5 Assembly
Danger of injury from uncontrolled operation
If the system is under voltage and/or pressure during assembly of the Durchflusssensor, this
may lead to uncontrolled responses and, as a result, to injuries to personnel or damage to the
system.
O
Always make sure the relevant system component is not under pressure or voltage before
connecting pneumatics or electrics for the Durchflusssensor.
Installation Conditions
W
Make sure that the assembly location is easy to access and free from vibrations.
W
Observe a minimum free space of 150 mm for the transmitter unit of the flow rate sensor.
W
Observe the ambient temperature (see "13 Technical Data") and the heat dissipated by the
measuring medium.
W
The measuring medium must at least correspond to purity class 3:4:4 or better, in
accordance with ISO 8573-1:2010.
W
The measuring medium and the ambient air must not condensate.
W
In compressed air networks, mount the flow rate sensor downstream of the air dryer.
W
If there is no dryer, install the flow rate sensor downstream of the condensate separator and
suitable filters.
Do not install the Durchflusssensor directly behind a regulator/filter regulator. Only use
the specified sensor/filter combination.
Assembly options
W
Assembly with mounting clip (W05)
W
Assembly with block assembly kit (W03)

Connecting the compressed air
O
Comply with the limits for pressure and temperature (see "13 Technical Data").
O
Observe the flow direction when connecting the device (input left, output right).
1. Install the Durchflusssensor observing the flow direction and connect the Durchflusssensor
to the maintenance unit or to the block assembly kit appropriate for the line (see
5/2
and ).
2. Assemble the device combination or the Durchflusssensor with a block assembly kit or a
mounting bracket. Make sure that fitted elements are properly sealed.
3. Next, apply pressure to the section of tubing and check for possible leaks and any functional
defects.
Electrical installation
Damage to the device or unexpected operation due to work on the system when under
voltage
Unexpected operation due to work on the system when under voltage can lead to personal
injuries and to damage to the device.
O
Make sure the system is not under pressure or voltage before performing the following
tasks:
– Wiring work
– Connecting and disconnecting electrical connections
O
Observe the applicable safety regulations when working on electrical systems!
O
Only reconnect the supply voltage for the device after completing all connection work and
carefully inspecting the wiring work.
Damage to the device due to incorrect supply voltage
Incorrect supply voltage can lead to damage to the device.
O
Only operate the device with protected low voltage and safe electrical isolation in
accordance with protection class III.
Note on routing data lines
O
Use shielded data lines with twisted pairs.
O
Implement a correct and complete shielding concept.
O
Always route and wire lines in accordance with EMC regulations to avoid
interference, e.g. from switching power supplies, motors, timed regulators, and
contactors.
O
Do not route lines in cable conduits in parallel with power supply lines and motor
lines over a long distance.
CAUTION

WARNING
CAUTION
Protection class IP67 and/or IP69 for the device is only achieved if the following
conditions are met:
W
The line plugged onto the M12 connection is screwed down.
W
The cover is screwed down (no gap between the upper cover and the upper housing).
W
If these conditions are not met, the device does not comply with any specified IP protection
class.
Connecting the flow rate sensor electrically
The Durchflusssensor has a 5-pin or 8-pin M12x1 connection on the top (see
7
) for the power supply and outputs.
O
Only operate the Durchflusssensor via a power pack with safe isolation from the
power supply (PELV in acc. with DIN VDE 0100-410, IEC 60364-4-41,
HD 60364.4.41, EN 60079-14). The power circuit must be potential-free (not
grounded).
O
Use AVENTICS connecting cables (series CON-RD - M12x1) to connect the
Durchflusssensor.
O
Carefully assemble the CON-RD - M12x1 round plug connector to ensure the IP67 protection
class.
If the connection is not used, it has to be covered with a suitable cap in order to maintain the
IP65 protection class of the housing.
O
Observe the pin assignments (see Tab. 1 and
O
The flow rate sensor (IO-Link) has two switch outputs or one IO-Link communication or two
analog outputs. The switch outputs at contact points 5 and 4 can be used as NO, NC types and
wired accordingly, see "13 Technical Data".
O
Use shielded cables if the Durchflusssensor is exposed to strong electromagnetic fields.
O
For extension cables with open ends, make sure that bare wire ends do not touch each
other (danger of short circuit when supply voltage is switched on!).
O
Insulate the wires against each other accordingly.
O
Protect the device with a separate fuse at the beginning of the supplying power circuit.

To electrically connect the Durchflusssensor:
O
Attach the M12x1 plug of the CON-RD connecting cable to the connection on the flow rate

sensor ( ).
After the supply voltage is switched on and the readiness delay has passed (approx. 1 s), the
device is in the run mode (normal operation).
Connect the line according to its function. After applying the supply voltage, the display shows
the current measured value.
