GENERAL DESCRIPTION
BASIC FEATURES OF THE TRANSAC
12A SYSTEM
* Each consol? has a maximum
capability of controlling
twelve hoses (H-IIIB pumps
or dispensers in any combi-
nation of singles and
duals). The console can
also operate up to 6 MPD
units.
* Each console will monitor
the product inventory for
four grades.
* A low level inventory warn-
ing can be programmed into
the console to alert the
console operator if product
inventory gets too low.
t The console will handle pre-
pay sales (The customer pays
for a specific amount of
product before the deli-
very). A Prepaid sale is
indicated on console display
* The console will handle
Postpay sales (The customer
pays the cashier after the
delivery).
* The console will also handle
Preset-Postpay sales (The
customer desires a specific
amount of product but pays
after the delivery).
* The console can be program-
med to Preset based on
volume or money amounts.
* The console has Status Indi-
cators for each pump to
inform the operator of the
status of each pump (Call,
AUTHORIZED, Delivery in
progress, Payment Due).
The console will read the
dollar and volume amount of
each purchase.
The console will set and
read the prices for all
pumps (Central Price Set-
ting). Two level pricing
for each grade can also be
selected.
The console has buffer
memory capabilities (This
allows back-to-back sales on
the same hose with the
console retaining the sale
amounts of each sale).
The console has an EMERGENCY
STOP button allowing the
operator to stop all deli-
veries and a PUMP STOP
button allowing the operator
to stop individual pumps.
The console has the capa-
bility for automatic de-
authorization of a pump if
the pump is not used within
a programmed time period.
The console provides SHIFT
and STATION TOTALS by grade
as well as various cash
totals as explained later in
this manual.
The console is equipped with
a battery backup system to
retain all totals and
inventory information for a
minimum of 72 hours if the
AC power is interrupted.
The console can be used to
put any or all pumps in a
MANUAL or Full Service mode
while still retaining full
totals and inventory data.

DISPENSING UNITS
The dispensing units which
complete the Transac 12A system
are Highline 111 electronic
dispensing units. The H-111
may be either self-contained or
remote dispensers in either
single or dual configuration.
Installation instructions are
shipped with each dispensing
unit which contains foundation
layouts and general information
import ant to installing the
dispensing unit with the
Transac IZA.
When the Transac 12A is to be
utilized with a dual H-111,
care must be taken to set the
dispensing unit on the island
facing in the correct direc-
tion. The numbering sequence
of the dispensing units must be
determined before the dispens-
ing units are bolted to the
foundation. H-111 duals must
be placed on the island so the
A side of the dispenser corres-
ponds to the lower hose posi-
tion number of the Transac 12A
console. The A side of a dual
H-I’ll is the left side of the
dispenser as seen facing the AC
junction box. To relate an
H-111 hose to the desired
button position (hose number)

On the Logic Board you
will see a rotary switch.
Turn the rotary switch to
establish the console
button number that will
control the hose on the
left side.
In the case of a dual dis-
pensing unit, the hose on
the right side will automa-
tically be controlled by
the next higher button
number (hose number) on the
Transac 12A.
In the event the dispens-
ing unit is placed on the
island incorrectly, Kit
K89752 will allow PUMP
NUMBERS to be selected
individually for each hose
of the H-IIIB dispensing
unit. This kit is not
necessary if Logic Board
WO1520 is installed.
For assigning each H-IllB
to a particular grade on
the TRANSAC TWELVE A
console, refer to the
following three pages.
,
CAUTION: All switches MUST
be set correctly
prior to applying
power to the H-IIIB
dispensing unit.
NOTE: The MPD cannot be
assigned to Grade 4
on the T-l2A console.

Logic Board WO1520 for the H-111B has been modified to incorporate
jumpers in all locations where switches were used in the past. The
following information is provided to assist the serviceman in proper
setup of the WO1520 Logic Board for any particular application. It
is suggested that the serviceman retain all jumpers removed for
later use. These jumpers are located,where the switches on page 6
are shown.
NOTE: A jumper in place is “IN” and a jumper removed is “OUT”.
Jumper group JPC is used to determine the grade assignments for the
A and B side of the unit. Jumpers JPC 4, JPC 5, and JPC 6 determine

INSTALLATION INFORMATION
SITE CRITERIA
Few restrictions are imposed
upon the installation site for
the Transac System, since this
system was intended for varied
service station layouts and
dispensing requirements.
Mostly, the Transac System will
be installed in a new service
station constructed especially
to accommodate it, but the
system may also be installed at
sites that are renovated to
accept it. Following are the
criteria that should be met for
any type of installation
site:
1. Installation shall be in
accordance with the Na-
t ional Electrical Code
N.F.P.A. 70 and the flam-
mable and combustible
liquids code N.F.P.A.
30.
2. An enclosed weather pro-
tected structure must be
located on the site for
housing the Control Con-
sole, Distribution Box and
wire troughs. The ambient
temperature within the
structure for system
operation should not exceed
130 degrees F. This
maximum room ambient is
allowable if the units are
allowed free circulation
of air and will be reduced
if this is restricted by
close enclosure in wooden
cabinetry, etc.
3. The Control Console should
be located such that the
operator has an unob-
structed view of all hose
outlets.
4. Since the standard length
of cable from the control
console of the Distribution
Box is 10 feet, planning
should include locating
these units within this
distance limitation.
5. Foundation layouts, which
are included with the
dispensing unit shipped to
the site, are to be used in
construction planning.
PREPARATION REQUIREMENTS
Prior to actual installation
of the Transac System, an
inspection of the delivered
equipment should be made to
insure that the necessary
installation materials are on
hand and that the site meets
with the installation require-
ments. Once the preparation
details as given in the fol-
lowing paragraphs are satis-
fied, installation of the
system can be undertaken in
accordance with the instruction
in this section.
UNPACKING EQUIPMENT
When the equipment arrives at
the installation site, each
unit should be inspected for
possible shipping damage. If
damage is evident, it should
be reported directly to the
carrier. Shipping damage is
not covered by the warranty
agreement. After inspection,
place equipment back in the
shipping cartons to prevent
exposure to dust or dirt and
store indoors until ready for
installation.

RETURN OF COMPONENTS CONDUIT REQUIREMENTS
Components returned to Gilbarco
under warranty or for repairs
are subject to severe shipping
damage if not packaged pro-
perly. Return in original
shipping cartons if possible.
Use a durable reinforced
corrugated box and obtain
suitable packing material such
as “Pakon” polethefoam chips,
polyurathene foam chips, or
polystyrene foam chips. Fill
the bottom of the box with at
least two inches of packing
material. Make certain the
component is firmly packed.
Remember to include a note
describing the particular
malfunction along with return
shipping information. It is
also recommended that the
package be fully insured.
All returned items must be
accompanied by an RGA form.
WARNING: If the component
arrives at Gilbarco in a
damaged condition and it is
ascertained that the damage was
a direct result of inadequate
or improper packing, such
damage will not be covered
under the original factory
warranty and the customer will
be held responsible for the
cost of repair necessary to
correct said damage.
MATERIALS REQUIRED
Data wire field terminations
are done in the Distribution
Box on terminal blocks; TB-1,
TB-2, TB-3, by stripping each
wire l/4 inch and crimping on
STA-KON terminals. A re-com-
mended type is Thomas and Betts
part number RB1113. Care
should be taken to crimp the
STA-KON on correctly.
One 3/4” conduit is required
for each dispensing unit -
single or dual - RC dispenser
or self contained pump.
A wire trough in the area of
the Distribution Box for
termination of the conduits
from the dispensing units and
routing of wiring will be
necessary for making the
necessary submerged turbine
pump control wire connections
for RC dispensers.
INSTALLATION INSTRUCTIONS
These procedures are to be
followed to insure proper
installation of the Transac
System with regard to meeting
the requirements of the Nation-
al and Local electrical codes,
economy of costs, and correct
operation of the system.
Careful, step by step planning
of the installation can prevent
errors which are both costly
and time consuming to correct.
1. All conduits and wiring
must be installed to meet
the requirements of Nation-
al and Local ‘electrica.
regulations and codes.
2. Running two larger conduits
to two contractor-installed
junction boxes and then
running smaller conduits
between these junction
boxes and the dispensing
units is permissable.
However, past experience
has proven this method to
be more expensive and more
susceptible to wiring er-
rors than running separate
conduits to each dispensing
unit.
9

3.
4.
.
5.
6.
7.
The threaded connections
on all conduits must be
drawn up tight.
When pulling wires through
conduit, avoid damage to
the wire insulation.
When making wire connec-
tions, use of U/L listed
wire connectors which
provide a secure connection
is recommended. Pay par-
ticularly close attention
to multi-wire connections.
Foundation layouts will be
found with the dispensing
units shipped to the site.
DO NOT APPLY AC POWER TO
THE INSTALLED SYSTEM
WITHOUT FIRST PERFORMING
THE INITIAL CHECK OUT
PROCEDURES GIVEN IN THIS
SECTION.
8 . . Cabling and wiring connec-
tions for installing the
Transac System are shown
on the last pages of this
book. To find the appro-
priate installation draw-
ing, look in the title box
and select the title that
describes the particular
type of installation. It
may be necessary to refer
to more than one drawing to
cover all portions of the
installation. This instal-
lation drawing is to be
used as a guide only, since
every installation is a
special situation which
cannot possibly be covered
here in exact detail.
9. If an intercom system is
to be installed, separate
conduit and 3 wire shielded
cable are to be run between
the attendant’s office and
island speakers. The
island speaker must be
installed a minimum of four
feet above the island and
18 inches from any dispens-
ing unit in accordance with
National and Local electri-
cal codes.
INITIAL CHECK OUT
After the Transac system is
installed, the wiring and
system components are to be
verified for correct operation
by the procedure given in the
subsequent paragraphs.
TESTING EQUIPMENT REQUIRED

slowly. Press PUMP SELECT
#I then CASH to clear this
payment due signal.
6. Verify the Console readout-
Money and Volume. Record
this amount under Transac-
tion #I for pump #I on
Chart W2. Verify that the
Grade Light for this pump
grade is blinking. (Low
Inventory Warning Level)
If not, recheck programming
according to MDE-1578.
7. Preset pump #I for a $.50
delivery.
8. Raise the Operating handle
on #I and allow the pump to
deliver product until IT
STOPS ITSELF. (Within $.76
of $.50)
9. Lower the pump Operating
handle (OFF).
10. Clear the console payment
due signal.
11. Record the amount Preset
and the amount. delivered
under Transaction #2 for
pump #I.
12. Repeat steps 7-10 THREE
more times recording the
amount Preset and the
amount delivered each time.
(Make sure to allow the
pump to STOP ITSELF each
time) NOfE: If by Trans-
action #5 the H-IIIB will
not Preset accurately,
refer to MDE-1495, H-111B
Installation and Service
Manual.
13. Add the amounts delivered
in the five transactions
for each hose and record
the total on Chart #2. The
ENDING PUMP TOTALS must
equal the BEGINNING PUMP
TOTALS plus the total of
transactions l-5. If not,
refer to MDE-1495, H-IIIB
Installation and Service
Instructions.
14. Record all console SHIFT,
STATION, and INVENTORY
totals on Chart #I. (Under
ENDING TOTALS) Add the
delivery volume totals from
step 13 for all pumps
assigned to Grade 1. This
volume amount must equal
the volume amount for Grade
1 on Line 7 of Chart 1.
The Grade 2 volume totals
must equal the Grade 2 line
7 amount. The Grade 3
volume totals must equal
the Grade 3 line 7 amount.
The Grade 4 volume totals
must equal the Grade 4,
line 7 amount. If any of
these totals do not agree,
check the Grade Selector
switches on all the pump
Logic Boards. Also verify
that all Grade 4 hoses were
programmed correctly
according to Page 4.
15. The money amount of all
transactions on Chart 82
added together must equal
the total money figure on
line 7 of Chart #I. If
not, recheck console
programming and refer to
the Troubleshooting section
of this manual.
16. Line #9 of Chart 1 must
be within one unit of Line
#8 . This indicates that
console inventory accumu-
lation is accurate.
17. Verify at this time that
the dispensing unit
mechanical volume totals
have increased the same
amount as the dispensing
unit electronic volume
totals. This insures the
dispensing unit is deli-
vering accurately.

SERVICE INFORMATION
FUNCTIONAL DESCRIPTION
The Transac 12A Highline 111
system is a solid state self
service system utilizing the
latest in microprocessor
technology. The console and
dispensing units are electri-
cally connected in a series
loop as shown in the figure
below:
Any break or discontinuity in
the series loop would result in
complete loss of console
control. To prevent this from
occurring each dispensing unit
has two wire brought into a
distribution box where by using
switches any dispensing units
can be isolated from the loop
and restore loop continuity to
allow console control of the
remaining dispensing u.nits.
In the 12A, H-111 system the
console is in communication
with the dispensing units and
gets transaction data from each
unit in the loop. Each dis-
pensing unit has an address
code determined by the Pump
Number Selector Switch as shown
in the Installation Instruc-
tions. The console sends out
a different code for each PUMP
SELECT button that is depres-
sed. This code is sent to all
the dispensing units in the
loop. Only the unit with the
correct address code will
respond to the console. From
this it is easy to see that any
dispensing unit may be assigned
to any PUMP SELECT button by
the PUMP NUMBER SELECTOR switch
and not by its physical loca-
tion or the wiring position in
the distribution box. For any
fill-up or preset transaction
the console sends the informa-
tion (price level, preset
amount (if any) and authoriza-
tion) through the data loop and
the assigned dispensing unit
will receive and act on this
information. In the Transac
12A system, price setting is
done on a grade basis. The
Grade Select switches for each
H-IIIB dispensing unit deter- ’
mine the grade for that unit
and therefore the price it will
accept from the console. Only
Grade 4 requires programming of
Grade Assignment from the con-
sole. All totals information
except the individual PUMP
TOTALS are retained in the
console memory and may be
cleared or reset. Pricing
information is sent by the
console but is retained by the
individual dispensing unit.
In the event any problem is
encountered with Shift, Sta-
tion, or Inventory totals
accumulation, verify console
programming.
BOARD BY BOARD ANALYSIS
The TRANSAC 12A consists of
seven major components. Each
of these components has a
separate function, but all must
be functioning together cor-
rectly to allow the TRANSAC 12A
to control the H-III dispensers.
The POWER SUPPLY MODULE derives
the low level DC voltages
required by the console and the
data loop from 110 VAC. The
operating voltages of the
TRANSAC 12A are +SVDC, -5VDC,
+12VDC, +BVDC and a constant
