The system has an adjustment screw acting on a membrane of a pressure regulator for performing an initial calibration adjustment at a threshold pressure. An electronic circuit receives a pressure signal provided by a sensor. The circuit receives a signal representing a speed of a pneumatic adjustment unit that makes a dynamic modification of calibration adjustment value. The regulator is controlled by an equipment that permits to pneumatically vary threshold pressure from a separate control module. The equipment is formed of a pneumatic drive module (11) and an electronic board (9). An independent claim is also included for a method for controlling a driven pantograph that is actuated by a pneumatic cushion. |
