Frequently Asked Questions - OG5095 IFM

How to adjust the sensitivity of the OG5095 sensor?

To adjust the sensitivity, press the push button for about 2 s until the red LED flashes. The cell enters programming mode (yellow and green LEDs flash alternately). Then follow the steps: measure with the object then without the object (or vice versa) by pressing once at each step. For moving objects, let at least two objects pass during each measurement of about 1 s.

What do the different LEDs mean?

The green LED flashes: the device is operational. The yellow LED flashes: the output is switched. The red LED flashes: detection error (incorrect setting, soiling). The yellow + red LEDs flash alternately: at 2 Hz = short circuit, at 1 Hz = internal error.

How to clean the sensor lenses?

Clean the lenses with a soft dry cloth. Never use solvents or abrasive products that could damage the plastic lenses.

What is the maximum range of the OG5095 sensor?

The maximum range depends on the application. The typical value is 20 m. Check the label on the sensor for the exact range.

How to connect the sensor electrically?

Disconnect the system from power before connection. Connect the brown (BN) wire to L+, the blue (BU) wire to L- (24 V DC supply). The black (BK) wire is the switching output. The output function (NO/NC) is programmable by wiring.

Can it detect transparent objects?

Yes, thanks to the manual sensitivity adjustment. To detect partially transparent objects, use the programming mode with the object in the beam to adjust the appropriate sensitivity.

How to lock or unlock the settings?

Press the push button for 10 seconds. The red LED lights up briefly, then the yellow and green LEDs flash alternately; after 10 s, they turn off: the settings are locked. Repeat the same operation to unlock.

What to do if the red LED flashes?

A flashing red LED indicates a detection error (object not detected properly, dirty lenses or misalignment). Clean the lenses, check alignment and readjust sensitivity if necessary. If the problem persists, check the wiring.

What is the function of the diagnostic output?

The diagnostic output switches in case of an error: after about 4 s in case of incorrect detection (soiling, misalignment), immediately in case of short circuit, or in case of internal error. It resets after the fault is corrected.

How to mount the OG5095 sensor?

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

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.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 sensitivitywithobject.Press once.
	The yellow and green LEDs go out for approx. 1s,then flash again alternately.

3	Set the sensitivitywithoutobject.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.
	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.
	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.
	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.
