3 Functions and features

3.1 General notes

The unit is used as an optical distance sensor.

The unit continuously detects the distance to the object and generates output signals according to the parameter settings.

• 2 switching outputs are available. They can be set separately. Switch points can either be set or taught.
• The measured value is shown in a 7-segment display and transferred via IO-Link. Two measured values are generated.

Measured distance value:

The distance from the sensor to the target provides the primary measured value.

Object reflectivity:

The reflexivity of the target is also determined.

• This measured value is suitable for monitoring and detecting sensor soiling.
  The unit uses a laser diode as light source and creates a light spot. This makes it possible to detect small objects.

The light spot should hit the object or the background. Intermediate states may lead to faulty measured values.

3.2 Application areas

• The optical distance sensor measures distances between 25...300 mm.
• It has a background suppression of up to 19.2 m.

The distance between the sensor and the background must be limited to max. 19.2 m. Otherwise measured values can be ambiguous. → 5.1

3.3 Installation notes

3.3.1 Avoidance of soiling and ambient light

Preferably align photoelectric sensors with the front lens facing downwards or parallel to the earth's surface.

Background:

• Photoelectric sensors are sensitive to ambient light. Everyday light sources (lamps, sun) radiate from above.
  • Photoelectric sensors react sensitively to soiling, as it reduces the excess gain.

Dust deposits can be reduced by downwards or sideways orientation. This allows for longer cleaning intervals.

Make sure that sensors installed with their front lens facing upwards are not oriented towards roof windows or ceiling lamps.

3.3.2 Avoidance of mutual interference

Photoelectric sensors should be installed with a sufficient distance between each other. This particularly applies if the detection range of the two sensors partly intersects.

Background:

- Both sensors have a detection range. This means that the laser light spot of a sensor can be received by its neighbouring sensor. This may lead to the falsification of the measured values and result in incorrect switching.

Mutual interference can be avoided by placing the sensors slightly tilted. Align the light spots so that they impinge as far away from each other as possible.

3.3.3 Sensor alignment to moving objects

Photoelectric sensors have to be installed in a way to ensure that the object is moved into the detection range of the sensor from the side or from the bottom.

Background:

• When the object approaches from the top, it initially covers part of the receiver lens without being detected by the light spot. So far, the sensor only "sees" the background.
• If the object completely covers the receiving lens without the light spot detecting the object, the sensor cannot "see" the background any more. The sensor provides the error indication [--], as no signal is detected any more. When the object approaches further, it is eventually detected.

Avoidance of the error indication by increasing the parameter [dFO] ( → 10.3.2 Setting of the fault suppression time for switching outputs).

4 Functions

4.1 Output function hysteresis

The hysteresis keeps the switching state of the output stable if the measured value varies about the sensing range. Both outputs (OUT1 and OUT2) can be set as hysteresis function ( → 10.2.4 Hysteresis function).

4.2 Output function window

The window function enables the monitoring of a defined acceptable range. Both outputs (OUT1 and OUT2) can be set as window function → 10.2.8.

4.3 Switch off the laser

The laser can be switched off via the input on pin 5.

Input signal at pin 5		Laser
PNP	NPN
Low / not used	High / not used	On
High	Low	Off

5 Installation

5.1 Installation conditions

▶ Install the unit so that the object to be detected is within the specified measuring range.

The unambiguity range of the sensor is fixed to 19.2 m. Objects outside the measuring range will be suppressed up to the limit of the unambiguity range (19.2 m).

Reflecting objects in the direct beam path of the sensor – also in the range < 19.2 m – are to be avoided by the customer. Otherwise the measured values can be ambiguous.

5.2 Mounting accessories

The unit is supplied with mounting accessories.

2x	Metal lock nuts	E10027

6 Electrical connection

The unit must be connected by a qualified electrician.

▶ The national and international regulations for the installation of electrical equipment must be adhered to.
▶ Ensure voltage supply to EN 50178, SELV, PELV. OGD592 and OGD593: cULus, Supply Class 2

▶ Disconnect power.

▶ Connect the unit as follows:

	OGD592 PNP	OGD593 NPN

Core colours of ifm sockets:
1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4 = BK (black), 5 = GR (grey).

6.1 Operation with IO-Link master

The unit is compatible with IO-Link master port class A (type A).

For operation with IO-Link master port class B (type B) observe the following:

As a standard, the unit is not compatible with master port class B (type B). Pin 2 (OU2) and pin 5 (IN1) are used for manufacturer-specific functions. That means that the main supply voltage of the unit and the additional voltage supply (master port class B on pins 2/5) are not electrically isolated.

With the following configurations the unit can be used with master port class B:

• Connect unit and IO-Link master via 3 wires: Connect pins 1, 3 and 4 of the unit with the IO-Link master (do not connect pins 2 and 5).
• Connect unit and IO-Link master via 4 wires: Deactivate pin 2 (OU2) via IO-Link (setting OU2 = "off") and connect pins 1, 2, 3 and 4 of the unit with the IO-Link master (do not connect pin 5).

10.2.4 Hysteresis function

The hysteresis keeps the switching state of the output stable if the measured value varies about the sensing range. The selected switch point [SPx] is the set point. The reset point is automatically set above the selected switch point [SPx] by the sensor. The nominal distance between switch-on pint and reset point is the hysteresis, it is indicated in the data sheet. The hysteresis depends on the reflectivity of the background.

Example Hno

1. For the output function [Hno] the output switches when the object approaches and when the set point (A) is reached.
2. When the object is removed again, the output does not switch back before the reset point (B) is exceeded.
   The reset point (B) is above the set point (A).

2

[SPx] = switch point; A = set point; B = reset point

If the output function [Hnc] has been selected, the set and reset points are reversed. The output switches off when the object approaches. When the object is removed again, the output switches.

Switching status of the outputs

Output function	Object distance (D)	Switching status
[Hno]	D < [SPx]	Closed
	D > [SPx]	Open
[Hnc]	D < [SPx]	Open

OU1OU2LS1SP1

10.2.7 Dynamic hysteresis

The measured values detected by the sensor vary depending on the situation. The highest fluctuation of measured values occurs in case of a small signal to noise ratio. This is the case when very dark targets are detected and when there is very much ambient light. Therefore, the reset point is automatically set by the sensor after [SPx] has been selected.

Very dark background = high hysteresis is selected.

Very bright background = small hysteresis is selected.

The minimum distance between object and background can be reduced if the background is very bright (e.g. white).

A bright background enables the detection of smaller objects.

10.2.8 Window function

It is possible to define a window for the object recognition for each of the two outputs (OUT1 / OUT2).

Switches when the object is detected

[nPx] = switch point "near"; [FPx] = switch point "far"; FE = window

If the measured value is between the switch point "near" [nPx] and the switch point "far" [FPx], the output is closed (when [OUx] = [Fno]).

Switches off when the object is detected

[nPx] = switch point "near"; [FPx] = switch point "far"; FE = window

If the measured value is between the switch point "near" [nPx] and the switch point "far" [FPx], the output is open (when [OUx] = [Fnc]).

The parameters [nP1] and [FP1] can also be set via the teach function.

The reset points are set dynamically by the sensor → 10.2.7 Dynamic hysteresis.

The minimum distance between [nP1] and [FP1] is 1 mm.

Condition: nP1 < FP1

The teaching of nP1 > FP1 will not be adopted by the sensor.

Switching status of the outputs

Output function	Object distance (D)	Switching status
[Fno]	D < [nPx]	Open
	D > [FPx]
	[nPx] < D < [FPx]	Closed
[Fnc]	D < [nPx]	Closed
	D > [FPx]
	[nPx] < D < [FPx]	Open
Both window limit values ([nPx] and [FPx]) work with a switching hysteresis → 10.2.4 Hysteresis functionexample for output function [Hno].
