– The system architect is responsible for the safety of the system.
– The system architect undertakes to perform a risk assessment and to create documentation in
accordance with legal and normative requirements to be provided to the operator and user of
the system. This documentation must contain all necessary information and safety instructions
for the operator, the user and, if applicable, for any service personnel authorised by the
architect of the system.
• Read this document before setting up the product and keep it during the entire service life.
• The product must be suitable for the corresponding applications and environmental conditions
without any restrictions.
• Only use the product for its intended purpose ( Intended use).Ò
• If the operating instructions or the technical data are not adhered to, personal injury and/or damage
to property may occur.
• The manufacturer assumes no liability or warranty for any consequences caused by tampering with
the product or incorrect use by the operator.
• Installation, electrical connection, set-up, operation and maintenance of the product must be
carried out by qualified personnel authorised by the machine operator.
• Protect units and cables against damage.
• Only use the product for permissible media ( Technical data).Ò
• The unit complies with the standard EN 61000-6-4 and is a class A product. The unit may cause
radio interference in domestic areas. If interference occurs, the user must take appropriate actions.

5 Installation
Vertical installation from the top is preferred.
5.1 Device with single probe
For a safe function, the device requires a launching plate.
The following minimum distances between the rod and tank walls, objects in the tank (B), tank bottom
and other level sensors must be adhered to:
50mm
10mm
100mm
B40mm
For tank walls which are not straight, steps, supports or other structures in the tank a distance of 50
mm to the tank wall must be adhered to.
When operating the device in small tanks (rod lengths shorter than 200 mm and less than 300 mm
distance to the tank wall), mount the device off-centre (eccentrically) to prevent possible interference
from tank resonances.
For probe lengths > 70 cm the rod can be considerably deflected by movement of the medium. To
avoid contacting the tank wall or other structures in the tank in such cases, the minimum distances
should be increased. Reference values:
Probe length Distance to the tank wall or structures in the tank
70...100cm 100mm
100...160cm 180mm
If the medium is highly polluted, there is the risk that a bridge forms between the rod and the tank wall
or structures in the tank. To avoid incorrect measurements: adhere to increased minimum distances
depending on type and intensity of the soiling.
For installation in pipes:
• The inside pipe diameter (d) must be at least 100 mm (Fig. Installation on a pipe).
• If possible, mount the device off-centre (eccentrically).
• Only install the device in metal pipes.
For installation in a boss:
• The diameter of the boss (d) must be at least 60 mm (Fig. Installation in a boss).
• The height of the boss (h) must not exceed 40 mm (Fig. Installation in a boss).

Substances such as screw retaining compounds may migrate into the medium.
uMake sure that they are harmless.
When using mechanical means of securing (e.g. tooth lock washer), protruding edges must be
avoided. They may cause interference reflection.
5.3.2 Installation of the coaxial pipe
This chapter is only relevant if the device is to be operated with a coaxial probe.
The coaxial pipe and the rod must be of the same end length. The coaxial pipe can be
shortened.

uScrew the rod to the device and tighten it.
Tightening torque:4 Nm.
uSlide the sensor seal (A) onto the thread.
uSlide the coaxial pipe (B) onto the rod. Carefully centre it and
carefully move the rod through the centring piece (C) – for lengths
>140 cm through both centring pieces – of the coaxial pipe. Do not
damage the centring pieces.
uScrew onto the sensor thread and tighten.
5.4 Shortening of the probe
5.4.1 Shortening of the rod and determination of its length L
The rod can be shortened to adapt to different tank heights.
Ensure that the probe length is never below the minimum permissible length (L min) of 10 cm! The
device does not support probe lengths below 10 cm. If shorter probes are used, measurement
errors can occur.
Lmin
L
uScrew the rod to the device.
uMark the desired length (L) on the rod. The reference point is the
lower edge of the process connection.
uRemove the rod from the device.
uShorten the rod at the mark.
uRemove all burrs and sharp edges.
uScrew the rod to the device again and tighten it.
Tightening torque:4 Nm.
uPrecisely measure the probe length L and note the value. It must be
entered during parameter setting of the device.
5.4.2 Shortening of the coaxial pipe
The coaxial pipe and the rod must be of the same end length:
