Standard troubleshooting procedures
Procedure 1 (P1) - Initialise the control box (reset)
This procedure resets all columns to the fully retracted position so that the control box knows where
they are.
Note: This is commonly the solution when a complaint is that a desk will move down but not up.
When a control box requires initialisation, this is how the system is programmed to behave.
1. Hold DOWN button on desk panel to ensure the columns are retracted to their lower limit
(whether it is the fully retracted hard stop or a configured lower limit).
2. Briefly release DOWN.
3. Press and hold DOWN for 5 seconds, wait until all desk movement has stopped, then release.
3.1. If initialisation is successful, columns will do a slight up/down “handshake” movement.
3.2. If you have a desk panel with display, E01 is displayed during this part of the procedure.
Procedure 2 (P2) - Check all cable connections
1. Mains cable, connected to both the control box and power outlet.
2. All motor cables, connected to both the control box and column.
2.1. Assuming a standard control box configuration, these must be connected in channels
1 and 2, or channels 1, 2 and 3 for a 3-legged table. They cannot be connected
in channels 1 and 3 or 2 and 3 unless there is a configuration on the control box
specifying this arrangement.
3. Desk panel cable, connected to the control box in either port A1 or port A2.
Procedure 3 (P3) - Check for obstructions
1. Check under, above and on the sides of the desk for any obstructions that could prevent
movement in either direction.
Procedures 4 and 5 are for a two-legged desk system. The same concepts can be used for a three-
legged system using Channel 3 and so forth.
Procedure 4 (P4) - Check for faulty component(s) WITH error codes
(digital display on desk panel, or on app via Bluetooth
®
)
Notes: Check the Error codes list for assistance. The code should read E##. Some error codes are
channel-specific which can help pinpoint the problem.
Symptom Remedy
System will move down but
not up.
1. Initialise (see Procedure 1 (P1)).
System unresponsive
(no power to display when
any button is pressed). If any
of these steps activates the
digital display, initialise the
system (see Procedure 1 (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.
