• Check the product functions.
9.2 Cleaning
9.2.1 General requirements
Cleaning intervals
• The system owner specifies the cleaning intervals in line with the ambient
conditions at the operating site.
Aids
• Only clean the product with damp cloths.
• Only use water for cleaning and a mild detergent, if necessary.
9.2.2 Procedure
1. Close all openings with suitable safety devices so that no cleaning agent can
enter into the system.
2. Remove all dust deposits from the product and the adjacent system parts.
3. If necessary, remove other production-related deposits from the product and
the adjacent system parts.
9.3 Maintenance
In normal ambient conditions, the product is maintenance-free.
9.4 After service
If no damage has been detected and the operator has not reported any malfunc-
tions, the product can be reconnected to the power supply and put back into op-
eration.
10 Disassembly and exchange
Disassembly is only required if the product has to be exchanged, installed in a dif-
ferent location or disposed off.
10.1 Basic requirements
10.2 Preparation
1. Close off dangerous areas.
2. Make sure the system or system part is not under pressure or voltage.
DANGER! Slowly exhaust the system to avoid uncontrolled movements of the
system components.
3. Protect the system against being restarted.
4. Allow product and adjacent system parts to cool down.
5. Wear PPE.
6. Loosen and remove all connections.
7. Remove the flow sensor from the pressure connection using an open-end
wrench (thread connection) or pull it straight out of the push-in fitting.
11 Disposal
Improper disposal will lead to pollution of the environment. Furthermore, the
materials can no longer be recycled.
Dispose of the product, the packaging and any escaping operating materials
u
in accordance with the applicable national regulations.
12 Troubleshooting
12.1 Procedure
Step 1: Check the system
In case of malfunctions, first check the system or the system part where the
u
product is installed. Check the following items:
• All connections
• Settings. See g 13. Technical
AVENTICS™ AF2 | R412026496–BAL–001–AC | English
data.
Step 2: Check the product
1. Make sure the system or system part is not under pressure or voltage.
2. Check the product based on the fault patterns described below.
3. Perform troubleshooting using the information under "Remedy".
If the malfunction cannot be eliminated as described under "Remedy": Disas-
semble the product and return it. See
4. After the malfunction has been eliminated; Put the system or product back
into operation.

Message Description
Simulation active Simulation active (output sig-
nal or process variable).
Flow low Info Info: MBE -5 %.

Remedy
• There is a problem in the
MQTT configuration:
Check if broker, port or au-
thentication are invalid.
• There is a problem in the
Ethernet configuration:
Check network settings.
• Reduce the load on the
switch outputs.
• Ensure that specified val-
ues for ambient tempera-
ture are maintained.
Eliminate short circuit.
Eliminate short circuit.
• Check whether line is
properly connected.
• Check whether load resis-
tance is too high.
• Ideal: load of 500 Ω
• Check whether ambient
temperature is too high.
• Reduce pulse width.
• Increase pulse value.
