AT THIS POINT PLUG CONNECT THE POWER TO THE OPERATOR.
Step 17: Check the Setting - Door Close Limit
Confirm trolley close position 9” to 10” between the inside face of the door and |
| 9”to |
|
| |
|
|
|
|
| |
the point where the door arm connects to the trolley (see illustration). If |
|
|
|
|
|
adjustment of the close trolley position is necessary, activate the opener and |
|
|
|
|
|
move the trolley 12” to 18” to provide access to the “Limit Stop” devices |
|
|
|
|
|
(mounted on the chain). Move the limit stop to establish the correct trolley |
|
|
|
|
|
close position as above. Relocation of “Limit Stop” toward the door increases |
|
|
|
|
|
down travel. Relocation of the limit stop away from the door reduces down |
|
|
|
|
|
travel. Note that each chain link provides 1/2” adjustment of trolley travel. |

STEP 18: Photoelectric Obstruction Test
Test Procedure |
|
Place an object 6” x 12” on the floor (as illustrated) |
|
progressively on foot from the left side of the door; center |
|
of the door and one foot from the right side of the door. |
|
The object must prevent an open door from closing in any |
|
other mode other than constant pressure on the wall button. |
|
The object should also cause a closing door stop and |
|
reverse to the open position. If it doesn’t, the Safe Finish |
|
photoelectric system must be adjusted lower and the test |
|
repeated until the door responds properly to the 6” object. |
|
If adjustments are needed, refer to Step 13. |
|
If the unit still will not respond and fails this obstruction | 12” |
sensing beam test, the door may cause severe injury or |
|
Step 19: Important - Test “Opener
Obstruction Sensing Feature”
A.Activate door to the Open position.
B.Place 2” x 4” laid flat on garage floor under path of the door.
See Figure.
C Activate door to close position; upon contacting solid object, the door should stop, then reverse direction within 2 seconds and travel to the full open position.
Note: If the fails to pass this test, review Step 17, above.
