Chapter 5 System Configuration
Confirmation of a New
System Configuration
Perform a confirmation procedure of a new configuration when you reinsert
the plug-in to the light curtain stick with a changed DIP switch setting. The
request for such a confirmation is displayed via a 1 Hz red/green blinking STS
status indicator (
Figure 33 ).
This process must be performed only once, after the first power-up of a plug-in
with new settings. It is not required at any following power-up (only when DIP
switches are changed again).

Confirmation
Figure 34 shows the configuration timing sequence. The optical push button
must be activated two times for 5 seconds. Between the two activations, a
break of a maximum of 2 seconds is allowed.

Confirmation Procedure
To confirm a new configuration, follow these steps:
1. The status indicator STS blinks green/red (1 Hz, one time red, and one
time green per second, 50:50 duty cycle) which indicates that the stick is
in the configuration mode.
2. Actuate the optical push button for 5 seconds.
3. STS blinks green/red to indicate actuation with a frequency of 10 Hz and
50:50 duty cycle.
IMPORTANT The confirmation procedure is not required when the receiver stick is
operated for the first time (brand new receiver). The STS status
indicator flashes red/green when a confirmation is required.
Confirmation of a system configuration must only be performed when
the receiver stick was previously operated with another configuration
or when the receiver stick was previously operated with another
transmitter.
If the receiver plug-in is exchanged with a new plug-in with the same
plug-in type and DIP switch settings as the original one, no confirmation
procedure is required.
Also, no configuration confirmation procedure is required for a
complete pair of 450L safety light curtain transceiver sticks out-of-the-
box.
