systems are certified to ISO 9001 and ISO 14001.

■

These operating instructions contain important information on

handling the instrument.Working safely requires that all safety

instructions and work instructions are observed.

■

Observe the relevant local accident prevention regulations and

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

3.1 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.
