1. Installation Precautions

Caution• The sensing head should be kept as close as possible to the target object.
• When installing this sensor, no obstacles should be placed between the sensing head
and target object.
• This sensor has a temperature operating range of -20 to 85(for sensing head) and
0 to 65(for electronics module).
• This sensor has a humidity operating range of 10 to 95 %RH (non-condensing).
• The sensing head lens should be protected from powder, dust, etc.
• Use an air purge collar (ATAL, sold separately) when this sensor is mounted in a place
where fumes, dust, gases or contaminants are present.
(Airflow: 2 to 10 liters/minute)• Install this sensor away from electrical noise, motors or generators.

2. Wiring Precautions

Warning• Never connect the power supply to the analog output. The output circuit will break.

3. Measurement and Maintenance Precautions

Caution• When using the air purge collar, make sure to use oil-free, clean compressed air.
• Clean the lens surface with a soft, damp cloth or tissue paper moistened with water orwater based glass cleaner. (Never use cleaning compounds which contain solvents.)• As the display section of the electronics module is vulnerable, do not strike or scratch itwith a hard object or put pressure on it.
• The Average time is set to the minimum value as a factory default, so fluctuation may
occur in indication and output action depending conditions.
In this case, set the Average time to a suitable value.

Warning• Turn the power supply to any connected instruments (indicators, controllers,etc.) OFF before wiring.
Working on or touching the terminal with the power switched ON may result insevere injury or death due to electric shock.
• Never connect the power supply to the analog output. Output circuit will break.

CautionWhen using this sensor in a place where electrical noise is present, connect theshield (using a shielded wire) to the ground terminal of any connected
instruments (indicators, controllers, etc.).
If they have no ground terminal, connect the shield to the ground terminal of thecontrol panel.

Emissivity
Emissivity is a ratio between the amount of energy radiated from a black body with acertain temperature (or an object with perfect radiation), and the amount of energy
radiated from an object with the same temperature.
Accordingly, emissivity value is high for an object which easily radiates infrared,
and low for an object which radiates infrared with some difficulty.
For objects such as organic substances and ceramics, etc. (except metals), theiremissivity value is high, which ensures a highly accurate measurement.
On the other hand, emissivity is low in lustrous metals and lustrous objects, resulting
in measurement being affected by reflection. By attaching a black body tape to theobject surface, high measurement accuracy can be obtained.
For tables of emissivity, refer to Appendix A (Emissivity Table: Metals) and Appendix
B (Emissivity Table: Non-Metals) at the end of this manual. (Pages 37 to 39)

7. Measurement
Important• If ambient temperature is rapidly changing, leave the sensor for more than 20 minutes
as it is, then measure the temperature.
• Do not measure temperature near a large magnetic field (example: Arc welding
machine, induction heater, etc.). Measurement errors will occur due to electromagnetic
disturbance.
• Indication may not be stable due to the mounting environment.
The sensor will detect any light reflected from the target object from surrounding lightsources.
After installation of the target object and wiring are completed, start operation, following
the procedures below.
(1) Turn the power ON.
After the power is turned ON, the LCD display indicatesfor several seconds.
After that, the temperature of the target object will be indicated on the LCD display.

If problems arise, please check the following suggestions.
ProblemPossible Cause and Solution
No output• No power.
Ensure that the power is being supplied properly.
• Wiring may be incorrect.
Check the wiring.
Abnormal temperature• Wiring may be incorrect.
Check the wiring.
• Sensor may be disconnected.
Check if the sensor is conducting properly.
• Lens may be dirty.
Remove any dirt on the lens.
Always keep the lens clean. Foreign particles on the lensaffect measurement accuracy.
• Set values such as emissivity, average time, peak holdtime, etc. may be set to incorrect values.
