C.B. Hold Time 

• Time in seconds that Breaker/Contactor Close output is held after breaker close command is issued. 

• The Breaker/Contactor Close command is removed when the C.B. Hold Time is done, if a Generator Breaker Aux feedback is received, or if the synchronization conditions fall outside the voltage and/ or speed specifications. Close Attempts 

• Number of Close Attempts allowed while synchronizing. 

• Close attempt incremented if breaker does not send back continuous CB Aux signal to EGCP-2. Reclose Delay 

• Time in seconds before EGCP-2 control attempts resynchronization after failed closure attempt.

Synchronizer Time Out 

• Sets time allowed for synchronization in seconds. 

• Begins timing when synchronizer activates. 

• Active for all gen and mains breaker open and close commands from EGCP-2 control. 

• A setting of zero (0) seconds disables synch. time-out—infinite synch time allowed. Synch Time-out Alarm 

• Sets alarm mode if synch time-out is exceeded. Shutdown actions are not allowed.

Dead Bus Closure

 • Enables/Disables Dead Bus Closing Feature in a multiple unit application. 

• Dead Bus Closing is always active when configured for single unit operation. 

• Unit must be within voltage and frequency high/low limits to be considered for dead bus closure.

 • Dead Bus Closure uses Token Passing Scheme to assure that only one unit in a networked system will close onto the dead bus at any given time. 

• Multiple unit systems must be in the AUTO mode to allow dead bus closing between networked units.
