Should an error occur in the data range of the positioner, the
self-monitoring function recognizes it and automatically corrects
it.
Remedy Automatic
An error was detected in the data relevant for safety,
autocorrection is not possible. This may be due to EMC distur-
bances.
The control valve moves to its fail-safe position.
Remedy Reset over Code 36.
Re-initialize the positioner.
Determination of the measured value for the actuator has failed.
Conductive plastic element is defective.
The positioner continues to run in emergency mode, but should
be replaced as soon as possible.
The emergency mode on the display is indicated by a blinking
control symbol and 4 dashes instead of the position indication.
Note on the control:
If the measuring system has failed, the positioner is still in a reli-
able state. The positioner switches to emergency mode where the
position cannot be accurately controlled anymore. However, the
positioner continues operation according to its reference variable
signal so that the process remains in a safe state.
Remedy Return the positioner to SAMSON AG for repair.
The reference variable is much smaller than 4 mA (0 %); occurs if
the power source that drives the positioner does not comply with
the standard.
This state is indicated on the positioner display by a blinking
LOW .
Remedy Check reference variable.
If necessary, limit the current source downwards so that no values
below 4 mA can be issued.
