Commissioning and
configuration
How to align the safety light curtain:
Switch on the voltage supply of the safety light curtain.
During initial commissioning the COM LED flashes
White
and the two Twin-Sticks
establish communication
.
Align the two Twin Sticks such that LED 1 illuminates
Blue
.
The two Twin Stick start to communicate. During initial commissioning the COM LED
goes out
White
after the communication phase (approx. 3 s). The alignment can now
be optimised.
Align the two Twin Sticks with each other such that at least 3 and as many as possible
of the LEDs 1 to 5 illuminate
Blue
.
Fix the safety light curtain in place.
Once there is adequate alignment quality for 2 minutes, the system switches off the
alignment mode, the LEDs 1 to 5
Blue
go out.
If you wish to readjust the alignment later, switch the voltage supply of both Twin Sticks
off and back on again.
The host in a cascaded system continues to indicate red until all guests have been
correctly aligned, even if the host is correctly aligned.
If the maximum protective field width of 5 m is used, in some circumstances the system
may only indicate mediocre alignment quality with only 3 blue LEDs during alignment.
The system then still has a reserve of 30 %.
2)
During initial commissioning of a stick, the LED flashes immediately to signal initial synchronisation between
the sticks. During all further power up processes, the LED only flashes if the previous system partner does not
reply within 20 seconds. In this case the communication can also be established with a replacement stick.
