2. For Your Safety
2.1 Use for Intended Purpose
The product is based on the following functional principle:
Safety Light Curtain
The Light Curtain monitors the safety field between the emitter 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. However, the
correct overall function must be ensured by the system or machine manufacturer.
Use of the Light Curtain is only permissible if:
• Hazardous motion can be stopped by electrical means using the Light Curtain’s safety output
• 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 outside the danger zone for
machine operation.
• Regular safety inspections are carried out.
• Adequate detection of possible obstructions is assured with existing resolution
• The use of a light curtain, type 4 / Performance Level PL e / SIL 3 / SIL CL 3, was deemed permissible
following 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
• Other
• Construction industry

Safety Light Curtain 11
2.2 Use for Other than the Intended Purpose
• The product is not suitable for use in potentially explosive atmospheres.
• The product may only be used with accessories supplied or approved by wenglor, or in combination with
products approved by wenglor. A list of approved accessories and combination products can be accessed
at www.wenglor.com on the product detail page.
• The product is not suitable for use in outdoor weather.
DANGER!
Risk of personal injury or property damage in case of use for other than the intended
purpose!
Use for other than the intended purpose may lead to hazardous situations.
• Observe instructions regarding use for intended purpose.
2.3 Personnel Qualifications
• Suitable technical training is a prerequisite.
• In-house electronics training is essential.
• Trained personnel who use the product must have uninterrupted access to the operating instructions.
DANGER!
Risk of personal injury or property damage in case of incorrect initial start-up, opera-
tion and maintenance!
Personal injury and damage to equipment may occur.
• Adequate training and qualification of personnel.
2.4 Modification of Products
DANGER!
Risk of personal injury or property damage if the product is modified!
Personal injury and damage to equipment may occur. Non-observance may result in loss of
the CE mark and the guarantee may be rendered null and void.
• Modification of the product is impermissible.

2.5 Important Safety Precautions
2.5.1 Important Safety Precautions for Machine Manufacturers
DANGER!
Risk of safety device failure
If this warning is not observed, body parts and people to be protected may not be
detected.
• The national directives and safety regulations resulting from this application (e.g. accident
prevention) must be observed.
• A risk assessment must be carried out.
• Depending on the application, a check must be carried out to determine whether addition-
al protective measures are required.
• The safety light curtain and associated components must not be tampered with or modi-
fied.
• Light curtains must not influence each other. Different beam codings can be used where
required (see Section 7.1, page 109).
• No repair work may be carried out on the device and its components. An incorrect repair
could render the protection function ineffective.
2.5.2 Important Safety Precautions for Machine Operators
DANGER!
Risk of safety device failure
If this warning is not observed, body parts and people to be protected may not be
detected.
• If changes are made to the electrical integration in the machine control or the mechanical
installation of the safety light curtain, a new risk assessment must be carried out.
• The safety light curtain and associated components must not be tampered with or modi-
fied.
• No repair work may be carried out on the device and its components. An incorrect repair
could render the protection function ineffective.
2.6 General Safety Precautions
NOTE!
• These instructions are an integral part of the product and must be kept on hand for the
entire duration of its service life.
• In the event of possible changes, the respectively current version of the operating instruc-
tions can be accessed at www.wenglor.com in the product’s separate download area.
• Read the operating instructions carefully before using the product.
• Additional measures may be necessary in order to assure that the ESPE does not fail in a
dangerous fashion due to other types of light which are used in a special application
(e.g. emission due to welding sparks or the effects of stroboscope lights) (EN 61496-2,
Para. 7ff)

2.7 Approvals and IP Protection
RoHS
3. Product Description
The SEFG safety light curtain is a piece of electro-sensitive protective equipment (ESPE) used to safeguard
danger points, danger zones and accesses to machines.
The ESPE monitors the safety field between the emitter and the receiver.
When an object penetrates the safety field and one or multiple beams are interrupted, a switch command is
triggered on both safety outputs. Together with the downstream evaluation, this prevents a hazardous motion
from being initiated or interrupts an action that has already been initiated.
Objects that protrude into the safety field on the system side can be hidden in blanking operating modes.
The ESPE consists of the following components:
* On the emitter, the indicator lamp
has no lighting function
Indicator lamp*
Optics
(safety field)
Control panel
Connector plug
Emitter Receiver
