– BI: RunIndication 1 and 2 and 3 are not active and
– Generator voltage < 15 V (in all phases) and
– Generator frequency = 0 Hz
If all these conditions are fulfilled, additional 2 delays are used to confirm
“still engine” state.
Alarm: Bus power loss sensing
The “Bus Measure Error” is detected in MINT application when the voltage
on the controller’s bus terminals is out of limits 20 after:
a) GCB (own) was closed in MAN or AUT mode
b) MCB (feedback) was closed in AUT mode
c) Any other GCB in power management group (on CAN bus)
was closed.
The alarm is activated after 20 s. However, the GCB (own) closing is
blocked immediately for safety reasons.
This protection can avoid e.g. potential direct closing of GCB while the
controller’s bus conductors are unintentionally unplugged from the terminals.
Neutral Circuit Breaker (NCB) Failure was detected.
a) Wrong connection between breaker feedback signals and controller
binary input.
b) Wrong breaker signal logic or breaker signal feedback signal logic.
This alarm occurs when the fuel level value measured at relevant AI (Fuel
Level) drops faster than is the limit adjusted by setpoint MaxFuelDrop.
