Shut down (SD)
When the shut-down alarm comes up, InteliLite opens outputs GCB CLOSE/OPEN, FUEL
SOLENOID, STARTER and PRESTART to stop the engine immediately. Alarm outputs and common
shutdown output are closed. Active or not reset protection disables start.
Possible shut-down alarms:
Mains failure (MF)
Mains failure detection depends on
Auto mains failure
setpoints (levels and delays) adjusting. When
the mains failure comes up, mains circuit breaker is opened.
Possible mains failure reasons:
Hint:
Mains failure is not written to alarm list!

Voltage phase sequence detection
InteliLite controller detects phase sequence on both generator and mains/bus voltage terminals. This
protections are important after controller installation to avoid wrong voltage phases phase connection.
Following alarms can be detected:
Wrong phase sequence
There is fix defined phase sequence in InteliLite controller L1, L2, L3. When the phases are connected
in different order (e.g. L1,L3,L2 or L2,L1,L3) following alarms are detected:
Gen CCW Rot = wrong generator phase sequence
Mains CCW Rot = wrong mains phase sequence
