Note: Approximately every 24 hours, the GT20 Control will perform a UL required motor test. This test only
happens during a normal activation cycle that has been initiated by a user. Once a day, after the door
has been activated, the door will fully open then time out and begin to close normally. While the door is
closing, about ½ way through the cycle, the control will bring the door to an abrupt stop for about three
seconds then it will continue to allow the door to close. As previously stated this is a normal procedure
required by UL and is completed once a day by the GT20.
