2. Target Objects• Non-problematic objects
Food, paper, plastics, cloth, leather, cigarettes, medicine, chemicals, rubber, asphalt, coal, etc.
• Difficult objects
Plated lustrous metals, uncoated or unpainted metals, etc.
• Slightly problematic objects
Low lustrous metals, thin transparent plastics, etc.
If measurement is difficult, black body tape can be used to raise emissivity.

3. Installation
Ensure the installation location corresponds to the following conditions.
• The sensing head should be kept as close as possible to the object.
• The ambient temperature of the sensing head should not exceed 120 (248 ).
The ambient temperature of the electronics should not exceed 80 (176 ).
• The sensor lens should be protected from being covered with powder, dust, etc.
• Use an air purge collar (ASAP, sold separately) when using this sensor in a place
where a lot of fumes, dust or moisture is present. (Airflow: 2 to 10 liter/sec)• Install this sensor away from electrical noise, motors or generators.
For the mounting method of the mounting bracket (TFB, sold separately), see pages 3, 4.
For the mounting method of the Air purge collar (ASAP, sold separately), see pages 4, 5.

Mounting procedure are shown below.
(1) Fix the mounting bracket at the desired site using a screw (M3 size – not included).
(2) Remove the hexagonal nut (SW 14) from the sensing head, and pass the sensing headthrough the mounting bracket. Secure it using the hexagonal nut.

(Fig. 3.2.2-2)
3.2.3 Mounting When the Air Purge Collar (ASAP, sold separately) is Used
The air purge collar is used to suppress rises in temperature of the sensing head,
and to keep fumes, dust, gases and other contaminants away from the lens.
The mounting bracket (TFB, sold separately) is also necessary.
• Airflow: 2 to 10 liters/minute• Use clean, oil-free compressed air.

(3) Pass the air purge collar through the mounting bracket, and secure it using the hexagonal nut.

(Fig. 3.2.3-6)(4) Attach the tube and air pump to the air purge collar.
Refer to the tube size and air pump specifications recommended below.
Recommended tube size: Inside diameter: 4 mm; Outside diameter: 6 mm
Recommended air pump: Air pump should fit tube size and deliver a discharge air flow rate
corresponding to the air purge collar (2 to 10 liters/minute).

4. Wiring
Warning
Turn OFF the power supply to the indicator/controller before wiring.
Working on or touching the terminal with the power switched ON may result in severe injury or
death due to electrical shock.

CautionWhen using the sensor in an environment where electrical noise is present, use a shielded
wire, and connect it to the ground terminal of the indicator/controller.
If the indicator/controller does not have a ground terminal, connect to the ground terminal ofthe control panel.
4.1 Wiring Example

For details, refer to the Instruction Manual for the ACS-13A- /A.
• If a fixed emissivity of 0.950 is used, any indicator/controller can be used.

5. Measurement
Attention• If ambient temperature is rapidly changing, leave the sensor for more than 20 minutes as it is, thenmeasure the temperature.
• Do not measure temperature near a large magnetic field (example: Arc welding machine, induction
heater, etc.). Measurement errors will be caused due to electromagnetic disturbance.
After completing installation for the target object and wiring, start operation following the procedures below.
(1) Turn the power to the sensor ON (RDP-24).
(2) Turn ON the power to the indicator/controller (ACS-13A- /A).
(3) Measure the temperature.
