Technical line drawing of a rectangular electronic device with mounting holes and a connector (no text or symbols)

Functions and features

In conjunction with a prismatic reflector or reflective tape the retro-reflective sensor detects objects and materials without contact and indicates their presence by a switched signal.

Range: see type label (values referred to prismatic reflector with ∅ 80mm).

Controls and indicators

potentiometer 1 sensitivity potentiometer 2 duration of time delay sens time on off time a b S1: output function S 2: time function S 3: type of time delay switch position a: switching delay when object moves out of the beam (uninterrupted light beam) switch position b: switching delay when object moves into the beam (interrupted light beam)

Electrical connection

Disconnect power before connecting the sensor.

Connection strictly to the indications on the type label.

Note: insert a miniature fuse according to the technical data sheet, if specified.

Recommendation: check the unit for reliable function after a short circuit

Installation

LEDs red, yellow, green LED red

Fix the prismatic reflector / reflective tape in desired position. Align the photocell and fix it by means of a mounting device.

Following electrical connection the photocell can be set exactly by means of the LED display:

• The red LEDs light if setting is exact.
• They flash if setting is inexact.
  • Maximum range only with precise alignment.

Setting

Set the sensitivity, the output function, the time function as well as the type and duration of the time delay.

Switch 3 = a:

The signal “no object present” is transferred to the switching output after a delay.

• In the case of S1 = the output switches OFF after the falling edge + t.
• In the case of S1 = the output switches ON after the falling edge + t.

A pulse during the time t triggers the timer again.

object 1 0 S1 = - 1 0 S1 = - 1 0 -t- t- t' -t- t'-t-

Switch 3 = b:

The signal “object present” is transferred to the switching output after a delay.

• In the case of S1 = the output switches ON after the rising edge + t.
• In the case of S1 = the output switches OFF after the rising edge + t.

A pulse during the time t triggers the timer again.

Objekt S1 = 1 0 -T- -t- t' -S1 = 1 0 -T- -t- -t- t' -t-

Operation

Check the safe functioning of the photocell.

Display by LEDs and function-check output.

• Green LED is lit = supply voltage o.k.
• Red LEDs are lit = light reception (no object between photocell and reflector).
• Red LEDs flashing = reception deteriorating (e.g. by soiling of the lenses or maladjustment).
• Yellow LED is lit = output switched.

The function check output indicates a wrong object detection (soiling of the lenses, maladjustment) by means of a 5 Hz signal. When the object is again clearly detected, the output provides again a continuous signal.

fc-out 1 0 100ms fault UB 1 0

Maintenance: Keep the lens of the sensor free from soiling.
