The Encoder is a Rotary Sensor which provides the Programmable Logic Controller
(PLC) with a "0" to "359"
degree value. The unit operates on 5 VDC plus or minus 0.2 VDC and is connected with a 50 foot cable between
the Encoder and input module 115. The word value may be monitored by using the "ENCODER" screen or the
"DATA TABLE ACCESS" screen.
- Monitor the Encoder word value 115 using the "DATA TABLE ACCESS" screen.
- Rotate the Encoder by hand in the same direction the machine rotates. The Encoder coupler must be
loose to perform this function.
- Insure the Encoder provides a "0" to "359" degree value and increments by ones.
- The coupler needs to be tightened after this procedure. The value must be equal to 100 at 1st stop.
- If letters appeared during the check, any one bit stays on, or the numbers do not increment by ones,
check the following:
a) Check for 5 VDC plus or minus 0.2 VDC at the Encoder connector pins Z and X. Wire 160 & 161.
The VDC power supply in the electrical panel may need to be adjusted.
b) Insure the cable connections at the input module 115 are secure and dust free.
c) Insure the Encoder is secure and clean. Use of contact cleaner on the connectors may be necessary.
d) Insure the Encoder cover is secure. If not, inspect the internal components for any contamination.
Clean if necessary and replace cover.
Vibration of the Encoder will cause premature failure. Besser recommends the use of an Anti-Vibration Kit
to protect against this problem.
