Output Override
The output of this module is influenced at certain states (see Figure 34).
Figure 34: Output override (COMMON_PID).
When the pressure scenario changes, the selection values (i.e. lower and upper output
limitation Lim- and Lim+) may need to be adjusted!
If a tight-closing function is required, the CutOff function must be parameterized accordingly!
The safety control output as well as, optionally, the System Switch / Flow Switch Override
override both the automatic and the manual control output if enabled!
