Frequently Asked Questions - OG5043 IFM

How to adjust the sensitivity of the detector?

To adjust the sensitivity, activate programming mode by pressing the button on the receiver for about 2 seconds until the red LED flashes. Then follow the measurement steps with and without an object. For moving objects, allow at least two objects to pass during measurement.

What to do if the red LED flashes?

The red LED flashes in case of a detection error, for example incorrect adjustment or dirty lenses. Clean the lenses and repeat the sensitivity adjustment. If the problem persists, check the alignment of the emitter and receiver.

How to electrically connect the device?

Turn off the installation. Connect the wires according to colors: BN (brown) for positive supply, BU (blue) for negative, BK (black) for switching output. The power supply must be galvanically isolated and protected against overloads.

What is the range of the OG5043 detector?

The range is indicated on the device label. It depends on the configuration. For optimal range, precisely orient the emitter towards the receiver.

How to clean the lenses?

Use a soft, dry cloth to clean the lenses. Never use solvents or harsh products that could damage the plastic.

How to lock or unlock the device?

To lock, press the button on the receiver for 10 seconds until the LEDs turn off. To unlock, repeat the same operation.

What do the different LED flashes mean?

Green LED flashes: device operational. Yellow LED flashes: switched output. Red LED flashes: detection error. Yellow+red flashing alternately at 2 Hz: short circuit; at 1 Hz: internal error (output not switched).

Can I detect transparent objects with this detector?

Yes, but a specific sensitivity adjustment is required. Use programming mode to adjust the sensitivity with the transparent object present.

What power supply should I use?

The power supply must be a galvanically isolated DC voltage source, conforming to UL 508 for the 'limited voltage' category. The exact voltage is indicated on the device label.

How to check the proper operation of the device?

Observe the LEDs: the green LED should flash to indicate the device is operational. If the yellow LED flashes, the output is switched. If red LED, refer to the troubleshooting guide.

USER MANUAL OG5043 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.
