If the Output LED T10 is ON in your Compac Dispenser, it indicates an error state exists. To resolve this, remedy the cause of the error (i.e., Display, Memory, or KG meter) by checking the Fault Codes section. Then, clear the error by quickly pressing the start button or nozzle switch five times to view the totes.
Why are the C4000 electronics not working in my Compac Dispenser?
If the C4000 electronics in your Compac Dispenser are not working, with the indicator LEDs off and no response when lifting the nozzle, it could be due to unacceptable voltage spikes causing the fuses on the C4000 to blow. In this case, fit a voltage-stabilizing UPS to the dispenser. Another reason could be low input voltage, so turn the dispenser off and then on again, and check the power supply connections and input voltage to the dispenser with a multimeter. A voltage-stabilizing UPS will also be required.
Why does the Compac Dispenser pressure gauge creep past 200 bar when not in use?
If the dispenser pressure gauge creeps past 200 bar when the Compac Dispenser is not in use, it could be because the regulator center seal is damaged, so replace the Regulator Valve Seals. Alternatively, the solenoid piston seal might be damaged, so replace the Solenoid Valve Seal.
What does it mean when the watchdog LED D5 is illuminated on a Compac CNG?
If the watchdog LED D5 is illuminated on your Compac Dispenser, it indicates that a processing fault has occurred. To resolve this, turn the power to the dispenser off and then on again to reset the watchdog. If the light still illuminates, there may be a fault on the C4000 microprocessor board, such as a loose memory chip or a broken track. In this case, replace the C4000 memory and software chips. If it doesn't help, replace C4000 processor board.
Why does the Compac Dispenser stop at 9999.99, 99999.9, or 999999 units?
If the Compac Dispenser stops at 9999.99, 99999.9, or 999999 units, it is because the dispenser will stop dispensing if either the value or the quantity displays ever reach these values. To resolve this, hang up the nozzle to reset the display and restart.
What to do if a display LCD segment is always on or off on Compac Dispenser?
If a display LCD segment is always on or always off on your Compac Dispenser, it indicates a faulty display unit. In this case, replace the Display PCB.
