(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 .

• 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:
