Dispensing Hoses and Nozzles

The unit may or may not be supplied with dispensing hose and nozzle assemblies.

If customer supplied hose assemblies, pylons, reels, safe breaks and nozzles are used they

must comply with the requirements outlined in AS/NZS 222.

Breakaways

9.1

For all dispensers fitted with breakaways, ensure the breakaway is installed between the

nozzle and the high-mast or pylon (if fitted). Any breakaways that have been subject to a

break-away situation should be inspected and refitted or replaced in accordance with the

original manufacturer's instructions.

Electrical Commissioning C4000

10.

Before beginning this test, check that fuel has not been applied to the dispenser. The factory

set-up information should have been programmed into the dispenser but all K-factor and

Parameter switch settings should be checked and confirmed before commissioning tests are

carried out.

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).

Turn on the power supply to the dispenser.

With the dispenser in a ready state, check that the C4000 Microprocessor Power LED (D1)

is turned on.

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

Lift the nozzle (80 LPM side) or turn switch to ON (400 LPM side).

The display will show 888888 and the solenoids will 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.

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. If there is air in the system,

the display may show an error code.

Hang up the nozzle (80 LPM side) or turn switch to OFF (400 LPM side).

Repeat the operation for both hoses.

To clear the error code, re-power the dispenser and then move on to the Mechanical

Commissioning and Air Purge of the dispenser.
