TARGET BIN SCALE RF
Problem
Cause
Solution
The weight reading
never changes
The wiring is incorrect
Check the wiring and make sure the input
voltage of the load bar is not 0V.
There is a short-circuit at the load
bar input.
Replace the defective unit.
Load bars are af-
fected by thunder-
storms.
The grounding of bin legs is incor-
rect.
Make sure ground straps are connected as
shown on the mounting instructions of the
load bars.
The accuracy of
the weight reading
changes as the bin
discharges itself.
Bad calibration.
Recalibrate the bin.
The washer between the load bar
and the bin leg is not installed or not
mounted correctly.
Empty the bin then install the washer.
Once the washer is properly installed,
recalibrate the bin.
The bin weight is not distributed
evenly on the bin legs.
Make sure the feed weight is distributed
evenly in the bin.
The LCT light
does not flash
The voltage between PWR and
GND terminals of the LCT module
or between terminals 1 and 4 of
the main controller is too low.
(5-11VDC)
The voltage selection switch
is in the wrong position. Set the switch to
the correct position.
There is no voltage between PWR
and GND terminals of the LCT
module or between terminals 1
and 4 of the main controller.
Fuse F2 of the main controller is blown.
Turn the power off and replace the fuse. If
the fuse blows regularly, check the wiring
or replace the LCT module.
ID numbers are not
set properly.
Make sure the ID numbers are set as fol-
lows:
ID # 1 = LCT-3 module of bin 1
ID # 2 = LCT-3 module of bin 2
ID # 3 = LCT-3 module of bin 3
ID # 4 = LCT-3 module of bin 4.
The end of line jumpers
are not positioned correctly.
Set the end of line jumpers to YES at both
ends of the communication line. The other
end of line jumpers must be set to NO.
The wiring between
the LCT module and the main
controller is incorrect.
Fix the wiring.
The LCT module is defective.
Replace the defective module.

IMPORTANT: When the calibration is
over, write down the calibration Offset
value on the worksheet at the end of
this manual.
Stability Tolerance —
The controller can only
calibrate a bin when the weight reading is
stable enough. Otherwise, it will display an
error message. The stability tolerance is the
variation in the weight reading the controller
can tolerate to calibrate the bin scale. By
default it is set to 2000. *
The weight reading
may be unstable in windy conditions. We thus suggest
to wait for a mild day to perform the calibration.
If this is not possible, increase the stability value
in steps of 1000 each time the controller gives an
error message.
Calibrate? —
Select "Yes" to calibrate the
bin scale. The message "Please Wait" is
displayed. Wait until the end of the calibra-
tion (this process may take a few minutes).
At the end of the calibration, the controller
defines an offset value. Write this value down
on the worksheet at the end of this manual.
This value will allow you to recover your
calibration settings after making controller
updates.
If calibration is successful, the message "Please
Wait" disappears and the "- - - - " display
switches back to "No"; if it fails, the controller
displays "ERROR". In case of an error, increase
the stability tolerance value by 1000 then try
calibrating the scale once again.
IMPORTANT: Write down the calibration
Offset value on the worksheet at the
end of this manual.
Recovering your Calibration Settings
After a new configuration is loaded in the con-
troller, the controller looses all of its calibration
settings. If you know the value of your previous
calibration offset, you can recover your calibra-
tion settings as explained below.
1. From the main menu, select:
» 7. Installation*
» 2. Calibration.
» x. Select the desired bin
» 1. Bin #x One Point
*This menu is only accessible from the installer
mode (see sec. 5.2).

2. Set the following parameters (refer to the
beginning of this section to get information
about these parameters):
Sen.LC#x —
Sensitivity of the load cells.
Max Cap. —
Max capacity of the load cells.
Tare —
Estimate the amount of feed in the bin.
Calibrate? —
Select "Yes" to calibrate the
bin scale. The controller will define a new
offset value.
3. Replace the newly calculated offset by
the offset value coming from your previous
calibration. This way, you will recover your
previous calibration settings.
