Warning sign

3 Intended use

▷ The diffuse reflection sensor detects objects and materials without contact and indicates their presence by a switching signal.

4 Installation

▶ Align the diffuse reflection sensor to the object to be detected.
▶ Secure it to a bracket.

The objects to be detected should move transversely to the lens of the sensor.

▶ In case of other directions of movement it should be tested before whether safe switching is guaranteed.

Object shiny

▶ In case of shiny object surfaces and less shiny background surfaces the sensor should be mounted at an angle of approx. 5 to 10° .

Background shiny

▶ In case of shiny background surfaces and less shiny object surfaces the sensor should be mounted vertically to the background surface.

7.2.3 Parameter setting tools

You will find all necessary information about the required IO-Link hardware and software at www.ifm.com.

7.2.4 Functions

With IO-Link all functions and measured data are available that can also be accessed via the display and pushbuttons on the unit.

All functions are described in detail in the IODD.

7.2.5 Adjustable parameters

Among others, the following parameters can be set via IO-Link.

You will find the IODDs necessary for the configuration of the IO-Link unit and detailed information about sensor values, diagnostic information and parameters in the overview table at www.ifm.com.

Either the object can be set first and then the background, or the other way around.

7.2.7 Set range by means of background

If the object is not available, the range can be set using only the background.

The switching characteristics of the diffuse reflection sensor are most reliable if the range is set using the background and the object. ( → Set range by means of background and object ☐ 11)

▶ Start the parameter setting software.
▶ Align the diffuse reflection sensor to the background (fig. 6).
▶ Click the button [Teach Custom - SP1 without target] in the parameter setting software.
▷ The switch point [SP1] is just in front of the background (fig. 7).

7.2.8 Read distance value

Distance values can also be determined via the IO-Link function.

▶ Start the parameter setting software.
▶ Change parameter [ModE] from [Switching] to [Measuring].
▷ The sensor transmits distance values to the parameter setting software.

7.2.9 Set maximum range

▶ Start the parameter setting software.
▶ Align the diffuse reflection sensor to an empty area without object or background.
The diffuse reflection sensor must not receive any light from the object or the background.
▶ Click the button [Teach Custom - SP1 without target] in the parameter setting software.

8 Operation

▶ Check whether the unit operates correctly.
The green LED is lit when the supply voltage is applied and there is sufficient excess gain.
▷ Setting the dark-on mode: The output is switched / the yellow LED is on when an object is detected.
▷ Setting the light-on mode: The output is switched / the yellow LED is on when no object is detected.

9 Maintenance, repair and disposal

▶ Keep the lenses of the sensor free from soiling.
▶ For cleaning do not use any solvents or cleaning agents which could damage the plastic parts.
▶ After use dispose of the unit in an environmentally friendly way in accordance with the applicable national regulations.
