GLOSSARY OF COMMON TERMS
Components:
• Desk Leg (DL) - The lifting columns with power coated steel profiles, responsible for lifting the desk.
• Control Box (CBD6S) - Both the computer and power supply of the system
• Handset - 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 desk sensor signals when
available from the desk leg.
• Mains Cable - Transmits high voltage power (120 VAC in US and Canada) to the control box
Other:
• Intialize - 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 handset 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 handset with display, you should also see E01 during this part of the procedure.
P2 - Reset the handset
STEP 1.Press and hold the “bell” button and the “star” button for eight seconds until the LED flashes red.

P3 - 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. Handset cable, connected to the control box in either port A1 or A2 (doesn’t matter which)
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 handset, 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.
Symptom Procedure
System will move down but not up 1. Initialize (P1)
System unresponsive (no power to 1. Check mains cable connection
display with any button is pressed). 2. Test power outlet using another device (lamp, phone charger, etc.)
If any of these steps activates the 3. Plug in a new switch and test
digital display, initialize the system 4. Connect all existing cables to a new control box and test
(P1).
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 – 1. Swap the motor cable connections at the control box (Motor cable #1 from channel 1 to 2, motor cable #2
Channel 1 overload) – Everything from channel 2 to 1). If It remains E41, there could be a problem with the application (load or obstruction on
except desk sensor errors (E59-E63) 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.

Symptom Procedure
Desk is uneven 1. Initialize the desk. If both legs begin to run down, complete the initialization. If only one leg moves, stop and
move to Step 2.
2. Check motor cable connections. Check to ensure motor cables are not pulled during movement. With a
standard, Plug & Play control box, it’s possible that only one leg is connected, and connected to Channel 1. In
this case, it will initialize and run Channel 1 only. If there is only one leg but it’s connected to Channel 2, it will
not initialize.
3. If a motor cable was disconnected, try initializing again.
4. If unsuccessful, connect the desk leg from Channel 2 into Channel 1, with nothing in Channel 2, and initialize.
5. Try initializing the same leg that’s in Channel 1, but with a different motor cable. If it still won’t initialize,
replace the desk leg.
P5 - Check for faulty component WITHOUT error codes (no digital display on handset, no Bluetooth)
Symptom Procedure
System will move down but not up 1. Initialize (P1)
System will not initialize.
OR
System won’t complete the full range of
motion.
– After each of these steps, attempt
to initialize (P1).
1. Check mains cable connection. Test power outlet using another device (lamp, phone charger, etc.)
2. Plug in a new switch.
3. Connect all existing cables to a new control box.
4. Try pressing and releasing the down button a few times before pressing and holding for 5 seconds.
5. 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.
6. 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.
Desk is uneven 1. Desk is uneven (P4)

APPENDIX
What is the Control Box Thinking?
There are many clever procedures, checks and measurements performed in the control box. Here is a brief description of what the control box is trying to
accomplish while it is activating an application:
• Safe activation of the application
- Parallel, even movement of all desk legs in the application is critical.
» The control box does not directly know the position of each desk leg. Instead, the position of each leg is constantly calculated via Hall pulses from
each motor. The legs on a single reference are not allowed to be more than +/- 5 Hall pulses out of sync. For a standard DL, this amounts to +/-
0.55 mm.
» Motor cable disconnections are also detected as errors.
- If desk sensor technology is present in the desk leg, the control box monitors for desk sensor “collision” signals from each channel. When a desk sensor
signal is sensed, movement is immediately stopped and, if there is room, the system is ran in the opposite direction a small distance.
- Anytime the control sees an incomplete signal, or more than one signal (multiple keys pressed, multiple handsets activated at the same time), an error
is determined and no movement is allowed at that moment. This is to prevent an action of movement that is not intended by the user.
• Protection from equipment damage
- Internal temperature of the control box is monitored.
- Maximum current draw for each motor channel, as well as the system as a whole, is measured. When the current exceeds an allowable limit, an error
is presented.
