Test The Safety Reverse System; Testing The Safety Infra-Red Safety Sensors - B&D Easylifter Instructions Manual

ADJUSTMENT STEP 3

Test the Safety Reverse System

TEST
• With the door fully open, place a 40mm board on
the floor, centred under the garage door.
• Operate the door in the down direction. The door
must reverse on striking the obstruction.
ADJUST
• If the door stops on the obstruction, it is not
traveling far enough in the down direction.
Increase the DOWN limit by turning the DOWN
limit adjustment screw counterclockwise 1/4 turn.
NOTE: On a sectional door, make sure limit
adjustments do not force the door arm beyond a
straight up and down position. See the illustration
on page 23.
• Repeat the test.
• When the door reverses on the 40mm board,
remove the obstruction and run the opener through
3 or 4 complete travel cycles to test adjustment.
If the door will not reverse on the board after
repeated adjustment attempts, call for professional
B&D garage door service.
IMPORTANT SAFETY CHECK:
Repeat Adjustment Steps 1, 2 and 4 after:
• Each adjustment of door arm length, limits, or
force controls.
• Any repair to or adjustment of the garage door
(including springs and hardware).
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.
ADJUSTMENT STEP 4
Test the Safety Infra-red Reversing
Sensors (if installed)
• Press the remote control push button to open the
door.
• Place the opener carton in the path of the door.
• Press the remote control push button to close the
door. The door will not move more than 25mm,
and the door control will blink 10 times.
The garage door opener will not close from a remote
if the indicator light in either sensor is off (alerting
you to the fact that the sensor is misaligned or
obstructed).
If the opener closes the door when the safety
reversing sensor is obstructed (and the sensors
are no more than 150mm above the floor), call for
professional B&D garage door service.
Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED
or KILLED by a closing garage 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 high object on the floor.
GARA GE DOOR
Without a properly installed safety reversing sensor, persons
(particularly small children) could be SERIOUSLY INJURED or
KILLED by a closing garage door.
The force, as measured on the closing edge ot the door,
should not exceed 400N (40kg). If the closing force is more
than 400N, the Safety Infra-red Reversing Sensor must be
installed. Do not use the force setting procedure to
compensate for a binding or sticking garage door. Excessive
force will interfere with the proper operation of the Safety
Reverse System or damage the garage door.
