Putting Into Operation; Important - Abus LS2030 Mode D'emploi

5. Screw the mounting plate with 3 screws M4x10 tightly to the base-plates of
the transmitter and receiver.
6. Fix the mounting plates to the mounting brackets.
7. Repeat steps 3–7 of "Wall mounting".

Putting into operation

Before aligning the photoelctric beam, connect the power supply.
You can also connect up the alarm and tamper lines after alignment.
7.1 Rough alignment with laser and LED

Important:

Never look directly into the laser beam! The laser used has a power of
<= 5 mW at a wavelength of 650 nm and belongs to Class 3a (classification
according to DIN VDI 0837).
1. Switch on the laser switch of the transmitter.
2. Align the transmitter horizontally and vertically so that the laser beam
points to the centre of the receiver. Alignment is optimal when both LEDs
of the receiver stop lighting.
3. To check: repeat steps 1 and 2 with the laser on the receiver.
The LED on the receiver gives you a first indication of the strength of the received
signal.
Alarm LED (red) and signal LED (yellow)
Both LEDs OFF
One LED ON
Both LEDs ON
7.2 Fine adjustment by voltage measurement
1. When the transmitter and the receiver are firmly mounted at the installation
location, you can make the fine adjustment of the photoelctric beam by
measuring the voltage level.
2. Switch your measuring device to the setting "DC" and select the lowest
voltage range (0-10 V DC).
3. Measure the voltage on the receiver and compare the value with the table
below.
