Proof Test

This section describes a possible proof test procedure. The user is not obliged to use
this proposal. The user may consider different concepts with an individual determination
of the respective effectiveness, e. g. concepts according to NA106:2018.
According to IEC/EN 61508-2 a recurring proof test shall be undertaken to reveal potential
dangerous failures that are not detected otherwise.
Check the function of the subsystem at periodic intervals depending on the applied PFD
in accordance with the characteristic safety values. See chapter 3.4.
It is under the responsibility of the plant operator to define the type of proof test and the interval
time period.
Check the settings after the configuration by suitable tests.
Equipment required:
Use a digital multimeter (without special accuracy) as ohmmeter (mid range
recommended) to check the relay contact outputs. Closed contacts are shown with 0 
(low impedance). Open contacts are shown with OL (overload/high impedance).
Power supply set to nominal voltage of 24 V DC
