Breaker Logic "INTERCHANGE" [GCP-32]
Mains interchange (import/export) real power control is enabled via configuration of the parameter (Para-
m
eter 126) to "INTERCHANGE".
NOTE
For this breaker logic to function correctly, the mains power measurement must be connected proper-
ly. The power measurement must also be assigned the properly process identifier (C, I, or E).
In the event of an add-on request, a change is made from mains to generator supply. The following occurs:
• The GCB is synchronized and closed
• The generator assumes load until the mains interchange (import/export) real power is "zero"
• The MCB is opened
When a shed-off request has been issued, a change is made from generator to mains supply. The following oc-
curs:
• The MCB is synchronized and closed
• The generator sheds load until real power is "zero"
• The GCB is opened
Breaker Logic "CLOSED TRANSIT." [GCP-32]
Closed transition (make-before-break/overlap synchronization) is enabled via configuration of the parameter
(Parameter 126) to "CLOSED TRANSIT.".
NOTE
The circuit breakers are opened irrespectively of the power.
In the event of an engine request, a change is made from mains to generator supply. The following occurs:
• The GCB is synchronized and closed
• The MCB is opened and the generator assumes all loads
After the engine shed-off request has been issued, a change is made from generator to mains supply. The follow-
ing occurs:
• The MCB is synchronized and closed
• The GCB is opened and the mains assume all loads
NOTE
The maximum time between reply CB and CB open command is 500 ms.
