Cleveland Motion Controls Classic CLT Cantilevered Transducer REV AA - Manual (Page 11)

AO-70135 11 of 11
5.2 OUTPUT SIGNAL FAILS TO INCREASE
WITH ADDED LOAD
The transducer is overloaded and is hitting the
mechanical stop. Replace the transducer with one
having a higher maximum working force or reduce the
load. (This may be accomplished by reducing the web
wrap angle.)
5.3 WRONG POLARITY OF OUTPUT
SIGNAL
Transducer may have been incorrectly oriented. Make
certain that the web force is being applied to the top side
of the transducer which is identified by the load line label
as shown in Figure 2 on page 3. If rotation is impossible,
interchange the transducer leads as instructed in the
tension indicator or controller manual.
5.4 NO OUTPUT SIGNAL
Check to see that all connections have been made
completely. Check for places where the connecting
cable might be crimped or cut.
5.5 VERY HIGH OUTPUT WITH NO LOAD
Check cable and connector for good connections and
check continuity of cable with an ohmmeter. Check for
proper wiring to transducer. Check transducer gage
resistance as given in the following chart at room
temperature with no load applied.
