Abstract
A control device is provided for use with a pneumatic pump for generating output pressure, a pressure sensor for indicating the level of the output pressure, and an input device for receiving a target pressure level input by a user. The control device is configured to monitor the sensed output pressure during a pressurizing condition in which the pump provides increasing output pressure. The control device is further configured to maintain the pressurizing condition while the level of the sensed output pressure increases past the target pressure level, and to terminate the pressurizing condition in response to the sensed output pressure increasing to a level that exceeds the target pressure level by a predetermined differential value.
