DescriptionThe gauges and warning lights which form the instrument panel are grouped in a single instrument containing:electronic speedometerelectronic rev counterpetrol gauge, with reserve warning lightLPG gauge, with reserve warning lightwarning lightsmultifunction display (milometer/trip recorder - external temperature gauge - oil level gauge - digital clock - Trip computer).The LPG level is displayed via electronic circuitry inside the actual module which operates the 6 green LEDs proportionally to the level measured in the LPG circuit.The internal logic 'dampens' the signal, preventing fluctuations (e.g. the reading changes when the signal persists for at least 250 ms. ).768

The last green LED going out, with only the amber warning light on, instead indicates that the LPG is completely finished and that the changeover to the petrol fuel supply is taking place automatically, with the relevant warning light coming on.

The instrument has direct supply lines and supply lines controlled by the ignition protected by two fuses located in the junction unit.

Functional description The supply controlled by the ignition (INT) for the instrument E50 reaches pin 19 of connector A from the line protected by fuse F1 of the junction unit B1 . The instrument E50 is also supplied directly by the battery - pin 17 of connector A - via the line for the maxifuse J/B1 of B5 protected by fuse F10 of the junction unit B1 . Pin 18 of connector A is earthed (electronic earth).Pin 1 of connector B is earthed (power earth). Pin 15 of connector A receives a reference earth from the engine management control unit M10 . Pins 2 and 16 of connector A receive signals coming from the fuel gauge, located in the electric pump unit N40 : these signals, processed by the internal electronic device, operate the fuel gauge and the reserve warning light. The LPG level sensor K33 , located on the tank itself, is supplied via the ignition (INT/A) by the line protected by the fuse B27 ; it sends a signal proportional to the LPG level to pin 32 of the control unit M18 . The LPG pressure sensor K53 , located on the pressure regulator, receives a reference earth and supply from the LPG control unit M18 - pins 16 and 22 - and sends a signal proportional to the LPG pressure to the control unit M19 - pin 30; The control unit M18 processes the two signals (level and pressure) and sends a signal - from pin 60 - to the instrument E50 , pin 9 of connector A. On the basis of this signal, the instrument E50 controls the indicator LEDs (green) and the reserve led (amber). Insufficient engine oil pressure is signalled to pin 18 of connector C from the earth signal coming from the sensor K30 . The signal from the sensor K20 reaches pin 13 of connector C and lights up the brake pad wear warning light. The signals for the handbrake switch l40 and the brake fluid level sensor K25 reach, respectively, pins 11 of connector A and 15 of connector C of E50 and light up the low brake fluid level / handbrake warning light. The same warning light is on - together with the ABS failure warning light - if the ABS control unit detects problems involving the EBD function 2889551SeeE7020ABS . The 'doors open' signal, coming from the alarm control unit M30 or coming directly from the switches in the door locks reaches pin 5 of connector B of E50 . The inertia switch I50 intervention signal reaches pin 3 of connector A of E50 : under these circumstances the instrument panel produces the appropriate signal. The speedometer sensor K84 located on the gearbox is supplied from pin 20 of connector A of E50 and sends a signal to pin 5 of connector A: this signal, processed by the internal electronic device, operates the vehicle speed indicator and the milometer and the output is available: from pins 30, 31 and 32 of connector A for the engine management control unit, the navigation system, the taxi-meter, etc. The engine rpm signal reaches the engine management control unit M10 at pin 6 of connector A of E50 : this signal, processed by the internal electronic device, operates the rev counter. A 'fuel consumption' signal, used by the trip computer, reaches pin 7 of connector A of E50 from the engine management control unit M10 .
