Information:
OP6 is the option for programming of the spare inputs. OP6 is the option for programming the spare output. These spare inputs and spare outputs are provided in order to satisfy the needs of the customer.Spare Inputs
The spare inputs are referred to as SP1, SP2, and SP3. The spare inputs are accessed on the auxiliary terminal strip (AUX) within the control panel on the left wall. The terminations at the auxiliary terminal strip for the spare inputs are marked. SP1 is marked as "SW1". SP2 is marked as "SW2". SP3 is marked as "SW3".The following tasks for each spare input are programmable: active input state, response taken and time delay. The GSC responds to the active state of an input, although the response can be delayed. Setpoints SP01 through SP06 and SP08 through SP10 are used for programming the spare inputs. Each of the setpoints is described in the following topics.
Illustration 1 g00308511
Typical Active High Input Configuration For Spare Input 1 (SP1)
Illustration 2 g00307940
Typical Active Low Input Configuration For Spare Input 1 (SP1)The active input state must be programmed into the GSC. A high state is 5 DCV to B+. A low state is B-. When an input is programmed for an active high state a high state at the input is a spare fault. A low state at the input is a normal condition. When an input is programmed for an active low state, a low state at the input is a spare fault. A high state at the input is a normal condition. Setpoints SP01, SP03 and SP05 are used for the programming of the active input state of the spare inputs.Note: If an input is left floating, then the internal circuitry of the GSC pulls the input high. The GSC will respond accordingly.The GSC response to an active spare fault must be programmed. One response option treats the condition as a shutdown fault. The other response option treats the condition as an alarm fault. Setpoints SP02, SP04, and SP06 are used for programming the response.Note: Spare faults that are programmed to shutdown are ignored by the GSC when engine speed is less than crank termination speed. The GSC must be programmed for the amount of time to delay the response to a spare fault (active input). After a spare fault occurs, the GSC does not respond until the time delay has elapsed. Indicators are not activated. Codes are not shown. The operation of the engine has not changed. Setpoints SP08, SP09, and SP10 are used for programming the time delay. The time delay is selectable from 0 to 250 seconds.SP01 Spare Input 1 Active State
