ADJUSTMENT STEP 1
Aligning the DoorSentry® Infrared Safety Beam
WARNING
For safety, pull the trolley release handle
to disengage the trolley from the traveler
slide during these alignment tests.
The DoorSentry consists of two units, an infrared emitter and an
infrared detector. The emitter constantly sends a narrow infrared
beam to the detector. If the door is moving down, and an obstacle
interrupts the beam, the DoorSentry will stop the door and reverse
it causing the door to go up. The operator light will flash three
times, indicating an obstruction has occurred.
If the door is up and there is an obstacle interrupting the
beam, or the DoorSentry is not aligned, the radio transmitter
will not function. The operator will only run the door down if
constant pressure is applied to the wall station pushbutton.
WARNING
Failure to test and adjust safety reverse
system may result in serious injury or
death from a closing garage door. Repeat
this test once a month and adjust as
needed.
Be sure power is applied to the operator.
The green lights on the DoorSentry detector and emitter
should be lit.
If the detector’s red light is off and the green light is on,
the detector is getting power, but it is not “seeing” the
infrared beam from the emitter. Either there is an object
blocking the beam or the emitter and detector are not
properly aligned. Loosen the mounting nuts and re-align
the safety beam while watching the red light (stay out of
the path of the beam while aligning).
Adjust until the red light glows constantly and tighten all
mounting hardware.
☞
NOTE: If detector’s red light remains off, check for the
following: 1) Dirt on detector lens, 2) Sunlight shining on
detector causing interference, 3) Short in wires (from staples
or at screw terminals), 4) Incorrect wiring of detector or
emitter to operator.
With the trolley disengaged, press the wall station
button to run the traveler to the up position.
Push the wall station button again. While the traveler is
moving to the down position, block the infrared light beam.
THE TRAVELER MUST STOP, THEN REVERSE TO THE
UP POSITION. The operator light will flash three times.
Leave an object in the path of the infrared light beam.
Verify that constant pressure on the wall station
pushbutton is required to cause the traveler to move to
the down position. Release the wall station pushbutton
before the traveler stops, verify that the traveler returns to
the up position.
☞
NOTE: The garage door operator will not respond to a
CLOSE command from a radio transmitter if red light on the
detector is off.
