摘要:
A motorized barrier operator that moves a barrier between limit positions, includes a motor for moving the barrier between set limit positions. When the barrier is in a stopped, partially open position the operator implements at least a hybrid control sequence that employs either a four-phase logic or an open-only logic depending upon the status of a mode indicator. In the preferred embodiment the mode indicator is a time light that is activated upon receipt of a user command.
