CIRCUIT BREAKER GP 3932367 - Caterpillar

fault codes are associated with the spare inputs. SP fault codes are either alarm faults or shutdown faults. The four spare inputs and a spare output are provided in order to meet the needs of the customer. The spare inputs are programmable to active state, severity, and delay time. See System Operation, "Spare Input/Output Programming OP6". The spare inputs and the corresponding SP fault codes are referred to as SP1, SP2, SP3, and SP4.Alarm Mode Sequence Of Operation - The following procedure happens when a fault occurs in a spare input (the active input ) and the fault is programmed as an alarm fault.
The GSC+ waits for the time delay.
The fault alarm indicator FLASHES.
When the alarm code key is pressed, the corresponding code SP1, SP2, SP3, or SP4 is shown on the upper display.
The engine continues to run or the engine is able to start.Shutdown Mode Sequence Of Operation - The following sequence happens when a fault occurs in a spare input and the fault is programmed as a shutdown fault.
The GSC+ waits for the time delay.
The fault shutdown indicator FLASHES.
The corresponding code SP1, SP2, SP3, or SP4 is immediately SHOWN on the upper display of the GSC+.
The engine is shut down or the engine is disabled from starting.Note: Spare faults are not logged into the GSC+.Note: Spare faults that are programmed to shutdown are ignored by the GSC+ when the engine speed is less than crank terminate speed.
