3. Static Electricity Precautions
Electronic components used are sensitive to static. Please take anti-static precautions.
An anti-static wrist strap should be worn and connected correctly when working on any
electronic equipment. If an anti-static wrist strap is unavailable, or in an emergency, hold onto
an earthed part of the pump/dispenser frame whilst working on the equipment. This is not a
recommended alternative to wearing an anti-static wrist strap.
Note: Compac Industries Limited reserves the right to refuse to accept any circuit
boards returned, if proper anti-static precautions have not been taken.
4. Pre-installation Check
Once the pump is received on site, check that no damage has occurred while in transit –in
particular, damage to electronics due to vibration or jarring. All terminals and plugs should be
checked, including IC chips, to ensure they are securely in place.
5. Installation
Installation should be in accordance with local regulations.
The dispensing equipment shall be installed to prevent the delivery hose from contacting the
ground when not in use.
Where local regulations require a sump to be fitted:
a. Sumps must be provided at all dispenser installations with secondary containment
pipework and at all new installations; and
b. at all sites with sumps, dispensers should be installed with a liquid level detection device
fitted in the sump that will raise an alarm if liquid is detected in the base of the sump.
Important Note: Compac 400 litre per minute high flow dispensers do not have an internal
filtering system fitted at the factory. It is the customer and/or installers responsibility to ensure
the fuel supplied to the 400 lpm side of the dispenser is clean and free from any dirt, debris or
metal particles that could damage the meter or hydraulic components. A 10 micron filter is
recommended. Compac does not warranty the meter or hydraulic components for damage
caused by contaminated fuel supply.

8. Electrical Connections
Prior to pump installation ensure that there is at least a two-metre tail on the incoming
underground mains supply / pump contactor cable and comms cable (if comms enabled).
These cables are terminated at the C4000 power supply, which is housed in the flameproof
enclosure located in the bottom of the pump, behind the door.
Mains power wiring should be rated for a maximum current draw of 10 A rms at 220-240 V
ac.
Refer to AS/NZS 60079.14 for appropriate cabling.
When replacing the lid of the flameproof enclosure, ensure the sealing O ring is in place.
Note: All cables entering the power supply must be glanded with approved 20mm flameproof
glands.
Note: Output to submersible pump(s) is 230 V ac, 300 mA max. It is wired to the pump
contactor/relay at the switchboard and not directly to the pump.
Note: Pump comm’s connect to pump controller such as DCA, CommunicatorController etc.
(option). Comms cable is not intrinsically safe.
8.1 Submersible Pump connections
Connect the feeds to the submersible pump relays / contactors to the C4000 Power Supply as
follows:
Pump supplying side A to terminal marked T1
Pump supplying side B to terminal marked T4
If both sides are required to switch the same submersible pump then T1 and T4 should be
linked together.
Note: Dispensers do not use the terminals marked LOAD 1 & 2.

9. 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.
9.1 Breakaways
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.
10. Electrical Commissioning C4000
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).
1. Turn on the power supply to the dispenser.
2. 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
3. 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.
4. 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.
5. 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.
6. Hang up the nozzle (80 LPM side) or turn switch to OFF (400 LPM side).
7. Repeat the operation for both hoses.
8. To clear the error code, re-power the dispenser and then move on to the Mechanical
Commissioning and Air Purge of the dispenser.

\\Cilaklfs1\shrdata\Masters\Installation Sheets\Master & Premier\MMR400-80S Installation
Sheet.doc Page 10 of 18
11. Mechanical Commissioning and Air Purge
This procedure outlines how to perform a mechanical operational test and making sure that
the dispenser is functioning correctly. Before testing the unit, 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.
To test the unit please carry out the following tests:
1. Make sure that the electrical commissioning tests have been carried out and the solenoid
operation has been verified before carrying out the following tests.
2. Slowly open the fuel supply valves to the dispenser, checking for any leaks.
3. Turn on the power supply to the dispenser.
4. Lift the nozzle (80 LPM side) or turn switch to ON (400 LPM side).
5. 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
6. Check all the dispenser fittings, solenoids and pipework for leaks.
7. Slowly dispense fuel from the dispenser, being careful to shield yourself from splashes as
there may be air in the fuel causing it to spray from the nozzle.
8. The display and tote should increment when fuel is flowing.
9. The dispenser can now be calibrated. Refer to the C4000 Master Manual for calibration
instructions.
12. Setting up the C4000
Once the pump is connected on site, the final setup check and calibration to complete the
installation must be carried out, using the Parameter Switch and Calibration (K-Factor) Switch.
These switches are found on the C4000 Microprocessor Board which is housed in a metal
enclosure located on the left front of the unit below the display panel
12.1 Configuration Codes
The configuration code has been set at Compac and should not be changed
In the event of it being lost and having to be re-entered the configuration is written on the
yellow label on the C4000 processor board cover
12.2 Submersible Delay (Sd)
This is the time delay from when the Submersible pump starts to when the solenoids in the
dispenser open to allow time for the leak detector to reset.
This is factory set by Compac at 005 (five seconds).
If problems are experienced with the leak detector tripping, firstly check that 'Sd' is still set
and then, if necessary, make it longer as follows.
1. Press and release the K factor switch repeatedly until 'Sd' appears on the Dollar display
'dXXX' will appear in the litres display.
2. Continue to press the K factor switch until the number to be changed flashes. Hold the
switch down and this number will then increment.
3. Release the switch when the required number is displayed. The value of the displayed
number will then be stored in the C4000 memory as the Submersible delay.

12.3 Parameter Switch Settings
12.3.1 Setting the Pump Number
This must be set at the pump, for each hose, so that communications with
a controller can take place. The location of this switch is shown in the
diagram below.
Depress the Parameter Switch nine (9) or more times until the message
'PnA XX' appears in the litres display window. When the switch is
pressed again 'Pnb XX ' will appear on the display. These two options
will toggle each time the switch is pressed. To alter either of the pump numbers, press and
hold the Parameter Switch when the pump number to be altered appears on the display. This
number will then increment. The switch should be released when the desired pump number is
displayed. The value of the displayed number will then be stored in the C4000 memory as the
pump number for that hose.
NOTE: For a single hose only ‘Pn” will appear
12.3.2 Setting the Price

13. Calibration (K-Factor)
13.1 Setting the K-Factor
K-Factor is a proportional calibration factor of litres dispensed per revolution of the meter.
To calibrate the dispenser/pump, dispense fuel into a certified measuring container, and
compare the display value with the amount dispensed.
Example:
Display shows 10.00
True volume 20.00
To calculate the correct 'K' Factor from the information above; firstly record the
existing 'K' Factor.

\\Cilaklfs1\shrdata\Masters\Installation Sheets\Master & Premier\MMR400-80S Installation
Sheet.doc Page 14 of 18
13.3 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’.
14. Pump Controller
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.
15. Spare Fuses
In the event of a fuse blowing on the C4000 Power supply, a bag of three spare fuses 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.
16. Hammer when Preset amount reached
If hammer in the pipework is experienced when the dispenser reaches the end of the fill (on a
preset delivery), there is an adjustment screw on the Solenoid which may help to reduce this.
The adjustment screw has 4 positions. The factory default setting is in position 2. If hammer
is experienced try changing this setting. As there are site variables such as pressure and
length of line, try all four positions and leave in whichever position works best.
17. Precautions if Using Generator Power
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.
