Qa Menu
This menu contains the settings for the analog output.
Assigning measurement parameters to the current output
O
Go to the Mode submenu to assign measurement parameters, such as flow, temperature, or
pressure, to the current output.
Assigning the full scale value (MBE)
O
Go to the High submenu and set the full scale value to 20 mA.
Assigning the measurement range start value
O
Go to the Low submenu and set the measurement range start value to 4 mA.
Setting the inversion of the current output
O
Go to the Polarity submenu to set if the current output should be inverted.
Setting the current output behavior in case of a device failure
O
Go to the Fail submenu to set if the behavior of the current output if a failure occurs.
Setting a predefined current value
O
Go to the Simulate submenu to set a predefined current value.

Commissioning and Operation
If no entry is made for longer than 2 minutes, the display will return to display mode.
Unconfirmed settings will not be taken over.
Before commissioning the system, the following steps must have been carried out and
completed:
W
You have fully mounted and connected the Durchflusssensor, in accordance with the
installation conditions (see also "5 Assembly").
W
You have carried out the required pre-settings and configuration.
Dangerous system operating states from incorrect settings on the flow rate sensor or if the
maximum/minimum flow rate sensor operating voltage is exceeded
Danger of injury and system damage from uncontrolled system operating states.
O
Do not make any improper changes to the Durchflusssensor during operation. Note that
the any settings become immediately effective when they are confirmed!
O
Exchange faulty flow rate sensors immediately!
O
Do not disconnect the Durchflusssensor from the voltage source during operation!
To commission the flow rate sensor:
1. Apply the operating voltage.
2. Pressurize the system component the Durchflusssensor is connected to.
3. The sensor performs a self-test and is then ready for use. The measured value menu is
displayed.
For problems during commissioning, see "11 Error and Warning Messages".
The Durchflusssensor does not have a main switch. Once you have connected the device
to the power pack and this has been connected to the mains, the Durchflusssensor is
turned on and ready for use. To turn it off, simply disconnect the power pack from the
power supply.
Short commissioning (with factory setting)
Short commissioning can be used for applications under reference conditions, see "Installation
Conditions".
Note for the IO-Link version:
If digital outputs Q1 and Q2 are used as IO-Link, frequency, or pulse output,
simultaneously with analog outputs Qa and Q2, the precision of the analog outputs may
be impaired.

Service and Repairs
The flow rate sensor is maintenance-free.
Only use water and, if necessary, a mild cleaning agent for cleaning.
Information on filter maintenance can be found in the filter instructions R412013436 (Filter AS1/
AS2/AS3/AS5).
10 Disassembly
System is under high pressure
Danger of injury and system damage from uncontrolled system operating states.
O
Make sure that the system component the Durchflusssensor is installed in is not under
pressure or voltage before beginning disassembly.
1. Make sure that the system is not under voltage or pressure.
2. Loosen and remove all connections.
3. Loosen the flow rate sensor from the pressure connection using an open end wrench (thread
connection) or pull the Durchflusssensor straight out of the push-in fitting.
