SP Fault Codes
SP 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.
