SICK MSL
8 007 653/09-04-01 Technical Description • MSL © SICK AG • Safety Systems • Germany • All rights reserved
The position of the light beams is
indicated by a marking on the
housing.
Synchronisation between sender
unit and receiver unit is achieved
optically, by means of a pre-defined
encoded sequence, thus eliminating
the need for galvanic connection
between sender and receiver.
The MSLZ variant
The MSLZ light barrier, like the MSL
is a contactless protection
installation – but with one passive
side and one active side (
fig. 2). It is
suitable for access control and
danger zone protection with a pas-
sive mirror side, and a maximum
distance of 7.5 m. The MSLZ fulfils
the pr EN 50 100 (pr EN 61 496)
regulations, safety category 4.
2.2 Intended use of the
device
The MSL multibeam safety light barrier
may only be used as specified in
section
2.1, Areas of use of the device.
If it is used in any other way, or if it is
modified in any way – including during
installation and mounting – SICK AG
shall not be held liable for any
warranty claims arising.
2.3 General safety instructions and precautions
1
Installation, commissioning, use and
routine technical checking of the
non-contact safety device is sub-
ject to national and international
regulations and standards, in
particular:
‡ Regulations derived from the
Machinery Directive 98/37
EC
‡ Regulations derived from the
Use of Equipment Directive
89/665 EEC
‡ Relevant safety regulations
‡ Applicable accident
prevention regulations and
safety rules.
The manufacturers and users of
the machinery on which our safety
devices are used are solely
responsible for ascertaining all
applicable safety standards and
regulations from the competent
authorities and for ensuring
compliance with those standards
and regulations.
2 Furthermore,
the instructions
laid down – and
in particular
the test requirements
(see
Testing) set out in this
Technical
Description
and in the
Operating
Instructions
(including instructions
relating to use, mounting, instal-
lation and integration into the
machine control system) – must be
followed.
3
The tests must be performed
by
qualified experts
or by
authorized and competent
personnel
and must be
documented in such a way as to
be verifiable at any time.
4
The Operating Instructions
must
be made available to

device is used. The employee
must be instructed
by qualified
experts.
5
The test protocol according to the
use of the non-contact safety
device is printed at the end of
this
Technical Description
.
Acceptance testing is performed
on the basis of that protocol.
The active side contains the sender
and receiver elements with a beam
gap of 500 mm (
fig. 2). The passive
side is realised with corner mirrors.
The following key specifications are
valid for the MSLZ:
