Battery Monitoring
The battery monitor unit built into the control cabinet door is used to indicate and monitor the battery status
of the two lead-acid batteries that are used to supply power to the Mobile Lifter.

With the two buttons (
+
) and (
-
) you can switch between the fol-
lowing display modes:
- Charge status in percent (
%
)
- Battery voltage (
V
)
- Estimated operating time in hours (
h
)
•
The unit emits an acoustic warning beep as soon as the batteries
need to be recharged (for charging procedure see
•
To save the batteries, the unit has an integrated deep discharge
protection, which switches off the power for the Mobile Lifter as
soon as the battery voltage falls below a critical value.
•
Remark:
The unit has already been set correctly at the factory.
Therefore, do not make any changes to the settings.

Vacuum Clamping Device with Pressure Switch
With the vacuum clamping device, panels to be transported can be fixed quickly and safely.

•
The heart of the system is the vacuum unit (
2
) shown in
Figure 15, including the electric vacuum pump.
These components are located in the blue housing between the two batteries.
•
The six vacuum pads (
8
) shown in
Figure 16 are used to fix the panel material to be clamped. The outer
four vacuum pads (

) can be manually adjusted to the size of the panel to be clamped. The detailed proce-
dure for adjustment can be found in the section
•
The digital pressure switch (
12
) shown in
Figure 17 controls the vacuum pump and indicates the current
operating vacuum (between 0.3 and 0.9 bar). If the vacuum falls below 0.25 bar, the red warning lamp (
10
)
lights up until the digital pressure switch has restored the operating vacuum.
Remark:
Do not change the
settings of the digital pressure switch, it has already been optimally adapted to the system at the factory.
•
The vacuum pump must not be operated with the housing cover open or on a wet or damp
surface. There is a risk of short-circuit with increased risk of electric shock!
•
Maintenance and repair work on the vacuum pump may only be carried out by authorised
electricians in accordance with the electrical regulations.
•
In the event of a power failure and/or failure of the vacuum pump, there is a risk of a fall-
ing load. Therefore, generally wear safety shoes!
The ingress of liquids (e.g. coolants or lubricants) can damage the vacuum pump and reduce the
adhesion of the plate. If necessary, connect a liquid separator between the pump and the clamp-
ing device and always ensure that the vacuum pads are firmly seated.
