Through-beam sensor OA

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

Functions and features

The through-beam sensor detects objects and materials without contact and indicates their presence by a switched signal.

Range: see type label.

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

LED green LEDs red, yellow, green LED red

Fix the receiver (OAE...) in position.

Align the transmitter (OAS) towards the receiver and tighten in the same way.

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

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

Test input of the transmitter (only for DC units)

By activating the test input (test at L-) the transmitter is deactivated. When no object is in the light beam between transmitter and receiver the LEDs indicating the reception of light must go off and the switching state of the output must change.

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.

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

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

Operation

Check the safe functioning of the through-beam sensor.

Display by LEDs and function check output.

• Green LEDs are lit = supply voltage o.k.
• Red LEDs are lit (receiver) = light reception (no object between transmitter and receiver).
• 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.
