Abstract:
1. In an operator for a barrier moveable between open and closed positions, said operator including a motor, a control unit for controlling operation of said motor, a sensor for sensing a parameter which corresponds to a force exerted by said barrier when moving between open and closed positions, a motor control circuit for controlling operation of said motor, a controller in communication with said motor control circuit and said sensor and a user interface operably connected to said controller including user controllable means for setting a first force limit to be exerted by said barrier when moving in one direction between said open and closed positions, the method including the steps: operating said user interface by a user of said operator to set a user selected first force limit to be exerted by said barrier when moving between said open and closed positions in said one direction; and causing said controller to automatically set a second force limit to be exerted by said barrier when moving in the opposite direction after operating said user interface to set said first force limit.
