What to Do in Case of a Fault

In case of a fault, use the following checklist to determine whether a fault with the vibration
monitoring can be remedied.
If none of the information provided in the checklist solves the problem, you can contact Pep-
perl+Fuchs via your sales office with any queries. Have details of the model number and firm-
ware version of the sensor ready if possible.

Cause
No supply voltage
Interruption in the connec-
tion cable
Faulty fuse
Reversed polarity in the
connection
Vibration sensor not
mounted correctly
Vibration sensor mounted
in the wrong position
Remedy
Check the voltage supply and/or supply lines.
Replace the connection cable.
Replace the fuse in the voltage supply area of
the sensor.
Check the voltage supply and ensure the polarity
is correct.
Check that the sensor is mounted correctly.
Ensure that the sensor thread is tightened with a
tightening torque of 8 Nm.
The vibration behavior can vary depending on
the measuring point / mounting point. Therefore,
mount the sensor as precisely as possible at the
point where you want to estimate/monitor the
corresponding vibration behavior.
