Frequently Asked Questions - OG5041 IFM

How to install the OG5041 sensor?

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

How to adjust sensitivity for static objects?

1. Activate programming mode by pressing the receiver button for about 2 s until the red LED flashes. The yellow and green LEDs flash alternately. 2. Place the object and press the button once. 3. Remove the object and press again. The cell returns to operating mode.

How to adjust sensitivity for moving objects?

1. Activate programming mode. 2. Let at least two objects pass in the detection zone during measurement (about 1 s) and press once. 3. Let at least two objects pass again and press once. The cell is then adjusted.

What do the different LEDs mean?

Flashing green LED: device operational. Flashing yellow LED: output switched. Flashing red LED: detection error (incorrect adjustment, soiling). Yellow+red LEDs flashing alternately at 2 Hz: short circuit; at 1 Hz: internal error.

What to do in case of detection error (red LED)?

Check the sensitivity adjustment, emitter/receiver alignment, and lens cleanliness. The diagnostic output switches after about 4 s in case of error and resets 4 s after correct detection.

How to clean the sensor lenses?

Clean the lenses without using solvents or products that could damage them. Use a soft, dry cloth or a plastic lens cleaner.

How to connect the sensor electrically?

Disconnect the installation from power. Connect the wires according to the codes: BN = brown (+ supply), BU = blue (- supply), BK = black (output). The power supply must be galvanically isolated and protected against overloads.

What is the range of the OG5041 sensor?

The range (r) is indicated on the sensor label. It depends on the exact model. For optimal range, precisely align the emitter towards the receiver.

How to lock or unlock the sensor programming?

Press the adjustment button for 10 s. The red, yellow, and green LEDs flash alternately, then turn off: the cell is locked. To unlock, press again for 10 s.

What is the diagnostic output for?

The diagnostic output switches in case of detection error (poor detection, misalignment, soiling) after about 4 s, immediately in case of short circuit, or in case of internal error. It resets after the problem is resolved.

USER MANUAL OG5041 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

The device shall be supplied from an isolating source and protected by an overcurrent device such that the limited voltage circuit requirements in accordance with UL 508 are met.

Isolate power, then connect the unit (see page 17 or type label). Core colours (for sensors with cable connection): BN = brown, BU = blue, BK = black.

Programming of the output function by wiring (see page 17 or type label). Load of the function check output (fc output): max. 10mA

Installation

Fix the receiver (type OGE-...) in position.

Align the transmitter (type OGS-...) 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. 接收er 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 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, then 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.

Setting of the sensitivity with moving objects

1	Activate the programming mode of the unit. 接收er 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 (approx. 1s) allow at least two objects to move through the sensing area of the lens. Press once.
	The yellow and green LEDs go out for approx. 1s, then flash again alternately.

3	During the measurement (approx. 1s) allow at least two objects to move through the sensing area of the lens. 接收 Press once.	←→transmitter
	The yellow and green LEDs go out for approx. 1s, then 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.

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).

Locking/Unlocking:

Press for 10s.	The red LED lights for a short time, then the yellow and green LEDs flash alternately; after 10s the LEDs go out, the unit is locked.
Press for 10s.	After 10s the LEDs go out, locking is annulled.

Operation

Check the safe functioning of the through-beam sensor. Display by LEDs and by the function-check output.

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

Function check output

(not for sensors with cable connection)

• 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 lens of the sensor free from soiling. For cleaning do not use any solvents or cleaning agents which could damage the plastic lenses.
