PROBLEMS & TROUBLESHOOTING

Weighing issues

•
Make sure setup and calibration numbers are correct for all scale platforms.
•
If using a UT, use DAN 1997. This will give system statistics like voltages & estimated load cell quantity.
•
On EZMate systems, make sure all connectors are fully inserted and tightened.
•
On terminal block systems, make sure wire colors are correct and connections are tight.
•
Verify no water in connections, SL2 box, or J-boxes. System is not rated for pressure washing.
•
Check for bad load cell or damaged load cell cable. This can be isolated by scale platform (multi-scale
systems), then by individual bars. Disconnect all but one bar, verify if it weighs correctly, then move on to
the next bar. Once the bad bar is found, repair cable or replace bar as needed.

UT/ ISOBUS System

•
No SL2 mask on UT
o Is ISO function turned on in UT? If SL2 is new, may take a few minutes to load.
o Is ISO plug securely connected to back of tractor?
o Make sure all SL2 and cable connections are secure.
o Make sure terminator is installed near SL2/ end of bus cabling.
o If software was just updated, new UT installed, or new UT/ SL2 combination, make sure you give
several minutes for the SL2 to load its mask up to the UT.
o If software was just updated, make sure your original settings were loaded on the SL2.
o Make sure there is at least 11 volts on the system. Data will not broadcast on CAN or RS232 below
11 volts system power to prevent data corruption.
o The SL2 address conflicts with another ISOBUS device address on your line. Change 'Preferred
Address' on System Setup screen to a different value.
•
SL2 mask on incorrect tractor terminal
o Set preferred UT number. DAN 2705 or 'Preferred UT Number' on System Setup screen of SL2 ISO
mask. Default is 1, so try number 2 to load on other ISO monitor in cab.
o Your monitor has too much bus traffic, or your ISO/ UT screen has reached its maximum device load.
Clearing the object pool cache of the UT may resolve this.
o The SL2 address conflicts with another ISOBUS device address on your line. Change 'Preferred
Address' on System Setup screen to a different value.
•
Weight screens overlap, or screen seems mixed up on SL2 mask
o Change your screen configuration to change what information is displayed. Only display what is
needed, especially on small UT screens. On UT, touch spinning arrow button 2x. This brings up the
System Setup screen. Touch the scale symbol, which will bring up a screen of 8 configuration boxes
for the 4 possible scales. Many screen configuration options are available here to fit most user needs
and most UT screens.
o If you have changed screen layout settings and something still is offset a little, cycle power and allow
SL2 mask to reload. Clearing the UT object pool cache may also help.
