Abstract:
1. A barrier operator comprising: a current limit portion coupled to a mains supply supplying electrical current, the mains supply having a predetermined maximum current limit for the barrier operator; a barrier operator portion coupled to the current limit portion and the mains supply, the barrier operator portion configured to actuate a movable barrier; wherein the current limit portion is configured to selectively apply and remove amounts of the electrical current supplied by the mains supply to the barrier operator and to at least two ancillary devices connected to the current limit portion via at least one outlet so that the electrical current does not exceed the predetermined maximum current limit, wherein the current limit portion is configured to remove amounts of electrical current from the at least two ancillary devices in response to allowing operation of the barrier operator portion without information regarding at least one of the at least two ancillary devices whenever operation of the barrier operator is required to actuate the movable barrier; wherein the current limit portion is configured to selectively apply amounts of electrical current to the at least two ancillary devices by phasing in the at least two ancillary devices in response to allowing operation of the barrier operator portion without exceeding the predetermined maximum current limit.
