6. Operating Instructions
6.1 SafEye Operation
Once the system is positioned, it will monitor for possible specified gases,
automatically sending signals to a standard control panel or a PC.
This chapter describes the alignment, calibration and operation.
Important!
Accurate Alignment is essential for proper operation of the SafEye system.
6.2 Alignment of Unit (Figures 15 through 16) Using Swivel Mount
(See 6.3 for Alignment using Tilt mounts)
This section applies to open-path installation only. For duct mount applications
the alignment is performed according to section 5.5.5. Therefore, skip steps 1
through 10 when duct mount installation is performed.
The Telescope is used for 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 difficult/impossible. In installations where rear access is possible, the
Periscope is not necessary. In this case it can be removed by releasing the
Periscope Fastening Screw (item 5 at figure 16).
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 of the
Telescope or its mounting. This may prevent optimal alignment.
1. Make sure that the Detector and the Light Source are installed properly.
Installation instructions are described in section 5 of this document.
2. Refer to Figure 15. Slightly release four Protective Sight Covers’ screws
(Figure 15, item 6) from the Detector and the Light Source. Do not remove the
screws from the Covers. Remove the Protective Sight Covers (Figure 15, item
7) from the Detector/Light Source Assembly. Store the Cover in a clean place
for reinstallation after alignment is completed.
3. Refer to Figure 17. Install the Telescope Assembly (1) on the Telescope Sight
Mounting (2) of the Detector according to the drawing. Fasten the Telescope
with Fastening Screw (3).
