object while closing on nudging, the doors will stop and resume closing only
after the obstruction has been removed.

interrupted, the doors will reverse and reopen partially. After the obstruction
is cleared, the doors will begin to close.
G. Door Open Watchdog: If the doors are opening, but do not fully open after a
field adjustable time, the doors will recycle closed then attempt to open six

H. Door Close Watchdog: If the doors are closing, but do not fully close after a
field adjustable time, the doors will recycle open then attempt to close six
times to try and correct the fault.
I. Door Close Assist: When the doors have failed to fully close and are in the
recycle mode, the door drive motor shall have increased torque applied to
possibly overcome mechanical resistance or differential air pressure and
allow the door to close.
