linear actuator
Manipulated variable direction of action
The direction of action (rising or falling) of the display and the position
feedback (Iy) can be set with this.
Tight closing with manipulated variable (see figure 4-9, page 102)
With this function the valve can be driven to the seat with the maximum
actuating force of the actuator (continuous contact of the piezo-valves).
The tight closing function can be activated on one side or for both limit
positions. YCLS becomes active when the setpoint is below the value
set with parameter “YCDO” or above that set with parameter “YCUP”.
