The actuator stem moves to the end positions earlier if the end position guiding function is
active.
9.4.1 Operatingdirectionincreasing/increasing
− Endpositionguiding(stemretracts)(c35): The actuator stem moves the valve to the top
end position if the input signal reaches the value entered in this code. Setting c35 =
100.0% causes this function with a retracting actuator stem to be deactivated.
− Endpositionguiding(stemextends)(c36): The actuator stem moves the valve to the
lower end position if the input signal reaches the value entered in this code. Setting c36
= 0.0% causes this function with an extending actuator stem to be deactivated.
