General Symptom List
Solution
1. Make sure the labels are
loaded correctly (page 41).
2. Verify that the dancer
spring is attached. Replace
the dancer spring if worn.
3. The LED should be on
when the dancer roller is in
the up position. If not, check
the connections and the
24vdc power supply or
replace the proximity
switch.
4. If not, check the wiring
connections or replace the
24vdc relay.
5. Replace broken or worn
parts.
6. When the proximity LED is
on the relay contact should
close and the motor will turn
on. If not, measure the
voltage across the motor
leads. This should read
18.5 to 19 VDC or 82 to 84
rpm. Adjust the main pot on
the motor control board.
