WARNING VERY IMPORTANT !! !
Be aware that the binary outputs can change state during and after sof twarereprogramming (before the controller is used again ensure that the proper
configuration and setpoint settings are set in the controller)!!!
Be aware that gen-set can automatically or remotely start !!!
Switch the controller to MAN mode and disconnect the Binary outputs Starter and Fuelto avoid unexpected automatic start of gen-set and GCB closing.
!!! CAUTION !!!
Dangerous voltage
The terminals for voltage and current measurement should never be touched.Properly connect the grounding terminals.
Do not disconnect the CT terminals for any reason.
Adjust set points
All setpoints are preadjusted to their typical values. But the set points in the Basic settings settingsgroup !!must!!be adjusted before the first startup of the gen-set.
!! ! WRONG ADJUSTMENT OF BASIC PARAMETERSCAN DESTROY THE GEN-SET !!!

General description
Descript ion of the control ler system (with all options)
NT Family controllers are comprehensive AMF-controllers for single and multiple generating sets operatingin stand-by or parallel modes. A modular construction allow upgrades to different levels of complexity inorder to provide the best solution for various customer applications.NT Family controllers are equipped with a powerful graphic display showing icons, symbols and bar-graphsfor 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, thenstops the engine on external signal or by pressing push buttons.Parallel to the Mains operation is a standard feature. Isolated parallel and Power Management Systemsupport are optional. Forward and reverse synchronizing, Generator protections, Mains protection includingvector shift, load and power factor control are the major functions provided. Interfacing to foreignsynchronizers and load sharers is supported. Regarding the measurement inputs, the controller providesTrue RMS method for voltage, current and power measurement.
The key feature of the controller is its easy-to-use operation and installation. Predefined configurations fortypical applications are available as well as user-defined configurations for special applications.

Functions
OFF-MAN-AUT mode
OFF modeOutputs STARTER, GCB CLOSE/OPEN and FUEL SOLENOID are not energized.
Gen-set cannot be started. If START,STOP,GCB ON/OFF buttons are pressed the controller will not
respond.When the gen-set is running it is not possible to switch directly to OFF mode. First you have to stop theengine.
MAN mode
1) START - starts the gen-set.
2) GCB ON/OFF
If generator voltage is out of the limits (adjusted in the set point group Gener protect) controller doesnot respond to the GCB ON/OFF
a) controller closes GCB to dead bus.b) controller starts GCB synchronizing when bus voltage is OK and MCB is closed or when other
gen-set(s) provide healthy voltage to the bus. Closes the GCB when synchronized and staysrunning in parallel (island or mains parallel).
c) Unloads gen-set and opens the GCB if gen-set was running in parallel to the mains or to othergen-set(s).
3) STOP
a) When gen-set is running in parallel: transfers the load to the mains or to other gen-set(s), opensGCB, goes into cooling state and stops the engine.
b) When gen-set is running in single island (or in general there is no mains and no other gen-set(s)to transfer the load to): opens GCB, goes into cooling state and stops the engine.
c) When engine is running unloaded: activates cooling sequence and then stops the engine.d) During cooling state causes immediate engine stop.
Hint:The gen-set is permitted to run unloaded for unlimited time.Controller does not automatically start the gen-set when SYS START/STOP input is closed.Load control type in mains parallel depends on ProcessControl: #SysLdCtrlPtM= BASELOAD orLDSHARING setpoint.
SEM
In SEM mode, pressing of START or STOP buttons performs a predefined sequence:
1) START starts the engine, synchronizes and runs in parallel.
2) STOP softly unloads the gen-set, opens GCB, provides cooldown and stops the engine.
AUT mode1) All gen-sets necessary to cover selected LoadRes strt are started when binary input SYS START/STOP
is closed and Pwr managementis ENABLED. Power management can be based on kW, kVA or onrelative % reserve.a) 1 sec delayed when MCB FEEDBACK binary input is closed (mains parallel)b) delayed #SysAMFstrt delwhen MCB FEEDBACK binary input is opened start to island parallel
(multi AMF) situation2) The first gen-set closes the GCB to the dead bus, the rest are synchronized to the bus.3) When all necessary gen-sets are connected to the bus and LoadRes strt is achieved, SYST RES OK
output is closed. Output could be used to close the MGCB (Master GCB).4) Total load and power factor are shared between parallel operating gen-sets.5) Close input LOAD RESERVE 2 (or 3 or 4) and use setpoint LoadRes strt2(or 3 or 4) to switch to another
load reserve setting. E.g. high load reserve during system start to be able to switch-on big devices, thenduring normal operation lower reserve to save engines (and fuel).

6) If total load increases and selected LoadRes strt is no more fulfilled, after a Next start del next readygen-set with the highest priority (lowest priority number) is started and synchronized to the bus.
7) If load decreases and selected LoadRes stp is exceeded, after a Next stop del the running gen-set withthe lowest priority is unloaded, got off line, cooled and stopped.
8) Complete gen-sets group stops when binary input SYS START/STOP opens. If the input MCBFEEDBACK is closed (gen-sets are in parallel to mains) controllers softly transfer the load to the mains.When gen-set is unloaded (see GCB open levelor GCB open del) opens the output GCB
CLOSE/OPEN.9) The Running hours balancing or Load demand engines swap can be activated in power management.Hint:
Controller does not respond to GCB ON/OFF , STOP, START buttons and corresponding remote
InteliMonitor or Modbus commands in AUT mode.
Set Basic setting: FltRes GoToMAN= ENABLED to avoid automatic engine start when pressing FAULT
RESET after any 2nd
level alarm (Shutdown, Slow stop, Breaker Open&Cooldown).

Load sheddingAll 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 SEM / AUT mode.b) When MCB opens from parallel to mains operation in SEM / AUT mode.c) Before MCB is opened in MAN mode by button.
The load shedding function is active in all controller modes except OFF.Load shedding has three steps and each step is linked with its own Load shed x binary output. There is onlyone load shed level and delay for all three steps as well as recon level and delay. Load shed can only movefrom one step to the next, e.g. No LoadShed to LdShed S1 to LdShed S2 to LdShed S3 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 levelat that moment.
Hint:If no Load Shedding outputs are configured, there is no record to history and no scrren timer indication of theactivity of this function.

System Base loadGen-set group is controlled on constant (or adjustable) power. The Baseload value can by changed bysetpoint or via analog input.Important setpoints: ProcessControl: #SysLdCtrlPtM= BASELOAD; #SysBaseload; SysBaseLdMode.
Local BaseloadSelected gen-set from island or mains parallel running group can be loaded to constant LocalBaseloadvalue. This engine is taken out from Load sharing and Power management. LocalBaseloadvalue is reducedonly when common group (actual) load is lower than this value. The gen-sets in the group will try to matchtheir LocalBaseloads (when more than one) based on their controller addresses, so the first limited would bethe one with the highest CAN address. I.e. this function will switch-off automatically in one or more
controllers if there is not enough load to cover all the requested LocalBaseloads.Important setpoints: ProcessControl: LocalBaseload.

Binary Inputs - Control
Sys start/stopIf the input closes, the controller may start the engine (in AUT mode only). Request to start depends on stateof setpoint Pwr management:Pwr managementstate and, if ENABLED, on the actual need of load reserve.I.e. all controllers in the system should have their Sys start/stop inputs active, but it doesnt mean that allengines are running.If Pwr management:Pwr managementis DISABLED, the closed input requests the engine to startregardless of the load reserves.Gen-set is running both in mains parallel or island parallel (depends on mains condition). Reaction on input
state change is delayed by setpoints #SysAMFStrtDel/ #SysAMFStopDelin island mode, by 1 sec in mainsparallel mode (= input MCB feedback active).
Emergency stopIf the input is activated, engine shutdown is immediately issued. It has a character of a Shutdown -protection type, however some special behaviour follows in the case of its activation:
- Outputs Ignition, Ventilation, Cooling pump, Prelubr pump are switched off, regardless of the enginestate.
- This input cannot be overridden with the input Sd override.Hint:Alarm type is set to No protection, as this input itself creates the shutdown protection.Input is inverted (= normally closed) in default configuration to achieve maximum security (broken wire).

Nominal speedIf the input is closed, the controller forces the engine immediately to the Running state, bypassing the Idletimesetting and shortening the start-up procedure.
Hint:
Use this input if you want to shorten the start-up procedure in an AMF situation.
PrestartBypassIf the input is closd, the controller bypasses the Prestart timeand activates the Starter output immediately.Hint:Use this input to bypass the pre-glow / prelubrication time in the case that the engine has run a short timebefore.
Oil pressBehavior for Inverted = Open to activate configuration:Binary input must be closed when engine is not running and opened when it is running. "Sd Oil press B" isactivated when input is opened on not running engine (still engine condition) or when stays closed for time
period set by Engine protect: RunOnlyBlkDel1after engine start. "Sd Oil press B" protection is not activewhen input is not configured.
Sd overrideIf the input is closed, all 2
ndlevel 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 doesnt stop the enginedue to their occurence. If the input is deactivated and some protections are still active or not yet reset, thecontroller starts to take these protections into account and consequently stops the engine.Hint:All 2
ndlevel protections are locked out, except of:
- Emergency stop- Overspeed
- Underspeed (only if Fuel solenoid= GAS ENGINE)
Emerg. manualThe controller behaves like when switched to OFF mode if input is closed. Opens all binary outputs Fuelsolenoid, Cooling pump signals, etc... except:
Stop solenoid output does not close.The output terminals that are configured with inversion are closed.
Detection of "running engine" condition and subsequent alarm message "Sd Stop fail" is blocked. Thecontroller shows "Emerg Man" state and the engine can not be started. Generator current and power(energy) measurement is active in this mode, regardless of the actual state of the engine.After the binary input EMERG. MANUAL is open again, the controller recovers to previous mode and
behaves according to the actual situation. Should the engine run and any of the conditions to start the enginewas active, it will keep the engine running.Function is active in any controller mode and activation of this input is written to history.Hint:The function is intended especially for Marine gen-sets which are supposed to be started manually while thecontroller has no power supply. To recover successfully from this state, only the signals Stop solenoid, GCBON/OFF coil should be used for engine and breaker control, as the other outputs are continuous activeduring engine run (e.g. Fuel solenoid) and it is not possible to switch them between more control sources.

RunIndication1
RunIndication 2
RunIndication 3Any of three binary inputs can be used for engine running indication e.g. via Oil pressure contact. Active
Running indication blocks engine start (to avoid starter damage).
AccessLock intIf the input is closed, no setpoints can be adjusted and no commands can be issued from the controller frontpanel.Hint:As the controller mode (OFF-MAN-AUT-TEST) is one of the setpoints, not even that can be changed.The START, STOP, FAULT RESET and other control buttons are disabled as well.
AccessLock D#2If the input is closed, no setpoints can be adjusted and no commands can be issued from IG/IS-Display #2.
AccessLock D#3If the input is closed, no setpoints can be adjusted and no commands can be issued from IS-Display #3.
AccessLock extIf the input is closed, no setpoints can be adjusted and no commands can be issued from any externalterminal = via direct/modem/internet connection to the controller.Hint:Use these inputs to lock out the selected terminals for setpoint changes and commands. Such a terminal canonly be used for monitoring.
Remote OFFActive binary input forces the controller mode to OFF. When opened the controller is switched to previousmode.If the engine is running, the active input has no effect. The controller switches to OFF mode only after theengine has been stopped.Hint:Use this input to block the engine start during service.
Remote MANActive binary input forces the controller mode to MAN.
Remote AUTActive binary input forces the controller mode to AUT.Hint:Use this input to switch the controller to automatic operation, e.g. using the external key switch.

When not configured or not active, setpoint set #LoadResStrt 1+#LoadResStop 1(#%LdResStrt 1+ #%LdResStop 1)is used.Hint:All controllers operating in Power management must have the same Load reserves selected.It is possible to use Virtual periphery to share the signals between more controllers on the CAN bus. In suchcase one controller is a server which physically has the signals connected and other controllers get thesesignals via CAN bus.Setpoint set selection depends on the #Pwr mgmt mode if set to ABS (kW or kVA), #LoadResStrt Xtypesetpoints are active, if set to REL (%), #%LdResStrt Xtype setpoints are active.
MinRun power 1
MinRun power 2
MinRun power 3When binary input MinRun power 1 or 2 or 3 is closed, the corresponding setpoint Pwr management:#MinRun power 1or 2or 3is selected. Higher index has higher priority when more these binary inputs areclosed together. When not configured or not active, minimal running power is 0, i.e. the system works onlybased on Load reserves.Hint:All controllers operating in Power management must have selected the same MinRun power input.It is possible to use Virtual periphery to share the signals between more controllers on the CAN bus. In thiscase one controller is a server which physically has the signals connected and other controllers get thesesignals via CAN bus.

Hint:Priority value is defined by setpoint Priority when all Priority switches are opened or not configured.The priority value defined by a combination of binary inputs Priority sw X is accepted with 1s delay. So if achange is made to more inputs simultaneously, it is accepted 1s after the last change sensed.
GroupLinkIf the input is configured, the group linking function is active, i.e. this controller becomes the status server fortwo groups of gen-sets and informs them about the BTB status.If this input is closed, the controller reports BTB status as closed, if open, the controller reports open BTBstatus.

StartButton
Binary input has the same function as Start button on the controller front panel. It is only active in MAN mode
and when setpoint Basic settings-> Local Buttonis set to EXTBUTTONS or BOTH.
StopButton
Binary input has the same function as Stop button on the controller front panel. It is only active in MAN mode
and when setpoint Basic settings-> Local Buttonis set to EXTBUTTONS or BOTH.
FaultResButton
Binary input has the same function as Fault reset button on the controller front panel.
To enable this function, set the setpoint Basic settings-> Local Buttonto EXTBUTTONS or BOTH.
HornResButton
Binary input has the same function as Horn reset button on the controller front panel.
GCBButton
Binary input has the same function as GCB button on the controller front panel. It is active in MAN and
TEST modes only. In TEST mode in some special cases only (see description of the TEST mode in chapterMode and functions description).Hint:All Binary inputs, which simulate controller front panel buttons, are edge (no level) sensitive, and they reacton the rising edge only. Minimal input pulse duration is 0,2 seconds.
ManualLdReconThe rising edge on this input switches the controller to the lower Load Shedding stage when Loadshedding:AutoLd recon=DISABLED and the load is under Load shedding:Ld recon level.
GCB disableThe input blocks the GCB closing, even if all other conditions (e.g. during synchronizing) for its closing are
fulfilled. Valid in all modes.Hint:If you want to lock out the GCB (or MCB) closing during synchronizing loop test, set Sync/Load ctr l:Phasewindow= 0. This allows the control loop to be tested while actual GCB (or MCB) closing is blocked.Conditions for closing:
1) voltage only on generator side of GCB (or MCB)2) voltage on both sides of GCB (or MCB) and all synchronizing conditions fulfilled.
Al t brightnessActive binary input switches controller display backlight to the alternative setting. Alternative intensity of thebacklight can be set independently using the controller panel buttons.Hint:
Input available in IG-NT/EE and modifications only. For IG-Display and IS-Display modules, this binary inputis located in the Power connector and its function is fixed (not configurable).
IssueActCallC1
IssueActCallC2
IssueActCallC3Rising edge on these binary inputs forces an active call to be issued via the corresponding channel.Hint:Can be used to send e.g. SMS in the case of a mains failure to report that the engine has successfullystarted (linked from the output Gen params OK) and later on to report that the engine has stopped again(linked from the inverted output Fuel solenoid).

ECUComFailBlckThe input blocks the issuing of the alarm in case of ECU communication failure.
StartblockingThe input blocks the engine start. If active, NotReady state is shown on the controller screen and a messageappears in the Alarmlist. As soon as input is deactivated, engine start is enabled again.
Hint:Use this input for cooperation with external supervisory device, such as PLC. It can prevent the engine to bestarted because of some reasons not known to the controller.
ECU StoppedEngEngine stop was activated in ECU, not from controller. The controller reflects this situation and also goes toStop to avoid an Underspeed alarm (and record in the Alarm list).
CtrlHBeat sensBI "CtrlHBeat sens"should be assigned to the output "CtrlHeartBeat" from the other controller. If input signaldoes not correspond to right form (log 1 / log 0 - 500 ms / 500 ms; +/- 100 ms), BO: "CtrlHBeat FD" (FailDetect) is activated. This BO can be used for primary controller blocking (switching to Emerg. manual,
disconnecting BO, ...) and mainly for disconnecting of BI "Emerg. manual" of this controller. What means thatthe backup controller assumes engine control.
Force value 1 16If any of the particular 16 input s is active, the Force value function on that corresponding channel getsactive, forcing an alternative value to the selected setpoint.

ExtValue4resetActive binary input causes ExtValueXto be reset and held at its default value, given by the setpointExtValueXdeflt.Hint:These inputs, if configured, do not block the external set commands (in contrast to ExtValueX up/ ExtValueXdown inputs). However, if the reset input is activated, the corresponding ExtValueXis reset to its default(ExtValueXdeflt) value. This default value is kept in ExtValueXuntil the reset input is deactivated, and theexternal set commands received meanwhile are ignored.

PulseCounter 4The inputs are linked with corresponding counters, which integrate the pulses sensed at these inputs. Eachrising edge of the signal at input increases the internal counter value.Hint:Pulse width (both high/low levels) must be at least 100 ms in order to be correctly sensed!Conversion ratio can be selected using the setpoints ConvCoefPulseX. The converted values are visible instatistics values PulseCounter X. These values can be reset using Statistics window in InteliMonitor.

Binary outputs Engine control
StarterThe output is intended to energize the starter motor during start sequence. The output opens ifthe Engine params:Starting RPMlevel is reached or maximum time of cranking is exceeded.Hint:If setpoint Engine params:Fuel solenoid= GAS ENGINE, the Starter output is active during Preventilationand Ventilation states as well to clean the engine off the unburned gas.
Fuel solenoidThe output controls the engine fuel valve. The setpoint Engine params: Fuel solenoidselects the outputbehaviour DIESEL or GAS ENGINE.
Stop solenoidThe output closes to activate the stop valve which interrupts the fuel input to the engine. The output isalways closed until the engine reaches 0 RPM and other engine running conditions disappear as well +additional 5s.The minimum time of activation is given by the Engine params:Stop timesetpoint, so even if all enginerunning conditions would disappear before, the Stop solenoid stays closed for that time.Hint:The output also closes if the engine begins to rotate spontaneously. It stays closed until still enginecondition is achieved + additional 5s.
Intended only for diesel engines, especially marine ones.
Stop pulse1s pulse for engine stop command, intended for ECU connection.
PrestartThe output closes prior to the engine start (time defined by Engine params:Prestart timesetpoint) andopens when Starter output opens the last time during starting sequence. During repeated crank attempts theoutput is constantly closed.The output can be used for pre-glow, pre-heat or prelubrication.
IgnitionIntended to activate the ignition unit of gas engines. The output closes immediately as engine runningcondition is detected and opens after the engine stop (still engine condition). The function is independenton other conditions, i.e. always if engine running is detected, the output activates.The output opens immediately when BI EMERGENCY STOP gets active.Hint:In case of repeated start:a) the output is switched on when RPM = 30 (it is fixed value)b) the output is switched off during Crank pause, but not until RPM fell down to 0c) the output is switched off by STOP command when RPM=0
VentilationIntended for the engine ventilator control. The output closes together with Prestart output and opens after the
engine stop (still engine condition).The output opens immediately when BI EMERGENCY STOP gets active or in OFF mode.

Idle/NominalThe output closes with transition from Starting (Idle) to Running state. It opens either with transition toCooling state (if Engine params:Cooling speed= IDLE), or after the command to stop the engine (if Engineparams:Cooling speed= NOMINAL).The closed output means that Nominal RPM are requested.Hint:
Connect this output to the speed governor to switch the requested speed: opened = IDLE RPM,closed=Nominal RPM.
Cooling pumpThe output closes when gen-set starts (engine started condition) and opens AfterCoolTimedelayed afterthe engine stop (still engine condition).The output opens immediately when BI EMERGENCY STOP gets active or in OFF mode.
Prelubr pumpIf engine is not running, the output closes with period Engine params:Prelubr pausefor Engine params:Prelubr time.The output opens immediately when BI EMERGENCY STOP gets active or in OFF mode.
Not lubricatedOutput indicates the lubrication cycle (PrelubrTime) is not finished after controller Switch-on or return fromOFF mode or deactivation of Emergency stop signal.
Binary outputs Breaker control
Hint:Controllers are protected against simultaneoous closing of two or more GCBs to dead bus by means ofhand-shake signals on CAN bus communication.
GCB close/open
The output controls the generator circuit breaker. It is intended for contactors provides a continual activesignal if GCB should be closed.
GCB ON coilThe pulse output for GCB closing. If GCB synchronizing is enabled, the pulse length is 2s, if not, pulse lengthis 5s.Hint:ON coil can only be closed if UV coil is already active for at least 1s and MinStab timehas elapsed.
GCB OFF coilThe pulse output for GCB opening. If GCB synchronizing is enabled, the pulse length is 2s, if not, pulselength is 5s.

GCB UV coilGCB undervoltage coil. Output is closed if generator values are within limits and GCB is ready to be closed.It is opened if GCB should be open, and then closed again if generator electric values are in limits. If GCBsynchronizing is enabled, the opening pulse length is 2s, if not, pulse length is 5s.Hint:UV coil automatically opens and OFF coil closes if GCB is closed spontaneously, not from controllers
activity. This state lasts until the GCB status has been deactivated.The only exception is during synchronization state, as an external device is allowed to close the GCB.
GCB statusIndicates breaker state expected by controller (based on gen-set state, controller commands and breakerfeedback). Can be used for external indication of breaker status according to controllers information.
MCB statusIndicates breaker state expected by controller (based on gen-set state, controller commands and breakerfeedback). Can be used for external indication of breaker status according to controllers information.
Neutral CB C/O
Neutral circuit breaker close /open output controls the generator Neutral circuit breaker. It is intended forcontactors provides a continual active signal if NCB should be closed. See also setpoint Neutral cont.

Binary outputs Control loops
AVR up
AVR dnBinary outputs for Volt / PF control by motorized or electronic potentiometer.
Speed up
Speed dnBinary outputs for Synchronizing and Load control. Outputs can be used instead of analog Speed governoroutput for older engine types. Minimum pulse duration is 0,15 sec. Maximum pulse duration is 10,0 sec.
Binary outputs UP nad DOWN of a PID regulator produce pulses, whose length correspond to derivation ofthe analog output (further AOUT) of the same regulator. In other words:
1. If there is no change of the AOUT, no pulses are produced2. If the AOUT is increasing, pulses are generated on the UP output. Pulse length depends on speed of
the increase.3. If the AOUT is decreasing, pulses are generated on the DOWN output. Pulse length depends on
speed of the decrease.4. Long pulses on the same output can merge5. If the calculated pulse in each particular cycle is too short, it is not copied to the output, but is only
buffered. When the buffered pulse exceeds minimal pulse length, pulse is generated to appropriateoutput.
The pulses are generated even if the analog regulator output is already at limit value. As for speed and
voltage regulation, this kind of regulation is good for droop-based systems. At isochronous system, it cancause stability problems, because it is slower.
