Usage and Maintenance As few in domestic fuel dispenser, the troubleshooting of double piston measurement transducer consult the methods of four-piston measurement transducer or maintain according to the fuel dispenser user’s manual provided by manufacturer. Some difficult trouble should consult with special mechanician from factory. Every fuel dispenser time of adjusting measurement transducer should be operated by the metrology appraisal agency exclusive, whatever structure and model. Troubleshooting also need to be authorized and content by the agency, even to be appraisal and lead seal. Article IV Nozzle Nozzle is a terminal of fuel dispenser’s hydraulic system, which is tool used to refuel into tank and other container. Thus, nozzle should be characterized, by technically, as simple operation, less losses in pressure, stable flow, adjustable, good sealbility and safety. Nozzle includes general nozzle, auto-shut nozzle and nozzle with vapor recovery device. The first type is once widely used in fuel dispenser industry, even still employed currently. With the development and demand in fuel dispenser’s technology auto-shut nozzle become available in manufacturer of fuel dispenser, as this type of nozzle add auto-shut function on the basis of general nozzle. In the current years, some manufacturers have mounted vapor recovery device to nozzle, but its market share is still small. Here introduce them except the last type. General nozzle This kind of nozzle once widely used in filing station is still adapted. 1.1 Structure As illustrated in Diagram 2-27, it consist of nozzle body, main valve, vice valve, nozzle, switch handle.

em.　　EPS The applicat fuel dispenser ion that manages the card payment application.　　Main Flow Description　　1. CashierOperator or POS application triggers the logoff.　　2. If POS fails the process is aborted and the cashier has to recover the POS.　　3. POS requests to EPS the logoff.　　4. If message invalid it is repeated or the process is aborted and the cashier receives a specific　　 fuel dispenser alarm. POS is still at the initial status.　　5. EPS accepts the logoff　　6. If EPS gets into an exception status trans fuel dispenser action not possible to complete the transaction　　 gives a negative response.　　7. If POS fails to receive a response from EPS (EPS failure) it considers the logoff failed.　　8. If EPS tells POS the response but POS has failed (e.g. fails to get the acknowledge) it　　 considers the logoff failed.　　9. If completed EPS tells POS the result (positive or negative).　　10. If successful both applications are not operative toeachotherand available for maintenance etc.　　11. If the result is negative it might be necessary to operate anyway even if more attepts fail: in the　　 end the failure is ignored.　　3.17 Part A - use case: Send Offline Transactions　　In case the EPS application would support off-line transaction authorisation these transactions must be　　forwarded to a host. Regardless how this is accomplished by the EPS application (e.g. ftp) this delivery　　might be triggered by the cashier or the POS application for some reasons.　　Pre-Conditions　　The cashierSiteManager wants to trigger the off-line transaction log transmission or the POS Sell　　applications triggers it upon a time set or match of predefined conditions.　　The POS application is logged on with the EPS application.　　There is no pending message between the two applications from that workstation.　　Actors　　Actor Description　　Cashier Person who might trigger the operation on the POS Sell applicat
