Error codes – Recommended
action
Condensed state message active, when prompted, Err appears.
When fault alarms exist, they are displayed here.
73 Internal device error 1 Internal device error
Status classification [Maintenance required]
Recommended action Return positioner to SAMSON for repair.
74 FF parameters Error in parameters not critical to control operation.
Status classification [Maintenance required]
Recommended action Confirm error. Check and, if necessary, change the settings of the re-
quired parameters.
75 Info parameters Error in information parameters not critical to closed-loop control oper-
ation.
Status classification [Maintenance required]
Recommended action Confirm error. Check and, if necessary, change the settings of the re-
quired parameters.
76 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 this case, the positioner
changes to the fail-safe position ( SAFE ) when a measuring error occurs.
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 voltage
has been applied, it carries out a self-test ( tEStinG runs across the dis-
play).
If the positioner loads the wrong program, the valve moves to the fail-
safe position ( SAFE ). It is not possible to make the valve leave this fail-
safe position again.
Status classification Maintenance alarm (cannot be classified)
Recommended action Interrupt current signal and restart the positioner. If not successful, return
positioner to SAMSON for repair.
