Frequently Asked Questions - OA5114 IFM

How to install the OA5114 detector?

Before any installation, disconnect the power supply. Fix the receiver (OAE...) using a mounting bracket. Point the transmitter (OAS...) towards the receiver and fix it in the same way. Follow the wiring diagram on the label.

How to correctly align the transmitter and receiver?

Point the transmitter towards the receiver. The red LEDs of the receiver indicate alignment quality: steadily lit = precise alignment; flashing = poor alignment. Adjust until the LEDs are steady.

What do the different LEDs on the device mean?

The green LEDs of the receiver indicate that the supply voltage is OK. The red LEDs lit = light reception (no object between transmitter and receiver). If they flash, this signals deteriorated reception (e.g., dirty lenses or misadjustment). The yellow LED lights up when the output is switched.

How to set the timer of the detector?

Use the selector 3 to choose mode A (delay on 'no object' signal) or b (delay on 'object present' signal). Set the timer duration t. Depending on the position of selector S1, the output switches on or off after the appropriate edge.

How to perform a function test?

Activate the test input (test to L-) on DC devices. The light emission is deactivated. If no object is between the transmitter and receiver, the red LEDs on the receiver must turn off and the output state must change.

What to do if the red LEDs flash?

Flashing red LEDs indicate poor reception due to dirty lenses or misadjustment. Clean the lenses with a soft cloth and check the alignment of the transmitter and receiver.

How to clean the detector lenses?

Disconnect the power supply. Use a soft, non-abrasive cloth to gently clean the lenses. Avoid any harsh chemicals.

What is the required power supply for the OA5114?

The device operates on direct current (DC). The typical supply voltage is 10-30 V DC. Check the label for the exact value.

How to check proper operation after installation?

Restore power to the installation. Check that the green LEDs are lit (power OK). Place an object between the transmitter and receiver: the red LEDs must turn off and the yellow LED must turn on if the output is switched. Use the diagnostic output to detect any degradation.

What to do in case of a short circuit?

After a short circuit, check the proper operation of the device. Replace the miniature fuse if necessary. If the problem persists, contact technical support.

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

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

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.

• 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.

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.

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