action
Condensed state message active, when prompted, Err appears.
When fault alarms exist, they are displayed here.
76 No emergency mode The travel measuring system of the positioner has a self-monitoring func-
tion (see Code 62).
An emergency mode (open-loop control) is not available for certain ac-
tuators, such as double-acting actuators. In case of a travel sensing er-
ror, 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.
Status classification [No message]
Recommended action Merely information, confirm, if necessary.
No further action required.
77 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 ( tEStinG runs across the dis-
play).
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 posi-
tion again.
Status classification Maintenance alarm (cannot be classified)
Recommended action Interrupt current signal and restart the positioner.
If not successful, return positioner to SAMSON AG for repair.
