    layers of oil resistance and erosive resistance. Single thread and aluminum wire are prohibited. Diagram 5-7: Wiring in TN-S Power supply system The connection between fuel dispenser and distributing room adopts bushing-pipe burry, preventing vehicle crush wires. The wire pipe installed at bottom of fuel dispenser should have downward elbow in case oil pouring into and erode wire. No jointer is set between the pipeline of junction box and wire outlet, in case of sparkle jeopardy. User’s wire should correspond to earthing line and power lines after importing exploision-proof junction box. Tighten nut and clamp wires ensuring the explosion-proof performance. Change one of three wires if motor does not work. If adopting TN-S power supply system, wiring from switchboard are connected as diagram 5-7 illustration. If adopting TN-C-S OR TN-C system, wiring as Diagram 5-8. Gro fuel dispenser unding of fuel dispenser is in well condition. It is to adopt brass wire with PVC insulting bushing as communicating line between fuel dispensers. Communicating line is buried in galvanized pipe. Diagram 5-8: Wiring in TN-C-S or TN-C Power supply system Fuel dispenser should set single earthing line, with resistance no more than 4Ωto earth, 10 Ωnozzle to earth. User’s wire should adopt copper line with no less than 6mm2 section in single phase motor. Otherwise, there is something wrong with motor, even resulting in electric trouble. Diagram 5-9: Wiring Diagram of Communicating Box Article II Submersible pump type dispenser and its installation Compared with fuel dispense mounted suction pump, submersible pump fuel dispenser has many merits such as low noise, stable operation, cost-efficient pipeline, and is installed in large station, which is the development direction of fuel dispenser industry. Submersible pump fuel dispenser consists of main frame, submersible pump and electric control box, which are communicated through electric and signal cable. See Diagram 5-10.

technical specification

    xt   check is whether the field value is legal. IFSF specifications are not tolerant of   type mismatching. If the field is bcd8 then 4 and only 4 bytes can be sent. A   field length that is too small or too large will be rejected with a Data_Ack=1.   In the two examples that follow the logical node address (Data_Id=02) is   attempting to set to 0A and then attempting to set to 0A0A0A. Both fail with   the same MS_Ack of 5 and Data_Ack of 1.   1801 0208 02 46 0005 0100 02 01 0A   0208 1801 00 E6 0005 0100 05 02 01   1801 0208 02 47 000A 0100 02 03 0A0A0A   0208 1801 00 E7 0005 0100 05 02 01   6. The final level of checking is whether the value is itself valid. We fuel dispenser have already   determined that the field is legal i.e. we expect a a single byte for the   Max_Block_Length (Data_ID=05) in the communication services database but   the specification says it has a range of values from 32 to 228. Thus if a value   of 0 up to and including 31 is sent then the write is rejected with an MS_Ack   of 5 and Data_Ack of 1. Here is an example using a value of 15 (0E) and a   token value of 08:   1801 0208 02 48 0005 0100 05 01 0E   0208 1801 00 E8 0005 0100 05 05 01   If the the data is valid then a successful write gives a MS_Ack of 0. Examples are   given in chapter 5.2.2 earlier.  5.4 Data_Ack Error Handling   The Data Acknowledge Status is used to indicate in the Acknowledge message if the   request has been accepted or the reason for rejection. There may be more than one   reason for rejecting the request so the order of error checkin fuel dispenser fuel dispenser

    t risk. In Lewes, for example, hard hit in 2000, a survey in 2003 found that a quarter of respondents had had their premiums substantially increased and nearly a fifth could not renew their policies at all. The government too is breaking its side of the bargain. Spending on flood defences was increased from 2003, but official enthusiasm for building new flood barriers is waning. In July the Environment Agency s budget for flood-risk management was cut by almost £15m, reversing a promise made just eight months earlier to maintain spending at current levels in real terms. Even if that promise were kept, however, it would not be enough. Although London is well protected by the Thames Barrier, rising oceans will make the city s defences obsolete by 2040, says David Crichton, of the Benfield Hazard Research Centre. Spending on flood defences may have to rise by £10m-30 fuel dispenser m per year in coming decades to cope with the effects of global warming, according to a government study on climate change. The Association of British Insurers (ABI) wants the government to raise its investment by 10% a year to £750m by 2011. By providing what is effectively subsidised insurance, the agreement has encouraged building in silly places. The Environment Agency reckons that some 570,000 homes and businesses are now in great danger of being flooded. Yet more are still being built. As many as 200,000 new properties are scheduled for development in flood plains, says Royal & Sun Alliance, an insurer. More than 1,000 planning applications were approved between 2002 and 2005, despite recommendations to the contrary from the Environment Agency. Insurers have already said they are reluctant to cover them. This presents the government with a thorny problem. It wants thousands of new homes to be built in the Thames Gateway, a flood plain to the east of London, but no bank will finance their construction unless they can be insured. Pressing ahead with those plans will mean spending billions more on flood defences, or p fuel dispenser fuel dispenser
