Description of the controller system (with all options)
NT Family controllers are comprehensive AMF-controllers for single and multiple generating sets operating
in stand-by or parallel modes. A modular construction allows upgrades to different levels of complexity in
order to provide the best solution for various customer applications.
NT Family controllers are equipped with a powerful graphic display showing icons, symbols and bar-graphs
for intuitive operation, which sets, together with high functionality, new standards in Gen-set controls.
The controller automatically starts the gen-set, closes the Gen-set C.B. when all conditions are met, then
stops the engine* (* sw GeCon opens GCB only, not stops the engine) on external signal or by pressing
push buttons.
Parallel to the Mains operation is a standard feature. Isolated parallel and Power Management System
support are optional. Forward and reverse synchronizing, Generator protections, Mains protection including
vector shift, load and power factor control are the major functions provided. Interfacing to foreign
synchronizers and load sharers is supported.
The key feature of the controller is its easy-to-use operation and installation. Predefined configurations for
typical applications are available as well as user-defined configurations for special applications.
Comparing of IGS-NT-GeCon-MARINE 3.2 with standard gen-set fw
GeCon does not take care of Engine control
GeCon accepts in SEM mode external control of GCB and Engine
GeCon can control the engine via Binary start/stop output signals only – see below. The independent Engine
controller (e.g. ID-DCU) is expected.
Synchronizing and unloading timeouts can be disabled by setpoint setting (or Force value function)
All regulations (load, VAr sharing, frequency, voltage) can be disabled by setpoint change or by Force value.
Interface GeCon to engine controller is provided by I/O wires no by communication line.

BI: ReadyToLoad – signal from Engine unit – it means that Engine is ready (speed is ok, no 2nd level
alarms) and can be loaded.
Other signals:
- Information about Warnings / SD in one unit can be sent to second unit.
- ECU – in case of Ecu communicating via CAN bus J1939 – GeCon can be connected to CAN1 for
showing ECU values on the display
- Interconnection on CAN2:
o For Time and Date synchronisation only- in case of IGS-NT and ID-DCU
o In case of connection IB-NT or I-LB+ - you can monitor both kind of units (IGS-NT, ID-DCU)
o In case of connection display – you can switch between both kind of units (IGS-NT, ID-DCU)

Controller modes
OFF mode
Use OFF mode to block controller functions (even if is power on). OFF mode is used for controller firmware
or configuration change.
Binary outputs (e.g. GCB CLOSE/OPEN) are not energized, all closed Binary outputs are opened when
controller is switched to OFF mode.
Gen-set cannot be started and operated from IGS-NT-GeCon controller – no response for panel buttons and
Binary input commands.
Hint:
Switching to OFF mode is blocked on running engine to avoid accidental engine stop by mode change or by
firmware or configuration programming.

SEM mode
Engine start can be activated from
o Engine controller (e.g. ID-DCU, ID-MCU)
o GeCon panel – Start button
o GeCon BI: StartButton
o Remotely e.g. from InteliMonitor
GeCon BI: ReadyToLoad initiates GeCon “Running” state” - activates Gener protect: Min stab time a Max
stab time within the generator electric protections are activated.
Gen-set is loaded/unloaded from
o GeCon panel – GCB button
o GeCon BI: GCBButton
o Direct GCB “hand” control
o Remotely e.g. from InteliMonitor
o LBI: Gen unload
GCB closing from controller can be blocked by BI: GCB disable (does not block synchronization process)

Automatic mode is influenced by ProcessControl: Island enable, ParallelEnable, Synchro enable setpoints.
Following procedure corresponds to setting No.1 from table above.
1) After the input Rem start/stop is energized, controller starts the gen-set. If MCB feedack is active, the
controller will synchronize the gen-set to mains and ramp up the load, depending on the ProcessControl
set points adjustment.
2) If a mains failure is recognized, the controller will open the GCB to separate the failed mains from the
generator. After the mains breaker has been open (MCB feedback is de-energized), the controller will
close the GCB again to the island (stand-by) operation.
3) If mains recovers again, the GCB is open again to allow the MCB to be closed (manually or in general
not with a command from the controller). After both mains is present and MCB closed, the controller will
synchronize again with the healthy mains and close the GCB.
4) If input Rem start/stop is de-energized, controller will softly unload the gen-set back to the mains, then
open the GCB, cool down and stop the gen-set.
TEST mode
Use TEST mode for Gen-set start test if the Mains is OK or to transfer the load to the gen-set when Mains
fail is announced in advance.
HINT
The controller does not respond to GCB ON/OFF , STOP, START in Return To mains = ENABLED.
Gen-set automatically starts, when TEST mode is selected.

Mains parameters out of limits during synchronising
In case that mains parameters get out of permitted limits during synchronizing to mains (reverse or forward),
the regulation of gen-set speed and voltage according to mains frequency and voltage is interrupted. During
the state, when parameters reach out of limits, until “Mains fail” is issued, the engine speed and voltage
regulation output is kept on the last value.

Load shedding
Load shedding function is dedicated for tripping of non-essential load in case of high generator current, or
drop of generator frequency above/below preadjusted limits, for preadjusted time.
All LOAD SHED outputs are activated (closed) to trip the unessential load when gen-set goes to island:
a) When GCB is closed after mains fail and gen-set starts in AUT mode.
b) When MCB opens from parallel to mains operation in AUT mode.
c) Before MCB is opened in SEM mode by button.
The load shedding function is active in all controller modes except OFF and MAN.
Load shedding has ten steps and each step is linked with its own Load shed x binary output. The non
essential load shedding is based on generator current and generator frequency. There is only one level for
current load shedding and one level for frequency load shedding for all 10 steps, as well for reconnection
level and delay. Load shed can only move from one step to the next, e.g. No LoadShed to LdShed S1 to
LdShed S2 to LdShed S10 and vice versa.
If manual reconnection of the load is desired, the AutoLd recon setpoint needs to be disabled (AutoLd recon
= DISABLED) and the MAN load recon binary input needs to be configured.
Rising edge on this input resets the controller to a lower stage, but only if the load is under the Ld recon level
at that moment.
The current load shedding can be activated in case any of phase current exceeds the adjusted limit. The
reconnection is able only in case all of the current values are below reconnection level.

phases, each phase can activate the load shedding. On the picture, due to transparency, only 3 load shed
outputs are depicted, not all 10.
The generator frequency based load shedding is in fact the same, but fall below preadjusted limit is watched,
instead of exceeding of the limit as in case of current load shedding.

Affects the behavior in TEST mode. Before the activation of this function
1. adjust setpoint AMF settings: ReturnTo mains = DISABLED
2. adjust Process control: MFStart enable = YES.
3. switch controller to Test on load mode (see drawing below)
Gen-set starts and goes to load (synchronizes to the mains, closes GCB and opens MCB) automatically
when this input is closed even if Mains is OK.
Transmition of power from mains to generator
Behaviour of function depends on settings of setpoint ProcessControl:I/E-Pm meas. If the mains import is
measured (ProcessControl:I/E-Pm meas = IM3 CT INPUT or ANALO INPUT) then there is no time
limitation for unloading and opening of MCB. The MCB is opened when the Import/Export goes below 0 ± 5%
of Basic settings: Nomin power. If the setpoint ProcessControl:I/E-Pm meas = NONE then the MCB is
opened after delay given by setpoint AMF settings: BreakerOverlap.
Transmition of power from generator back to mains
GCB is opened when the power on gen-set is drops under level given by setpoint Sync/Load ctrl: GCB
open level at the least after delay given by setpoint AMF settings: BreakerOverlap.
Test on load with break (interruption)
The transfer of the load in TEST mode can be performed with interruption in case that the parallel to mains
operation is undesirable. Set setpoints ProcessControl:Parallel enable = NO or ProcessControl:Synchro
enable = NONE or REVERSE, ProcessControl:Island enable = YES: If the LBI Test on Load gets active the
load is passed from the mains to the gen-set with interruption. Controller opens MCB and closes GCB after
delay given by AMF settings:FwRet break. After deactivation of LBI Test on Load GCB is opened and and
MCB Is closed after delay given by AMF settings:FwRet break.

Temperature derating function
decreases genset power depend
on setpoints DeratingX strt,
DeratingX end and DeratedX pwr.
Temperature derating starts at
DeratingX strt temperature.
At DeratingX end temperature runs
genset at DeratedX pwr level.
Above DeratingX end temperature
Genset runs at constant DeratedX
pwr.
It is possible to configure both binary inputs (Remote TEST and Test on load) to only one controller physical
binary input internally.
Power derating
This function linearly decreases genset nominal power according to analog input value.
Gen-set power starts decreasing when temperature measured by Analog input PowerDeratingX exceeds
DeratingX strt value.
Gen-set power is at DeratedX pwr value when temperature measured by Analog input Power deratingX is
equal or higher than DeratingX end value.
Hint:
To use Power derating function configure at first Analog input PowerDeratingX to any IGS-NT or IS-AIN
analog input terminal by GenConfig.
When Power derating function is active the generator overload protection is based on the Derated power! ! !
Derated power value Pg derated is visible in the controller measure screen.
When derating function is not active the Derating power is equal to Nominal power.
Example :
Nomin power = 200 kW, Derating1 strt = 70 °C, Derating1 end = 100 °C, Derated1 pwr = 70 %.
Genset is running at Nominal power 200 kW. When temperature reached 70 °C the genset power starts
decreasing. When temperature reached 100 °C genset runs at 70 % of Nominal power = 140 kW. When
temperature increased above DeratingX end temperature level, gen-set power stays at DeratedX pwr level
140 kW.
Protection mode settings
Protections in this application are affected by Setpoint ProtectionMode (group ProcessControl).
This setpoint is active in MAN,SEM and AUT mode.
Setpoint ProtectionMode has 2 options of settings:
ACTIVE:
Standard setting – all protections are active, in case of 2nd level alarm the breaker is opened/controlled.
(2-nd level alarms are evaluated, GCB or MCB is controlled)
NOT ACTIVE:
2-nd level alarms are evaluated only , but GCB or MCB are NOT controlled (no actions).
Exceptions are Emergency Stop and Sd override alarms type.

internally within the controller.
Related binary outputs:
- CB close/open – output for circuit breaker. Equals to 1 during the time when CB is requested o be
closed.
- CB ON coil – output for closing coil of the CB. 2s pulse (5s if synchronising is not provided by the
particuilar CB) is used for closing the CB.
- CB OFF coil – output for opening coil of the CB. 2s pulse (5s if synchronising is not provided by the
particuilar CB) is used for opening the CB.
- CB UV coil – output for undervoltage coil of the CB. Permanently active, 2s negative pulse (5s if
synchronising is not provided by the particuilar CB) is used for CB opening request
- CB status – output indicating CB status as evaluated by the controller. This signal is used for lighting
LEDs on the panel, switching the regulations, CB fail evaluation, etc.

In case that CB fail is detected after switching the controller on (CB is closed), the CB OFF coil output is
activated immediatelly.
NOTE:
If the MCB or GCB feedback gets active during synchronization the breaker is imediately closed.
CAUTION!
In case that MCB feedback is active (MCB is expected as closed) and “MCB fail” is reported due to previous
incorrect manipulation of MCB, in the moment of Fault reset, the MCB fail is cleared and the controller
internally goes to “closed” state. I.e. MCB fdb status is confirmed and the output MCB close/open is
energized.
MCB fail Information
Opening of the MCB externally is allowed because external protection device may open it based on its
protections. The controller will try to reclose the breaker if Mains protect type protection is not configured
accordingly (e.g. external protection device/relay does not allow user to send this type of signal or such
wiring is impractical). After failed attempt to close the breaker, the controller issues standard alarm and in
AUT mode starts the engine and consequently closes GCB breaker.
Warning!
In this case, if the supposed opening of the MCB is caused merely by MCB feedback failure and
the actual position of the MCB is still closed, the controller will close GCB to the Mains voltage
directly without synchronizing because it cannot be distinguished what exactly happened. This
situation can be possibly harmful to the personnel or the equipment. Should this be the case, the
following solution is proposed:

Remote Alarm Messaging
It is possible to use up to five channels for Active Call, Email and SMS upon defined type of Alarm. It is
possible to define protection type for all ENABLED channels to react. All the possibilities in the controller are:
History record, Alarm only, Warning, Mains protect and Mains protect with Reset. Find more information
about alarm types in the chapter Protections and alarm management.
Communication Types for Remote Alarm Messaging
Below there all types of communication available for each Active Call channel.
DATA-ANA: This option sends a complete archive to the recipient's PC via analog modem. An analog
modem must be connected either to one of controller COM ports or to one of I-LB modules connected to the
controller via CAN2 bus. The channel address must contain complete telephone number of the recipient's
PC where InteliMonitor is running in Active call receiving mode.
DATA-GSM: This option sends a complete archive to the recipient's PC via GSM modem. A GSM modem
with activated CSD data transfers must be connected either to one of controller COM ports or to one of I-LB
modules connected to the controller via CAN2 bus. The channel address must contain complete telephone
number of the recipient's PC where InteliMonitor is running in Active call receiving mode.
DATA-ISDN: This option sends a complete archive to the recipient's PC via ISDN modem. An ISDN modem
must be connected either to one of controller COM ports or to one of I-LB modules connected to the
controller via CAN2 bus. The channel address must contain complete telephone number of the recipient's
PC where InteliMonitor is running in Active call receiving mode.
DATA-CDMA: This option sends a complete archive to the recipient's PC via CDMA modem. A CDMA
modem must be connected either to one of controller COM ports or to one of I-LB modules connected to the
controller via CAN2 bus. The local CDMA network must allow point-to-point data transfers. The channel
address must contain complete telephone number of the recipient's PC where InteliMonitor is running in
Active call receiving mode.
SMS-GSM: This option sends a short text message (SMS) containing the actual Alarmlist contents to the
recipient's mobile phone via the GSM modem. The channel address must contain complete telephone
number of the recipient's mobile phone.
SMS-CDMA: This option sends a short text message (SMS) containing the actual Alarmlist contents to the
recipient's mobile phone via the CDMA modem. The channel address must contain complete telephone
number of the recipient's mobile phone.

IB-E-MAIL: This option sends an e-mail containing the actual Alarmlist contents and latest 20 history records
(only date, time, reason) to the recipient's mailbox via the IB-COM module or IG-IB module. The channel
address must contain valid e-mail address of the recipient.
NOTE:
The SMTP settings (SMTP authent,SMTP user name, SMTP password, SMTP address, Contr mailbox) must
be properly adjusted for sending e-mails.
Example of setting
There is an example of setting of Remote Alarm Messaging. In this case active calls we be triggered on
Mains protect and Mains protect with Reset alarms. Message is sent via email to
emailAddress@domain.com (Channel 1 – available for NTC controller or with any controller with connected
IB-NT or I-LB+), archive is sent via ISDN modem to the number +111222333444 (Channel 2) and SMS is
sent to the number +999111333555 (Channel 3).
It is also possible to adjust number of attempts that controller performs in case of not successful Active Call –
Comms settings:ActCallAttempt. The language of messages can be changed –
Comms settings:Acall+SMS lang (use Translator and Languages tabs in GenConfig to adjust languages).
Up to five channels can be used.
Variable speed support
This fw contains variable speed support which is used on Hybrid ship (ship with DC bus).
Variable speed control is usually used on ship where the gen-sets work in long term period on small load. By
changing speed on genset is possible to achieve lower fuel consumption.
Frequency (and Voltage) are usually control according to current load.
For variable speed is used:
Setpoints:
Nominal freq 30..65 Hz (step 1 Hz) FV (Basic settings Group)
ForceBlock6Del 0-60s (step 0,1s) FV (Delays/Timers Group)
GenNomV, BusNomV FV (Basic settings Group)
Voltage dependence on frequency
In generator is induced magnetic flux, which is almost constant in various RPM.

Temporary blocking of fix frequency and voltage protections
Temporary blocking of frequency and voltage fix protections
After submitting a request for change of nominal frequency and voltage the generator needs some time for
performing the changes. During this time the fix frequency and voltage protections (connected to nominal
values) must be blocked.
The time need for blocking of these protections is set by setpoint:
ForceBlock6Del 0-60s (step 0,1s) FV (Delays/Timers Group)
HINT
With larger frequency range the regulation can be rougher, in this case the AC/DC inverter is expected.
WARNING!
Used generator should be designed for variable rotation.
With frequency changes the nominal value of Voltage must be also changed.
Force value – step by step guide
In this chapter there is complete step by step guide which shows how to use Force value function of the
controller.
Forcing of values is used to change particular setpoint temporarily by activation of related Binary Input. This
is used to change function of controller under given conditions (e.g. there are two different periods during the
day when Export limit given by distribution network is required or not).
WARNING!
Setpoints must not be written continuously (e.g. via Modbus connection)! If continuous change of setpoints
is required, combination of External values and Force value function needs to be used. The memory that
holds setpoints is designed for up to 105 writings. Than memory may be damaged!

Add or remove Force value
Change position of Force value functions (priority)
Change the name of the source setpoint
(available only for Force value 1-16 setpoints)
Select the value that should be forced (i.e.
the value of the particular setpoint)
Rename binary input that
triggers the forcing
ID of binary input
(1 for ForceValueIn 1 etc.)
Select source setpoint or value
Setpoints that are available for forcing may be identified by Force value button on the right side in GenConfig
(see the figure below).
When the button is clicked, Force value dialog appears.
For example if we add Force value:Force value 1 to be forced to ProcessControl:Export limit as value 0
(DISABLED) by Binary Input FORCEVALUEIN 1 we can change the function of Export limit from ENABLED to
DISABLED by activation of FORCEVALUEIN 1. It is possible to rename the setpoint to e.g.
Force value:ExportDisabled and Binary Input as well to e.g. DISABLEEXPLIM. The function will not change
(only the corresponding names).
It is possible to use several force value functions for one setpoint. If more than one forcing Binary Input is
active, the one with the highest position (lowest number in the Force value dialog) is used.
It is possible as well to use one Binary Input to force multiple setpoints (e.g. in case of complex function
change).
NOTE:
It is possible only to force value or setpoint in other setpoint if their dimension and range are the same (e.g.
only value with dimension in hours and which is Integer 16 to a setpoint with dimension hours and which is
as well Integer 16). You may use PLC block Convert to change the dimension and range if needed.

Values for continuous writing from external sources
This function is especially designed for continuous writing of setpoints from external sources (e.g. via
Modbus connection).
WARNING!
Setpoints must not be written continuously (e.g. via Modbus connection)! If continuous change of setpoints
is required, combination of External values and Force value function needs to be used. The memory that
holds setpoints is designed for up to 105 writings. Than memory may be damaged!
It is possible to use up to four different External values for continuous writing from external sources. The
values are adjusted by setpoints in Force value group. Default (also initial) value may be adjusted, rate of
change of ExtValueX (by Binary Inputs EXTVALUEX UP and EXTVALUEX DOWN) can be adjusted as well as
high and low limit of the value.
There are two way, how to adjust External values. One is using Binary Inputs mentioned above. Second one
is to write the value directly using e.g. Modbus. External values then may be converted using PLC block
convert and force into setpoint which is then continuously forced (note: NOT WRITTEN) by the value of
ExtValueX. This way internal memory is safe and no damage may occur.
External values are reverted back to their default (initial) value (given by corresponding setpoint) when
Binary Input for their reset is active (and they change to the previous value after Binary Input deactivates).
When the Binary Input is active the External value cannot be changed by Modbus writing or by using Binary
Inputs for up and down value.
NOTE:
External values are not available for external writing when any Binary Input (up, down or reset) related to
them is active.
Note also that when the controller is reset (powered down and up again), all external values are reverted
back to their default (initial) values.
HINT
For information on how to write (or read) objects from controller via Modbus, please refer to the latest
Communication guide for InteliGen and InteliSys.
User Buttons
There are several User Buttons available in the controller. It is possible to set them on Soft Buttons in
InteliVision 5 or 8.

PULSE ON
Pressing the button issues log. Binary Output USER BUTTON X to close for one second.
NOTE:
Repeated pressing of button during the closed period (one second) causes issuing other
puls of length of one second to be generated from the moment of button pushing.
Available functions for soft buttons are listed in the following table.
HINT
It is possible to lock User Button with password (go to tab Commands in GenConfig). User Buttons 1-5, 6-8
and 9-16 can be locked separately. It is also possible to use User Buttons in SCADA diagrams.
User Mask function
In GenConfig you can easily set any object in Screen Editor to show or hide based on activation of particular
Logical Binary Input available for users. Below, there is diagram showing the setup of User Mask function in
Screen Editor.

this object
NOTE:
Masking of screens in InteliVision 5 supports only Show function
Use also other masking functions (masking can react on several internal states, e.g. activation of Timers).
Remote Control Function
It is possible to remotely control several Binary Outputs in the controller. You can either use Remote
Switches tool in InteliMonitor (select Remote switches in menu for corresponding controller), import Remote
Switches tool to a SCADA diagram in Line Diagram Editor or use external device via Modbus (register
#46361 and command #26 (1A hex), for more information on Modbus please refer to the InteliGen/InteliSys
Communication guide).
Remote Switch will activate or deactivate depending on remote control so it can be used to manually control
devices, simulate malfunctions while commissioning etc.

VPIO module
Remote Switches may be easily used to trigger logical Binary Input function and all other related functions as
normal switch on Binary Input. Module VPIO (Virtual Peripheral Inputs- Outputs) can be added to
configuration and it will copy the state of Remote Switch on virtual output to its counterpart virtual input.
Refer to the figure below for example.
Virtual Peripheral Inputs-Outputs (VPIO) module
For the controller there are several modules available. One of them is Virtual Peripheral Inputs-Outputs
module which is particularly usefull for connection of logical Binary Output functions to logical Binary Input
functions. This way internal controller function may easily trigger other internal controller functions without
unnecessary wiring or usage of PLC functions.
Module is functioning the same way as normal module with 8 outputs and 8 inputs, but the difference is, that
each input copies its counterpart output. It is possible to select any logical Binary Output function for one of
the outputs of VPIO module. Inputs on VPIO module work the same way as standard input of the controller
(i.e. it can be assigned function and protection).
For example of this function please refer to the chapter Remote Control function.
Shared Inputs and Outputs
It is possible to share Binary and Analog values between all the controllers via CAN bus, thus saving
physical Inputs and Outputs and excess wiring.

Shared Binary Inputs and Outputs may be used exactly in the same way as standard physical Inputs and
Outputs. If SHBIN or SHAIN modules are configured, at least one corresponding module of SHBOUT or
SHAOUT (respectively) is needed. If it is not configured, corresponding protection appears because SHBIN
or SHAIN will be missing. See the figure below for more information.
CAUTION!
For proper function of Shared Binary and Analog Inputs and Outputs, only one source of Shared Binary or
Analog Outputs must be configured (i.e. it is not possible to configure in one controller SHBOUT1 and to
another one as well SHBOUT1).
HINT
Controller sends Shared Binary Outputs each 100ms if there are any changes in any bit position. If there are
no changes, controller sends the information with period 1s.

Distributed Binary Inputs and Outputs
It is possible to share Binary and Analog values between all the controllers via CAN bus, thus saving
physical Inputs and Outputs and excess wiring.
DISTBIN and DISTBOUT work in a different way than SHBIN and SHBOUT. Each controller has one pack of
eight DISTBOUT available (if not configured or no function is assigned to any output, it does not broadcast
them). The number of DISTBOUT module is not shown in the configuration and it is always corresponding to
the CAN address of the controller (e.g. the controller with address 5 will be broadcasting DISTBOUT-05
which can be received if module DISTBIN-05 is configured in another controller. Up to 32 DISTBIN modules
can be configured (meaning that the controller will be receiving all DISTBOUT from all the controller, even
his own).
It is not possible to change the name of DISTBIN inputs or add protections.
In the example below you can see 4 controllers with various DISTBIN and DISTBOUT configuration.
NOTE:
HINT
Controller sends Distributed Binary Outputs each 100ms if there are any changes in any bit position. If there
are no changes, controller sends the information with period 1s.
NOTE:
DISTBIN and DISTBOUT function is not available for IM-NT-GC and IG-NT(C)-GC controller.
NOTE:
DISTBIN and DISTBOUT function is conditioned by IGS-NT-LSM+PMS dongle.

The “Modbus Switches” contains of two groups of LBOs named “ModbusSw1” and “ModbusSw2”. Both
registers are available on Modbus for simple writing (using command 6 or 16). The particular bits of these
registers are available as binary status for universal use in logical binary outputs of the controller as
“ModbusSw1..ModbusSw32”. No password is required for writing of those registers. There are two Values
“ModbusSw1” and “ModbusSw2” in group “Log Bout” available for back-reading.
NOTE:
The LSB of ModbusSw1 (46337) corresponds with LBO “ModbusSw1”
The LSB of ModbusSw2 (46338) corresponds with LBO “ModbusSw17”
The Values ModbusSw1 and ModbusSw2 have the position of LSB opposite-wise.
Examples:
Power Formats
IGS-NT family allows user to choose from several Power Formats that affect dimensions in which values and
some setpoints are interpreted or adjusted. Power formats may be changed in Miscellaneous tab in
GenConfig. There are following Power Formats available:
1 kW kVAr kVA kX V
0,1 kW kVAr kVA kX V
0,01 MW MVAr MVA MX kV
0,01 MW MVAr MVA MX V
NOTE:
Range of some setpoints and values is changed significantly when different Power Formats are selected.
Last Power Format is designed to be used in combined Power/High Voltage and Low Voltage instalations.
High voltage is then interpreted in Volts (e.g. 33256V instead of 33kV).
Last two Power Formats can be used in combination on one CAN bus.
PLC functions
Following functions are available in IGS-NT-GeCon-MARINE firmware.

Multi language support
NT Family controllers support up to three Languages that is possible to switch during controller duty. Every
terminal (i.e. Remote display or PC-InteliMonitor) can be switched to different language. Use PC-GenConfig
- Translator tool to translate texts to another language.
Default application archives contain all texts in English only.
ECU interface customizing
The list of available ECU interfaces can be found in GenConfig / Modules / ECU list.
In sw GeCon is possible to configure the any ECU communicating via J1939, but controller can read
information only. Writing any information is not possible. ECUs comunicate via modbus are not supported.
Volt/PF control adjustment
IG-AVRi output connection
Every time refer to corresponding AVR manual before interface connecting. Use no droop AVR.
IG-AVRi-TRANS (AC power supply for AVRi) has to be supplied from gen-set voltage.
AVRi outputs can be connected as symmetrical: OUT1-OUT2 or unsymmetrical OUT1-OCOM or OUT2OCOM.
Potentiometer on the AVRi defines maximal OUT1, OUT2 voltage range.
Use symmetrical (OUT1,OUT2) AVRi output to connect the AVRi to AVR auxiliary voltage input.
Use unsymmetrical output if an external AVR potentiometer has to be replaced with AVRi.
AVRi output voltage should change generator voltage typically in range 10 % of Nominal voltage.

Voltage control adjustment
HINT:
To judge optimal adjusting induce generator voltage jumps by AVR DCout bias change or by Nominal
voltage change .
AVRi output OCOM is common output. GND was used instead of OCOM
PF control adjustment
The genset should be cca 30 % loaded in parallel to mains and baseload mode.
1) Set the same values PF gain, PF int as in voltage control loop.
2) Set Process control: #SysLdCtrl PtM = BASELOAD, #SysBaseLoad = 30 % of Nominal load,
#SysPFCtrl PtM = BASEPF, #SysPwrFactor = 1.0.
3) Start and synchronize the gen-set in MAN Mode by pressing GCB ON/OFF
4) When running in parallel 30% loaded increase slowly PF gain to unstable point and then decrease
value by 30 % to insure stable performance.
5) Adjust PF int (usually setting to 100% gives optimal performance).
Hint:
Inteli NT GeCon-MARINE SPI, SW Version 3.2, ©ComAp – July 2015

1) Set Voltage gain, Voltage int to zero and AVR DCout bias to 50%.
2) Start always with AVRi pot min adjustment (fully counterclockwise).
3) Start the gen-set in MAN Mode to nominal speed, without load.
4) Adjust generator voltage to nominal value by the potentiometer present on the AVR. If there is no
potentiometer on the AVR, use AVR DCout bias to adjust the nominal voltage.
5) Change AVR DCout bias to 0% and 100% to check generator voltage control range (typically 10
% of nominal voltage). Adjust voltage control range by AVRi trim.
6) Set AVR DCout bias to be Nominal voltage on generator (50%).
7) When gen-set is running unloaded increase carefully Voltage gain to unstable point and then
decrease value by 30 % to insure stable performance.
8) Adjust Voltage int (usually setting to 100% gives optimal performance).

Sync/load control adjustment
HINT:
Use isochronous speed governor.
Two wire shielded connection from IGS-NT SPEED GOVERNOR output (SG OUT, SG COM) to Speed
governor auxiliary input is recommended.
A full range change of the IGS-NT speed governor output (from SpeedGovLowLim to SpeedGovHiLim)
should cause 5-10% change of the engine speed (SpeedGovLowLim ~ 95% RPMnom, Speed gov bias ~
100% RPMnom, SpeedGovHiLim ~ 105% RPMnom.
IMPORTANT
Speed governor has to be adjusted for optimum performance before Sync / load control adjusting.
Check generator phase sequence before the first GCB connection.
SpeedRegChar = POSITIVE SpeedRegChar = NEGATIVE
Before optimal Sync/load setpoints adjusting disconnect GCB OPEN/CLOSE output or set Phase window =
0 to avoid paralleling.
Synchronizer adjustment
1) Start the engine in MAN Mode.
2) Set the engine RPM by speed trim on speed governor or by Speed gov bias and SpeedGovLowLim and
SpeedGovHiLim to Nominal frequency.
3) To start synchronizing press GCB ON/OFF button. GCB LED starts to flash to indicate synchronization.
To stop synchronization press again GCB ON/OFF .
Slip control adjusting:
4) Adjust Freq gain to unstable speed control and decrease value by 30 % to insure stable performance.
5) Adjust Freq int to stable (fast and smooth) slip control. Synchroscope movement on the controller
measure screen should slow down and stop (in any position, because Angle control is off).
Angle control adjusting:
6) Set Angle gain. Synchroscope on the controller measure screen should move slowly and stop in “up“
position. Set Angle gain to unstable value (synchroscope swings) and decrease value by 30 % to
insure stable performance.
Load control adjustment
Prior to Sync/Load control adjustment, the Volt/PF control has to be adjusted! Load control loop is active in
parallel to mains mode only (MCB feedback closed). Switch off other engines while adjusting.

1) Set #SysLdCtrl PtM = Baseload, set Baseload value to 30 % of Nominal power of one gen-set.
2) Set Load gain to the same value as Slip freq gain. Set Load int to zero.
3) Start the gen-set in MAN Mode, press GCB ON/OFF button to synchronize and close gen-set to mains.
4) When GCB is closed, gen-set load slowly increases to Base load value. Check that gen-set power is
positive (CT polarity!).
5) Increase Load gain to unstable load control and decrease value by 30 % to insure stable performance.
When Load int factor is set to zero gen-set load can differ from required Baseload.
6) To adjust and optimize Load int change several times Base load between 30 and 70 % of Nominal
power. Usually setting Load int to 100% gives optimal performance.
7) When gen-set is running full load check if
a. Speed governor output voltage value is not limited (not reached SpeedGovLowLim or
SpeedGovHiLim)
b. Speed governor actuator isn’t mechanically limited or operates in small section of throttle range.
Active and reactive power terminology
Mains
Exported active power is supplied to the mains. It is displayed in negative numbers e.g. –20kW.
Imported active power is consumed from the mains. It is displayed in positive numbers e.g. +20kW.
When reactive power is imported (>0) InteliMains-NT displays L (inductive) character of the load.
When reactive power is exported (<0) InteliMains-NT displays C (capacitive) character of the load.
Load
Active power consumed by Load is displayed in positive numbers e.g. 20kW.
When reactive power is positive (>0) InteliMains-NT displays L (inductive) character of the load.
When reactive power is negative (<0) InteliMains-NT displays C (capacitive) character of the load.
Genset
Generated active power is displayed in positive numbers e.g. 20kW.
When reactive power is positive (>0) IGS-NT displays L (inductive) character of the load.
When reactive power is negative (<0) IGS-NT displays C (capacitive) character of the load.
Synchronizer adjustment
7) Start the engine in SEM Mode.
8) Set the engine RPM by speed trim on speed governor or by Speed gov bias and SpeedGovLowLim and
SpeedGovHiLim to Nominal frequency.
9) To start synchronizing press GCB ON/OFF button. GCB LED starts to flash to indicate synchronization.
To stop synchronization press again GCB ON/OFF .

The gen-set can't be started again while there is a Slow stop alarm in the
Alarmlist.
Activates the output Common Stp as well as the standard alarm outputs.
Protection groups
There are two groups of protections in the controller: fix and customer configurable.
Protection types
Because of limited (adjustable) GeCon influence to the Engine and GCB (depends on configuration and
wiring) the GeCon protection system is more focused to fail indication. All Protection types are available
because of IGS-NT system compatibility even if some Protection types have the same result in GeCon (e.g.
BO, Stp, Sd).

Off Load
2
The event appears in the Alarmlist and is recorded into the history log. It
does not require confirmation, diappears by itself.
It causes immediate opening of the GCB. In AUT and SEM modes the genset remains running for 60 seconds and then it is stopped by the standard
stop sequence. In MAN mode the gen-set remains running until the
operator changes it's operational state manually.
If the controller is in AUT or SEM mode and all previously active Off load
alarms disappeared the gen-set is automatically started back and
connected to the load if the condition for the gen-set to be running persists
(e.g. Rem start/stop is active ..).
This event is used to put the gen-set temporarily off the load for any
reason.
Activates the output Common OfL.
Low Power
2
The event appears in the Alarmlist and is recorded into the history log. It
does not require confirmation, diappears by itself.
It causes reduction of the required gen-set load to the Min Power PtM
during parallel-to-mains operation or local baseload operation.
If all previously active Low power alarms disappeared the gen-set is
automatically ramped back to the original required load, which is given
according to the currently active load control mode (Load ctrl PtM) in PtM
operation.
Activates the output Common LoP.
This alarm type is not overriden by the input Sd Override.
Note:
Available in IS-NT only.
BrkOpen

Alarmlist.
Activates the output Common BO as well as the standard alarm outputs.
Mains Protect
2
The protection is only recorded into the history log.
In applications which control the MCB this protection causes opening of the
MCB. The gen-set can continue operation in island mode if required. The
MCB can be closed back as soon as there isn't any mains protection active
(including the built-in mains protections).
In applications which do not control the MCB this protection causes
opening of the GCB. The controller waits then for the MCB to open. After
that the gen-set can continue operation in island mode if required. As soon
as there isn't any mains protection active (including the built-in mains
protections) the GCB is opened again and the controller waits for the MCB
to close. After that the gen-set can continue operation in parallel-to-mains
mode if required.
Activates the output Common MP.
This alarm type is not overriden by the input Sd Override.
Sd Override
2
The alarm appears in the Alarmlist and is recorded into the history log.
It causes immediate opening of the GCB (without unloading) and engine
stays running (stop pulse is not send).
The gen-set can't be started again while there is a Sd override alarm in the
Alarmlist.
Activates the standard alarm outputs.
This alarm type is not overriden by the input Sd Override.

Shutdown override
If the Binary input Sd override is closed, all 2nd level protections are disabled to allow engine run in an
emergency situation, e.g. sprinkler devices power supply.

All protections are shown in Alarmlist and recorded into History, but the controller doesn’t stop the engine
because of them. If the input is deactivated and some protections are still active or not yet reset, the
controller starts to take these protections into account and consequently stops the engine.
Take in account, that the binary outputs, signalizing activation of the particular protection are active
independently on the state of BI: SdOverride.
Hint:
All 2nd level protections are locked out, except of these:
- Emergency stop
- Binary and analog protections configured as Sd override type. In fact this protection type means:
"Unoverridable shutdown", i.e. it works the same way as standard shutdown protection, however it
can not be overriden (blocked) by the Sd override input.

When closing the CB, the CB status LBO
switches over only when both feedbacks
are in correct position
Note:
In the following text, “CB” abbreviation is used for MCB or GCB respectively.
Related binary inputs:
- CB fdb – CB feedback binary input
- CB fdb neg – negative CB feedback binary input. Used for increasing the reliability of CB status
evaluated by the controller. In case that it is not configured, negative value of CB fdb is calculated
internally within the controller.
Related binary outputs:
- CB close/open – output for circuit breaker. Equals to 1 during the time when CB is requested o be
closed.
- CB ON coil – output for closing coil of the CB. 2s pulse (5s if synchronising is not provided by the
particular CB) is used for closing the CB.
- CB OFF coil – output for opening coil of the CB. 2s pulse (5s if synchronising is not provided by the
particular CB) is used for opening the CB.
- CB UV coil – output for undervoltage coil of the CB. Permanently active, 2s negative pulse (5s if
synchronising is not provided by the particular CB) is used for CB opening request
- CB status – output indicating CB status as evaluated by the controller. This signal is used for lighting
LEDs on the panel, switching the regulations, CB fail evaluation, etc.

Other CB fail reasons:
When the BO CB close/open is in steady state and CB feedback is changed, the CB fail is detected
immediately (no delay).
When the BO CB close/open opens, there is 5 resp. 2 sec delay for the breaker to respond before a CB
fail is detected. In such case, if CB OFF coil is used for opening the CB and CB fail occurs during
opening the CB, the signal CB OFF coil is automatically extended until the breaker opening is detected
(evaluated as CB status).

CAUTION!
Usage of any 3rd-party peripheral modules in cooperation with ComAp controller is not recommended.
ComAp can’t guarantee the proper function of controller with none-ComAp peripheral modules.
Analog outputs
IS-NT controller has one analogue output, free configurable. To this output there can be configured any
analogue value, which is in the controller. To scale the output use the internal calculator in the GenConfig
PC tool.
If the output range 4 to 20 mA is needed, the limits for analog output should be set according to an example
in the following table:

Setpoints
Password protection
Any setpoint can be password protected - 7 levels of password is available. The password is a four-digit
number. Only setpoints associated with the entered password level can be modified.
Even though one level may have been set from the front panel, the affected setpoints are not accessible
from InteliMonitor (direct or Modem) until this level is set in IMON (InteliMONitor). Setpoints opened from
front panel are automatically closed 15 minutes after the last key has been pressed or when wrong value of
password is set. Any password can be changed once that level password or higher has been entered.
The controller programming (configuration) requires the highest password - 7 level.
ProcessControl
BaseLoad [ kW – MW*]
This setpoint is used for adjusting of the requested gen-set power in Baseload mode, i.e. if the setpoint Load
ctrl PtM is set to BASELOAD
Step: 0,1 kW / 1 kW / 0,01 MW*
Range: 0,1 kW – 650,00 MW*
ForceValue possibility: No
*Note:
The actual setpoint units and range depend on setting of the Power format (see GenConfig manual).
Hint:
If you set this setpoint to a higher value than the system is available to produce, the total produced power is
limited with the sum of Nomin power setpoints of all gen-sets in the system.
Base PF [ ]
This setpoint is used for adjusting of the requested gen-set power factor value if the power factor control
mode is set to BASEPF (setpoint PF ctrl PtM).
Values over 1.00 mean capacitive load character, i.e. setting 0.95 means 0.95L and setting 1.05 means
0.95C.
Step: 0,01
Range: 0,60 - 1,20
Import load [ kW ]
This setpoint is used for adjusting of the requested mains import if the gen-set load control mode is set to
IMP/EXP (Load ctrl PtM = IMP/EXP)
This setpoint is also used for adjusting of the maximum allowed export if export limit function is active (Export
limit = ENABLED).
Range: -32000 .. 32000 [kW]
NOTE:
Negative value of import is export, i.e. the power flows into the mains.
NOTE:
The actual setpoint units and range depend on setting of the Power format in GenConfig.

Import PF [ - ]
The setpoint is used to adjust the requested power factor at the mains when PF ctrl PtM = PF-IM/EX. Values
over 1.00 mean capacitive load character.
Step: 0,01
Range: 0,60 - 1,20
EXAMPLE:
Setting 0.95 means 0.95L and setting 1.05 means 0.95C.

Force value possibility: Yes
I/E-Pm meas [ NONE / IM3 CT INPUT / ANALOG INPUT ]
Import / Export measurement selection when one of power I/E modes selected.
NONE No source for I/E active power measurement available. If selected, power control
defaults to Baseload (BASELOAD, ANEXT BASELOAD, T BY PWR).
IM3 CT INPUT Mains I/E active power (Pm) is measured and calculated from controller’s Im3
current terminal. The value is multiplied by 3 to estimate the aggregate mains
power.
ANALOG INPUT Mains I/E active power is measured by an external device and the controller
measures this value via analog input LdCtrl:I/E-Pm.
Hint:
Earth fault current protection may be used only if I/E-Pm meas = ANALOG INPUT or NONE.

NONE No source for I/E reactive power measurement available. If selected, power factor
control defaults to BasePF (BASEPF, ANEXT BASEPF).
IM3 CT INPUT Mains I/E reactive power (Qm) is measured and calculated from controller’s Im3
current terminal. The value is multiplied by 3 to estimate the aggregate mains
reactive power.
ANALOG INPUT Mains I/E reactive power is measured by an external device and the controller
measures this value via analog input PFCtrl:I/E-Qm.
Hint:
Earth fault current protection may be used only if I/E-Qm meas = ANALOG INPUT or NONE.
If I/E-Pm meas is set to IM3 CT INPUT, then I/E-Qm meas should be logically set to IM3 CT INPUT as well,
because IM3 CT INPUT is common input for both parameters.
PeakLevelStart [ kW – MW* ] (FV)
Load consumption level the gen-set has to stop at. Function is inactive when PeakAutS/Sdel = OFF. Genset

Hint:
To record the power derating activity into the History:
-Configure the binary output Derating X act to a virtual periphery input.
-Configure either “History record” or “Warning”-type alarm to this input to record power derating
activity in History and optionally to indicate it in Alarmlist.
Derated1 pwr [ % ] (FV)
Derated2 pwr [ % ] (FV)
The ratio of decreasing of the gen-set nominal power at DeratingX end level.
Step: 1 % of Nomin power
Range: 0 - 100 % of Nomin power
Force value possibility: Yes
Hints:
DeratedX pwr = 90% means the nominal power reduction to 90%, not by 90%.
Derating ratio is set to zero and functions are not active when Analog inputs PowerDeratingX are not
configured (e.g. in default configuration).
When Power derating function is active, the generator nominal power is decreased to DeratedX pwr and so
Overload protection (BOC Overload) is based on this Derated power!
The generator nominal power is reduced according to the bigger restriction – the more reduced channel out
of the two.
TempByPwr Treq [ °C ] (FV)

GenConfig SW.
LB/UART Log [ENABLED / DISABLED]
Enables history logging of IG-IB / I-LB connection.
Force value possibility: Yes
Hint:
If communication via IG-IB is interrupted for more than 5s, it is automatically terminated. If it is established
again after this period, it is considered as a newly created connection and a new record “Terminal” is done
into history in case of LB/UART Log = ENABLED. This may cause overfilling of the history in case of some
monitoring tools, e.g. InteliSupervisor.

FIXED
The ethernet connection is adjusted fixedly according to the setpoints IP address, Net
mask, Gateway IP, DNS IP. .
This method should be used for classic ethernet or Internet connection. When this type
of connection is opening the controller is specified by it's IP address. That means it
would be inconvenient if the IP address were not fixed (static).
AUTOMATIC
The ethernet connection settings is obtained automatically from the DHCP server.
The obtained settings is then copied to the related setpoints (it is not possible to set
those setpoints manually in this setting, for more information please see the following
setpoints: IP address, Net mask, Gateway IP and DNS IP). If the process of obtaining
the settings from DHCP server is not successful the value 000.000.000.000 is copied to
the setpoint IP address and the module continues trying to obtain the settings.
This method is beneficial for AirGate connection as it makes the connection very easy,
in fact "plug and play". When this type of connection is opening the controller is
specified by it's AirGate ID and the IP address does not play any role.
The setpoint selects function of the terminal address 122 at the CAN2 line. See the latest communication
guide for details about this topic.
CANAddrSwitch2
The setpoint selects function of the terminal address 125 at the CAN2 line. See the latest communication
guide for details about this topic.
IP address
In fixed settings mode this setpoint is used to adjust the IP address of the ethernet interface of the
controller. Ask your IT specialist for help with this setting.
In Automatic settings mode this setpoint is used to display the IP address, which has been assigned
by the DHCP server. It is not possible to change the setpoint value manually in this setting (the value
is immediately reverted back by controller communication module IB-COM).
IP Addr mode
The setpoint is used to select the method how the ethernet connection is adjusted.
CAUTION!
If you need to use fixed ethernet settings you should consult the proper setting with your IT specialist.

Net mask
DISABLED
This is a standard mode, in which the controller listens to the incoming traffic and answers
the TCP/IP queries addressed to him. This mode requires the controller to be accessible
from the remote device (PC), i.e. it must be accessible at a public and static IP address if
you want to connect to it from the Internet.
ENABLED
This mode uses the "AirGate" service, which hides all the issues with static/public address
into a black box and you do not need to take care about it. You just need only a
connection to the Internet. The AirGate server address is adjusted by the setpoint AirGate
addr.
In fixed settings mode this setpoint is used to adjust the network mask of the network segment
where the controller is connected.
In Automatic settings mode this setpoint is used to display the network mask which has been
assigned by the DHCP server. It is not possible to change the setpoint value manually in this setting
(the value is immediately reverted back by controller communication module IB-COM).
Gateway IP
In fixed settings mode this setpoint is used to adjust the IP address of the gateway of the network
segment where the controller is connected.
In Automatic settings mode this setpoint is used to display the gateway IP address which has been
assigned by the DHCP server. It is not possible to change the setpoint value manually in this setting
(the value is immediately reverted back by controller communication module IB-COM).
A gateway is a device which connects the respective segment with the other segments and/or Internet.
ComApProtoPort
Range [units] 1 .. 255 [-]
This setpoint is used to adjust the port, which is used for ethernet connection to a PC with any of ComAp PC
program (i.e. InteliMonitor, GenConfig). This setpoint should be adjusted to 23, which is the default port
used by all ComAp PC programs. A different value should be used only in special situations as e.g. sharing
one public IP address among many controllers or to overcome a firewall restrictions.

Proper setting of SMTP-related setpoints as well as controller mailbox are essential for sending alerts via e-
mails.
This setpoint is used for entering the domain name (e.g. smtp.yourprovider.com) or IP address (e.g.
74.125.39.109) of the SMTP server. Please ask your internet provider or IT manager for this information.
NOTE:
You may also use one of free SMTP servers, e.g. smtp.gmail.com. However, please note that some free
SMTP servers may cause delays (in hours..) when sending e-mails.
NOTE:
If you do not want to send active e-mails, you may leave this setpoint blank, as well as other setpoints
related to SMTP server and e-mail settings.
Contr mailbox
Range max. 32 characters
Enter an existing e-mail address into this setpoint. This address will be used as sender address in active
e-mails that will be sent from the controller. Do not enter your or other recipient's e-mail address.

Recipient's addresses are to be entered into the setpoints AcallCH1-Addr, AcallCH2-Addr and AcallCH3-
Addr.
NOTE:
Most of SMTP server will reject sending e-mails that contain nonexisting address in the sender address field.
Time zone
Range [units] - [-]
This setpoint is used to select the time zone where the controller is located. See your computer time zone
setting (click on the time indicator located in the rightmost position of the the windows task bar) if you are not
sure about your time zone.
NOTE:
If the time zone is not selected properly the active e-mails may contain incorrect information about sending
time, which may result in confusion when the respective problem actually occured.
DNS IP
Range [units] - [-]
In fixed settings mode this setpoint is used to adjust the domain name server (DNS), which is
needed to traslate domain names in e-mail addresses and server names into correct IP addresses.
In Automatic settings mode this setpoint is used to display DNS server, which has been assigned by
the DHCP server. It is not possible to change the setpoint value manually in this setting (the value is
immediately reverted back by controller communication module IB-COM).
ECU Diag (FV)
Range [units] DISABLED, ENABLED [-]
This setpoint is used to disable reading of diagnostic codes from the ECU if an external diagnostic tool is
connected to the engine.
A message ECU Diag disabled is displayed in the alarm list while ECU diagnostics is disabled.
SHxOcol detect [ DISABLED / ENABLED ]
This setpoint is used to enable/disable evaluation of collisions of virtual shared peripherial modules. A
collision means that there is more than one source (shared outputs module) active on the CAN2 bus.
NOTE:
In certain situations multiple sites with bus tie breakers may need to have more shared outputs sources as
the CAN bus line is in some points interrupted according to bus tie breakers position. Normally a collision
would be indicated if there were more sources on the bus and this setpoint can be used to disable the
evaluation of collisions in this special case.

Range [units] 0 .. 10000 [A]
This setpoint adjust the level of EarthFault Current when IDMT protection starts to get evaluated. Time of
evaluation of this protection is given by the setpoint 2EthFltCur del. When the EarthFault Current goes below
the level given by Nom EthFltCurr, protection starts decreasing its thermal counter. For more information
about this protection, refer to the setpoint 2EthFltCur del.
2EthFltCur del OFF, 0.1 .. 600.0 [s]
Range [units] OFF, 0.1 .. 600.0 [s]
This setpoint adjusts the reaction time of the IDMT EarthFault Current protection if the current is 200% of the
base level given by the setpoint Nom EthFltCurr.
The reaction time of the IDMT EarthFault Current protection is not fixed; it depends on how much is the
current above the limit (base level). The higher is the current the shorter the reaction time will be.
EXAMPLE OF IDMT CURRENT PROTECTION CURVE
NOTE:
The IDMT EarthFault Current protection is Breaker open and cool down (BO) type.
NOTE:
This protection's internal counter accumulates and it starts continuously decreasing when the EarthFault
Current goes below Nom EthFltCurr. This function prevents the protection from completely reseting when the
EarthFault Current goes below Nom EthFltCurr for only a short period of time. This behavior emulates circuitbreaker with thermal current protection.
ExcitationLoss [%]

Threshold for mains under voltage.
Step: 1 %
Range: 50 – Mains>V MP % of MainsNomV or MainsNomVph-ph respectively
Protection: Mains protection.
Force value possibility: Yes

All three phases are checked for mains voltage protection. Minimum or maximum out of three is used.
For high voltage applications, the MainsNomVph-ph can be used for nominal voltage setting.

Delay for mains under and over voltage protection.
Step: 0,02 s
Range: 0,00 – 600,00 s

Force value possibility: Yes
Hint:
If ENABLED is selected, it is likely that Vector shift protection will trip the MCB before other mains
protections. It senses the fast changes in mains voltage angle position, which occur with every mains failure,
even if the gen-set is not running in parallel with mains.
VectorS limit [ ]
Vector shift protection threshold level.
Step: 1°
Range: 1 – 45°
Hint:
To be sure of proper adjusting of VectorS limit, check Max VectorS value on the controller or PC software
screen. Max VectorS value is set to zero when transiting to parallel, and then accumulates the maximum
reached value (positive only) during parallel operation. Thus, during the normal operation, only the
“background noise” is accumulated (usually max 3°), and the protection level should be set to approximately
twice the value of this “noise”.
Mains V unbal [ % ]
Threshold for mains voltage unbalance alarm in % of nominal voltage. The voltage unbalance is calculated
as a maximum difference between phase voltages.
Step: 1%
Range: 0 – 200% of MainsNomV or MainsNomVph-ph respectively
Mains Vunb del [ s ]
Delay for mains voltage unbalance alarm.
Step: 0,1s
Range: 0 – 600,0 s

Force value: Yes
Hint:
If you want to lock out the GCB closing during synchronizing loop test, set Phase window = 0. This allows the
control loop to be tested while actual GCB closing is blocked.

Force value: Yes
SpdGovPWM rate [ Hz ]
Pulse-Width Modulation rate of the Speed Regulator pulse output.
Step: 1 Hz
Range: 500 – 3000 Hz
Hint:
This adjusting can be used for some Cummins and CAT engines speed governor interfaces. We recommend
to keep the default setting (1200 Hz) for all other speed governor types (coming out through the analog
interface +/- 10V).

Step: 0,1 %
Range: 0 – 200,0 %
Load int [ % ]
Relative integration factor of power control loop.
Step: 1 %
Range: 0 – 100 %
Hint:
Load gain and Load int setpoints are active only when gen-set operates in parallel to the mains, when GCB
and MCB are closed. This is valid for both single and multiple applications.
RampStartLevel [ % ]
Value of initial load, on which starts the load ramping according to Load ramp setting.
Step: 1 %
Range: 0 – 100 %
GCB open level [ % ] (FV)
Power level for opening the GCB while soft unload is in progress. If this level isn’t reached, the GCB opens
after GCB open del time.Setting = NO LEVEL disables this GCB open criteria.
Step: % of Nomin power
Range: NO LEVEL, 1 to 100 %
GCB open del [ s ] (FV)
The timeout to unload the gen-set. Should the load ramp fail to bring the gen-set power down to GCB open
level to allow the opening of GCB, the breaker will open after GCB open del. Setting = NO TIMEOUT
disables this GCB open timeout criteria.
Step: 1 s
Range: Load ramp – 1800, NO TIMEOUT
Force value: Yes
Hint:
It is possible to open GCB by panel button or externally.
Sync timeout [ s ] (FV)
Maximum allowed time for forward or reverse synchronization.
Step: 1 s
Range: 1 – 1800 s, NO TIMEOUT
Hint:
If the synchronizing does not succeed within (Sync timeout / 10, but minimum 60) s, the speed regulator
output is reset and synchronisation is automatically started again. So if you set the Sync timeout to
sufficiently high value, the synchronizing cycle can be internally repeated up to 10 times.

If NO TIMEOUT is selected, then the time for synchronizing has no limitation and can only be interrupted by
pressing the GCB or STOP button in SEM mode or removing a corresponding request input in AUT mode. In
the NO TIMEOUT case, the synchronization is restarted every 1800 / 10 = 180 s.

voltage or to match voltage during synchronizing. Voltage loop operates as well in single island operation.
PF gain [ % ]
Gain of power factor control loop.
Step: 0,1 %
Range: 0,0 – 200,0 %
PF int [ % ]
Relative integration factor of power factor control loop. Increasing of integration value causes quicker
response.

Force value
Force value 1-16 [ X ]
„Source“ setpoints containing the alternative values for selected „target“ setpoints. The setpoint with index X
corresponds to the Force value Xth function. Procedure description see in GenConfig-x.y User guide.
Hint:
As the “source” for Force value channel can be used any compatible value in the controller (in general all
values and setpoints of types integer8,16,32). In that case the corresponding Force value X setpoint is
unused on that channel.
ExtValue1LoLim [ X ]
ExtValue2LoLim [ X ]
ExtValue3LoLim [ X ]
ExtValue4LoLim [ X ]
ExtValueX low limit. The value is not decreased under this limit, even if the request still exists (via binary
input ExtValueX down).
Step: 1 X
Range: -32000 – ExtValueXHiLim X
ExtValue1HiLim [ X ]
ExtValue2HiLim [ X ]
ExtValue3HiLim [ X ]
ExtValue4HiLim [ X ]
ExtValueX high limit. The value is not increased above this limit, even if the request still exists (via binary
input ExtValueX up).
Step: 1 X
Range: ExtValueXLoLim – 32000 X
ExtValue1 rate [ X/s ] (FV)
ExtValue2 rate [ X/s ] (FV)
ExtValue3 rate [ X/s ] (FV)

ExtValueX rate of change per second. If the binary input ExtValueX down or ExtValueX up is active, the
value is changed according to this rate.
Step: 1 X/s
Range: 1 – 10000 X/s
Hint:
If binary input ExtValueXreset is active, the corresponding ExtValueX is held at its default value, regardless
of the activity of inputs Up and Down and regardless of incoming external set commands.
Using this function in combination with Force value you can externally control selected setpoints’ values and
achieve some special behaviour of the controller.

ExtValueX default (starting) value. If ExtValueX is changed from this default value using Modbus command,
the new value is kept in ExtValueX until another command arrives or until the controller has been switched
off. If the binary input ExtValueXreset is active, the ExtValueX is held at this value regardless of other
conditions.
