Frequently Asked Questions - OG5100 IFM

How to connect the OG5100 sensor?

Before connection, disconnect the installation from power. Use a galvanically isolated power supply. The wire colors are: BN (brown) = +, BU (blue) = -, BK (black) = output. The output function (PNP or NPN) is programmable by wiring (see label).

What do the sensor 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 adjustment, dirt). Alternating yellow+red flashes indicate a short circuit (2 Hz) or internal error (1 Hz).

How to adjust sensitivity for a static object?

1. Activate programming mode by pressing the button for ~2 s until the red LED flashes. 2. Present the object and press once. 3. Remove the object and press once. The green LED lights up: adjustment complete. If the red LED flashes after step 3, the adjustment failed.

How to adjust sensitivity for moving objects?

1. Activate programming mode. 2. Let at least two objects pass through the detection zone for ~1 s, then press. 3. Repeat step 2 without object. The green LED lights up. If the red LED flashes, the adjustment failed.

What to do if the red LED flashes?

The red LED flashes in case of a detection error: incorrect adjustment or dirty lenses. Check the alignment and clean the lenses. If the problem persists, readjust the sensitivity.

How to unlock the sensor after a lock?

To lock: press the button for 10 s until the LEDs turn off. To unlock: press again for 10 s; after 10 s the sensor is unlocked.

What type of power supply is required?

The power supply must be a galvanically isolated source with overload protection, according to UL 508 for 'limited voltage'. Generally 10-30 V DC.

How to clean the sensor lenses?

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

What is the maximum range of the OG5100?

The range (r) is indicated on the device label. The sensor is factory set to the maximum range for optimal reserve capacity.

What to do in case of a short circuit at the output?

The yellow+red LED flash alternately at 2 Hz. The diagnostic output switches immediately. Eliminate the short circuit; after about 2 s, the error resets automatically.

USER MANUAL OG5100 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.
