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

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 Console,
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 following 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.

reinforced
corrugated box and obtain
suitable packing material such
“Pakon”
as
polyurathene foam
polystyrene foam chips. Fill
the bottom of the box with at
least two inches of packing
polethefoam chips,
chips, or
material. Make certain the
component is firmly packed.
Remember to include a note
describing
malfunction along
the particular
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.

BOARD BY BOARD ANALYSIS
The TRANSAC 12A consists of
seven
of these components has a
major components.
Each
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
17
current source of approximately
+40VDC at 40MA which are not
critical.
Each operating
voltage is fused to protect the
supply against damage.
An AC
input fuse is provided for
console protection.
The
TRANSAC 12A power supply is
also equipped with a thermal
(heat sensitive)
protection
device
which will remove AC
power from the power supply in
the event the console interior
temperature
exceeds
+235
degrees F.
This condition will automatically
correct itself when
the
cause for the overheating is
eliminated.
The Power Supply also generates
a power Fail signal.
This
signal is used to notify the
console processor
board when
AC power is removed.
The
Processor Board will then store
all the console totals memory.
If the power fail timing or
voltage levels are incorrect,
the console could lose memory.
Thus,
the power supply could be
responsible
for console memory
loss.
The Processor Board in the
TRANSAC 12A console is respon-
sible for
all communication
between the console and the
dispensing units (e.g., genera-
ting PUMP SELECT codes, sending
AUTHORIZE, preset, etc.)
The
Processor Board also accepts
all keyboard inputs,
mode
switch and keyswitch inputs.
The Processor Board sends codes
to the display board for use in
generating readouts and status
indications.
The audible
signals from the console are
also generated on the Processor
Board.
The Processor Board is
also responsible for all totals
and Inventory functions (Except
the individual PUMP TOTALS)
Most
totals or
inventory
problems
will be traced to
operator
error or
programming
error,
however if no valid
programming error is detected
the Processor Board is to
blame.
Memory
retention is
also done by
the console
Processor Board and this board
should be replaced first in the
event
of memory loss.
The
Keyboard selects the functions
of the TRANSAC 12A console.
Each key is a separate reed
switch used to make a connec-
tion into the Processor Board
when depressed.
The KEYSWITCH selects different
modes
of operation
of the
console.
Each key position
makes a
connection
into the
KEYBOARD and from there into
the Processor Board.
The Display Board contains all
circuitry
necessary to drive
the Seven Segment LED displays
and the indicator LED’s both on
the Display Board and also on
the LED board.
The Display
Board receives coded informa-
tion from the Processor Board
and drives the display and LEDs
accordingly.
TROUBLESHOOTING GUIDE
General Information
Any difficulty encountered with
the T-12A HI11 system will be
in
one of three areas:
The
console,
the field wiring, or
the Highline dispenser(s).
The
first step
in troubleshooting
the system
is to localize the
problem to one of these three
areas.
It is possible to
localize a problem using the
diagnostic
checks built into
the TRANSAC 12A console.
This
process is explained in the
diagnostic section of the
TROUBLESHOOTING GUIDE.
As a

DATA LOOP CHECKOUT
The following tests are used to
verify the field wiring and
also to verify correct opera-
tion of the data loop.
First,
the serviceman should look into
the distribution box and verify
that the Data Loop continuity
indicator is lighted. As
explained earlier
in this
manual,
the data loop must be
complete (have continuity) in
order for any dispensing unit
to respond
to the console.
If the Continuity Indicator is
not lighted,
the first step is
to determine if the problem is
in
a dispenser or in the
console distribution box.
1.
Turn all Normal/Isolate
switches to ISOLATE.
If the
Continuity
Indicator now comes
on 9
skip to Step 4.
If the
Continuity
Indicator does not
come on,
continue.
2.
Unplug the two data wires
(one black and one red) coming
from the console and short the
two wire ends together.
Enter
Test mode,
then press keyboard
5 and AUTHORIZE.
The console
display should ready 00.
(This
indicates the console data loop
power supply and the data cable
to the distribution box are
okay.
If the display reads 00,
the distribution box P.W.B.
T12679-G1 must be replaced. If
the console displays read 01 or
02, continue.
3.
Unplug the end of the data
cable in
the Transac 12A
console.
(Red and Black wire
which plug
into the piggyback
board on the power supply)
Tie
the two pins coming up from the
board together with a piece of
wire.
Now press keyboard 5 and
then AUTHORIZE.
The console
display should read 00.
(This
tests the data loop current
source)
If the console display
does read 00,
replace the data
cable (N20953-Gl)
If the
console display reads 01 or 02,
replace the current source
RI 5257-Gl.
4.
Turn the NORMAL/ISOLATE
switches being
used to NORMAL
one at a time (in pairs if the
field wiring bridges two switch
positions)
and observe the
Continuity Indicator.
Any
dispensing unit whose wiring is
broken or which has a two-wire
defect will prevent the Conti-
24
nuity Indicator from lighting
when these NORMAL/ISOLATE
switch(s) are switches to
NORMAL.
When you have deter-
mined
which
dispenser or
dispensers
are keeping the
Continuity
Indicator off,
continue to the next step.
5. Open the AC Junction Box of
the suspect dispensing unit.
Disconnect the two data wires
(A9 and A19) from the field
wires.
Connect the two field
wires
together.
Put the
NORMAL/ISOLATE switches
for
this position on NORMAL.
The
Continuity
Indicator
should
light.
(This
verifies the
field wiring
for this posi-
tion)
If the Continuity
Indicator does not light, the
field wiring is defective and
must be replaced.
If the
Continuity
Indicator does
light, this verifies that the
problem is in the dispenser.
6.
Put the NORMAL/ISOLATE
switch in the ISOLATE position
to complete the loop for the
other hoses and refer to the
H-III service manual to trou-
bleshoot the dispenser.
Once the data loop is complete
through each dispenser as
indicated by
the Continuity
Indicator
being
lighted,
proceed
with the following
steps to verify the loop and to
verify that each dispenser is
responding
to the console.
1. Enter the test mode.
Press
keyboard 5 and then AUTHORIZE.
The console display should read
00 indicating the two wire
system is okay.
The pump number of each dis-
pensing unit
which is respond-
ing to the console will appear
on the console beginning with
the highest dispenser and
counting down to the lowest
dispenser number.
Any dis-
penser whose number does not
appear is not responding and
should be verified as to the
correct Pump
Selector Switch
setting and two wire switch
positioning.
To leave the Diagnostic mode of
operation, it is necessary only
to turn the keyswitch to
OPER.
2. Press keyboard 6 and then
AUTHORIZE.
