Inputs This test allows you to check the operation of the onboard and
optional inputs. Press the key to access the submenu.
Standard This submenu item lets you check the status of the onboard
inputs. In this example, 1000100, inputs #1 and #5 are active. The inputs are ordered 1-8 from left to right. A 1 means activated and a 0 means deactivated.
As you view the inputs, #8 is actually a flag that is dependent on the states of inputs 6 and 7. Input 6 resets flag #8 to a false 0. Input 7 sets flag #8 to a true 1. Input 8 does not terminate at a connector.
Option This menu item is available only if the option board is installed. It
works the same way as the Standard example above.
Voltages The submenu under VoltAgES lets you see the power supply
voltages. The voltage readings are updated 2 times per second.

Reset is very helpful if you get
confused and would like to put working values back in the WI-127 calibration menu.
Points See the section Calibrating the WI-127 for indepth instructions.
In this submenu you may view, edit, insert or delete calibration points in a list. The WI-127 allows calibration using up to five calibration points.
The WI-127 comes from the factory with two calibration points: 0 and 5000 lbs. (These weight values may differ depending on your unit of measure.)
These points may be calibrated in two ways: 1) by standard weight calibration or 2) by entering count values. Counts are calibrated to a 1 mV/V signal from the factory.
A 0 When you access the Points submenu the first item is A 0. This
stands for Apply 0 weight. This is the zero calibration point.
A 5000 The next calibration point in the default list is the calibration
point for full capacity. Your indicator is factory calibrated to 5000 lbs (1 mV/V). You may keep this value or key in a new value for full capacity.
Deadload Lets you view the count value for the current deadload. Press
the UNITS key to change the display to mV/V.
Display Shows the weight display without having to exit the menus. An
example of what is shown—d 5000. The d indicates a live display of weight and reminds you that the unit is in calibration. The value you see depends on the selected unit of measure, the calibration and the weight applied. The UNITS key works in this mode.
Reset Use this item to reset the calibration points to factory default
values. If you choose yES the values are set to 0 lbs at 0 mV/V and 5000 lbs at 1 mV/V.

110 Scale Menu
The next item in the 110 menu structure is Scale. In this group of submenus you set scale related parameters. Figure 9 shows the Scale menu.
Figure 9
110 Scale menu
Units This submenu lets you select what unit of measure will be
assigned to the three annunciators on the front panel.
Unit 1 The unit of measure you choose for this item will be assigned to
the annunciator labeled “lb” on the front panel. You can choose from the following list of units of measure:
Pounds = pounds 1000g = kilograms g = grams Oz = ounces Tons = tons Tonnes = tonnes (metric tons) None = no unit of measure is assigned.
Unit 2 The unit of measure you choose for this item will be assigned to
the annunciator labeled “kg” on the front panel. You can choose a unit of measure from the same list as above.
Unit 3 The unit of measure you choose for this item will be assigned to
the annunciator labeled “oz” on the front panel. You can choose a unit of measure from the same list as above.
11
Page 15
Don’t forget to re-calibrate your system after you change capacity.
Capacity The next scale menu item is capacity. Use this item to view or
edit the capacity of the unit in any unit of measure configured under Units. With CAPACity displayed, press the key. The current capacity is displayed. Use the numeric keypad to key in a new value and press to accept it and return to the CAPACity display.
You can view the capacity in other units of measure by pressing the UNITS key.
If you change capacity or division size in any unit of measure, this automatically changes all the other enabled units of measure as well.
If you want leading zeroes in your printouts or broadcast and autosend information, key in leading zeroes when setting division size.
To exit back to normal weighing mode, press the SELECT key and save changes as needed by pressing
ENTER with SAVE? displayed.
Division This selection allows you to view and edit the division size of the
enabled units of measure. You can enter any division size. The indicator will use the closest division size for each enabled unit of measure (1, 2 or 5 divisions).
You can view the division in other units of measure by pressing the UNITS key. The number is stored in the resolution you enter but is displayed in the closest valid division size.
Zero Use this menu item to set pushbutton zero related options.
Zero range is specified as a percent of capacity referenced from the deadload. There are two items in the submenu: -Range and
Range.
-Range Use this to set the negative range (below reference zero) within
which the unit may be zeroed. 100% is the default value.
Range Use this to set the positive range (above reference zero) within
which the unit may be zeroed. 100% is the default value.
Stable Use this menu item to set the motion detection parameters.
There are two items in the submenu: Range and Display.
Range Specifies the number of ±divisions for the motion window. Use
the numeric keypad to enter appropriate value. Most common settings are 0.5, 1, or 3 divisions.
A.Z.T. This stands for Automatic Zero Tracking. Range is the only item
Update Use this to set the display update rate from these choices:

Display Choose ON to if you want the display on while the indicator
senses scale motion. Choose OFF to blank the display while there is scale motion.
in this submenu.
Range Use this item to set the range within which the indicator will
automatically adjust the zero balance towards zero. Use the numeric keypad to enter appropriate value. Most common settings are 0.5, 1, or 3 divisions.
1 One update per second. 2 Two updates per second 5 Five updates per second 10 Ten updates per second.
Page 16
Average The next menu item is Average. This can be entered in one of
two methods: x disp. or x a-ds. Press the UNITS key to switch back and forth between the two choices.
The suggested method of setting the average is by picking a value for x disp. Doing this insures that a multiple of the display rate is always being averaged. This results in a steadier weight display.
Use x a-ds if you need an exact number of A-D conversions for your particular situation.
Changing the update rate changes the x disp. or x a-ds value based on the new update rate.
Harmonizer® filter is used only if the average value will not filter out the vibration by itself.
Values change with unit of measure.
x disp. 1 disp. is the default display when you access this item. x is the
number of display interval(s) over which the data is internally averaged prior to being displayed. The number of A-Ds averaged is based on the display update rate you set under the Update menu item. Default is 1 disp.
x a-ds x is the number of a-d conversions to average for each display.
The A-D weight conversion happens 60 times per second in this indicator. Average is the number of conversions you want to average for the weight that is displayed. Default is 12 a-ds when Update is at default of 5 and x disp. is at default value of 1.
Filter Use this menu item to configure the Harmonizer® filter settings.
Constant and Threshld are the two items you can configure in this submenu.
Constant This number represents the amount of filtering. Choose a setting
between 1 and 10. Choose 1 for the least amount of filtering but the fastest response. Choose 10 for the most filtering but the slowest response. Choose Off to disable the Harmonizer functions and default to the lowest filtering.
Threshld This is the window, in the current unit of measure, within which
weight changes are altered according to the constant. 10.0 is the default value shown in Figure 9. You should set the threshold value between 130 and 150% of the weight swings that need to be suppressed.
13
Page 17
Tips on setting up and using the Harmonizer® filtering
To find the best settings for your filter needs, follow the steps listed below.
1. What to Do: Determine the amount of positive and negative force exerted by the vibration on the scale.
How to Do It: Set Threshld to 0.0, Constant to OFF, and Average to
1.0 A-Ds. Return to weigh mode and observe the weight swings. Record the difference between the highest and lowest displayed weight values. Add 30 to 50% to this value. This is a good starting value for the Threshld setting. Do not set your indicator to this value until told to in step 7.
2. Setting the Average to higher values increases the filtering effect. What to Do: Set Threshld to 0.0, Constant to OFF and Average to
15.0 A-Ds. Check the stability of the scale. How to Do It: Save changes and exit to normal weight mode. Observe
the Center of Zero light. If it is on all the time your scale is stable within ¼ division. If the Center of Zero light blinks more filtering is required. Go to step 3.
3. Repeat step 2 but increase the Average by 15.0 A-Ds. Keep repeating steps 2 and 3 until the scale is stable or you’ve tried the entire range of Average (300 A-Ds). If the scale is still not stable go to step 4.
4. Setting the Constant to higher values increases the filtering effect. What to Do: Set Threshld to 0.0, Constant to 1.0 and Average to 300
A-Ds. Check the stability of the scale. How to Do It: Save changes and exit to normal weight mode. Observe
the Center of Zero light. If it is on all the time your scale is stable within ¼ division. If the Center of Zero light blinks more filtering is required. Go to step 5.
5. Repeat step 4 but increase the Constant by 1.0. Keep repeating steps 4 and 5 until the scale is stable or you’ve tried the entire range of Con­stant (10). If the scale is still not stable, decrease your display update rate and start over at step 1 using the new, slower display rate.
6. After the Constant value is established you may wish to lower the Average value to improve display response time.
7. After a final value for Constant and Average has been set, enter the Threshld value established in step 1. If this value is too small your scale will act as if the filtering is off or not working. Increase the Threshld value until your scale stabilizes.
14
If the Threshld value is too high your scale will react slowly to weight changes.
When Harmonizer is properly adjusted the scale will be stable at zero and will rapidly display a stable test weight value.

Code No. This item allows you to enter a personalized security code
number. Digits are not shown on the display as you key them in, so the display prompts you to enter the code number twice.
All & Phys. The two parameters in the SEAL menu are All and Phys. Below
are explanations of the choices you can make.
ALL set to YES Any time you access the setup menu and change any item in Table 1, the appropri-
ate counter increments one count. Changing multiple items on one visit to the menu increments the counter only one count. It's the number of visits with changes that are counted, not the number of changes per visit.
ALL set to NO With this setting the calibration internal counter will increment when you access
the setup menu and change any calibration item in Table 1. The internal configura­tion counter will increment only if you change one of the configuration items in bold print from Table 1.

Phys. set to Yes If Phys. is set to Yes, you must remove the physical seal (rear sealing plug) of the
WI-127 to access an internal switch. When you press this switch you have full editing privileges and the display shows the first item in the Service menu, About, without the need to enter the password.
If you enter the Service menu using the password and not the internal switch, you can change only the configuration items in Table 1 that are in normal, not bold, print.
PHYS set to NO
If PHYS. is set to NO, you can still press the internal switch and have instant setup menu access and editing privileges.
If PHYS. is set to NO, correct password entry is the only way to have editing privileges of all the items in Table 1 without breaking the physical seal. See note to left.
If the password is not entered correctly, the setup menu items can be viewed but not edited.

Be sure the correct capacity and division sizes have been selected before calibrating.
A step-by-step description of calibrating the WI-127 and using the Adjust menu can be found in the section titled Calibrating the WI-
127.
Below is the Adjust submenu for the 127. If the factory calibration has become corrupt, the word AdJUSt will flash on and off. To correct this you must send it to the factory. You may use the indicator under this condition by calibrating with real weights, not by entering previously recorded count values. See note at left.

In this submenu you may view, edit, insert or delete calibration points in a list. The WI-127 allows calibration using up to five calibration points.
The WI-127 comes from the factory with two calibration points: 0 and 5000 lbs. (These weight values may differ depending on your unit of measure.)
These points may be calibrated in two ways: 1) by standard weight calibration or 2) by entering count values. Counts are calibrated to a 1 mV/V signal from the factory.
A 0 When you access the Points submenu the first item is A 0. This
stands for Apply 0 weight. This is the zero calibration point.
A 5000 The next calibration point in the default list is the calibration
point for full capacity. Your indicator is factory calibrated to 5000 lbs (1 mV/V). You may keep this value or key in a new value for full capacity.
Deadload Lets you view the count value for the current deadload. Press
the UNITS key to change the display to mV/V.
Display Shows the weight display without having to exit the menus. An
example of what is shown—d 5000. The d indicates a live display of weight and reminds you that the unit is in calibration. The value you see depends on the selected unit of measure, the calibration and the weight applied. The UNITS key works in this mode.
Reset Use this item to reset the calibration points to factory default
values. If you choose yES the values are set to 0 lbs at 0 mV/V and 5000 lbs at 1 mV/V.
Print Use this item to print the calibration information shown in the
left column from port 1 by choosing yes. These numbers can be valuable if you have an indicator failure.

Units This submenu lets you select what unit of measure will be
assigned to the three annunciators on the front panel.
Unit 1 The unit of measure you choose for this item will be assigned to
the annunciator labeled “lb” on the front panel. You can choose from the following list of units of measure:
Pounds = pounds 1000g = kilograms g = grams Oz = ounces Tons = tons Tonnes = tonnes (metric tons) Other = This allows you to enter the information to create a
custom unit of measure. You need to enter the ratio values for the custom unit based upon another unit of measure and a string of text to use in serial output.
Under Basis choose the unit and amount upon which
the custom unit is based. Under Equals enter the equivalent custom unit value.
Page 26
Refer to the ASCII character chart located in the section Customizing the Serial Output.
Example 1: To create a ‘stone’ unit of measure, the
Basis would be 14 pounds and Equals should be 1 stone.
Example 2: To create an ounce unit of measure, the
Basis would be 1 pound and Equals should be 16 ounces.
Example 3: To create a kg unit of measure, the Basis
would be 10 pounds and Equals should be 4.5359237 kilograms. Ten pounds is used so all eight digits can be entered as the Equals value.
Under Label you create the serial label for the custom
unit of measure. With the first ASCII value displayed you can use the keys to do the following:
ENTER key- accepts the displayed value and
returns to Label display.
Custom label can be a maximum of 16 characters in length.
MENU key - accepts the displayed value and moves
to the next ASCII character value.
ESCAPE key - exits the display without making a
change.
+/- key - Inserts a new ASCII value before the
currently displayed ASCII value. Key in the ASCII value and continue by pressing another key.
ZERO key - deletes the currently displayed ASCII
value.
Continue editing, inserting, and deleting until you are
done. Press to exit the label entry.
None = no unit of measure is assigned.
Unit 2 The unit of measure you choose for this item will be assigned to
the annunciator labeled “kg” on the front panel. You can choose a unit of measure from the same list as above.
Unit 3 The unit of measure you choose for this item will be assigned to
the annunciator labeled “oz” on the front panel. You can choose a unit of measure from the same list as above.
Don’t forget to re-calibrate your system after you change capacity.
Capacity The next scale menu item is capacity. Use this item to view or
edit the capacity of the unit in any unit of measure configured under Units. With CAPACity displayed, press the key. The current capacity is displayed. Use the numeric keypad to key in a new value and press to accept it and return to the CAPACity display.
You can view the capacity in other units of measure by pressing the UNITS key. The number is stored in the resolution you enter but is displayed in the division size stored in Division.
23
Page 27
If you change capacity or division size in any unit of measure, this automatically changes all the other enabled units of measure as well.
Division This selection allows you to view and edit the division size of the
enabled units of measure. You can enter any division size. The indicator will use the closest division size for each enabled unit of measure.
If you want leading zeroes in your printouts or broadcast and autosend information, key in leading zeroes when setting division size.
This feature keeps the indicator from functioning at power up in an unstable environment.
You can view the division in other units of measure by pressing the UNITS key. The number is stored in the resolution you enter but is displayed in the closest valid division size. Any additional resolution is used in calculating division size in the other units of measure.
Zero Use this menu item to set zero related options. Zero range is
specified as a percent of capacity referenced from the deadload. There are three items in the submenu: -Range, Range and
Start.
-Range Use this to set the negative range (below reference zero) within
which the unit may be zeroed. 100% is the default value.
Range Use this to set the positive range (above reference zero) within
which the unit may be zeroed. 100% is the default value.
Start Use this parameter to determine whether or not the indicator
must reach a stable reading within the above range before it will exit the start-up sequence, automatically zero the scale and begin weighing. While trying to acquire a stable zero the unit displays Auto. 0. Select No if you want no start-up zero restrictions. Choose Yes if you want the start-up zero restriction.
To exit back to normal weighing mode, press the SELECT key and save changes as needed by pressing
ENTER with SAVE? displayed.
Stable Use this menu item to set the motion detection parameters.
There are three items in the submenu: Range, Delay and Display.
Range Use this to specify the number of ±divisions for the motion
window. Default is 1.0 division.
Delay Use this to specify the number of seconds during which the
weight must be within range (described above) before a no­motion condition is displayed. Default value is 0.4 seconds.
Display Choose ON to if you want the display on while the indicator
senses scale motion. Choose OFF to blank the display while there is scale motion. Default is ON.
A.Z.T. This stands for Automatic Zero Tracking. There are two items in
this submenu; Range and Net.
Range A.Z.T. adjusts the zero balance towards zero at the rate of .1
divisions per second after being within the range given for at least 2 seconds.
Net You may also enable or disable automatic zero tracking of net
weight.
Update Use this to set the display update rate from these choices:
24
1 One update per second. 2 Two updates per second 5 Five updates per second 10 Ten updates per second.
Page 28
Changing the update rate changes the x disp. or x a-ds value based on the new update rate.
Average The next menu item is Average. This can be entered in one of
two methods: x disp. or x a-ds. Press the UNITS key to switch back and forth between the two choices.
The suggested method of setting the average is by picking a value for x disp. Doing this insures that a multiple of the display rate is always being averaged. This results in a steadier weight display.
Use x a-ds if you need an exact number of A-D conversions for your particular situation.
x disp. 1 disp. is the default display when you access this item. x is the
number of display interval(s) over which the data is internally averaged prior to being displayed. The number of A-Ds averaged is based on the display update rate you set under the Update menu item. Default is 1 disp.
x a-ds x is the number of a-d conversions to average for each display.
The A-D weight conversion happens 60 times per second in this indicator. Average is the number of conversions you want to average for the weight that is displayed. Default is 12 a-ds when Update is at default of 5 and x disp. is at default value of 1.
Harmonizer® filter is used only if the average value will not filter out the vibration by itself. See Tips on
setting up and using the Harmonizer filtering on the next
page.
Values change with unit of measure.
When using overload or over capacity alone, set the other menu item to its maximum value to disable any conflicts.
Filter Use this menu item to configure the Harmonizer filter settings.
Constant and Threshld are the two items you can configure in this submenu.
Constant This number represents the amount of filtering. Choose a setting
between 1 and 10. Choose 1 for the least amount of filtering but the fastest response. Choose 10 for the most filtering but the slowest response. Choose Off to disable the Harmonizer functions and default to the lowest filtering.
Threshld This is the window, in the current unit of measure, within which
weight changes are altered according to the constant. 10.0 is the default value shown in Figure 15. You should set the threshold value between 130 and 150% of the total weight oscillations that need to be suppressed. If weight changes are +20 lbs and -10 lbs, set this value to 130 to 150% of 30 lbs.
Over This submenu lets you setup the overload and capacity setting
which cause the O. load error message.
Overload This value is expressed as a percent of capacity referenced from
the deadload determined by calibration. Overload is restricted to 200% or lower. 105% is the default value.
Over Cap. This value expressed as a number of divisions over the capacity
referenced from the zero value. A value of 9 satisfies UK requirements. Configurable from 0 to 999999 divisions. Default is 9 divisions.

Page 29
Tips on setting up and using the Harmonizer® filtering
To find the best settings for your filter needs, follow the steps listed below.
1. What to Do: Determine the amount of positive and negative force exerted by the vibration on the scale.
How to Do It: Set Threshld to 0.0, Constant to OFF, and Average to
1.0 A-Ds. Return to weigh mode and observe the weight swings. Record the difference between the highest and lowest displayed weight values. Add 30 to 50% to this value. This is a good starting value for the Threshld setting. Do not set your indicator to this value until told to in step 7.
2. Setting the Average to higher values increases the filtering effect. What to Do: Set Threshld to 0.0, Constant to OFF and Average to
15.0 A-Ds. Check the stability of the scale. How to Do It: Save changes and exit to normal weight mode. Observe
the Center of Zero light. If it is on all the time your scale is stable within ¼ division. If the Center of Zero light blinks more filtering is required. Go to step 3.
3. Repeat step 2 but increase the Average by 15.0 A-Ds. Keep repeating steps 2 and 3 until the scale is stable or you’ve tried the entire range of Average (300 A-Ds). If the scale is still not stable go to step 4.
4. Setting the Constant to higher values increases the filtering effect. What to Do: Set Threshld to 0.0, Constant to 1.0 and Average to 300
A-Ds. Check the stability of the scale. How to Do It: Save changes and exit to normal weight mode. Observe
the Center of Zero light. If it is on all the time your scale is stable within ¼ division. If the Center of Zero light blinks more filtering is required. Go to step 5.
5. Repeat step 4 but increase the Constant by 1.0. Keep repeating steps 4 and 5 until the scale is stable or you’ve tried the entire range of Con­stant (10). If the scale is still not stable, decrease your display update rate and start over at step 1 using the new, slower display rate.
6. After the Constant value is established you may wish to lower the Average value to improve display response time.
7. After a final value for Constant and Average has been set, enter the Threshld value established in step 1. If this value is too small your scale will act as if the filtering is off or not working. Increase the Threshld value until your scale stabilizes.
26
If the Threshld value is too high your scale will react slowly to weight changes.
When Harmonizer is properly adjusted the scale will be stable at zero and will rapidly display a stable test weight value.

Define Refer to the section “Customizing your Serial Output”
for detailed instructions about this submenu.
The Define submenu allows you to customize printouts, build ASCII strings, create groups and enable continuous send.
ASCII The WI-127 can store up to sixteen ASCII strings, each contain-
ing up to 32 individual ASCII characters. The WI-127 contains one default ASCII string. You may customize this string as well as build fifteen additional ones.
Layouts The WI-127 has sixteen available print layouts (of which eight
have default settings) which may include a combination of sixteen items. Build your custom layouts by choosing among nineteen print items, including ASCII strings, weight values, time and date, and other layouts.
Groups Here is where you specify which ports will print which layouts. A
total of nine groups is available. Within each group, up to three ports can output layouts. Port 1 is standard; ports 2 & 3 are offered only if additional serial boards are installed. Each port is then assigned a layout to print.
Broadcast Enables or disables continuous send. To enable continuous send,
a group number must be entered under GrouP. This number defines the group to be activated at each display update.
Autosend Enables or disables autosend. To enable auto send, a group
number must be entered under GrouP. This number defines the group to be printed each time weight stabilizes above 1% capacity. The weight must fall below 1% capacity for the indicator to initiate another print.
29
Page 33
Except for Reply the actions at right can only be executed if the character is received while the indicator is in the Display mode.
Protocol A protocol is defined as the set of input characters assigned to specific
actions for each port. Under this item you choose a port, choose an input number, assign an ASCII character (decimal value) to the action, and choose the associated response or action from the following list (see note at left):
Print - Causes a Print to occur. You can specify which group to
output.
Reply - Causes a Print to occur. You can specify which group to
output. This runs as a background fuction without regard for motion. Reply can be executed when the indicator is in Display mode and also in the User Menu.
Zero - Performs a Zero function. None - Assigns no function. Units - Switches indicator to the next available unit of measure. Unit 1 - Switches indicator to Unit 1, if available. Unit 2 - Switches indicator to Unit 2, if available. Unit 3 - Switches indicator to Unit 3, if available. Select - Switches indicator to next available display mode. Gross - Switches display to the gross mode. Net - Switches display to the net mode. Tare - Switches display to the tare mode. P.B.Tare - Causes a pushbutton tare operation.
Example: This is how you would set up the indicator if you want to zero the
scale through a serial port from a computer or PLC: Select a port (1, 2 or 3) under Protocol. Connect a cable between this port and your computer or PLC. Configure a serial Input to perform an action. A maximum of 16
serial inputs may be configured. Under the selected input, under Ch (Channel), choose an ASCII
character, for example Z, represented by decimal value 90. See Table 5 in the WI-127 Service Manual for a complete list of ASCII charac­ters.
30
Go over from Ch to Action. Under Action drop down and select Zero from the menu choices.
Now when you send a Z from your PC or PLC to the serial port, this will cause the display to zero out, the same as if you pressed the front panel ZERO key.

Calibrating the WI-127
The WI-127 allows calibration using up to five calibration points. These points can be any weight value in any unit of measure. Standard calibration generally uses two calibration points; for linearization, more than two may be used.
The WI-127 comes from the factory with two calibration points: 0 and 5000 lbs. (These weight values may differ depending on your unit of measure.) To perform
Any changes you make within the calibration menu will be immediately implemented, so take care when recalibrating your system.
While in the Calibration menu, you may print the calibration data out of port #1 by selecting YES. See sample below.

linearization, you can insert more calibration points (up to a total of five points). These points appear in a list and may be inserted and deleted. The unit will order the points based on increasing count values.
These points may be calibrated in two ways: 1) by standard weight calibration or
2) by entering count values. Counts are calibrated to a 1 mV/V signal from the factory. This allows you to view the deadload, calibration point counts, and loadcell test in our standard count value (200,000 counts per mV/V) or press UNITS to view and edit the real mV/V. There are benefits to this feature:
•You can enter these values into a new indicator hooked up to the same scale. This is useful if the old indicator needs servicing and a quick turnaround is needed.
•Another benefit is the ability to enter the profile of a weight sensor without having to calibrate the indicator conventionally. This profile is used mostly in batching bars and force measurement devices, which have a standard or known output and are more difficult to calibrate in the field.

Use the key to move down the list of printable items in Table 3. Use the key move
up the list.
Just as in other Weigh-Tronix indicators (WI-125, WI-150, etc.) the layouts within the WI-127 may be customized. If the nine default layouts do not fit your specific applications, or if you wish to include, for example, custom wording, you may easily customize a print layout. This is done within the “Options” menu of the service menu. See the section Step by Step Instructions / Entering the Define Submenu located just before Figure 24. But please read the following section in order to understand what items are available for customization.
The WI-127’s layouts can be a maximum of sixteen items long. Any combination of the following nineteen items (up to sixteen maximum) may be used to form a
layout. These printable items, along with their descriptions, are listed below.
Table 3: Layout Print Items (Blocks)
Print Items Description
Status byte = 8 bits Transmitted as a single character.
The bits appear as follows: 0011LEBM L has a weighted value of 8 E has a weighted value of 4 B has a weighted value of 2 M has a weighted value of 1
where L is set to logic 1 when a Low voltage condition exists; logic 0 otherwise. E is set to 1 when an a-d Error condition exists; 0 otherwise. B is 1 when the weight is beyond displayable range (over- or under­capacity); 0 otherwise. And M is set to logic 1 when an in-motion condition exists; set to logic 0 when the weight is stable. The upper four bits are set to 0011 to cause the value to be printed as a digit or symbol in row 3 of the ASCII character set.
These are the most common charac­ters you will see on a terminal: “0” = Stable “1” = In-motion “2” = Range error “4” = A-D error “8” = Low voltage
END and DELAY are not printable items.
GROSS Gross weight is transmitted. NET Net weight is transmitted. DISPLAY Current displayed live weight is transmitted (gross or net),
depending on the current display mode. TARE Current tare (general or numbered register) is transmitted. T. REG Current tare register number is transmitted (a space is
transmitted for the general tare register). SELECTED Currently selected item from the select list is transmitted
(gross, tare or net). ID Identification number is transmitted. HOUR Current time is transmitted. DAY Current date is transmitted. STATUS Current status is transmitted. See note at left.
* LABEL Weight label is transmitted. Five choices are available:
• gross-outputs the gross label
• net-outputs the net label
• display-outputs gross or net depending on the displayed live weight
• tare-outputs the tare label
• selected-outputs the label gross, tare or net following SELECTED item
UNITS Unit of measure label is transmitted
* LAYOUT A predefined layout may be included within another layout.
For example, Layout 6 includes Layouts 1, 2, & 3. Note: A “layout error” will occur if a layout uses its own layout within itself or if a “loop” of layouts is used (for example, Layout 1 cannot use Layout 2 if Layout 2 includes Layout 1)
* DELAY Pauses serial port output by this many seconds (0-255)
END Insert to delete any printable items that follow * ASCII A configurable ASCII string can be inserted and transmitted * Ch. A character (ASCII value) can be entered to be transmitted * SPACES A configurable number of spaces is transmitted * CRS A configurable number of carriage returns is transmitted * LFS A configurable number of line feeds is transmitted
FF A form feed is transmitted
44
* denotes items that require detailed information. For example: if “LABEL” is
inserted within a layout, you must specify the label to be printed; if “SP” is
inserted, you must specify the number of spaces to be transmitted.

ASCII Strings
As mentioned in the previous section, the layouts may include a number of items, one of which is ASCII strings. These ASCII strings allow you to customize your printouts with custom wording.
ASCII is an acronym for American Standard Code for Information Interchange. ASCII codes are simply numbers (code values) a computer can translate into letters, numbers and actions.
The WI-127 can store up to sixteen ASCII strings, each containing up to 32 individual characters. These strings are numbered 1-16. Below is a worksheet to help define several ASCII strings. Write in your custom wording in the white boxes, then convert the characters to ASCII code values using the table on the next page. Write these values in the gray boxes. If a letter or action is repeated several times, place a decimal point after the code value, then insert the number of times it is to be repeated. For example, 13.3 means three successive carriage returns.
The WI-127 contains one default ASCII string. String #1 will spell out “WEIGH­TRONIX WI-127” when added to a customized layout. Feel free to fill in the worksheet below to keep track of your custom defined ASCII strings.
Complete instructions for programming these ASCII strings into the WI-127 can be found in the section Step by Step Instructions preceding Figure 24.

A group is the combination of your layout and the assigned serial port through which the data is sent. The Groups submenu is where you specify which ports will print which layouts.
A total of nine groups is available. Within each group, up to three ports can output layouts. Port one is standard; ports 2 & 3 are offered only if additional serial boards are installed. Each port is then assigned a layout to print.
The default for the PRINT key is Group 2.
You may print other groups by keying in the correct group number, then pressing PRINT. Note: This option must be enabled in the service menu first.
The default group settings are: Group 1: Port 1 prints Layout 5 Group 2: Port 1 prints Layout 6 Group 3: Port 1 prints Layout 7 Group 4: Port 1 prints Layout 8
Here are two examples of how the groups might be set up using three serial ports: Group 1: Port 1 prints Layout 1 Group 2: Port 1 prints Layout 5
Port 2 prints Layout 2 Port 2 prints nothing Port 3 prints Layout 3 Port 3 prints Layout 2
Follow the instructions below to set up your groups.

WI-127 Inbound/Outbound Serial Communications
Serial communication in the WI-127 involves layouts, ASCII strings, and groups. Their relationship is this: The ASCII strings allow entry of alpha-numeric charac- ters that can be assigned to a layout; the layouts contain the information sent out each port; and the groups set up each port and what is transmitted from it.
The WI-127 Inbound/Outbound indicator has a total of 32 available print layouts.
Layouts
These layouts replace the sixteen found in the standard WI-127. Twenty-nine of these layouts are predefined. You may use them as they are, or you
may customize them to fit your particular application. Six of these layouts are used as defaults. Below you will find examples of these
regularly used default printouts. Note that the layouts use other layouts within themselves (see the italics to the right of each element of the printouts). This allows for a high degree of customization. You will find all the predefined layouts mapped out on the following pages.

Layout items
Print layouts are constructed using various elements including ASCII strings/ characters, print items, and other layouts. Following are 16 print items which have been added to the WI-127 Inbound/Outbound indicator. The standard WI-127 has 19 items. Adding these 16, you will have a total of 35 items with which to build print layouts.These items are found in the “Layouts” section of the Options Sub­Menu of the Service Menu.
As you scroll through the list of items, you will find the following new items:
Print Items Description Channel Currently selected inbound/outbound channel is transmitted. Hour inTime of the inbound/outbound weighment for the currently selected
channel is transmitted.
Day in Date of the inbound/outbound weighment for the currently
selected channel is transmitted.
Inbound Inbound weight for the currently selected channel is transmitted. Ch Gross Inbound/outbound gross weight for the currently compleyed
transaction is transmitted.
Ch Tare Inbound/outbound tare weight for the currently completed
transaction is transmitted.
Ch Net Inbound/outbound net weight for the currently completed
transaction is transmitted.
Ch Total Inbound/outbound net accumulator value for the currently
selected channel is transmitted.
Ch Count Inbound/outbound transaction counter value for the currently
selected channel is transmitted.
Register Currently selected tare register number is transmitted. Rg Type Source of the tare weight for the currently selected tare register
is transmitted. The two default values are “Pb” (pushbutton) and “KP” (keypad).
Rg Total Net accumulator value for the currently selected tare register is
transmitted.
Rg Count Transaction counter value for the currently selected tare
register is transmitted.
nn By Ch “Layout nn” is used once for every inbound/outbound channel in
existence, in ascending order. This supports the ability to generate inbound/outbound database reports.
nn By In “Layout nn” is used once for every inbound/outbound channel
that has an inbound weight, in ascending order. This supports the ability to generate inbound/outbound database reports.
nn By Rg “Layout nn” is used once for every tare register in existence, in
ascending order. This supports the ability to generate tare database reports.

ASCII strings
As mentioned in the previous section, layouts may include a number of elements, on of which is ASCII strings. These ASCII strings allow you to customize your printouts with custom wording.
The WI-127 Inbound/Outbound can store up to sixteen ASCII strings, each containing up to 32 individuals characters. These strings are numbered 1-16.
The WI-127 Inbound/Outbound contains 15 default ASCII strings. Below is a table containing the 15 default strings. Use these, or develop your own custom mes­sages.

Page 69
Printing Groups
In order to print, the layouts in the WI-127 are assigned to groups. These groups are in turn assigned to specific serial ports. A group may contain several layouts or only one layout.
Each group can have up to three serial ports. Each port can have a different layout assigned to it. Port #1 is always the onboard seril port; ports #2 and #3 are add­on option cards.
The default group settings in the WI-127 are as follows:
Group # Port 1 Port 2 Port 3 Inhibit
1 Layout 1 None None Yes 2 Layout 25 None None Yes 3 Layout 26 None None Yes 4 Layout 27 None None Yes 5 Layout 28 None None No 6 Layout 29 None None No
Each group can be printed separately by using the “N print” feature under “Print” in the set-up menu. The operator presses the number of the group before pressing the PRINT key. The information assigned to that group number will be printed. Pressing 1 and PRINT will print group #1, pressing 2 and PRINT will print group #2, etc.

WI-127 In-Motion Software
This section of the WI-127 Service manual covers the optional in-motion software for Conveyor/Monorail scales. This software has the following additions made to the service menus. The complete service menus are included at the end of this section. Below are descriptions of each additional item.
Conveyor (After Define in the Options menu)
Tare ( After Conveyor in the Options menu)
No Choose this if you want the indicator to operate as normal. The inputs
used for in-motion weighing are ignored. The cutoffs, analog output, B.C.D. output, and displayed weight, all work as normal.
Yes Choose this to use the indicator for in-motion weighing. The indicator
uses the built in reset/set inputs to start and stop averaging weight readings. An in-motion weighment is the average of all these weight readings. Every time an in-motion weighment is calculated, the indicator does the following:
Updates the Gross and Net variables with the new weighment Updates the Cutoff outputs, Checkweighing outputs, B.C.D. output and
the Analog output for the new weight Triggers an auto-print, if enabled Displays the new weighment for 7 seconds or until the next weighment
begins (dashes) or an error occurs.
It is always possible to enter tare to any resolution but this selection determines how gross, tare, and net are displayed, printed, and calculated.
0.1 d* The net weight is calculated internally to 10 times the resolution, but
displayed and printed to the nearest division. Tare values are printed and displayed at 0.1 division.
Default Setup Modifications

Autoprint
While in the in-motion mode, autoprint changes functionality to automatically print each time an in-motion weighment is made through the in-motion logic. The default group for Autoprint is 1. (Displayed weight) While in in-motion mode, the autoprint functions in the background.
Cutoffs/Checkweigh
While in the in-motion mode, the cutoffs and over/under/accept outputs are only updated as each in-motion weighment is made. The outputs follow the displayed in-motion weighments (gross or net) If an erroneous in-motion weighment is made, the outputs drop out until the next valid weighment is made.
Analog output/B.C.D. output
The weight output cards follow the in-motion weighments while in the in-motion mode. As usual configuration determines whether to follow the gross, net, or displayed weighments.
Dynamic Weighment Serial Output
The Gross and Net weights in the layout menus follow the in-motion weighments while in the in-motion modes. Each time the indicator calculates a new average, the gross and net weights are calculated based on the new weighment. The gross and net change from the last In-motion weighment value when the indicator returns to live weight display. Dashes are printed if ‘no’ is selected for ‘inhibited’ for that group and dashes are on the display to indicate in-motion sampling.

If the indicator is in a user menu or editing a register, these display modes do not appear on the display. In this case the in-motion operations appear to occur in the background.
- - - - - - - -
This indicates that the indicator is sampling the current item on the scale. As soon as the sampling is completed, the weight is calculated and displayed.
Annunciator 5 (ID)
This annunciator is used to indicate that the display is showing the current in-motion weighment. This display appears for seven seconds after each in-motion weighment is calculated. This mode can be interrupted by a new weighment (dashes).
Weighing
Errors
Sampling occurs from leading edge to trailing edge of the reset/set input. The leading edge must correspond to the weight being entirely on the live rail, and the trailing edge must correspond to the weight just ready to begin leaving the live rail.
1) Six seconds maximum are allowed from arrival to exit. This supports a 12 inch package at a minimum speed of 30 ft/min on a 4 ft conveyor scale. If 6 seconds elapse, an error message is displayed, and auto-print is not initiated. The error message persists until a new weighment is begun, but no longer than 7 seconds (unless retriggered by a subsequent weighment.) After 7 seconds, the display reverts to live weight.
2) At least two samples are required to be accumulated to consider a weighment to be valid. This corresponds to 1/30 th of a second (or 1/10 ft at 180 ft/min). This requirement is violated when boxes are too long or a conveyor is moving too fast. If less than 2 samples are accumulated, the weighment is considered to be in error and is handled in the same manner as (1) above.
3) Weighments less than the upper limit of the AZT window are considered to be in error and are handled in the same manner as (1) above.
WI-127 to Conveyor and Monorail Wiring Information
The wiring information to connect a WI-127 indicator to a CVC/CVCS conveyor scale or in-motion monorail scale is as follows:
Photocell J-box Wire Color WI-127 Function (conveyor only) (Conv.) (Mono)
TB1-2 White White TB15-8 Set input (exit trigger) TB1-3 Red NA TB14-1 +22 VDC Power TB1-4 Black Black TB15-9 Logic Gnd TB1-5 Green Red TB15-7 Reset input (entrance trigger)

Page 82
In-Motion Conveyor Miscellaneous Information
The WI-127 would need to have the special in-motion software installed to be compatible with the CVC operation. The recommended filter settings for the in­motion operation is a Filter time constant of 3 and a threshold equal to full scale capacity. The in motion system will only weigh and transmit data properly if there is only one package on the scale at a time. With packages identical in size, this means front edge to front edge spacing of at least the length of the conveyor. With varying length package applications there are two criteria which must be met:
1) With a package on the conveyor scale, the next one coming on the scale must not break the entrance photocell beam prior to the one on the scale breaking the exit beam.
2) With a package on the conveyor scale, the exiting package must clear the exit beam prior to the package entering the scale clearing the entrance beam.
If either of these rules are violated erroneous weights may be transmitted or weight values not transmitted at all.
This simple formula will help you figure the minimum package spacing needed for unequal package sizes.
The diagram below shows a formula for figuring throughput of identically sized packages.
