IMPORTANT

INSTALLATION INSTRUCTIONS

Do not install this opener or any other opener on "HIGH RISK" garage doors that may cause severe injury, entrapment or death!

See back page for serious injuries which may occur if “HIGH RISK” areas are left uncorrected.

Martin Finger Shield Garage Doors are “Low Risk”.

Untrained or Negligent Installing, Adjusting and Servicing can be Dangerous! The

garage door springs and related parts can cause serious injury or death! IF YOU ARE UNSURE, CALL A TRAINED MARTIN DOOR DEALER!

Garage door should be balanced and easy to open and close by hand.

Locks should be disabled and pull down ropes should be removed.

Locate wall control/push button within sight of door, at min. height of 5' (1520) so

small children cannot reach it, and away from all moving parts of door. See Step 8.

Emergency release tag should be installed above knob and adjusted to about 6' (1830) above the floor.

Risk of electrical shock is explained in Step10. Do not connect opener to source of power until instructed to do so.

Entrapment and warning labels should be installed next to the wall control/push button as explained in Step 14.

IMPORTANT

MAINTENANCE & SAFETY INSTRUCTIONS

Monthly, check the opener's down cycle safety reverse. The door must reverse when it

contacts a 1 1/2" (38) high object (or a 2X4 board laid flat) on the floor, in line with the door opener. A closing door must also reverse if the photo eyes are interrupted. See Steps 12,13.

Always keep the moving door in sight and away from people and objects until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.

NEVER GO UNDER A STOPPED, PARTIALLY OPEN DOOR

Do not allow children to operate or play with the garage door opener controls. Keep all

remote controls away from children.

The emergency release should only be used when garage door is in the closed position. Weak or broken springs may cause door to fall if released in the open position, increasing the risk of severe injury or death. Use caution when using the release with door open.

Monthly visually check the lift cables, spring assembly, hardware, etc. for wear and stability.

If the Safety Reverse or any other part of the garage door and opener system do not work

properly, or if you do not understand, call a trained Martin Door Dealer.

TO REDUCE THE RISK OF SEVERE INJURY OR DEATH, READ AND FOLLOW ALL INSTRUCTIONS

OPENER DOOR BRACKET GUIDELINES

ONLY Martin Finger Shield Garage Door Systems allow you to choose center, off center or side mounting for a safer, more attractive opener installation. See page 2 and 3

WARNING! Other brand doors are designed for center mounted

openers only. Off center or side mounted installations may result in other brand doors binding, side shifting, twisting, and falling, as the lift cables may detach from the cable drums.

A Martin Opener requires 1 1/2" (38) more clearance than the required garage door clearance.

Opener Door Bracket Exception

Martin Doors over 18'2" (5540) wide, high wind Martin Doors and Martin wood doors over 10’2”(3100) wide use 3 1/4”(83) wide “U” struts that fasten over top roller brackets . The opener door bracket fastens on top of this “U” strut, at any location with four 1/4”(6) thread forming screws. With the door in the closed position, f

or low clearance installations, try using straight power arm only for fastening to the opener door bracket. See Figures A,B

asten straight power arm to reversed curved power arm (curve may be cut off). The reversed curved power arm is first fastened to opener door bracket. Fasten power arms together at about a 45° angle for smooth opening and closing of door. F the

INSTALLATION INSTRUCTIONS FOR MARTIN GARAGE DOOR OPENER

SYSTEMS

THESE INSTRUCTIONS ARE INTENDED FOR PROFESSIONAL GARAGE DOOR OPENER INSTALLERS. READ THROUGH THE COMPLETE INSTRUCTION MANUAL AND APPLICABLE SUPPLEMENTAL INSTRUCTIONS BEFORE BEGINNING.

STEP 1

FASTENING THE OPENER DOOR BRACKET

Study "Opener Door Bracket Guidelines” on page 2, 3, and 6.

Decide if the opener will be mounted to the center, off center or side of the garage door. Center

and off center mounted openers always require a “full width” top strut on the door. If side mounted, Martin Doors up to 12'2" (3700) wide may or may not require a top strut.

Fasten the opener door bracket under the top roller bracket for side mounting or on the stile and strut for center/off center mounting. Fasten with 1/4” x 1” Thread Forming Screws. See “Exception” on page 6.

Fasten the curved power arm to the opener door bracket with 3/8" X 1" short neck carriage bolt and two 3/8" lock nuts as shown in the “Opener Door Bracket Guidelines” on page 2 and 3.

Raise the curved opener power arm straight up and touch the torsion tube or spring. Make a vertical mark on header, in line with the power arm. This mark will be the vertically centered location for the opener header bracket. See Figure 1

Note: To hold the top of the curved power arm from falling down, temporarily tie it to the top of

the door bracket or strut. See Figure 1

Make a horizontal mark on the header 2" (51) above the highest movement of the door as it opens. See figure 2.

The following are approximate measurements above the top of a closed door to the horizontal mark on the header:

11 1/2" (292) for 12” (305) regular clearance track.

6 1/2" (165) for 8" (203) low clearance track.

5" (127) for 4 1/4" (108) low clearance track.

3 1/2" (89) for 2 ½" (64) low clearance track.

Fasten the opener header bracket to the header with two 5/16" X 2" lag screws. The vertical

and horizontal marks are the “centered location” marks.

STEP 3

FASTENING THE RAIL ASSEMBLY TO THE POWER HEAD

Place the rail assembly onto the power head chassis by lining up the sprocket assembly

opening with motor shaft. Make sure the shaft engages teeth inside sprocket assembly. Press rail assembly down firmly onto shaft and power head chassis. DO NOT HAMMER!

Fasten 2 "C" brackets over rail assembly and onto chassis. Flanges on "C" brackets must fit into the four recessed areas on chassis. The rail assembly must be at a right angle to the power head for the "C" brackets to fit properly. See Figure 3

Insert 6 X 14 mm chassis screws through "C" bracket holes and into chassis holes, and tighten screws by hand with a phillips screw driver. The “C” brackets must firmly hold rail assembly to chassis. See Figures 3, 4.

Do not remove tape around the trolley and straight power arm until Step 9. The trolley has been taped at the correct location so that the belt or chain position tab will activate the position switch, and opener computer correctly. The activation begins when the opener opens the door, from the closed position, for the first time. See Figure 5

Place power head on stepladder, positioning front of rail assembly on torsion tube (or on torsion spring if side mounted) for stability. See Figure 5

Position rail assembly end-stop within the opener header bracket and insert clevis pin through the end-stop and opener header bracket. Attach the cotter ring to the end of the clevis pin. See Figure 6

PHOTO EYES SAFETY SYSTEM IMPORTANT! CLOSE DOOR BY HAND TO FINISH INSTALLATION!

MOUNTING PHOTO EYES DIRECTLY TO SIDE WALL: Locate mounting position 3" (76) to 5" (127) above the floor. Mark and drill 1/16" (1.5) pilot

hole into wall. (If mounting to concrete or drywall instead of wood, use anchors provided and drill 3/16" (5) pilot hole).

Fasten tapered-head screw into wall. Do not tighten screw. Allow screw head to protrude (approximately 3/8" (9.5)) from wall.

Position the top slot hole on the back of the photo eye holder onto screw and push down to lock in place. See Figure 13

Fasten tapered head screw through the curved channel slot at the bottom of the photo eye holder after drilling correct pilot hole. Repeat process for other photo eye and photo eye holder. See Figure 13

Align photo eyes so they face each other. In Step 12 you will be instructed to check the alignment. Tighten wing nut on each photo eye by hand. See Figure 14

MOUNTING PHOTO EYES TO BRACKET: Locate mounting position 3" (76) to 5" (127) above the floor for photo eye brackets.

Brackets can be mounted in any position as long as photo eye beam has a clear path from one side of door to the other side after mounting. See page 3.

Mark and drill two 1/16" (1.5) pilot holes into wall. (If mounting to concrete or drywall instead of wood, use anchors provided and drill two 3/16" (5) pilot holes).

Using round-head screws provided, fasten bracket to wall. Attach photo eye to bracket by aligning tabs and center pin and snapping into place Photo eye wiring should exit downward. Repeat process for other bracket. See Figures 15 and 16

Align photo eyes so they face each other. In Step 12 you will be instructed to check the alignment. Tighten wing nut on each photo eye by hand. See Figure 16

ATTENTION: In 2-door installations, the "Receiver" photo eyes (as marked on each of

the photo eyes) should be mounted on the far outsides. The "Transmitter" photo eyes should be mounted on the insides, to avoid 2 beams shining into 1 receiver.

See Figure 17

CONNECTING WIRES TO POWER HEAD Route wiring through clip on bottom of photo eye holder, then run wires along wall and ceiling to power head

chassis. Use provided staples to fasten wiring to wall, joists and/or ceiling. Do not pinch wiring.

NOTE: As an alternative, the wiring can be routed along the top of the rail assembly, or along the outside of the

garage door track. Be sure the wiring is routed away from all moving parts of door and rail assembly. (For

Dc3700e with Martin Door applications, see concealed photo-eye wire attachment kit instructions). Open the control panel cover by gently pulling on the 2 tabs, allowing the cover to hang open. To remove, pull carefully on the cover corner near one of the hinges. Do not twist cover or hinges may break. See Figure 23

Route wires through wire guide at top of power head chassis into terminal area of control panel. Separate the dbl. wire from each photo eye into two single wires: 1) the white wire and 2) the black striped wire. See Figure 17

Remove about 1/2" (13) of insulation from the end of each of the four single wires. Twist the white wire ends together and twist the black striped wire ends together. Insert twisted white wire ends firmly into terminal hole #1 by pushing directly into hole. If wires are difficult to insert, a screwdriver may be used to depress the terminal tab while inserting the wires. To remove wiring, depress terminal tab again and pull wiring out. Repeat procedure for the twisted black striped wire ends, except insert them into terminal hole #2.

STEP 8 WALL CONTROL / PUSH BUTTON

The wall control/push button will allow you to control your garage door from inside the garage. It must be mounted within sight of the garage door, clear of all moving garage door parts or any associated parts, at least 5’ (1520) above the floor, out of children's reach. The wall control/push button should only be used when the door area is free of people or any obstructions.

FASTENING THE WALL CONTROL: Attach wiring to back of wall control. White wire end attaches to terminal #3 screw; black striped wire end

attaches to terminal #4 screw.

Locate where top mounting screw will go. Mark location on wall. Drill 1/16" (1.5) pilot hole into wall. Fasten top screw into wall with screw head out from wall about 1/8” (3). Fasten wall control into top slot hole by pushing down firmly onto screw head. For drywall, concrete, etc., drill 3/16” (5) pilot hole for anchors. See Figure 18

Mark and drill 1/16"(1.5) pilot hole through bottom screw hole. Insert screw through bottom hole from the front, and tighten screw. Route wiring from behind through one of the recessed cutouts. Avoid pinching the wires.

CONNECTING WIRES: Route wiring through cutout, along wall and ceiling, to opener power head chassis. Use provided staples to secure

wiring. Do not pinch wiring.

Route wiring through wire guide of chassis to terminal area of control panel. See Figure 17

Remove about 1/2" (13) of insulation from the end of each wire. Insert white wire end firmly into terminal hole #3.

Insert black striped wire end into terminal #4. To remove wiring, depress tab and pull out wiring. Multiple wall controls may be installed, parallel or series, if wires are properly connected to terminals 3 and 4 as explained.

STEP 11

CONNECT OPENER TO POWER CORD AND PLUG

To reduce the risk of electric shock, your opener is provided with an insulated power cord with a 3-prong grounding plug. The power cord permits easy connection to and disconnection from an electrical outlet. The power cord must be plugged-in to a standard grounded outlet. If there is no outlet available at the location, you must have a qualified electrician install an approved-grounded outlet at the proper location.

WARNING! To help prevent electrocution or fire, etc., the installation and wiring and outlet must be done in accordance with local electrical and building codes. DO NOT use an extension cord. DO NOT use a 3-prong to 2-prong plug adapter. DO NOT modify or cut off the grounding pin on the plug.

Plug the power cord into a properly grounded outlet. The#8 LED on the opener control panel will illuminate, showing that the power is on. See Figure 23

OPTIONAL PERMANENT WIRING: (If required by your local electrical code) WARNING! Contact a qualified electrician to run the necessary wiring to your

opener and to perform the electrical connections.

Disconnect the power at the circuit breaker.

Remove the Power Head Housing. Unsnap the power cord strain relief cover by

disengaging the tabs. Cut the power cord within 6" (152) of the terminal block. Replace the strain relief cover by snapping tabs back into place. Knock out conduit hole, and bring in the permanent wiring and conduit. Secure conduit to chassis. Attach wiring using suitable wire nuts (not provided). Reinstall power head housing.

Connect power at the breaker. The #8 LED on the opener control panel will illuminate, showing that the power is on. See Figure 22

MARTIN “SMART COMPUTER” CONTROL PANEL

Open control panel cover by gently pulling on the 2 tabs. Do not twist cover or

hinges may break. See Figure 23

The 3 Control Panel Buttons are labeled "P", "+", and "-”. The circular display contains 4 numbered LED’s. See Figure 24

***STEP 11 CONTINUED***

SETTING THE ADJUSTMENTS Before beginning, confirm that the garage door is the closed position, the trolley is

connected to the chain or belt connector, and the #4 LED is illuminated showing that the power is on.

The adjustments made are Open Travel Limit, Close Travel Limit, the first Transmitter Programming, and if necessary the Opening Force and Closing Force.

REFER TO THE FOLLOWING TO PROGRAM OR CHANGE THE PROGRAM OF THE MARTIN “SMART COMPUTER”:

TO PROGRAM Press and hold the "P" button for about 5 seconds. When all LEDs illuminate release the

button. See Figure 25

OPEN TRAVEL LIMIT LED #1 should be blinking. Press and hold the "+" until the door is in the opened

position. Release this button. If the door is not in the desired position, press the "+" button or the "-" button to move it slightly. Once the door is in the desired position, press and release the "P" button. See Figure 26

CLOSE TRAVEL LIMIT LED #2 should be blinking. Press and hold the "-” button until the door is in the closed

position. Release the button. If the door is not in desired position, press the "+" or the "-" button to move it slightly. Once the door is in the desired position, press and release the "P" button. See Figure 27

Attention! Do not close door tight on floor.

FIRST TRANSMITTER PROGRAMMING LED #3 should be blinking. While LED #3 is blinking, press and hold the desired button on

the transmitter. When the LED #3 blinks rapidly, release the transmitter button. The opener has now learned the particular code of this transmitter. Press and release the "P" button. This stores the code in memory. See Figure 28 For additional transmitter programming see Figures 39, 39A, 39B.

END PROGRAMMING After the LED fade out in a circular pattern the LED #4 should be illuminated. Press transmitter button to open and close the door two times. This allows the opener smart computer to set its complete memory and "learn" the proper operating levels. Each time the door is opened or closed the #3 LED illuminates about 1 second as the belt or chain tab activates the reference switch on the power head chassis. This is a visual check regarding computer memory retention. The “smart computer” retains memory even after a power outage. See Figure 29 next page.

NOTE: If one setting needs to be changed without adjusting any of the other settings,

simply press and hold the "P" button for about 5 seconds, then press and release "P" repeatedly until the desired setting is reached. This bypasses the unneeded adjustments.

IMPORTANT MAINTENANCE & SAFETY INSTRUCTIONS

Monthly, check the opener's down cycle safety reverse. The door must reverse when it

contacts a 1 1/2" (38) high object (or a 2X4 board laid flat) on the floor, in line with the door opener. A closing door must also reverse if the photo eyes are interrupted. See Steps 12,13.

Always keep the moving door in sight and away from people and objects until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.

NEVER go under a stopped, partially open door.

Do not allow children to operate or play with the garage door controls. Keep the remote

control away from children.

SAVE THESE IMPORTANT INSTRUCTIONSSAVE THESE IMPORTANT INSTRUCTIONS

If the Safety Reverse or any other part of the garage door and opener system do not work properly, or if you do not understand, call a trained Martin Door Dealer.

The emergency release should only be used when garage door is in the closed position.

Weak or broken springs may cause door to fall, if released in the open position, increasing the risk of severe injury or death. Use caution when using the release with door open.

Monthly visually check lift cables, spring assembly, hardware, etc. for wear and stability.

KEEP GARAGE DOOR PROPERLY BALANCED. See garage door owner’s manual. An

improperly balanced door increases the risk of severe injury or death. Call a trained Martin Door Dealer to repair lift cables, spring assemblies and other hardware.

STEP 12

TEST DOWN FORCE REVERSAL

Place a 1 1/2”(38) high object (or a 2X4 laid flat) on the floor, in

line with the door opener. When the closing door contacts the object, it should stop, reverse, and automatically return to the open position. If the door does not reverse, reset the down travel limit so that the door travels slightly further down in the closed direction. Then, retest the unit as described above. See Figure 32. Open and close door twice before beginning test. NOTE: Rail assembly may require center support to ceiling.

WARNING! If the door does not reverse, disconnect your opener and call a trained Martin Door Dealer.

TEST DOWN CYCLE PHOTO EYES REVERSAL Photo eyes must be clean and properly aligned. Loosen wing nuts

to rotate photo eyes vertically or horizontally for correct alignment. See Figure 33.

The green light on the transmitter photo eye and the red light on the receiver photo eye must illuminate or the door will not close. See Figure 34

Start the door in the downward direction. Interrupt the invisible beam by waving a solid object between the photo eyes. The Door Must Reverse! See Figure 35

Faulty photo eyes can be bypassed with constant pressure on a wall control/push button or transmitter button.

NOTE: To test the Up Force, place an object to stop the door in its upward direction.

The opener should stop when the door contacts the object. The Martin Opener also has a third reversal protection system, which automatically opens the door in 30 seconds if Opener Reversal System fails or if the door is unable to completely close in 30 seconds time.

TRANSMITTERS

THE BATTERY: Pry transmitter apart using a small coin to expose battery. The 3 Volt #CR2032 battery is

shown. Battery life can last 4 to 5 years. See Figure 36.

TRANSMITTER MOUNTING CHOICES: Transmitter can be carried alone, attached to a key chain, attached to the visor clip or

attached using the optional mounting plate. See Figures 36, 37, 38.

MULTIPLE TRANSMITTERS: Each transmitter has been factory programmed with different private security codes. For

your information there are 284 trillion different codes. 2-channel transmitters have 2 different codes. 4-channel transmitters have 4 different codes. Additional transmitters that come with the opener or are purchased separately as accessories have their own different codes that must be changed to match your first transmitter.

Connect the programming tine to both transmitters. See Figures 38, 39, 39A and 39B.

Press and hold button on your present transmitter. Indicator light will blink. See Figure

39A. While still holding the 1st transmitter button, press and hold the button on the new or second transmitter. Code transfer will occur in approximately 2 seconds when the indicator light on the new transmitter illuminates continuously. See Figure 39B

The 315 mhz transmitters are “Home Link” compatible. Follow instructions furnished in the automobile owners manual for non-rolling code applications.

TRANSMITTER OPERATION: Press button until garage door begins to move. The indicator light on the transmitter will

be blinking. Press button at any time during travel to stop the garage door. See Figure 40

ANTENNA:

The optional 315 mhz antenna wire on the back of the opener is about 13”(340)

long and can have multiple arrangements for the best distance. In a "normal installation" the distance from the transmitter to the power head should be 50' (15000) to 150' (45000). Do not lengthen or shorten the antenna. See Figures 41, 42.

NOTE: The distance from the transmitter to the opener power head may be reduced by

electrical interference in the area, spherical disturbances in the area, various lights or transformers in and out of the garage, automatic sprinkler system timers, various audible or inaudible sounds, noise, radio signals in the area, concrete, steel or lead in and around the garage, antenna wire touching any metal. If necessary, use plastic or string type ties to keep antenna wire away from punched angle, etc.

STEP 16 WALL CONTROL/PUSH BUTTON OPERATION

The wall control button will illuminate when the wires are properly connected as explained in Step 8.

Press wall control/push button until garage door begins to move. Press button at any time during travel to stop the garage door. See Figure 43.

The vacation lock-out feature on the wall control is used to lock out all remote control transmitters. The wall control button or keyless entry system can still activate the door. Press and hold vacation lock button for 2-3 seconds to activate lock-out. The wall control button will blink continuously while lock mode is active. To unlock, press and hold vacation lock button for 2-3 seconds. The wall control button will then return to normal illumination. See Figure 43

NOTE: The opener will accept multiple wall controls/push buttons if the wires are properly

connected as explained in STEP 8.

OPENER LIGHTS OPERATION: Lights will illuminate for about 4 minutes whenever opener is activated. Lights will blink if

the opener senses an obstruction. To stop lights from blinking, remove obstruction and operate door normally.

Lights can be turned on and off by manually pushing light switch button on the wall control. Lights turned on manually can only be turned off by manually pushing light switch button or by opening and closing the door. See Figure 43.

BELT OR CHAIN AIL ASSEMBLY TENSION ADJUSTMENT

Your pre-assembled Belt or Chain Assembly comes from the factory with the tension adjusted to factory specifications. There should be no need for adjustment.

CHECKING TENSION: Release trolley from belt or chain connector. The tension nut/washer should be spaced

approximately 1/16" (1.5) from the stationary end-stop arch at the header end of the rail assembly. See Figure 45.

ADJUST THE TENSION: Increase tension by tightening tension nut clockwise.

Decrease tension by loosening tension nut

counterclockwise.

TO SHORTEN BELT OR CHAIN RAIL ASSEMBLY UP TO 24” (610): (See exploded view of rail assemblies on Page 21)

Note: For trained Martin Garage Door Dealers: Consult factory if cut-off is more than 24”

(610) because the position tab must be kept in the proper location.

Loosen belt or chain tension as much as possible.

Remove screws from sprocket holder and rail end-stop.

Slide belt or chain and all rail assembly parts out of rail assembly from header end.

Measure and cut off excess rail assembly (1” (25) increments only) from header end.

Disassemble connector assembly to expose free ends of belt or chain.

Use the same measurement as the excess rail assembly length and cut the same

amount off both free ends of the belt or chain.

Use rail assembly end-stop as a guide, mark and drill two 3/16" holes on rail assembly sides for rail assembly end-stop screws.

Fasten both ends of the belt ribs or the chain links to the connector assembly.

Slide all rail assembly parts into rail assembly from header end according to

original assembly.

Tension the belt or chain following STEP 17.
