BOC IDMT
A+H
Indicates current IDMT protection activation. Current IDMT
protection is inverse definite minimum time protection
which is based on the generator current. Protection
reaction time depends on overcurrent value. High
overcurrent means short reaction time whereas low
overcurrent means longer reaction time. Protection is
based on setpoints

MPR Imains IDMT
A+H
Indicates current IDMT protection activation. Current IDMT
protection is inverse definite minimum time protection
which is based on the mains current. Protection reaction
time depends on overcurrent value. High overcurrent
means short reaction time whereas low overcurrent means
longer reaction time.
This protection is active if the

BOR IbusL IDMT
A+H
Indicates current IDMT protection activation. Current IDMT
protection is inverse definite minimum time protection
which is based on the left bus current. Protection reaction
time depends on overcurrent value. High overcurrent
means short reaction time whereas low overcurrent means
longer reaction time.

BOC Overload
A+H
Indicates overload IDMT protection activation. Overload
IDMT protection is inverse definite minimum time
protection which is based on the generator power.
Protection reaction time depends on generator power
value. High generator overload means short reaction time
whereas low generator overload means longer reaction
time. Protection is based on setpoints
