Page 7: Operating Mode
DGC-7R Digital Genset Controller DG Freq This LED blinks when the engine is stopped on frequency fault. DG Vol This LED blinks when the engine is stopped on voltage fault. Over Speed This LED blinks when the engine is stopped on over speed fault. V-Belt This LED blinks when the engine is stopped on V-Belt fault. -
Page 8: Off Mode
DGC-7R Digital Genset Controller switch shall not operate if GCB contact is closed, to provide protection to generator. Once the generator is started the load can be switched to generator by pressing “GCB” switch or to mains by pressing MCB switch. At any given time, either of GCB or MCB can be operational. Attempt to switch on GCB while MCB is on will be ignored and vice versa. -
