This procedure outlines how to perform an electrical operational test, 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.
NOTE:
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 page 24.)
Check the pump price is set (see page 25.)
For the location of LEDs, required for this operations test, 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 C5000 processor board Power LED
is turned on.
NOTE:
If the dispenser is receiving information, RD LED on the K-Factor board will be on. If the
dispenser responds to polls for its respective pump number/s, TD LED will also be on.
4. Lift the nozzle. The display will show 888888 and the solenoids will energise,
starting the pump motor. Check that T1-3 (side A) or T4-6 (side B) turn on, indicating a
signal is being sent to the triacs to open the solenoid valves.
5. The diagnostic LED (K-factor board) 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.
6. 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.
