When to use GCB ON/OFF button?
The button is disabled in AUT mode.
In MAN and TEST modes it is enabled, but before closing of the circuit beaker, generator voltage and
frequency must be within limits. The controller has internal protection to avoid the breaker closure
without synchronizing.
The controller recognizes automatically:
•
if there is mains / bus voltage and the gen-set shall be synchronized before closing the GCB
•
or if there is no voltage on the bus and the GCB can be closed without synchronizing.
When to use MCB ON/OFF button?
The button is disabled in AUT mode.
Use this button in MAN or TEST mode to close or open the MCB.
Be careful while doing this,
because you can disconnect the load from the mains!!!
