4-3.Optical Alignment - Optex AX-250PLUS Installation Manual

4-3. OPTICAL ALIGNMENT
When using two or more units on wire, the maximum length is obtained by dividing the maximum wire length listed below of units used.
Power wires should not exceed the following lengths.
Rough alignment by
view fi nder
STEP1
Looking through the view fi nder,
locate the other detector in the
center of the sights by adjusting
vertically and horizontally.
Upper Mirror Fine
Adjustment
STEP2
Connect the volt-meter to
monitor jack input on Receiver's
(+) and (-), then fi ne tune optical
alignment.
Lower Mirror Fine
Adjustment
STEP3
Check the voltage using the
monitor jack and make any fi ne
adjustments the lower mirror.
STEP4
Final checking after
removing the "Beam
Blocking Tool" from
the mirror.
Check that the operation indicator ("ALARM CONDITION" LED) light is OFF.
1
Confi rmation
If the indicator light is ON even though the beams are not blocked, re-adjust the optical alignment and check
2
of
wiring. (See sec. 4-3)
After alignment is achiened and the units work properly, conduct a walk test at a minimum of three points.
3
Action
Adjust the optical alignment for
Transmitter and Receiver one at a
time.
Put the attached "Beam Blocking
Tool" on the lower mirror of both the
transmitter and the Receiver.
Secondly, adjust the lower morrors.
After the fi nal adjustment are made on the upper
mirrors carefully without moving morror remove
"Beam Blocking Tool" from the lower mirrors
and place them on the upper mirrors of both the
Transmitter and Receiver.
Be carefull when removing the "Beam Blocking
Tool" from the mirror-Don't move mirrors.
In front of the Transmitter.
In front of the Receiver.
At the middle point between Transmitter and Receiver.
Looking through the view fi nder, locate the other detector in the
center of the sights by adjusting vertically and horizontally.
Vertical Adjustment
1
Adjust the vertical alignment
screw to obtain the maximum
voltage from the monitor jack.
After the vertical and horizontal adjustment are made, recheck
the voltage from monitor jack is over 5.0V. If not, adjust the
optical alignment again.

obtain maximum voltage from the monitor jack, at least more
than 2.2V
Carefully remove the "Beam Blocking Tool" from the upper mirror of both
Transmitter and Receiver also check the voltage from the monitor jack again.
Then check again that the voltage from monitor jack is more than about 5.0V.
if not, adjust the optical alignment again.
