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.

Upper Mirror Fine
Adjustment
Connect the volt-meter to
monitor jack input on Receiver's
(+) and (-), then
fi
ne tune optical
alignment.
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.

Vertical Adjustment
STEP3
Lower Mirror Fine
Adjustment
Check the voltage using the
monitor jack and make any
fi
ne
adjustments the lower mirror.
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.
2
Horizontal Adjustment
Adjust the vertical alignment
screw to obtain the maximum
voltage from the monitor jack.
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.

Final checking after
removing the “Beam
Blocking Tool” from
the mirror.
STEP4
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.
1
Check that the operation indicator (“ALARM CONDITION” LED) light is OFF.
2
If the indicator light is ON even though the beams are not blocked, re-adjust the optical alignment and check
wiring. (See sec. 4-3)
3
After alignment is achiened and the units work properly, conduct a walk test at a minimum of three points.
In front of the Transmitter.
In front of the Receiver.
At the middle point between Transmitter and Receiver.
