Attach the Cable Tension Monitor (Required)

NOTE: The cable tension monitor is shipped for left side installation. It is recommended
that the cable tension monitor be installed on the same side of the door as the garage
door opener. For right side installation, remove the snap-ring holding the roller in place
and reassemble it on the opposite side of the cable tension monitor.
1. Make sure the door cable is approximately 3/4" (19 mm) from the mounting surface.
Door adjustments or shimming may be required to achieve proper depth for the door
cable.
2. Position the cable tension monitor as close to the drum as possible. Make sure cable
tension monitor is located over a wood support member and the roller is free from
any obstructions.
NOTE: There must be no obstructions in the installation area that prevent the cable
tension monitor from closing completely when slack is detected.
3. Mark and drill 3/16 inch pilot holes for screws (pilot holes are not required for
anchors).
NOTE: If the cable tension monitor cannot be mounted into wood with the screws
provided, it can be mounted into 1/2 inch (1 cm) or greater drywall using the drywall
anchors (2) and the #8 screws (2) provided in the hardware bag.
4. Attach the cable tension monitor to the wall using the hardware provided. Make sure
that the roller is on top of the cable.
5. Run bell wire to garage door opener. Use insulated staples to secure wire.
6. Connect bell wire to the green quick-connect terminals on the garage door opener
(polarity is not important).
NOTE: Cable must have tension through entire door travel. Make sure there is no
slack in cable on opposite side of garage door during normal operation. If slack
occurs during door travel, adjust cables as required.

The cable tension monitor MUST be
connected and properly installed before
the garage door opener will move in the
down direction.
The cable tension monitor detects ANY
slack that may occur in the cables and
will reverse the door, eliminating service
calls.
