Proof test (WHG, SIL)
To find out possible undetected, dangerous failures, a proof test must
be carried out in adequate time intervals to check the safety function.
It is the user's responsibility to choose the type of testing.
You will find further instructions in the Safety Manual.
The following options are available for carrying out the proof test
(WHG, SIL):
1 Filling the vessel up to the switching point
If this does not cause any problems, you can fill the vessel up to the
switching point and monitor the correct sensor reaction.
2 Dismounting of the sensor and immersion in the original
medium
You can dismount the sensor for test purposes and check its proper
functioning by immersing it in the original product.
