TRICONEX FTA-544 17-550544-001B module

Contactor The “Generator Breaker Close” output is used to close and open the Generators Contactor. The “Generator Breaker Trip”, discrete output #10, is NOT used in the Contactor mode. The EGCP-2 will DE-ENERGIZE (continuously) to open the Generators Contactor and ENERGIZE (continuously) to close the Generators Contactor. This is reverse logic from the Mains Contactor Close, discrete output # 1.

Discrete Output #3—Engine Preglow

 The “Engine Preglow” relay output utilizes a set of normally open (NO) contacts on terminals 11 and 12. The “Engine Preglow” relay output is utilized by the EGCP-2 to turn on a diesel engine’s glow plugs, if so equipped. This relay will energize for a programmed length of time, based on the “Preglow Time” setting, before an engine crank command is given. Discrete Output #4—Fuel Solenoid The “Fuel Solenoid” relay output utilizes a set of Normally Open (NO) contacts on terminals 13 and 14 to energize the engine’s fuel solenoid. The Configurations menu, “Start Sequencing” setting of Enabled or Disabled, determines the EGCP-2’s start process.

Start Sequencing—Enabled 

This relay ENERGIZES at the same time an Engine Crank command is initiated, and stays on until a shutdown command is received. The EGCP-2 must have a Magnetic Pickup (MPU) signal to operate in this condition. Start Sequencing—Disabled The EGCP-2 will ENERGIZE (continuously) the Fuel Solenoid relay when a start command is given. It will De-energize when a shutdown command is received. The fuel solenoids output will function as a Run/Stop relay. There is no “Engine Preglow” or “Engine Crank” command in this mode. The Disabled mode allows the EGCP-2 to operate without a Magnetic Pickup (MPU) signal.
