2. Design and function
2.1 Description
This instrument is used for the
detection of limit levels in liquids. The
measuring principle is independent
of refractive index, colour, density,
conductivity and dielectric constant.
The switches consist of an infrared LED
and a phototransistor. The light of the
LED is directed into a prism. So long as
the sensor tip of the prism is in the gas
phase, the light is reflected within the
prism to the receiver. When the liquid
in the vessel rises and wets the glass
tip, the infrared lightbeam into the liquid
is interrupted and only a small portion
reaches the receiver.
The optoelectronic sensor OLS-F1 was specifically designed for
sanitary applications and is suitable for a wide range of applications.
Autoclavable applications can be performed up to a temperature of
134 °C.
2.2 Instrument construction
The instruments are fitted with different hygienic process
connections. These contain a glass prism and the electronics
responsible for the evaluation with an O.C. PNP transistor output.
The electrical connection is made via a 4-pin M12 circular connector.
With the connector version, the sensor can be covered with the
included protection cap to enable cleaning in the autoclave at
saturated steam conditions of 134 °C.

3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can
result in serious injury or death, if not avoided.
Information
... points out useful tips, recommendations and
information for efficient and trouble-free operation.
3.2 Intended use
The optoelectronic level switches should only be used for level
control or monitoring of liquid media. Their scope of application
is defined by their technical performance limits and materials.

Improper use is defined as any application that exceeds the technical
performance limits or is not compatible with the materials. Checking
against improper use is the responsibility of the operator.
■
The liquids must not have any large contamination or coarse
particulates and must not have a tendency to crystallise. Ensure
that the wetted materials of the switch are sufficiently resistant to
the medium being monitored. Not suitable for dispersion, abrasive
liquids, highly viscous media and colours.
■
This instrument is not permitted to be used in hazardous areas!
Do not use in zone 1 or 2 hazardous areas.
■
The maximum power and voltage values as specified in the
operating instructions should be adhered to.
■
Do not operate the instruments in the immediate vicinity of strong
electromagnetic fields or in the immediate vicinity of equipment
that can be affected by magnetic fields (min. clearance 1 m).
■
The switches must not be exposed to heavy mechanical strain
(impact, bending, vibration).
The instrument has been designed and built solely for the intended
use described here, and may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.

3.3 Improper use
WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous
situations and injuries.
▶
Refrain from unauthorised modifications to the
instrument.
▶
Do not use the instrument within hazardous areas.
Any use beyond or different to the intended use is considered as
improper use.
Do not use this instrument in safety or emergency stop devices.
3.4 Responsibility of the operator
The instrument is used in the industrial sector. The operator is
therefore responsible for legal obligations regarding safety at work.
The safety instructions within these operating instructions, as well
as the safety, accident prevention and environmental protection
regulations for the application area must be maintained.
To ensure safe working on the instrument, the operating company
must ensure
■
that the operating personnel are regularly instructed in all topics
regarding work safety, first aid and environmental protection
and know the operating instructions and in particular, the safety
instructions contained therein.
■
that the instrument is suitable for the particular application in
accordance with its intended use.

5. Commissioning, operation
When unpacking the switch, check all components for any external
damage. Prior to installation, a functional check can also be carried
out. For this, the instrument should be connected temporarily and the
glass prism dipped in and out of a glass of liquid to test it.
5.1 Mounting
■
Before installation, it must be ensured that the mounting hole
and the fixing device for the switches in the vessel are correct in
size and dimension.
■
Mount the switch, pressure-sealed, into the process
connection.
■
Following installation, the glass tip should have a distance of at
least 10 mm to the opposite wall. This minimum clearance can
vary dependent upon the geometry and surface finish of the wall.
Note: with electropolished pipes, the minimum distance to the
opposite surface must be a minimum of 20 mm.
