If GCB output used GCB opens automatically
3
The start-up sequence can be interrupted in any time by comming stop request
4
Fuel solenoid is switched on with time advance of 1s fixed before starter motor is switched on.
Hint:
Threshold level for D+ input is 80% supply voltage, activation delay is 1s (to override short firings
during cranking – for example in cold conditions).
AUT Mode
The controller does not respond to buttons START, STOP, MCB ON/OFF, GCB ON/OFF. Engine
start/stop request is evaluated form Mains failure/return.
