WI-125 SST Indicator Service Manual
This service manual will help you prepare your WI-125SST indicator for use.
This manual covers the following:
• Introduction
• Operational Modes
• Sealing the Indicator
• Keyboard
• Configuration Mode
The WI-125SST 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 the following parameters if the unit is so configured:
• pushbutton tare
• quick keypad tare entry
• one to ten tare registers (numbered 0-9)
• identification number
• time
• date
• backlight
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-125SST. The test mode is cov-
ered in the User's Manual.
Use this mode to setup options and program the operation of the scale and
indicator. Configuration is explained fully in the Configuration Mode section
of this manual.
The WI-125SST can be sealed so no configuration items can be changed in
the configuration menu. Seal an LCD version by placing switch S1-1, located
inside the unit near the bottom corner of the PC board (see Figure 1), in the
OFF position. Unseal the unit by placing S1-1 in the ON
position. For both LCD and LED versions of the indicator,
while the indicator is powered, the state of the switch can
be changed at any time except while in the configuration
menu. If you change the state of the switch then, it WILL
NOT take affect until you exit the configuration menu.

The keyboard consists of 16 keys. Five keys, or buttons, provide all the
basic weighing functions:
• Tare
• G/N
• Zero
• Print
• Units
The other keys are used to access the menus for purposes of retrieving
information, testing the indicator, and configuring. The keyboard is shown
below:
Enters a pushbutton tare in gross/net operation. During data
entry this key is used to toggle between positive and nega-
tive values. Used to enter a dash (—) in ID numbers.
Accesses the gross weighing mode from any other function
and activates the net weighing mode if a tare is active.
Zeros the scale in gross or net weigh mode. This button
also clears keyed in digits on the display before they are
accepted.

number.
This section of the manual explains how to view and set up parameters in
the configuration mode. Follow the configuration menu and instructions in
Figure 2 to set up the WI-125SST 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.
1. While in Gross/Net Weighing Mode, enter the security code number
125.
2. With the number "125" displayed, press and hold the MENU key until
SET UP is displayed. NOTE: DO NOT let go of the MENU key until SET
UP is displayed or else TARE will be displayed. If this occurs, press the
G/N key to return to Weighing Mode and begin again at Step 1.
3. You are now in the Configuration Menu and may calibrate your system.
To move around within the Configuration Menu follow the instructions
printed on the following two pages. Details regarding specific param-
eters are provided on the following pages.
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 OFF (or into the sealed position). Next, enter the default
code number, 125. 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. Understand that opening the indicator
to access the switch unseals the indicator! Then enter a new code
number—twice, as the display prompts. Now you have complete access
to the configuration menu.

Dashes across the top of the
display indicate overload at
105% of capacity as a USA
standard.
Setup, Scale, Units-
Pounds, 1000g
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.
Setup, Scale, Units, Capacity-
Pounds, 1000g
This menu section lets you set the scale capacity for those units of
measure enabled under UNITS. This value equals the capacity plus
the overload tolerance.
Setup, Scale, Units, Capacity, Division-
Pounds, 1000g
This option lets you set the division size for the units of measure
enabled under UNITS.
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, 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, Zero, Stability-
Range, Delay
Range - 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.
Delay - Use this to specify the number of seconds during which the
weight must be within range (described above) before a no-motion
condition is displayed. Default value is 0.4 seconds.
Setup, Scale, Units, Capacity, Division, 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 opera-
tions (ON) or disable it (OFF). The gross weight must be zero for
AZT to work in net mode.

The default layout menu can be changed to suit your needs. Any of the
items can be deleted, added, or rearranged to accomplish this
customization.
The SELECT key opens up the next level of the menu under LAYOUT.
This information may be one of two types of items:
• an ASCII string or (user defined)
• a layout submenu (factory defined)
ASCII strings are stored under the ASCII layout print commands, such as
Nos. 1, 3, 5, 7, etc. (see Figure 4). 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 6 shows the ASCII string under the 1 ASCII layout print command
shown in Figure 5 . Table 1 shows the relationship between this se-
quence 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 layout
print command from the layout menu you first need to delete the entire
sequence of ASCII code numbers which are stored in that ASCII layout
print command.
As you enter ASCII code numbers, the display may read FULL when you
try to enter a code number. This means the memory allocated to the print
layout is full. You must rearrange or delete some of the items you want
printed for your customized printout.
Find complete instructions for these procedures in the section Examples
and Step by Step Instructions.
Under each non-ASCII layout print command (GROSS, TARE, etc.) is a
layout submenu. The layout submenu contains all seven layout print
commands and a DELETE command. From this submenu you select
what you want printed and in what order. The same submenu is available
in every case, but the currently selected item is always offered first. See
Figure 7.
To delete a layout print command: With the layout print command you
wish to delete on the display, press CLEAR.
