Application Mode {1oc}
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
This application mode may be used in applications, where only the GCB is operated by the easYgen. If it is used
for isolated or mains parallel operations, mains decoupling should be performed by the GCB or an external provi-
sion. The easYgen will function as an engine control with generator and engine protection. The control unit can
open and close the GCB.
Figure 2-3: Application mode {1oc}
The easYgen requires in all application modes the feedback reply from the circuit breakers. These replies are
used to define, whether it controls frequency, shares the load with other gensets, or performs active load control.
The following feedback signals and commands are used in this application mode and fixed to the respective dis-
crete inputs and outputs:
•
DI 7 "Reply MCB" (mains parallel; normally closed (break) contact)
•
DI 8 "Reply GCB" (normally closed (break) contact)
•
DO 6 "Command: GCB close"
•
DO 7 "Command: GCB open"
NOTE
If the easYgen is intended to be operated in parallel with the mains, the mains voltage measuring in-
puts must be connected.
