4-76 Parameter Adjustments & Application Considerations
Note: The order of priority is as follows: Manual MV > MV at stop > MV at
PV error.
MV at PV Error
You can configure the amount the MV is output during an input error
condition. The MV at stop takes priority when stopped and the manual MV
takes priority in manual mode.
Note: The order of priority is as follows: Manual MV > MV at stop > MV at
PV error.
The order of priority of the MVs is illustrated in the following diagram.
