2 Safety instructions
• Please read the product description prior to set-up of the unit. Ensure that the
product is suitable for your application without any restrictions.
• Improper or non-intended use may lead to malfunctions of the unit or to un-
wanted effects in your application.
• That is why installation, electrical connection, set-up, operation and mainte-
nance of the unit must only be carried out by qualified personnel authorised by
the machine operator.

3 Functions and features
3.1 Application area
The unit monitors the flow and the temperature of liquid and gaseous media.
3.2 Flow and temperature monitoring with output S1
The unit detects the flow velocity and the current medium temperature. It links the
two measured signals (logical function: AND) and switches output S1:
output S1
flow≥switchpointSP1andmediumtemperature≥switchpointSP2 closed
•flow < SP1 or
•temperature < SP2 or
•flow < SP1 and temperature < SP2
open
This applies to the unit on delivery: output = normally open. If necessary you can change the
outputstonormallyclosedfunction(→8.2).Itthenapplies:outputS1openifflow≥switch
pointSP1andmediumtemperature≥switchpointSP2.
On flow monitoring function:
• If the flow velocity increases, signal SP1 changes when the switch point is
reached.
• If the flow velocity falls again, signal SP1 changes when the value “SP1 minus
hysteresis” is reached.
The hysteresis changes with the flow speed and it is essentially influenced by
the set monitoring range.
It is 2...5 cm/s for the setting 5...100 cm/s (= factory setting), it increases with
higher flow speeds.
3.3 Temperature monitoring with output S2
The unit detects the current medium temperature and switches the output S2:
- OutputS2closedifmediumtemperature≥SP2/outputopenifmedium
temperature < SP2.
This applies to the unit on delivery: output = normally open. In case of need you
canchangetheoutputstonormallyclosed(→8.2).Itthenapplies:outputS2
openifmediumtemperature≥SP2.

4 Installation
Using process adapters the unit can be adapted to different process connections.
• Adapters have to be ordered separately as accessories.
A correct fit of the unit and ingress resistance of the connection are only
ensured using ifm adapters.
• For small flow rates ifm adapter blocks are available.
4.1 Installation location
General

•The sensor tip is to be completely sur-
rounded by the medium.
•Insertion depth of the sensor: minimum
12 mm.
Recommended
•For horizontal pipes: mounting from
the side.
•For vertical pipes: mounting in the rising
pipe.
Conditional
•Horizontal pipe /mounting from the bot-
tom: if the pipe is free from build-up.
•Horizontal pipe /mounting from the
top: if the pipe is completely filled with
medium.
To avoid
•The sensor tip must not be in contact
with the pipe wall.
•Do not mount in downpipes that are
open at the bottom!

4.2 Sources of interference in the pipe system
Components integrated in the pipes, bends, valves, reductions, etc. lead to turbu-
lence of the medium. This affects the function of the unit.
Recommendation: Adhere to the distances between sensor and sources of
interference:

1: Operation display
•The green LEDs indicate the current flow (the LEDs 0 to 9 represent the range between
no flow and maximum flow).
•A lighting LED indicates the position of the flow switch point (S1) (orange = output
closed, red = output open).

(Formediaotherthanwater→8.1:Lowflowadjustment).
►Switch on the supply voltage.
> All LEDs light and go out again step by step. During this time the output S1 is
closed (if configured as normally open). The unit is in the operating mode.
►Let the normal flow circulate in the installation.
►Check the display and determine further actions.

7.1 Change switch point SP1 (flow monitoring), optional
For the factory setting the switch point is at LED 7. A change makes sense if:
• the display shows example 2.
• the flow fluctuates much or pulsates.
• if a faster response time of the unit is requested (low switch point = fast re-
sponse with rising flow, high switch point = fast response with falling flow).
►Briefly press the pushbutton .
> The switch point LED flashes.
►Press the pushbutton or as often as required. Each press of the push-
button shifts the LED by one position in the indicated direction.
Note: If no pushbutton is pressed for 2 s, the unit returns to the operating mode
with the newly set value.

7.2 High flow adjustment (optional)
The unit determines the existing flow as normal flow and adapts the display repre-
sentation (all LEDs except the switch point LED light green).
►Let the normal flow circulate in the installation.
►Press the pushbutton and keep it pressed.
> LED 9 lights, after approx. 5 s it flashes.
►Release the pushbutton.
The unit is now adapted to your flow conditions. It passes into the operating mode,
the display should now show example 1.
Note: The adjustment affects the switch point: It is increased proportionally (maxi-
mum up to LED 7).
7.3 Set the switch point SP2 (temperature)

In addition the current temperature is indicated in steps of 10°C by red LEDs.

pushbutton shifts the flashing LED (1st digit) by one position in the indicated
direction.

is constantly lit (2nd digit) moves on by one position to the right (if pushbutton
is used).

Note: 5 s after the last press of the pushbutton the display returns to the tempera-
ture and switch point display mode (step 1). After another 5 s the unit goes to the
operating mode with the newly set value.
8 Additional settings (optional)
8.1 Low flow adjustment
If the unit is used in media other than water, you should additionally adapt the unit
to the minimum flow.
Note: The following adjustment must only be carried out after the high flow adjust-
ment.
►Let the minimum flow circulate in the installation or ensure flow standstill.
►Press the pushbutton and keep it pressed.
> LED 0 lights, after approx. 5 s it flashes.
►Release the pushbutton. The unit adopts the new value and passes into the
operating mode.
8.2 Configure the switching outputs
The unit is delivered as normally open. In case of need you can change the
outputs to normally closed (the changing applies to both outputs):
►Press the pushbutton for at least 15 s.
> LED 0 lights, after approx. 5 s it flashes.
