Abstract:
1. A barrier operating system having a diagnostic performance feature, comprising: a barrier movable between limit positions; a counterbalance system coupled to said barrier; a motor coupled to one of said counterbalance system and said barrier to assist in movement of said barrier; a position detection device coupled to one of said barrier, said counterbalance system and said motor, wherein said position detection device generates a barrier position signal, and wherein one of said motor and said position detection device generates operational parameter values for said barrier moving in either direction; a controller receiving and storing said operational parameter values and said barrier position signal; and a diagnostic input connected to said controller, wherein initiation of said diagnostic input changes the barrier operator system from an operational mode to a diagnostic mode during which said barrier is moved and said controller compares operational parameter values for each direction of movement at a given position of barrier movement, and generates a diagnostic signal based upon the comparison.
