No emergency mode
The travel measuring system of the positioner has a self-monitoring
function (see Code 62).
An emergency mode (open-loop control) is not available for certain
actuators, such as double-acting actuators. In case of a travel sensing
error, the positioner vents the output (Output 38) or A1 in double-acting
actuators. During the initialization, the positioner automatically checks
whether the actuator has such a function or not.

Recommended action
Merely information, confirm, if necessary.
No further action required.

Software loading
error
When the positioner starts operation for the first time after the PA signal
has been applied, it carries out a self-test (

If the positioner loads the wrong software, the valve moves to the fail-
safe position. It is not possible to make the valve leave this fail-safe
position again.
