Separate the instrument briefly (>2 s) from voltage supply or push
the test key.
Check the results of the test.
Make sure the connected downstream devices are activated dur-
ing the function test.
2. Set the mode switch (min./max.)
Check if the switching status changes (signal lamp - switching
status). By doing so, you can check the function of the measuring
system.
If this is not the case, then there is a fault in the measuring sys-
tem.
Make sure the connected downstream devices are activated dur-
ing the function test.
3. Dismount the instrument and immerse the vibrating element up to
the switching point in the original medium.
Check if the switching status changes (signal lamp - switching
status). By doing so, you can check the function of the measuring
system.
If this is not the case, then there is a fault in the measuring sys-
tem.
Make sure the connected downstream devices are activated dur-
ing the function test.
You can find the coverage of the test in the Safety Manual.
If this does not cause any problems, you can fill the vessel up to the
switching point and monitor the correct sensor reaction.
Procedure
1. Carry out the function test according to the above description (1
Short interruption of the supply line to the sensor.
Separate the instrument briefly (>2 s) from voltage supply or push
the test key.
Check the results of the test.
Make sure the connected downstream devices are activated dur-
ing the function test.
2. Set the mode switch (min./max.)
Check if the switching status changes (signal lamp - switching
status). By doing so, you can check the function of the measuring
system.
If this is not the case, then there is a fault in the measuring sys-
tem.
Make sure the connected downstream devices are activated dur-
ing the function test.
3. Fill the vessel up to the switching point.
Check if the switching status changes (signal lamp - switching
status). By doing so, you can check the function of the measuring
system.
