•
Center each sensor unit in a "C" wrap with lenses pointing
toward each other across the door.
• Secure sensors with the hardware shown in Figure 6. Finger
tighten the wing nut on the
receiving eye
to allow for final
adjustment. Securely tighten the
sending eye
wing nut.
•
Run wires from both sensors to the opener as shown in Figure 6.
Use insulated staples to secure the wire to the wall and ceiling.
• Connect both sets of wires to the opener terminals as shown.
•
Plug in the opener. If your opener has the Multi-Function Door
Control, make sure the Lock Feature is
off
.
Red indicator lights in
both the sending and receiving eyes will
glow
if wiring
connections and alignment are correct.
If the indicator lights are
blinking
(and the invisible light beam path
is not obstructed), alignment is required.
• Loosen the receiving eye wing nut to allow slight rotation of unit.
Adjust sensor vertically and/or horizontally until the red indicator
light
glows
.
• When indicator lights are glowing in both units, tighten the wing
nut in the receiving eye unit.
FIGURE 6
• Press the remote control push button to open the door.
• Place an object large enough to obstruct the sensor beam in the
path of the door.
• Press the remote control push button to close the door.
The
door will not move more than an inch (25mm).
The garage door opener will not close from a remote control if
the indicator light in either sensor is
blinking
(alerting you to
the fact that the sensor is misaligned or obstructed).
You can operate the garage door opener by disconnecting the
safety reversing sensor.
Professional service is required if the opener closes the door
when the Protector System™ is obstructed.
TEST THE PROTECTOR SYSTEM™
TEST THE SAFETY REVERSE SYSTEM
TEST:
• Place a one-inch (25mm) obstacle laid flat on the floor, centered
under the garage door.
• Operate the door in the down direction. The door
must
reverse
on striking the obstruction.
ADJUSTMENT:
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.
• Repeat the test.
On a sectional door, make sure limit adjustments do not force
the door arm beyond a straight up and down position.
• When the door reverses on the one-inch (25mm) obstacle,
remove the obstruction and run the opener through 3 or 4
complete travel cycles to test adjustment.
If the door will not reverse after repeated adjustment
attempts, call for professional door service.
Failure to test and adjust the 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.
TROUBLE SHOOTING
1. If the
sending eye
or
receiving eye
indicator light does not
glow after installation, check for:
• Electric power to the opener.
• A short in the black/white wires. These can occur under
staples or at screw terminal connections.
• Incorrect wiring between sensors and opener.
• An open wire, (wire break).
• Lock switch on Multi-Function Door Control Panel is
activated. Deactivate.
2. If both sensors are blinking, realign or remove obstruction.
3. If an infrared sensor has been installed, it can not be removed
later on. The unit only operates with the IR sensor (starting
September 2004).
4. If the IR sensors are damaged and cannot be repaired, the
door, nevertheless, can be closed using the wall switch
