3. Operating Guidelines
Use protective eyewear whenever there is a risk of being exposed to the
output beam of the 4000-LIR or 4000-LV.
Use eyewear specifically designed
to block laser radiation of the frequency used by the sensor.
Do not point the sensor at any person, particularly a person’s eyes or face.
Laser radiation can damage the eyes without sensation or warning.
Do not attempt to disassemble the sensor.
Improper disassembly will destroy
the optical alignment of the sensor and necessitate factory repairs.
Do not operate the sensor in areas where the sensor case is exposed to direct
sunlight for more than a minute or where the air temperature is more than
45
°
C (113
°
F).
If the sensor is to be used in temperatures below 0
°
C (32
°
F),
apply power to the heater power supply lines. This will allow the sensor to
maintain a constant internal temperature, ensuring optimum operation.
Do not point the sensor at the sun or other intense heat sources.
The sensor
will operate when pointed at sunlit areas, although sensitivity is reduced. The
optional optical filter is recommended for use on sunlit target areas.
Avoid excessive vibration and shocks
. The sensor contains securely mounted
but precisely aligned optical components. These components are isolated from
the case with shock mounting, which protects them from all but severe shocks to
the case.
Do not scratch the front face of the sensor, particularly in the central area.
Keep the front face clean with a damp cotton cloth. The face is acrylic with an
anti-abrasion coating. Avoid the use of cleaning solvents other than alcohol.
