4. Detector Crude Alignment:
Refer to Figure 16 for all the following instructions.
a. Use 3/16” Allen screwdriver to loosen up the 3 socket set screws (7).
b. Tilt the Light Source in the general direction of the Detector.
c. Rotate the Periscope (4) until its ocular is positioned in front of your
aiming eye for most convenient observation.
d. Observe through the Periscope (4) and locate the Detector in the
center of view of source unit.
e. Tighten three socket set screws (7) of the Detector’s Swivel Mount.
5. Release the Fastening Screw (3) and remove the Telescope from the
Detector.
6. Light Source Crude Alignment
Repeat Steps 3 through 4 for the Light Source.
7. Light Source Fine Adjustment:
a. Release the Adjustment Screw Securing Nuts (10) from all Adjustment
Screws (8,9) to enable fine alignment.
b. Watch through the Periscope (4). The cross midpoint inside the
Telescope Lens should be aimed to the opposite unit (Light Source)
such that it is observed in the Periscope.
c. Rotate the Vertical Adjustment Screws (8) and the Horizontal
Adjustment Screws (9). This should be performed until the cross
midpoint is combined with the center of the top of the Light Source
Telescope Sight Mounting (Figure 16, item 2).
d. Carefully secure the four Adjustment Screw Securing Nuts (10).
Release the Fastening Screw (3) and remove the Telescope (1) from
the unit.
8. Detector Fine Adjustment
Repeat Steps 3 and 7 for the Detector.
9. Repeat steps 3,7 and 8 if additional Adjustment is required.
10. Upon alignment completion perform the following:
a. Reinstall Protective Sight Covers on the Detector and the Light
Source by screwing four Sight Cover screws (Figure 16, item 6).
b. Return the Telescope to its Original case.
11. Power on the system according to section 6.4
12. Perform zero calibration according to section 6.6
13. Perform Signal Intensity Check (SIC) according to section 7.2.2
14. Perform Functional Check (FC) according to section 6.7
