3 Intended use

The fibre-optic sensor is used to connect fibre optics of the FE-11, FT-11, FE-00 and FT-00 type. The E21327 adapter is required for the FE-00 and FT-00 types. The range or sensing range varies depending on the fibre optics used.

Objects and materials can be detected without contact via the fibre optics. The fibre-optic sensor evaluates the signal and outputs a corresponding switching signal.

4 Function

Depending on the fibre optics connected, the fibre-optic sensor can be used as an energetic diffuse reflection sensor or as a through-beam system.

4.1 Measuring principle

Energetic diffuse reflection sensor

Diffuse sensor The transmitter and receiver are integrated in the same sensing head.The objects are detected by reflection of the light beam based on the energetic, the triangulation or the time-of-flight principle.Energetic principle:The range depends on the energy of the reflected light. Depending on the object surface the light is reflected more or less well:good reflection: smooth / light object.poor reflection: rough / dark object.

1: Transmitter and receiver2: Object

Through-beam system

Through-beam sensor The transmitter and	receiver are integrated in different fibre-optic heads. The objects are detected by interruption of the light beam.
		1: Transmitter2: Receiver

4.2 Operating modes

4.2.1 Switching mode

In switching mode, the sensor is directly connected to the process control unit and transmits the state via the switching output.

If the set switching threshold is exceeded/not reached, this is signalled by means of switching signals on the switching output.

4.2.2 Operation with IO-Link master

If the sensor is connected to an IO-Link master, parameter setting and data recording can be done completely via IO-Link.

IO-Link is a communication system for the connection of intelligent sensors and actuators to automation systems. IO-Link is regulated in the IEC 61131-9 standard.

General information about IO-Link can be found at io-link.ifm.

Auto SP tracking function

The process data value (PDV) changes between two points (with and without object). The setpoint (SP) lies between these two points.

Due to environmental factors such as dust deposits or water vapour condensation on the fibre optics, the process data values (with and without object) may decrease. When the level drops below the SP, the output no longer switches. At this point, maintenance is required and the fibre optics need to be cleaned.

However, with the Auto SP tracking function, the set value is adjusted based on the last process data values which are used to generate an average value, aka mean value (SPmonitor). The averaging allows for longer operating intervals of the sensor. Consequently, the maintenance requirements of the fibre optics are reduced.

PDV: Process data value 5: Auto SP tracking = [ON]

SPmonitor: Mean value of the process data values 6: Auto SP tracking = [ON]
	Maintenance is not required.
	Maintenance is recommended.
1: Setpoint (SP) 7: Auto SP tracking = [ON]	Decreasing process data value (PDV). The message "Critical" is generated via IO-Link. The sensor cannot switch reliably.
	Maintenance is required.
2: Warning 8: Auto SP tracking = [ON]	Maintenance is required.
	Maintenance is required.
3: Critical value 9: Additional maintenance-free period if Auto SP track-ing = [ON]
4: Minimum possible setpoint (SPmin)

The values for the Auto SP tracking function are saved once an hour. In the event of a power failure, the last stored values are used.
