Abstract
The method is for monitoring the movement of a member which is moved along a path which has a vertical component and an arcuate component about a vertical axis. The movement is brought about by a piston movable in a cylinder and having a piston rod projecting therefrom on which the member is mounted. A cam which engages a cam track is mounted on the piston rod or a further piston rod of the piston and acts to cause the arcuate movement. The method comprises mounting a proximity detector on the cam track to sense the piston rod, connecting the proximity detector to a contactless connector so that signals are passed from the mechanism to a transmitter of the connector mounted on the machine frame, and comparing signals received by the transmitter with signals indicating the stage reached in the cycle of operation.
