assembly. Check for damaged or torn belting. Check
conveyor shaft bearings for damage or excessive wear.
Repair or replace conveyor components as needed.
Conveyor speed varying or
intermittent
Power supply Check for a steady 120VAC supply to the conveyor
control. If voltage is not steady, trace back to power
supply.
Control, conveyor Check for a steady DC voltage output at terminals A+
and A-. If voltage is not steady, proceed. Check for
5 VDC output from the conveyor control at terminals
+5V(red) and COM (black). If there is no voltage output,
replace the conveyor control. If there is DC output,
proceed.
Motor, conveyor Check conveyor motor and gearbox for any visible
damage. If there is apparent damage, repair or replace
conveyor motor. Check motor brushes for excessive or
abnormal wear. Replace motor brushes as needed.
Hall effect sensor/magnet Check to be sure that the Hall effect sensor and
magnet are mounted on the motor. Check for any
visible damage to the Hall effect sensor and magnet. If
there is visible damage, repair or replace as needed. If
there is no visible damage, check for a frequency
output from the hall effect sensor at terminals SIG
(white) and COM (black).
Readings should be as follows:
2:15 cook time 56 Hz. approx.
5:00 25 Hz. approx.
10:00 13 Hz. approx.
16:00 8 Hz. approx.
If these readings are not achieved, replace the Hall
effect sensor/magnet
