摘要：
A balance control system comprises a motor (30), a transmission system providing connection between the motor (30) and the door (24) and adapted to move the door (24) between a closed position and an open position located above the closed position, a counterbalance system (60) to reduce power required to lift the door (24), an apparatus to generate first signal representing a force used to move the door (24) from the closed position to the open position, and to generate a second signal representing a force used to move the door (24) from the open position to the closed position, and a controller (70) responsive to the first signal and to the second signal to indicate an imbalance of the door (24) when a difference between the first signal and the second signal exceeds a predetermined threshold.
