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
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.
Statusclassication [No message]
Recommended action Merelyinformation,conrm,ifnecessary.
No further action required.
77 Software loading
error
WhenthepositionerstartsoperationforthersttimeafterthePAsignal
has been applied, it carries out a self-test (tEStinG runs across the
display).
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.
Statusclassication

Recommended action
Interrupt current signal and restart the positioner.
If not successful, return positioner to SAMSON for repair.
