The output can be used for indication of the MCB position.
Binary output: Gen params OK
Related FW 3.2
Description This output indicates that the generator actually provides proper voltage and
frequency. The output is closed while the gen-set is running (regardless of
whether GCB is closed or not) and all generator electrical parameters are in
limits.
N
OTE
This output combined with a PLC block Delay can be used for switching on/off of
some auxiliary devices (e.g. cooling pump), that are supplied directly from
generator (before GCB). The delay is reccommended to allow the generator
getting stable and avoid unnecessary switching the auxiliary device on and off just
after start.
Binary output: MainsParams OK
Related FW 3.2
Description This output indicates that the mains is healthy. The output is closed while all
mains electrical parameters are in limits.
Binary output: kWh pulse
Related FW 3.2
Description This output generates 100ms pulse always when the internal kWh counter
incremented.
Binary output: In synchronism
Related FW 3.2
Description This output is closed during synchronization when all synchro conditions have
been fulfilled. The output is opened either when:
Synchro conditions are following:

:

the synchro conditions are lost or

the corresponding breaker has been closed or

the sychronizing was interrupted or timed out.

Phase shift between generator and mains (bus) voltage must be within
range of ±Phase window

Voltage difference between generator and mains (bus) voltage (in all
phases) must be lower or equal to
