Troubleshooting Guide
| NO. | SYMPTOM | POSSIBLE CAUSE | REMEDY |
| 1 | Power pilot does not lit | 1. Power fuse is burnt. 2. LED burnt. 3. Power switch is burnt. 4. No power input. |
1. Replace a new fuse. 2. Replace LED. 3. Replace switch. 4. Check the switch or replace. |
| 2 | Speed Adjustment no Motion. | 1. Damaged potentiometer. 2. Motor control PCB no output. |
1. Check if potentiometer is 10KΩ, otherwise replace. 2. Replace a new motor control PCB. |
| 3 | Foot switch no motion | Foot switch is damaged. | Check the foot switch or replace. |
| 4 | Forward/Reverse no output | Forward/Reverse switch is damaged. | Check the switch or replace. |
| 5 | Motor no motion | 1. Motor has power input but no motion. 2. Motor control PCB has no power input. 3. Motor control PCB is damaged. |
1. Replace a new motor. 2. Check the transformer or replace. 3. Replace control PCB. |
Illustration of the Control PCB Adjustment
Instructions for adjusting the control PCB:
- Attention when choosing the switches of input and output voltage (115V/230V), disconnect the power timely when doing the switch.
- ACCEL is time accelerating adjustable potentiometer. When the output voltage is 0-90VDC, from 0.5 seconds to 11 seconds can be adjustable; When the output voltage is 0-180VDC, from 0.5 seconds to 22 seconds can be adjustable.
- DECEL is decelerating adjustable potentiometer. When the output voltage is 0-90 VDC, the longest time is 13 seconds; When the output voltage is 0-180VDC, the longest time is 25 seconds.
- MAX SPD is maximal speed adjustable potentiometer; Twist it to the end clockwise to set the maximum speed.
- MIN SPD is minimum speed adjustable potentiometer; Twist it to the end clockwise to set the zero speed anticlockwise.
- INHIBIT is external enable control side. When this function works, the speed of motor is set by MIN SPD.
- TORQUE, IRCOMP are torque and laden adjustable potentiometer.
