2.3 Destination and use
In combination with the SLB200-C04-1R safety-monitoring module, the
SLB 200-E/R31-21 one-way safety light barriers are a non-contact safe-
ty guard (ESD, electro-sensitive device) for the protection of hazardous
areas on power-driven work equipment.

3. Mounting
3.1 General mounting instructions
• The light barriers can be operated in any mounting position (with or
without BF 31 mounting angle). The mounting possibilities are shown
on the dimensional drawing.
• The transmitter and the receiver must be fitted parallel to each other
and at the same mounting height.
• Turn the transmitter whilst observing the display of the receiver and fix
the point at which the LED indication changes from red to green.
• Calculate the max. left and right angle of rotation. Fix the fixing screws
in central position.
• Make sure that the LED indication does not flash red-green or change
to red continuous signal during this process.
Please also observe the notes for the calculation of the
safety distance in the operating instructions manual of
the SLB 200-C04-1R safety-monitoring module.
