Operating instructions model OLS-C20

31076041.03 08/2017 EN/DE/FR/ES

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

reected 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 oer an automatic adjustment so

that there is a wide eld 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 tted with dierent

process connections. These contain a glass prism and the electronics

responsible for the evaluation.

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 dened by their

technical performance limits and their materials. Improper use is dened

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 suciently 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 specied in the operating

instructions should be adhered to.

■

Do not operate the instruments in the immediate vicinity of strong

electromagnetic elds or in the immediate vicinity of equipment that

can be aected by magnetic elds (min. clearance 1 m).

■

The responsiveness of the instrument is preset and cannot be

adjusted.

■

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 dierent 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, rst 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.

3.5 Personnel qualification

WARNING!

Risk of injury should qualication be insucient

Improper handling can result in considerable injury and

damage to equipment.

▶

The activities described in these operating instructions

may only be carried out by skilled personnel who have

the qualifications described below.

Skilled personnel

Skilled personnel, authorised by the operator, are understood to

be personnel who, based on their technical training, knowledge

of measurement and control technology and on their experience

and knowledge of country-specic regulations, current standards

and directives, are capable of carrying out the work described and

independently recognising potential hazards.

4. Transport, packaging and storage

4.1 Transport

Check the switch for any damage that may have been caused by

transport.

Obvious damage must be reported immediately.

4.2 Packaging and storage

Do not remove packaging until just before mounting.

Permissible conditions at the place of storage:

Storage temperature: 0 ... 70 °C

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 xing 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 nish of the wall. Note:

with electropolished pipes, the minimum distance to the opposite

surface must be a minimum of 20 mm.
