MSD4 Vibration damper
Kit consists of: 8 vibration dampers 15 x 20 mm, 8 M5 cylinder head
screws with hexagon socket, 8 spring washers Mounting using MS-1100
The MSD4 vibration damper kit is recommend to be used for damping
vibrations and oscillations on the SLG440 For applications with higher
mechanical stresses, eg presses, punching machines, we recommend
the MSD4 kit In this way, the availability of the SLG440 is increased
Spacer MSD5
The kit consists of 2 spacers The spacers must be used in case of
vibrations
Integrated status indication
The SLG440 series is also available with integrated status indication
(red/yellow/green) installed onto the receiver (See ordering code)

²) In case of failure, the leakage current at the most flows to the OSSD
cable The downstream control element must recognise this state as
LOW A safety PLC must detect this state
³) resolution = beam di beam diameter 10 mm

The load induction generates an induced voltage during the
switch-off, which compromises the downstream components
(spark quenching element)

2.8 Functions
The system consists of a receiver and a transmitter For the described
functions, no further switching elements are required The diagnostic
and function selection takes place with a command device (key re-
lease), refer to the chapter on parameterisation
The system has the following features:
• Protective mode automatic
(automatic start after release of the protection zone)
• Restart Interlock (manual reset)
• Double acknowledgement/reset
• Contactor control (EDM)
• Beam coding A
• Blanking of movable objects
