Avery Weigh-Tronix WI-125 SST indicator User’s Manual
The WI-125 SST is a full featured indicator in a stainless steel enclosure and includes a numeric keypad. It can be used for a variety of weighing applications, including gross weighing, net weighing, and tare weighing. The indicator also features a single channel accumulator that can be used to track the total weight of multiple loads. It can also be used to control cutoffs for a variety of applications, such as ingredient weighing and setpoint weighing. The WI-125 SST also features an RS-232 output for data transmission to a peripheral device.

Operations Mode
This manual is valid for Rev. F or higher software.
Operations mode contains all normal weighing operations. In this mode you can view or set the following parameters if the unit is so configured:
• push-button tare
• quick keypad tare entry
• one to ten tare registers (numbered 0-9)
• identification number
• time
• date
• backlight (LCD version only)
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 unless you enter the security code.

Entering Cutoff Values
Through the Front Panel
Follow the steps below to enter a cutoff value. The cutoff output will be ON below the value entered and OFF equal to or over the value entered.
1.
Push the MENU key until
Cutoffs is displayed.
Cutoffs 0 to 7 are displayed.
2.
Push the SELECT key. . .
3.
Push the MENU key to scroll through the cutoff channels.
4.
Use the numeric keypad to enter the cutoff values then press the
MENU or SELECT key.
Controlling Cutoffs
Some menu items may not appear in your particular situation due to configuration setup or firmware revision level.
The WI-125 Indicator allows you to control the cutoff process from the front panel. Through the WI-125 you may: enable/disable the cutoff process, continue or interrupt the operation of a cutoff before its setpoint has been reached, and/or terminate the process at any time before the last cutoff has been reached.
There are two types of cutoffs in the WI-125: the ingredient cutoff and the setpoint cutoff (default). With ingredient cutoffs, you tell the indicator the weight of each ingredient you want and the indicator will call for that much of each ingredient, no matter what the weight display says. If you want 100 pounds of ingredient #1 and 100 pounds of ingredient #2, you would enter 100 for cutoff #0 and 100 for cutoff #1.
With setpoint cutoffs, you tell the indicator at what weight display you want the cutoffs to activate. In other words, if you want 100 pounds of ingredient
#1 and 200 pounds of ingredient #2, you would set the first setpoint cutoff at
100 and the second cutoff at 300 pounds because that is what the weight display will read when you want the actions to occur.
You can tell which kind has been configured in your indicator by looking at the cutoff number in the Operations menu shown below. If the cutoff number has a decimal point following it, the cutoff is a setpoint type. If there is no decimal, it is configured as an ingredient type.

Single Accumulator with Counter
Weighing and Printing
Printing the accumulated weight and count can be accomplished at any time during the weighing process;
however, printing these values automatically clears
them from memory! So take care to print the accumulated values only after you have made all the necessary weighments.
There is a single channel accumulator in both the LED and LCD model indicators. The accumulator will add the displayed weights automatically and print individual weights and totals on command.

Transmitting Data
RS-232 Output
Communication protocol
The WI-125 SST provides an RS-232 output for data transmission to a peripheral device. Refer to the Service Manual for RS-232 interface connections.
To transmit data, follow these instructions:
If your indicator has a peripheral device connected, from the gross/net weighing mode press the PRINT key to transmit the selected output(s).
The PRINT annunciator (See Figure
2) will illuminate while data is transmitted and the data configured to be printed will be output to the printer. See Figure 5 for a sample printout.
Samples of the default printout for a WI-125 SST are shown in Figure 5.
This is the displayed weight (Gross or Net) followed by a carriage return and line feed.
An enquire code can be sent to the WI-125 SST. This will prompt the indicator to send a standard printout. The default enquire code number is an
ASCII decimal 005. This number can be changed in configuration.
