are overwritten. Thereby the customer settings get lost and
shall be saved necessarily by FL-SOFT3.

Procedure:

• Enter code level 2.

• Select "operation mode STOP"
• Press the 3 buttons "U SELECT", "PARAMETER" and "STATUS / ALARM" for at least
5 seconds at the same time.
• Message "Default Values loading 000%" is displayed.
• Wait until value reaches 100%.

4.3 Password protection

The item is equipped with a three-level code and configuration hierarchy, which enables it
to visualize various configuration screens for different users. A distinction is made between:

Code level 0 User: Third party

(CS0) This code level enables no access whatsoever to the parameters. The configuration is
blocked.

Code level 1 User: Customer

(CS1) This code level entitles the user to change a few selected parameters (e. g. rated real
power, etc.). Changing a password is not possible in this case.

Code level 2 User: Commissioner

(CS2) With code level 2 the user acquires all access rights, and therefore has direct access to all
parameters (displaying and changing). In addition, the user may also set the password for
levels 1 and 2 in this level.

NOTE

Once the code level is set, this is not changed, even if the configuration mode is accessed steady. When
an incorrect code number is entered, the code level is set to CS0 and the item is therefore locked for
external users (set of password on page 86). Two hours after the final operation of the item, code level
CS0 is automatically set. By inputting the corresponding code number, the corresponding level is
accessed again.

out being changed, the item's code level remains as it was. Two four-digit code numbers
(0000..9999) exist for changing the code level and setting up new code words for the
users. No assignment is required for the "third party" user level, as the user does not usually
receive access to the configuration level (protected via the code).

4.4 Direct configuration

NOTE

To carry out direct configuration, you require a direct configuration cable, the PC program (supplied with
the cable) and the corresponding configuration files. Please consult the online help installed when the
program is installed for a description of the PC program and its setup.

Remote configuration For remote configuration, the password of level 2 must be entered via the parameter
"password level 2", otherwise, the values can only be read but not written. Inputting via the
bus has no influence on the displayed screen; this means, if the item itself is in code
level 0, it also behaves as described in the previous section; only configuration via the bus
is permissible. The isolation for the configuration via the bus is valid for 10 minutes from the
point in time at which configuration or readout has not occurred; afterwards, the password
must be configured again. The password must also be entered in advance to load the lan-
guage. If the code for level 2 is entered on the item itself, the configuration is automatically
isolated via the bus.

WARNING !

If the following parameter "direct para." is set to "YES", communication via the interface with terminals
X1..X5 is locked. If communication is to be re-established via interface X1..X5 after configurating the item
(e. g. CAN bus connection via a Gateway), the following parameter must be set to "NO"!
Direct configuration is switched off for safety reasons once the firing speed has been reached. That means
that further setting of the item parameters is only possible using the display and push-buttons, directly or via
the CAN bus interface. The screen is switched from YES to NO (this is done using the software). The de-
activation of the direct configuration is for safety reasons, so that in the case of multiple systems starting
simultaneously (e. g. emergency power situation) a simultaneous switching of the generator switches to the
black busbar is prevented.

Direct para. Direct configuration YES/NO

YES
YES .......... A configuration via the lateral plug is possible, and any CAN bus connection
that may be available via terminals X1..X5 is de-activated. The following con-
ditions must be met in order to carry out configuration via the lateral plug:
- A connection must be established via the direct configuration cable between
the item and the PC,
- the baud rate of the FL-Soft3 program must be set to 9,600 Baud and
- the corresponding configuration file must be used (file name: "xxxx-xxxx-yyy-
zz.asm", initiated by xxxx-xxxx-yyy-zz.cfg).
NO .......... Configuration via the lateral plug cannot be carried out, and any available
CAN bus connection via the terminals X1..X5 is activated.

4.5 Generator number

Generator number Generator/item number 1..8

0
If several generators are available and these are coupled via a can bus, a different num-
ber must be assigned to each generator for differentiation purposes. The generator num-
ber 1 should be assigned even in the case of individual items. The generator number en-
tered here corresponds to the genset number in the program.

The input of the current conversion ratio is necessary in order to display and control the ac-
tual values. The ratio must be selected in such a manner that, at maximum power, at least
60 % of the converter's nominal current flows. A lower percentage may lead to malfunc-
tions. Additional inaccuracies in the control and monitoring functions also occur.

{X} / 1 A... Secondary current = 1 A at primary rated current = {X} A;

{X} / 5 A... Secondary rated current = 5 A at primary rated current = {X} A;
{X}............ e.g. from the main series 10, 15, 20, 30, 50 or 75 A and the decimal frac-
tions and multiples of these or the corresponding secondary series with 25,
40 or 60 A.

Power measuring Generator power measurement singlephase/threephase

gen.
With regard to the measurement of generator power, single-phase or three-phase meas-
urement may be selected. If "single-phase power measurement" is set, the current and the
voltage in phase L1 are used for power measurement. If "three-phase power measurement"
is set, all three currents and the relevant voltages are used for power measurement.
• single phase power measurement: P = 3 ⋅ UL12 ⋅ IL1 ⋅ cos ϕ .
• three phase power measurement:
P = UL1N × IL1 × cosϕ + UL2N × IL2 × cosϕ + UL3N × IL3 × cosϕ.

4.9.3 Mains Current/Mains Power Measurement

a.) Mains power actual value measurement via analog input (only PCM1-..H-..)
Measurement of the mains power actual value measurement via an analog input T{x} [x = 1-7] is possible if at least one of the ana-
log inputs T{x} [x = 1-7] is a 0/4-20 input. Selection of the analog input occurs via the following parameters.

Analog in Pmains Analog input P-mains: Selection OFF/T{x}

OFF
OFF ........................... The mains interchange (import/export) real power actual value is
only PCM1-..H-.. calculated out of the measured mains current and the measured
mains voltage. The analog inputs can either be used as real
power setpoint value or as free configurable alarm inputs. The
following masks of this function are not displayed.
T{x}............................ The mains interchange (import/export) real power actual value
can be fed to the control by a measuring transducer and can be
measured via the configured free scalable 0/4-20 mA input T{x}
({x} = 1-7) (other types of analog inputs cannot be used).The fol-
lowing masks of this function are displayed.

Note
Please note that the selected analog input T{x}
• has to be configured to OFF in chapter "Analog inputs" and that this analog input
• must not be configured as generator real power setpoint value in chapter
"Controller".
• T{x}: Dependent on the control model these analog inputs are included and possibly
built as 0/4-20 mA type. For this function only 0/4-20 mA inputs can be used
(only these inputs are displayed for selection at this parameter).
• A change of the function of the analog inputs is updated in the visualization of
FL-CABLE-RS232 once the PC program has been restarted after the dynamic
configuration has been started.

Priority of the functions of the analog inputs

The following priority is valid if more than one function has been assigned to a analog in-
put:
• Highest priority: Mains interchange (import/export) real power actual value
• Middle priority: Generator real power setpoint value
• Lowest priority: Measuring input as common analog value

Analog in Pmains Analog input P mains: Range 0-20 mA/4-20 mA

0-00mA
The measuring range 0-20 mA or 4-20 mA is selected with this parameter. If the range
only PCM1-..H-.. was selected 4-20 mA and the current is lower than 2 mA, a wire break alarm is issued.

Note
It is possible to adjust the display range of the mains interchange (import/export) real
power actual value. Thereto the wanted value must be entered and saved using the pa-
rameter "name and unit" of the selected analog input (see chapter "Analog inputs").

NOTE

In case of an import/export real power control you have to take care that the setpoint value is set in the
middle of the measuring range. By this setting the controller dynamic can be used to full capacity.

The input of the current conversion ratio is necessary in order to display and control the ac-
[PCM1x] tual values. The ratio must be selected in such a manner that, at maximum power, at least
60 % of the converter's nominal current flow. A lower percentage may lead to malfunc-
tions. Additional inaccuracies in the control and monitoring functions also occur.

PCN4 modus PCN4 modus ON/OFF

ON
ON ........................... The PCM is operating in PCN4mode. The control PCM expects
only PCM1-G-..-E-.. CAN bus messages from the PCN4 and reacts accordingly. Ad-
ditionally the control PCM transmits messages to the PCN4.
OFF ........................... The control PCM operates without PCN4 functionality as a nor-
mal genset control.

Rated power in Rated power in the system 0..16,000 kW

The PCN4 transmits the current mains interchange real power in percent related to the
only PCM1-G-..-E-.. rated power in the system to the controller PCM.

Note
This configuration is valid only if parameter " PCN4 modus" is configured to ON.

ATTENTION
Since the PCN4is only able to transmit a percentage value related to the rated value it is
absolutely necessary to configure the rated power in all units (PCN4 and PCM; in the
PCM) to the same value.

ON
ON .......... In operation in parallel with the mains a load independent automatic control
of the power factor ϕ is carried out. In the case of excessively low currents
(secondary current less than 5 % IN) the power factor can only be measured
very inaccurately. In order to avoid power swings, the controller is automati-
cally locked in such cases. The subsequent screens of this option are dis-
played.

The amount of the re-active power is controlled in such a manner that, when regulated, this
results in the pre-specified power factor ϕ. The designations "i" and "c" stand for inductive
(generator overexcited) and capacitive (generator underexcited) re-active power. This set-
point is active in operation in parallel with the mains.

NOTE

Please note the settings for the voltage controller in chapter "Voltage controller". The settings there for the
voltage controller also influence the cos ϕ controller.

trolled in such a manner that, in its regulated state, the actual value deviates from the inter-
nally calculated setpoint (setpoint 1) percentage value of the insensitivity setting at most. In
this case, the percentage value refers to the generator rated power.

justed to the pre-selected setpoint (page 88/96) when the real power control-
ler is switched on. The subsequent screens of this option are displayed.
OFF .......... Control is not carried out, and the subsequent screens of this option are not
displayed.

Power controller Real power controller setpoint ramp 0..100 %/s

ramp 000%/s
The setpoint change is supplied to the controller via a ramp in percent per second in ref-
erence to the generator rated power (see page 84). The slope of the ramp is used to alter
the rate at which the controller modifies the setpoint value. The more rapidly the change in
the setpoint is to be carried out, the greater this value has to be.

a.) Power limitation

Power limit Real power controller maximum power limitation 10..120 %

P max. 000%
If the maximum real generator load is to be limited, a percentage, based on the rated
generator power (see page 84), will be entered into this screen, in accordance with the
specified setting limits. The controller adjusts the genset in such a manner that this value is
not exceeded. The value "Pmax" only limits the setpoint of the real power controller, and is
without significance in isolated operation.

Power limit Real power controller minimum power limitation 0..50 %

P min. 00%
If the maximum real generator load is to be limited, a percentage, based on the rated
generator power (see page 84), will be entered into this screen, in accordance with the
specified setting limits. The controller adjusts the genset in such a manner that no negative
deviation from this value occurs. This parameter is ignored in the case of fixed-setpoint
control or in isolated operation.

b.) External setpoint value
The generator real power setpoint value via an analog input T{x} [x = 1-7] is possible at the time when minimum one of the analog
inputs T{x} [x = 1-7] is carried out as 0/4-20 mA input. The selection of the analog input is done using the following parameters.

Power setpoint P setpoint value: external setpoint value OFF/T{x}

external OFF
OFF .......... If this parameter is configured to "OFF" a generator real power setpoint value
can not be fed via the 0/4-20 mA input to the control. The analog inputs can
be used either as mains interchange (import/export) real power actual value
or as free configurable alarm inputs. In case of selection of terminal 5 the in-
ternal setpoint value 2 "Pset2" is used as setpoint value. The subsequent screens
of this function are not displayed.
T{x}........... The generator real power setpoint value can be fed to the control via an ex-
ternal signal using the 0/4-20 mA inputs (T{x}, {x) = 1-7; other types of ana-
log inputs cannot be used). This setpoint value is used when automatic 2 (ter-
minal 5) is set. The subsequent screens of this function are displayed.

Note
Please note that the selected analog input T{x}
• has to be configured to OFF in chapter "Analog inputs" and
• must not be configured as mains interchange real power actual value in chapter
"Measuring".
• T{x}: Dependent on the configuration of the control these analog inputs are included
and possibly a 0/4-20 mA type. For this function only 0/4-20 mA analog inputs can be
used.
• A change of the function of the analog inputs is updated in the visualization of FL-
CABLE-RS232 once the PC program has been restarted after the dynamic configuration
has been started.

Priority of the functions of the analog inputs

The following priority is valid if more than one function has been assigned to a analog in-
put:
• Highest priority: Mains interchange real power actual value measurement
• Middle priority: Real power setpoint value
• Lowest priority: Measuring input as common analog value

Analog input Real power setpoint value specification analog input 0-20 / 4-20 mA
0-00mA
The analog input of the real power controller (terminals 93, 94 and 95 - see wiring dia-
gram; in exceptional cases, the setpoint is applied to terminals 91 and 92) can be
switched here between 0-20 mA and 4-20 mA depending on the setpoint source.
0-20 mA ... Minimum value of the setpoint at 0 mA; maximum value at 20 mA.
4-20 mA ... Minimum value of the setpoint at 4 mA; maximum value at 20 mA.

CAUTION!

The interchange power setpoint (import/export power)can also be scaled. When controlling interchange
power, it is vital to ensure that no F power is entered simultaneously with I or E power when scaling the
external analog input.

Power controller Real power controller insensitivity 0.1..25.0 %

dead band 00.0%
In operation in parallel with the mains, the real power is controlled in such a manner that,
in its regulated state, the actual value deviates from the real power setpoint by the per-
centage value of the sensitivity setting at the most. In this case, the percentage value refers
to the generator rated power (see page 84).

Power controller Real power controller gain factor 0.1..99.9

gain Kp 00.0
The gain factor Kp influences the operating time of the relays. By increasing the factor, the
operating time can be increased in the event of a certain control deviation.

Powercontr. dead Real power controller insensitivity reduction 1.0..9.9

band ratio *0.0
If, following the adjustment of the controller, no further adjusting pulse has been output for
at least 5 s, the insensitivity is reduced by the input factor.
For example: In the case of an insensitivity of 2.5 % and a factor of 2.0 the insensitivity is increased
after 5 s to 5.0 %. If the control deviation subsequently exceeds 5.0 %, again, the controller's original
sensitivity is automatically reset (2.5 %). This input can be used, in the event of small control devia-
tions, to avoid unnecessarily frequent actuation processes, thereby protecting the adjustment facility.

Definition "Primary control variable"

• Isolated operation = frequency
• Mains parallel operation = real power (at the mains interchange point)

Definition "Secondary control variable"

• Isolated operation = real power related to the other generators
• Mains parallel operation = real power related to the other generators

not displayed.

React.load share var sharing reference variable 10..99 %

factor 00%
Increasing the weighting factor increases the influence of the primary control variable (the
voltage) to the control. The smaller the factor which is configured, the greater the influence
of the secondary control variable (generator reactive power). Var sharing is activated dur-
ing isolated parallel operating only.

are therefore skipped.
4.11.1 Load-dependent start/stop in operation in parallel

NOTE

Please be aware that load sharing must remain configured to "ON", regardless of whether an additional
generator is available for a load sharing, in order to enable a automatic start/stop to be carried out .

NOTE

To carry out an automatic start/stop of the engine, all participating controls have to be configured with
the identical rated power.

ON .......... If this mask is active, and the control input "Automatic 1" is connected to termi-
nal 3, an automatic start/stop operation is carried out on the basis of the
generator setpoint power 1 (see page 88). If terminal 5 is simultaneously
connected 3 has priority.
OFF .......... No automatic start/stop operation is carried out; the adjustment of the pre-
specified setpoint value is carried out under all circumstances.

nal 5, an automatic start/stop operation is carried out on the basis of the
generator setpoint power 2 (see page 88). If terminal 3 is simultaneously
connected, terminal 3 has priority.

a.) Single genset in operation in parallel with the mains
The load-dependent start/stop function is activated when
• the "AUTOMATIC" mode has been selected and
• interchange power control (import/export power) has been activated by one of the two
discrete inputs ("Automatic 1" or "Automatic 2") (" I " or " E " power) and
• one or both input screens "Load-dependent stop/start on terminal 3/5" has been set to
"ON".
Minimum load Generator minimum setpoint power 0..6,900 kW
generator 0000kW
Interchange real power control (import/export power) requires a generator setpoint power
value. In many cases, starting the engine is only sensible after reaching a certain genera-
tor setpoint power value, in order therefore to operate the genset with a reasonable de-
gree of efficiency. For example, at least 40 kW of real power must be supplied by the
genset in order for it to start.

Add-on delay Start delay for load-dependent start/stop 0..999 s

mains oper. 000s
Starting may be delayed even if the generator start power has been reached. In order to
avoid starting the engine in the event of short-term load switch-ons, a start delay time may
be input here in seconds. The start power must therefore be present without interruption
during this period of time, in order to ensure that the engine is started.

Shed-off delay Stop delay for load-dependent start/stop 0..999 s

mains oper. 000s
Stopping can be delayed even if the generator stop power has been reached. In order to
avoid switching the engine off in the event of short-term load interruptions, a stop delay
time may be input here in seconds. The stop power must therefore be present without inter-
ruption during this period of time, in order to ensure that the engine is stopped.

b.) Stopping hysteresis

NOTE

The following screen is used to determine stopping hysteresis for single gensets in operation in parallel with
the mains, for gensets connected to other gensets in operation in parallel with the mains and in isolated
operation in parallel with other gensets. However, the screen appears only once at this point.

Hysteresis add-. Hysteresis of load-dependent start/stop 0..9,999 kW

on/off op.0000kW
The stop power of the genset is determined via hysteresis. Hysteresis is used to prevent the
engine continuously starting and shutting down again.

HB_PCL1/PCM1-M/PCM1-G_09.04_GB 101
c.) Operation in parallel with the mains (interchange power control with one genset)
The following generally applies:

Case 1: Engine start If [PNT.setpoint - PNT.actual > Pstart] the engine starts. (a)

Case 2: Engine stop If [PNT.setpoint - PNT.actual + PGN.actual.tot < Pstart - PHyst] the engine stops. (b)

Example The power supplied by the mains, which is to be adjusted, is 50 kW. This value is entered
into the setpoint value screen (see chapter "Controller") as "I0050kW". The generator
should be operated with at least 30 kW.

PNT.setpoint= -50 kW....... Incoming/import power must be entered as a negative number,

output/export power as a positive number.
Pstart= 30 kW ............ The minimum power requested by the genset.
PHyst = 10 kW ........... The power hysteresis for stopping.

When inserted into the above mentioned formulae, this means:

Example for case 1 The engine starts with the following incoming mains power: If formula (a) is inverted, this
results in

[PNT.actual < PNT.setpoint - Pstart] ⇒ PNT.actual< - 50 kW - 30 kW = -80 kW ⇒ "B0080 kW".

The power supplied by the mains must be at least 80 kW in order for the engine to start.
This is then operated with a minimum power of 30 kW.

Example for case 2 The engine stops if it has to output less than the minimum power minus hysteresis. This is the
case with the following generator power: If formula (b) is inverted, this results in

[PGN.actual = stop power genset < - PNT.setpoint+ PNT.actual + Pstart - Physt].

[PGN.actual < - 50 kW + 50 kW + 30 kW - 10 kW = 20 kW.

If the generator falls below its minimum power minus hysteresis, it is stopped. The power
incoming from the mains therefore remains at the value which is to be controlled until just
prior to stopping. Following stopping, the power supplied by the mains increases to
70 kW.

102 HB_PCL1/PCM1-M/PCM1-G_09.04_GB
d.) Interconnection with other gensets in operation in parallel with the mains
The load-dependent start/stop function is activated when, for every genset,
• the "AUTOMATIC" mode has been selected and
• interchange power control (import/export power) has been activated by one of the two
discrete inputs ("Automatic 1" or "Automatic 2") (" E "- or " I " power) and
• all inputs, such as start/stop power, start/stop delays, selected setpoint values are
identical for all gensets involved and
• one or both input screens "Load-dependent stop/start on terminal 3/5" has been set to
"ON" and
• the input screens "Load sharing" or. "var sharing" have been set to "ON" and
• the same rated power is available to all gensets.

NOTE

The following parameter only becomes effective if another engine is to be started in operation in parallel
with the mains. The first engine is started as described under individual operation on the basis of minimum
generator power.

Reserve power Reserve power for load-dependent start/stop (mains) 0..9,999 kW

mains op. 0000kW
The starting of an additional engine is determined via the reserve power. The reserve
power results from the currently available total generator rated real power (generator
rated real power × number of closed generator power circuit breakers) and the current to-
tal generator actual real power. If the current total generator real power is deducted from
the currently available total generator rated real power, this results in the system's reserve
power. If negative deviation from this reserve power occurs, the next engine is started.

Total generator rated real power

- Total currently available generator actual real power

= Reserve power

Priority of Priority of gensets 0..14

generators 00
This priority specifies the sequence in which the individual engines are started. The item for
which the smallest number was set has the highest priority. This engine is the first to be
started and the last to be stopped. In the event of identical priorities, the starting sequence
is determined by the operating hours. In this case, the engine with fewer operating hours
takes priority. In the event of the same number of operating hours, the engine with the
smaller item number is permitted to start.

HB_PCL1/PCM1-M/PCM1-G_09.04_GB 103
e.) Operation in parallel with the mains (interchange power control with several gensets)
The following generally applies:

Case 3: Start first genset. There is still no GCB connected in the group.

If [PNT.setpoint - PNT.actual > Pstart] the first engine starts. (c)

Case 4: Starting additional gensets. At least one GCB in the group is closed.

If [PGN.actual.tot + Preserve.parallel > Prated.tot] the next engine starts. (d)

Case 5: Stoping At least two GCBs in the group are closed.

If [PGN.act.tot + Preserve.parallel + Physt + Prated < Prated.tot] a engine stops. (e)

Case 6: Stoping last genset Only one more GCBs in the group are closed.

If PNT.setpoint - PNT.actual + PGN.actual.tot < Pstart - Physt] the last engine stops.

Example The real power supplied by the mains, which is to be adjusted, is 0 kW. This value is
entered into the setpoint value screen (see chapter "Controllers") as "B0000kW" (corre-
sponds to "L0000kW"). The reserve power in the system should be 40 kW. The power hys-
teresis should be 20 kW. Three gensets are to be operated within the group. he rated
power of a genset is 200 kW. The minimum power of a genset should be 30 kW.

PRated= 200 kW ......... Rated power of a genset.

PRated.tot ...................... Total of the rated power values of the gensets with closed GCB's.
PStart.tot = 30 kW ........ Minimum power of a genset.
PNT.actual ..................... Current mains power.
PNT.setpoint = B0000 kW . setpoint mains power
PReserve.Parallel = 40 kW.... reserve power in operation in parallel with the mains
PHyst = 20 kW ........... power hysteresis
No. GCB ................ number of closed power circuit breakers

Example for Case 3 Power supplied by the mains, with which the first engine is started:

PNT.actual < PNT.setpoint - Pstart.gen.

PNT.actual < 0 kW - 30 kW = -30 kW ⇒ B0030 kW.

The power supplied by the mains must be at least 30 kW in order for the first engine to
start. This is then operated with a minimum power of 30 kW.

Example for Case 4 Generator real power, at which the second engine is started:

PGN.actual > Prated.tot - (PReserve.Parallel / No. GCB).

PGN.actual > 200 kW – (40 kW / 1) = 160 kW.

If the generator real power exceeds 160 kW, negative deviation from the pre-specified re-
serve power has occurred. As a result of this, the next engine is started.

104 HB_PCL1/PCM1-M/PCM1-G_09.04_GB
 Example for Case 4 Generator real power of each individual genset, at which the third engine is started:

PGN.actual > Prated.tot - (Preserve.parallel / No. GCB) - Prated.

PGN.actual. > 400 kW – (40 kW / 2) - 200 kW = 180 kW.

If the generator real power of both gensets exceeds 360 kW (each genset supplies more
than 180 kW), negative deviation from the pre-specified reserve power has occurred. As a
result of this, the next engine is started.

Example for Case 5 Generator real power of each individual genset, at which one genset is stopped:

PGN.actual.tot < Prated.tot - Preserve.parallel - Prated - Physt.

PGN.actual.tot < 600 kW - 40 kW - 200 kW - 20 kW = 340 kW.
(PGN.actual < PGN.actual.tot ) / No. GCB = 340 kW / 3 = 113.3 kW.

If the generator real power of the three gensets falls below 340 kW (each individual gen-
set below 113.3 kW), one engine is stopped. After one engine has been stopped, the in-
put reserve power is still available.

Example for Case 5 Generator real power of each individual genset, at which one of the two engines is
stopped:

PGN.actual.tot < Prated.tot - Preserve.parallel - Prated - Physt.

PGN.actual.tot < 400 kW - 40 kW - 200 kW - 20 kW = 140 kW.
(PGN.actual < PGN.actual.tot) / No. GCB = 140 kW / 2 = 70 kW.

If the generator real power of the two gensets falls below 140 kW (each individual genset
below 70 kW), one engine is stopped. After the engine has been stopped, the input re-
serve power is still available.

Example for Case 6 Generator real power, at which the last engine is stopped:

PGN.actual < - PNT.setpoint + PNT.actual + Pstart.gen - Physt.

PGN.actual. < - 0 kW + 0 kW + 30 kW - 20 kW = 10 kW.

If the generator falls below its minimum real power minus hysteresis, the engine is stopped.
The power incoming from the mains therefore remains at the value which is to be controlled
until just prior to stopping. Following stopping, the power supplied by the mains increases
to 10 kW.

f.) Isolated operation

The load-dependent start/stop function is activated when, for every genset
• the "AUTOMATIC" mode has been selected and
• all inputs, such as start/stop power, start/stop delays, frequency setpoint values are
identical for all gensets involved and
• one or both input screens "Load-dependent stop/start on terminal 3/5" has been set to
"ON" and
• the input screens "Load sharing" or "var sharing" have been set to "ON" and
• the same rated power is available to all gensets.

HB_PCL1/PCM1-M/PCM1-G_09.04_GB 105
 Reserve power Reserve power for load-dependent start/stop (isol. op.) 0..9,999 kW
isol.op. 0000kW
Starting of an additional engine is determined via the reserve power. The reserve power
results from the currently available total generator rated real power (generator rated real
power × number of closed generator power circuit breakers) and the current total genera-
tor actual real power. If the current total generator real power is deducted from the cur-
rently available total generator rated real power, this results in the system's reserve power.
If negative deviation from this reserve power occurs, the next engine is started.

Total generator rated real power

- Total currently available generator actual real power

= Reserve power

NOTE

The reserve power should be selected in such a manner that the expected load surges can be covered by
the genset.

Add-on delay Start delay for load-dependent start/stop 0..999 s

isol.op. 000s
Starting may be delayed even if the engine's start power has been reached. In order to
avoid starting the engine in the event of short-term load switch-ons, a start delay time may
be input in seconds. The start power must therefore be present without interruption during
this period of time, in order to ensure that the engine is started.

Shed-off delay Stop delay for load-dependent start/stop 0..999 s

isol.op. 000s
Stopping can be delayed even if the engine's stop power has been reached. In order to
avoid switching the engine off in the event of short-term load interruptions, a stop delay
time may be input in seconds. The stop power must therefore be present without interrup-
tion during this period of time, in order to ensure that the engine is stopped.

The following generally applies:

Case 7: Engine start If [PGN.actual.tot + Preserve.isolated + > Prated.tot] the engine starts. (f)

Case 8: Engine stop If [PGN.actual.tot + Preserve.isolated + Physt + Prated + < Prated.tot] the engine stops.

Example Two gensets are used in isolated operation in parallel with other gensets. One genset
should always be in operation.

Prated = 200 kW ........ Rated real power of a genset.

PReserve.isolated= 60 kW
Physt = 30 kW

Example for Case 8 Generator real power, at which the second engine is started:

PGN.actual > Prated.tot - Preserve.isolated.

PGN.actual > 200 kW - 60 kW = 140 kW.

If the generator real power exceeds 140 kW negative deviation from the pre-specified
minimum reserve power occurs. As a result of this, the next engine is started.

106 HB_PCL1/PCM1-M/PCM1-G_09.04_GB
 Example for Case 9 Generator real power, at which the second engine is stopped:

PGN.actual.tot < Prated.tot - Preserve.isolated - Prated - Physt.

PGN.actual.tot < 400 kW - 60 kW - 200 kW - 30 kW = 110 kW.
PGN.actual < PGN.actual.tot / No. GCB = 110 kW / 2 = 55 kW.

If, in the case of outgoing isolated load, the total actual generator real power is reduced to
such an extent that one genset is sufficient to ensure the reserve power, the second engine
is stopped.

exceeds the threshold value within this period of time, calculation of the time is re-started
(this delay time applies both to switching on and switching off).

4.11.6 Power circuit breaker logic

NOTE

You can change between two breaker logics via the discrete input "Breaker logic via discrete input"
(description on page 132). The desired standard breaker logic is configured via the following mask. If the
discrete input terminal 62 is configured to "Control input" (parameter is ON) and if is there is a signal to
the terminal the described breaker logic is used (see chapter 4.15.3 “Setting the control inputs” at
page 135). If the signal is reset, the breaker logic of the following mask is valid again. Therefore it is
possible during the operation i.e. to change between the breaker logic "PARALLEL" (automatic
synchronizing) and "EXTERNAL" (manual synchronizing).

The item automatically controls the two power circuit breakers (MCB and GCB). In this
Breaker logic:
case, up to five control functions (modes) may be selected. These are: EXTERNAL, PARAL-
PARALLEL

4.13.10 Mains frequency monitoring [PCM1x]

Monitoring the mains frequency is absolutely vital if a generator is operated within a public
network. In the event of mains failure (e. g. short interruption) the generator which is operat-
ing in parallel with the mains must be automatically disconnected from the mains. Decoup-
ling from the mains is only activated when both power circuit breakers (mains and genera-
tor power circuit breaker) are closed.

The here fixed limit values are used for assessment of the emergency power operation in
case that the following protective items are switched to "ON". On the basis of the here
fixed limit values it is defined whether mains is present or not. The tripping times will not be
noticed.

Function "Mains frequency not within the permissible range"

The mains frequency lies outside of the limit values set for overfrequency or underfrequency.
The power circuit breaker, which is to carry out decoupling from the mains, is immediately
opened. The prerequisite of mains frequency monitoring is operation in parallel with the
mains (both power circuit breakers closed). The malfunction message "Mains overfreq." or
"Mains underfreq" appears. Output via an alarm relay is always possible.

4.13.12 Phase/vector shift monitoring [PCM1x]

Function A phase/vector shift is a sudden change in the voltage curve, and may be caused by a
major generator load change. In this case, the measuring circuit detects a change in the
cycle duration once. This change in the cycle duration is compared with a calculated mean
value from previous measurements. Monitoring encompasses all three phases. The threshold
value in degrees specifies the difference in time between the mean and the current value in
reference to a full cycle. Monitoring can be set in various manners. The phase/vector shift
watchdog may be used as an additional facility for decoupling from the mains.

Monitoring Phase/vector shift monitoring one-/threephase..threephase

------------------------------
one-/threephase .....During single-phase voltage phase/vector shift monitoring, tripping
occurs if the phase/vector shift exceeds the specified threshold value
in at least one of the three phases. Note: If a phase/vector shift oc-
curs in one or two phases, the single-phase threshold value is taken
into consideration; if a phase/vector shift occurs in all three phases,
the three-phase threshold value is taken into consideration. His type
of monitoring is very sensitive, and may lead to false tripping if the
selected phase angle settings are too small.
threephase ............During three-phase voltage phase/vector shift monitoring, tripping
occurs only if the phase/vector shift exceeds the specified threshold
value in all three phases within 2 cycles.

In order to disable the reverse synchronization of the generator to the mains for a certain
time, the delay time for which the generator is to remain in idle or isolated (parallel) opera-
tion can be configured with this parameter. The following applies in the case of generators
with 1-power circuit breaker, which are to be operated in parallel with the mains: If the
mains fails for the duration of the mains settling time, the engine is stopped. If the mains is
available for at least 5 seconds without any interruption, the engine is started.

Firing speed by Firing speed reached via terminal 62 ON/OFF

Term. 62 ON
OFF .......... The discrete input terminal 62 is used as a normal alarm input.
ON .......... The logic to be set applies to the starting procedure:
If the input is set to operating current (NO), the starter is dis-engaged when a
signal is applied. After the termination of the delayed engine monitoring, the
"operating current" is still programmed, however, internally, the device
switches over to the "closed-circuit current" logic (NO), in order to enable the
generation of an alarm tripping in the event of a voltage loss (including set
time lag). The same principle, inverted, also applies to the closed-circuit cur-
rent (NC) tripping. The discrete input is programmed for closed-circuit current
(NC), to dis-engage the starter in the event of a voltage loss. After the delayed
engine monitoring, the discrete input is internally set to operating current (NO)
and is therefore tripped as soon as voltage is applied. The here adjusted
logic applies for the start operation.

ATTENTION!

The various functions of terminal 6 are active at different signal levels!

Function term.6 Function of terminal 6

Sprinklermode
This screen is used to assign a function to the discrete control input terminal 6. A selection
may be made from among the following functions:
• Sprinkler operation,
• Engine enabling,
• External acknowledgment,
• STOP mode,
• Engine blocked or
• Start without CB.

• Sprinkler By resetting terminal 6 (setting a low level) sprinkler operation is activated in accordance with the
functional description. This is terminated by setting terminal 6 (application of a High signal). Attention:
Negative functional logic! (for the function of the sprinkler operation, please also observe Chap-
ter 2.11 "Sprinkler operation" on page 53.)

• Engine enable Terminal 6 in this case has the same function as the STOP push-button: Resetting terminal 6 (applica-
tion of a LOW signal) prevents the engine's starting, and stops the engine if this is already running; the
application of a HIGH signal enables the starting of the engine; the application of a high signal en-
ables the engine for startup. Caution: Via this function, emergency power operation is also prevented
or aborted. Emergency power is not possible without this enable signal! The engine enable function is
only possible in "AUTOMATIC" operating mode.

• Ext. acknowledge In "STOP" and "AUTOMATIC" modes alarms can be acknowledged externally by setting terminal 6
(Change of slope from a LOW to a HIGH signal). In order to achieve further acknowledgement, ter-
minal 6 must accordingly first be reset and then set again. If a continuous HIGH signal is present at
terminal 6, this has no effect on the acknowledgement and suppression of alarm messages.

• ΣΤΟΠ mode By setting terminal 6 (application of a HIGH signal) the STOP mode is chosen. If you remove this
signal the mode will change into the mode which was activated before terminal 6 was set.

• Engine stop By setting terminal 6 (application of a HIGH signal) a start of the engine can be prevented. If the
engine is running because emergency current is present, it is stopped by setting this discrete input. The
discrete input is not inverted. The engine block function is only possible in "AUTOMATIC" operating
mode.

• No CB by start If the terminal 6 is set, the engine starts; no synchronization is carried out and the generator power
circuit breaker is not engaged (no switching to black busbar). The GCB is then inserted only if emer-
gency current is present. After return of the mains, there is a switchover to the mains according to the
set CB logic. The start of terminal 6 is of a higher value than the start via terminals 3/5. If terminal 6
was selected, terminals 3/5 are ignored. If the genset is in mains parallel mode with power circuit
breaker logic "Parallel" and if terminal 6 is activated, the GCB is opened after a reduction in power.
The genset continues to operate without load with the GCB open.

This parameter can only be configured using FL-SOFT3.

PCR3 on bus PCR3 on bus YES/NO

NO
YES ..........The functions of the PCR3 are active. And there is a monitoring whether the
PCR3 is on engine bus. If this parameter is set to YES but the PCR3is not con-
nected to the CAN bus the PCx releases an interface fault.
NO ..........The functions of the PCR3 are blocked and there is no communication monitor-
ing to the PCR3.

Notes to the PCR3 interface faults – The "Interface fault Y1Y5" of the alarm class 1 will be released when the PCx receives no
messages from hte PCR3 for about 5 s. The measuring values of PCR3 are overwritten with "0". Furthermore the relais drops-out (or
picks up according to the configuration). When the PCx receives again data from the PCR3, the relay picks up and the measuring
values from the PCR3 were displayed again. (If an interface fault Y1Y5 will be released for example by a faulty EM1-D communica-
tion, the data of the PCR3 will be furthermore displayed correct.)

Notes to J1939 protocol – In the above table (J1939 'Standard') the messages are listed which can be displayed of the PCx. If a
value cannot be send from the used ECU, a FFxx'h is sent according to the SAE J1939 standard. The PCx identifies this and the
according value will not be displayed. According to the SAE J1939 standard a priority is defined in the CAN-ID of a SAE J1939
message. This will not be regarded from the PCx. The PCx receives messages of all priorities.

Notes to "Interface fault engine bus" – Basically the "Interface fault Y1Y5" is released in alarm class 1 and is shown in the display if
the PCx does not receive CAN data of an active subunit for a certain time. As perhaps several devices are connected to the bus the
relay manager can be configured additionally for every subunit which signals the missing/existing connection to the subunit.

154 HB_PCL1/PCM1-M/PCM1-G_09.04_GB
 NOTE

Please refer to the manufacturer's manual for information about the functionality of the MDEC.

ECU interface monitoring YES/NO

YES .......... If the connection MDEC – PCM or J1939-PCM is interrupted for a certain
time, the message “interf,err. Y1Y5” is displayed with alarm class 1.
NO .......... If the connection MDEC-PCM or J1939-PCM is interrupted, this message is
not displayed. (This setting makes sense, if an engine shutdown is only possi-
ble by disconnecting the power supply of the engine control. Otherwise, an
interface error would be triggered with shutdown).

NOTE

This setting has no effect on the interface error triggering for EM1-D and PCR3. It has also no influence on the
relays with the parameters 134 to 138.

-----------------------------
OFF .......... The coupling to the mtu MDEC is disabled and no MDEC data is processed.
Note The MDEC cannot trigger an interface error Y1Y5.
MDEC and J1939 cannot be operated
Visual/Control - The coupling to the mtu MDEC is enabled, MDEC values and the follow-
simultaneous!
ing parameters are displayed, and values are sent to the MDEC. The MDEC
can trigger an interface error Y1Y5.
Visualization - The coupling to the mtu MDEC is enabled and MDEC values and the fol-
lowing parameters are displayed. The MDEC can trigger an interface error
Y1Y5.
Control...... The coupling to the mtu MDEC is enabled, the following parameters are dis-
played, and values are sent to the MDEC. The MDEC can trigger an interface
error Y1Y5.

(The display values are overwritten with question marks in case of an interface error, trig-
gered by the CCM.)

Note
The MDEC cannot be used together with J1939.

MDEC protocol MDEC protocol V302/V303/V304

Firmware software version of the MDEC.

max.speed loop MDEC speed loop 0..999 rpm

000 rpm
The setting of this mask will be attended, if the setpoint value to the MDEC controller oc-
curs via the CAN bus. For a power control the rated real power will be regulated by the
nominal speed value. The entered speed loop depends on the droop characteristics of the
engine. As an adjustment help, you can determine the speed loop as follows:

Without setpoint value at the MDEC speed governor the engine will be loaded half or full.
The occurred speed break-in can be entered on full load directly as speed loop. If you
measure under half load you have to enter the double value. For more information please
not the manual of the MDEC:

A speed control is only possible if the frequency controller is set to ANALOG. If the control
is not active yet, the set rated speed is calculated as follows:

nAusgabe = nNenn +
((GS − 50% )x nmax Hub )x 2
100%

nAusgabe output value [min-1]

nNenn rated speed [min-1]
GS initial setting [%]
nmaxHub maximum speed loop [min-1] (this parameter)

Note to the MDEC interface error – The "interface error Y1Y5" with alarm class 1 is triggered, if the PCx does not receive an "Alive"
message for about 0,5 s from the MDEC. The measurement values of the MDEC are overwritten with question marks and the MDEC
alarm messages are suppressed. Moreover, the relay with the parameter 137 de-energizes (or energizes depending on program-
ming). If the PCx receives the "Alive" message again, the relay energizes again and the measurement values as well as the alarm
messages of the MDEC are displayed again. (If an interface error Y1Y5 is triggered, which was caused by e.g. a faulty EM1-D
communication, the data of the MDEC is still displayed correctly.)

5 Commissioning

DANGER !!!WI

When commissioning the item, please observe the five safety rules that apply to the handling of live
equipment. Make sure that you know how to provide first aid in current-related accidents and that you
know where the first aid kit and the nearest telephone are. Never touch any live components of the system
or on the back of the system:

LIFE THREATENING

WARNING !

The item may only be commissioned by a qualified technician. The "EMERGENCY OFF function must
function safely before the commissioning and must not depend on the particular engine.

CAUTION !

1. Prior to commissioning, check that all measuring voltages are correctly connected with regard
to phases. The connect commands for the power circuit breakers must be disconnected at
the power circuit breakers. The rotating field must be measured. Any lack or incorrect
connection of measuring voltages or other signals may lead to incorrect functions and
damage the item as well as engines and components connected to the item.

Procedure 2. After checking to ensure that all measuring voltages have been connected to the correct phases,
the supply voltage (12/24 Vdc) has to be connected.

3. By simultaneously pressing the two push-buttons " U SELECT" and "PARAMETER", the configuration
and test mode is accessed. After entering the code number, all parameters are first set (see the
chapter regarding the parameters).

4. Following the application of the supply voltage, please check that all measuring values (voltages,
currents, wattages, power circuit breakers replies) are correctly displayed. The engine must only
be started if the power circuit breaker replies are correct.

5. First start the engine via the "MANUAL" operating mode (press the "MANUAL" push-button)
("START") and then stop it ("STOP"). All generator measuring values must be checked. Please also
check any messages caused by alarms.

6. Check the automatic start procedure via the "TEST" operating mode (press the "TEST" push-
button). Test protection caused by alarms with shutdown.

7. Operating mode "AUTO" (press the push-button "AUTOMATIC"): Automatic starting with subse-
quent synchronization can now be carried out by applying the automatic control inputs and the
engine request.
Check synchronization: Check the generator and the generator busbar rotating field. Check the
connect command with a zero voltmeter (determination of the phase angle) at the generator
power circuit breaker. If several correct synchronizing pulses have been output, switch the oper-
ating mode to "STOP" and reconnect the connect pulse "Command: close GCB" with the engine
at a standstill.

158 HB_PCL1/PCM1-M/PCM1-G_09.04_GB
 8. If Points 1 to 7 have been carried out successfully, you may now initially commence operation in
parallel with the mains with a constant power (approx. 25 % of the generator rated power).
Whilst this is being carried out, the displayed measuring values must be checked. Check GCB
shutdown. Check the real power controller and, if necessary, the power factor ϕ controller. Pre-
specify various setpoint values and check control.

9. If operation in parallel with the mains is carried out in a satisfactory manner, the synchronization
of the mains power circuit breaker must be checked:

At this point, at the latest, it must be ensured that a power failure in the system has been clarified
or registered. During operation in parallel with the mains, the item must be switched to "MAN-
UAL" operating mode; the mains power circuit breaker is then de-activated ("MCB ON" LED is
extinguished). The item must then be switched back to "AUTOMATIC" operating mode.

Check the generator busbar and the mains rotating field. Check the connect command with a
zero voltmeter (determination of the phase angle) at the mains power circuit breaker. If several
correct synchronizing pulses have been output, switch the operating mode to "STOP" and re-
connect the connect pulse "Command: close MCB" with the engine at a standstill.

10.Test emergency power operation functions.

NOTE

The function in automatic mode is influenced via the available input signals "Automatic 1" and
"Automatic 2". Make sure that the reply messages of the power circuit breakers are processed inverted,
i. e., when the power circuit breaker is closed there must be a "reply message applied on the inputs: CB is
open" 0 V (auxiliary contact of the power circuit breaker as a break contact (NC)! - note the description of
the auxiliary and control inputs at the beginning of this manual). It is vital that these replies be connected!

Electrical isolation between voltage supply and discrete control and feedback inputs
Via corresponding external wiring, the common reference point of the discrete inputs can be
electrically isolated from the supply voltage (0 V, terminal 2). This is necessary, for example, if
the discrete inputs are not to be triggered with 24 Vdc and an electrically isolation of the control
voltage (e. g. 220 Vdc, 220 Vac) from the supply voltage must be insured.

6.3.2 Transmission telegram

The data of the following table can be handled by a Gateway or a PLC and can be trans-
ferred to other busses. An PCx is sending the data via circular CAN messages.

The transmitting rate of this communication is 125 kBaud.

The CAN ID, on which the PCx is sending is calculated as follows:

CAN-ID = d‘800 + Item number (or H‘320 + item number)

(The item number is a parameter adjustable on the PCx which influences directly the CAN
ID on which the item sends the visualization message).

A visualization message which is send out of an PCx has got 8 Byte and is built as follows:

Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7

data word 1 data word 1 data word 2 data word 2 data word 3 data word 3
H‘DD MUX number
High-Byte Low Byte High-Byte Low Byte High-Byte Low Byte

In a visualization message the byte 0 is always used to show the hexadecimal value DD.
This one defines the message as a visualization message. As the complete transmission
telegram of the PCx includes more than three words byte 1 sends additionally a MUX
number starting with 0. Therefore it is theoretically possible to send (256 × 3 = 768)
words via the CAN ID. The whole telegram is built up as follows:

line 1: MUX number 0, word 1

line 2: MUX number 0, word 2
line 3: MUX number 0, word 3
line 4: MUX number 1, word 1
line 5: MUX number 1, word 2
line 6: MUX number 1, word 3
.
.
line (n): MUX number (n-1/3), word 1
line (n+1): MUX number (n-1/2), word 2
line (n+2): MUX number (n-1/1), word 3

n depends on the total length of the item special telegram and can not be larger than H’FF.

NOTE

The following data is transferred in the 'extended blocks' of the PCx. The data volume, which is added by
the ' extended blocks ', results that a Gateway PCK4 can only transfer the data of the first four PCx
anymore. If it is necessary that all data of all PCx is transferred, a second Gateway PCK4 has to be
used.

The CAN protocol for remote control of the PCx is available on request. We however
recommend to use a Gateway. The following three data words can be received by the
PCx. Please see in the manual of the GW 4 how you can control several PCx.

6.3.4 Notes (on interface)

a.) Coding of the current direction

The current direction can be recognized via the code word prefix. A positive transmitted
value indicates supply (power output), a negative transmitted value indicates power con-
sumption (incoming supply).

b.) Coding of the power default

The following power values may be pre-specified: fixed power (F power), outgoing/export
power (E power) and incoming/import power (I power). The real power setpoint is trans-
mitted in binary form using bits 0..13. The control argument must be transmitted in the basis
of bits 14 and 15. In this case, the following coding applies:

Control argument Bit 15 Bit 14

F power 0 1
E power 0 0
I power 1 1

Examples:
F power of 150 kW is to be compensated. The value transmitted is then:
01/00 0000 1001 0110 B # 4096 H

L power of 300 kW is to be compensated. The value transmitted is then:

00/00 0001 0010 1100 B # 012C H

I power of 600 kW is to be compensated. Negative power is transmitted. The value

transmitted is then:
11/11 1101 1010 1000 B # FDA8 H
