is illustrated in Diagram 5-13 and 5-14. It consists of controller, explosion-proof motor and co-axis vane pump. The inlet height of submersible pump is 150~250mmm from tank bottom. The motor lead of submersible pump is installed in capacitor box of upper controller. Exterior power supply is connected into junction box of lower controller. After carefully inspection submersible pump and guiding pipe are mounted into 4’�supporting pipe through lower controller, upper and lower part of controller are connected with screws in tank. Diagram 5-12: D421 Junction box wiring 2. Submersible pump wring The wiring of submersible pump is finished in controller, power supply and grounding line integrated in junction box that is sealed by rubber gasket. Connect the two black lines of power supply and controller, grounding line being fixed in junction box. The motor lead, black, brown and blue, respectively, are connected into capacitor box and sealed with rubber gasket. To connect the black lead of motor with th fuel dispenser e black in controller; brown with one of pins of capacitor, blue lead with the other terminal of capacitor after connecting with another black lead.

Fuel dispenser debugging 3.1 It is absolutely prohibited to debug fuel dispenser using water rather than oil or fuel. Debugging procedure of fuel dispenser A universal inspection should be conducted before first debugging of fuel dispenser, eliminating various elements that affect operation, lead connection in particular. Computer display screen and presetting display should be carefully examined as switching on power, lighter in electric box also being check. Starting up suction pump and open nozzle, carefully examine all connection and sealed jointer face in case of leakage and penetration. Confirming each nozzle is corresponded to its produ fuel dispenser

similar stance “Creativity, innovation and a free and open marketplace are all at stake in this fight,�he said. Such self-styled defenders of the internet like to portray the net-neutrality debate as a fight to stop evil telecoms firms messing with freedom and innovation. The reality is rather more complicated. For a start, the internet is not, in fact, neutral today. Fast broadband connections already cost more than slower ones, for consumers and businesses alike. As well as buying fast pipes and building huge “server farms� big companies such as Google and eBay also pay extra for specialist “content delivery�services, such as Akamai, to make their websites download even faster. None of this has hampered innovation or hurt small companies. It is also rather odd to see internet activists, who are generally suspicious of government intervention, calling for regulators to step in and pass new laws in the name of freedom. Laws mandating net neutrality could, in fact, do a great deal of harm. En fuel dispenser suring “neutrality�could require regulators to interpose themselves in all kinds of agreements between network operators, content providers and consumers. Content-delivery services, such as Akamai s, might suddenly become illegal. Strict rules could also hinder the development of new services tha fuel dispenser t depend on being able to distinguish between different types of traffic. And it does make sense, after all, to be able to prioritise telephony and video traffic over e-mails. “We are talking about some people getting a better service if they are prepared to pay for it,�says Forrester s Mr Godell. By dressing up the net-neutrality debate as a fight for online freedom, however, Google, eBay and other big internet firms have cleverly diverted attention from an unpleasant truth. As telecoms firms around the world upgrade their networks, there are two ways in which they can recoup the money. They can simply charge subscribers more; or they can pursue new business models in which big int fuel dispenser
