Abstract
A barrier operating system having a diagnostic performance feature includes a motorized barrier movable between limit positions and a counterbalance system coupled to the barrier. A disconnect mechanism may be interposed between the motor and the counterbalance system so that the barrier can be moved manually without assistance from the motor. A position detection device is coupled to either the barrier or the counterbalance system and generates a barrier position signal. One of the motor and the position detection device generates operational parameter values for the barrier moving in either direction. A controller receives the operational parameter values and the barrier position signal, and as the barrier is manually moved, the controller compares operational parameter values for each direction of movement at a given position and generates a diagnostic signal based upon the comparison.
