POTENTIAL SOLUTION
Check outlet with another device;
check circuit breakers/fuses/wiring.
Confi rm proper cable engagement into wall outlet.
Check that Power Cable is fully seated into Control Box.
(see Fig. 1 on page 6)
Inspect the Power Cable for damage; replace any damaged cables.
Check that all cables are connected per the Assembly Directions.
When fi rst plugged in, the Control Box will click twice to confi rm
proper connection.
See above.
Control Box fi rmware must be 1.9 or later for Digital/Preset Controller
compatibility. (see Fig. 4 on page 6)
See above.
Maximum load capacity is 103 kg. Overloading the Desk
could lead to damage that would not be covered by warranty.
ERROR CODE E24/25/26, E48/49 = Over Current
Tip: When calculating lifting capacity, subtract the weight
of the worksurface
Perform initialization procedure. (see Common Procedures)
Lower Desk all the way down, and perform synchronization
procedure. (see Common Procedures)
Ensure the Desk is in 'Standby' mode. (>20 seconds of inactivity)
Unplug each multi-pin connection point and inspect the pins in the
Control Box connector.
Are they all straight, and making good contact?
If not, try using a push-pin to straighten them. (see Fig. 2 on page 6)
(Otherwise, replace necessary components with undamaged versions.)
Carefully check the condition of the Low-Voltage Cable of each
Lifting Column. (see Fig. 3 on page 6)
If any Low-Voltage Cables are damaged, the entire Lifting Column
must be replaced.
To prevent further damage, the Control Box will the whole Desk
down if one Lifting Column is faulty. Test Lifting Columns (see step 4
of Troubleshooting Steps), and replace any faulty Lifting Columns.
Swap with Controller known to work (and/or) check operation.
Control Box fi rmware before version 1.9 is not compatible with the
Digital/Preset Controller. (see Fig. 4 on page 6)
Replace with a new Control Box with fi rmware 1.9 or later.
Swap with Control Box known to work.
Unplug Power Cable from wall. Unplug each multi-pin connection
point, and inspect the pins. Are they all straight, and making good
contact? If not, try using a push-pin to straighten them.
(See Fig. 2 on page 6) (Otherwise, replace necessary components
with undamaged versions.)
