1 General Information
This document contains necessary information for the proper installation and use of this
device. In addition to this instruction, be sure to observe all statutory requirements, appli-
cable standards, the additional technical specifications on the accompanying data sheet
(see www.labom.com) as well as the specifications indicated on the type plate.
1.1 General Safety Notes
The installation, set up, service or disassembly of this device must only be done by
trained, qualified personnel using suitable equipment and authorized to do so.
Warning
Media can escape if unsuitable devices are used or if the installation is not
correct.
Danger of severe injury or damage
Ensure that the device is suitable for the process and undamaged.
1.2 Intended Use
The device is suitable for measuring the filling level as specified in the data sheet.
1.3 Conformity with EU Regulations
The CE-marking on the device certifies its compliance with the applicable EU Directives for
placing products on the market within the European Union.
2 Transportation and Storage
Store and transport the device only under clean and dry conditions preferably in the origi-
nal packaging. Avoid exposure to shocks and excessive vibrations.
Permissible storage temperature: -20…70 °C
3 Installation and Commissioning
Ensure that the device is suitable for the intended application with respect to pressure
range, overpressure limit, media compatibility, temperature range and process connection.
3.1 Mechanical Installation
For installation use only approved sleeve clamps and adapters. Installation in non-Labom
systems can result in incorrect function and leakage.
The thread of the devices must be electrically connected with the threaded sleeve and the
metallic container.
Insulating seals of Teflon or paper are not suitable for correct, error-free operation.
The tightening torque must be between 5 and 10 Nm when screwing the device into the
sleeve.
With non-metallic containers, a threaded sleeve with a diameter of at least 28 mm must be
used.
If the device is opened there is a risk of influencing the signals by touching the electronic
connections. This can be avoided by switching off the supply voltage or disconnecting the
signal circuit.

3.2 Electrical Connection
Complete the mechanical installation before you connect the device electrically.
Set up all electrical connections while the voltage supply is switched off.
Figure 1: electrical connection
Connect power supply to terminals 1 (+) and 2 (-). The casing is electrically connected to
terminal 2.
Set the signaling function via the configuration switch:

output triggered when covered with product
1
output triggered when not covered with product
A bi-color LED indicates the system status:
green
device ready
red
output ON
An ON output is available at terminal 3 (high signal). The output is 50 mA max. and is
short-circuit-proof.
3.3 Sensitivity adjustment and delay
Sensitivity and delay can be adjusted either via the configuration DIP switches or alterna-
tively using the optional programming set.

4 Operation
During operation, take care that the device remains within its intended pressure and tem-
perature ranges. No other monitoring is necessary.
Permissible media temperature: 0…100 °C
Permissible ambient temperature: -10…60 °C
4.1 Maintenance / Service
When properly installed in accordance with applicable specifications, this device is
maintenance-free. However, we recommend an annual recalibration of the device.
In the event of any damage or defect the customer cannot replace or repair any compo-
nents or assemblies.

5 Disassembly
When measuring hot media, make sure that the device has cooled down prior to any dis-
mounting or wear appropriate protective clothing to avoid burns.
Switch off the power supply to the device before disconnecting the electrical connections.
Once this is done, the device may be mechanically removed.
Warning
Opening pressurized lines might cause severe injuries.
Danger of severe injuries or damage
Relieve the process pressure before attempting to remove the device.
Shut off the pressure supply for all feed lines to the device and relieve the
pressure in them.
Warning
Hazardous deposits and residues might remain on opened process connec-
tions and removed devices.
Danger of injury
After the device has been removed, seal off the measuring point and
mark the open process connection accordingly. Consider a possible dan-
ger due to residues when handling the removed device.
