System and related methods for diagnosing operational performance of a motorized barrier operator

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.
