LINAK DESKLINE Troubleshooting
Glossary of Common Terms
• Components
» Desk leg (DL) – The lifting columns, typically with powder coated steel profiles, responsible for lifting the working load of
the application.
» Control box (CBD6S) – Both the computer and power supply of the system.
» Desk panel (DP) – The user interface. Depending on the model, it is used to activate the application, set memory
positions, display the height, display error codes, connect to mobile apps, and give reminders to the user.
» Motor cable – Transmits low voltage power (18-39 VDC) from the control box to the desk legs, and also transmits PIEZO
signals when available from the desk leg.
» Mains cable – Transmits high voltage power (120 VAC in US and Canada) to the control box.
• Other
» Initialize – Procedure to reset all desk legs to the fully retracted position so that the control box knows where they are.
» Reference – Any group of desk legs that run in parallel when an Up or Down command is sent to the control box. It is
possible to have a custom control box configuration that allows for more than one Reference. [Example: Two (2) desk
legs on Reference #1 (Channels #1 and #2) to lift a work surface, and one (1) LA31 on Reference #2 (Channel 3) to adjust
a monitor array.]
Standard Troubleshooting Procedures
P1 – Initialize the control box (“reset”)
Note: This is commonly the solution when a complaint is that a desk will move down but not up. When a control box requires
initialization, this is how the system is programmed to behave.
STEP 1. Hold Down button on desk panel to ensure the desk is retracted to its lower limit (whether it’s the fully retracted hard
stop, or a configured lower limit).
STEP 2. Briefly release Down
STEP 3. Press and hold Down for 5 seconds, wait until all desk movement has stopped, then release
a. If initialization is successful, you should see a slight up/down “handshake” movement of the desk legs
b. If you have a desk panel with display, you should also see E01 during this part of the procedure.
P2 – Check all cable connections
STEP 1. Mains cable, connected to both the control box and power outlet.
STEP 2. All motor cables, connected to both the control box and desk leg.
a. Assuming a standard control box configuration, these must be connected in channels 1 and 2, or channels 1, 2 and
3 for a 3-leg table. They can’t be connected in channels 1 and 3 or 2 and 3 unless there is a configuration on the
control box specifying this arrangement.
STEP 3. Desk panel cable, connected to the control box in either port A1 or A2 (doesn’t matter which)

Symptom Procedure
System will move down but not up 1. Initialize (P1)
System unresponsive (no power to
display with any button is pressed).
If any of these steps activates the
digital display, initialize the system
(P1).
1. Check mains cable connection
2. Test power outlet using another device (lamp, phone charger, etc.)
3. Plug in a new switch and test
4. Connect all existing cables to a new control box and test
System is powered, but will not
initialize
1. Try pressing and releasing the down button a few times before pressing and holding
for 5 seconds.
2. Also, be aware if the control box has a special configuration: If the desk is
programmed with a lower stroke limit, so as to avoid a collision with something like
a file cabinet, it is possible that it also has a custom, longer Forced Initialization
Time. This is the time required to hold Down before initialization begins. Sometimes
this is 10 seconds or longer.
3. If you have a standard control box without a special configuration (i.e. “Plug &
Play”), try to initialize each leg in Channel 1 by itself, with nothing else plugged into
the motor channels on the control box. Also, swap the motor cables so that a
different motor cable is used to initialize Channel 1 by itself. The problem could be a
faulty desk leg or a faulty motor cable.
Channel-specific error (Ex: E41 –
Channel 1 overload) – Everything
except PIEZO errors (E59-E63)
1. Swap the motor cable connections at the control box (Motor cable #1 from channel
1 to 2, motor cable #2 from channel 2 to 1). If It remains E41, there could be a
problem with the application (load or obstruction on one side) or a bad control box.
If the error changes to E42, go to step 2.
2. Swap the motor cable connections at the desk legs, so that the leg that was
originally connected to Channel 1 is back in Channel 1, but with the motor cable
that was originally connected to Channel 2. If it remains E42, it is most likely a bad
motor cable, now connected to Channel 2. If it goes back to E41, it is most likely a
bad desk leg, now connected to Channel 1.
P3 – Check for obstructions
STEP 1. Check under, above and on the sides of the desk for any obstructions that could prevent movement in either direction.
The next two procedures (P4 and P5) are for a two leg desk system. The same concepts can be used for a three leg system using
Channel 3 and so forth.
P4 – Check for faulty component(s) WITH error codes (digital display on Desk Panel, or on app via Bluetooth)
Notes: Check the error code list in the appendix of this troubleshooting guide for assistance. The code should read E##. Some
error codes are channel-specific which can help pinpoint the problem.
