general safety regulations for the instrument's range of use.
■
The operating instructions are part of the product and must
be kept in the immediate vicinity of the instrument and readily
accessible to skilled personnel at any time. Pass the operating
instructions onto the next operator or owner of the instrument.
■
Skilled personnel must have carefully read and understood the
operating instructions prior to beginning any work.
■
The general terms and conditions contained in the sales
documentation shall apply.
■
Subject to technical modifications.

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 integrated switch electronics offer an automatic adjustment so
that there is a wide field of application. For the output, there is an
O.C. pnp-transistor switching output or a relay switching output.
2.2 Instrument construction
Depending on the switch type, the instruments are fitted with
different process connections.These contain a glass prism and the
electronics responsible for the evaluation.

3. Safety
3. Safety
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 their 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!
■
The maximum power and voltage values as specified in the
operating instructions should be adhered to.

3. Safety
■
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 responsiveness of the instrument is preset and, with
models OLS-C20 and OLS-C29, cannot be adjusted. With
the models OLS-C01, OLS-C02, OLS-C04 and OLS-C05, the
responsiveness can only be adjusted if the switch is fitted with a
trimmer.
■
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.
