Abstract (en)
[origin: DE10012405A1] The comparatively large number of electrical leads required for connection to the switch-cabinet which houses the control modules required for the electrohydraulic drives can lead to the danger of faulty circuits at the assembly and commissioning stage of the equipment. The controller for providing a variable/variables for movement of the hydraulic actuator as well as an electronic circuit for movement sequence of the hydraulic actuator are arranged in the same housing (12) as the position controller for the valve piston.
