FRONT KEYBOARD
OFF, MAN, AUT and TEST keys - To choose function mode.
START and STOP keys - Only enabled and used to start and stop genset in MAN mode. Pressing the START key will attempt to start the machine in
semiautomatic mode, while holding it down will maintain the start command in manual mode. The LED flashing on the engine symbol indicates the engine is
running with the alarms inhibited, and fixed access at the end of the inhibit alarms time. The engine can be stopped immediately with the OFF key.
MAINS and GEN keys - Only enabled in MAN mode and used to switch the load from the mains to the generator and vice versa. The green LEDs lit near the
mains and generator symbols indicate the respective voltages available within the preset limits. The LEDs lit near the switching symbols indicate the circuit G
breakers have been closed. They will flash if the circuit breakers closing or opening feedback signal does not correspond to the state of the command.
Key  - Calls up the main menu and is also used to confirm choices.
B
I335 GB I D F E 02 14

Keys  and  - Used to scroll the pages of the display or select the list of options in a menu.


Key - Used to select the Mains or Generator measurements, or to decrease a number.


Key - Used to scroll sub-pages or increase a number.

FRONT LEDs
OFF, MAN, AUT and TEST LED (red) - Lit LED indicates active mode. If the LED flashes, remote control via serial interface is enabled (and therefore the
operating mode could be changed by a remote command).
Engine running LED (green) - Indicates the engine is running. The RGK700 detects the state of the engine running on the basis of several signals (generator
voltage/frequency, D+, AC, W, Pick-up, etc.). The LED lights when any one of these signals is present. The LED flashes when the engine is running, but the
protections (Alarms) associated with this state have not been enabled, which is usually the case for a few seconds after starting.
Mains/generator voltage present LEDs (green) - When lit, theses indicate that all the parameters of the respective power sources are within the limits. Any
anomaly will immediately turn the LEDs off. The state of the LEDs instantaneously follows the voltage/frequency trend, without programmed delays.
Mains/generator load LEDs (yellow) - Indicate the load is connected to the respective power sources. These light when feedback signals are received if
programmed, otherwise they light for output commands. If they are blinking, this indicates that the actual state of the circuit breaker (read through the feedback
inputs) does not correspond to the state of the RGK700 command.
Alarm LED (red) - Flashing, indicates an active alarm.

OPERATING MODES
OFF mode - The engine will not start. The engine will stop immediately when this mode is selected. The mains contactor is closed. This mode reproduces the
state of the RGK700 when it is not powered. Use this system mode to program the parameters and open the commands menu. The siren is disabled in OFF
mode.
MAN Mode - The engine can only be started and stopped manually using the START and STOP keys, as is the case for switching the load from the mains to the
generator by pressing the MAINS/GEN keys and vice versa. Holding down the START key extends the set starting time. When START is pressed once, the
generator will attempt to start in semiautomatic mode on the basis of the times set.
AUT Mode - The engine of the RGK700 is started automatically in the case of a mains outage (outside the set limits) and stops when the mains parameters are
once again within said limits, on the basis of the times set in menu M13 Mains control. In the presence of voltage, the load is switched automatically in both
directions.
The RGK700SA is started and stopped remotely through a digital input (remote starting) normally controlled by an ATS. The load can be switched automatically
or controlled remotely.
For both models, if the engine fails to start, the system continues attempting to start the engine up to the maximum number of programmed attempts. If the
automatic test is enabled, it runs at the preset times.
TEST Mode – The engine is started immediately even in the absence of the conditions normally required for the automatic mode. The engine starts in the
programmed automatic mode. There is normally no load switching. If there is a mains outage while the RGK700 is in TEST mode, the load is switched to the
generator. If mains voltage is restored, the load with remain switched to the generator until the operating mode is changed.

– Some measurements may not be shown depending on the system programming and connections (for example if a fuel sensor is not set, the relevant page
will not be shown).


– On some pages of the RGK700, the display can be switched from the mains measurements to the generator measurements and vice versa with key . The
source displayed is always indicated, either in the middle of the page or by the icons M and G in the status bar.


– Sub-pages, which can be opened with key , are also available on some pages (displaying voltages and currents in the form of bar graphs, for example).
– The user can specify which page and which sub-page the display should return to automatically when no keys have been pressed for a certain time.
– The system can also be programmed so the display remains were it was last.
– You can set this function in menu M01 – Utility.

HARMONIC ANALYSIS PAGE

– In the RGK700 it is possible to enable the calculation of the FFT harmonic analysis up to the 31st order of the following measurements:
• phase-to-phase voltages
• phase-to-neutral voltages
• currents
– To enable the harmonic analysis, set parametr P23.14.
– For each of these measurements, there is a display page that graphically represents the harmonic content (spectrum) through a bar graph.
– Every column is related to one harmonic order, even and odd. The first column shows the total harmonic distortion (THD).
– Every histogram bar is then divided into three parts, one each phase L1,L2, L3.
– The value of the harmonic content is expressed as a percentage with respect to the fundamental (system frequency).



– It is possible to show the harmonic content in numeric format, selecting the required order through and . The lower part of the screen will display a
little arrow that points to the selected column, and the relative percentage value of the three phases.
– The vertical scale of the graph is automatically selected among four full-scale values, depending on the column with the highest value.

WAVEFORM PAGE
– This page graphically views the waveform of the voltage and current signals read by the RGK700.



– It is possible to see one phase at a time, selecting it with and key.

– The vertical scale (amplitude) is automatically scaled in order to fit the waveform on the screen in the best possible way.
– The horizontal axis (time) shows two consecutive periods referred to the fundamental frequency.
– The graph is automatically updated about every 1s.

USER PAGES
– The user can create a maximum of 4 customised display pages.
– Each of these pages can view 3 measurements, freely chosen among the available readings of the RGK700.
– The title of the page can be freely programmed by the user.
– The user pages are placed in a position that allows to reach them easily starting from the first page, by pressing button .

INPUTS, OUTPUTS, INTERNAL VARIABLES, COUNTERS, ANALOG INPUTS

– The inputs and outputs are identified by a code and a sequence number. For instance, the digital inputs are identified by code INPx, where x is the number of
the input. In the same way, digital outputs are identified by code OUTx.

OUTx Digital Outputs 1…7 ––

COMx Communication ports 1 –– B
I335 GB I D F E 02 14

RALx Remote relays for Alarm / status –– 1…24

– In a similar way, there are some internal bit-variables (markers) that can be associated to the outputs or combined between them. For instance, it is possible
to apply some limit thresholds to the measurements done by the system (voltage, current, power, etc.). In this case, an internal variable named LIMx will be
activated when the measurements will go outside the limits defined by the user through the dedicated setting menu.
– Furthermore, there are up to 4 counters (CNT1..CNT4) that can count pulses coming from an external source (through a digital input INPx) or the number of
times that a certain condition as been verified. For instance, defining a limit threshold LIMx as the count source, it will be possible to count how many times
one measurement has exceeded a certain limit.
– The following table groups all the I/O and the internal variables managed by the RGK700.

LIMIT THRESHOLDS (LIMX)

– The LIMn thresholds are internal variables whose status depends on the out-of-limits of one particular measurement set by the user (e.g. total active power
higher than 25kW) among all those measured.
– To make the setting of the thresholds easier, since the limits can span in a very wide range, each of them can be set using a base number and a multiplier
(for example: 25 x 1k = 25000).
– For each LIM, there are two thresholds (upper and lower). The upper threshold must always be set to a value higher than the lower threshold.
– The meaning of the thresholds depends on the following functions:
Min function: the lower threshold defines the trip point, while the upper threshold is for the resetting. The LIM trips when the selected measurement is less than
the Lower threshold for the programmed delay. When the measured value becomes higher than the upper setpoint, after the set delay, the LIM status is reset.
Max function: the upper threshold defines the trip point, while the lower threshold is for the resetting. The LIM trips when the selected measurement is more
than upper threshold for the programmed delay. When the measured value decreases below the lower setpoint, after the delay, the LIM status is reset.
Max+Min function: both thresholds are for tripping. When the measured value is less than lower or more than upper setpoints, then, after the respective delays,
the LIM will trip. When the measured value returns within the limits, the LIM status will be immediately reset.
– Trip denotes either activation or deactivation of the LIM variable, depending on ‘Normal status’ setting.
– If the LIMn latch is enabled, the reset can be done only manually using the dedicated command in the commands menu.
– See setup menu M24.

REMOTE-CONTROLLED VARIABLES (REMX)

– RGK700 can manage up to 16 remote-controlled variables (REM1…REM16).
– Those are variables which status can be modified by the user through the communication protocol and that can be used in combination with outputs,
Boolean logic, etc.
– Example: using a remote variable (REMx) as a source for an output (OUTx), it will be possible to freely energise or de-energise one relay through the
supervision software. This allows to use the RGK700 relays to drive lighting or similar loads.
– Another possible use of REM variables is to enable/disable other functions remotely, inserting them into a Boolean logic in AND with inputs or outputs.

USER ALARMS (UAX)

– The user has the possibility to define a maximum of 8 programmable alarms (UA1…UA8).
– For each alarm, it is possible to define:
• the source that is the condition that generates the alarm,
• the text of the message that must appear on the screen when this condition is met.
• The properties of the alarm (just like for standard alarms), that is in which way that alarms interacts with the generator control.
– The condition that generates the alarm can be, for instance, the overcoming of a threshold. In this case, the source will be one of the limit thresholds LIMx.
– If instead, the alarm must be displayed depending on the status of an external digital input, then the source will be an INPx.
– With the same criteria, it is possible to also link complex conditions to an alarm, resulting from the logic combination of inputs, limits, etc. In this case, the
Boolean logic variables PLCx must be used.
– For every alarm, the user can define a free message that will appear on the alarm page.
– The properties of the user alarms can be defined in the same way as the normal alarms. You can choose whether a certain alarm will stop the engine, activate
the siren, close the global alarm output, etc. See chapter Alarm properties.
– When several alarms are active at the same time, they are displayed sequentially, and their total number is shown on the status bar.
– To reset one alarm that has been programmed with latch, use the dedicated command in the commands menu.
– For details on alarm programming and definition, refer to setup menu M32.

PLC LOGIC (PLCX)

– You can set a ladder program with the Customisation manager software for the RGK PLC logic, to easily create any function required for the genset
accessory applications.
– You can enter all the variables managed by the RGK700 in the program logic, such as inputs (INPx), limit thresholds (LIMx), remote variables (REMx), and
controller states (RALx), etc.
– The results of processing the various branches of the ladder logic are saved in internal variables (PLCx) which can then be used to control the outputs of the
RGK700, or as backup memories to build a more complex logic, or also to control user-defined alarms (UAx). G
– The logic function created with the ladder program can be verified in real time and if necessary corrected in the relevant window of the Customisation
manager.

I335 GB I D F E 02 14

AUTOMATIC TEST
– The automatic test is a periodic test carried out at set intervals (set during setup) if the system is in AUT mode and the function has been enabled.
– It is possible to decide in which days of the week the automatic test can be executed and at what timeof the dauy (hours:minutes).
– See menu M16 Autoamtic test formore details on automatic test programming.
– After starting, the genset runs for a set time, after which it will stop. The message 'T.AUT' is displayed before the generator starts.
– The automatic test can be set to run in setup also if there is an external stop signal.

– The automatic test can be enabled/disabled without opening the Setup menu in the following way:


• Open the 'AUTOMATIC TEST' page and press the keys and START to enable the function, or the keys and STOP to disable it.
– The automatic test can be stopped with the OFF key.

SLEEP MODE
– The sleep mode allows the RGK to enter a low battery consumption mode, where current sink is reduced to about …mA.
– To enter sleep mode, use command C25 in command menu.
– The back light is turned off and the display shows sleep icon. Led OFF flashes slowly.
– In this mode the RGK act like it is powered off.
– To quit sleep mode and go back to normal operation, press OFF button.

CANBUS
– The CAN port allows RGK700 controllers to be connected to the electronic control units (ECU) of modern engines in order to:
– Read the measurements contained in the ECU without adding sensors to the engine
– Considerably simplify wiring
– Obtain complete, detailed diagnostics
– Avoid assembly of CIU or Coo (coordinator) type decoding boards
– Permit direct control from CAN of engine stopping and starting (where permitted)
– The board functions in combination with the ECUs of the engines most widely used in gensets applications, using the standard defined by the SAE J1939.
– For details on CAN parameters, see setup menu M21 CANBUS.

SUPPORTED MEASUREMENTS
– The CAN port is able to decode and make available a set of measurements defined by the J1939 standard and identified by a number (SPN, Suspect
Parameter Number).
– According to the type of engine, a certain number of measurements are available (a sub-set of possible measurements) that are shown on the display of the
RGK700.



– The measures are grouped in several sub-pages, that can be viewed pressing and keys.

– The next page shows the diagnostic messages.

– Engine speed, oil pressure and cooling fluid temperature are taken directly from the CAN; therefore, neither wiring or setting of the related sensors is
required.

– When the ECU is off, the measurements are not available and are therefore replaced by hyphens.
– If a measurement is not availabe on a particular engine, NA (Not Available) is displayed.
– If a measurement is incorrect (for example, the sensor is disconnected) ERR is displayed instead of this.

DIAGNOSTICS
– In the case of failures, many ECUs highlight the problem with a J1939 standard code, called DTC (Diagnostic Trouble Code) consisting of SPN+FMI, where
SPN (Suspect Parameter Number) identifies the signal affected by the fault, while FMI (Failure Mode Indicator) identifies the type of failure.
For example:
SPN-FMI
100-01
indicates SPN 100 (oil pressure) and FMI 01 (too low).
– In view of the many sensors connected to an ECU, a high number of possible codes is managed. In the case of a fault, this is indicated on the display of the
RGK700 with both a code and with a description in the related language, in the last of the sub-pages dedicated to the CAN.
– In the case of several simultaneus alarms, these are cycled periodically.
– According to the seriousness of the code, an amber alarm indicator (warning) or red alarm indicator (critical alarm) is usually generated.
– Some ECUs do not use the J1939 standard to code the alarms. Also in this case, the DTCs are displayed with their numeric code and, when possible, with an
uncoded description.
– To reset the alarms, press  or OFF, as usual.
– If enabled, the RGK700 will send a reset alarm command, according to the type of ECU selected, on the BUS.

IR PROGRAMMING PORT
– The parameters of the RGK700 can be configured through the front optical port, using the IR-USB CX01 programming dongle, or with the IR-WiFi CX02
dongle.
– This programming port has the following advantages:
• You can configure and service the RGK700 without access to the rear of the device or having to open the electrical board.
• It is galvanically isolated from the internal circuits of the RGK700, guaranteeing the greatest safety for the operator.
• High speed data transfer. G
• Ip65 front panel.
• Limits the possibility of unauthorized access with device config.

I335 GB I D F E 02 14

– Simply hold the CX.. dongle up to the front panel, connecting the plugs to the relevant connectors, and the device will be acknowledged as shown by the
LINK LED on the programming dongle flashing green.

PARAMETER SETTING (SETUP) WITH PC

– You can use the Customization manager set-up software to transfer (previously programmed) set-up parameters from the RGK700 to the hard drive of the
PC and vice versa.
– The parameter may be partially transferred from the PC to the RGK, transferring only the parameters of the specified menus.
– The PC can be used to set parameters and also the following:
• Data on the characteristics of the pressure, temperature, fuel level sensor curves, and the generator protection
• Customised logo displayed on power-up and every time you exit keyboard setup.

P22.01…P22.05 – Used to start the generator when the load exceeds a threshold in kW measured on a branch of the mains, normally to prevent exceeding the
maximum limit set by the energy provider supplying the load with the generator. When the load drops to below P22.04, the generator is stopped and
the load is switched back to the mains.
P22.06 – Enable dummy load management, setting the number of steps for the same. When the generator load is too low, dummy loads are switched in for the
maximum number of steps set on the basis of incremental logic.
P22.07…P22.10 – Thresholds and delays for switching-in or switching-out a dummy load step.
P22.11…P22.12 – If enabled, the dummy load will be switched in and out cyclically at the time intervals defined by these parameters.
P22.13 – Enable non-priority load switch in and out (load shedding) defining the number of load sections to disconnect. When the load on the generator is low
enough, non priority loads are switched in. Otherwise when it is too high, non-priority loads are disconnected in various sections, on the basis of
incremental logic.

P23.01 – Number of rent hours to pre-charge in the counter on command C14 Recharge rent hours.
P23.02 – Rent hours counter down count mode. When this counter reaches zero, the A48 Rent hours expired alarm is generated. Total hours = Decreasing
count on the basis of the real time expired. Engine hours = The operating hours of the engine. Load hours = Hours supplying load.
P23.03 – Enable emergency input incorporated in terminal +COM1, common positive of outputs OUT1 and OUT2 (default function: Start and fuel solenoid
valve). ON = When +COM1 is disconnected from the positive terminal of the battery, the A23 Emergency stop alarm is automatically generated.
OFF = When +COM1 is disconnected from battery terminal, no alarm is generated.
P23.04 – Enables Mutual stand-by function and defines the communication port used to connect to an alternative generator.
P23.05 – Alternating genset mode for mutual stand-by function. Start = The gensets alternate with every request for intervention. If necessary the genset with
the lowest number of operating hours is started, and remains operational as long as required (until the conditions that started the genset are no longer
applicable). Time = If necessary the genset with the lowest number of operating hours is started, and remains operational until its operating hours
exceed those of the alternative genset by an amount equal to or greater than those programmed with the following parameter. When this condition
arises, the load is switched from one genset to the other.
P23.06 – Max. deviation on the operating hours of the gensets in mutual stand-by. See previous parameter.
P23.07 – Type of connection between RGK700 and RGKRR relay remote unit. OFF = Communication disabled. OUT= Communication through programmable
output set for Remote alarms function, connected to the digital input of the RGKRR. CAN = The RGK700 and RGKRR communicate through the CAN
interface. Unless there are indications to the contrary for a specific ECU, it is usually possible to communicate simultaneously with the RGKRR and the
engine ECU on the same CAN line. See RGKRR manual for more details.
P23.08 – Normal = Standard operation in AUT mode. EJP = 2 programmable inputs are used, set with the functions Remote starting and Remote switching for
EJP. When the starting input closes the engine start (P23.09) delay is enabled, after which the start cycle runs. Then, when the remote switching go-
ahead is received, if the engine started properly, the load will be switched from the mains to the generator. The load is restored to the mains by the
remote switching go-ahead opening and the genset runs a stop cycle when the start input opens. The EJP function is only enabled if the system is in
automatic mode. The cutouts and alarms function as usual. EJP-T = The EJP/T function is a simplified variation of the previous EJP, and in this case
the engine start is controlled in the same way, but a timer switches the load instead of an external signal. This function therefore uses only one digital
input, the starting input. The switching delay starts from when the start command closes, and can be set using parameter P23.10 Switching delay.
SCR = The SCR function is very similar to the EJP function. In this mode, the starting input enables genset starting as for EJP, without waiting for
delay P23.09. The remote switching input still has a switching go-ahead function after Switching delay P23.10.
P23.09 – Delay between the closing of the generator EJP starting signal and the beginning of the starting cycle.
P23.10 – Delay for switching the load from mains to generator in EJP and SCR mode.
P23.11 – If ON, in EJP and EJP-T mode, the load will not be switched back to the mains in the case of a generator malfunction, but only when the signals on the
EJP inputs give a go-ahead.
P23.12 – If On, in the case of a mains switchgear malfunction which does not prevent closing and the consequent generation of the alarm A41 Mains contactor
anomaly, the engine is started and the load switched to the generator.
P23.13 – Defines in which operating mode the programmed output with the Operating mode function is enabled. For example, if this parameter is programmed
for O+M, the Operating mode output will be enabled when the RGK700 is in OFF or MAN mode.
P23.14 – Defines whether the harmonic analysis should be performed on the generator voltage and current waveforms. OFF = Harmonic analysis not
performed. THD = THD (Total Harmonic Distortion) display and calculation only. THD+HAR = THD display and calculation of the harmonic spectrum
and wave form.
