5-6 Troubleshooting
Front Load and Setpoints LED Displays Are Blank (4-Channel Units)
If no values appear in the Front Load and Setpoints LED displays on a 4-channel AutoSet, do
the following:
•
Check the setting of Mode switch #7 (see page 4-14). If the switch is set to ON, which
enables 2-channel operation in a 4-channel AutoSet, change the setting back to OFF, the
default.
•
If setting switch #7 to OFF does not solve the problem, or if the switch is already in the
OFF position, contact Wintriss Tech. Support.
Load LED Display(s) Shows Zero Tonnage
If one or more Load LED displays consistently read “0” tons, do the following:
•
Check to make sure that the latching magnetic cam switch (LMCS) used for the zero cam
function has been connected properly. Make sure that the LMCS is closed to ground during
the top of the stroke and open at the bottom of the stroke. Also, check to make sure that the
red and blue magnets are positioned at the correct angles on the crankshaft. See
Installing
the Latching Magnetic Cam Switch (LMCS) , page 2-17.
•
Check to make sure that the mounting and wiring of the corresponding strain link(s) were
performed correctly. Verify that the strain links are mounted on a flat, clean surface and are
wired correctly. See
Installing Strain Links , page 2-10.
Tonnage Shown in Load LED Displays Is Too Low
If the tonnage shown in one or more Load LED displays is lower than you think it should be,
do the following:
