procedures. Users can control the loading transfer of ATS via pressing button to switch on or off.
Breaker Close Operation: During genset normal running, press
have reached on-load requirements.
1)
When single genset is running, generator closing relay outputs;
2)
When gensets are running in parallel,
a) If bus has no voltage signal, then the controller will issue a close status signal to other gensets
waiting for combination in parallel. Then generator close relay will output, avoiding to close the
breaker at the same time;
b) If bus has voltage or other gensets are already closed, the controller will adjust speed and
voltage through GOV and AVR to synchronize the gensets to the bus; when synchronization
requirements have been achieved, breaker close signal will be initiated and the genset will be
paralleled with the bus. Once they are paralleled, the controller will control the generator to
gradually accelerate and share load with other paralleled gensets.
Breaker Open Operation: Press the
1) When single genset is running, the controller sends open breaker signal.
2)
When gensets are running in parallel, the controller shall transfer the load to other gensets and
then issue open signal.

AUTOMATIC CONTROL PROCEDURES
When controller is in Auto mode, the switch control procedure is automatic control procedure.
