4 Service and troubleshooting
The 973 SmartRadar LT does not require preventive maintenance.
For mechanical and electrical installation details, refer to the installation guides of the Antennas and the
SmartRadar LT
Depending on the application, the Antenna may over time become too contaminated for accurate level
measurement. This condition is then signalled by the built-in diagnostics of the 973 SmartRadar LT. Then a
warning code (WC: 07001) is generated. In that case, the Antenna should be cleaned.
