(1) Pump Stop Switch (not used on 3500 generator sets) (2) Starting Aid Switch (SAS) (optional) (3) Pump Run Switch (not used on 3500 generator sets) (4) Voltage Adjust Rheostat (VAR) (5) Panel Light Switch (PLS) (6) Speed Potentiometer (SP) (optional) or Governor Switch (GS) (optional) (7) Emergency Stop Push Button (ESPB) (8) Engine Control Switch (ESC) (9) Parallel Mode Switch MANUAL (PERMISSIVE) Position (10) Parallel Mode Switch OFF Position (11) Parallel Mode Switch (Parallel Panels only) (12) Parallel Mode Switch AUTO Position (13) Parallel Mode Switch SEMI-AUTO Position (14) Open Breaker Switch (Paralleling Panels only) (15) Close Breaker Switch (Paralleling Panels only)The Engine Control Switch (ECS) (8) determines the status of the control panel. In the AUTO position, the GSC+ allows the operator to remotely control the generator set with a Customer Communication Module (CCM). Also, the GSC+ allows the operator to remotely monitor the generator set with a CCM. See Systems Operation, "Customer Communication Module". The GSC+ allows the engine to start whenever the remote start/stop initiate contact (IC) is closed. After the remote start/stop initiate contact (IC) opens, the engine will shut down. A cooldown time delay is programmable from 0 to 30 minutes before the engine shuts down. The setpoint is P019. The cooldown time delay has a factory setting of five minutes. The engine starts and the engine runs while the ECS is in the MANUAL START (6 o'clock) position. In the COOLDOWN/STOP (9 o'clock) position, the fuel control solenoid shuts the engine down after cooldown. In the OFF/RESET position (12 o'clock), the engine shuts down immediately. The fault indicators are reset. The emergency stop light is not reset while the ESPB is depressed.If the red emergency stop push button (ESPB) (7) is pressed, the fuel is shut off. The operator must turn the ESPB (7) clockwise until the ESPB releases in order to restart the engine. Next turn the ECS to OFF/RESET and then turn the ECS to the MANUAL START.The Voltage adjust rheostat (VAR) (4) connects to the voltage regulator and the VAR is used to adjust generator voltage to the desired level. The VAR is used in place of the voltage level rheostat that is located on the generator regulator assembly.The optional speed adjust potentiometer (SP) (6) is used to raise the engine speed. Also, the optional speed adjust potentiometer (SP) is used to lower the engine speed when the generator is using an electronic governor. An optional governor is mounted in this location, if a governor that is equipped with a speed adjust motor is used.The panel light switch (PLS) (5) turns ON the panel lamps and turns OFF the panel lamps.The optional pump run switch (3) is used in conjunction with the automatic fuel transfer system if the generator set is equipped. The pump run switch is not used with the 3500 generator sets. The AC fuel transfer pump will fill the day tank of the generator set when the operator pushes the pump run switch. The
