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.
1
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.
In front of the Transmitter.
In front of the Receiver.
At the middle point between Transmitter and Receiver.

Attach the "Beam Blocking Tool" to the lower mirror
on both the transmitter and receiver.
Adjust the upper mirror.

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.

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.
Checking From The
Monitor Jack
After adjusting with the LED
indicators, check the voltage at
the monitor jack output using
your meter. This will insure
proper beam alignment.
Con
fi
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
(-).
Check the alignment levels of the upper and lower
beams separate from one another and ensure that
both reach excellent as stated in the chart.

Set the volt-meter range
to 5~10 VDC.
