Installed.
Umit adjustment settings regulate the points at

The door will stop in the up direction if anything
interferes with door travel. The door will reverse in
the down direction ifanything interferes with the
door travel (including binding or unbalanced doom).
To operate the opener, press the Wall Control push
bar. Run the opener through a complete travel
cycle.

If your door passes both of these tests, no limit
