WARNING! Port X pressurization with D2 controller!
Port X of D2 controllers is a measuring portonly. External pressurization leads to an
impermissible pressure increase and can cause serious injury or death, or can cause
damage to the axial piston unit.
▶ Make sure that no external pressure is applied at portX.
