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.
BO: Start pulse, Stop pulse - for sending Start and Stop signals
Speed control (during synchronisation, regulation):
BO: Speed Up, Speed Down or Aout SG out
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)

For the IGS-NT-GeCon-MARINE is possible to use IGS-NT-LSM+PMS or IGS-NT-GeCon-LSM+PMS dongle
which enables the Load sharing and Power management functions. (both types of dongles have the same
function)
Modified setpoints
Below mentioned are GeCon specific setpoints only.
Hint:
All above mentioned setpoints can be Forced by Binary input(s) to another value (or switched between
ENABLED and DISABLED).
Based on setpoint settings there are three possible operational modes HAND – SEM - AUT:
Hint:
It is possible to configure (Force value) “HAND” – SEM switching via Binary input.
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.

MCU
In MANual mode, the controller evaluates configured protections only(when LBI:ReadyToLoad=1 only). All
regulation loops are disabled, not active. Controller’s state changes based on sensed signals ReadyToLoad
and GCB feedback. In case of some active protection, this is signalized by appropriate binary outputs.
Engine cannot be started from GeCon, GeCon cannot close the GCB, etc..,only opens GCB in cause SD
alarm and Setpoint:Protection mode:ACTIVE.
Controller flow chart in MAN mode
HAND mode
Hand mode is a special type of SEM mode. In Hand mode, the panel Start, Stop buttons are not working,
GCB is supposed to be controlled externally. The Hand mode is achieved by setpoints adjustment - see the
following picture.
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)
Engine start or Power management is activated from GeCon BI: Sys start/stop
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 starts synchronizing and is loaded/unloaded automatically based on
o Power management setting
o GeCon BI: Sys start/stop
GeCon will stop engine started from engine controller when BI Sys start/stop or due to Power
management function.
Controller flow chart in AUT mode:
Automatic gen-set start / stop function based on load changes and/or Running hours or Generator size.
Following functions are available:
Power management in kW
Guarantees adjustable load reserve (load step) in kW. Suitable for load demand-based optimization.
Activation: #Pwr mgmt mode = ABS (kW)
Power management in kVA
Guarantees adjustable load reserve (load step) in kVA. Suitable for generator- or busbar dimensioningbased optimization.
Activation: #Pwr mgmt mode = ABS (kVA)
Relative power management in %
Guarantees that the engines will be not continuously loaded more than to a certain level, leaving less than
selected relative load reserve. Suitable for engine life-based optimization.
Activation: #Pwr mgmt mode = REL (%)
Basic settings:
Contr.addr = 1
Pwr management:
#Pwr mgmt mode = RUN HOURS EQU
Priority ctrl = MASTER
RunHoursBase = 100 h
#RunHrsMaxDiff = 10 h

- Power management of two or more gen-set groups (bus tie support).
CAUTION!
The function of the controller is designed to handle the maximum sum of nominal power at 32000kW
(3200.0kW, 320.00MW depending on the power format in the controller). If the sum of nominal power of all
gen-sets connected to the intercontroller CAN exceeds these values the power format needs to be changed
accordingly.
Example: There are 20 gen-sets each with 2000kW of nominal power. The sum of the nominal power is
40000kW. Therefore the power format in kW cannot be used because the sum exceeds 32767. Therefore
power format in MW needs to be chosen because the sum in MW is 40MW (it does not exceeds 320.00MW).
Running hours balancing
The gen-sets priorities are automatically swapped to balance engine running hours. Up to 32 controllers are
supported.
Activation: #PriorAutoSwap = RUN HOURS EQU
Important setpoints: RunHoursBase , #RunHrsMaxDiff
Different sized engines (Load demand) swap
Three running engines (priorities) are swapped based on load demand (one “small” engine runs on “small”
load and swaps to another one “big” engine that runs when load increases).

Important setpoints: Control group, GroupLinkLeft, GroupLinkRight
When a Bus-tie disconnects the gen-set group the Power management and Load and Var share can operate
separately on each of them.
To enable the independent Pwr management, Load and Var sharing between the gensets, group of gensets
splitted by bus tie breaker, configure the setpoints as depicted on this picture.
When controler detects no voltage (any bus phase voltage is below 15 VAC) on the bus for the time
„DeadBusSTdel”, then this function activates local start command, starts the gen-set, and connects it to the
bus.
When the function Dead Bus Start is evaluated, LBO:Dead Bus Start is activated.
When LBO:Dead Bus Start=1 then Power management system is internally DEACTIVATED – all gensets with active LBO:DeadBusStart are started and connected to the bus (and run in loadsharing).
Activation and deactivation of this function is written to the history.
For deactivation of this function is necessary to switch to SEM mode and confirm the DeadBusStart alarm.
DeadBusStart function works in AUT mode only.
Function is available in MINT aplication.
Load shedding
Load shedding fiction 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.
If no Load Shedding outputs are configured, there is no record to history and no screen timer indication of
the activity of this function.
On the following pictures, the generator current load shedding is depicted. The current is evaluated from all 3
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.
Standard isochronous Load Sharing and VAr Sharing are based on CAN
intercontroller communication.
DROOP
Load Sharing and VAr Sharing regulations are based on droop. Requested power of
each gen-set is calculated based on bus voltage and bus frequency.
EMERG DROOP
Load Sharing and VAr Sharing regulation are based on standard CAN intercontroller
communication, but can be conditionally switched to droop. All controllers are
continually checking the CAN16/CAN32 register (value in group “Info”) to see witch
addresses are they in cooperation (use the LBI EmergDroopEnab to confirm the
supervised constalation of addresses on CAN). In case of lost of any controller from
CAN the regulations are automatically switched to droop (yellow alarm EmergDroop act appears in alarm list, message EmergDROOPon is writen in history). Load Sharing
and VAr Sharing regulation are switched back to the standard mode 60 s after the
constalation of addresses on CAN returns back to the original state (message
EmergDROOPoff is written in history, alarm EmergDroop act has to be confirmed
manually). The purpose of this function is protection against the cut off the CAN
intercontroller line.
Sync/load ctrl: Load droop, LdDroopOffset
Load droop
This setpoint defines the slope of the load droop correlation. The slope is set as a
droop of frequency in percentages of the requested frequency (Basic settings:Nominal freq + Nom frq offset) on the range of the requested power from 0 to 100% of
Basic settings: Nomin power.
LdDroopOffset
This setpoint defines the value of requested power on the requested frequency (Basic
settings: Nominal freq + Nom frq offset). Allows to shift the droop correlation line up
or down.
DROOP
The droop regulation of kW/kVAr is the alternative to the isochronous Load Sharing and VAr Sharing. In the
isochronous regulation are all information about the kW/kVAr shared via intercontroller communication line
whereas in droop no intercontroller communication is needed. The droop regulation is based on voltage and
frequency which are measured on the common bus. The requested kW/kVAr are calculated in each
controller from the actual bus voltage and bus frequency. This principle of regulation needs the voltage and
frequency beeing changing within defined limits. Type of regulation depends on settings of setpoint
ProcCrtlMulti: Reg kW/kVAr.
Load Sharing in droop
Characteristics of Load Sharing in droop are given by settings of these parameters:
This setpoint defines the slope of the VAr droop correlation. The slope is set as a
droop of voltage in percentages of the generator nominal voltage (Basic settings:GenNomV) on the range of the requested reactive power from 0 to 100% of nominal
reactive power (value of nominal reactive power is not given by setpoint but it is
calculated from setpoint Nomin power whilst the PF=0,8).
VArDroopOffset
This setpoint defines the value of requested reactive power on the nominal voltage
(Basic settings: GenNomV). Allows to shift the droop correlation line up or down.
Characteristics of VAr Sharing in droop are given by settings of these parameters:
Example: VAr droop = 4%, VArDroopOffset = 50% (75%)
Hint:
Droop mode allows cooperation of gen-set equipped by ComAp control system with gen-set equipped by any
third party control system. The steady bus voltage and bus frequency has to be regulated by this third party
control system. Active and reactive power of gen-set equipped by ComAp controller is kept on values given
by droop settings.
Over frequency and under frequency protections are active in droop. Be aware that the gen-set frequency in
droop can cross the levels of these protections. The force value on the under/over frequency protection limits
can be used if it is needed to set the different limits in droop.
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 opened (no actions).
Exceptions are Emergency Stop and Sd override alarms type.
External breaker control
This application accepts external breaker control in these situations:
MINT application:
Mode:MAN, SEM
External breaker control is accepted only when LBI:ReadyToLoad=1.
Exceptions:
If the BUS voltage is >15V and GCBfdb=1 and LBI:ReadyToLoad=0 then BO GCB Fail and History
record are performed.
SPtM application:
Mode:SEM
External MCB control is accepted
External GCB control is accepted only when LBI:ReadyToLoad=1.
Exceptions:
If the Mains parameters are out of limits (voltage and frequency) and GCB and MCB are closed
and LBI:ReadyToLoad=1 – external control is not accepted – Wrn MCB fail and Wrn GCB fail are
evaluated.
If the Mains voltage is > 15V and MCBfdb=1 and GCBfdb=1 and LBI:ReadyToLoad=0 then BO
GCB Fail and History record are performed.
SPI application:
Mode: SEM
External GCB control is accepted only when LBI:ReadyToLoad=1.
If the Mains parameters are out of limits (voltage and frequency) and GCB and MCB are closed
and LBI:ReadyToLoad=1 – external control is not accepted – Wrn MCB fail and Wrn GCB fail are
evaluated.
If the Mains voltage is > 15V and MCBfdb=1 and GCBfdb=1 and LBI:ReadyToLoad=0 then BO
GCB Fail and History record are performed.
Heavy consumers support
On ship are ussualy several heavy consumers which are connected to power bus only for limited
time. Before connecting is necessary to start more genset or easily increase actual load reserve for
covering the connection of heavy consumer.
LBI: HeavyConsumer1 (request for increasing load reserve before Heavy consumer connection)
Confirmation/feedback for Heavy consumer connection
LBO: HeavyCons fdb1 (after activation the Heavy consumer connection is possible)
How it works:
1) Before Heavy consumer connection – the request is activated (LBI: HeavyConsumer1)
2) When LBI: HeavyConsumer1 is activated then size of consumer (Setpoints:
HeavyConsumer1) is added to actual load reserve.
3) When the load reserve is increased (Syst res OK is activated) then HeavyCons fdb1 is
activated.
4) Based on the HeavyCons fdb1=1 the user can connect HeavyConsumer1 to bus.
CAUTION!
The user must ensure that each heavy consumer will have the same size over all controllers (it means that
HeavyConsumer1 has the size in controller #1 and #2.) (these setpoints are not shared)
Each controller counts level for start and stop (in power management system) locally, so user must ensure
correct activation of Heavy consumer inputs in all controllers (for example via Share Inputs/Outputs).
Solution is shown on the picture:
After connection of bow thruster to the bus it can be loaded from 0-100% variously acording to the
current maneuvers of ship.
In this case the request (increasing of actual Load reserve) must stay active (LBI:
HeavyConsumer1=1) all the time during connection of bow thruster to bus
Compressor
Compressor usually work ON/OFF (with unchanging load)
So after connection of compressor to the bus (and its activation) the load of Compressor is added
to current load on the bus and the user can deactivated the request (LBI: HeavyConsumer1->0),
because compressor has stable load which was currently connected.
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.
In generator is induced magnetic flux, which is almost constant in various RPM.
It is necessary to change nominal frequency together with nominal voltage – due to their
dependence.
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.
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
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!
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.
Pressing the button changes the state of log. Binary Output USER BUTTON X to closed.
When the output is closed and the button is pressed state is not changed.
OFF
Pressing the button changes the state of log. Binary Output USER BUTTON X to opened.
When the output is opened and the button is pressed state is not changed.
ON/OFF
Pressing the button changes the state of log. Binary Output USER BUTTON X to opened or
closed depending on previous state (it is changed to the opposite state).
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.
