NOTICE
Avoid interaction between single-beam safety light barriers and between cascades
i
Ä If multiple single-beam safety light barrier pairs are used, the aperture angle of the sensors
must absolutely be noted in order to prevent interaction.
Ä If the transmitter is only installed on one side, the light beams must not overlap on the re-
ceiver side so that the light beam of the transmitter reaches two receivers.
Ä With reciprocal installation of the transmitter and receiver, ensure that the light beam of
transmitter S1 cannot be received by receiver R3 and that the light beam of transmitter S3
cannot be received by receiver R1.
