The EGCP-2 monitors the A phase of the generator and compares this with either the A phase of the Bus PT input, or the A phase of the Mains PT input. The Bus PT input is switched through DO7 (local bus connect). The Bus PT is always monitored whenever the EGCP-2 is synchronizing, or dead bus closing across the generator breaker. Bus PT sensing is a momentary condition as the EGCP-2 will always return to sense the Mains PT input by switching to DO8 (Mains Disconnect) whenever generator synchronization is complete. Switching to the Mains PT allows the EGCP-2 to monitor for a loss of mains condition when operating on a generator that is not synchronizing across its generator breaker.

Check mode allows normal synchronizing
and voltage matching, but does not issue a breaker closure signal. Permissive mode enables the synch-check function for proper synchronization, but synchronizer operation does not affect the engine's speed or generator voltage. If phase, frequency, and voltage are within proper limits for the specified dwell time, the synchronizer issues the breaker closure command.
