Any use other than that defined under "Intended use" or which goes beyond that use is
considered improper use.
In particular, use of the device is not permitted in the following cases:
• Rooms with explosive atmospheres
• As stand-alone safety component in accordance with the machinery directive
• Operation for medical purposes
NOTICE
Do not modify or otherwise interfere with the device.
Do not carry out modifications or otherwise interfere with the device.
The device must not be tampered with and must not be changed in any way.
The device must not be opened. There are no user-serviceable parts inside.
Repairs must only be performed by Leuze electronic GmbH + Co. KG.
2.3 Competent persons
Connection, mounting, commissioning and adjustment of the device must only be carried
out by competent persons.
Prerequisites for competent persons:
• They have a suitable technical education.
• They are familiar with the rules and regulations for occupational safety and safety at
work.
• They are familiar with the technical description of the device.
• They have been instructed by the responsible person on the mounting and operation
of the device.
Safety
1)
Certified electricians
Electrical work must be carried out by a certified electrician.
Due to their technical training, knowledge and experience as well as their familiarity with
relevant standards and regulations, certified electricians are able to perform work on electrical systems and independently detect possible dangers.
In Germany, certified electricians must fulfill the requirements of accident-prevention regulations BGV A3 (e.g. electrician foreman). In other countries, there are respective regulations that must be observed.
1) Use as safety-related component within the safety function is possible, if the component combination is designed correspondingly by the machine manufacturer.

Device description
4 Device description
4.1 General information
The central part of the unit is an optical sensor that generates a horizontal band of light
(figure 3.1). The band of light illuminates a CCD line array camera. This CCD array produces
an output signal that depends on the number of illuminated pixels.
The system has a permanent calibration and guarantees maximum precision and stability
at all times.
Every sensor features two interfaces (see figure 3.1).
1. Interface P (RS 232):
programming interface for configuring the measurement modes and for visualizing the
measurement values.
2. Interface M12 (process interface):
data for the control system are transmitted via this interface. Depending on the device
model used, the measurement values are output either as an analog current/voltage
signal or as digital, serial information (RS 232, RS 422).
Depending on the device model used, not all measurement values are available at the P and
M12 interfaces:
• The analog interface can only output one measurement value at a time.
• The digital interface can transmit any number of measurement values.
