14.2.1.4 Binary output: MGCB OFF Coil
This output is intended for opening of the MGCB using OFF coil if a circuit
breaker is used as MGCB. The output provides 2 sec pulse when the MGCB
has to open. If synchronizing is disabled with the particular breaker, the pulse
length is extended to 5sec. See timing diagram of all available breaker
control outputs in the description of the MCB close/open output.
There are also other outputs availabe for MGCB control:
MGCB close/open
MGCB ON coil
MGCB UV coil
14.2.1.5 Binary output: MGCB UV Coil
This output is intended for opening of the MGCB using an undervoltage coil if a
circuit breaker is used as MGCB.
The output is closed while bus values are within limits. MGCB closing
command is blocked for 1 sec after the UV coil has been closed to allow
the breaker mechanical system getting ready for closing.
The output is opened for 2 sec when the MGCB has to open. If
synchronizing is disabled with the particular breaker, the length of the
inverse pulse is extended to 5sec.
