Frequently Asked Questions - OL5016 IFM

How to connect the OL5016 sensor?

Disconnect the installation from power before any connection. Use the removable terminal block (for cable gland) or the connector depending on the model. After connecting the wires, snap the terminal block into place. A miniature fuse may be necessary.

How to adjust sensitivity for static objects?

1. Press the receiver button for about 2s until the red LED flashes. 2. In programming mode (yellow and green LEDs flash), press once with the object in the detection zone. 3. Press once without an object. The green LED lights up after 3s, adjustment is complete.

How to adjust sensitivity for moving objects?

1. Activate programming mode (long press 2s). 2. Let at least two objects pass through the zone, then press once. 3. Repeat the operation (let two objects pass) and press once. The green LED lights up after 3s.

What to do if sensitivity adjustment is not possible?

If after step 3 the red LED flashes for about 2s, it means the object and background signals are too similar. The sensor then returns to operating mode without changing sensitivity. You can try again or use maximum sensitivity.

How to program the output function (NC/NO)?

Press the receiver button for about 10s until all LEDs turn off. After 2s, the red LED flashes quickly, then the yellow and green LEDs flash alternately. After 8s, all LEDs turn off and the output changes from NC to NO or vice versa.

What do the different LEDs mean?

Green LED steady: device operational. Yellow LED steady: output switched. Red LED steady: detection error (incorrect adjustment, dirty lenses). Yellow and red flash alternately at 2 Hz: output short circuit. At 1 Hz: internal error (output not switched).

How to clean the sensor lenses?

Use a soft, dry cloth. Do not use solvents or abrasive products that could damage the plastic lenses.

What to do in case of output short circuit?

The diagnostic output switches immediately in the event of a short circuit and resets about 2s after the fault is cleared. Check the wiring and load, and replace the fuse if necessary.

Is the sensor ready to use without adjustment?

Yes, the through-beam photoelectric sensor is delivered in 'plug and play' mode with maximum sensitivity. It works immediately. Adjustments are only necessary for partially transparent objects or special conditions.

How to mount the sensor?

Mount the receiver (OLE-...) with the mounting bracket. Align the emitter (OLS-...) towards the receiver and fix it in the same way. Precise alignment is necessary for optimal range.

USER MANUAL OL5016 IFM

Barrage photoelectrique OL

Function 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 17/18 or type label). Load of the function check output (fc output): max. 10mA.

The units with cable gland have a removable terminal block with screw terminals (screws are at the base of the terminal block).

After connection of the wires the terminal block must be reinserted. Note: insert a miniature fuse according to the technical data sheet, if specified. Recommendation: check the unit for reliable function after a short cirucit.

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.

NB: Commissioning

The through-beam sensor is supplied ready to operate (plug and play) set at the max. sensing range. This is sufficient if the through-beam sensor can operate with maximum excess gain (highest contrast). The following setting procedures should only be necessary in less straightforward applications, for example if partly transparent objects must be detected.

Setting of the sensitivity with stationary objects

1	Activate the programming mode of the unit. receiver transmitter Press for about 2s until the red LED flashes.
	The red LED goes out; the yellow and green LEDs flash alternately. The unit is in the programming mode.

2	Set the sensitivity with object. receiver transmitter Press once.
	The yellow and green LEDs go out for approx. 1s, then flash again alternately.
3	Set the sensitivity without object. receiver transmitter Press once.
	The yellow and green LEDs go out for approx. 1s, after approx 3s the green LED is on. The unit is in the operating mode.

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

If the setting of the sensitivity is not possible (e.g. object signal and background signal are about the same), the red LED flashes after step 3 for approx. 2s. The unit then passes into the operating mode with the sensitivity being unchanged.

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

Setting of the sensitivity with moving objects

1	Activate the programming mode of the unit. receiver transmitter Press for about 2s until the red LED flashes.
	The red LED goes out; the yellow and green LEDs flash alternately. The unit is in the programming mode.
2	During the measurement (about 1s) allow at least two objects to move through the detection area. receiver transmitter Press once. The yellow and green LEDs go out for approx. 1s, then flash again alternately.

3	During the measurement (about 1s) allow at least two objects to move through the detection area. receiver transmitter Press once. The yellow and green LEDs go out for approx. 1s, after approx. 3s the green LED is on. The unit is in the operating mode.

If the setting of the sensitivity is not possible (e.g. object signal and background signal are about the same), the red LED flashes after step 3 for approx. 2s. The unit then passes into the operating mode with the sensitivity being unchanged.

If the setting button is not activated for 15 minutes during the programming process, the unit passes automatically into the operating mode with the sensitivity 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

receiver Press for 10s.

The red LED starts to flash fast after 2s. Then the yellow and green LEDs flash alternately. After 8s all LEDs 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 unit. Display by LEDs and by the function check output.

LED green is lit U	Unit is ready for operation.
LED yellow is lit O	Output is switched.
LED red is lit	Error in object detection, e.g. maladjustment, soiling of the lenses.
LEDs yellow + red	Flash alternately, 2 Hz: output short-circuited. Flash alternately, 1 Hz: internal malfunction (output is not switched).

Function check output

(only for sensors with DC power supply)

• Switches in the case of incorrect object detection (error in object detection, maladjustment, soiling of the lenses) after approx. 4 s, it switches back approx. 4 s after the object is again correctly detected.
• Immediately switches in the case of a short circuit of the switching output, it switches back approx. 2 s after the fault has been rectified.
• Immediately switches in the case of an internal fault, it is only switched back by turning off the operating voltage and then on again.

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.
