Standalone Operation

11.3
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.
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'.

Pump Controller

12.
If the pump is connected to a controller, check that pump data and transaction information is
being correctly uploaded to it. Refer to the controller manual for specific instructions regarding
connection and setup.

Spare Fuses

13.
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.

Precautions if Using Generator Power

14.
The power output from onsite generators can cause power spikes that may damage electrical
components within the cabinet. When connecting to sites powered by generators, please take
the following precautions:
1) Install a power conditioner. Although generators are fitted with power regulators, most are
not filtered sufficiently for powering sensitive electrical components. We recommend
installing a commercial power conditioner and/or UPS between the generator and the unit.
2) Starting up. Before starting a generator, make sure the power to the unit is turned off.
Start the generator, let the generator reach stable operating speed and wait 30 seconds
before reconnecting the power to the unit.
3) For units where the generator starts and stops on demand, install a delay timer or PLC to
automatically isolate the unit until the operating speed and consistent power output is
achieved.
4) Isolate the unit before shutting down the generator.
