TROUBLESHOOTING

Q1: When moving upwards, the desk stops moving then drops 1 cm.

A1: Ensure that the total load on the desk (including the weight of the desktop itself) does not exceed 176 lbs. (80 kg). Remove the excess weight and ensure that there are no obstructions to upward movement. Perform a System Reset.

Q2: When moving downwards, the desk stops moving then raises 1 cm.

A2: Ensure that there are no obstacles to prevent the desk from freely moving downwards. Perform a System Reset.

When an error occurs, the Display will show one of the following codes:

ER1: The downward movement has caused the desktop to reach the minimum height before it thinks it should or the overcurrent protection circuit has been triggered three times. Remove any obstacles and perform a System Reset to clear the error.

ER2: The system has overheated and needs time to cool down. The error code will clear automatically when operation can be resumed.

ER3: There is a motor cable connection problem. Check that all electrical connections are secure.

ER4: The two legs are at different heights. Perform a System Reset to clear the error.

ER5: The motor has a fault.

HOT: The system has been operated continuously for more than 2 minutes and has overheated. The system will return to normal operation after 18 minutes have elapsed. Do not unplug the desk during the cool down time.
