MAINTENANCE
General:
The LVCN-90 series level transmitter itself requires no periodic
maintenance except cleaning as required. It is the responsibility of the
user to determine the appropriate maintenance schedule, based on the
specific characteristics of the application liquids.
Cleaning Procedure:
1. Power: Make Sure that all power to the transmitter, controller
and/or power supply is completely disconnected.
2. Sensor Removal: In all through-wall installations, make sure that
the tank is drained well below the sensor prior to removal.
Carefully, remove the sensor from the installation.
3. Cleaning the Sensor: Use a soft bristle brush and mild detergent,
carefully wash the transducer of the LVCN-90. Do not use harsh
abrasives such as steel wool or sandpaper, which might damage
the transmitter's surface. Do not use incompatible solvents which
may damage the PVDF transducer or the transmitter’s PP body.
4. Sensor Installation: Follow the appropriate steps of installation as
outlined in the installation section of this manual.
