    operate m fuel dispenser otor. If it still don’t move or slowly run, electric circuit or motor should be inspected. If not the rotor of pump maybe locked. Carefully check and cleanse oil strainer. If failure still exists after the above inspection, overflow valve should be checkup. In case that valve core jam, shut down incompletely or lose in valve seat the oil in high pressure area overflow into negative area, resulting in no delivery or inefficient discharge. Taking out valve core and spring so as to clean dirty, inspect valve seat at same time. If valve seat is loose re-fix it through oil-resistant glue or change a new pump. When find scrap of spring and graphite, washing overflow valve is must, changing broken parts if necessary. If found rotor is stuck there would be several reasons related, such as spring broken, long vane, vane segment, lo fuel dispenser se bolts at top cover, etc. reassembling after overcome these reasons. Some manufacturers adopt new spring material evading broken. The lose match of rotor and axis of pump also result in no delivery or inefficient discharge. This situation will be overcome by changing rotor. After the above check and examine still find any rotor stuck or overflow valve abnorma fuel dispenser l, it is suggestive that vane abrasion is extensive, broken and spring damaged. Much abrasive vane can not successfully segment high and low pressure area, resulting no delivery or inefficient discharge as the areas exchange. The broken vane or spring not only cause flow trouble but also increase noise as whole. Furthermore, if they flow into other inner components may result in new failure. The solution to this is to change new vane or spring and clean out broken piece. It is suggestive that change all vanes if fuel dispenser have operated long time. Changing a new pump overcomes too large abrasion between frame and rotor. To check whether a leakage occurred in pine between fuel dispenser and tank, different diameter of pipe connection, bottom valve stuck or leakage. Abnormal noise and vibration The reason of

DEVICE_STATUS - Bit 1 is set i.e. Configuration Needed means that all data that is   needed for correct operation is not available. Example: In the case of power loss a   dispenser should send a Configuration Needed heartbeat since it can not know if it has   the correct prices.   NOTE - To allow devices on the same network to have different heartbeat intervals   each device should read the other heartbeat intervals and use these (x3) before   deciding not to send unsolicited messages to that device. Note this means Controller   Devices must impl fuel dispenser ement the communication service database.

    the Feder fuel dispenser al Electoral Tribunal, which has until the end of August to adjudicate any legal challenge to the vote. In the past, the tribunal has annulled state and local elections. But observers of the presidential vote have not reported the kind of widespread irregularities that might justify such a decision. The week began with a preliminary count by the institute showing Mr Calderón ahead by some 400,000 votes. For the official count, ballot boxes were moved from over 130,000 polling stations to 300 district headquarters. The tally sheets attached to the ballot boxes were scrutinised; where irregularities were suspected, individual ballots were recounted. Earlier, Mr López Obrador s supporters had complained that almost 3m votes were excluded from the preliminary count. On July 4th, Luis Carlos Ugalde, the institute s presi fuel dispenser dent, admitted this was so. They had not been counted for technical reasons, such as illegible handwriting on the tally sheets, he said. This was in line with a little-publicised agreement between the parties. But some of Mr López Obrador s supporters recalled the presidential election of 1988. On that occasion, Cuauhtémoc Cárdenas, a left-wing dissident from fuel dispenser the ruling Institutional Revolutionary Party (PRI), was leading until the computers tallying the votes mysteriously crashed. Yet that parallel only serves to show how far Mexico has changed. In 1988, the election and the count were run by the interior ministry, and the government controlled the media. Mexico is now a democracy. The institute became an independent body in 1996. In 2000, it supervised an election that saw Vicente Fox, of the PAN, end seven decades of rule by the PRI. It is unfortunate that the institute s current governing council does not include members of Mr López Obrador s Party of the Democratic Revolution (PRD), though that is because of partisan manoeuvring in Congress for which the party was partly responsible. But there is no evidence that the institute has acted in bad faith. Mr
