6.1
Commissioning
Prior to commissioning, the appropriate operating mode for the respective application case must be set via the DIP switches in
the terminal strip compartment (refer to Section 3.6). When delivered, the operating mode
with restart interlock, contactor
check and equivalent outputs
is pre-set . The electrical connection must be made according to the selected operating mode.
(refer to chapter 5).
6.1 Adjustment information
The visual alignment is advantageously carried out with intensely dimmed ambient lighting in order to be able to better detect
the LED indications of the receiver even from a long range.
When aligning, it must be ensured that the housings do not become distorted.
An
adjustment laser
can be obtained for the precise alignment of the ULVT/BLVT light
barriers, particularly where large distances are involved. The device is attached to the front
panel of the transmitter and receiver. When the button is pressed, the laser produces a red
light spot which can also be seen from long distances. The light spot must hit the centre of the
opposite device. This test should be performed at both ends of the transmitter and receiver.
The arrangement must be adjusted if necessary.
Adjustment with operation via tilted mirrors:
Place the adjustment laser onto the front
panel of the transmitter, switch it on and swivel the transmitter until the light spot hits the
centre of the mirror. Then adjust the mirror so that the light spot also hits the centre of the
second mirror / receiver.
Adjustment LED:
The orange LED extinguishes when sufficient light reserve is present.
Fine tuning
Subsequent to the face-parallel installation and/orto the alignment using the adjustment laser,
fine tuning is carried out by means of the adjusting screws on the supplied fastening brackets,
provided that the orange LED is lit.
To swivel along the longitudinal axis, the respective adjusting screw on one of the fastening
brackets is turned whilst both screws on the other fastening bracket are loose. To swivel the
lateral axis, both screws of one fastening bracket are turned at the same time whilst both
screws on the other fastening bracket are loose.
Subsequently, the green or yellow LED on the receiver should light up, and the orange
LED must have extinguished.

Test rod:
Using the test rod, the light barrier is to be interrupted on the transmitting side from start to finish in such
a way that the light field is only covered by this part. The green LED must not light up from start to finish. The
diameter of the test rod must correspond to the obstacle size specified on the nameplate of the receiving side.
