Operating instructions
Safety light curtain
MSD4 Vibration damper
Kit consisting of: 8 vibration dampers 15 x 20 mm, 8 M5 cylinder head
screws with hexagon socket, 8 spring washers
The MSD4 vibration damper kit must be used for damping vibrations
and oscillations on the safety light curtain SLC 420 For applications
with higher mechanical stresses, eg presses, punching machines, we
recommend the MSD4 kit In this way, the availability of the safety light
curtain SLC 420 is increased
2.4 Destination and use
The SLC 420 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 protective enclosure with IP 69K protection class is suitable for
applications, which need to be cleaned permanently (default cleaning
procedure) A Goretex compensating membrane prevents fogging and
the penetration of liquids during high temperature fluctuations
If liquids with aggressive ingredients are used for cleaning,
please check whether the product used is compatible with the
material of the sensor (refer to chapter "Technical data")
The user must evaluate and design the safety chain in ac-
cordance with the relevant standards and the required safety
level
