Chapter 6 Installation and Wiring
Figure 68 shows a connection example of a 450L-B safety light curtain with two
universal plug-ins (catalog number 450L-APU-UN-8) to an SI safety relay
(catalog number 440R-S12R2).
Figure 68 - Connection Example
Figure 69 on page 104 is an example of a muting application that connects the
450L-E light curtain with a 5-pin transmitter plug-in (catalog number
450L-APT-PW-5) and an 8-pin receiver plug-in (catalog number
450L-APR-MU-8) to an SI safety relay (catalog number 440R-S12R12).
T-connector
If a safety light curtain system has an Rx and a Tx plug-in with M12 5-pin
connectors, then a T-connector can also be used to design and connect the system
(see Figure 69
).
