Without a properly installed safety reversal system,
persons (particularly children) could be SERIOUSLY
INJURED or KILLED by a closing the 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 40mm (1 1/2”) high object (or 4x2 laid
flat) on the floor.
Without a properly installed safety reversing sensor,
persons (particularly children) could be SERIOUSLY
INJURED or KILLED by a closing door.
ADJUSTMENT STEP 5
Test the Safety Reversal System
TEST
• With the door fully open, place a 40mm (1 1/2”) board
(or a 4x2 laid flat) on the floor, centered under the 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 40mm (1 1/2”) board (or
4x2 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.
ADJUSTMENT STEP 6
Test The Protector System
®
• Press the remote control push button to open the door.
• Place the operator carton in the path of the door.

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.
