nOutput 1 — flow: switching output or IO-Link interface
nOutput 2 — temperature: switching output
nOutput type: configurable NC/NO contact
nConfigurable output configuration: PNP/NPN/Auto Detection
4.3 Operating and display functions
The user can configure and operate the device via three touch pads ([ENTER], [MODE] and
[SET]) on the front. An 11-digit LED bar aids parameterization and displays the current flow or
temperature values (as selected) in operating mode. Five LEDs indicate the switching status
and device status.
4.4 Operating principle
The flow sensors operate calorimetrically. The function is based on the thermo-dynamic prin-
ciple. When the medium is flowing, thermal energy is dissipated at the sensor. The resulting
temperature on the sensor is measured and compared to the medium temperature. The flow
status can be derived directly from the determined temperature difference: The greater the en-
ergy dissipation, the higher the flow speed or flow rate.
4.5 Functions and operating modes
The FS100…-2UPN8 compact flow sensors monitor the flow speed of liquid media (type
FS1…-…L-) as well as the media temperature to determine whether configurable limit values
are exceeded or undershot. The devices show the recorded flow and temperature values on the
front via status LEDs and an LED bar. The two switching outputs can optionally be used as nor-
mally open or normally closed contacts. If the auto detection function is activated, the sensor
automatically detects and activates the relevant type of output (PNP/NPN). When operating
with an IO-Link master, one of the two digital outputs can also be used as a bidirectional, serial
IO-Link interface.
4.5.1 Flow monitoring
The flow speed is detected by a calorimetric sensor in the flow channel and evaluated by the in-
tegrated evaluation electronics. The current flow value is displayed via the LED bar and—when
connected to an IO-Link master—is output via a communication signal.
The switching output Out1 (Flow) changes its switching status when the set switching point is
reached as a result of the reducing flow rate. If the flow rate increases, the switching status
changes when the switching point is undershot by the hysteresis.

Hans Turck GmbH & Co. KG | T [phone] | [email protected] | www.turck.com V02.00 | 2022/08 | 10
4.5.2 Temperature monitoring
The calorimetric measurement method used by the sensors not only monitors the flow speed,
but also measures the approximate temperature of the media. Both process variables are recor-
ded and evaluated independently of each other. The current temperature is displayed via the
LED bar and—when connected to an IO-Link master (FS…2UPN8)—is output via a communica-
tion signal. The current temperature appears on the display when the [SET] touchpad is pressed
and held in display mode.
The switching output Out2 (Temp) is used for temperature monitoring. The devices change
their switching status when the set switching point is reached due to a rising temperature. If
the temperature drops, the switching status changes when the switching point is undershot by
the hysteresis.
4.5.3 IO-Link mode
In order to operate in IO-Link mode, the device must be connected to an IO-Link master. When
the port is configured in IO-Link mode, bidirectional IO-Link communication takes place
between the IO-Link master and the device. To make this possible, the device is integrated via
an IO-Link master at the control level. First the communication parameters are exchanged, and
then the cyclic data exchange of process data (objects) starts.
In IO-Link mode, both cyclic and acyclic communication services for exchanging device data
(parameter values, identification data and diagnostic information) are available. The IO-Link
master always sends a request to the device first, and then the device responds. This is the case
both when the data is written into the device and read from the device.
4.5.4 SIO mode (standard I/O mode)
In standard I/O mode no IO-Link communication takes place between the device and the mas-
ter. The device only transfers the switching state of its binary outputs and can also be run via a
fieldbus device or controller with digital PNP or NPN inputs. An IO-Link master is not required
for operation.
The device parameters can be set via IO-Link and then operated at the digital inputs with the
appropriate settings in SIO mode. Not all functions and properties of the device can be used in
SIO mode.

7 Commissioning
After switching on the operating voltage, the DeltaFlow function monitors the warm-up phase
of the sensor. During this phase, the LED indicator bar flashes yellow and the two output LEDs
FLOW and TEMP are switched off.
The warm-up phase is deemed to be complete:
nIf the period of 30seconds that is allotted for the warm-up phase has elapsed.
nIf the system is in a stable condition, i.e. the change in flow rate is sufficiently small.
After the warm-up phase, the device is ready for use and automatically switches to display
mode for the flow speed.

Automatic detection function
The Automatic detection function supports the error-free configuration of the sensor for con-
necting to the remote I/O environment: The sensor automatically activates the output signal
that corresponds to the signal type of the connected input card. The Automatic detection func-
tion is active by default. The output can also be set selectively as required via the IO-Link inter-
face.
