1.4 Appropriate use
The products described in these operating instructions are developed to
execute safety-related functions as part of an entire plant or machine. It
is the responsibility of the manufacturer of a machine or plant to ensure
the correct functionality of the entire machine or plant.
The safety switchgear must be exclusively used in accordance with the
versions listed below or for the applications authorised by the manufac-
turer. Detailed information regarding the range of applications can be
found in the chapter "Product description".
1.5 General safety instructions
The user must observe the safety instructions in this operating instruc-
tions manual, the country-specific installation standards as well as all
prevailing safety regulations and accident prevention rules.
Further technical information can be found in the Schmersal
catalogues or in the online catalogue on the Internet:
www.schmersal.net.
The information contained in this operating instructions manual is pro-
vided without liability and is subject to technical modifications.
The entire concept of the control system, in which the
safety component is integrated, must be validated to
EN ISO 13849-2.
There are no residual risks, provided that the safety instructions as well
as the instructions regarding mounting, commissioning, operation and
maintenance are observed.
Additional measures could be required to ensure that the system does
not present a dangerous breakdown, when other forms of light beams
are available in a special application (e.g. use of wireless control de-
vices on cranes, radiation of welding sparks or effects of stroboscopic
lights).
1.6 Warning about misuse
In case of improper use or manipulation of the safety switch-
gear, personal hazards or damages to machinery or plant
components cannot be excluded when safety switchgear is
used. The relevant requirements of the standards
Only if the information described in this operating instructions
manual are realised correctly, the safety function and therefore
the compliance with the Machinery Directive is maintained.
1.7 Exclusion of liability
We shall accept no liability for damages and malfunctions resulting from
defective mounting or failure to comply with this operating instructions
manual. The manufacturer shall accept no liability for damages result-
ing from the use of unauthorised spare parts or accessories.
For safety reasons, invasive work on the device as well as arbitrary re-
pairs, conversions and modifications to the device are strictly forbidden;
the manufacturer shall accept no liability for damages resulting from
such invasive work, arbitrary repairs, conversions and/or modifications
to the device.
2. Product description
2.1 Destination and use
The SLC/SLG440COM is a non-contact, self-testing safety guard which
is used for the protection of hazardous points, hazardous areas and
machine accesses. If one or more light beams are interrupted, the
hazardous movement must be stopped.
The user must evaluate and design the safety chain in
accordance with the relevant standards and the required
safety level.
