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):
Electronics directly evaluated via the analogue input of a control system
