. Oil in separating chamber fail to flow into low pressure chamber because return valve is jammed due to big floater split and much fuel dispenser waste in return valve. Many operations without refueling lead to overflow in exhausting pipe. Fuel without data count Pin installed on the elbow of measurement transducer has broken. Replace new elbow or pin. It has some wrong in count pulse of transducer though axis is still rotated. Inspect wiring of double opticaleletric pulse, main board and chipset. Confirm that whether trouble of short circuit on wiring board. 11. Although fuel dispenser normally discharge display screen don’t show data. Failure in PPU change Using multimeter examines parameter lock whether open or closed. Computer of fuel dispenser is on power, but can’t start operation. Firstly inspect keyboard lock’s state, capacitor on wiring board. Measure voltage of power supply (�V, �2 V). Examine switch signal, change when necessary. Inspect boot-strap signal，replace new main board as signal break. Examine power supply wiring if motor stop rotation with signal. Abnormal stop in operation Inspect voltage of power supply (�V, �2 V), change the one that low voltage. Lead connection is not fixed. fuel dispenser Tight bolt fixing lead. Wire voltage of motor is unstable. Display screen trouble Change display screen with new one. If still don’t displays replace main board of fuel dispenser Keyboard trouble Replace with a new keyboard, if could work there is wrong in previous keyboard. If still don’t work with a new keyboard, trouble would be in mainboard. Computer doesn’t work on power Inspect voltage of power supply (�V, �2 V),replacing broken one. Examine SW signal; if failure replacing optical board. If SW signal is in normal state, replace main board. Date jump in display screen as hold up or put down nozzle One of reason is leakage on pipeline and bottom valve. Randomly prolong or replace non-standard pipe and hose also make this trouble on fuel dispen fuel dispenser
