TANK GP-EXPANSION 2441792 - Caterpillar

programmable spare relay is one of the relays that is located in the relay module that is on the rear of the GSC+. The programmable spare relay outputs respond to a selected trigger condition. The response and the trigger condition are programmable.The GSC+ (setpoint SP15) must be programmed. The programmable spare relay outputs are active or inactive. In an active state, the normally open contacts will close and the normally closed contacts will open. The condition that triggers the programmable spare relay outputs to the active state must be programmed in the GSC+ (setpoint SP16). The possible trigger conditions that can activate the programmable spare relay outputs are listed in System Operation, "Spare Input/Output Programming OP6".See System Operation, "Spare Input/Output Programming OP6" for more information on programming the setpoints for this output. Note: The GSC+ diagnoses a fault in the spare output circuit. See Testing and Adjusting, "CID 448, FMI 12 Programmable Spare Relay Failed-Test" for more information.
