FAILSAFE Mode
FAILSAFE mode cannot be selected from any of the previous menus.
FAILSAFE mode and display are initiated by detection of a critical fault in the
positioner or the valve system. There are two ways to deal with a FAILSAFE
condition: correct the problem and clear the error messages or run through
the FAILSAFE menu, view error messages, enter MANUAL mode and
RESET. "RESET" restarts operation.
When failsafe occurs:
1. Press + to move to VIEW ERR.
2. Then press * to view the first error message.
3. Pressing + scrolls through all the fault messages in turn.
4. When the cause of the problem has been corrected, press + to
move to CLR ERR.
5. Press * to remove all error messages from memory.
6. Then move to MANUAL menu. If you have cleared the errors
"RESET" will no longer exist.
