Control units
Control units for synchronous control of 1, 2, 3, or 4 lifting modules for
height-adjustable table systems.
1 lifting module EU; 230 V AC
USA/CDN; 120-277 V AC
2 lifting modules EU; 230 V AC
USA/CDN; 120-277 V AC
3 lifting modules EU; 230 V AC
USA/CDN; 120-277 V AC
4 lifting modules EU; 230 V AC
USA/CDN; 120-277 V AC
Basic function is up-and-down movement of the lifting modules.
Additional functions include storing of positions and moving into these
positions.
Operating time is 2 minutes "ON" and 18 minutes "OFF".
Control unit features
• Operating time limit:
The electronics monitor how long the lifting modules have been moving.
If the maximum permissible time is exceeded (operating time:
10% = 2 minutes ON, 18 minutes OFF), then the electronics will not
permit another movement. The control unit and lifting module are thus
protected from overload.
• Safety shut-off:
In the case of inadmissibly high heat, the control unit and lifting module
will shut off.
• Safety area:
The area 10 cm before the lower end position is defi ned as the safety
area.

If the lifting modules reach this point, they will stop and can be moved
again at a reduced speed after pressing the button again.

Press the "DOWN" button twice if the lifting module is to be moved
downward within the safety area and the previous movement was an
upward movement.
• Overload recognition:
The control recognizes if a table with lifting modules has a too-high
(weight) load and shuts off.
• Memory:
3 memory positions can be approached by the control unit (no auto
memory).
• External protection of objects and prevention of impacts:
A collision protection sensor or safety control strip can be connected
to the control unit. The control strip (3 842 540 129 + 3 842 540 130)
serves to protect objects and prevent impacts to avoid damage to
equipment – NO personal safety!
• Safety lock:
The table cannot be moved if the safety lock is activated. This prevents
uncontrolled movement of the table.

The safety lock is activated or deactivated by pressing the M button for
10 seconds.
