Instrument Panel Switches (1) Starting Aid Switch (SAS) (optional). (2) Engine Control Switch (ECS). (3) Speed Potentiometer (SP). (4) Voltage Adjust Rheostat (VAR). (5) Panel Light Switch(PLS) (optional). (6) Emergency Stop Push Button (ESPB). The engine control switch (ECS) (2) determines the status of the control panel. In the AUTO position, the GSC allows the engine to start whenever the remote initiating contact (IC) is closed. The engine also shuts down after the initiate contacts open. A cooldown period is programmable in order to give a 0 to 30 minute cooldown period before the engine shuts down. The cooldown period is factory set at five minutes. In the MANUAL START position, the engine will be able to start. In the COOLDOWN/STOP position, the fuel solenoid shuts off the engine after the cooldown period. In the OFF/RESET position, the engine shuts down immediately. Also, any fault indicators are reset except the emergency stop. If the red emergency stop push button (ESPB) (6) is pressed, the fuel is shut off. In order to restart the engine, follow these steps. Turn the ESPB (6) 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) (3) controls the engine speed. The speed potentiometer connects to the electrical converter. The electrical converter sends a signal to the PEEC electronic control module. Then, the PEEC electronic control module adjusts the engine speed.The optional panel light switch (PLS) (5) turns the panel lamps ON and OFF. The optional starting aid switch (SAS) (1) is present only on required gensets. Two types of starting aid systems exist. Manual - This type is used for metered shot starting aid systems.Automatic - This type is used for continuous flow starting aid systems.On manual starting aid systems, when the SAS (1) is held in the ON position, the metered shot starting aid system is activated. A specific amount of ether is metered into a holding chamber. When SAS (1) is released, a solenoid allows ether to flow to the engine. The metered shot starting aid system deactivates when any of the following events occurs.
The contacts of the crank termination relay (CTR) open at an engine speed of approximately 400 rpm.
The engine coolant temperature is sufficient to open the start aid temperature switch (SATS).
The SAS (1) is released to the OFF position.
Crank the engine before you activate the metered shot start aid system. Damage to the engine is possible by activating the system when the engine is not turning.
On automatic starting aid systems, the continuous flow starting aid system operates in the automatic mode or the manual mode. When SAS (1) is placed in the AUTO position, the automatic mode is activated. The system automatically injects ether during the crank cycle. When SAS (1) is placed and held in the MAN position (momentary contact), the manual mode is activated. This system allows the operator to control the amount of time that is allowed for the ether to be injected during the crank cycle. The manual mode also allows the operator to inject additional ether after the crank termination. This is usually used on cold running engines which continue to detonate. The automatic mode of the continuous flow starting aid system deactivates when any of the following events occurs.
The contacts of the crank termination relay (CTR) open at an engine speed of approximately 400 rpm. This is only for automatic mode.
The engine coolant temperature is sufficient to open the start aid temperature switch (SATS).
The SAS (1) is returned to the OFF position.
