14.2.1.68 Binary output: ReverseSynchro
The output is closed during reverse synchronizing (synchronizing of loaded
gen-set group back to the mains) and opens when the output MCB status is
activated (= MCB was closed).
NOTE:
The output can be used for external synchronizing module control.
14.2.1.69 Binary output: In synchronism
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:
Slip frequency is lower than 0.25 Hz
Phase shift between mains and bus (BusLeft and BusRight - in BTB
application) voltage must be within range of ±Phase window for
period longer than Dwell time.
Voltage difference between mains and bus (BusLeft and BusRight -
in BTB application) 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
MCB/MGCB must be disabled for this case. Use the input MGCB disable or
MCB disable.
14.2.1.70 Binary output: Ready for Load
MGCB application only!
The output closes when the gen-set group is running (Sys start/stop is active)
and output SystReady is active (i.e. sufficient number of gen-sets in Power
management is available).
The MGCB may be already closed or is available to closing.
