Beam coding of two safety light curtains
– If two safety light codes are to be used in parallel, a beam coding of the safety light
curtains is recommended. When connecting the safety light curtain to the supply
voltage, the safety light curtains are connected to different pins. This guarantees a dif-
ferentiation of the beams, and transmitter and receiver can not interfere with each
other.
If several adjacent safety light curtains need to be
installed, steps must be taken to ensure
that the transmitter on one safety light curtain
does not interfere with the receiver on an-
other safety
light curtain.
