Test The Safety Reversal System; Important Safety Check - CHAMBERLAIN Power Drive 3132E FS2 Manual Del Propietário

ADJUSTMENT STEP 3

Test the Safety Reversal System

Garage Door Installation
TEST
• With the door fully open, place a 38 mm obstacle on
the floor, centered under the garage door.
• Operate the door in the down direction. The door
must reverse on striking the obstruction.
ADJUST
• 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.
NOTE: 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 27.
• Repeat the test.
• When the door reverses on the 38 mm obstacle,
remove the obstruction and run the opener through 3
or 4 complete travel cycles to test adjustment.

IMPORTANT SAFETY CHECK:

Repeat Adjustment Steps 1, 2 and 3 after:
• Each adjustment of door arm length, limits, or force
controls.
• Any repair to or adjustment of the garage door
(including springs and hardware).
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.
Gate Installation
TEST
The opener must reverse if the gate comes in contact
with an obstruction. A closing gate should reverse with
little effort, and open completely. See Adjustment
Step 2.
• Use 38 mm board laid flat against the wall or gate
edge.
• SLIDING GATE DOOR, place a 38 mm board
between the door and wall of a closing gate. Gate
must reverse on the board and open completely.
Repeat at opposite wall if two openers are installed.
• SWING OUT GATE, insert a 38 mm board between
the closing gate sections. Gate sections must reverse
and swing open completely.
ADJUST
•
If the gate stops on the obstruction, it is not traveling
far enough in the closing direction. Increase the
DOWN limit adjustment screw counterclockwise 1/4
turn. Repeat test.
• When the gate reverses on a 38 mm board, remove
the obstruction and run the opener through complete
travel cycle to test adjustment.
If the gate will not reverse after repeated adjustment
attempts, call for professional gate service.
WARNING
Without a properly installed safety reversal system,
persons (particularly small children) could be
CAUTION
SERIOUSLY INJURED or KILLED by a closing door or
gate.
• Safety reversal system MUST be tested every month.
• If one control (force or travel limits) is adjusted, the
other control may also need adjustment.
• After ANY adjustments are made, the safety reversal
system MUST be tested. Door MUST reverse on
contact with 38 mm obstacle on the floor. Gate MUST
reverse on contact with 38 mm obstacle at the closing
edge.
