acklist, etc. Once found something wrong, it will obtain latest data from Center controller. Anti-low temperature The minimum limitation of working temperature is �0℃on general fuel dispenser. But on IC card fuel dispenser,�0�due to employ temperature control device. Turn on the device when necessary. Apart from the above functions IC card fuel dispenser should be provided with these traits such as explosion-proof electric safety, anti-dust, anti-interference, high applicability of power supply, high reliability, low ratio of failure, convenient for combination and expansion. Article IV Fuel dispenser and reader working flow Refueling process Under normal situation, filling process should be like this: When power supply is connected, the whole system begins to initiate. As CPU get fuel dispenser open command (nozzle has switched on) motor is startup; small flux solenoid valve switch on, oil flowing out of nozzle; CPU calculates volume filled according to pulse transmitted by sensor; at same time, large flux solenoid valve is open, being large filling state. Metering circuit counts paid volume and money on basis of pulse sign transmitted by flow sensor, then transmit these data and unit price into CPU that control the display of current filing. Metering CPU, if in randomly filing, will switch off solenoid valve and motor to end filing when receive stop sign (nozzle has switched off). If in presetting filing process, metering CPU will firstly close large flux solenoid valve when paid volume approaching to presetting volume (100ml~~300ml), small flux solenoid valve being open until paid volume is equivalent to presetting volume. Finally, current filing information such as filled volume, money and unit price (PPU) i fuel dispenser s transmitted into CPU and display on screen. The proportion of large flux to small flux is 10 to 1. The knowledge of fuel dispenser’s normal working procedure is of importance to judge trouble and failure.
