Frequently Asked Questions - OL5040 IFM

How to wire the OL5040 sensor?

Wiring depends on the version. Refer to the wiring diagram provided in the manual, page 14. DC PNP, DC NPN or AC/DC relay versions have different diagrams.

What is the sensor range?

The range (r) is indicated on the device label. It varies according to the model and installation conditions.

How to program the switching threshold for moving objects?

Press the button until the red LED flashes (programming mode). Place the object in the beam, press once. Remove the object, press once. The green LED lights up to confirm.

What to do if the red LED flashes after programming?

This indicates that the threshold adjustment failed (object/background signals too close). The sensor returns to operating mode without changing the threshold. Check alignment and lens cleanliness.

How to invert the output logic (light-on ↔ dark-on)?

Hold the button pressed for 10 seconds until all LEDs turn off. The output function toggles between light-on and dark-on.

What are the meanings of the LEDs?

Green LED: device operational. Yellow LED: switched output. Red LED: error (bad adjustment, dirty lenses). Yellow+red flashing LEDs: short circuit (2 Hz) or internal error (1 Hz).

How to clean the sensor lenses?

Use a soft non-abrasive cloth to remove dirt. Never use solvents or chemicals that could damage the lens plastic.

What safety precautions should be taken during installation?

Disconnect power before any electrical connection. After a short circuit, check the proper operation of the device. Insert a miniature fuse according to the datasheet if specified.

Can this sensor be used to detect stationary objects?

Yes, in programming mode for stationary objects: first measure without object, then with object. The cell calculates the optimal threshold from the two signals.

How to mount the OL5040 sensor?

Fix the receiver (OLE-...) using the supplied mounting bracket. Align the emitter (OLS-...) precisely opposite the receiver for optimal range.

USER MANUAL OL5040 IFM

Functions and features

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

Range (r): see type label.

Electrical connection

Isolate power, then connect unit (see page 14 or 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 (type OLE-...) in position.

Align the transmitter (type OLS-...) towards the receiver and tighten in the same way. Maximum range is only possible with precise alignment.

Setting the switching threshold (dynamic operation)

- Moving objects in the detection area

The unit detects input signals of various intensity in any sequence and calculates the optimum switching threshold.

1

Press until the red LED flashes

Yellow and green LED's flash alternately (= unit is in the programming mode).

2

Allow the objects to pass through the detection area.Press once.

The yellow and green LED’s go out for approx. 1 s, then flash again alternately.

3	Press once.		The yellow and green LED’s go out for approx. 1s,
			then the green LED is on (= unit is in operating mode).

If the setting of the switching threshold is not possible (e.g. object signal and background signal are about the same), the red LED flashes after step 3. The unit then passes into the operating mode with the switching signal being unchanged.

If the programming button is not activated for 15 minutes during the programming process, the unit passes automatically into the operating mode with the switching threshold being unchanged.

Setting of the maximum sensitivity:

• Go into the programming mode (step 1).
• Interrupt the light beam.
• Press the setting button twice (see steps 2 and 3).

Setting the switching threshold (stationary operation)

- Stationary objects

The unit detects input signals of various intensity in any sequence and calculates the optimum switching threshold.

1

Press until the red LED flashes.

Yellow and green LED's flash alternately (= unit is in the programming mode).

2

Place the object into the detection area *Press once.

The yellow and green LED's go out for approx. 1 s, then flash again alternately.

3	Remove the object *Press once.		The yellow and green LED's go out for approx. 1s,
			then the green LED is on (= unit is in operating mode).

*You can also proceed in reverse order: first setting without the object, then with the object.

If the setting of the switching threshold is not possible (e.g. object signal and background signal are about the same), the red LED flashes after step 3. The unit then passes into the operating mode with the switching signal being unchanged.

If the programming button is not activated for 15 minutes during the programming process, the unit passes automatically into the operating mode with the switching threshold being unchanged.

Setting of the maximum sensitivity:

• Go into the programming mode (step 1).
• Interrupt the light beam.
• Press the setting button twice (see steps 2 and 3).

Programming the output function

1

Press for 10s.

The red LED starts to flash fast after 2 s.Then the yellow and green LED's flash alternately. After 8 s all LED's go off, the output function has changed from light-on mode to dark-on mode (or vice versa).

Operation

Check the safe functioning of the diffuse reflection sensor. Display by LED's.

LED green unit is ready for operation
LED yellow output is switched
LED red	error in object detection,e.g. maladjustment, soiling of the lenses
LED's yellow + red	flashing alternately, 2Hz: output short-circuitedflashing alternately, 1Hz: internal malfunction(output is not switched)

Maintenance

Keep the plastic lenses of the sensor free from soiling.

For cleaning do not use any solvents or cleaning agents which could damage the plastic lenses.
