Electrical Requirements; Aligning The Safety Reversing Sensors - Craftsman CMXEOCG322 Owner's Manual

INSTALLATION STEP 13

ELECTRICAL REQUIREMENTS

To prevent possible SERIOUS INJURY or DEATH from
electrocution or fire:
• Be sure power is NOT connected to the opener, and
disconnect power to circuit BEFORE removing cover to
establish permanent wiring connection.
• Garage door installation and wiring MUST be in compliance
with ALL local electrical and building codes.
• NEVER use an extension cord, 2-wire adapter, or change plug
in ANY way to make it fit outlet. Be sure the opener is
grounded.
To avoid installation difficulties, do not run the opener at this time.
To reduce the risk of electric shock, your garage door opener has a
grounding type plug with a third grounding pin. This plug will only fit
into a grounding type outlet. If the plug doesn't fit into the outlet you
have, contact a qualified electrician to install the proper outlet.
RIGHT WRONG
If permanent wiring is required by your local code, refer to the
following procedure. To make a permanent connection through the
7/8" hole in the top of the motor unit (according to local code):
1. Remove the motor unit cover screws and set the cover aside.
2. Remove the attached 3-prong cord.
3. Connect the black (line) wire to the screw on the brass
terminal; the white (neutral) wire to the screw on the silver
terminal; and the ground wire to the green ground screw. The
opener must be grounded.
4. Reinstall the cover.

INSTALLATION STEP 14

ALIGNING THE SAFETY REVERSING SENSORS

The door will not close if the sensors have not been installed and
aligned correctly.
When the light beam is obstructed or misaligned while the door is
closing, the door will reverse. If the door is already open, it will not
close.
1. Check to make sure the LEDs in both sensors are glowing
steadily. The LEDs in both sensors will glow steadily if they
are aligned and wired correctly.
The sensors can be aligned by loosening the wing nuts, aligning the
sensors, and tightening the wing nuts.
Figure 1
If the receiving sensor is in direct sunlight, switch
it with sending sensor so it is on the opposite
side of the door.

Sending sensor - Amber LED
IF THE AMBER LED ON THE SENDING SENSOR IS NOT
GLOWING:
1. Make sure there is power to the garage door opener.
2. Make sure the sensor wire is not shorted/broken.
3. Make sure the sensor has been wired correctly: white wires to
white terminal and white/black wires to grey terminal.
IF THE GREEN LED ON THE RECEIVING SENSOR IS NOT
GLOWING:
1. Make sure the sensor wire is not shorted/broken.
2. Make sure the sensors are aligned.
