If an additional sensor set is mounted, interference may occur. In this
case, for sensors with AC supply, two sensor sets can be connected
in synchronization mode to eliminate crosstalk. See fig. G as well as
"Sync Jumper" in "Jumper settings and connections".
4. In case the back cable entrance is used, the PG cable gland must be
replaced by the blind cap. See fig. F and J.
5. Fix the sensor as shown in fig. E. To ease the mounting of the wires in
the terminal block, the sensor block can be separated from the base
using a screwdriver. See fig. K.
6. Connect the sensor to the door controller as shown in fig. C, in case a
single sensor is used.
7. Align the lenses while following the guideline below:
a. Alignment using the laser alignment tool "APD140-LA01":
Switch on the laser and place it in the emitter's lens holder. Align the
laser towards the receiver lens.
Place the laser in the receiver's lens holder and align it towards the
emitter lens.
Alignment within ±0,5° is sufficient.
Distance between sensors
b. Alignment using the alignment output:
Move the alignment jumper to position 2 (see "Jumper settings
and connections") and place the alignment test cable "APD140-
TC01" in "Align put". Connect also the test cable to a voltmeter (see
"Jumper settings and connections").
Align the emitter and receiver lenses towards each other and contin-
ue doing so until the maximum voltage output is reached.
After alignment, move the alignment jumper back to position 1 (see
fig I).
c. Alignment using the flashing yellow LED:
Move the alignment jumper to position 2 (see "Jumper settings and
connections").
The yellow LED can be used for aligning the sensors at distances up
to 6 m.
Adjust the emitter and receiver lenses until the yellow LED flashes
until it flashes with the highest speed or lights up steadily. If the
green LED is lit, the excess gain is higher than 4.
After alignment, move the alignment jumper back to position 1 (see
"Jumper settings and connections").
Testing
The sensors must be tested to verify that they are working correctly after
installation.
1. Make sure that the sensors are installed according to instructions in
this manual.
