3 Functions and features

The diffuse reflection sensor detects objects and materials without contact and indicates their presence by a switching signal.

Range 20 ... 200 mm (on white paper 200 x 200 mm, 90 % remission)

4 Installation

1: LED

2: programming buttons

▶ Align the diffuse reflection sensor to the object to be detected.
▶ Secure it to a bracket.

Note:

The objects to be detected are to move transversally to the lens of the sensor.

▶ In case of other directions of movement it should be tested before whether safe switching is guaranteed.

5 Electrical connection

The unit must be connected by a qualified electrician.

▶ The national and international regulations for the installation of electrical equipment must be adhered to.
▶ Voltage supply according to EN 50178.

▶ Disconnect power.
▶ Connect the unit as follows:

DC PNP

pin 1 = L+ ( 10...36 V DC )

pin 3 = L-

pin 4 = load (200 mA)

(pin 2 = not connected)

DC NPN

pin 1 = L + ( 10...36 V DC )

pin 3 = L-

pin 4 = load (200 mA)

(pin 2 = not connected)

6 Settings

6.1 The sensor is to switch when the object is detected

1	▶ Position the object
	▶ Press [OUT on] for 2 s. ▷ The sensitivity is set to the object. ▷ The LED flashes.
2	▶ Remove the object
	▶ Press [OUT off]. ▷ The sensitivity is set without object. ▷ The LED goes out. The programming is finished.

6.2 The sensor is not to switch when the object is detected

▶ Position the object (see figure 1) and press [OUT off] for 2 s.
▶ Remove the object (see figure 2) and press [OUT on].

The setting can also be carried out first without object and then with object.

6.3 Setting of the maximum sensitivity

▶ Align the sensor so that no light is reflected.

The sensor is to switch when the object is detected

▶ First press [OUT on], then [OUT off].

The sensor is to switch when the object is not detected

▶ First press [OUT off], then [OUT on].

6.4 Programming unsuccessful

▷ The LED flashes quickly, 8 Hz.
• Measured value difference too small
• Max. programming time (15 min.) exceeded.

6.5 Electronic lock

Lock or unlock the buttons

▶ Press [OUT on] and [OUT off] simultaneously for 10 s.

▷ Acknowledgement is indicated by a change of the LED status.

7 Operation

▶ Check whether the unit operates correctly.

▷ The LED lights when the switching output is switched.

8 Maintenance, repair and disposal

▶ Keep the front pane of the sensor free from soiling.
▶ For cleaning do not use any solvents or cleaning agents which could damage the plastic material.
▶ Do not try to open the module enclosure. There are no user - serviceable components inside.
