Abstract

A method includes opening an access member of a sensing assembly to access programming features of the sensing assembly. Operating instructions for the sensing assembly are selected, and then a teaching actuator is actuated. The method further includes indicating the teaching actuator has been actuated, such as by visually indicating with an LED, and ceasing the indication. The method further includes implementing the operating instructions if the teaching actuator is released within a predetermined time period from cessation of the indication.
