Relation between GCB and MCB
Conditions: AUTO Mode, Mains =off, MCB = opened, GCB = closed, gen-set loaded.
Mains returns: GCB opens ( MainsReturnDel ), MCB closes ( Transfer Del )
GCB opened
MCB closed
Transfer Del
Relation between GCB and MCB (Test mode)
Situation 1 : Mains =OK, MCB = closed, GCB =opened, RPM=0.
Change mode to TEST: gen-set starts, GCB =opened.
Mains cut: MCB opens, GCB closes (
Transfer Del )
Situation 2 : ReturnFromTEST =MANUAL, Mains =OK, MCB is closed, gen-set is running.
Press MCB on/off -> MCB opens, GCB closes ( Transfer Del ), gen-set is running loaded.
MCB opened
GCB closed

Source evaluation
Source evaluation is same for generator and mains. Setpoints and binary inputs connected with
source evaluation are:

GenProtect setpoint (for generator)

MainsProtect setpoint (for generator)

GenReadyToLoad binary input (for mains)

MainsHealthy binary input (for mains)
State of source can be evaluated in these ways:

Binary input only

Measured values only

Binary input and measured values
Binary input only
In this case the binary input GenReadyToLoad or MainsHealthy has to be configured. After
configuration of binary input, related setpoint GenProtect or MainsProtect should be adjust to
DISABLED. After that the source will be evaluated only from binary inputs.
Measured values only
In this case the binary input GenReadyToLoad or MainsHealthy can´t be configured. Related setpoint
GenProtect or MainsProtect is adjust to valeu ENABLED and its value can´t be changed. Source is
evaluated only from measured values (voltage and frequency).
Binary input and measured values
In this case the binary input GenReadyToLoad or MainsHealthy has to be configured After
configuration of binary input, related setpoint GenProtect or MainsProtect should be adjust to
ENABLED. After that the source will be evaluated from both sources. To evaluate that source is health
the values of voltage and frequency have to be in limits and also related binary input has to be in
logical one.
