Abstract
The invention refers to a control device for an actuator (1). The device, controlled by a control valve (20; 71; 80, 81), comprises slides (30, 31) to obtain different conditions of the control valve, and these slides (30, 31) are activated by a two-position fluidics solenoid valve (32, 33) to which a set-point instruction is applied (6). The control device comprises a processor (10) to be assured of the response of the solenoid valve depending on the set-point instruction (6) over the full range that the actuator (1) can cover.
