Lift 240
4.1 Function description
The lift table Lift 240 is used for leveling laboratory equipment (e.g.
glasses, flasks, Bunsen burners, etc.) when conducting scientific
procedures such as in a chemistry lab.
The scissor lift of the table device is powered by a 24V electric motor
with worm gear.
A laboratory unit placed on the lifting platform can be continuously
lifted by remote control or lowered.
The maximum lifting height may be limited by an adjusting wheel
fixation (see Section 0).
The remote control allows the of operating multiple lift tables via a
display selection. Each lift table must first be taught to its control
frequency (see Section 0).
The remote control has a power saving mode and is activated by
pressing the red button.

Transport
Operating manual (Serial number) Page 15 of 27
Lift 240
5 Transport
The lift table is secured in its packaging against damages during
transport.
Do not lift the lift table during transport by the lifting platform or
bellows. The bellows could be damaged. Hold the lift table by the
base during transport.
Attention!
Material damage and risk of injuries!
•Work carefully - hands and feet can be crushed
•When transporting the lift table, secure it against falling and
crashing.
•Secure loose equipment parts before transporting against falling.

6 Installation and startup
6.1 Assembly
6.1.1 Safety instructions for the installation
Attention!
Damage to the machine!
•Maintain a safe location for the device.
•Select a dry, level and slip-proof location.
•Watch for good ergonomics
•Make sure that no cables are pinched.
Warning!
Risk of tripping!
•Make sure that no loose cables or objects are located on the floor
in the work area.
•Place the device and the connections so that no one steps on it,
or drives or stumbles over it.
6.1.2 Procedure
•Select a suitable location
Power supply:
•Connect the power supply with the lift table (1) - Connection
pos (2).
•Plug the power cable (3) into the power supply. Plug the power
cable into a grounded socket.

Installation and startup
Operating manual (Serial number) Page 17 of 27
Lift 240
6.2 Startup
Switch the device on with the red toggle switch. The blue and red
LED flash very quickly.
Now press the bottom or top button of the remote control for about
3 seconds until the blue LED on the top or the red LED on the bottom
flashes more slowly.
Now you can traverse the lift platform by pressing the remote control
with the top button for up (UP) and with the lower knob for down
(DOWN).
6.3 Coordination for the radio frequency
Are each lift table must be adjusted for the signal detection of the
radio frequency of the remote control.
•For teaching, the upper or the lower button of the remote control
must be pressed sequentially for 3 seconds when the lift table is
switched on.
The blue (1) or red (2) LED at the base of the lift table flashes during
the teach-in in quick succession.
If the motor controller has detected the appropriate signal, the blue
and red LED flash more slowly. The unit is operational.
•Lift and lower the lift table for a trial without a load.
The lift table moves until the upper or lower button of the remote
control is pressed or until the maximum or minimum position is
reached. A brief, inadvertent contact with the control buttons has no
effect.
Note
When operating several lift tables, it is recommended to number
the individual lift tables, for example, with labels to prevent any
mix-ups and therefore accidents.

6.4 Setting the end stop
Figure. 3 Setting the end stop
In order to adjust the end stop of the lift platform, the lateral surface
knurled nut (1) must be loosened. The slide can now be adjusted in
direction "- " or "+".
The slide is now locked in place by tightening the knurled nut.
When adjusting the slide to the stop in direction "+", the maximum
height of the lift platform is reached. Shifting in direction "-" limits the
height.
You need a measuring tape or yardstick to determine the upper
endpoint.
Raise the loaded lift platform by pressing the blue button on the
remote control until the desired height is reached.
Is the desired height is reached, shift the slide until it audibly snaps
into place. Now tighten the thumbscrew. The end stop is now
adjusted.
Based on the design, the lift platform can be lowered somewhat
further when reaching of minimum height by pushing the lift platform
manually down.
