-As long as no pushbutton is pressed, the directional control valve remains in the
retracted end position.
-The piston rod of the cylinder is to be advanced if either of the two pushbuttons
S1 or S2 is pressed.
The electrical circuit diagram and the pneumatic circuit diagram of a control
system are shown below. Which statements about the mode of action are correct?
two answers are correct
-As long as no pushbutton is pressed, the directional control valve remains in the
retracted end position.
-If one of the two pushbuttons is pressed, the directional control valve remains in
the retracted end position.
-The piston rod of the cylinder is to be advanced only if both pushbuttons S1 and
S2 are pressed.
, -The piston rod is advanced. When one of the two pushbuttons is released, the
directional control valve switches to the normal position. The piston rod is
retracted.
