Control boxes are not interchangeable. Control boxes are programmed with parameter files for specific height adjustable legs. Unauthorized use of a control box may result in catastrophic damage to the height adjustable legs.

Control boxes make a series of clicking sounds (click codes) when connected to an electrical outlet.
– One click means no parameter file; control box is inoperable.

A programmable hand switch will display a series of dashed lines when connected to an unprogrammed control box.
The hand switch may also display a series of 2’s to indicate a circuit board failure due to an electrical surge.

1 click means the system is in emergency operations mode; it will not function
2 clicks is a normal start up; system is working normally
3 clicks is a power fail error (communication lost)
4 clicks is a system reset
5 clicks is a normal task life reset
6 clicks is a restart due to an unknown root cause
Contact customer service if your system does not function

When a hand switch displays zero(s), it usually means the table assembly was connected to an electrical outlet for the first time. The zero(s) will be displayed on the hand switch for a short period of time before giving way to displaying E61.
Carry out the initialization (reset) procedure when the hand switch displays these codes.

Interrupted signal in the circuit board linked to motor cord port M1, M2 or M3. A problem with the motor cord or motor cord connection was detected (short circuit).
See Troubleshooting Guide

Over current condition linked to motor cord port M1, M2 or M3.
– Remove obstacles around or underneath the tabletop that block its range of movement.
– Remove excess load on table.
See Troubleshooting Guide

Control boxes contain plug detection.
This means that the control box recognizes when a motor cord is connected to plug port M1, M2 and M3, and when a leg motor has been removed or replaced.
If a motor has been removed from a plug port, the control box will click three times.
If a programmable hand switch is used, the error code E36 (M1), E37 (M2) or E38 (M3) will be shown, depending on which leg motor was removed.
See Troubleshooting Guide 

This error code represents a connection error in the cascading network.
The error usually appears on the hand switch display for 15 seconds, then the control box goes into reset mode displaying zero(s) on the hand switch.
– Check all cord connections to the control box and perform the initialization (reset) procedure.
See Troubleshooting Guide

A factory reset returns the control box to its startup operational mode.
Basic Up/Down handswitch:
– Disconnect the control box from its power source
– While disconnected, press and hold the “up” and “down” buttons on the handswitch
– Reconnect the control box to its power source, continue pressing the “up” and “down” buttons on the hand switch until the control box clicks twice
The control box has now been reset to the factory settings.
Programmable handswitch:
Each step must be completed within 5 second intervals, or the factory reset will terminate and will have to start over.
– Press and hold the 1, 2, and “up” buttons simultaneously (for up to 10 seconds) until the display shows “S” and a number (ex: “S 5”)
– Press the “down” button on the hand switch until the display reads “S 0”
– Press the “S” button
The control box has now been reset to the factory settings.

These features can limit the movement area of a tabletop (container stop is below the table and shelf stop is above it).
– A Container Stop Position is saved in the lower half of a tabletop’s movement area. When set, the position will the the new lower limit position
– A Shelf Stop Position is saved in the upper half of a tabletop’s movement area. When set, the position will be the new upper limit position.

To program Container Stop and/or Shelf Stop Positions:
1. Move the desktop down or up to the desired position where a Container Stop or Shelf Stop is to be stored.
2. Press and hold the “up” and “down” buttons on the hand switch simultaneously until the control box clicks twice.
3. Release the hand switch

To deactivate Container Stop and/or Shelf Stop Positions:
1. Move the tabletop to any position in the lower half or upper half of the tabletop movement area to deactivate a Container Stop or Shelf Stop
2. Press and hold the “up” and “down” buttons on the hand switch until the control box clicks once
3. Release the hand switch
