If the binary input is activated, the actuator uses the value defined by "YA" and "YE" for
controlling in the "Automatic" mode.
In "Automatic" operating mode the piezo valves are blocked when the binary input is
activated. The actuator remains in the last position. Leakage measurements can then be
taken without the initialization function.
Binary inputs 1 or 2 can be used to initiate a partial stroke test by pressing either a
normally closed or a normally open contact depending on the choice.
