Commissioning and calibrating
Please note the following procedure:
1.
Mounting with alignment of the light curtain
2.
Connection of the light curtain cable to the terminals provided for that purpose
3.
Connect the yellow wire of the cable to the bridge to the +24VDC terminal
4.
Keep the monitoring area free, especially beam 1
5.
Turn on the 24VDC supply voltage
6.
Disconnect the bridge between the yellow wire and +24VDC as long as the light cur-
tain is still connected to the supply voltage
=> The upper LED (LED1) at the receiver flashes once indicating that data are being
saved
7.
Check the functionality of the light curtain in the entire monitoring area using an
opaque object.
The calibration (items 3 to 6, yellow wire) is important for adapting the light curtain to the
specific application. You should, therefore, perform the calibration for availability following a
change to the application.
Notice!
Note that the monitoring area, especially beam 1 (the first beam starting from the side of the
connection cable) is free.
