Barrier movement operator including timer to close feature
View Patent ↗Methods and apparatus for controlling a barrier movement operator having a timer-to-close feature are disclosed. The methods and apparatus include arrangements for conveniently inhibiting and re-activating the timer-to-close feature and for providing a mid-stop position during movement toward the closed position. Additionally, the embodiments include methods and apparatus for reversing barrier operation.
1. A method for setting a timer-to-close timer value for a barrier movement operator comprising:
signaling, by a user, a desire to set the timer; entering a first timer learn mode in response to the signaling step,
receiving user-activated signals from a first switch where each signal from the first switch specifies a first time interval;
receiving user-activated signals from a second switch where each signal from the second switch specifies a second time interval, different from the first time interval; and
using the time defined by user interaction with both the first and second switches as the timer-to-close timer value.
2. A method for setting a timer-to-close timer value for a barrier movement operator according to claim 1 in which the barrier movement operator comprises a switch unit including an open switch, a close switch and a stop switch and wherein the user activated signals are generated by interaction with one or more of the open, close and stop switches.
3. A method for setting a timer-to-close timer value for a barrier movement operator comprising:
signaling, by a user, a desire to set the timer;
entering a time based learn mode in response to the signaling step;
moving a barrier of the barrier movement operator to an open position;
counting the time while the barrier is in the open position, after the entry of the time based learn mode;
ending the time based learn mode; and
storing an amount of time counted in the counting step for use as the time-to-close timer value.
4. A method for setting a timer-to-close value according to claim 3 comprising detecting that the barrier is in the open position.
5. A method for setting a timer-to-close value according to claim 3 comprising moving a barrier of the barrier movement operator to the open position when the barrier is not at the open position upon entering the time based learn mode.
6. A method for setting a timer-to-close timer value for a barrier movement operator comprising:
signaling, by a user, a desire to set the timer value;
determining in response to a user signaled desire to set the timer value, whether to store a user signaled timer value or a time based timer value;
first identifying a timer value from user-activated signals when the determining step identifies a user signaled timer value;
second identifying a timer value computed from a period of time that a barrier remains in a predetermined position, when the determining step identifies a time based timer value; and
storing a timer value identified by one of the first and second identifying steps in response to the determining step.
7. A method for setting a timer-to-close value according to claim 6 comprising measuring the time that the barrier is in an open position.
8. A method for setting a timer-to-close timer value according to claim 6 comprising receiving signals generated by user actuation of one or more switches.
