COMPAC INDUSTRIES LIMITED C4000 SERVICE MANUAL SET-UP MODES
31 May, 2004 Page 7
3. SET-UP MODES
To enable the C4000 to operate as desired, two things must be set:
1. Configuration (K Factor) Switch Settings
°This switch accesses different options that must be set appropriately for the particular
type of dispenser.
2. Parameter Switch Settings
°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 (access code - refer section
3.3.8).
°With CNG dispensers, the sequencing rate between 'banks' is also set using the
parameter switch (reference section 3.3.6).
The positions of the above switches are shown on Figure 1, page 1. Set up of the C4000 must
be done in the following sequence:
1. ‘K’ Factor Switch Settings - starting with configuration setting and moving back
through the options to the K Factor setting:
‘K’ Factor Switch Settings

SET-UP MODES C4000 SERVICE MANUAL COMPAC INDUSTRIES LIMITED
Page 8 31 May, 2004
NOTE: 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).
2. Parameter Switch Settings - all must be set, but the order of the set-up is not critical.
3.1. 'K' Factor Switch
The 'K' Factor switch is located on the C4000 PCB as shown in Figure 1 on page 1. The 'K'
Factor switch is used to access and change various set-up options of the C4000 head. The
following flow charts detail the operation of setting up the C4000 head:
Any change of set-up effected by the 'K' Factor switch takes effect as soon as the C4000
resets. The power supply does not have to be interrupted.
NOTE: The C4000 will reset at any stage during the 'K' Factor switch operation if the switch is not pressed for
a period exceeding 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.
3.1.1. Using the ‘K’ Factor Switch
Using the ‘K’ Factor Switch to Change a Setting
Step ACTION RESULT
1Ensure that the nozzles are hung up Dispenser in idle state
2Press 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.
3Press and hold the ‘K’ factor switch. A digit, of the displayed setting, will
begin to increment.
4When the digit is correct, release the
‘K’ Factor switch.
5Repeat steps 3 and 4 for each digit of
the setting
NOTE: the C4000 will reset itself if the ‘K’
factor switch is left for more than 10 seconds.
Continue for multiple hose units, if appropriate.
6Press 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.
7Repeat steps 3 to 5 above.
IMPORTANT NOTE:
The K-Factor switch must be sealed with a lead or paper seal after commissioning.
3.1.2. Calibration ('K') Factor
(See also section 0 for more information on the encoder/pulser)
The 'K' Factor is a ratio of litres dispensed per revolution of the meter.
To follow is the method of calibration, including how to calculate the new 'K' Factor and
how to enter it in the C4000 memory.
Calibration
To calibrate the dispenser/pump, dispense fuel into a certified measuring container, and
compare the display value with the amount dispensed.

COMPAC INDUSTRIES LIMITED C4000 SERVICE MANUAL SET-UP MODES
31 May, 2004 Page 9
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.

Note: 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 (see
section 3.2.5).
Caution: Be careful when calibrating dual or multi-hose pumps & dispensers to ensure that the correct 'K'
factor is being changed.
3.1.3. No Flow Cut-Off Timer
Under normal conditions to end a transaction on a C4000 controlled pump/dispenser, there
are three possibilities:
•Returning the nozzle to its holder.
•Reaching the preset amount entered.
•Cut out on the 'No flow cut-off timer'.
The No Flow Cut-off Timer sets the amount of time the dispenser/pump will allow a sale to
continue after the flow has stopped. The No Flow Cut-off Timer is terminated if the nozzle is
returned to its holster.
The range available is between 1 & 256 seconds. The default setting is 'n0000'(256
seconds).

SET-UP MODES C4000 SERVICE MANUAL COMPAC INDUSTRIES LIMITED
Page 10 31 May, 2004
Setting the No Flow Cut-Off Timer
Refer to section 3.1.1 page 8. While setting this value the price display will indicate ‘n’ and
the volume display will indicate ‘nXXXX’.
3.1.4. Display (Litres) Resolution
For standard dispenser/pumps, high flow dispenser/pumps & bulk metering, different
resolutions are often required:
Display Resolution Sr setting on k

NOTES:
1. As well as displaying the decimal point, a full colon will show on the display after 'power on', until the
first transaction is started (i.e. the display shows ‘:
0.0 ’until the first new transaction begins).
The display resolution does not affect the price display, which will always display to a
resolution of 0.01 dollars.
Setting the Display Resolution
Step ACTION RESULT
1Ensure that the nozzles are hung up Dispenser in idle state
2Press and release the ‘K’ Factor switch
continuously until the Litres resolution
is displayed
The price display indicates ‘Sr’ and
the Litres Resolution is displayed as
“0.00” (standard resolution on 5-digit
display)
3Press and hold the ‘K’ factor switch. The decimal point will begin to move.
4When the resolution (decimal point) is
correct, release the ‘K’ Factor switch.
NOTE: the C4000 will reset itself if the ‘K’
factor switch is left for more than 10 seconds.
3.1.5. Solenoid Delay
The Solenoid Delay was installed in the program to enable the "delay" between the
submersible pump operating and the dispenser solenoids operating to be controlled on initial
start-up. This setting should only be set on dispensers.
This setting should never be set more than 4-6 seconds. Its main purpose is to allow the leak
detector on the submersible pump to carry out its leak test.
The default setting is 'd0000’(i.e., no delay). All dispensers with a self-contained pump
should be left at the default setting.

COMPAC INDUSTRIES LIMITED C4000 SERVICE MANUAL SET-UP MODES
31 May, 2004 Page 11
Setting the Solenoid Delay
Refer to section 3.1.1 page 8. While setting this value, the price display will indicate ‘Sd’
and the volume display will indicate ‘dXXXX’
3.1.6. Pre-Set Cut-Off
Prior to the dispenser reaching its preset amount, the solenoids are switched to give a low
flowrate. The “preset cut-off” sets the amount (in litres), prior to the preset amount being
attained, at which the solenoids will switch to a low flowrate.
With the value set to 0.00, the default values are used. These are:
°LPG 0.75
°Oil 0.05
°Other products 0.32
The Preset Cutoff is calculated as follows:
[Price per Litre] X [over-run (displayed as a dollar value)] + default value as above
Example:
Price per Litre = $0.96
Dollar amount of fuel required = $20.00
After delivery price display shows: $20.01 ($0.01 is the over-run dollar value)
New preset = (0.96 x 0.01) + 0.32 (Other Products) = 0.3296
0.3296 rounded up = 0.33
New preset cutoff to be entered is 0.33.
Setting the Pre-Set Cut-Off
Refer to section 3.1.1 page 8. The Price display shows 'PCut' and the volume display
shows 'PCX.XX'. The range is from 0.01 to 9.99 litres.

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 AUTO
AUTHORISE mode of operation (used for wharf & aviation sites, 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.
°This can be adjusted to clients' requirements, between 1 and 256 seconds (refer
section 3.1.3 above)
•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).
NOTE: In AUTO AUTHORISE mode the nozzle input must be shorted out.
CNG Only: If digit 4 is set to zero, the solenoids stay on at the end of sequencing until the refuelling assembly
is returned to its holder, at which point all outputs turn off. With digit 4 is set to one, all the solenoids turn off
at the end of sequencing.
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.
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.
b X X X X
0 = Standard
1 = Auto-authorise mode. (If CNG then auto end)
0 = Sale goes through to Point of Sale as soon as the
preset is reached (Default)
1 = Nozzle has to be hung up before the sale goes
through to the Point of Sale.
2 = Comcard, Compin, and CWID/Key Basic Systems
0 = Price/litre is displayed as dollars/litre (Default NZ)
1 = Price/litre is displayed as cents/litre (Default AUS)
If CNG then this will display pressure in the
'Dollars' display during delivery.
0 = Stand alone operation
1 = Inhibit stand alone operation.

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.
NOTE: For the Bulk Meter Register, digit 3 must be 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: 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.
NOTE: 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 (See section 5.2 page
25). 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.
NOTE: 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).
NOTE: 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'
mode simply by turning them OFF for 1 minute minimum, then back ON.
However, for unattended situations (e.g. truckstops), 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.
Setting the ‘b’ settings
Refer to section 3.1.1 page 8. While setting the ‘b’ settings, the price display shows 'b' and
the volume display shows 'bXXXX'.
