WARNING
These Troubleshooting Instructions are for use
by qualified personnel only. To reduce the risk
of electric shock, do not perform any servicing
other than that contained in the Operating
Instructions unless you are qualified to do so.
4.0 TROUBLESHOOTING
4.1 EXCESSIVE OUTPUT SIGNAL
WITH NO LOAD
Try to re-zero with zeroing pot(s).
There may be a high degree of misalignment of the
transducers causing a severe pre-load.
or
The sensing guide roll assembly may be excessively
heavy. The sensing guide roll should not weigh more
than ½ the maximum working force of the transducers
in most cases.
4.2 LOW OUTPUT SIGNAL
The transducer may have too large a maximum working
force for the application. Replace with a lower
maximum working force transducer or increase web
wrap angle.
4.3 OUTPUT SIGNAL FAILS TO INCREASE
WITH ADDED LOAD
The transducers are overloaded and are hitting their
stops. Replace the transducers with ones having a
higher maximum working force or reduce the load. This
may be accomplished by reducing the web wrap angle
and/or using a lighter sensing roll.
4.4 WRONG POLARITY OF OUTPUT
SIGNAL
Transducers may have been incorrectly oriented. Rotate
transducers 180 degrees or if rotation is impossible,
interchange the red and the black transducer cable leads
at the tension indicator.
