ur kinds of display mode: Mode I: serial BCD display, in which volume 6 digits, money or sales 6 digits, PPU or unit price 4 digits, totally 16 digits are transmitted out in means of serial mode, realizing operation of memory, coding and drive in display. Diagram 3-5: Main display board figure Mode II: serial display, in which chip transmit 16 digits including volume 6 digits, sales 6 digits and PPU 4 digits, memorizing and driving in display. Mode III and IV: parallel BCD display, in which chip transmits 16 digits codes including volume 6 digits, sales 6 digits and PPU 4 digits by means of parallel, once time one digit, memorizing, coding and driving in display. Most of fuel dispenser manufacturers recently adopt BCD serial mode to design display board, only very few adopt serial display mode. 1638300217170Display board structures are illustrated in Diagram 3-6 and 3-7. Diagram 3-6: LCD display board structu fuel dispenser re with parallel drive Diagram 3-7: LCD display board structure with serial drive Being a electric component easy to be failed, the hard structure of display board is introduced in detailed. LCD basic principle and working principle Liquid crystal a stable phase between liquid and solid in terms of thermodynamics, characteristic of not only liquidity and continuity under a certain temperature range, but crystal trait ---- long stick molecule, large proportion of width to length, a bridge between the two polarities. fuel dispenser LCD Structure illustrated in Diagram 3-8, electrodes are made various letters, number or matrix according to different requirements. Diagram 3-8: Basic structure of LCD 8-segment LCD and drive 8-segment display tube has two drive modes of static and hour-divis fuel dispenser ion. Fuel dispenser usually adopt static drive mode. Static drive circuit and wave showed in Diagram 3-9, the drive mode of LCD display is varied from that of LED display. As for LED only need to connect invariable conduct or cut off voltage to control emitting or wink of LED, but for LCD should not connect inv

is in the INOPERATIVE state when it is not possible to open a FP. The　　 reason for this is that essential configuration data (e.g. W M parameter) is missing　　 or a major error has been detected. The FP will also be in the INOPERATIVE　　 state during the changing of essential data (e.g. software download).　　 Note: Payable transaction may exist.　　 PCD Comment:　　 The PCD will indicate that an IFSF FP is inoperative when it cant open a　　 proprietary pump or when the PCD itself is unable to operate.　　 EVENT DESCRIPTION　　 OPERATIVE When the FP has been configured with the essential data to operate (W M　　 parameters pump configuration parameters) and no major errors have been　 fuel dispenser 　 detected (see 3.11 Error Code Data) the FP goes to the CLOSED state.　　 PCD Comment:　　 When the PCD detects that the proprietary FP has been configured with the correct　　 data to operate it should change the IFSF FP state to the CLOSED state.　　 Action : The FP state change is sent as an unsolicited data array　　 FP_Status_Message .　　 MAJOR_ERROR If a ma fuel dispenser jor error event occurs the FP stays in the INOPERATIVE state.　　 PCD Comment:　　 When the PCD detects a major error with the proprietary FP or with itself it must　　 leave the IFSF FP status as IN fuel dispenser OPERATIVE.　　 Action : The FP sends the unsolicited data FP_Error_Type_Mes .　　 MINOR_ERROR If a minor error event occurs the FP does not change the state.　　 PCD Comment:　　

ML-Q and its allies cannot always muster a majority, and do not support General Musharraf s more liberal proposals, this seldom happens. In almost seven years in power, the general has issued 44 ordinances, five of which have been passed into law. The others are renewed by decree every four months—or perhaps not; Pakistanis are rarely informed. Confusion envelops large areas of law, as it envelops parliament. “People are at a loss to know what this parliament does,�says Sherry Rehman, an elegant PPP member who likes to blow her cigarette smoke in the faces of the assembly s mullah members. So this is a Punch and Judy democracy show, reminiscent of those put on by a succession of earlier uniformed and civilian puppeteers. General Musharraf has proved himself as skilful as any of them. In 2002, three years after seizing power, he held a referendum on his rule in which he got a 98% approval rating. It was so grossl fuel dispenser y rigged that he apologised on national television for the “excesses�of his supporters. Yet he proceeded to hold general elections in a similar spirit. He cannibalised Mr Sharif s party to staff his new PML-Q. Nominally Pakistan s independence party, the Pakistan Muslim League has been co-opted by successive military rulers, each forming his own faction. The election was contested by six different PMLs. The PPP, Pakistan s nearest thing to a national political party, was much harder for General Musharraf to co-opt. fuel dispenser It was formed in 1967 under Zulfikar Ali Bhutto, who was ousted as prime minister in 1977 by General Muhammed Zia ul-Haq and subsequently hanged. Under the leadership-in-exile of Ms Bhutto, Zulfikar s daughter, the PPP s support has held up surprisingly well. It is fuel dispenser strongest in Sindh, the Bhuttos ancestral land, but to some degree it has become a rallying-flag for all Pakistanis who object to the army s political meddling. Had Ms Bhutto returned from exile to fight the 2002 election, with Mr Sharif s party in ruins, she would have won. General Musharraf kept
