Manual Extract: Operation
1) Automatic stop
1. Assemble it with the switch built-in the fuel supply pump turned ON. (No control is required for customers.) 2. Put the 3-position rocker switch to Automatic side after the key switch has been turned ON. (Center: OFF, Automatic Alternate: ON, Manual: Momentary ON.)

3. This operation allows electric power to be supplied to the fuel supply pump by way of both relays of «auto» and «main» so that fuel is pumped up into the fuel tank out of an fuel drum.
4. The controller is always monitoring quantity of fuel remained in the tank by using fuel sensor.
5. When the fuel sensor comes to the full level (Rf) position or above, the controller gives output signal to the relay (auto). (NPN output.)

6. The relay (auto) is switched over by the output signal allowing the power supplied to the fuel pump to be shut off.
7. At the same time, the buzzer sounds to inform that refueling has been made an automatic stop.
8. When the 3-position rocker switch is turned OFF, the buzzer stops sounding and automatic refueling mode is released.
9. Even if the automatic refueling mode has been released, the controller keeps on sending output signal to the relay (auto) if the position of fuel sensor is at the full level (Rf) or above.
10. The controller stops giving the output signal to the relay (auto) when the fuel sensor comes down below the full level (Rf) position.

2) Manual refueling
1. In case where automatic refueling fails functioning due to troubles such as in the fuel sensor, the controller, and the relay (auto).
2. In case where a machine cannot fill up the fuel to its full by automatic refueling.
3. Supply fuel while monitoring fuel gauge with the 3-position rocker switch turned to manual side (momentary).
4. Power is supplied to the fuel supply pump via the relay (main) from the manual switch so that fuel can be supplied to the tank.
