A small arrow points into the operational direction of the actuator during initial-
ization.
FQM FS ready
After successful initialization, actuator and valve are in the same end position. In the
status line (top), the symbol is displayed,i.e. the constant force spring is wound,
the FQM is ready for fail safe operation. At the same time, the display indicates the
actuator position as figure (default setting %). For valve operation, the actuator is
now ready to operate in standard mode.

Actuator position
Bar chart empty = actuator is in end position CLOSED (0.0 %)
Bar chart black = actuator is in end position OPEN (100 %)
