This service manual will help you prepare your WI-150 indicator for use.
This manual covers the following:
• Introduction
• Operational Modes
• Sealing the Indicator
• Keyboard
• Configuration Mode
• Adjusting Dead Load
• Calibration Procedures
• Reset Menu and Master Clear
• Board Schematics and Parts Lists
The WI-150 operates in three modes:
• operations mode
• test mode
• configuration mode
Operations mode contains all normal weighing operations. In this mode you
can view or set any of the following parameters if the unit is so configured:
• cutoff control
• pushbutton tare
• one to ten keyboard tare registers
• one to eight cutoff values
• identification number
• time
• date
Any combination of these items can be secured behind a security code. Any
items secured by the code number can be viewed but not changed. Opera-
tions mode is fully explained in the User's Manual .
Use this mode to perform tests on the WI-150. The test mode is covered in
the User's Manual .
Use this mode to set up options and program the operation of the scale and
indicator. Configuration is explained fully in the Configuration Mode section
of this manual.

Sealing the Indicator
The WI-150 can be sealed. If sealed, no configuration items can be changed
in the configuration menu. Seal the unit by placing switch S1-1 in the OFF
position. Unseal the unit by placing S1-1 in the
ON position. Remove the front panel of the
indicator to gain access to switch S1-1. The
switch is located near the center of the PC
board behind the display and looks like the
diagram at right. S1-3 and S1-4, which connect
the
WI-150's ON/OFF keys to the appropriate
circuitry, should always be in the ON position to
allow optimal functioning of the indicator. S1-2

Configuration Mode
This section of the manual explains how to set up and view parameters in the configuration mode for software
revisions 45790-0025J (battery pack) and 45790-0017L (AC-powered). Note that earlier software may not have all of
these programming selections. Follow the configuration menu and instructions in Figure 2 to set up the WI-150
indicator to suit your specific needs. Below are explanations for each section of the menu. The non-bold heading for
each section is the pathway you follow on the configuration menu to get to the parameter or parameter options
shown in bold text. The menu reflects a WI-150 model with time and date and other options installed and enabled.
Your system may differ.
Sidestepping Security Code Entry to Configuration
In case you forget the security code or the security code is altered without your knowledge, access
the configuration menu as follows: First, flip switch S1-1 to the OFF position (sealed). Next, enter
the default code number, 150. Get into the configuration menu as instructed in the key to Figure 2.
When
CODE NO. is displayed in the menu, flip switch S1-1 from OFF to the ON position. Under-
stand that opening the indicator to access the switch effectively unseals the indicator! Then enter a
new code number—twice, as the display prompts. Now you have complete access to the configura-
tion menu.
SC-150 This parameter allows you enable or disable the SC-150. The default setting is “no.”
Setup ↓Scale ↓Units ↓

Under each unit of measure you have the option of selecting ON or OFF. Choosing the OFF option under a
unit of measure disables that unit of measure. If a unit is disabled, it will not appear in the configuration menu
under CAPACITY or DIVISION nor will you be able to choose it during weighing procedures. Also, if gallons
is disabled, DENSITY will not appear in the configuration menu.
Setup ↓Scale ↓Units →Capacity ↓
Pounds →→
→→
→1000g →→
→→
→Gallons
This menu section lets you set the scale capacity for those units of measure enabled under UNITS . Capacity
is automatically converted--entering the capacity for either lbs or kgs automatically sets the capacity of the
other unit.
Capacity for gallons is determined according to density and cannot be entered since it is a function of weight,
not volume. Density is the weight of your material calculated in grams per cubic centimeter. Consult an
Engineering Handbook for the density of your material. If a liquid you are weighing has a specific gravity of
1.5, for example, you take 1.5 times 8.336 to find out how much each gallon of your liquid weighs.
Setup ↓Scale ↓Units →Capacity →Division ↓
Pounds →→
→→
→1000g →→
→→
→Gallons
This option lets you set the division size for the units of measure enabled under UNITS . Division size is
automatically converted--entering division size for either lbs or kgs automatically sets the division size for the
other. Division size for gallons is independent.
One feature not readily apparent is that the number of displayed leading zeros can be specified. For example:
for 10 pound divisions, if you want 5 zeros displayed when no weight is on the scale, key in 00010 for a
division size. The display will read 00000 when the scale is empty. If you want two zeros displayed when the
scale is empty, key in a division size of 10.

Setup ↓Scale ↓Units →Capacity →Division →
DensityThis option lets you set the density of the liquid you are weighing in grams per cubic centimeter. Your scale
will then convert the weight of the liquid into gallons. (Specific gravity is identical to density as expressed in
grams per cubic centimeter.)
Setup ↓Scale ↓Units →Capacity →Division →Density →Zero ↓
-Percent,Percent
With this option you can set the plus and minus percent of capacity the indicator can zero. For example, if the
capacity of the scale is 10000 lb and the zero range is ±2%, key in 2 for both the positive and negative
ranges. You may key in decimal values.
Setup ↓Scale ↓Units →Capacity →Division →Density →Zero →
Stability
This option lets you set the size of the motion detection window in divisions. You may enter decimal values
less than one or up to 999999 which turns off the motion detection.
Setup ↓Scale ↓Units →Capacity →Division →Density →Zero →Stability →A.Z.T. ↓
Range,Net
Range - With this option you can set the ±automatic zero tracking window in scale divisions. To turn off AZT,
enter a range of 0.
Net - If an AZT range is set, NET will appear in the menu. This option lets you choose to enable AZT during
net weighing operations ( ON ) or disable it ( OFF ). The gross weight must be zero for AZT to work in net
mode.
Setup ↓Scale ↓Units →Capacity →Division →Density →Zero →Stability →A.Z.T. →
Update This option sets the display update rate. You may choose from among 1, 2 or 5 times per second.
Setup ↓Scale ↓Units →Capacity →Division →Density →Zero →Stability →A.Z.T. →Update →
Average
This option allows you to choose the number of display period(s) over which the data are internally averaged
prior to being displayed. Any number between 1 and 10 may be entered.
Setup ↓Scale →Options ↓
ControlChoosing
ON enables the cutoff control function. OFF disables this function. If cutoff control is disabled,
CONTROL will not appear in the SECURITY section of this menu or in the Operations Menu. Note, however,
that for CONTROL to appear in the Operations Menu, the number of outputs selected under CUTOFFS in the
OPTIONS section of this menu must be a non-zero value.
Setup ↓Scale →Options ↓Control →Tare ↓
Button,Digital
Button -Choosing ON enables the pushbutton tare. Choosing OFF disables the pushbutton tare.
Digital - Select the number of tare registers you want by keying in a number. You can choose 0 through 10

Total—This option lets you choose the number of cutoffs you want by keying in a number. If you choose 0
(zero) cutoffs, CUTOFFS will not appear in the SECURITY section of this menu or in the Opera-
tions Menu. Also, in order for CONTROL to appear in the Operations Menu, a non-zero number
must be entered.
Ingred.—This option lets you choose the number of cutoffs you wish to be “ingredient cutoffs”by keying in a
number. If you pick 0,
INGRED. will not appear in the menu and the cutoffs you have will be
“setpoint cutoffs.”Cutoffs occur according to weight. The lightest cutoffs occur first, followed by
the heavier ones. See Viewing and Setting Cutoffs in the User's Manual .
Latched—Selecting "yes" means that once a cutoff output is turned off, it is to stay off until control is halted
and then started again. Further, once all cutoffs are off, the control is automatically halted. Select-
ing "no" disables this behavior. LATCHED is offered only if CONTROL is enabled under OPTIONS
and the total number of cutoffs is not zero. Default = yes.
Setup ↓Scale →Options ↓Control →Tare →ID →Cutoffs →
Hour With this option you can choose to have the clock disabled (
OFF ) or the mode of clock you want. You can
choose the 12 hour clock display or the 24 hour clock display. If the clock is disabled, HOUR will not appear
in the S ECURITY section of this menu and DAY will not appear in the OPTION S or SECURITY section of this
menu.
Setup ↓Scale →Options ↓Control →Tare →ID →Cutoffs →Hour →
Day This option lets you choose to disable the calendar (
OFF ) or choose the mode of calendar display you want.
You can choose to display the days (dd), months (mm), and year (yy) as mm dd yy, or dd mm yy, or yy
mm dd. If DAY is disabled, DAY will not appear in the SECURITY section of this menu.

EnquireThis option is not seen on the battery-powered version of the WI-150. On the AC//DC powered version this
sub-menu allows you to choose a printer or other device which will send an enquire code to the indicator.
You may select the ASCII code number you wish to act as the enquire code number. ASCII decimal 005 is
the default value. If a device sends the enquire character to the indicator, the indicator will transmit weight
data. If a computer sends the enquire character, the Button, Auto and Broad. selections are overridden and
will not function.
Under the Enquire, Device option, if "Printer" is selected, the display will freeze while printing, and if printing
is timed-out, a recovery menu is presented. If "Other" is selected, data are transmitted without affecting the
front panel operation.
Setup ↓Scale →Options →Security →Serial A/B ↓Print ↓Button →Enquire →
Auto With auto print enabled, the indicator automatically transmits data when the scale weight stabilizes at greater
than 1% of capacity. To print again, scale weight must fall below 1% of capacity and stabilize above 1% of
capacity again. OFF disables the auto print feature. ON enables the auto print.
Setup ↓Scale →Options →Security →Serial A/B ↓Print ↓Button →Enquire →Auto →
Broad. Broad. stands for broadcast. If you enable (
ON ) broadcast, the weight data to be transmitted are updated at
the display rate. Choosing OFF disables the broadcast. If broadcast is enabled, the Button, Enquire, and
Auto selections are overridden and will not function.

Layout
Use this print-layout option to customize the physical arrangement of your printed information. The next
several pages deal with the layout of your printed output. The rest of the documentation on configuration
follows this layout section.
You may print eight items:
•Time •Date
•ID number •Gross weight
•Net weight •Tare weight
•Displayedweight •Custom wording you choose
There are eight print commands you use to print these eight items. They are:
Print Command Item Print Command Item
HOUR Time NET Net weight
DAY Date TARE Tare weight
ID ID number DISPLAY Displayedweight
GROSS Gross weight ASCII Custom wording (ASCII string)
Figure 3 shows a sample of the default printout generated when you press the PRINT key on a new indicator
and the layout menu in Figure 4 shows the default order of print commands. Notice that the time, date, and
ID-number items do appear in Figure 3. The print commands for time, date, and ID-number are present in the
default print-layout menu, and these items are enabled under OPTIONS in the configuration.

11
The default layout menu can be changed to suit your needs. Any of the eight
print commands can be deleted or rearranged to accomplish this
customization. Figure 4 shows the default layout menu.
As in the other WI-150 menus, the SELECT key opens up the next level of
the menu. There is one more level of information under the print commands
in the layout menu. This information may be one of two types:
•an ASCII string or
•a layout submenu.
ASCII strings are stored under the ASCII print commands, such as Nos. 1,
3, 5, 7, etc. (see Figure 5). An ASCII string is a sequence of ASCII code
numbers. Each code number is preceded on the indicator display by a
sequence number. See Figure 5. You view these sequence numbers and
ASCII code numbers by repeatedly pressing MENU. These ASCII strings
contain the codes for your custom wording.
Figure 5 shows the default ASCII string under the 1 ASCII print command.
Table 1 shows the relationship between this sequence of codes and the
output of the printer. You can change the ASCII string or delete it entirely to
suit your needs. To delete an ASCII print command from the layout menu
you first need to delete the entire ASCII string which is stored in that ASCII
print command.
Find complete instructions for these procedures in the section Examples
and Step by Step Instructions .
In Figure 5, the MENU key advances you through the ASCII control-charac-
ter displays. The SELECT key returns you to the 1 ASCII display.

ASCII Strings
ASCII is an acronym for
American Standard Code for
Information Interchange. ASCII
codes are just numbers a
computer can translate into
letters, numbers and instruc-
tions. See Table 2.
Remember, press SELECT to move up or down a level in the menu structure, and press MENU to

Example A: If you want to change the second print command in Figure 4
from 2 HOUR to 2 TARE, with 2 HOUR displayed, press SELECT. Now
scroll to the TARE print command in the submenu and press SELECT to
select it. The print command 2 HOUR is now changed to 2 TARE.
Example B: If you want to delete the second print command (2 HOUR) in
Figure 4: with 2 HOUR displayed, scroll to DELETE in the submenu under 2
HOUR and press SELECT. This deletes the 2 HOUR print command from
the layout and 3 ASCII becomes 2 ASCII, 4 becomes 3, etc .
Below is a list of procedures to customize your layout. The steps for each
procedure are explained below the list. Use the appropriate procedure or
procedures to customize the layout to your liking. These step by step
instructions relate to the layout shown in Figure 5.
•Deleting one ASCII code from an ASCII string
•Deleting all the ASCII codes in an ASCII string
•Deleting an ASCII print command after the ASCII codes are deleted
•Deleting a non-ASCII print command from the layout menu
•Inserting a print command in the layout menu
•Adding ASCII codes to an ASCII string
For example, to delete the hyphen in
WEIGH-TRONIX you need to delete
the ASCII control code for the
hyphen. In Table 1 you can see that
this is #45. In Figure 5, the 9th ASCII
control code is code #45.
With 9 45 displayed, press CLEAR,
then press +/-. . . CLEAR deletes the value, and +/-
deletes that step in the string. When
you deleted #9, #10 becomes #9,
etc.
For example, to delete the entire line
of text at the top of the printout
shown in Figure 4 you need to delete
all the ASCII control codes under the
1 ASCII display shown in Figure 5.
With the first ASCII control code of
the string displayed (1 31) , press
CLEAR, then press +/-. Repeat this
two-step process until END is
displayed. When END is displayed
press SELECT . . . 1 ASCII is displayed. All the control
characters under it are now gone.
Examples and Step by
Step Instructions
Deleting one ASCII code
from an ASCII string
Deleting all the ASCII codes
in an ASCII string

14
To repeat any ASCII code,
instead of entering it multiple
times, enter the code number,
then a decimal, then the
number of times you want that
code repeated. For example:
To enter seven carriage
returns, enter 13.7. To enter
two capital letter Os in a row,
enter 79.2.
You may insert new codes in
an existing ASCII string.
Display the code you want the
new code to precede and press
±. A cursor appears and you
may enter the new code
number. All the following code
numbers move down one
position in the sequence.
With 1 ASCII displayed, press
CLEAR . . . The item is removed from the menu
and all the following items move up
one number value on the menu.
What was item 2 becomes item 1,
etc.
For example, to delete 2 HOUR
from the menu, display 2 HOUR ,
then press CLEAR . . . The item is removed from the menu
and all the following items move up
one number value on the menu.
What was item 2 becomes item 1,
etc.
For example, let's reinsert HOUR in
the #2 position. Display 2 ASCII, the
menu item currently in the #2 position.
Press +/-. . . The layout submenu shown in
Figure 7 appears. Scroll through the
menu by pressing MENU. When
HOUR is displayed press SELECT.
2 HOUR is displayed showing that it
has been inserted in the second
position. 2 ASCII becomes 3 ASCII,
etc.
For example, let's say you've just
created a new ASCII print command
in the #1 position in the menu
(1 ASCII). To insert new codes,
display 1 ASCII , then press
SELECT. . . 1 _ is displayed.
Key in the control code you want and
press MENU. . . 2 _ is displayed prompting you for
the 2nd control code in the ASCII
string.
Repeat this step until you have
entered all the ASCII control codes
you want or the indicator tells you the
memory is full, then press
SELECT. . . 1 ASCII is displayed in this ex-
ample.

Full When selected, the indicator will display the last value used or the default value. You enter the full capacity of
the analog output which may be less than or greater than the capacity of the scale. For example, the capacity
of the indicator may be 5000 lb, but it may be desirable to have 3000 lb as the full capacity of the analog
output. In any case, the analog output has nominal under range and over range limits of 20%.
Setup ↓Scale →Options →Security →Serial A →Serial B →BCD →Analog ↓Output →Units →Full →Adjust ↓
Zero →Full →End
The choices present under ADJUST allow the zero and the span of the analog outputs to be adjusted without
actually putting weights on and off the scale.
Selecting ZERO lets you adjust the zero of the analog output for a zero weight reading. This is done by
pressing the 0, 1, 2, 3, or 4 key to increase the output and by pressing the 5, 6, 7, 8, or 9 key to decrease the
output. The number on the display gives a visual representation of the zero setting, with 00.000 being the
nominal value. The zero adjustment has a ±10% range, -10.000 to +10.000 on the display.
Selecting FULL lets the operator adjust the span of the analog output for the full capacity weight reading. The
keys and the number on the display function like the zero adjustment above, with 100.000 as the nominal full
capacity value. The span has a +/- 10% range, 90.000 to 110.00 on the display. Weight does not have to be
on the scale to perform this task.
When ZERO , FULL , or END are displayed, the analog output follows the value selected under OUTPUT and
UNITS . The only time the value is not output is while actually adjusting zero or full.

The dead load offset adjustment provides compensations to cancel out the
weight of the scale platform and any permanently fixed weight supporting
structures on the platform. Adjusting the dead load should be completed
before calibration of the Indicator.
To adjust the dead load:
1. Enter the test menu by pressing and holding the MENU key until TEST
is displayed. Then proceed to the A to D display by following the
directions in the box below:
2. While A to D is displayed, press PRINT/SELECT.
3. Access the junction box on your scale and adjust the zero balance
potentiometer until the indicator displays a zero weight or an amount
very close to it.
The dead load offset is adjusted and your indicator may now be calibrated.
