INSTALLATION STEP 6

Install the Door Control

Locate door control within sight of the door at a minimum height of 5 feet (1.5 m) where small children cannot reach, and away from moving parts of the door and door hardware. The installation surface must be smooth and flat. If installing into drywall (Figure 1), drill 5/32" holes and use anchors provided. For pre-wired installations (as in new home construction), it may be mounted to a single gang box (Figure 2).

NOTE: After installation, a green indicator light behind the cover will indicate proper connection. If not lit, the Lock and Light features will not function (reverse wires to correct).

1. Strip 7/16" (11 mm) of insulation from one end of bell wire and connect to the two screw terminals on back of door control by color: white wire to 2 and white/red wire to the 1 (Figure 3).

2. Remove white cover by gently prying at slot in top of the cover with a small flat head screwdriver. Fasten with 6ABx1-1/4"self-tapping screws (drywall installation) or 6-32x1" machine screws (into gang box) as follows:

• Drill and install bottom screw, allowing 1/8" (3 mm)

to protrude above wall surface.

• Position bottom of door control on screw head and

slide down to secure. Adjust screw for snug fit.

• Install top screw with care to avoid cracking plastic

housing. Do not overtighten.

• Insert top tabs and snap on cover.

NOTE: The push bar may stick if the door control is not mounted on a smooth surface. If a click is not heard when pressing the push bar, loosen the two mounting screws or relocate the door control to a smoother surface.

3. (Standard installation only) Run bell wire up wall and across ceiling to motor unit. Use insulated staples to secure wire in several places. Do not pierce wire with a staple, creating a short or open circuit.

4. Strip 7/16" (11 mm) of insulation from end of bell wire. Connect bell wire to the quick-connect terminals as follows: white to white and white/red to red.

NOTE: When connecting multiple door controls to the opener, twist same color wires together. Insert wires into quick-connect holes: white to white and red/white to red.

5. Use tacks or staples to permanently attach entrapment warning label to wall near door control, and manual release/safety reverse test label in a prominent location on inside of garage door.

NOTE: DO NOT connect the power and operate the opener at this time. The trolley will travel to the full open position but will not return to the close position until the sensor beam is connected and properly aligned. See Safety Reversing Sensor Instructions beginning on page 15.

To prevent possible SERIOUS INJURY or DEATH from electrocution:

• Be sure power is not connected BEFORE installing door control.

• Connect ONLY to 24 VOLT low voltage wires.

To prevent possible SERIOUS INJURY or DEATH from a closing garage door:

• Install door control within sight of garage door, out of reach of children at a minimum height of 5 feet (1.5 m), and away from all moving parts of door.

• NEVER permit children to operate or play with door control push buttons or remote control transmitters.

• Activate door ONLY when it can be seen clearly, is properly adjusted, and there are no obstructions to door travel.

• ALWAYS keep garage door in sight until completely closed. NEVER permit anyone to cross path of closing garage door.

INSTALLATION STEP 9

Electrical Requirements

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.

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:

• Remove the motor unit cover screws and set the cover aside.

• Remove the attached 3-prong cord.

• 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.

• Reinstall the cover.

To avoid installation difficulties, do not run the opener at this time.

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.

INSTALLATION STEP 10

Install The Protector System

The safety reversing sensor must be connected and aligned correctly before the garage door opener will move in the down direction.

IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSOR

When properly connected and aligned, the sensor will detect an obstacle in the path of its electronic beam. The sending eye (with an amber indicator light) transmits an invisible light beam to the receiving eye (with a green indicator light). If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to full open position, and the opener lights will flash 10 times.

The units must be installed inside the garage so that the sending and receiving eyes face each other across the door, no more than 6" (15 cm) above the floor. Either can be installed on the left or right of the door as long as the sun never shines directly into the receiving eye lens.

The mounting brackets are designed to clip onto the track of sectional garage doors without additional hardware.

If it is necessary to mount the units on the wall, the brackets must be securely fastened to a solid surface such as the wall framing. Extension brackets (see accessories) are available if needed. If installing in masonry construction, add a piece of wood at each location to avoid drilling extra holes in masonry if repositioning is necessary.

The invisible light beam path must be unobstructed. No part of the garage door (or door tracks, springs, hinges, rollers or other hardware) may interrupt the beam while the door is closing.

• Be sure power is not connected to the garage door opener BEFORE installing the safety reversing sensor.

• To prevent SERIOUS INJURY or DEATH from a closing garage door:

– Correctly connect and align the safety reversing

sensor. This required safety device MUST NOT be disabled.

– Install the safety reversing sensor so beam is NO

HIGHER than 6" (15 cm) above garage floor.

• Slip the curved arms over the rounded edge of each door track, with the curved arms facing the door. Snap into place against the side of the track. It should lie flush, with the lip hugging the back edge of the track, as shown in Figure 1.

If your door track will not support the bracket securely, wall installation is recommended.

Wall installation:

• Place the bracket against the wall with curved arms facing the door. Be sure there is enough clearance for the sensor beam to be unobstructed.

• If additional depth is needed, an extension bracket or wood blocks can be used.

• Use bracket mounting holes as a template to locate and drill (2) 3/16" diameter pilot holes on the wall at each side of the door, no higher than 6" (15 cm) above the floor.

• Attach brackets to wall with lag screws.

• If using extension brackets or wood blocks, adjust right and left assemblies to the same distance out from the mounting surface. Make sure all door hardware obstructions are cleared.

Floor installation:

• Use wood blocks or extension brackets to elevate sensor brackets so the lenses will be no higher than 6" (15 cm) above the floor.

• Carefully measure and place right and left assemblies at the same distance out from the wall. Be sure all door hardware obstructions are cleared.

• Fasten to the floor with concrete anchors as shown.

MOUNTING AND WIRING THE SAFETY SENSORS

• Slide a 1/4"-20x1/2" carriage bolt head into the slot on each sensor. Use wing nuts to fasten sensors to brackets, with lenses pointing toward each other across the door. Be sure the lens is not obstructed by a bracket extension (Figure 4).

• Finger tighten the wing nuts.

• Run the wires from both sensors to the opener. Use insulated staples to secure wire to wall and ceiling.

• Strip 7/16" (11 mm) of insulation from each set of wires. Separate white and white/black wires sufficiently to connect to the opener quick-connect terminals. Twist like colored wires together. Insert wires into quick-connect holes: white to white and white/black to grey (Figure 5).

ALIGNING THE SAFETY SENSORS

• Plug in the opener. The indicator lights in both the

sending and receiving eyes will glow steadily if wiring connections and alignment are correct.

The sending eye amber indicator light will glow regardless of alignment or obstruction. If the green indicator light in the receiving eye is off, dim, or flickering (and the invisible light beam path is not obstructed), alignment is required.

• Loosen the sending eye wing nut and readjust, aiming directly at the receiving eye. Lock in place.

• Loosen the receiving eye wing nut and adjust sensor until it receives the sender’s beam. When the green indicator light glows steadily, tighten the wing nut.

TROUBLESHOOTING THE SAFETY SENSORS

1. If the sending eye indicator light does not glow steadily after installation, check for:

• Electric power to the opener.

• A short in the white or white/black wires. These can occur at staples, or at opener connections.

• Incorrect wiring between sensors and opener.

• A broken wire.

2. If the sending eye indicator light glows steadily but the receiving eye indicator light doesn't:

• Check alignment.

• Check for an open wire to the receiving eye.

3. If the receiving eye indicator light is dim, realign either sensor.

NOTE: When the invisible beam path is obstructed or misaligned while the door is closing, the door will reverse. If the door is already open, it will not close. The opener lights will blink 10 times. (If bulbs are not installed, 10 clicks can be heard.) See page 15 .

Fiberglass, aluminum or lightweight steel garage doors WILL REQUIRE reinforcement BEFORE installation of door bracket. Contact your door manufacturer for reinforcement kit.

WARNING

INSTALLATION STEP 11

Fasten the Door Bracket

Follow instructions which apply to your door type as illustrated below or on the following page.

A horizontal reinforcement brace should be long enough to be secured to two or three vertical supports. A vertical reinforcement brace should cover the height of the top panel.

Figure 1 shows one piece of angle iron as the horizontal brace. For the vertical brace, 2 pieces of angle iron are used to create a U-shaped support. The best solution is to check with your garage door manufacturer for an opener installation door reinforcement kit.

NOTE: Many door reinforcement kits provide for direct attachment of the clevis pin and door arm. In this case you will not need the door bracket; proceed to Step 12.

SECTIONAL DOORS

1. Center the door bracket on the previously marked vertical centerline used for the header bracket installation. Note correct UP placement, as stamped inside the bracket.

2. Position the top edge of the bracket 2"-4" (5-10 cm) below the top edge of the door, OR directly below any structural support across the top of the door.

3. Mark, drill holes and install as follows, depending on your door’s construction:

Metal or light weight doors using a vertical angle iron brace between the door panel support and the door bracket:

• Drill 3/16" fastening holes. Secure the door bracket using the two 1/4"-14x5/8" self-threading screws. (Figure 2A)

• Alternately, use two 5/16" bolts, lock washers and nuts (not provided). (Figure 2B)

Metal, insulated or light weight factory reinforced doors:

• Drill 3/16" fastening holes. Secure the door bracket using the self-threading screws. (Figure 3)

Wood Doors:

• Use top and bottom or side to side door bracket holes. Drill 5/16" holes through the door and secure bracket with 5/16"x2" carriage bolts, lock washers and nuts (not provided). (Figure 4)

NOTE: The 1/4"-14x5/8" self-threading screws are not intended for use on wood doors.

INSTALLATION STEP 12

Connect Door Arm to Trolley

SECTIONAL DOORS ONLY

• Make sure garage door is fully closed. Pull the emergency release handle to disconnect the outer trolley from the inner trolley. Slide the outer trolley back (away from the door) about 2" (5 cm) as shown in Figures 1, 2 and 3.

• Figure 1:

– Fasten straight door arm section to outer trolley

with the 5/16"x1" clevis pin. Secure the connection with a ring fastener.

– Fasten curved section to the door bracket in the

same way, using the 5/16"x1-1/4" clevis pin.

• Figure 2:

– Bring arm sections together. Find two pairs of

holes that line up and join sections. Select holes as far apart as possible to increase door arm rigidity.

• Figure 3, Hole alignment alternative:

– If holes in curved arm are above holes in straight

arm, disconnect straight arm. Cut about 6" (15 cm) from the solid end. Reconnect to trolley

with cut end down as shown. – Bring arm sections together. – Find two pairs of holes that line up and join with

bolts, lock washers and nuts.

• Proceed to Adjustment Step 1, page 20. Trolley will re-engage automatically when opener is operated.

ADJUSTMENT STEP 1

Adjust the UP and DOWN Travel Limits

Limit adjustment settings regulate the points at which the door will stop when moving up or down.

To operate the opener, press the Door Control push bar. Run the opener through a complete travel cycle.

• Does the door open and close completely?

• Does the door stay closed and not reverse unintentionally when fully closed?

If your door passes both of these tests, no limit adjustments are necessary unless the reversing test fails (Adjustment Step 3, page 22).

Adjustment procedures are outlined below. Read the procedures carefully before proceeding to Adjustment Step 2. Use a screwdriver to make limit adjustments. Run the opener through a complete

travel cycle after each adjustment.

NOTE: Repeated operation of the opener during adjustment procedures may cause the motor to overheat and shut off. Simply wait 15 minutes and try again.

NOTE: If anything interferes with the door’s upward travel, it will stop. If anything interferes with the door’s downward travel (including binding or unbalanced doors), it will reverse.

HOW AND WHEN TO ADJUST THE LIMITS

• If the door does not open completely but opens at least 5 feet (1.5 m):

Increase up travel. Turn the UP limit adjustment screw clockwise. One turn equals 3" (7.5 cm) of travel.

NOTE: To prevent the trolley from hitting the cover protection bolt, keep a minimum distance of 2-4" (5-10 cm) between the trolley and the bolt.

• If door does not open at least 5 feet (1.5 m):

Adjust the UP (open) force as explained in Adjustment Step 2.

• If the door does not close completely:

Increase down travel. Turn the down limit adjustment screw counterclockwise. One turn equals 3" (7.5 cm) of travel.

If door still won't close completely and the trolley bumps into the pulley bracket (page 4), try lengthening the door arm (page 19) and decreasing the down limit.

• If the opener reverses in fully closed position:

Decrease down travel. Turn the down limit adjustment screw clockwise. One turn equals 3" (7.5 cm) of travel.

• If the door reverses when closing and there is no visible interference to travel cycle:

If the opener lights are flashing, the Safety Reversing Sensors are either not installed, misaligned, or obstructed. See Troubleshooting, page 17.

Test the door for binding: Pull the emergency release handle. Manually open and close the door. If the door is binding or unbalanced, call for a trained door systems technician. If the door is balanced and not binding, adjust the DOWN (close) force. See Adjustment Step 2.

Without a properly installed safety reversal system, persons (particularly small children) could be SERIOUSLY INJURED or KILLED by a closing garage door.

• Incorrect adjustment of garage door travel limits will interfere with proper operation of safety reversal system.

• 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 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on floor.

WARNING

To prevent damage to vehicles, be sure fully open door provides adequate clearance.
