AUT mode
No AMF function in SPI application.
Remote start/stop
Gen-set starts automatically, when binary input REM START/STOP is closed and stops when the input is
opened. If there is no mains present or the MCB feedback is not closed, the gen-set won’t start.
• When Mains is within limits and MCB feedback is closed the controller starts RPM matching and
closes GCB when all matching conditions are met (see in MAN mode). Gen-set remains running in
parallel.
• When Mains failure is recognized during parallel operation - controller opens GCB and if this state
continues for 1 minute, it will stop the engine.
• After mains recovers and MCB feedback is closed again (MCB is controlled externally), the controller
starts RPM matching and closes GCB when all matching conditions are met. Gen-set remains
running in parallel.
Peak shaving
Gen-set can start and stop automatically according to consumption from the mains (object). IE measurement
must not be set to NONE and ProcessControl:PeakAutS/S del must be greater than 0.
If Mains import value exceeds for more than ProcessControl:PeakAutS/S del
ProcessControl:PeakLevelStart, engine starts automatically.
If Load consumption (Mains import + Gen-set power) drops for more than ProcessControl:PeakAutS/S del
below ProcessControl:PeakLevelStop, engine stops.
Hint:
Engine does not stop, if some other condition for automatic start is active.
Example: If peak stop condition occurs, but REMOTE START/STOP is active, engine stays running.
The controller does not respond to GCB ON/OFF, STOP, START buttons and corresponding remote
commands of InteliMonitor or Modbus communication.
Set Basic setting: FltRes GoToMAN = ENABLED to avoid automatic engine start when pressing FAULT
RESET after any 2
nd
level alarm (Shutdown, Slow stop, Breaker Open&Cooldown).

Mode Function Setpoints
Baseload Gen-set power is constant - set by
Baseload setpoint.
ProcessControl: Load ctrl PtM=BASELOAD;
Base load
ANEXT Baseload Gen-set power is set via Analog input. ProcessControl: Load ctrl ANEXT Baseload;
Analog input: LdCtrlAnextBld
Import / Export Import/Export value is constant – I/E
power is measured by controller.
ProcessControl: Load ctrl PtM=IM/EX;
Import load; I/E Pm-meas = IM3 CT INPUT
ANEXT
Import / Export
Import/Export value is constant – I/E
power is measured via Analog input.
ProcessControl: Load ctrl PtM=IM/EX;
Import load; I/E Pm-meas = ANALOG INPUT
Analog input: LdCtrl:I/E-Pm
Warming The controller limits gen-set power for
requested time or until the water
temperature reach the requested value.
After warming the gen-set goes to the
requested (e.g. Baseload) power.
Engine params: Warming load;
Warming temp; Max warm time
Peak shaving Automatic gen-set start/stop based on
object (load) consumption.
ProcessControl: PeakLevelStart;
PeakLevelStop; PeakAutS/S del
Export limit Limits export to the mains in the
Baseload mode.
ProcessControl: Export limit = ENABLE
