If the binary input is activated in automatic mode, the piezo valves are blocked. The
actuator remains at the last position. Leakage measurements can be performed in this
way without using the initialization function.
Using binary inputs 1 or 2, a partial-stroke test can be triggered by actuation of your
choice of a normally closed or normally open switch.
No function
Special function of binary input 1: If binary input 1 is activated in "P-manual mode" by
means of a jumper between terminals 9 and 10, then when the mode button is pushed
the firmware version will be displayed.
