A reset valve is located in a hydraulic fluid return passageway that is connected between other end of the setting piston and the source of hydraulic fluid. The reset valve can move to selectively block the flow of the hydraulic fluid or allow hydraulic fluid to flow through the fluid return passageway, so that the setting piston can move the setting piston back to its start position.

Abstract: Systems and methods for activating a down hole tool in a wellbore. A trigger is moveably positioned in the interior of a base pipe and includes a first end and a second, smaller end. The trigger is moveable between an unactivated position where a port in the base pipe is blocked and an activated position where the port is open. At least one latch member prevents movement of the trigger from the unactivated position to the activated position until a predetermined force is applied to the trigger. Increasing pressure in the interior increases a force differential between the first end and the second end. When the force differential is substantially equal to the predetermined force, the latch releases and allows the trigger to move from the unactivated position to the activated position, thereby opening the port to permit activation of the down hole tool.
