Instrument Panel Switches (1) Speed Potentiometer (SP). (2) Panel Light Switch (PLS). (3) Engine Control Switch (ECS). (4) Voltage Adjust Rheostat (VAR). (5) Emergency Stop Push Button (ESPB). The engine control switch (ECS) (3) determines the status of the control panel. In the AUTO position, the GSC allows the operator to remotely control the generator set.. The GSC enables the engine in order to start whenever the remote contact (IC) is closed. The engine also shuts down after the initiate contacts open. A cooldown period is programmable using (setpoint P19). The setpoint is programmable in order to provide a 0 to 30 minute cooldown period. The cooldown period is factory set at five minutes. In the MANUAL START position (6 o'clock), the engine starts and runs as long as the ECS is in this position. In the COOLDOWN/STOP position (9 o'clock), the fuel solenoid shuts down the engine after the cooldown period. In the OFF/RESET position (12 o'clock), the engine shuts down immediately and any fault indicators are reset except the emergency stop. If the red emergency stop push button (ESPB) (5) is pressed, the fuel is shut off. In order to restart the engine, follow these steps: Turn the ESPB (5) clockwise until the push button releases. Turn the ECS to OFF/RESET and then turn the ECS to MANUAL START.The voltage adjust rheostat (VAR) (4) is used to adjust the generator voltage to the desired level.The speed adjust potentiometer (SP) controls the engine speed.The panel light switch (PLS) (2) turns the panel lamps ON and OFF.
