Introduction
The Compac DCA is designed as an authorisation station for controlling the
operation of fuel pumping systems. It is compatible with most common fuel
pumps and can be easily customised to accept a variety of authorisation
methods and provide detailed transaction reporting. The main features
include:
Stand alone unit for unattended refuelling
Stainless steel construction
Tactile keypad
Robust, reliable receipt printer
Authorisation options include: Card, Pin, HID tag, iTrack, Roseman or
Compac Wireless ID (CWID) tag or nozzle loop
Most major oil, gas company and third party cards accepted
Data retrieval and client management by CompacOnline software or
USB key
Reporting of tank gauge readings via CompacOnline (option)
Communication via ADSL modem, 3G wireless, LAN cable or wireless
LAN.
Ability to authorise high volume pumping systems
There are two basic models of Driveway Card Acceptor.
Model 1 is known as a Driveway Card Acceptor [DCA]
A Driveway Card Acceptor is designed to be used on an unattended site
where the fuel pumps are authorised and controlled totally by the DCA.
A DCA has the site controller circuit board [Communicator Controller]
included inside the unit.
A DCA can be configured with the appropriate hardware to communicate to
and control Compac, PEC protocol and selected Gilbarco and Email
protocol pumps.
Model 2 is known as a Retail Authorisation Station [RAS]
A RAS is designed to be used on a retail site where cash and card sales
can take place during attended hours and card sales only can take place
after hours. A RAS is connected to a Compac Communicator Controller on
the pump communication loop. The Communicator Controller is normally
located in a nearby office. You can have multiple Retail Authorisation
Stations on one site connected to the controller.
For clarity, all units are referred to as DCA units unless it
contains a feature specific to a RAS unit.

Introduction
Compac Industries Ltd.

www.compac.co.nz
Options
The DCA is a very versatile unit and can be equipped for many different
functions depending on the customer's requirements.
Driveway Card Acceptor
The Compac Driveway Card Acceptor [DCA] is a standalone unit designed
for unattended refuelling. The DCA can accept multiple card bases
simultaneously including all major Oil Company, Gas Company and third
party cards. It can authorise and control Compac, PEC, Gilbarco and Email
Pumps with the appropriate hardware. It is NSC [Weights and Measures
Australia] approved.
The DCA uses a DS1250 memory chip which has the ability to change the
partition on the memory to make more space for more card numbers in
exchange for a reduction in transaction memory.
Standard partition
5,500 Transactions
5,000 Cards
Optional partition
4,000 Transactions
22,000 Cards
These figures are approximate depending on the fields
required.
Card numbers can be stored in two different ways: In limited validation
mode, only the card numbers stored in the DCA can be used. In extended
validation mode all valid ISO or mapped cards will be accepted apart from
the "Hot Card" numbers that are stored in the DCA.
To download and manage transactions, the DCA has the following
interfaces available:
USB key
CompacOnline
The following interfaces are no longer sold:
Dial-up modem interface - (download via Netbase) - supported
Printer interface (download to audit trail printer) - no longer supported
PC interface - (downloads direct to a PC) - no longer supported
Standard Operation for a DCA
The driver goes to the DCA and Swipes their Card.
If the card is valid, the DCA display will request PIN entry [optional] and
Odometer entry [optional].
The DCA display requests the driver to select which pump they wish to
refuel from.
The DCA display advises the driver to take fuel.
After the transaction, if the driver requires a receipt he/she goes back to the
DCA and re-swipes their card. Select YES to print receipt. (If NO is
pressed, a new transaction will be started.)
To access DCA data there are the
following options:
1. Print out reports on the Audit Trail Printer
2. Download the data directly to a PC running NETBASE
3. Download the data VIA MODEM to a PC running NETBASE
4. Display real time information and download data using CompacOnline
software via a 3G or ADSL modem.
5. Download data to a USB stick

Introduction

Components
The DCA consists of the following components:
Galvanised post base that is secured to the ground.
Post to support the DCA. This post is manufactured from stainless steel
and is powder coated white. It has a removable back plate to allow the
DCA housing to be easily bolted on and allow access to the electrical wiring
to and from the cabinet.
DCA Housing. The housing is manufactured from stainless steel and is
powder coated white. The card-reader, printer and PINpad keypad/display
are fitted into the DCA housing door. A Communicator Controller circuit
board is located inside.
A heater and thermostat are provided for climates where the temperature
may fall below 10 degreesC to prevent moisture forming inside the cabinet.
Other components such as a modem, Gilbarco or Email Pump Interface,
and Pump comms booster circuit may be installed.
The DCA housing door is weather sealed and secured by two locks.
The Card Reader can be track 1 or 2. We do not support a reader reading
and processing track 1 and 2 simultaneously.
From 2012 onwards DCAs are fitted with a tactile key pad. Previous
versions have a capacitance non-contact type.
Receipt printers are fitted to units where a printed receipt is required.
Printer
DCAs are fitted with two types of receipt printer. Prior to June 2012, DCAs
are fitted with a guillotine style printer with receipts dispensed into a
container accessed via a sliding door. From June 2012 onwards DCAs are
fitted with a tear-off style printer with receipts dispensed via a chute.
The two styles of printer use different sized paper rolls that
are not interchangeable.
For guillotine style printers order: F-BA-PRTER-CK-RL
For tear-off style printers order: F-BA-PRT-TG60X80
Use only Compac supplied water-resistant thermal paper.

Litres Total
From July 2012, Compac dispensers that are connected to Compac fuel
management systems (FMS) that do not have a customer receipt printer,
are fitted with an additional display line labelled "Litres Total". This display
shows the total amount of fuel dispensed from the site to the authorisation
card or ID tag. The total is shown as litres to two decimal places.
Use
When a PIN number is entered, authorisation card swiped or an ID tag
detected by the fuel management system, the selected dispenser will
display the current total litres dispensed to the card (or ID tag) by the site
FMS.
The total will update as fuel is dispensed. When the transaction has been
completed, the new total is stored in the fuel management system. The
next time the card is swiped or ID tag detected by the FMS, the current
Litres Total will display on any of Litres Total capable dispensers on the
site.
The displayed total only relates to the amount of fuel
dispensed to the individual card or tag on that particular site.
Standalone
If the dispenser is set to standalone mode, the authorisation unit is
bypassed and no totals are recorded against the card or ID tag.
Software
The dispensers with Litres Total capability run software version 29255.
Fuel management systems manufactured after July 2012 have Litres Total
capability. Systems manufactured earlier than this require a software
upgrade.

Installation Guidelines
Compac Industries Ltd.
Page 15
www.compac.co.nz
Installation Guidelines
You must be properly qualified, trained and authorised to install this
unit. Ensure you are qualified to perform each of the operations described.
Location
The Compac DCA is NOT suitable for mounting in a hazardous area.
Please consult the site's zone drawings to find the exact positions of the hazardous
areas for each particular site.
For adequately ventilated fuel dispensing sites (not including CNG/NGV), in most
cases the following will apply:
The unit is not designed to be constantly exposed to the elements. A canopy or
shelter should be installed to protect it.
The card reader and PIN pad should face away from the prevailing wind
especially in dusty or wet areas.
In areas experiencing extremes of weather (heat, cold, wind, rain, salt spray
etc.) consideration should be given to installing additional shelter.
The DCA location or protection should be such as to minimise the possibility of
damage from vehicles, trailers, boats, or the like.
On heavy vehicle sites, mounting the unit on a raised pad and/or installing
bollards to help protect from damage.
If mounting on a post, the base needs to be attached to a smooth, level surface
of sufficient strength to securely hold the retaining bolts or fasteners.
The DCA should be placed at least 8 metres from any above ground flammable
liquid storage or handling facility other than a dispenser.
The DCA should be placed at least 0.5 metres from any flammable liquid fuel
dispensers and 1.5 metres from any LPG dispensers.
The DCA should be mounted so that the base of the cabinet is at least
1.2 metres above the ground. If mounted on the post supplied by Compac it will
be 1.2 metres high.
Whenever running a cable through the post into the base of the cabinet always
ensure that the cable entry into the cabinet uses a vapour tight gland.
If the DCA post is within 4 metres of a dispenser or within 1 metre of the end of
any fuel dispenser hose, then the entire interior of the post may be considered a
hazardous area. Any cables running through, or electrical equipment mounted
in the post should be suitable for that hazardous area (refer AS/NZS 2381).
Generally the area below the DCA may be a hazardous area and therefore
some appropriate signage may be required e.g. no smoking.
Lighting should be provided during the hours of operation. Lighting should be
sufficient to provide safe working conditions that include, but are not limited to,
clear visibility of all markings on packages, signs, instruments and other
necessary items.
A minimum value of 50 lux is recommended.
These requirements do not apply to any specific site but are merely
recommendations that will apply in most cases. The owner/installer must ensure that
the installation complies with AS/NZS 3000, AS 1940, and any other applicable
regulations.

Installation Guidelines
Compac Industries Ltd.
Page 16
www.compac.co.nz
Guidelines for Mounting the
DCA on a post
If a post is part of the installation:
Make sure you have all the appropriate wiring (power, pump comms, modem, printer
etc) led to the location where you are mounting the DCA.
The post assembly should include the following parts:
Galvanised base
DCA post
Back panel for DCA post
Flange with 4 studs
Nuts, washers and spring washers for studs
Button head cap screws for back plate
Level and securely mount the galvanized post base using appropriate fastenings for
the surface it is being mounted on. The mounting plate has 4 x 19 mm holes for
fastenings.
Due to the different surfaces that the DCA can be mounted on,
Compac does not supply fastenings for the base plate. Installers should use
fastenings suitable for the individual situation.
Attach the post to the base with the 4 coach bolts provided.
Feed all wires through the base plate
Place the DCA cabinet on top of the post and line up the mounting holes in the
cabinet to the holes in the base.
Insert the flange into the post, push the studs through the holes and fasten the
cabinet to the post using the 4 washers, spring washers and nuts.
Use only the Compac supplied 4 bolt mounting plate to secure the
DCA to the post.
Feed the wiring into the DCA cabinet using appropriate glands and plug any unused
holes in the cabinet.
Mount the cover plate onto the post using the supplied button head cap screws. The
cutout goes to the bottom of the post.
No open holes in the base of the DCA cabinet are permitted. Any
unused holes in the bottom of the DCA cabinet must be blanked.
Guidelines for Mounting the
DCA on a Wall
If the DCA is to be mounted on a wall, it needs to be attached to a bracket that bolts
to and supports the unit from underneath. No holes are to be made in the back of
the cabinet unless specifically approved by Compac. All wires into the cabinet must
be glanded and all unused holes in the base must be blanked.
Security Guidelines
To help prevent the possibility of unauthorised tampering, it is recommended that
tamper resistant fasteners be used and that all wiring outside the cabinet be
enclosed.

Precautions when 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:
Install 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.
Start up
1. Before starting a generator, make sure the power to the unit is turned off.
2. Start the generator, let the generator reach stable operating speed and wait
30 seconds before reconnecting the power to the unit.
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.
Shut down
Isolate the unit before shutting down the generator.
