You must adhere to the following safety precautions at all times when
working on the Compac C4000 processor. Failure to observe these safety
precautions could result in damage to the Compac C4000 processor, injury,
or death.
Make sure that you read and understand all safety precautions before
operating the Compac Compac C4000 processor.
Mechanical Safety
Observe the following mechanical precautions:
Make sure that the service area is thoroughly clean when
servicing. Dust and dirt entering the components reduce the life span of the
components and can affect operation.
Electrical Safety
Observe the following electrical precautions:
Always turn off the power to the Compac C4000 processor
before opening the flame proof box. Never touch wiring or components
inside the high voltage area with the power on.
Always turn off the power to the Compac C4000 processor at
the mains switch before removing or replacing software or memory ICs.
Always take basic anti-static precautions when working on the
electronics, i.e., wearing a wristband with an earth strap.
Safety Precautions
The C4000 head, and its associated circuits and wiring, is a
certified piece of electrical equipment approved for use in a hazardous area
(Class 1 Zone 1, Group IIA T3). Only parts identical to those covered by the
certification may be used where the integrity of the intrinsic safety may be
affected. All circuit boards are to be repaired only by Compac Industries
Ltd.
Static Electricity Precautions
Electronic components used are sensitive to static. Please take anti-static
precautions.
All circuit boards must be carried and transported in static-shielded bags.
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.

Electrical Commissioning C4000
This procedure outlines how to perform an electrical operational test
before carrying out full mechanical commissioning and 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.
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 Setting the Dispenser/Pump
Number (see page 37)
Check the pump price is set. See Setting the Price per Litre (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 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
4. Lift the nozzle
The display will show 888888 and the solenoids 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.
5. 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.

Set-up Modes
To enable the C4000 to operate as desired two things must be set:
1. Configuration (K Factor) Switch Settings
Refer C4000 Set-Up K Factor Switch Settings (see page 21)
This switch accesses different options that must be set appropriately for the
particular type of dispenser.
2. Parameter Switch Settings
Refer Parameter Switch (see page 33)
This switch is used to conduct the Display Segment Test, set price (product
density - if a bulkmeter or LPG), and set pump number. Also, when the
C4000 is configured for 'Comcard', 'Compin', or 'CWIDKey' the parameter
switch is used for card/pin/key validation and for setting the card/key
system number
Configuration Code
The C4000 pump/dispenser software, the configuration code (used to set
the pump/dispenser to single, dual or multi mode) has been extended to 5
digits. When configuring the pumps/dispensers, the litre display will display
each digit.
For FUTRA software configuration options, see the FUTRA
service supplement.
Multi-hosed Pump/Dispenser with LPG
An MPD with LPG is configured by setting digits 5=3 and 4=5.
With COM125 magnetic or Bennett meters, to set LPG compensation and
motor spirit without correction, set digit 1=4.
For COM125 optical meters when motor spirit correction is required as well,
set digit 1=6.
Refer Setting the Configuration Code (see page 16)
Setting the Configuration Code
Refer to Figure 3. While setting the configuration code, the price display
shows 'C' and the volume display shows 'XXXXX'.

Figure 2 'b'Settings
Auto Authorise (Digit 4)
0: If digit 4 is set to zero, then the pump/dispenser software defaults
to conventional operation, (i.e. the nozzle switch controls the pump start
after initial authorisation).
1: If digit 4 is set to one, then the dispenser/pump software will run in
the AUTO AUTHORISE mode of operation (used for wharf & aviation or
any other sites where the hose reel is remote from the pump unit):
The pump/dispenser will start automatically after it has been initialised
by the card-reader or remotely by a Compac controller.
The dispenser/pump will switch off after four minutes if flow does not
commence.
The pump/dispenser will switch off XXX * seconds after flow rate stops.
Can be adjusted to clients' requirements, between 1 and 256 seconds
The nozzle switch becomes a shut-off switch (i.e., the nozzle switch
can be replaced with a stop pushbutton or normally closed toggle
switch).
In AUTO AUTHORISE mode the nozzle input must be
shorted out.
Transaction Data (Digit 3)
0: If digit 3 is set to zero, the system will function as a conventional
dispenser/pump and the sale data goes through to Point of Sale as soon as
the preset is reached. This is the default setting.
1: If digit 3 is set to one, the system will function as a convention
dispenser/pump but the sale data will go through to the Point of Sale only
after the nozzle has been hung up.
Set-up Modes
'b' Settings
Compac Industries Ltd.
Page 19
www.compac.co.nz
2: With digit 3 set to two, the head is set up for Comcard Basic,
Compin Basic, or CWIDKey Basic, which are self-contained systems
operating independently of any controller.
To operate, a card-reader/CWIDKey reader must be plugged into the 'head'
and the correct access code and card/key number validations must be set
by the Parameter switch.
For the Bulk Meter Register, digit 3 must be set to zero or
one. Comcard, Compin, and CWIDKey Basic systems are not available in
this mode.
Price per Litre (Digit 2)
0: If digit 2 is set to zero, the price per litre is displayed as dollars per
litre ($0.000)
1: If digit 2 is set to one, the price per litre is displayed as cents per
litre (000.0 cents).
For CNG Only: If digit 2 is set to one then the display that normally shows
the dollar value of the transaction, will display the CNG pressure during the
fill. At the end of the fill the display will revert to displaying the value.
Controller Option (Digit 1)
The function of this digit (1) depends on whether the head has been set up
as one of the Basic Systems (Comcard, Compin, or CWIDKey) or a
conventional pump/dispenser, using digit 3.
Basic Systems: (digit 3 set to two)
With all Compac pumps/dispensers, the 'head' will display the dollars and
litres grand totals when the nozzle switch is pressed quickly five or more
times.
On a commercial pump/dispenser with litres-only display, only
the total litres can be read.
If the 'head' is set-up as a Comcard, Compin, or CWIDKey Basic system
then, after displaying the grand totals as above, the head will also printout
the totals for each card/pin/key, irrespective of the digit 1 setting.
By setting digit 1 to one, the 'Scrolling Totes' option is selected. Refer
Displaying and Printing Totals (see page 41). In this mode of operation,
after printing the totals as above, the 'head' will flash card totals on the
pump's main display. All non zero card totals are displayed consecutively,
for 10 seconds each.
The totals can only be zeroed by replacing the memory chip.
Conventional Pump/Dispenser (digit 3 set to zero or one)
If digit 1 is zero, the pump/dispenser can be operated in 'stand-alone' mode
irrespective of the pump/dispenser number loaded.
If digit 1 set to one, the pump/dispenser will not work in 'stand-alone' mode,
(i.e., it requires initialisation from a controller).
The pump/dispenser ceases to work in 'stand-alone' mode if
digit 1 is set to zero and it is connected to a controller. Generally on retail
forecourts, this switch should be left off. Hence, if the forecourt controller
breaks down, the dispensers/pumps can be set to work in the 'stand-alone'
'b' Settings

mode simply by turning them OFF for 1 minute minimum, then back ON.
However, for unattended situations (e.g. truck stops), the pumps must not
be left able to work in the 'stand-alone' mode in case of a controller failure.
Therefore, digit 1 should always be set to one for unattended operation.
For the Bulk Meter Register configuration, when digit 1 is zero, the unit will
work in the 'stand-alone' mode. When digit 1 is one, the unit must be
connected to a Compac Central Controller.

The K Factor setting should be done last of all (i.e. until
parameter switch settings are made, the pump/dispenser may not be
operational, and so a calibration fill may not be possible).

1
Ensure that the nozzles are
hung up
Dispenser in idle state
2
Press and release the „K‟
Factor switch, in quick
succession, until the
desired setting is displayed.
The price display and volume
display indicates the desired
setting. See following
paragraphs.
3
Press and hold the „K‟ factor
switch.
A digit, of the displayed setting,
will begin to increment.
4
When the digit is correct,
release the „K‟ Factor
switch.
5
Repeat steps 3 and 4 for
each digit of the setting
The C4000 will
reset itself if the „K‟ factor
switch is left for more than 10
seconds.
Continue for multiple hose units, if appropriate.
6
Press and release the „K‟
factor switch 8 or more
times in quick succession
The setting for side “B” (or
hose 2, 3, or 4) is displayed.
7
Repeat steps 3 to 5 above.
The C4000 will reset at any stage during the 'K' Factor
operation if the switch is not pressed for ten (10) seconds. If the C4000
resets out of any field before the numbers have been set correctly, then that
field must be entered again to ensure the details are correct.
The K-Factor switch must be sealed with a lead or paper seal
after commissioning.

Calibration ('K') Factor
The 'K' Factor is a ratio of litres dispensed per revolution of the meter.
Below is the method of calibration, including how to calculate the new 'K'
Factor and how to enter it in the C4000 memory.
(See also Encoder (see page 55) for more information on the
encoder/pulser)
Calibration
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.

Once the dispenser/pump resets with the correct 'K' factor
entered, the display will show the new volume unless the 'head' is in
"Compensation Mode", in which case the display volume will not change.
Be careful when calibrating dual or multi-hose pumps &
dispensers to ensure that the correct 'K' factor is being changed.
