6.2 Aligning sender and receiver
After the light curtain has been mounted and connected, the sender and receiver must be
aligned precisely in relation to each other.
How to align sender and receiver in relation to each other:
Secure the plant/system. No dangerous movement possible!
Make sure that the dangerous state of the machine is (and remains) switched off! During
the alignment process, the outputs of the safety light curtain are not allowed to have any
effect on the machine.
⋅ Loosen the clamping bolts which hold the light curtain in place.
⋅ Switch on the power supply to the light curtain.
⋅ Watch the alignment information on the 7-segment display of the receiver (see Tab. 13).
Correct the alignment of the sender and receiver, until the 7-segment display goes off.
⋅ Using the clamping bolts, fix the light curtain in place.
⋅ Switch the power supply off and then back on again and check via the 7-segment
display whether the alignment is correct after tightening the clamping bolts (Tab. 13).
