4.8 Animal Weighing Using AUTO-LOC Feature
The Model 640 has a feature called AUTO-LOC. It is specifically designed for use in
weighing livestock. Once the indicator has determined the animal’s weight, the
indicator display automatically locks on that weight. The weight reading will not change
as long as the animal is on the scale. This makes the weight easy to record since the
numbers are not rapidly changing as the animal moves on the scale.
AUTO accumulate feature can be turned on or off to work with AUTO-LOC. Refer to
Figure 8.3 Table for 5th CCN Digit on page 55 to choose a 5th digit of the CCN which
will turn on the accumulator.
There are two modes in the Auto–LOC feature:
Model 640 Indicator Series User Instructions 37
4 Weighing Procedures
Standard LOC Mode
In standard mode, an animal’s weight is locked on the display until the animal leaves
the scale.
Advanced LOC Mode
In advanced mode, an animal’s weight is locked on the display until the next animal
comes onto the scale.
4.8.1 How to Set Up AUTO-LOC
Follow these steps to set up the AUTO-LOC feature:
1. Access the Setup menu from the G/N mode. Press and hold the HOLD/MENU
key for three beeps (3 seconds), then release…

4.8 Animal Weighing Using AUTO-LOC Feature
7. Press the HOLD/MENU key several times until…
AUT.LOC appears. The AUTO-LOC menu selection only shows up when
a configuration code number turns on this feature.
This menu item is where you choose standard or advanced LOCK,
minimum weight (MIN.WT), and release tolerance (REL.TOL)
appropriate for the livestock application.
8. Press the PRINT/SELECT key…
MODE is displayed.
9. Press the PRINT/SELECT key…
STD.LOC is displayed. This is the standard LOCK. Toggle between this
and the ADV.LOC by pressing the HOLD/MENU key.
10. When your choice is displayed, press the PRINT/SELECT key…
Your choice is selected and MODE is displayed.
11. Press the HOLD/MENU key…
MIN.WT is displayed. This is where you set the minimum weight that
must be on the scale to activate the AUTO-LOC feature. This prevents
smaller weights from locking on the display. See the example below.
EXAMPLE: If you are weighing 1200 pound cattle, you may set the minimum weight
at 800 pounds and a release tolerance of 25%. Anything thing that goes on the scale
that weighs less than 800 pounds (like a person or the neighborhood dog) will not
cause the weight to lock. When an animal steps off the scale and the weight drops by
at least 300 pounds (25% of 1,200 pounds), the system will reset to lock on the next
weight above 800 pounds.
12. To set the minimum weight, press the PRINT/SELECT key…
Use the numeric entry procedure to enter the minimum weight value.
13. When the value is entered, press the PRINT/SELECT key to accept it and…
MIN.WT is displayed.
14. Press the HOLD/MENU key…
REL.TOL is displayed. This is the release tolerance. This is set in steps
12 and 13 which must be removed from the scale before the AUTO-LOC
resets. See example in the left margin of page 39.
15. Press the PRINT/SELECT key…
Use the numeric entry procedure to enter the release tolerance in
percentage of the minimum weight.
16. When the value is entered, press the PRINT/SELECT key to accept it and…
Model 640 Indicator Series User Instructions 39
Your choice is selected and REL.TOL is displayed.
4 Weighing Procedures
You can exit the menu and return to normal weighing mode by repeatedly pressing the
G/N key. If, during operation the AUTO-LOC feature seems very slow, this can be due
to excessive weight fluctuations. In this case you can access the Setup menu and
increase the FILTER-CONSTANT parameter until it works properly. Reference How to
Configure Filtering on page 60 for instructions on adjusting the filtering.
4.8.2 Weighing Individual Animals with Standard Mode AUTO-LOC
The following describes how a Model 640 can be used for weighing and recording an
animal’s weight automatically on a single animal livestock scale with standard mode
AUTO-LOC. Unit must be setup for AUTO-LOC and set for standard (STD.LOC) mode.
1. Turn indicator on, press the G/N key to access the gross mode and press the
ZERO key…
0 is displayed.
2. Move animal onto the scale…
L WWWW is shown
WWWW = animals auto-locked weight
If a false locked weight occurred, press ZERO/CLEAR to recheck the
animals weight. This will also delete from the accumulators the last
locked-on weight and replace it with the new locked-on weight.
If auto-accumulate is on, once the weight is locked-on, the Model 640
will automatically accumulate to the last selected memory channel.
Weight stays locked until the weight on the scale drops by the
programmed release tolerance. (Example: weighing a 2000 lb animal
with a 25% release tolerance, means the lock will release when weight
drops below 1500 lb).
If the animal is released and the weight falls below the tolerance it may
be possible to lock on another weighment. We recommend putting in a
high release tolerance like 75% to insure reliable operation.
Also to prevent an inadvertent AUTO-LOC if someone leans/steps on
the scale, we recommend putting in a large amount for the MIN.WT
parameter to prevent this from occurring. (EX: 300 lb)
3. Remove the animal from the scale…
Scale returns to live weighing mode
4. Repeat steps 2 and 3.
4.8.3 Weighing Individual Animals with Advanced Mode AUTO-LOC
The following describes how a Model 640 can be used for weighing and recording
animal’s weight automatically on a single animal livestock scale using the advanced
AUTO-LOC mode. The indicator must be setup for AUTO-LOC and set for advanced
(ADV.LOC) mode. In addition, the auto-accumulate feature can be turned on or off.
40 Model 640 Indicator Series User Instructions
4.8 Animal Weighing Using AUTO-LOC Feature
The M640 will lock on an animals weight and stay locked even after the animal is off
the scale. A new AUTO-LOC weight will only be retriggered upon placing the next
animal on the scale.
1. Turn indicator on use the G/N key to access the gross mode, and press the
ZERO CLEAR key…
Display shows 0
2. Move animal onto the scale…
L WWWW is shown. WWWW = animals auto-locked weight
If a false locked weight occurred, press ZERO/CLEAR to recheck the
animals weight. This will also delete from the accumulators the last
locked-on weight and replace it with the new locked-on weight.
If autoaccumulate is on, once the weight is locked-on, the Model 640 will
automatically accumulate to the last selected memory channel.
Weight stays locked until the next animal is on the scale.
Also to prevent an inadvertent AUTO-LOC if someone leans/steps on
the scale, we recommend putting in a large amount for the MIN.WT
parameter to prevent this from occurring. (EX: 300 lb)
3. Remove the animal…
L WWWW is shown
4. Repeat steps 2 and 3…
After weight starts rising and goes beyond the MIN.WT the scale will
briefly show actual weight before triggering a new auto-locked weight.

8.1 How to Verify the Scale is Weighing Properly
8 Appendix: Quick Programming Guide
In most cases your Avery Weigh-Tronix Model 640 arrives from your dealer or
distributor preprogrammed with a Configuration Code Number (CCN) that sets the
Model 640 to work and weigh properly with the appropriate scale system, whether it is
a TMR mixer, grain cart, livestock scale, weigh cart, platform scale, bin scale, or all
other applications.
Before beginning to use the new Model 640 scale system, please verify the system has
been programmed correctly and is weighing properly and it is configured for the proper
unit of measure.
8.1 How to Verify the Scale is Weighing Properly
1. Zero the indicator by pressing the ZERO/CLEAR key from the gross mode.
2. Stand on the scale system and note the scale reading.
If the weight reading is correct, your system is working properly and
you can continue with operation of the system.
If the weight reading is not correct, read through this Appendix. This
will tell you how to access the SETUP menu to change the Configuration
Code Number (CCN). This should get your system up and running
properly. If you have further problems, call your local dealer or Avery
Weigh-Tronix.

the recommended Configuration Code Numbers and keep entering code numbers until
the scale appears to be weighing properly. (See section below entitled: Entering A New
Configuration Code Number)
After several attempts at a code number, if the scale still does not weigh properly
please consider the following:
l Contact your dealer or distributor where the scale was purchased
l Access the Avery Weigh-Tronix website at www.agscales.com for more
debugging tips
l Contact the Avery Weigh-Tronix service department at 1-800-458-7062 for
assistance
8.1.4 Configuring the Model 640 for Other Brand Weigh Bars and Loadcells
The Model 640 will work with any brand of strain gage based weigh bar or load cell.
Once the system is installed, the Model 640 will then need to be calibrated. This can
be accomplished by placing a known weight on the scale and then calculating the
sensitivity output based on information from the weigh bar or load cell that can be
directly entered into the indicator.
In the case of other brands other than Avery Weigh-Tronix, two configuration code
numbers must be entered into the Model 640:
l Configuration Code Number
l Custom Calibration Number
As discussed previously, the Configuration Code Number for a custom setting can be
derived by referencing Tables 8.1 through 8.3 to determine the Configuration Code
Number and using codes 97XXX through 99XXX, then a CUSTOM CALIBRATION
number will need to be calculated. Enter the Configuration number that comes closest
to how the scale needs to be configured.
Now a Custom Calibration Number needs to be calculated. This can be derived by two
methods; either get the information from the weigh bars that are being use as shown
here:
58 Model 640 Indicator Series User Instructions
8.1 How to Verify the Scale is Weighing Properly
Example 1:
Need to calibrate to 4 weigh bars with the following information:
1 weigh bar 2.0 mV/V = 5,000 lb
Therefore 4 weigh bars would be 2.0 mV/V = 20,000 lb for the system
CUSTOM calibration number needs to be weight value at .4mV/V or 4,000 lb.
OR
The other method is to first enter in the Configuration Code Number (97XXX through
99XXX) and then place a known weight on the scale. Record that weight and then
figure the scale factor difference from the known weight and the displayed weight. Then
this factor needs to be multiplied by the current CUSTOM number to calculate the new
CUSTOM number.
Example 2:
Current CUSTOM configuration Code = 4000
To access CUSTOM number, reference the next section <blue><italic>Viewing/
Entering a Custom Calibration Number
Known Weight Applied 15,000
M640 Displayed Weight 10,000
Known Weight/ Displayed Weight 1.5000
(New CUSTOM #) = (Current CUSTOM #) x (Calibration Factor)
6000 = 4000 x 1.5
Therefore go to the CUSTOM CALIBRATION setting in the SETUP menu and change
as needed.
8.1.5 Viewing/Entering a Custom Calibration Number
EXAMPLE: System capacity of 2 mV/v at 20000 lb, or .4 mv/v=4000 lb
The custom number as stated would be the weight value at 0.4 mv/v or as in this
example 4000 lb.
You cannot access the CUSTOM number until the CCN, starting with 97XXX through
99XXX, has been entered.
1. From the CONFIG display, press HOLD/MENU once…
CUSTOM is shown
2. Press the PRINT/SELECT key…
Current weight is shown. Default value of custom = 20000, or 0.4 mv/v at
20,000 lb.
3. Use the numeric entry procedure to enter 4000…
4000 is shown.
4. Press the PRINT/SELECT key…

8.2 How to Configure Filtering
If you need to adjust the filtering on your Model 640 to counteract excessive movement
or vibration on the scale system, follow these steps to access the FILTER menu item
of the Setup menu and make needed changes.
1. Access the Setup menu from the G/N mode. To do so, press and hold the
HOLD/MENU key for three beeps (3 seconds), then release…
SET.PAS is displayed.
2. Use the numeric entry procedure, see note below, to enter the password 640.
Press PRINT/SELECT to accept it…
640 is shown
3. Press PRINT/SELECT once more…
60 Model 640 Indicator Series User Instructions
CONFIG is displayed.
8.2 How to Configure Filtering
4. Repeatedly press the HOLD/MENU key until…
FILTER is displayed. There are two parts to filtering; Constant and
Window. How to set these is explained below. How they affect weighing
is explained in the Filtering note below.
Filtering:
Default settings; CONST=2, WINDOW=0
If the value for the constant (CONST) = OFF, the filtering is disabled. If a value for
CONST is entered, filtering is ON and you must also enter a WINDOW value. Set the
CONST number small for small vibration problems and higher for more dampening
effect.
The WINDOW threshold parameter defines a weight window that enables the filtering.
The recommended value of 0 is the default, which means the filtering is engaged all
the time.
Example: A WINDOW setting of 10 means a weight change over 10 pounds occurring
during the display update time will disable the filter until the weight change during the
sample time remains within 10 lbs.
5. Press the PRINT/SELECT key twice…
The current CONSTANT value is shown. Press the HOLD/MENU key to
increase the value. Increasing this value causes the indicator to ignore
increasing amounts of weight change on the scale. This means small
changes can be ignored at a relatively small Constant value. To filter
larger changes out, choose a larger Constant value. (Choices are OFF
to 10, Default=2)
6. When the value you want to try is displayed, press the PRINT/SELECT key…
Your choice is selected and CONST is displayed.
7. Press the HOLD/MENU key…
WINDOW is displayed. This is where you will set the threshold window
of the filter parameter. You can enter 0 to full capacity.
8. Press the PRINT/SELECT key…
Current setting for the threshold window is displayed.
9. Use the numeric entry procedure to enter a new value. Press the PRINT/
SELECT key to accept it…
WINDOW is displayed.
10. Repeatedly press the G/N key until you return to the gross weighing mode.
Check the function of the indicator. If the weight display does not act in a manner to
your liking, repeat steps 1 through 9 until the indicator functions as desired.

9.1 Power ON Problems
If after applying power to the indicator it does not power on, check the following items
and then try to power on after each step.
1. Check Input Voltage: Required voltage into the indicator is 10-17 volts
negative ground. If the voltage is between 9-10 volts the indicator will alternate
between LOW.BAT and appropriate mode. The indicator will automatically turn
off if the voltage drops below 9 volts for more than five seconds. Make sure to
check the connections for corrosion, and or bent pins and reconnect the power
source. Also inspect the power cable for possible damage Again the unit can be
powered directly from a 12VDC battery or a 120/240 VAC power transformer.
WARNING: You must disconnect power from indicator before charging or jump
starting a battery.
If using a standard Avery Weigh-Tronix battery power cable, connect the BLACK
wire to Ground and the WHITE wire to +12VDC.
Always disconnect all cables connecting to the indicator before welding on any
OEM equipment. If not damage from high currents may cause internal damage.
2. Internal Fuse: A 3.15 Amp fuse is internal on the PC board, replace with
Avery Weigh-Tronix style fuse or equivalent (AWT P/N 48561-0190). Make
sure the new fuse is the proper size. Using a fuse with too high of a current
rating can cause costly damage to the indicator and will void your warranty.
The fuse is soldered directly to the main board and should be replaced by a
certified scale technician.
62 Model 640 Indicator Series User Instructions
9.2 Indicator +/- RANGE Problem
3 volt coin cell battery
3. Internal 3 volt coin cell battery: The Model 640 has an internal coin cell
battery which provides backup power for retention of the time and date, and
the 100 memory channel accumulator data. During normal operation, when
power is turned off all this information is saved. After 4-5 years the coin cell
battery will be drained. When this happens and the unit is turned off, the
information will be lost and the indicator will no longer turn on. When this
occurs, you must replace the coin cell battery to resume normal indicator
function.
To access the battery, remove the front screws on the 640/XL or the back
screws on a 640M and replace the coin cell battery (B1) on the main electronic
board. See location in Figure 9.1.
Figure 9.1 Coin cell battery location on the main board
Be sure to replace the battery(b1) with the same or equivalent type
recommended by the manufacturer. Avery Weigh-Tronix PN of the battery is
60207-0013.
4. Check All Incoming Cables: Now try pressing the ON/OFF key and see if the
M640 will turn on. If not disconnect all incoming cables and try one last time, if
it still will not turn on there is a definite problem with the M640. Please send it
to a certified service center or return to Avery Weigh-Tronix.
9.2 Indicator +/- RANGE Problem
An over Ranged Indicator is represented by either +/- RANGE on the display, and is
typical until weigh bars or load cells are actually plugged into the unit. Once a weight
sensor is plugged in, actual readings will be displayed and the indicator can be zeroed.
The +/- RANGE represents more than +/- 8 mv/v input.
Model 640 Indicator Series User Instructions 63
9 Appendix: Troubleshooting
9.3 Indicator Over or Under Capacity Problem
This situation occurs when the input from the weigh bars or load sensors exceed the
capacity of the Model 640.
1. If indicator shows either upper or lower dashes on the display, press ZERO/
CLEAR when the scale is empty to establish a zero weight readings.
2. If the unit still does not zero, then it is most likely a problem with a weigh bar.
Plug one weigh bar in at a time and press the ZERO/CLEAR key, and when a
weigh bar is found that will not zero from the under or overcapacity screen
then it is probably a defective weigh bar. Check for cable damage and fix or
replace weigh bar or sensor as needed or repair immediately.
9.4 Inaccurate Weight Readings
1. Please check and reference Appendix X Quick Programming Guide and see if
the Configuration Code Number (CCN)) is properly entered for the scale
application. If not known please consult dealer or distributor of final OEM
product for assistance.
2. If Configuration Code Number (CCN) is entered properly do a visual inspection
of the scale system and check for:
l Cable Damage to Weigh Bar cables or junction box cable
l Make sure the supporting structure and weighing structure do not touch at
any other point except at the weigh bars.
3. Next if the scale is still not weighing properly, check for faulty weigh bars as
follows:
l Position a person or heavy object on the scale system above each weigh bar,
one weigh bar at a time, and compare the weight readings.
l All the readings should be nearly identical to each other. One reading that is
significantly different from the others is probably defective. Replace as
necessary.
9.5 Drifting Weight Readings
1. If weight readings drift, disconnect weigh bars and plug one bar in at a time until
the bar that is plugged in makes the readings drift around considerably. The last
weigh bar plugged in that makes this happen is probably the defective weigh
bar. Again if all bars are unplugged the indicator will show +/- RANGE.
2. If weigh bars are plugged into a J-box and none of the weigh bars will stabilize
the indicator then either the indicator is faulty or the junction box interface
cable is faulty.
