Spare Inputs
The spare inputs are referred to as SP1, SP2, SP3 and SP4. The spare inputs are accessed through the terminal strip. The terminal strip is located within the control panel on the rear wall. The terminations for the spare inputs that are located on the terminal strip are listed below.
SP1 - On certain generators this is marked as "SW1"
SP2 - On certain generators this is marked as "SW2"
SP3 - On certain generators this is marked as "SW3"
SP4 - On certain generators this is marked as "SW4"The active input state, the response that is taken and the time delay for each spare input is programmable. The GSC+ responds to the active state of an input and the response can be delayed. Setpoints SP01 through SP12 are used for the programming of the spare inputs. Table 1 describes each of the setpoints.

Illustration 2 g00409451
Typical Active Low Input Configuration For Spare Input 1 (SP1).The GSC+ must be programmed to accept a HIGH active input state or a LOW active input state. A HIGH active input state is +5 DCV to the voltage of the batteries. A LOW active input state is "B-". When an input is programmed for a HIGH active input state, a HIGH signal at the input creates a spare fault condition. When an input is programmed for a LOW active input state, a LOW signal at the input creates a spare fault condition. When an input is programmed for a LOW active input state, a LOW signal at the input is considered as a spare fault condition. A HIGH signal at the input is considered as a normal condition. Setpoints SP01, SP04, SP07 and SP10 are used to program the active input state of the spare inputs. Table 1 describes each of the setpoints.The GSC+ must be programmed for a response to an active spare fault. Setpoints SP02, SP05, SP08 and SP11 are used for the programming of the response. Table 1 describes the setpoints below.The GSC+ must be programmed for the amount of time to delay the response to a spare fault (active input). Indicators are not activated and codes are not shown until the time delay has elapsed. Also, engine operation is not changed until the time delay has elapsed. Setpoints SP03, SP06, SP09 and SP12 are used for the programming of the time delay. The time delay is selectable from 0 to 250 seconds. Table 1 describes the setpoints.Alarm Mode Sequence Of Operation - If a fault occurs in a spare input that is programmed as an active input, the following steps occur and the fault is programmed as an alarm fault:
The GSC+ waits until the time delay elapses.
The fault alarm indicator FLASHES.
The corresponding code SP1, SP2, SP3 or SP4 is shown on the upper display of the GSC+.
The engine continues to run and the engine is able to start.Shutdown Mode Sequence Of Operation - The following sequence occurs when a fault occurs in a spare input and the fault is programmed as a shutdown fault. The spare input must be programmed to receive an active input.
The GSC+ waits until the time delay elapses.
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 shutdown or the engine is disabled from starting.The fault shutdown indicator remains FLASHING and the spare fault code remains shown until the ECS is turned to OFF/RESET. After turning the ECS to OFF/RESET and correcting the cause of the spare fault, the engine is able to start and the engine is able to run.Note: Spare faults are not logged into the GSC+ fault log.Note: If the customer does not prefer to use the spare inputs, program the spare inputs to receive an active low state. Do not connect any components to the spare input.Spare Indicators
The spare indicators are located on the face of the GSC+ and the spare indicators are referred to as Spare 1, Spare 2, and Spare 3. The spare indicators are programmable. A large selection of trigger conditions is available to activate the spare indicators. Setpoints SP17, SP18 and SP19 are used for the programming of the trigger condition. Table 1 describes all of the setpoints.Spare Output

Typical Active High Configuration For Spare OutputThe spare output responds to a selected trigger condition. The trigger condition should be high or low. The response and the trigger condition are programmable. The spare output is accessed on the terminal strip in the customer connection box on the side of the control panel. The spare output is marked as "SPARE" on the auxiliary terminal strip.The GSC+ must be programmed to accept a high input or a low input for the active state of the spare output. An active low state means that the output is pulled to ground. The output draws approximately 100 mA when the output is in the low state. A high state allows the output to float. When there are no devices that are connected to the spare output, a high input is 5.0 DCV. When the spare output is in the high state, the spare output is floating. The spare output is only capable of driving logic circuits that have a high impedance. A high impedance is defined as an impedance that is greater than 36 000 ohms. When the spare output is in the high state, the spare output will not drive loads that have a low impedance. An example of a load with a low impedance is a relay. Setpoint SP13 is used for the programming of the active state of the spare output. Table 1 describes the setpoints.The GSC+ must be programmed to accept the condition that triggers the spare output to the active state. A large selection of trigger conditions is available to activate the spare output. Setpoint SP14 is used for the programming of the trigger condition. Table 1 describes the setpoints.Note: A
