3 Functions and features

3.1 General notes

The unit is used as a photoelectric distance sensor.

The unit continuously detects the distance to the object and the reflectivity of 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 values are shown in a 7-segment display and transferred via IO-Link. Two measured values are generated.

Measured distance value:

Distance from the front lens of the sensor to the target.

With the basic setting, the status of switching output OUT1 (pin 4) is determined from this measured value.

Object reflectivity:

Reflexivity of the target.

With the basic setting, the status of switching output OUT2 (pin 2) is determined from this measured value.

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 Applications

• The photoelectric distance sensor measures distances between 8...165 cm and object reflectivities between 0...999 %.
• It has a background suppression of up to 20 m.

The distance between the sensor and the background must be limited to max. 20 m. Otherwise measured values can be ambiguous → 5.1.

3.3 Installation instructions

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 direct radiation of light sources. 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] ( → 10.3.7 Set the fault suppression time).

4 Functions

This photoelectric distance sensor has two switching outputs OUT1 / OUT2. With the basic setting (logic function = OFF), the status of the switching outputs is determined by one measurement parameter each.

1. Status OUT1 (pin 4) is determined on the basis of the measurement parameter "distance".
2. Status OUT2 (pin 2) is determined on the basis of the measurement parameter "reflectivity".

4.1 Output function hysteresis

The hysteresis keeps the switching status of the output (distance or reflectivity) stable if the measured value varies about the sensing range or the switching reflectivity. Both outputs (OUT1 and OUT2) can be set as hysteresis function ( → 10.2.5 Set the switch point for the hysteresis function OUT1 /OUT2).

The object is detected if the switch point (distance) is not reached (object is "near").

The object is detected if the switch point (reflectivity) is exceeded (object is "bright").

4.2 Output function window

The window function allows monitoring of a defined acceptable range (distance or reflectivity). Both outputs (OUT1 and OUT2) can be set as window function → 10.2.8.

Hystereses set automatically by the sensor ensure that the switching status of the output remains stable at the window limits. Please refer to the data sheets for the hystereses.

4.3 Switch off the laser

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

Input signal at pin 5	Laser
Low / not used	on
High	off

4.4 Logic operator of the switching outputs

The sensor makes it possible to link the switching outputs (distance and reflectivity) logically.

Three options are available:

Logic	Description
OFF	no logic block
AND	AND operator of OUT1 and OUT2
OR	OR operator of OUT1 and OUT2

Thanks to the logic operators, both measurement parameters can be used for the decision to switch on a switching output. Wiring complexity can be reduced.

Example:

AND operator on [OUT1] (LG1= AND), [OUT1]=[OUT2]=[hno].

[OUT1] is switched if

- measured distance value < set switch point [SP1] and measured reflectivity value > set switch point [SP1]

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 20 m. Objects outside the measuring range will be suppressed up to the limit of the unambiguity range (20 m).

Reflecting objects in the direct beam path of the sensor - also in the range < 20 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.

Pieces	Mounting accessories	Art. no.
2	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. OGD582 and OGD583: cULus, Supply Class 2

▶ Disconnect power.
▶ Connect the unit as follows:

	OGD582 / OGD583 PNP

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).

9 Operating modes

9.1 Run mode

The run mode is the normal operating mode.

After power on the unit is in the Run mode. It carries out its monitoring function and generates output signals according to the set parameters.

The display indicates the current distance or the object reflectivity, the yellow LEDs signal the switching status of the outputs.

The measuring distance is displayed in [cm].

• Value range 0...99.9 cm with one decimal place (mm resolution)
• Value range 100...165 cm without decimal place (cm resolution)

The object reflectivity is displayed in [%]:

• Value range = 0...999

• A value of 100% corresponds to the reflectivity of a white Kodak Gray Card if the sensor is aligned vertically to the object.
• A value of 20% corresponds to the reflectivity of a grey Kodak Gray Card if the sensor is aligned vertically to the object.

Reflective surfaces can generate values considerably larger than 100%.

Timeout

If no button is pressed for 15 s during the setting procedure, the unit returns to the Run mode with unchanged values.

10.2 Configuration of the basic settings

10.2.1 Configure OUT1 / OUT2

▶ Select [OU1] / [OU2] and set the switching functions. Switching functions:• [Hno] = hysteresis function / normally open• [Hnc] = hysteresis function / normally closed• [Fno] = window function / normally open• [Fnc] = window function / normally closed• [OFF] = switching output is deactivated▶ Confirm with [ENTER].

10.2.2 Hysteresis function for OUT1

The hysteresis keeps the switching status of the output stable if the measured value varies about the sensing range. The selected switch point [SP1] is the set point. The reset point is automatically set above the selected switch point [SP1] by the sensor. The nominal distance between set point 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).

1

2

[SP1] = 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 on.

Switching status of the outputs

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

10.2.3 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 [SP1] has been selected.

Very dark background = high hysteresis is selected.

Very bright background = small hysteresis is selected.

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

A bright background enables the detection of smaller objects.

10.2.4 Hysteresis function for OUT2

The hysteresis keeps the switching status of the output stable if the measured value varies about the reflectivity value. The selected switch point [SP2] is the set point. The reset point is automatically set above the selected switch point [SP2] by the sensor. The nominal reflectivity difference between set and reset point is the hysteresis which is indicated in the data sheet.

Example Hno

1. For the output function [Hno] the output switches when the object reflectivity increases and when the set point (A) is reached.
2. When the object gets darker, the output does not switch back before the value is below the reset point (B).
   The reset point (B) is smaller than the set point (A).

1: Laser beam

A: Set point "bright" [SP2]

2: Direction of movement object

B: Reset point

If the output function [Hnc] has been selected, the set and reset points are reversed. The output switches on if the object reflectivity is decreased. If the object reflectivity is increased, the output switches off.

10.2.5 Set the switch point for the hysteresis function OUT1 /OUT2

▶ In [OU1] / [OU2], select the output function [Hno] or [Hnc].
▶ Confirm with [ENTER].
▶ Select [SP1] and set the switch point.
▶ Confirm with [ENTER].

10.2.6 Window function for OUT1

It is possible to define a window for the object recognition for output (OUT1).

Switches when the object is detected

[nP1] = switch point "near"; [FP1] = switch point "far"; FE = window

If the measured value is between the switch point "near" [nP1] and the switch point "far" [FP1], the output is switched on (when [OU1] = [Fno]).

Switches off when the object is detected

[nP1] = switch point "near"; [FP1] = switch point "far"; FE = window

If the measured value is between the switch point "near" [nP1] and the switch point "far" [FP1], the output is switched off (when [OU1] = [Fnc]).

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

The reset points are set dynamically by the sensor → 10.2.3 Dynamic hysteresis.

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

Condition: nP1 < FP1

e.g. teaching of nP1 > FP1 is not adopted by the sensor.

10.2.7 Window function for OUT2

It is possible to define an object reflectivity window for the object detection for output (OUT2).

1: Laser beam
2: Direction of movement object
3: Window

A: Switch point "bright" [bP2]
B: Switch point "dark" [dP2]

Switches when the object is detected

If the measured value is between switch point "bright" [bP2] and switch point "dark" [dP2], the output is switched on (when [OU2] = [Fno]).

Switches off when the object is detected

If the measured value is between switch point "bright" [bP2] and switch point "dark" [dP2], the output is switched off (when [OU2] = [Fnc]).

The parameters [bP2] and [dP2] can also be set via the teach function. The reset points are set dynamically by the sensor.

The minimum distance between [bP2] and [dP2] is 1 %.

Condition: dP2 < bP2

e.g. teaching of dP2 > bP2 is not adopted by the sensor.

Switching status of the outputs for OUT2

Output function	Object reflectivity (R)	Switching status
[Fno]	R < [dP2]	open
	R > [bP2]
	[dP2] < R < [bP2]	closed
[Fnc]	R < [dP2]	closed
	R > [dP2]
	[dP2] < R < [bP2]	open
Both window limits ([bP2] and [dPx]) work with a switching hysteresis → 10.3.1 Set the display / Example of output function [Hno].
