Standalone Operation
In standalone operation, the dispenser will continue working when not connected to a controller.
'Stand-alone'
mode being when no authorisation of fills is required and so fills are simply
initiated by removing the refuelling assembly from its holder. If standalone operation is inhibited,
the dispenser will not work in
'stand-alone'
mode, regardless of whether the dispenser is
ON
LINE
to a controller or not.
The dispenser ceases to work in
'stand-alone'
mode if connected to a controller, regardless of
the position of standalone setting.
Generally on retail forecourts the dispenser should be set-up for standalone operation. Hence, if
the forecourt controller breaks down the dispensers can be set to work in
'stand-alone'
mode
simply by turning them off then on again.
For unattended refuelling sites, the dispensers should not be able to work in
'stand-alone'
mode
in the event of a controller failure. Therefore the dispenser should be set-up to inhibit
standalone operation.
This is set in the 'b' code on the K factor switch.
The 'b' code to run Standalone without Dispenser Controller is ‘0000’.
The 'b' code to inhibit Standalone is ‘1000’.

Spare Fuses
In the event of a fuse blowing on the C4000 Power supply a bag of 3 is included in each
flameproof box. Any fuses used from this bag should be replaced
Note: There are three different ratings used. If replacing a fuse, ensure that the correct value is
used.

AdBlue specific instructions
18.1
Cleaning the AdBlue Nozzle
If AdBlue evaporates it may form crystals around the dispenser nozzle. A build up of crystals can
block the air passage causing the nozzle to continuously trip off.
If this occurs, rinsing the nozzle in a bucket of warm water will dissolve the crystals and unblock
the air passage.
To avoid contamination of the AdBlue, thoroughly dry the nozzle after rinsing.
