Transmission protection / assembly error

| 1. One of the table legs was mounted upside down. Place the table upside down on the floor and swap the table leg. If the table legs are at the same height, the assembly is correct. Also check that both table legs are connected to the center rail / connecting axis.

2. Motor transmission error / not enough voltage. Disconnect the power cable from the power supply. Wait for 20 minutes. Try again.

E31| Under voltage protection / under- supply| Disconnect the power cable from the power supply. Check that the cables are connected to the controller (compare “Process 14” in the assembly instructions). Reconnect the power cable to the power supply and try again.

Once you can see the hole, you must turn the center rail / connecting axis the other way around. Then connect manually. Once both legs are the same height at the lowest height setting, reconnect to the center rail / connecting axis.
The center rail / connecting axis cannot be adjusted.| Look at the construction again. In the middle of the table there is a small aluminum plate with holes provided for screws with hexagonal profile (see detail number 12, 13).
