#CMT# #/CMT# The controller has a power supply (2), a high frequency (HF) receiver (20), and a motor control (5) provided with a motor (4). A battery (13) provides emergency power supply to the motor control with the motor during power failure. The battery is charged via a charge controller (9) during start-up time of the power supply. A switched controller (56) controls a terminal voltage of the battery. A motor relay (48) includes a contact (50) for controlling the motor control during power failure. A charging condition of the battery is monitored by a controller (16). #CMT# : #/CMT# An independent claim is also included for a method for controlling a door. #CMT#USE : #/CMT# Controller for controlling a door i.e. garage door (claimed). #CMT#ADVANTAGE : #/CMT# The controller controls the door without making power losses in a cost-effective manner, and maintains the emergency power supply without requiring mains operation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of a controller for a door i.e. garage door. 2 : Power supply 4 : Motor 5 : Motor control 9 : Charge controller 13 : Battery 16 : Controller 20 : High frequency receiver 48 : Motor relay 50 : Contact 56 : Switched controller. |
