12.3 Electronic Alignment
After completing Optical Alignment it is necessary to optimise the alignment by using the
built
in electronic system
.
It is possible to optimise the received signal level using a test meter or visible indications
proportional to the received signal. These indications are available on the
receiver of IR Optical
Module 100 and IR Optical Module 160 models.
Alignment must be performed on each optical module. Start aligning the upper RX and TX
optical modules.
1. Using a
test meter
:
I.
Set dip switch n°6 to ON (Upper Beam Alignment)
II.
Insert the probes of the test meter in the “Alignment Check Terminals” located on
the optical module, and set the voltage range to 10VDC scale
III.
Using a screwdriver adjust the vertical and horizontal adjustment screws on the
module to get a voltage higher than 3V
IV.
Set dip switch n°6 to OFF (Lower Beam Alignment)
V.
Perform lower beam alignment according to steps II. and III. above
2. Using the
LED
:
I.
Set dip switch n°6 to ON (Upper Beam Alignment)
II.
Adjust the vertical and horizontal adjustment screws with a screwdriver, while
checking the status of the
“level” LED on the receiver
III.
“Level” LED displays the amount of beam received. As more beam energy is
received, the illumination times shortens. When the “level” LED turns off, the
alignment is complete
IV.
Set dip switch n°6 to OFF (Lower Beam Alignment)
V.
Perform lower beam alignment according to steps II. and III. Above
