5-3.Optical Alignment - Optex AX-250PLUS Installation Manual

5-3. OPTICAL ALIGNMENT
When using two or more units on wire, the maximum length is obtainted by dividing the maximum wire length listed below of units used.
Power wires should not exceed the following lengths.
Beam Frequencies
Selection
STEP1
Select the beam frequencies
switch.
Horizontal & Vertical
Adjustment
STEP2
Looking into view fi nder of the
Transmitter, and adjustment the
lens holizontally and vertically,
so that the Receiver can be
seen in the center of the sight.
STEP3
Looking into the view fi nder
of Receiver and make fi ne
adjustments horizontaly and
vertically.
LED INDICATION
Checking From The
Monitor Jack
STEP4
After adjusting with the LED
indicators, check the voltage at
the monitor jack output using
your meter. This will insure
proper beam alignment.
Confi rmation
Check that the operation indicator ("ALARM CONDITION" LED) light is OFF.

2 If the indicator light is ON even thought the beams are not blocked re-adjust the optical alignment and check wiring. (See sec. 5-3)
3 After alignment is achiened and the units work properly, conduct a walk test at a minimum of three points.
Action
In front of the Transmitter.
In front of the Receiver.
At the middle point between Transmitter and Receiver.
1 HORIZONTAL ADJUSTMENT
Turn mirror base by hand to obtain the highest
alignment level.
Make fi ne adjustment by turning "Fine Adjustment
Screw".
ADJUST THE UPPER MIRROR
1
Attach the "Beam Blocking Tool" to the lower mirror
on both the transmitter and receiver.
Adjust the upper mirror.
"Excel" reading on the LED indicator is suffi cient.
The alignment level indicators have 5 LEDs, each LED represents the level of alignment, ranging from poor to
excellent (See illus.)
Each LED will indicate 3 steps of alignemt, slow fl icker = okay, fast fi cker = better, continuously on = best
Providing 15 graduated stages.
ALARM CONDITION LED
ON: ALARM CONDITION
OFF: RECEIVING BEAM OR POWER IS NOT SUPPLIED.

Confi rm the beam alignment level by setting your volt-meter to the 5~10V DC range, cover either the upper
or lower beam and compare the voltage reading with the following chart.
Connect the volt-meter probes
(+) to monitor jack (+), and volt-
meter probes (-) to monitor jack
(-).

○ Match the frequency settings. (See Sec. 7-1 SELECTABLE BEAM
FREQUENCIES.)
○ When stacking beams or installing more than one set in the same area.
2 VERTICAL ADJUSTMENT
Turn vertical adjustment asrew to get highest level
ADJUST THE LOWER MIRROR
2
After the fi nal adjustments are made on the upper
mirrors, carefully (do not move mirror) remove the
shieldinh tools from the lower mirrors and place them on
the upper mirrors of both the transmitter and receiver.
Make the horizontal and vertical adjustments to the
lower mirrors.
"Excel" reading on the indicator is suffi cient.
Check the alignment levels of the upper and lower
5~10V DC
beams separate from one another and ensure that
RANGE
both reach excellent as stated in the chart.
ALIGNMENT
Set the volt-meter range
to 5~10 VDC.
Optical Alignment for Indoor Use
Obtain maximum voltage from the monitor jack, at least more than 3.4V
