Safety
Safety
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.
Pre-Installation Check
Once the unit 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
Comtank units are designed to be attached to existing pumps and dispensers. Before installing a
Comtank, a pump or dispenser must be already installed and working correctly. To install the
relevant pump or dispenser, refer to their respective installation manuals, which will have been
provided with the unit, or are otherwise available on the Compac website in the Resources
section:
https://www.compac.biz/resources/c/48#listingResources
When installing pumps and dispensers, the setup section can be ignored as set up can be done
from the Comtank unit once connected.
Connecting the Comtank
Once the pump or dispenser has been installed, mount the Comtank as directed in the Footprints
section (see page 2.) The Comtank can be connected to the pump/dispenser with a supplied 5
metre cable that runs between the PIN pad board of the Comtank and the K-Factor board of the
pump/dispenser. Connect the cable to the bus in port on the PIN pad board and the bus out cable
on the K-Factor board as shown:
K-Factor board on pump/dispenser
PIN Pad board on Comtank

6.
Installation
Installing the Sim Card
When installing the Comtank, the supplied sim card must be installed into the modem to access
Compac Onsite. The modem will need to be removed to install this. The modem is generally
housed in a plastic enclosure on the back left side of the pump/dispenser unit.
As shown, there is a small plastic panel on the back of the modem. This can be removed. The
supplied sim card should be installed under this panel. The panel and modem should then be
replaced.
Configuring Slave Displays
Slave displays, which are commonly present on the back of units or on remote displays, can be
configured to display side A, side B, a clone of the main display, or can be disabled. To configure
the slave display, the address must be set with the dipswitches on the slave circuit board. This
address must then be entered into the unit software with the corresponding setting (disabled,
clone, side A or side B.)
The address of the slave display must be set with the dipswitches on the slave board. Set the
address of the slave display as follows:
Switch 3
Switch 2
Address
0
0
1
1
0
2
0
1
3
1
1
4
NOTE: Switch 1 is currently unused.
The address then corresponds to a digit in the Parameter d setting. To change this setting, depress
the Parameter switch until the d setting menu appears:
Back of modem
Remove this panel

7.
Installation
Each digit corresponds to the address set on the slave display. In this example, the first digit 0
corresponds to the slave display set to address 1. The second digit 3corresponds to the slave
display set to address 2, and so on. Each display can be set to 0-3, depending on the desired
setting:
•0 –Disabled
•1 –Side A
•2 –Side B
•3 –Clone
Therefore, in this example, the slave display set to address 2 is showing a clone of the main
display. The slave display set to address 3 is showing side B. Slave displays set to address 1
and address 4 are disabled.

Software
Software
This section details what options are available for the unit and what each setting means. Some
settings may not be available for each specific unit.
System
Card Records
Before cards can be added, card records need to be set up from the unit. When setting up card
records, a PAN length, BIN range, and access number can be specified. These are encoded onto
the card and can be used to restrict access to the pumps. PAN length is the number of digits
that make up the BIN number and card number. The BIN range gives access to a range of cards
that have similar BIN numbers. BIN numbers are always 6 digits long. To make this into a BIN
range, two numbers must be added. For example, if a card had the following card number:
7824331000132017
The card is 16 digits long, therefore the PAN length is 16.
The BIN number is 782433. To allow all cards with the same BIN number access:
BIN low should be set to 78243300.
BIN high should be set to 78243399.
This would allow all cards with a BIN number of 782433 access. The Access number is used to
further restrict cards. This is a 5-digit number and will be encoded onto the cards. 0 should be
entered into the Access field if the card does not have an access number. Once the card records
are set up, specific cards can be entered into the system using PAN numbers.
If a card is hotlisted, it will be accepted even if the card PAN number has not been entered.
Otherwise, the card’s individual PAN number will have to be entered as a card. Prompts are an
optional setting which may be chosen when setting card records. The prompts that are selected
when entering a card will appear when that card is swiped; for example, if odometer is selected,
the card holder will have to enter an odometer number to access the fuel pump. Cards can be
enabled or disabled.
Passcode
For security, the unit has a passcode. This can be used to access settings from the unit. For
extra security, if the settings are accessed with the passcode, some options are not able to be
changed, such as the K-Factor setting. These must be accessed by pressing the K-Factor
switch.
The unit supports three different authorisation modes: PIN, HID or Cardreader. The system can
be set up from either CompacOnsite or from the unit itself.
Pumps
The Comtank supports two configurations, single and dual, enabling two pumps to be used
simultaneously if one card is used. These pumps are assigned a side so that they may be
individually customised. Each side must be numbered between 1-99.

9.
Software
NOTE: Entering a pump number 0 will disable the pump.
Individual settings for each pump include the fuel product used, which has a name and product
code, and the meter used at each pump. The unit supports encoder meters (max frequency
3.5Khz) or V50 meters. The K-Factor, used to calibrate fuel flow, can also be set for each pump.
The state of the pumps can be either operational or locked, which may be desired if the pump is
not operating normally. Pumps have two solenoids for product flow. If the solenoids are
unavailable, the pump preset should also be unavailable. Solenoid delay, the amount of time it
takes the solenoids to turn on after lifting the nozzle, can be customised for each side. Auto
authorisation can be enabled for a pump, allowing the pump to be authorised without lifting up
the nozzle.
Preset Cut-off and Rounding
Preset cut off is used to deliver an accurate amount of fuel. When dispensing fuel, two solenoids
are used for fuel flow. When the dispensed amount of product reaches the preset cut off, one
solenoid is turned off to slow delivery rate and dispense an accurate volume of product.
A two-digit number can be assigned to determine the preset rounding in litres. The first digit
determines how the preset is rounded down, and the second digit determines how the preset is
rounded up. For example, if Preset Rounding is set to 89 and the preset is 40;
40.08 is within .08 of 40 and would therefore be rounded down to 40.
39.91 is within .09 of 40 and would therefore be rounded up to 40.
Flow Range
A flow range is needed for each pump to dispense an accurate amount of product. If too much
or too little fuel is dispensed, the meter cannot accurately measure the dispensed fuel and
therefore should cut off and display an end of sale message. The flow range will vary for
different products. Flow low should be the lower value of the flow range, while Flow high is the
highest possible flow.
NOTE: Flow range is optional. The default value is 0.
A flow timeout can be set, which cuts off the motor after the set amount of time. The default is
000, which is 20 seconds.
Unit Price and End of Sale
The unit price is the price per litre of fuel dispensed. For this unit, it is displayed in the Card
Totals window.
End of sale indicators show why the motor stopped during the last sale.
Cards and Card Users
Card numbers must be added for a card to be valid. Card or HID numbers can be added. These
numbers should correlate to the earlier card setup done in the system section.

10.
Software
Cards can also have User IDs, which are optional prompts for cards. If a User ID is asked for the
customer dispensing fuel will have to enter a valid User ID. If a user ID is not required, and
instead the retailer wants a different prompt (such as Fleet number) user ID can be configured to
ask for different prompts.
Meters
The unit supports encoder or V50 Modbus meters. The encoder meters can be single, dual or
triple channel. Single channel encoders measure the fuel dispensed. Dual channel encoders do
this as well as determine the rotation of the meter (and therefore the direction of fuel flow).
Triple channel meters can determine if the meter is correctly connected and functioning.
K-Factor
The K-Factor is used to calibrate product flow. It is a ratio of litres dispensed per revolution of
the meter. The K-Factor may need to be calibrated after periods of time. To calibrate the pump,
dispense fuel into a certified measuring container and compare the display value with the one
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.
𝑁𝑒𝑤 𝐾 𝐹𝑎𝑐𝑡𝑜𝑟 = 𝐸𝑥𝑖𝑠𝑡𝑖𝑛𝑔 𝐾 𝐹𝑎𝑐𝑡𝑜𝑟 ∗ 𝐷𝑖𝑠𝑝𝑒𝑛𝑠𝑒𝑑 𝐴𝑚𝑜𝑢𝑛𝑡
𝐷𝑖𝑠𝑝𝑙𝑎𝑦𝑒𝑑 𝐴𝑚𝑜𝑢𝑛𝑡
= 𝐸𝑥𝑖𝑠𝑡𝑖𝑛𝑔 𝐾 𝐹𝑎𝑐𝑡𝑜𝑟 ∗ 20
10
= 𝐸𝑥𝑖𝑠𝑡𝑖𝑛𝑔 𝐾 𝐹𝑎𝑐𝑡𝑜𝑟 ∗ 2
Unique ID is for a V50 meter only.
Once the K-Factor has been determined, refer to Setup Instructions (see page 11) for
instructions on how the change the K-Factor,
Tanks
Tanks can be set up with their corresponding product, number and capacity.
Tank Gauging
Tank gauging is used to determine how much fuel is left in a tank. The Comtank supports four
tank gauges; Veeder-Root, Fafnir, Vega and Virtual. To accurately gauge the volume of fuel, the
tank number, safe fill level and capacity are required. These depend on the tanks onsite. If a
Vega electronic dipstick is used, please note that more information will be required; the position
of the probe in the tank is needed. A Tank Strapping table ID will be required to calculate
volume. A Vega electronic dipstick may also be connected differently; the gauge channel may
change depending on the connection to the Comms board.

11.
