Reaction times and safety characteristics for fail-safe operation
This section applies to fail-safe operation with fail-safe Mobile Panels.
Note
Proof-test intervals
Proof
-test interval of the device (Lifetime): 20 years. The device must be replaced after this,
at the latest.
Proof
-test interval for safety-
related operator controls dependent on the Safety Integrity Level
SIL:
•
SIL2: Function test 1 × per year
•
SIL3: Function test 1 × per month
Reaction times
The table shows below the reaction times of the HMI device up to the output of the
connection box, dependent on the F-system.
● For hardwired F-system: Reaction time of HMI device up to output or interface X10 of the
connection box.
● For a PROFIsafe-based F-system: Reaction time of HMI device up to interface X1 of the
connection box.
