6.3 Alignment of Unit (Figure 8, 9) Using Tilt Mount
Using the Telescope performs full alignment.
Alignment procedure should be performed in two stages: Crude alignment then
fine adjustment.
The Telescope includes a Periscope that consists of a prism and an ocular
located vertical to the Telescope assembly. This allows the user to observe the
opposite unit perpendicular to the alignment when access from the rear of the
unit is impossible. For installations where rear access is possible, the Periscope
is not necessary. In this case it can be removed by releasing the Periscope
Fastening Screw.
Important Notes
a. Prior to Telescope Installation, verify that the Telescope and its Sight
Mounting are free from any dirt to ensure proper alignment according to
factory calibration.
b. Do not attempt to change any factory calibration at the Telescope or its
mounting. This may prevent optimal alignment.
Alignment procedure (refer to Figure 9):
1. Make sure that the Detector and the Flash Source are installed properly.
Installation instructions are described in section 5 of this document.
2. Install the Telescope Assembly (9) on the Telescope Site Mounting of the
Source according to the drawing. Fasten the Telescope with Fastening Screw
(10).
3. Crude Alignment - Source
a. Use 1/4” Allen screwdriver for all alignment screws.
b. Loosen screws 5, 6.
c. Approximately aim the Source horizontally toward the Detector.
d. Tighten screw 5
e. Loosen screws 3, 4
f. Approximately aim the Source vertically toward the Detector
g. Tighten screw 3
4. Repeat 3 for the Detector
5. Fine Alignment- Source
a. Aim the source at the Detector within horizontal axis using screws 7.
Aim the cross to the upper level of the telescope site of the detector.
b. Tighten screw 6.
c. Aim within the vertical axis using screw 8.
d. Tighten screw 4
e. Make sure the telescope cross is pointing at the top of the telescope
site of the detector.
6. Repeat 5 for the Detector fine alignment.
