ATTACH GANGING TUBE TO COLUMNS
Assemble using the M8-1.25 Tooth Lock Washer Nut
(2 per column). The maximum tightening torque for
these nuts is 15.8Nm (10 ft-lbs).
Repeat steps 1 and 2 for second set of columns,
top supports and ganging tube.
ASSEMBLY INSTRUCTIONS

ATTACH TOP SUPPORTS AND RAILS
TO COLUMNS
Ensure the mounting holes in the column remain
aligned with the corresponding holes in the beam
or independent beam.
Align the beam or independent beam to the top
support. Assemble using the M8x1.25 x 12mm
length screws (4 per column) and a T40 Torx
driver. Be aware that the mounting holes may
not be tapped. As they are inserted, the provided
M8x1.25 x 12mm length screws will form their
own fastening threads if none are already present.
An average fastening torque of 8Nm (6 lbs-ft) will
be required to initially engage the screw in the hole.
The maximum tightening torque for these screws
is 20Nm (15 lbs-ft). Repeat as necessary for
remaining columns.

OPERATION
INFORMATION
INITIALIZATION/RESET
The desk must be initialized/reset after any of the following:
- After assembly
- After disconnection from the power supply
- After any impact on the table top.
To initialize/reset, move the table to the lowest position by pressing the DOWN button on the handswitch until
the columns reach the lowest position. Press the DOWN button again until the table moves slightly down to
the machine zero point and back up to the operation zero point. Release the DOWN button. If the button is
released too soon, the table legs will not move up. Repeat the reset process.
The control box is programmed with a parameter le which controls the table legs’ lower and upper travel
limits. Under no circumstance should a control box from one table be moved to another.
NORMAL HANDSWITCH OPERATION (for all handswitch types)
By pressing the UP or DOWN buttons, the table will move up or down to the desired position. Once the
desired position is reached, let go of the UP or DOWN button. The table legs will stop once they reach
the lower or upper height limits.
PROGRAMMABLE HANDSWITCH OPERATION (optional)
This programmable handswitch is
equipped with a display for showing
the current table height in centimeters
or inches.
The handswitch also will display an error code if an error is detected by the control box. When an error
is detected, the display will show an error code “EXX,” instead of the current table height. To resolve the
error, see the Troubleshooting Section (p. 17-18 of this guide).
The programmable handswitch also has the ability to save up to four different height positions.
