.
For synchronized applications or stacked
sets of transmitters and receivers, install
interruption sheets on all optical
modules except the pair to be aligned.
10. Do one of the fine alignments. Refer to Table 9 on
page 13 to determine which procedure to use.
For the following procedures, make sure
that all optical modules are covered with
interruption sheets, except the pair to be
aligned.
Remove the interruption sheets and close
the covers when the alignment is complete.
4.2.3 Voltmeter Alignment
1. Insert voltmeter leads into the alignment check
terminals on the receiver panel. Refer to Figure 3
on page 3
2. Set the voltmeter scale to 10.0 VDC.
3. Use a screwdriver to adjust horizontal and vertical
adjustment screws on the transmitter and the
receiver. Refer to Figure 21 on page 14.
4. Check the voltage reading and continue to adjust
the adjustment screws as necessary. In an ideal
environment, the voltmeter value should be
3.0 VDC or higher. (The maximum voltage is 3.75
VDC.)
5. When the best voltage is achieved, the optical
modules are aligned.
6. Repeat the procedure for the other optical module
pair.
4.2.4 Level LED Alignment
1. Look at the Level Meter on the receiver. Refer to
Figure 23. When you begin this procedure the
LEDs are off.
2. Use a screwdriver to adjust the optical modules.
Adjust the horizontal and vertical adjustment
screws as necessary. Refer to Figure 21.
3. As more beam energy is received, each LED turns
on, flashes quickly, flashes slowly, and then turns
off.
4. Continue fine tuning until the LEDs turn off.
•
If outdoors, the alignment is complete when all
LEDs are off.
•
If indoors, the alignment is complete when the
lower two LEDs are off.
5. Repeat the procedure for the other optical module
pair.

1. Set DIP Switch 6 on the receiver to ON. Refer to
Figure 23.
2. Use a screwdriver to adjust the optical modules.
Adjust the horizontal and vertical adjustment
screws as necessary. Refer to Figure 21.
3. As more beam energy is received, the sound pitch
changes from low to high and from a continuous
tone to a two beat sound.
4. Continue fine tuning until the buzzer is a two-beat
sound.
5. After the beams are aligned, set DIP Switch 6 to
OFF.
6. Repeat the procedure for the other optical module
pair.
