The output can be used for indication of the MCB position.
Binary output: Bank params OK
Related FW 3.0
Description This output indicates that the bank actually provides proper voltage and
frequency. The output is closed while the bank of gen-sets is running (regardless
of whether BCB is closed or not) and
all bank electrical parameters are in limits.
Binary output: Bus Params OK
Related FW 3.0
Description This output indicates that the bus is healthy. The output is closed while all bus
electrical parameters are in limits.
Binary output: kWh pulse
Related FW 3.0
Description This output generates 100ms pulse always when the internal kWh counter
incremented.
Binary output: In synchronism
Related FW 3.0
Description This output is closed during synchronization when all synchro conditions have
been fulfilled. The output is opened either when:
•
the synchro conditions are lost or
•
the corresponding breaker has been closed or
•
the sychronizing was interrupted or timed out.
Synchro conditions are following:
•
Phase shift between generator and mains (bus) voltage must be within
range of ±
Phase window for period longer than Dwell time .
•
Voltage difference between generator and mains (bus) voltage (in all
phases) must be lower or equal to
Voltage window for period longer than
Dwell time .
The output is intended for manual synchronization. Automatic closing of GCB
must be disabled for this case. Use the input GCB disable .
