ASSEMBLY

Refer to following page for illustrations.

1. Lay out the two pieces of track on the floor, parallel to each other and install the end idler shaft assembly.
2. Install the track hangers with 3/8" hardware. The number of track hangers will vary with the door width. The holes in the track for the track hangers are pre-punched and are generally about 5 feet (1.5 m) apart.
3. Install the take-up bolt on the trolley with two 3/8" hex nuts and lock washers. Slide the trolley onto the track so that the take-up bolt will be facing the operator. NOTE: For bi-parting doors, slide the bi-part trolley into the track assembly first, so the bi-part trolley is closest to the front idler.
4. Install one final track hanger on the back of the operator. Remove the spacer bar which comes assembled in the frame of the operator. Position the track assembly on the operator and reinstall the spacer within the rails, tightening the bolts securely. For a right-to-open single sliding door, the operator should be mounted on the right-hand end of the track with the pulleys facing out. Install two 3/8-16" x 1" hex bolts with lock washers and nuts through the remaining two mounting holes in the operator.
5. Attach the chain to the take-up bolt on the trolley using the master link. Reel the chain around the drive sprocket, up to the idler shaft and then back to the hole on the front of the trolley.
6. Using the two 10-32 x 1-1/4" screws and hardware, attach the chain to the front end of the trolley. It may be necessary to remove some links for proper tension. Tighten the chain by adjusting the take-up bolt. A properly adjusted chain will sag about 3 inches at the midpoint of the track. NOTE: Leave the bi-part trolley free at this time.
7. Bolt the angle mounting brackets to the track hangers through the slots in the angle mounting brackets. Use the 3/8-16" hex head bolts with flat washers under the heads and lock washers and nuts under the track hangers. Do not tighten as the distance from the wall to the track will have to be adjusted later.

⚠️ WARNING

To prevent possible SERIOUS INJURY or DEATH:

• DO NOT connect electric power until instructed to do so.
• If the door lock needs to remain functional, install an interlock switch.
• ALWAYS call a trained door systems technician if door binds, sticks or is out of balance. An unbalanced door may not reverse when required.
• NEVER try to loosen, move or adjust doors, door springs, cable, pulleys, brackets or their hardware, ALL of which are under EXTREME tension and can cause SERIOUS PERSONAL INJURY.
• Disable ALL locks and remove ALL ropes connected to door BEFORE installing and operating door operator to avoid entanglement.
• Fasten the operator SECURELY to structural supports of the building.
• Concrete anchors MUST be used if installing ANY brackets.

INSTALLATION

TYPICAL INSTALLATION

NOTE: Refer to Operator Dimensions in the introduction for general information.

1. Determine the clearance necessary for the door to pass between the operator and the wall. This dimension must be less than 4" (10.16 cm), it may be necessary to shim the angle mounting brackets out from the wall accordingly.
2. With the door fully closed, locate the vertical center-line of the door and mark this line on the wall above the door. Measure 18" (45.7 cm) to the left of this line if the door slides left-to-close or 18" (45.7 cm) to the right of this line if the door slides right-to-close. NOTE: For bi-parting doors, omit this step. The track should extend 3-1/2 feet (1.06 m) beyond the door opening.
3. Set the assembled operator into position and mark the holes for the angle mounting brackets on the wall, as low as possible without interfering with door travel. Drill holes in the wall for mounting. Through-bolts are recommended for this purpose. If wall construction does not permit the use of through-bolts, lag bolts and shields may be used.
4. Secure the assembled operator to the wall. IMPORTANT: BE SURE OPERATOR, TRACK AND DOOR TRACK ARE PARALLEL. Check that the door clears the operator when moving. Adjust the track hangers on the angle mounting brackets to the desired position and tighten all bolts. It is recommended that at least one sway brace be used (not provided) between the wall and one of the track hangers for increased rigidity, especially on large or heavy doors.
5. Mount the door disconnect mechanism on the center-line of the door so that the top of the bracket is no more than 1-1/2" (3.8 cm) below the trolley. This mechanism may be adjusted both front to back and up and down to align the disconnect pin. It may be necessary to shim between the mechanism and the door to bring the disconnect pin out into the center-line of the track. NOTE: For bi-parting doors, mount each door disconnect mechanism centered on a line 24" (61 cm) from the door edge.
6. Move the door so that the disconnect pin is directly aligned with the hole in the trolley and engage the disconnect pin in hole. NOTE: For bi-parting doors, it is necessary to bring the doors to a fully closed position for proper synchronization. With both disconnect pins engaged in their respective trolleys, lift the drive chain over the three studs on the bi-part trolley and secure the chain with the hardware provided.
7. Adjust the screw collars on the disconnect pin so that it enters into the trolley bracket about 3/4" (1.9 cm).
8. Mount the chain retaining bracket (with keyhole slot) at a convenient height on the door, directly below and aligned with the disconnect chain. Mount the chain retaining bracket so that the keyhole is in the horizontal plane (repeat for bi-part door).

❗ CAUTION

To avoid possible SERIOUS INJURY from a falling operator:

• Fasten the operator SECURELY to structural supports of the building.
• Concrete anchors MUST be used if installing ANY brackets into masonry.

Diagram illustrating operator mounting clearances, angle mounting brackets, door disconnect mechanism, screw collar, and chain retaining bracket placement.

• 1" min.
• 1-1/2" min.
• 4" max. operator clearance from wall.
• Angle Mounting Brackets should not interfere with door travel.
• Bottom of Track.
• 6-1/4" max.
• Top of Door.

FUSIBLE LINK (OPTIONAL)

NOTE: Refer to Operator Dimensions in the introduction for general information.

1. Mount chain retaining bracket to door, approximately 4 feet (1.2 m) above the floor and 2" (5.1 cm) off center-line of door.
2. Attach eye bolt to the lower slot on disconnect assembly.
3. Secure fusible link mounting bracket to upper leading edge of door (6 - 12" (15.2 - 30.5 cm) below top of door) so that the fusible link will be in door opening when door is open.
4. Thread the fusible link chain through the eye bolt, then through the eyelet in the weight mechanism, and then up through the bottom of the disconnect pin.
5. Raise the weight to approximately 3' (.9 m) from floor level and engage the chain in the slot of the chain retaining bracket.
6. Couple the chain to itself around the weight so that the chain cannot move through the eyelet in the weight.
7. Disengage the chain and allow the weight to hang from the fusible link.
8. Leave a small amount of slack between the weight and the disconnect pin and fasten a split key ring to the link on each side of the disconnect pin so that the chain cannot pass through the hole.
9. Cut off excess chain, leaving 6" (15.24 cm) to hang below chain retaining bracket.
10. Fasten large split key ring to end of chain.
11. Mount the weight guide to the door with weight protruding above guide 3 - 4" (7.6 - 10.2 cm).
12. For bi-part doors install the second fusible link assembly on the other door in the same manner. Be sure that one is lower than the other so as not to interfere with each other when the doors are fully closed.
13. IMPORTANT: TEST THE FUSIBLE LINK DISCONNECT INSTALLATION AS FOLLOWS: Manually remove the fusible link from the bracket and allow the weight to pull down on the disconnect pin. Verify that the door is disconnected and moves freely. If necessary, adjust spring on disconnect assembly by moving top shaft collar up or down.

4. Re-tighten the set screw that is directly over the flat portion of the shaft.

Diagram showing the torque limiter adjustment nut and set screws on the gear reducer.

AUXILIARY REVERSAL SYSTEM / RPM SENSOR

The Auxiliary Reversal System is designed to protect the door and motorized operator. It is NOT a substitute for an entrapment device.

Feature: This feature utilizes the RPM sensor connected to the logic board to detect when the clutch slips and reverses the door (clutch must be properly adjusted). In addition, the RPM eliminates the need for a centrifugal switch on single phase motors.

Benefit: The Auxiliary Reversal System reverses the operator upon hitting an obstruction, preventing excessive door and operator damage. UL325 requires the use of monitored entrapment protection devices for primary entrapment protection. By removing the centrifugal switch on single phase motors, the leading cause of motor failures is eliminated. (Auxiliary Reversal System not applicable on model GSD.)

NOTE: This feature is automatically learned and does not require programming.

Diagram showing the logic board with RPM sensor and OSE/OPEN indicators.

TESTING

Apply power to the operator. When power is applied to the operator, the following LED's will illuminate: STOP, CLOSE, OPEN, LMEP, 24Vac, RADIO, DATA, TIMER ENABLE, OLS MID, SLS, CLS, and MAS. Once the power up process is completed (approximately 2-3 seconds) only the appropriate LED's will continue to be lit:

• Between limits: 24Vac and STOP
• Fully closed position: 24Vac, STOP, CLS and SLS
• Fully opened position: 24Vac, STOP and OLS

Additional LED's will light when device(s) are activated.

NOTE: When the power up process is over, the MAS LED will blink a code indicating the version of firmware. If the selector dial is in the DIAG, OPTN, or PROG position, the MAS will not provide this code. After the code has been provided the MAS LED will go out.

PROGRAMMING

INTRODUCTION TO PROGRAMMING

Many programmable functions require that a LiftMaster Entrapment Protection (LMEP) device be installed in order to function. Refer to the Entrapment Protection section.

Before programming the logic board, set the operator's open and close limits. LEDs on the logic board are provided to assist setting the limits. As each limit is activated the corresponding LED will light up. The abbreviations are Open Limit Switch (OLS), Close Limit Switch (CLS) and Sensing Limit Switch (SLS). Refer to page 14 for limit switch adjustment instructions.

When power is applied to the operator, the following LED's will illuminate: STOP, CLOSE, OPEN, LMEP, 24Vac, RADIO, DATA, TIMER ENABLE, OLS MID, SLS, CLS, and MAS. Once the power up process is completed (approximately 2-3 seconds) only the appropriate LED's will continue to be lit (i.e., STOP, 24Vdc, limit LED(s) if limit(s) is activated).

NOTE: When the power up process is over, the MAS LED will blink a code indicating the version of firmware. If the selector dial is in the DIAG, OPTN, or PROG position, the MAS will not provide this code. After the code has been provided the MAS LED will go out.

LIFTMASTER MONITORED ENTRAPMENT PROTECTION (LMEP) DEVICE IS REQUIRED

A LiftMaster Entrapment Protection (LMEP) device is required for the following wiring types.

• B2: Momentary contact to open, close and stop, plus wiring for sensing device to reverse and auxiliary devices to open and close with open override. Programmable mid stop available with this wiring type. Compatible with 3-Button Station, 1-Button Station, 1 and 3-Button Remote Control.
• TS (TIMER SECURE): This mode will attempt to close the door from any position except when fully closed, or when a safety input is present. The stop button will not disable the Timer-To-Close at any position. To disable the Timer-To-Close in this mode, installation of a defeat switch is required (see wiring diagram).
• T: Momentary contact to open, close, and stop with open override and Timer-To-Close. Every device that causes door to open, including a reversing device, activates the Timer-To-Close. Auxiliary controls can be connected to open input to activate the Timer-To-Close. If the timer has been activated, the open button and radio control can recycle the timer. The Timer-To-Close will function from the programmable mid stop with this wiring type. Compatible with 3-Button Station, 1-Button Station and 1 and 3-Button Remote Control. NOTE: A Programmable “Car Dealer Mode” available.
• FSTS: Momentary button contact for open, close and stop programming. User set mid stop. User set Timer-To-Close. The single button station opens the door to the full open limit bypassing the mid stop and activates the Timer-To-Close, putting the operator in TS mode until the door reaches the down limit, or is stopped in travel. At which time the operator enters the B2 mode. Compatible with 3-Button Station, 1-Button Station, 1 and 3-Button Remote Control. A 1-Button remote control in FSTS mode will open only with the Timer-To-Close, bypassing a programmed mid stop. The Timer-To-Close will reset and reverse when closing.

LIFTMASTER MONITORED ENTRAPMENT PROTECTION (LMEP) DEVICE IS RECOMMENDED

A LiftMaster Entrapment Protection (LMEP) device is recommended for the following wiring types.

• C2: Momentary contact to open and stop with constant pressure to close, open override plus wiring for sensing device to reverse. Programmable mid stop available with this wiring type. Compatible with 3-Button Station and 1-Button Station.
• E2: Momentary contact to open with override and constant pressure to close. Release of close button will cause door to reverse (roll-back feature) plus wiring for sensing device to reverse. Compatible with 3-Button Station.
• D1: Constant pressure to open and close with wiring for sensing device to stop. Compatible with 2 or 3-Button Station.

Diagram of the Selector Dial showing positions for T, TS, E2, FSTS, D1, C2, B2, DIAG, OPTN, PROG.

IMPORTANT NOTES:

1. External interlocks may be used with all functional modes.
2. Auxiliary devices are any devices that have only dry contacts. Examples: loop detector, pneumatic or electrical treadles, radio controls, one button stations, pull cords, etc.
3. Open override means that the door may be reversed while closing by activating an opening device without the need to use the stop button first.
4. When the door is in a stopped position other than fully closed, and an LMEP or EDGE input is activated, the Restricted Close (RC) feature will allow a close command when the close button is pressed and held. The operator will begin closing after 5 seconds. If the close button is released the door will stop. When in E2 mode, the door will move to the fully open position.
