20NOTE: Confirm that the door has stopped in the UP position as aresult of the Upper Limit Switch and not because the Trolley has hitthe open Stop Bolt, which is mounted in the Rail near the powerhead. The correct condition can be verified by observing that theopeners Convenience Light does not flash after the fully open doorcomes to a stop. The faulty condition may also be confirmed visu-ally by checking to see if the Trolley is resting against the stop bolt.To confirm final OPEN travel adjustment, activate the opener to bringdoor to fully open position. The opener light should not be flashing.Step 29: Infrared Safety Sensor Obstruction TestTest ProcedureStarting with the door in the fully open posi-tion, place a 6” high object on the floor pro-gressively one foot from the left side of thedoor; center of door and one foot from theright side of door (as illustrated). In eachposition, activation of the opener with thewall station should cause the door to moveapproximately one foot, stop and thenreverse to fully open position. The same 6”high object when placed on the floor shouldalso cause a closing door to reverse.If the door does not respond properly to these tests, the Infrared Safety Sensors must be adjusted (refer to step 21 or 22depending on type of sensors used). Repeat this test procedure. If the door opener still will not respond properly and failsthis test, the door may cause severe injury or death. Have a qualified service person make repairs.Step 30: Programming Wireless Keyless Entry (If Included)NOTE: To facilitate installation, program the Keyless Entry station to the opener before mounting to wall.WARNING: During programming the garage door may operate.
