CAUTION!
Hazards due to improper configuration of protec‐
tive functions
Flexible Limits must not be used for protective func‐
tions, because the monitoring function is not guaran‐
teed beyond an exceeding of 320 %.
It is not possible to monitor temperature values in
Degree Fahrenheit and pressure values in psi.
Although parameters 3631 Ä p. 208
3630 Ä p. 208 are configured to a value display in °F
or psi, flexible limit monitoring always refers to the
value in Degree Celsius or bar.
