Error codes – Recommended action Condensed state message active, when prompted, Err appears.
When fault alarms exist, they are displayed here.
75 Info parameters Info parameter errors that are not critical for the control.
Status classification [Maintenance required]
Recommended action Confirm error.
Check and, if necessary, reset required 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
checks whether the actuator has such a function or not.
Status classification [No message]
Recommended action Merely information, confirm, if necessary.
No further action necessary.
77 Program loading error When the positioner starts operation for the first time after the in-
put signal has been applied, it carries out a self-test (
tEStinG runs
across the display).
If the positioner loads the wrong program, the valve moves to the
fail-safe position. 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 and restart positioner.
Otherwise, return the positioner to SAMSON AG for repair.
78 Options parameter
