Encoding of binary inputs’ combinations:
Language index -> given by display setting 1 2 3 4 5 6 7
Lang sel D#3 A 0 1 0 1 0 1 0 1
Lang sel D#3 B 0 0 1 1 0 0 1 1
Lang sel D#3 C 0 0 0 0 1 1 1 1
Hint:
Warning – each language change causes the restart of the respective display (not the whole controller), so
the display’s control panel won’t react until the restart has finished (~ 5s).
Value 0 in the table denotes that the corresponding input is not active or not configured.
If more than 7 languages are present in the controller, it is not possible to force languages with index higher
than 7 using these binary inputs.
The reaction on BI combination change is 1s delayed not to react on transient combinations if a rotary
selector switch is used.
Binary inputs – Status information
GCB feedback
Generator Circuit Breaker positive feedback input (closed if GCB is closed). This is a primary source for the
controller about the status of the GCB.
GCB fdb neg
Generator Circuit Breaker negative feedback input (closed if GCB is open). Additional signal, can be used if
both positive and negative feedback signals are available from the breaker.
Hint:
If both feedbacks are used and there is a mismatch between these signals, longer than 500 ms, a GCB fail
alarm is activated.
MCB feedback
Mains Circuit Breaker positive feedback input (closed if MCB is closed). This is a primary source for the
controller about the status of the MCB.
Hint:
The controller decides based on this signal whether the gen-set is running in mains parallel or island
operation.
MCB fdb neg
Mains Circuit Breaker negative feedback input (closed if MCB is open). Additional signal, can be used if both
positive and negative feedback signals are available from the breaker.
Hint:
If both feedbacks are used and there is a mismatch between these signals, longer than 500 ms, a MCB fail
alarm is activated.
NeutralCB fdb
Use this input to detect, whether the Neutral circuit breaker is open or closed. See also setpoint Process
control: #Neutral cont. and binary output Neutral CB C/O.
Binary outputs – Breaker control
GCB close/open
The output controls the generator circuit breaker. It is intended for contactors – provides a continual active
signal if GCB should be closed.
