performed after mechanical installation of the light curtain. After the Light Array has been adjusted, it immediately
switches to the respectively selected operating state as soon as supply voltage is applied.
Emitter
Receiver
Pilot Beam
The pilot beam is used to synchronize the light curtain. It is the closest beam
to the display and may not be continuously interrupted.
The degree of alignment appears at the display during alignment.
The necessary degree of alignment depends on the distance between
transmitter and receiver (see table on page 18). If the necessary degree
of alignment has been achieved, this value must be accepted by means
of the Enter key.
5.1.1 Using the Aligning Tool RF
Reflector
The RF aligning tool is extremely helpful thanks to the use of
visible red light.
The function of the aligning tool is based upon the principle
of a reflector.
The arriving light beam is reflected back in exactly the same
direction from which it originated.
Procedure:
• Position the aligning tools at the top and bottom in front of the receiver.
• Observe the aligning tools from the transmitter (look from the transmitter to the receiver).
• Adjust the transmitter such that the reflected spot is situated at the centre of the respective RF aligning tool.
