1. General

1.1 Information Concerning these Instructions

• These instructions apply to the following multi-beam Safety Light Arrays:

– SEFB

– SEFB muting

– For the exact order designation, see “16.3 Order Notes” on page 158

• They make it possible to use the product safely and efﬁciently.

• These instructions are an integral part of the product and must be kept on hand for the entire duration of its

service life.

• Local accident prevention regulations and national occupational health and safety directives must be ob-

served.

• The product is subject to further technical development, and thus the information contained in these operat-

ing instructions may also be subject to change.

The current version can be found at www.wenglor.com in the product’s separate download area.

NOTE!

The operating instructions must be read carefully before using the product and must be kept

on hand for later reference.

1.2 Target Group

• These operating instructions are aimed at developers, planners, installers, owners and machine operators

who want to safeguard their systems with safety technology from wenglor sensoric GmbH (referred to in the

following as “wenglor”).

• The instructions are also aimed at qualiﬁed specialist personnel, who are commissioning the SEFB multi-

beam Safety Light Array for the ﬁrst time, maintaining it or integrating it in a machine with accessories and

additional products where applicable.

1.3 Explanations of Symbols

• Safety precautions and warnings are emphasized by means of symbols and attention-getting words.

• Safe use of the product is only possible if these safety precautions and warnings are adhered to.

The safety precautions and warnings are laid out in accordance with the following principle:

ATTENTION-GETTING WORD!

Type and source of danger!

Possible consequences in the event that the hazard is disregarded.

• Measures for averting the hazard.

Multi-Beam Safety Light Array 9

The meanings of the attention-getting words, as well as the scope of the associated hazards, are listed

below:

DANGER!

This word indicates a hazard with a high degree of risk which, if

not avoided, results in death or severe injury.

WARNING!

This word indicates a hazard with a medium degree of risk which, if not avoided,

may result in death or severe injury.

CAUTION!

This word indicates a hazard with a low degree of risk which, if

not avoided, may result in minor or moderate injury.

ATTENTION!

This word draws attention to a potentially hazardous situation which, if not avoided, may

result in property damage.

NOTE!

A note draws attention to useful tips and suggestions, as well as information regarding

efﬁcient, error-free use.

For Your Safety

2. For Your Safety

2.1 Use for Intended Purpose

The product is based on the following functional principle:

Safety light arrays

The light array monitors the safety ﬁeld between the transmitter and the receiver. If the safety ﬁeld is penetrat-

ed by an object, a switching command is triggered. This switching command may prevent initialization of a

hazardous machine motion, or may stop an action which has already been started.

As part of an overall system, the task of this product is to carry out safety-related functions. The correct over-

all function must be ensured by the system or machine manufacturer, however.

Use of this ESPE is only permissible if:

• The hazardous motion can be stopped electrically by the safety outputs of the ESPE.

• The safety clearance between the ESPE and a hazardous machine motion is complied with at all times.

• Additional mechanical safety equipment is installed so that the safety ﬁeld must be passed through to

access hazardous machine parts.

• Care is taken during installation to ensure that the personnel always remain inside the monitored zone for

machine operation.

• Regular safety inspections are carried out.

• Adequate detection of possible obstructions is assured with the existing number of beams.

• The use of a light array, type 4 / Performance Level PL e / SIL 3 / SIL CL 3, was deemed permissible follow-

ing an extensive risk analysis.

This product can be used in the following industry sectors:

• Special machinery manufacturing

• Pharmaceuticals industry

• Electronics industry

• Chemicals industry

• Heavy machinery manufacturing

• Clothing industry

• Glass industry

• Agriculture industry

• Logistics

• Plastics industry

• Steel industry

• Alternative energy

• Automotive industry

• Woodworking industry

• Printing industry

• Raw materials extraction

• Food industry

• Consumer goods industry

• Aviation industry

• Paper industry

• Packaging industry

• Construction industry

• Other
