Operating instructions
Safety light curtain / safety light grid
SLC 220
SLG 220
EN
The information contained in this operating instructions manual is pro-
vided without liability and is subject to technical modifications.
If multiple safety components are wired in series, the Per-
formance Level to EN ISO 13849-1 will be reduced due to the
restricted error detection under certain circumstances. The
entire concept of the control system, in which the safety com-
ponent 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 electro-sensi-
tive device does not present a dangerous breakdown, when other forms
of light beams are available in a special application (e.g. use of wireless
control devices on cranes, radiation of welding sparks or effects of
stroboscopic lights).
1.6 Warning about misuse
In case of inadequate or improper use or manipulations of the
safety switchgear, personal hazards or damage to machin-
ery or plant components cannot be excluded. The relevant
requirements of the standards EN ISO 13855 (successor of
EN 999) & EN ISO 13857 must be observed.
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.

2.2 Special versions
For special versions, which are not listed in the order code below 2.1,
these specifications apply accordingly, provided that they correspond to
the standard version.
2.3 Scope of delivery and accessories
Accessories included in delivery
Mounting kit MS-1000
The kit comprises 4 rotating mounting angles and 16 mounting screws
for fixing to the end caps.
Mounting kit MS-1010
Consisting of 2 centre supports (as from protected field ≥ 1075 mm).
Test rod PLS-01
The test rod is used for testing the protection field. The PLS-01 test rod
has a diameter of 30 mm.
Optional accessories
Safety relays
For processing the signal outputs OSSD 1 and OSSD 2 of the SLC/
SLG 220 series, the use of a safety relay is recommended. This safety
relay must meet the safety requirements for the chosen safety level.

BUS converter NSR-0700
Converter for parametrization and diagnostics. Detailled information can
be found in the operating instructions manual of the NSR-0700.
Included in delivery: integrated connecting cable, PC-software WIN 95,
98, NT, XP; RS 232 connection. (L x W x H, 122 x 60 x 35 mm)
MSD2 Vibration damper
Kit comprising: 8 vibration dampers 15 x 20 mm, 8x M5 socket head
cap screws, 8 spring washers. The MSD2 vibration damper kit must
be used for damping vibrations and oscillations on the SLC/SLG 220.
For applications with higher mechanical stresses, we recommend the
MSD2 kit. In this way, the availability of the SLC/SLG 220 is increased.
2.4 Destination and use
The SLC/SLG 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 accord-
ance with the relevant standards and the required safety level.
