Mode and function description
There are four gen-set operation modes: OFF - MAN – AUT – TEST in SPtM application. There are
three gen-set operation modes: OFF - MAN – AUT in SPI, COX and MINT application.
To select the mode use MODE→ or ←MODE.
OFF mode
• No start of the gen-set is possible. Outputs STARTER, GCB CLOSE/OPEN and FUEL
SOLENOID are not energized.
• No reaction if buttons START,STOP,GCB ON/OFF are pressed.
• MCB behavior depends on AMF settings: MCB opens on setpoint:
MAINSFAIL: When power-cut comes, MCB opens. After Mains returns, MCB closes with MCB
close del.
GEN RUNNING:When power-cut comes, MCB stays closed until the gen-set starts and
produces voltage within limits.
MAN mode
1) To start the gen-set press START.
2) When the generator voltage is within limits (adjusted in the setpoints group Generator
protections) GCB green LED on the front panel lights.
3) Press GCB ON/OFF to close the GCB. If the generator voltage is out of the limits, controller does
not respond to the GCB ON/OFF .
a) If controller detects dead bus, immediately closes GCB OPEN/CLOSE output.
b) If controller detects voltage on the bus, starts synchronizing.
4) To stop the engine press STOP
a) controller unloads the gen-set, opens GCB CLOSE/OPEN. Unloading is active only when
binary input MCB feedback is closed or other gen-set is connected to bus. In other case GCB
CLOSE/OPEN opens immediately.
b) Gen-set is cooled down and stopped.
Hint:
Controller does not respond to external signals and/or conditions. The gen-set is fully in manual
control; there is no automatic way to stop it (except protections). The gen-set stays running until STOP
button is pressed.
Controller does not take place in Power management in MINT application
AUT mode
Gen-set is controlled based on external signals (Rem start/stop, Sys start/stop) or conditions (AMF,
Peak shaving, Power management system, …).
Hint:
Engine does not stop, if other condition for automatic starts is active.
Example: If peak stop condition occurs, but REMOTE START/STOP is active, engine stays running.
Controller does not respond to GCB ON/OFF , MCB ON/OFF, STOP, START buttons and
corresponding remote InteliMonitor or Modbus commands.
Set Basic setting: FltRes GoToMAN = ENABLED to avoid automatic engine start when pressing
FAULT RESET after Shut down or Slow stop alarm.
Engine can start automatically without warning when pressing FAULT RESET after shut down alarm.
