VEGASWING 66 • - transistor (NPN/PNP)

You can dismount the sensor for test purposes and check its function
by immersing the vibrating element in the original medium.
Procedure
1. Separate the instrument briefly (>2 s) from voltage supply.
After switching on again, the instrument must take on the same
switching status.
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.
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.
