General safety notes
DANGER
If the safety component is integrated incorrectly, the dangerous state may be ended to
late.
b
Plan the integration of the safety component in accordance with the machine
requirements,
see "Project planning", page 12
.
2.2
Intended use
When used in conjunction with a suitable external test device, the L25 single-beam
photoelectric safety switch is a Type 2 electro-sensitive protective device (ESPE) in
accordance with IEC 61496-1 and IEC 61496-2.
The external test device must satisfy the applicable requirements for a type 2 device in
accordance with IEC 61496-1 and IEC 61496-2. Suitable test devices include, for
example, all SICK safety controllers that allow a single-beam photoelectric safety switch
to be connected, e.g., Flexi Soft or Flexi Classic. A single-beam photoelectric safety
switch in combination with an external test device can be used in safety applications up
to Category 2 according to EN ISO 13849, SILCL1 according to EN 62061 or up to PL c
according to EN ISO 13849.
The single-beam photoelectric safety switch is suitable for the following applications:
•
Access protection
•
Hazardous area protection
The single-beam photoelectric safety switch does not emit any paint wetting impairment
substances or volatile silicones and does not expel any fixed parts or materials into its
surroundings.
The single-beam photoelectric safety switch must only be used within the limits of the
prescribed and specified technical data and operating conditions at all times.
Any instance of improper use, incorrect modification, or manipulation of the L25 single-
beam photoelectric safety switch shall void any warranty provided by SICK AG; further‐
more, SICK AG shall not accept any responsibility or liability for any resulting damage
and consequential damage.
2.3
Improper use
The single-beam photoelectric safety switch works as an indirect protective measure
and cannot provide protection from pieces thrown from application nor from emitted
radiation. Transparent objects are not detected.
Among others, the single-beam photoelectric safety switch is
not
suitable for the follow‐
ing applications:
•
Outdoors
•
Underwater
•
In explosion-hazardous areas
•
In environments with increased levels of ionizing radiation
2.4
Requirements for the qualification of personnel
The protective device must be configured, installed, connected, commissioned, and ser‐
viced by qualified safety personnel only.
