Emergency Stop Push Button (ESPB)
The emergency stop push button (ESPB) (9) is used to shut down the engine during an emergency situation. When the ESPB is pressed, the fuel to the engine is shut off. If equipped, the optional air shutoff solenoid (ASOS) is activated. When the ESPB is pressed, the ESPB locks into the PRESSED position. In order to restart the engine, the ESPB must be returned to RELEASED position. To return the ESPB to the RELEASED position, rotate the ESPB in the clockwise direction or pull the ESPB until the ESPB springs back to the RELEASED position.
Note: NOTE: The ESPB should NOT be used for normal stopping of the engine.
Pump Stop Switch
The pump stop switch (5) is optional on the 3412 engines. The pump stop switch is used in conjunction with the automatic fuel transfer system (if equipped). The automatic fuel transfer system is mounted on the generator set. When the pump stop switch is pressed initially, the pump stop switch latches into the pressed position. A red lamp within the switch illuminates at this time. Until the switch is reset, the switch will remain in the pressed position. In order to reset the switch, press the switch again. The pump stop switch is used in order to manually stop the AC fuel transfer pump. The red lamp turns OFF when the switch is reset.
Pump Run Switch
The pump run switch (7) is optional on the 3412 engines. The pump run switch is used in conjunction with the automatic fuel transfer system (if equipped). The automatic fuel transfer system is mounted on the generator set. When the pump run switch is pressed, the AC fuel transfer pump will fill the generator set's day tank. The AC fuel transfer pump is mounted on the generator set. A green lamp within the switch illuminates at this time. The pump will automatically shut off when the contactor for the fuel level reaches the high fuel level. The pump can be manually shut off by pressing the pump stop switch. The green lamp turns OFF when the transfer pump stops running.
Warning Reset Button
The Warning Reset Button allows the operator to turn off the Alarm. Activating the switch will silence the alarm for five minutes. After the five minute period, if the condition that has initiated the alarm has not been corrected, the Action Alarm will sound again.
