GCB UV COIL OUTPUT TIMING
There are also other outputs availabe for GCB control:
GCB close/open
GCB ON coil
GCB OFF coil
Binary output: MCB Close/Open
This output is intended for control of the MCB if a contactor is used as MCB. The
output provides continuous signal while the MCB has to be closed. See timing
diagram of all available breaker control outputs in the description of the GCB
close/open output.
NOTE:
Use invert function when configuring the output in GenConfig to obtain inverted
function of the output, i.e. output is closed while the MCB has to be open.
There are also other outputs availabe for MCB control:
MCB ON coil
MCB OFF coil
MCB UV coil
Binary output: MCB ON Coil
This output is intended for closing of the MCB using ON coil if a circuit breaker is
used as MCB. The output provides 2 sec pulse when the MCB has to close. 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
