Troubleshooting

The control box keeps track of the height of each lifting column so the desk stays level. If the power is cut during movement or a plug comes loose, this information can get mixed up. The desk is not broken, but it needs a reset.

A reset will likely help if

• the desk only moves down
• the desk stops in the middle of a movement
• the display shows RST or a flashing code
• the desk is tilted to one side.

f the reset does not help, the cause is likely in the hardware. It may be a loose motor cable, a faulty control box or handset, or a fault in a lifting column.

1. Check that the power cord and all cables are firmly connected.
2. Try the reset again.
3. If the problem continues, tell us about the issue and your handset model, if you know it.  Contact us → 

Tip: Avoid cutting the power during movement, keep cables secured and spread the weight evenly on the desk.

Possible cause: Power supply, a loose cable or a control box fault.

Try this:

1. Check that the socket has power and that the power cord is firmly connected to both the socket and the control box.
2. Check the handset and motor cables.
3. Unplug the power cord for at least 30 seconds and plug it back in.
4. Reset the desk (see Reset instructions above).
5. If the desk has been adjusted continuously for more than 2 minutes, the overheating protection may stop it. Let the desk rest for about 18 minutes and try again.

If the desk still does not move: Contact us→ 

Possible cause: The control box has lost track of the desk height, often after a power cut or a loose plug.

Try this:

1. Reset the desk (see Reset instructions above).
2. Check that there is not too much weight on the desk and that nothing is blocking the movement.

If the problem continues:  Contact us → 

Find the meaning of the code and the solution under Display messages and error codes below. If the code is not listed, tell us the code and your handset model.

Possible cause: Memory positions may be cleared after a reset or a power cut, or the position was not saved correctly.

Try this:

1. Move the desk to the height you want..
2. Save the height to a memory position again. The saving method depends on the handset, so check it in the user manual.

Possible cause: The lifting columns are out of sync, the load is unevenly distributed or the floor is uneven.

Try this:

1. Reset the desk (see Reset instructions above).
2. Spread the weight evenly on the desk.
3. Check the levelling feet and that the frame screws are tight.

If the desk is still tilted:  Contact us → 

Possible cause: The anti-collision system has detected an obstacle or too much resistance.

Try this:

1. Remove anything under or next to the desk that may block the movement, including cables and chair armrests.
2. Check that there is not too much weight on the desk.
3. Check that the control box is firmly attached under the desk. If it is, the anti-collision may be too sensitive. Sensitivity adjustment: see Display messages and error codes.

If the problem continues: Contact us → 

Possible cause: The handset cable is loose, there is no power or the handset is faulty.

Try this:

1. Check that the handset cable is firmly connected to the control box.
2. Check the power cord and the socket.
3. Unplug the power cord for at least 30 seconds and plug it back in.

If the display stays blank: Contact us → 

The desk is in reset mode. Reset the desk (see Reset instructions above).

Hold the M button for about 8 seconds until numbers appear on the display. The handset is now unlocked.

Unlocking may vary by handset model. For example, on the Perus2 desk handset, the lock is released with a button on the underside of the handset. Watch the video on the Perus2 handset child lock →

The desk has been adjusted continuously for too long (more than 2 minutes), or the control box has heated up, for example in a warm room. Let the desk rest for about 18 minutes, and it will recover on its own.

A control box port (E01 = M1, E02 = M2 and so on) has triggered the overcurrent protection, and the desk does not move. This can be caused by overload when raising the desk, a lifting column that keeps trying to move after reaching its top or bottom position, or a mechanical or electrical fault.

1. Check that there is not too much weight on the desk and that nothing is blocking the movement.
2. Reset the desk.

Important: If the desk tilts during the reset, release the button immediately. Contact us→ 

Applies to desks with two connected control boxes.

1. Check the cable between the control boxes.
2. Unplug the power cord for at least 30 seconds, plug it back in and reset the desk.

If the code does not disappear, one of the control boxes may be faulty:  Contact us → 

The handset is likely faulty and needs to be replaced.  Contact us → 

A height limit has been set for the desk.

1. Press the M button. Release the button for a couple of seconds.
2. Hold the M button again until the display shows 555.

The limit has now been removed.

1. Follow steps 1–2 of the reset (see Reset instructions above) until the display shows RST.
2. Hold the M button for 5 seconds until the height reading flashes.
3. Set the correct reading with the up and down buttons.

When you release the button, the display returns to RST mode after 5 seconds and the setting is saved. Then complete step 3 of the reset.

1. Follow steps 1–2 of the reset (see Reset instructions above) until the display shows RST.
2. Hold memory button 2 for 5 seconds.
3. Select 10.3 (centimetres) or 10.4 (inches) with the up and down buttons.
4. Then complete step 3 of the reset.

1. Follow steps 1–2 of the reset (see Reset instructions above) until the display shows RST.
2. Hold the up button for 5 seconds.
3. Select 10.5 (very sensitive), 10.6 (medium) or 10.7 (less sensitive) with the up and down buttons.
4. Then complete step 3 of the reset.
