Abstract:
A control system for selectively controlling movement of a device between first and second working positions, the control system comprising:a control actuator selectively actuated to enable fluid communication between the control system and a source of pressurized fluid; a driving system for selectively driving the device between the first and second working positions in response to the control actuator enabling fluid communication between the control system and the source of pressurized fluid; a sensing system for identifying either of the first and second working positions of the device and manipulating a flow of pressurized fluid to the device in response thereto; and a monitoring actuator selectively actuated by the sensing system for relieving the flow of pressurized fluid to a portion of the driving system, wherein the monitoring actuator remains actuated until the control actuator is deactuated.
