TIMER TO CLOSE OPTION
The operator is equipped with a timer to close option for use with control devices, such as a
radio control or card key control. The AUTO RE-CLOSE TIMER adjustment screw is located on
the printed circuit board. The operator is shipped from the factory with this timer preset to
the OFF position, fully counter-clockwise. As the timer adjustment screw is rotated clockwise,
the closing of the gate can be delayed from 2 seconds to 60 seconds.
