The travel measuring system of the positioner has a self-moni-
toring function (see Code 62).
A controlled emergency mode is not available on certain actua-
tors, such as double-acting actuators. For this reason, the
positioner moves into the fail-safe position when a measuring
error occurs. During the initialization, the positioner checks
whether the actuator has such a function or not.
Remedy Merely information, confirm, if necessary.
No further action necessary.
When the device starts operation for the first time after the input
signal has been applied, it carries out a self-test ( tEStinG runs
across the display).
If the device loads a program that does not correspond to that of
the positioner, the valve is moved into the fail-safe position. It is
not possible to make the valve leave this fail-safe position again
by operating the positioner.
Remedy Interrupt current and restart positioner. Otherwise, return the
positioner to SAMSON AG for repair.
Errors in options parameters, e.g. due to EMC disturbances.
Remedy Return the positioner to SAMSON AG for repair.
