7. Diagnostic, asset management and service
7.1 Maintenance
If the device is used for the purpose for which it is designed ii normal conditions, no maintenance work is
required.
For some applications material accumulations may occur on the antenna system and affect the measurement
result. Depending on the sensor and application, you should therefore take precautions to prevent the antenna
system becoming excessively dirty. The antenna system should be cleaned at certain intervals if necessary.
7.2 Asset management function
The device has a self-monitoring and diagnostic system which complies with NE 107 and VDI/VDE 2650.
Detailed error messages can be viewed in the "
Diagnostic
" menu point using the display and control module
for the status messages shown in the tables below.
Status messages
The status messages are divided into the following categories:
•
Failure
•
Function check
•
Out of specification
•

Failure
The device will output a fault message if it detects a malfunction.
This status message will be active at all times. The user is unable to deactivate it.
Function check
Work is being carried out on the device, the measurement value is temporarily invalid (for example during a
simulation). The default status of this status message is inactive.
Out of specification
The measurement value is uncertain since the device specification has been exceeded (for example
electronic system temperature). The default status of this status message is inactive.
Maintenance
Extreme influences have restricted the function of the device.
The measurement is affected but the measurement value is still valid. Schedule maintenance on the device
since you should expect it to fail in the foreseeable future (for example due to material accumulations).
The default status of this status message is inactive.
