Configuration Process
1. The status indicator STS is green, which indicates normal operation (no
fault).
2. Actuate the optical push button (
) for 5 seconds.
3. The STS remains continuously green.
4. Once the status indicator STS starts green/off blinking, release the
optical push button.
5. Release is indicated with a change of frequency 10...1 Hz (status indicator
STS green/off and a 50:50 duty cycle).
6. Within 2 seconds, actuate the optical push button.
7. The status indicator STS indicates the activation by a green/off and the
status indicator BLK indicates the activation by an orange/off frequency
of 10 Hz and a 50% duty cycle.
8. Actuate the optical push button for at least for 5 seconds.
9. Once the status indicator and the blanking indicator changes frequency
10...1 Hz, release the optical push button.
10. After releasing the optical push button, the status indicator STS is steady
green and the BLK indicator continues blinking for 5 seconds (orange/
off).
11. In these 5 seconds, remove your hand and all objects that are not being
taught.
12. At the end of these 5 seconds, the 450L-E safety light curtain teaches all
interrupted beams.
13. A successful Teach-in is indicated with a 3 second blinking of the BLK
indicator (orange/off) and STS green on.
14. A failed Teach-in is indicated with a 3 second blinking of the BLK
indicator (orange/off) and the STS indicator (green/red).
IMPORTANT
If there is an error in the Teach-in procedure, the new fixed blanking
zone limits are not accepted and the light curtain continues working
with the previously taught zone limits.
Once the configuration confirmation procedure is completed, verify the
changed resolution.
