Two-sensor Muting with Muting Plug-in
Figure 74 is a two-sensor muting example with the 450L-E safety light curtain.
The transmitter uses the 5-pin transmitter plug-in, and the receiver uses the 8-pin
muting plug-in.
Figure 74 - Example Schematic for Two-sensor Muting of a 450L-E Light Curtain
The DIP switch settings for the receiver muting plug-in are shown in Tab le 50.
Switches 2, 3, 5, and 6 can be changed to ON, if needed by the application.
Switch 7 must be OFF and switch 8 must be ON. Switches 9, 10, and 11
determine the type of muting. The transmitter plug-in does not have DIP
switches.
