The selectable beam frequencies can be used to avoid unwanted crosstalk that can occur when using multiple photo-
beams for long distance or beam stacking applications.
・
To select between 4 separate beam frequencies, use the switch provided.
・
Make sure the receiver and transmitter that are facing each other are set to the same channel.
・
More than double stacked application is not possible.

5. ALIGNMENT
5-1 OPTICAL ALIGNMENT
The optical alignment is an important adjustment to increase reliability. In accordance with the procedure indicated in the items 1. and 2. in this
chapter, make sure to align the monitor jack that monitor output nothing to attain the maximum level.
1. Rough alignment by viewfi nder
・
While looking through the viewfi nder, turn the dial to make alignment in such a way that the other detector is at the center of the sights.
< Horizontal alignment > < Vertical alignment >
Turn the horizontal alignment
dial by fi ngers to make align-
ment
Turn the vertical alignment dial
with a screwdriver to make
alignment
The beam is not
properly aiming at the
center of viewfi nder.

Fine adjustment with monitor jack
・
After checking the receiving level of optical axis by using
the alarm indicator, make sure to make fi ne alignment for
both transmitter and receiver with voltmeter until it reaches
maximum monitor output over “Good” level.
Set the voltmeter range to 5
to 10VDC and connect the
voltmeter probes
⊕
and
⊖
to
⊕
and
⊖
of the monitor
jack respectively.
When making the adjustment by the monitor jack, be careful not to intercept the optical unit with your hand, the tester pin cord, etc.
The horizontal / Vertical alignment.
The alignment
can be completed.

[AX-70/130/200TN]
Always switch the frequencies TWO channels apart when stacking units on top of one another (See following example) .
The upper unit is set on channel 1 while the lower is on channel 3.channels 2 and 4 could have also been used.
