ADJUSTMENT STEP 3

Test the Safety Reversal System

TEST

•With the door fully open, place a 1-1/2" (3.8 cm) board (or a 2x4 laid flat) on the floor, centered under the door.

•Operate the door in the down direction. The door must reverse on striking the obstruction. Upon successful safety reversal test proceed to Adjustment Step 4.

ADJUST

•If the door stops on the obstruction, it is not traveling far enough in the down direction. Complete Adjustment Steps 1 and 2 Programming the Limits and Forces.

•Repeat the test.

•When the door reverses on the 1-1/2" (3.8 cm) board (or 2x4 laid flat), remove the obstruction and run the operator through 3 or 4 complete travel cycles to test adjustment.

•If the unit continues to fail the Safety Reverse Test, call for a trained door systems technician.

IMPORTANT SAFETY CHECK:

Test the Safety Reverse System after:

•Each adjustment of limits, or force controls.

•Any repair to or adjustment of the door (including springs and hardware).

•Any repair to or buckling of the floor.

•Any repair to or adjustment of the operator.

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing door.

•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 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on the floor.

1-1/2" (3.8 cm) board (or a 2x4 laid flat)

ADJUSTMENT STEP 4

Test The Protector System®

•Press the remote control push button to open the door.

•Place the operator 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 operator lights will flash.

The door operator 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).

If the operator closes the door when the safety reversing sensor is obstructed, do not operate the door. Call for a trained door systems technician.

Without a properly installed safety reversing sensor, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing door.
