Electrical Commissioning C4000
This procedure outlines how to perform an electrical operational test
before carrying out full mechanical commissioning and making sure that
the dispenser is functioning correctly. Check for any damage that may
have occurred in transit. Check all terminals, plugs, and chips to make
sure that they are securely in place.
Damage to electronics occurs most commonly from
vibration and jarring.
Before beginning this test, check that fuel has not been applied to the
dispenser. The factory set-up information should be programmed into
the dispenser but all K-factor and Parameter switch settings should be
checked and confirmed before commissioning tests are carried out.
Check that pump number is set. See Setting the Dispenser/Pump
Number (see page 37)
Check the pump price is set. See Setting the Price per Litre (see page
34)
To perform an electrical operational test:
1. Make sure that the inlet shut-off valves are closed (these are the
valves in the inlet lines at the base of the dispenser, but they are not
part of the dispenser).
2. Turn on the power supply to the dispenser.
3. With the dispenser in a ready state, check that the C4000
Microprocessor Power LED (D1) is turned on
If the dispenser is receiving information, Comms RXD
LED (D6) will poll. If the dispenser responds to polls for its
respective pump number/s, Comms TXD LED (D7) will also poll.
 Diagnostic LED (D18) slowly flashing. (If the dispenser is
connected to an operational Controller, it flashes slowly but
erratically. If the dispenser is not connected to a Controller, it
flashes slowly and consistently.)
 Watchdog LED (D5) is turned off
4. Lift the nozzle
The display will show 888888 and the solenoids energise,
starting the pump motor. Check that Diodes D8, D10 and D11 turn
on, indicating a signal is being sent to the triacs to open the solenoid
valves.
The diagnostic LED (D18) flashes quickly when the start button is
pushed or the nozzle removed from the holster to initiate a fill. When
the button is released or nozzle returned to the holster it will return
to the normal state and flash slowly.
5. Verify solenoid operation by listening for a click, or by using a
screwdriver tip or some other metallic tool to check for a magnetic
field present on the solenoid coils.
The solenoids will switch off after four minutes. This is a default
time-out setting in the software for situations when there is no fuel
flow registered.
