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.
