• DO 7 "Command: GCB open" (optionally)
•
If the easYgen is intended to be operated in parallel with the mains, the mains voltage
measuring inputs must be connected.
If an external mains decoupling is performed, jumpers between busbar and mains
voltage measuring inputs may be installed.
Engine operation in AUTOMATIC (basic function)
Engine starts, if
• The LogicsManager "86.09 LM: Start req.in AUTO" is fulfilled (TRUE) AND
•
• A shut down alarm is not present AND
•
• The engine is ready for operation
•
With successful start the GCB closure is executed.
• If the voltage of generator and generator busbar is in range, the GCB will be
•
synchronized
If the voltage of generator is in range, and the generator busbar is dead, and no other
GCB is closed, and the MCB is closed the GCB will not be closed but an »operating
range failure« occurs.
Engine stops, if
• The LogicsManager "86.09 LM: Start req.in AUTO" is not fulfilled (FALSE) OR
•
• A shut down alarm occurs
•
Being parallel to mains or to other generator, the generator power will be reduced, before
the GCB will be opened.

Application mode A04 (GCB/MCB)
This application mode (
A04
) may be used for mains parallel operation. In this case, the
easYgen will function as an engine control with generator, mains and engine protection.
The control unit can open and close the GCB and the MCB. The breaker transition modes
“Open Transition”, “Closed Transit.”, “Interchange” and “Parallel” are possible.
The Emergency mode (AMF operation) is supported in this application mode.
