英语翻译
Asterisks in the table below indicate the control position which regulation devices should take up in a situation where the central process control system has failed or communication between control system and that particular device is lost.
In instances where there is an ideal failsafe action,but this action may not be practical due to availability or complexity of suitable equipment,the ideal action is indicated by a '1' and the second more practical action is marked with a '2'.
The table is intended as a guideline only.Each plant,especially a new plant,shall be considered individually as differing process plant configurations may require differing failsafe actions for some regulation devices.
Regulation devices for coal mill circuits are intentionally excluded from this guideline because the large variety of milling circuit make a single universal failsafe guideline impractical.
