When fault alarms exist, they are displayed here.
Determination of the measured data 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
closed-loop operation icon and 4 dashes instead of the position
indication.
Note on the closed-loop operation:
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.
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.
The circuit of the i/p converter has been interrupted.
Return the positioner to SAMSON AG for repair.
