Test The Protector System; Test The Safety Reversing Sensor - Chamberlain SECURITY+ 6200 Owner's Manual

Adjustment Step 3

Test The Protector System

• Press the remote control push button to open the
door.
• Place the opener carton in the path of the door.
• Press the remote control push button to close the
door. The door will not move more than an inch,
and the opener lights will flash for 5 seconds.
Professional service is required if the opener
closes the door when the safety reversing
sensor is obstructed.
The garage door opener will not close from a
remote if the indicator light in either sensor is
off (alerting you to the fact that the sensor is
misaligned or obstructed).
Step 3 Test Safety Reverse System SEARS 315-699 (Yellow Disk #2)
The garage door can be closed by pressing and
holding the Door Control push bar until down travel
is completed.
Adjustment Step 4
Test the Safety Reverse System
Test:
• Place a one-inch board (or a 2x4 laid flat) on the
floor, centered under the garage door.
• Operate the door in the down direction. The door
must reverse on striking the obstruction.
Adjustment:
If the door stops on the obstruction, it is not traveling
far enough in the down direction.
• Increase the DOWN limit by turning the DOWN
limit adjustment screw counterclockwise 1/4 turn.
• Repeat the test.
On a sectional door, make sure limit
adjustments do not force the door arm beyond a
straight up and down position. See the
illustration on
page 26.
• When the door reverses on the one-inch board,
remove the obstruction and run the opener through
3 or 4 complete travel cycles to test adjustment.
If the door will not reverse after repeated
adjustment attempts, call for professional
garage door service.
