Chapter 5 System Configuration
The universal plug-in can be set to perform as an emitter or receiver. If pins 4
and 8 of the connectors are short circuited at power-up, the stick behaves like a
transmitter. In this case, the DIP switches have no functionality. Also, the
beam coding functionality is still set at the 450L-E Receiver (Rx). For the
confirmation of the beam coding configuration and the pairing procedure, see
Confirmation of a New System Configuration on page 59 . If pin 4 and pin 8 of
the plug-in are not short circuited at power-up, the corresponding stick
behaves like a receiver. In this case, the DIP switches have the same
functionality as the 450L-APR-ED-8 receiver plug-in.
Receiver Plug-in DIP Switch
Settings
The transmitter plug-ins and the cascading plug-ins don’t have DIP switches.
Identify and set the appropriate DIP switches for the configuration desired.
Figure 32 shows DIP switch identification. The number of DIP switches varies
depending on the plug-in type.

After installing the plug-in on the 450L-B safety light curtain transmitter stick
and power-up, a configuration confirmation can be performed (signaled by
the red/ green blinking of the STS status indicator). The confirmation of the
configuration can be performed without the receiver and transmitter aligned.

(1) The 8-pin M12 for the transmitter is simply for the convenience of specifying two 8-conductor cordsets for the system.
(2) IR is always enabled in 450L PAC models, this is not user configurable.
IMPORTANT DIP switches must be switched to OFF if the Switch Function is not
defined. Otherwise, an error condition occurs (see
Status Indicator
Error Display on page 103 ).
After each reconfiguration of a safety light curtain, test the system for
proper configuration and operation before placing the guarded
machine in operation.
ATTENTION: Every modification of the DIP switches must be confirmed with a
configuration confirmation procedure after the first power-up (see
Confirmation of a New System Configuration on page 59 ).
