Safety - C4000 Controller
Mechanical Safety
Safety - C4000 Controller
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.
Compac Industries Limited reserves the right to refuse to
accept any returned circuit boards if proper anti-static precautions have not

Electrical Commissioning
Electrical Commissioning C4000
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.
4.

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
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
Configuration Code
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'.

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
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'

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.

No Flow Cut-Off Timer
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 when no flow is detected. This timer applies at both
the beginning fill before filling commences and at the end of the fill after
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).

Solenoid Delay
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 selfcontained pump should be left at the default setting.
Setting the Solenoid Delay
Refer to C4000 Set-Up K Factor Switch Settings (see page 21). While

Pre-Set Cut-Off
Pre-Set Cut-Off
Prior to the dispenser reaching its preset amount, the solenoids are
switched to give a low flow rate. 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 flow rate.
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 Cut-off 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 cut-off to be entered is 0.33.
Setting the Pre-Set Cut-Off
Refer to C4000 Set-Up K Factor Switch Settings (see page 21) The Price
display shows 'PCut' and the volume display shows 'PCX.XX'. The range is
from 0.01 to 9.99 litres.

Specific Density (With a densometer)
This setting is only available for LPG dispensers with a densometer and
set-up for LPG with temperature compensation (configuration code =
7xx5x). This is not available in other modes.
For Bulkmeter modes (Sr=0) and LPG dispensers with
temperature compensation but without a densometer (configuration code =
5xx5x), the density must be set at the dispenser.
The specific density of the LPG is measured to allow the C4000 to
accurately convert the amount of LPG dispensed to the LPG dispensed @
15ºC. The specific density of the product is measured using the Compac
densometer and is corrected to specific density at 15ºC. It is always
displayed in units of kg/m3.

Press and release the Parameter switch seventeen (17) or more times,
without holding it depressed for long enough to change any digits, until
'SE9','XXX' appears. Hold the switch depressed until the correct
sequencing rate is displayed, then release.
The displayed sequencing rate is now selected and operation of the
dispenser will be affected immediately. The displays will reset after a ten
(10) second timeout.
Validating/Invalidating Cards Pins or Keys
This is only available on Comcard Basic, Compin Basic, or CWIDKey Basic
systems (i.e. 'b' setting digit 3 = 2.
1.
Ensure that the nozzle is hung up. Press the Parameter switch 16 or
more times without holding the switch depressed long enough for any
digits to change or for the system to enter the pump number setting
mode. The switch must be depressed for two seconds or longer for the
latter to occur. Card status information will then appear on the litre
display panel. The left of the display panel shows a 'Y' or 'n' where 'Y'
is Valid & 'n' is Invalid; the right of the panel shows the two-digit card,
pin, or key number.
2.
The desired card/pin/key number can be selected by changing each
digit using the usual press/hold/release method with the Parameter
switch. When the figure on the left side of the display panel is selected,
it can be changed from 'n' to 'Y' to 'n' etc. by holding the Parameter
switch depressed. Therefore, the respective card status can be
selected by releasing the switch when the desired card status symbol is
displayed.
To change multiple cards repeat the above process for the appropriate card
numbers. The display will return to normal operation after the Parameter
switch is not operated for ten (10) seconds.
On older systems Card 99 is the Service card and was
universally accepted by all Comcard card-readers.
Setting the Access Code
This is only available on Comcard or CWIDKey Basic systems (i.e. 'b'

Displaying and Printing Totals
General
To display litre and dollar totals for any single hose on a pump/dispenser,
make sure all nozzles are hung up. Then, for pumps/dispensers:

With Preset: Press either the Cancel or the Fill button, on the hoses'
respective Preset, five or more times and the totals will appear on the
displays.

Without Preset: Remove the nozzle from its holster and hold the nozzle
switch in for five seconds. Then press the nozzle switch rapidly five or
more times - ensuring that the switch 'clicks' each time. The five digit
whole dollar and litre totals will then be shown on the display for ten
seconds.
Scrolling Tote Option
This is only available on Comcard, Compin, and CWIDKey Basic systems
(i.e. 'b' setting digit 3 = 2)
To access this option the 'b' setting digit 1 must be set to one.
Pump/Dispenser totals are accessed as above, then after displaying the
pump/dispenser total for ten seconds the card/pin/key number and
card/pin/key total will appear. The display will flash for 10 seconds and then
go to the next card/pin/key. All cards/pins/keys with non-zero totals and all
valid cards/pins/keys will be 'scrolled'.
Using a Totals Only - Report
Printer
This is only available on Comcard, Compin, or CWIDKey Basic systems
(i.e. 'b' setting digit 3 = 2.)
Plug the two core cable from the printer into the four pin plug (Red Comms
- Pin 1, Black Comms - Pin 4) on the side of the pump/dispenser. Power up
the printer and make sure it is 'ON LINE'. Then depress the nozzle switch
five or more times - ensuring that the switch 'clicks' each time. The printout
will contain all cards/pins with non-zero totals and all valid cards/pins/keys.
Card/pin/key status is also displayed on this printout.
The printer may also be permanently wired to the C4000 comms. If the
printer is left with the power on and on-line, it will then act as an 'audit trail
printer'. It will then print out the card/pin/key number, litres dispensed and
the total in dollars, at the end of each fill.
All totals mentioned above are non-resettable totals (the only
way they can be cleared is by replacing the C4000 memory IC 'chip').
The displays are only capable of displaying five-digit whole litre totals
(maximum of 99999), but the C4000 memory stores seven digit whole litre
totals (maximum of 9999999.99) for printing
Receipt Printer
With Central Controller and Futra systems, it is possible to install a receipt
printer either at the pump/dispenser, or at the Central Controller.
The receipt printout includes the following information: Site Number, Pump

Printer Housed at the Pump/Dispenser (Card King)
This is only permissible in 'Type B' fuel pumps/dispensers (as defined by
AS2229-1) or in pumps/dispensers used in applications where less
stringent requirements are set. This is because the printer is not an
intrinsically safe device and must have access to the pump/dispenser
exterior for the 'printer paper slot'.
The printer receives the data for printing and cutter operation from the
C4000 microprocessor PCB, via an interface PCB (CI125) which also
provides the printer with a 12V power supply. The interface PCB provides
'opto-isolation' between the C4000 intrinsically safe circuitry and the
'unsafe' printer circuitry, for the printer driver signal.
This Receipt Printer option is only available for C4000 microprocessors
controlling one hose pumps/dispensers, or for C4000s which are set-up in
'True Multi' configuration. A PIN pad must also be connected to the C4000
and the third digit of the Configuration Code must be set to '1' or '3'

On a pump/dispenser set-up with a receipt printer, a receipt is obtained
as follows:
1.
Authorise the transaction as for a normal fill until the PIN pad
display reads “REQUIRE RECEIPT YES OR NO”
2.
Press
3.
The display will read “TAKE FUEL”
'YES'
Continue the fill as per normal and at the completion of the fill, a receipt will
print automatically.”

If the nozzle is still in holster:
1.
Pin pad reads:
“LOAD PRESET”
2.
Press:
“ENTER”
If the nozzle is lifted:

Pin pad reads:
“TAKE FUEL”
If the Receipt Printer is not operational (e.g. out of paper),
then when the PIN pad displays: “PASS CARD” it will also display:
“NO RECEIPT”
Electrical Connection
The data cabling for the printer connects to the C4000 intrinsically safe
terminals at connector J14. The other end of these wires connects to
connector CON5 on the Interface PCB (CI125).
The 220-240V supply connection on the Interface PCB is at connector
CON1.
Power and data connections to the printer and cutter are from CON2 &
CON3 on the Interface PCB.
Receipt Printer Connected to the Central Controller
Where a Central Controller is installed on site, it is possible to connect a
Receipt Printer to the Central Controller Comms Port 3 to obtain printouts.
Two operational options can be configured at the pump/dispenser C4000
when the Receipt Printer is connected like this:
1.
Compac Industries Ltd.
If a Receipt Printer is connected to the Controller and left „ON LINE‟,
then by setting the third digit of the Configuration Code to '0' or '2' (for
standard or Secure PIN pad operation respectively), a receipt will be
printed after each transaction. This should be the set-up chosen when
a receipt is always required or when the pump/dispenser does not have
Page 42
www.compac.co.nz
Set-up Modes
Basic Systems (Comcard Compin & CWIDKey)
a PIN-pad installed.
2.
If the pump/dispenser has a PIN pad connected, then it can be
configured to display a receipt prompt as part of the transaction
authorisation process. This prompt would be the same as for a
pump/dispenser with a Receipt Printer connected to the C4000
(detailed on the previous page). To select this option the third digit of
the Configuration Code for the C4000 should be set to '4' or '5',
depending upon whether a standard or Secure PIN pad is installed on
the pump/dispenser.
Electrical connection of the Receipt Printer in this mode is covered in the
Central Controller Service Manual.
Basic Systems (Comcard Compin & CWIDKey)
For these systems to operate the 'b' setting digit 3 must be set to two. Refer
'b' Settings (see page 18). In this mode of operation the 'C4000 Head'
operates as a totally self-contained system operating independently of the
central controller. The C4000 'Comms' circuitry, which is usually used for
communicating with a controller, is now used to run an audit trail and/or
receipt printer (Refer Printer Set-up (see page 40)). These systems can
have a maximum of 99 cards/pins/keys.
Comcard Basic
The Comcard Basic system uses magstrip cards to initiate a transaction.
These cards are encoded with an access number and a card number.
There can be only one access number per pump and the card numbers
must be in the range of 01 to 99.
In older Comcard basic systems, card number 99 was
reserved for servicing.
All Comcard Basic systems will have a card reader attached to the front or
side of the pump/dispenser.
Usually the card number is printed or embossed on the card. If this is not
the case the card can be identified in the same manner as the CWIDKey
identification procedure.
Compin Basic
The Compin Basic system simply uses a two digit PIN number to initiate a
transaction. This operates in the same manner as the Comcard Basic
system except that digit 4 of the configuration code (refer Setting the
Configuration Code (see page 16) ) must be set to two (2). Also there is no
access number required. The PIN number acts as the card number and all
of the same totals are available.
CWIDKey Basic
The CWIDKey Basic system uses a CWID (Compac wireless Identifier) key
to initiate a transaction. These systems have a CWID aerial placed at the
nozzle or on the pump/dispenser.
Where the aerial is placed at the nozzle, the CWID tags must be mounted
in close proximity to the filling spout. If the aerial is on the dispenser the
customer must hold the CWID tag close to the reader panel on the
dispenser. The CWID tags are a small (approx. 32mm x 5mm diameter)
sealed tag. They do not require batteries.
The CWIDKey Basic system operates in the same manner as the Comcard
Basic system except that digit 3 of the configuration code (refer Setting the
Configuration Code (see page 16) ) must be set to six (6). The CWID tags

When a valid key is presented to the dispenser the display will alternately
flash the key totals then the key number, until the nozzle is lifted. The key
number is displayed as "c xx" where xx is the keynumber. The access
number is never displayed.
If an invalid key with the correct access code is presented to the dispenser
the display will show "----" for one second then the key number for one
second.
If a key with an incorrect access code is presented to the dispenser then
the display will only show "----" for two seconds.

is to connect to a Gilbarco Consul. The Comms dipswitch settings (See
Figure 7 & Figure 9) must be set with switches 1& 3 OFF and switches 2 &
4 ON.
The Gilbarco interface board plugs onto the IS Power supply PCB in the
Flameproof box. The IS Cable must be setup to connect to the Gilbarco

Air Detector Cut-out Switch
The Air detector cut-out switch is required on any Bennett pump pumping
diesel or any Bennett pump pumping any product at more than 55 litres per
minute. This switch is a 'normally open' pressure-activated switch, which
closes when the pressure of the air venting from the pumping unit exceeds
a preset level. The closing of this switch disables the C4000's outputs,
ending the transaction in progress. The pump can be re-authorised and
another transaction can take place immediately after the pump stops,
without the need to de-power and re-power the electronics.

The nozzle switch leads plug in between 'NSWx' and 'GND' (see Figure 10
above). When the nozzle is lifted, the nozzles switch closes and the C4000
initiates a transaction.
Diagnostic LED will flash rapidly when any nozzle is lifted
regardless of hose configuration.
Sump Switch
The Sump Switch is a float switch located in a sump at the bottom of the
dispenser. If the dispenser pipe work leaks, then the tray fills with product,
thereby activating the switch.
If the switch closes, then the dispenser stops and the litres display reads
"SunP".
The Sump Switch is wired into the SUMP and GNS terminals on the J12
connector (see Figure 10). If there is more than one head in the dispenser
(e.g. MHD6), then the sump switch is to be connected to both heads.
Ensure that the SUMP terminals are joined and the GNS terminals are
joined.
DO NOT connect the GNS terminal on one head to the
SUMP terminal on the other.

track on the magnetic strip of the card which will be read.
Compac Systems will be either a TK1 or a TK2 type, and will
never be used both together. This is because information is coded, and
therefore gathered, from either the first track or the second track of the

Tuning the Aerial
Whenever the CWID PCB is changed, the aerial will need to be tuned. For
locations of the connectors, refer to the picture in CWID Interface Board
Replacement.
1.
Connect a Multimeter (set to Volts) to CON8.
2.
Place a shorting link across pins 2 & 3 of CON4. The poll LED will flash
slower, indicating "Tuning Mode"
3.
Using the dipswitches (SW1), adjust the capacitance to obtain the
maximum voltage at CON8. Each dipswitch adds a capacitor to the
tuned circuit. The DIP switches 1 to 5 are primary capacitors while 6 to
8 are fine tuning capacitors.
4.
Use the following technique:
5.
Turn on Switch 1 and measure voltage, turn on switch 8 and see if
voltage rises or falls. If it rises, turn off 8 and turn on switch 2.
6.
Continue this procedure for switches 3,4 and 5 until you get a voltage
drop.
7.
If the voltage drop occurs at switch 2,3,4 or 5 then return to the
previous switch and add switches 6,7 and 8 until the voltage drops.
When the drop occurs, revert to the previous switch.
8.
If there is no voltage drop as switches 6, 7 and 8 are added, compare
this voltage to the voltage achieved at the next primary switch with 6, 7
and 8 turned off.
9.
If you can't get a voltage drop when the fine tuning switches are used,
use the chart below to calculate a capacitance figure between the
switch combination achieved above. For example:If 1+2+6+7+8 (7.3
nF) obtains a higher voltage than 1+2+3 (8.33nF) then try 1+2+5 (7.33
nF) if the voltage reading is higher than the two previous combinations,
switch on 8 then 7 then 6 until you get a drop. If no drop is measured
then try 1+2+4(7.66 nF). Keep working with combinations until you get
the voltage drop when one of the fine tuning switches is added or you
have run out of combinations. Always use the setting that achieves the
highest voltage.
10. If the voltage drop occurs at step 5, turn off switch 1 and turn on
switches 2,3,4 and 5 then test for voltage drop with switch 8. If voltage
drops then turn off switch 5, measure voltage and test again with switch
8. Continue with combinations until a voltage drop occurs when one of
the fine tuning capacitors is switched on.
11. Though the CWID aerial can work at lower voltages, the voltage
reading should be above 28 Volts.
12. Remove the shorting link fitted at 2 above.
13. Test the operation with a valid CWID key.

Encoder
The rotary encoder translates meter turns into electrical pulses. Each turn
of the Bennett meter equals approximately 0.5 litre (eight turns = one US
gallon). The encoder converts this to 150 pulses so that each pulse
corresponds to approximately to 3ml.
Exact values are:
One rotation
=
0.47 litre
150 pulses
=
0.47 litre
One pulse
=
3.1 ml
When the C4000 'head' is used for other meters this ratio can vary, e.g.
from 0.5 litres / turn to as high as 10 litres / turn.
The encoder will rotate up to 600 rpm before 'tripping' an „Er 7‟ message. If
the encoder is disconnected, the C4000 will not start the pump and an „Er 9‟
message will be displayed.
The encoder connects to the C4000 via a six-core (only five cores used)
data cable. The five cores used are:
Orange or White
-
5V terminal
Yellow or Black
-
0V terminal
Brown
-
B0 terminal
Blue
-
B1 terminal
Red
-
B2 terminal
Where B0, B1 & B2 are the three opto-senser connections
To reverse the rotation of the encoder sensing, the B0 & B2 wires should
be reversed. The error message for reverse rotation is „Er 8‟.

High/Low Flow Switch
A High Flow/Low Flow option is available on high flow dispensers/pumps. The
two-position switch is located on the side of the dispenser/pump by the nozzle
holster.
In the high flow position, the full flow rate of the pump/dispenser will be
available at the nozzle. In the low flow position approximately 40 to 70 lpm will
be available depending upon the application.
High/Low Flow Operation Methods
Method 1
When the pump is fitted with a hi-lo flow switch, it enables the user to be
able to select two different flow rates.
The switch has two positions: UP for high flow, and DOWN for low flow
(80litres/m). The two termination screws are located at the top.
When the hi-lo switch is used in the "HI" position, it energises outputs on the
C4000 to operate motors #1 and #2 (with a one-second interval before
motor #2 starts), which in turn operates their associated pump.
When the hi-lo switch is in the "LOW" position, only motor #1, and its
associated pump operates.
The changing of the Flow Selector switch position during a
transaction has an immediate effect on 'Pump 2's' operation. I.e. The motor
for 'Pump 2' can be turned off and on during a transaction.
Method 2
This is used in dispensers supplied by submersible pumps and in pumping
units with a preset operation.
Two solenoids valves 38mm NB & 18mm NB are installed in parallel after
the meter. For high flow, both solenoids valves are open. For low flow, only
the 18mm NB solenoid valve is open.
Method 3 - 3 Phase Pump (M200P)
This is used in pumping units without preset operation.
One 18mmNB-solenoid valve is piped as a 'by-pass' across the pumping
unit. When open this allows some of the product being pumped to return to
the inlet (low-pressure) side of the pump and hence reduces the flow rate
through the nozzle.
Electrical Connections
To control the solenoids in high/low flow operation, the two core cable from
the flow selector switch connects to 'FLOWx' or 'FLOWx' terminals on the
C4000 Microprocessor PCB connector J12 (see Figure 10). 'FLOW0' is
used for side 'A' and in the case of a dual with high/low flow on both sides,
then side B's flow selector switch connects to the 'FLOW1' terminal. The
switches are to be connected between the 'FLOWx' terminal and 'GND'.
Closing the contacts on the flow selector switch of Side 'A' ('FLOW0')
causes the 'T7' output terminal to energise. For Side B the 'T9' output
terminal is energised. In Method 1 the 38mmNB Solenoid is wired to the
'T7' output and the flow-selector switch is 'closed' in the high flow position.
In Method 2 the 18mmNB Solenoid is wired to the 'T7' output and the flowselector switch is 'closed' in the low flow position.

Totalisers
Electromechanical Totalisers
Only approved Compac totalisers are to be used. Some totalisers have a
+ve and a -ve terminal.
Electronic Totals
As well as having electromechanical totalisers for litres dispensed from the
pump, each C4000 stores in its memory a five-digit litres total of fuel
dispensed from each hose. Both these totals are non-resettable.
These totals can be displayed by pressing the CANCEL or FILL buttons on
the preset keypad, of the meter/hose in question, five times in quick
succession.
The totals will then appear on the pump displays, on the LITRES and
DOLLARS display, for ten seconds before the display resets.
In the absence of a preset keypad, remove the nozzle from the nozzle
holder. Hold the nozzle switch down for at least three seconds and then tap
it down five times in quick succession. The totals will appear as described
above.

Software Upgrade Procedure
Displays: Litres only, Retail, Multi-price & Preset
Software Upgrade Procedure
This is the software upgrade procedure to be followed for all bulk meter
registers and all pumps with a C4000 other than those with FUTRA
software.
1.
Ensure, before working on the pump, that anti-static precautions are
taken (i.e. wearing of wristband with earth strap).
2.
Gain access to C4000 Processor Board and record all set-up data by
accessing the configuration (K-Factor) switch and the parameter
switch, this includes recording the comms dipswitch settings. Data setup to include:
3.
K factor 'F '
4.
No flow delay 'n'
5.
Pre-set cut-off margin 'PCut'
6.
Density Factor 'dSF' (CNG only)

Specific density 'SPG' (LPG only) Flow rate 'FLO' 'r' (some
bulkmeters only)

Temperature 'E' (bulk meter or LPG only)

L Cut 'L' or 'LCUT' (bulkmeter only)

H Cut 'H' or 'HCUT' (bulkmeter only)

F Cut 'F' or 'FCUT' (bulkmeteronly)

Set resolution 'Sr'

Configuration 'C '

'b' Settings

Price 'Pr' or 'P'

Density 'd' (bulkmeters only)

Pump number 'Pn'

Sequencing Rate 'SE9' (CNG only)

Access code 'A' (comcard or CWIDKey Basic dispensers only)
7.
Electronic and mechanical totals should also be recorded.
8.
In the case of 'Comcard Basic', 'Compin' (Mining), or 'CWIDKey Basic'
systems, a printout of card/pin/key totals must be obtained before
changing software. This printout will also give card/pin/key validation
status. If no printer is available, use Scrolling Tote option (refer
Totalisers (see page 56)).
9.
The above steps are taken to safeguard against software
incompatibility causing loss of information.
10. Turn off power.
11. Remove software EPROM (removable chip labelled C4000 PXX or XXX-XX:XX.X) using an EPROM extractor. (See Figure 1 for the location
of the EPROM.)
12. Plug in new software EPROM, being careful that the dimple is at the
correct end of the socket. (i.e. software chip dimple to base dimple).
Also that all the legs are correctly located in the socket (see diagram
below).
13. Turn on power.
14. Check that the data recorded in Steps 2 and 4 is still present, if not reenter.
15. Check the electronic totals, if not as before then give 'before' and 'after'
totals to relevant people on site.
16. Ensure that the status of cards/pins/keys, on 'Comcard', 'Compin', or
CWIDKey systems, are as before. If they are different in any way,
ensure that the relevant people on site receive 'before' and 'after'

printouts of card/pin/key totals.
17. Test pump operation.
When replacing Integrated Circuit chips (refer to Figure 19
below), ensure that the notch is facing in the direction of the IC board
socket (the notch is the end that we refer to as the "front").
When inserting the IC chip, the rear pin (of the IC chip) must be plugged
into the rear pin socket of the IC board socket. Any spare pin sockets
should be in front.
Failure to correctly insert the IC chips or adhere to the above guidelines
specified herein will result in a loss of memory data.

Solid State Relays (Triacs)
General
The solid state relay, as the name implies, is a solid state switch, controlled
by the C4000. These solid-state switches control the C4000 220-240volt
outputs.

Figure 7. Location of Solid State Relays (Triacs) and Comms DIP Switches (SW3)
There are 10 separate solid state relays (small triacs) on the C4000 PCB.
The output terminals for these triacs is T1 to T10. Their function varies
depending on what the C4000 'head' is controlling. Below are tables
showing the use of these outputs for various applications.
The T1 and the T4 outputs can be used to drive a high current triac whose
output will be on the LOAD1 and LOAD2 terminals respectively. Each of
these outputs (T1 and T4) has an associated switch (SW1 and SW2
respectively) which must be used to select the type of output required (refer
Figure 8).
The T7 output cannot drive a high current triac directly but may be looped to
T1 or T4 of another C4000. If it is looped then SW4 must be in the mid
position. Position 1 of SW4 should never need to be used.
The power for the triac outputs can be supplied from a separate mains
supply (Separate from the supply for the microprocessor). There are two
blocks of connectors for the phase connection (refer Figure 7). The block of
six connectors supplies the microprocessor and the block of four connectors
supplies the triac outputs. These two blocks of connectors are normally
looped together in the factory.

High Current Triac Option
Where high current (40A) outputs are required (i.e. driving the pump motor
directly) high current triacs are fitted to the power supply PCB. If a high
current triac is installed for T1 and/or T4 then its respective snubber switch
(SW1 & SW2 respectively) needs to be switched to position 1 (Refer Figure
