Additional Conditions
The functions described above for terminal 6 are dependent upon the conditions listed in Table 4-3 in conjunction
with the states of the discrete inputs. The desired function must also be enabled when configuring the control unit.
Condition
A
Synchronization
Generator circuit breaker

N
The synchronization will be aborted after monitoring time expires
B
Dead bus start
Generator circuit breaker
-
Parameter "Dead bus start GCB" is configured "ON"
-
Synchronization reference voltage must be less than 5% of the rated voltage
-
Generator voltage and frequency must be within the configured limits of the dead
bus start
