Optical Alignment - Optex Smart Line Series Installation Instructions Manual

4-2 OPTICAL ALIGNMENT

Optical alignment is an important procedure to increase reliability.
Be sure to take alignment step 1 through 5 described below to
attain the maximum level of the output through the monitor jack.

Perform rough alignment of the horizontal angle.
Beam blocking plate
Note>>
• Mount a beam blocking plate to the lower
unit and then start optical alignment from
the upper unit.
• Beam blocking plate is attached on the
back of the cover.
• Return the beam blocking plate to the
cover after use.

- Clockwise: Upward
- Counterclockwise: Downward
Warning
• Do not look at strong light sources such as sunlight
through the viewfinder.
Caution
• Do not touch the lens during optical adjustment.

After the alignment using the viewfinder, make adjustment
with the voltmeter for more accurate optical alignment.
Set the voltmeter range to 5 to 10 VDC.
After checking the receiving level of optical axis by using
the Level indicator LED, make sure to make fine
alignment for both transmitter and receiver with voltmeter
to achieve a monitor output level of "Excellent".

Adjust the horizontal and vertical angles while checking
the light receiving status by Alarm indicator LED on the
pairing receiver.

Caution
• The Alarm indicator LED is a supporting tool for
easy alignment. Be sure to perform fine alignment
to ensure the maximum output level through the
monitor jack.
• The Level indicator LED should only be used for
rough alignment, for fine alignment always use the
monitor jack output level.
