OPERATION TESTING THE AUTOMATIC REVERSAL SYSTEM See Figure 80. DANGER: Test the automatic reversal system every month and after any adjustments are made to the garage door travel limits. If the door contacts an object higher than 1-1/2 in. off the garage floor (approx. the size of a 2x4 laid flat), it should stop and reverse to the fully open position. If the automatic reversal system does not function properly, a closing garage door could kill or seriously injure someone in its path. WARNING: DO NOT operate the garage door opener unless the automatic reversal system is working correctly. Following this rule will reduce the risk of death or serious personal injury. Press and release the UP/DOWN button on the indoor keypad to raise the garage door. Place a 1-1/2 in. board (approx. the size of a 2x4 laid flat) on the garage floor beneath the door. Press and release the UP/DOWN button on the indoor keypad to lower the garage door. When the door strikes the board, it should reverse direction immediately. NOTE: After the door contacts the board, a buzzer will sound five times and the garage door opener's LED lights blink five times. If the garage door reverses direction after contacting the board, the reversal system is working properly and no adjustments are needed. If the garage door stops before striking the board or strikes the board and then stops, increase the travel limit for the closed position and repeat the test. If the automatic reversal system continues to fail, contact customer service or a qualified service person for assistance. Up/Down Button 2 x 4 45 - English Fig. 80
