System Schematic For Spare Fault Inputs
A spare fault informs the operator of an undesirable condition (fault) that exists. The spare inputs are programmed into the GSC to meet the requirements of the customer or application. An active spare input causes an alarm fault or a shutdown fault. For programming of the spare inputs, see Systems Operation, "Spare Input/Output Programming OP6". The programmer (customer, operator, or service personnel) is responsible for noting the actual conditions that cause a SP fault code. The GSC does not diagnose the spare inputs and spare faults are not recorded in the fault log.The GSC treats an active input state as a fault. The active state is programmable on the GSC to be either a high or a low (factory default) voltage level. A high level is within the range of +5 DCV to the positive battery. If the input is left floating (for example an open switch), the GSC pulls the input voltage up to 10.5 DCV and the input is treated as high level. A low level on the input is B− (ground).When a spare fault occurs (active), the GSC determines the type of fault (alarm or shutdown). The GSC also FLASHES the corresponding fault alarm indicator or fault shutdown indicator. For a shutdown type of fault, the SP fault code is immediately shown on the upper display. For an alarm type of fault, the alarm code key is pressed first. Then the SP fault code is shown on the upper display. After a spare fault is corrected or is not present, the SP fault code is no longer shown on the upper display.

(1) See Spare Input/Output Programming OP6 within the topic Service Mode in the Systems Operation section.SP fault codes are associated with the spare inputs. The SP fault code that is shown on the upper display, identifies the spare input that caused the alarm fault or shutdown fault. The spare inputs are accessed on the terminal strip within the control panel on the rear wall.When a SP fault code is showing on the upper display, check the programming notes in order to determine the cause.Note: On generators equipped with the optional reverse power relay, the relay is always connected to the spare fault 1 (SP1) input of the GSC. An SP1 fault code is shown when the reverse power relay has opened.Troubleshooting Procedure
In order to troubleshoot spare faults, use the following general procedure.
Check for obvious causes which are related to the device that is responsible for the spare fault.
Verify that the programming of the spare fault (alarm or shutdown) is appropriate for the application.
Check the function of the responsible device. Reset the fault by turning the engine control switch (ECS) to the OFF/RESET position. Verify that the fault is still present.
Disconnect the responsible device from the spare fault input and verify if the fault still exists.
Check the wiring to the corresponding spare fault input for an unwanted short to either battery negative ("B-") or battery positive ("B+").
