Relay Output Functions
Discrete Output #1—Mains Utility Breaker Close
With the relay de-energized, this output has Normally Open (NO), terminals 5
and 6, and Normally Closed (NC), terminals 6 and 7, contacts to select from.
The “Mains (utility) Breaker Close” relay output is utilized by the EGCP-2 to
command the Mains (utility) Breaker to close. This output is configured for use
with a BREAKER or a CONTACTOR in the Configuration menu under “CKT
Breaker Control”. Every EGCP-2 that has the capability of being a MASTER unit
must have this relay wired into the Mains (utility) Breaker close circuitry.
Breaker
When in the Breaker configuration, the EGCP-2 will ENERGIZE (momentary) to
close the Mains (utility) Breaker. The ENERGIZE time is determined by the “CB
Hold Time” in the Synchronizer menu. Discrete Output #9 is used to open the
mains breaker.
