| Conveyor Gear Motor | If DC voltage is present A+ and A- and the motor does |
|
| not run, first check the mini breaker and then the |
|
| conveyor. Refer to the next possible cause. Check |
|
| motor brushes for excessive or abnormal wear, |
|
| replace as needed. Check the leads to the motor for |
|
| evidence of any shorts or opens, and each lead to |
|
| ground. If the motor fails the above tests, replace |
|
| motor. |
| Conveyor | Check for any mechanical |
|
| adjustment. Also check for worn bearings. The |
|
| Installation and Operations Manual shows proper |

|
| tightened will cause excessive bearing wear and |
|
| sometimes, irregular speed. |
Conveyor speed | Power Supply | Check power supply at the DC control board for the |
varying |
| 120 VAC at board terminals L1 and L2. If voltage is |
|
| not present, check main circuit breakers |
| DC Gearmotor | If the DC control board is steady, then the problem |
|
| may be the motor or gearbox: Check the brushes in |
|
| the motor for excessive arching and/or unusual wear. |
|
| Check the motor and gearbox from instruction located |
|
| on page 20 under "possible cause" listing "Conveyor |
|
| gear motor". |
| Magnet | Check to insure that the magnet cemented to shaft of |
|
| conveyor drive motor) has not been damaged, or |
|
| come loose from motor shaft. Replace as needed. |
| Hall Effect Sensor | Check for any physical damage to Hall Effect Sensor |
|
| (mounted on conveyor stepper drive motor. Check all |
|
| wiring and connections for damage. Check all |
|
