Gate systems are comprised of many component parts. The gate operator is only one component. Each gate system is specifically designed for an individual application. 2. Gate operating system designers, installers and users must take into account the possible hazards associated with each individual application. Improperly designed, installed or maintained systems can create risks for the user as well as the bystander. Gate systems design and installation must reduce public exposure to potential hazards. 3. A gate operator can create high levels of force in its function as a component part of a gate system. Therefore, safety features must be incorporated into every design. Specific safety features include: - Edges Sensors (contact) - Photoelectric Sensors - Vertical Posts - Instructional and Precautionary Signage 4. Install the gate operator only when: a. The operator is appropriate for the construction and the usage class of the gate. b. All exposed pinch points are eliminated or guarded, and guarding is supplied for exposed rollers. 5. The operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied with a separate access opening. The pedestrian access opening shall be designed to promote pedestrian usage. Locate the gate such that persons will not come in contact with the vehicular gate during the entire path of travel of the vehicular gate. 6. The gate must be installed in a location so that enough clearance is supplied between the gate and adjacent structures when opening and closing to reduce the risk of entrapment. Swinging gates shall not open into public access areas. 7. The gate must be properly installed and work freely in both directions prior to the installation of the gate operator. 8. Permanently mounted access controls intended for users to activate, must be located at least 6 feet (1.8 m) away from any moving part of the gate and where the user is prevented from reaching over, under, around or through the gate to operate the controls. Outdoor or easily accessible controls shall have a security feature to prevent unauthorized use. Exception: Emergency access controls only accessible by authorized personnel (e.g. fire, police) may be placed at any location in the line-of-sight of the gate. 9. The Stop and/or Reset (if provided separately) must be located in the line-of-sight of the gate. Activation of the reset control shall not cause the operator to start. 10. A minimum of two (2) WARNING SIGNS shall be installed in the area of the gate. Each placard is to be visible by persons located on the side of the gate on which the placard is installed. 11. For a gate operator utilizing a non-contact sensor: a. Reference owner’s manual regarding placement of non-contact sensor for each type of application. See Install Entrapment Protection section. b. Care shall be exercised to reduce the risk of nuisance tripping, such as when a vehicle trips the sensor while the gate is still moving. c. One or more non-contact sensors shall be located where the risk of entrapment or obstruction exists, such as the perimeter reachable by a moving gate or barrier. 12. For a gate operator utilizing a contact sensor such as an edge sensor: a. One or more contact sensors shall be located where the risk of entrapment or obstruction exists. b. A hard wired contact sensor shall be located and its wiring arranged so the communication between the sensor and the gate operator is not subject to mechanical damage. c. A wireless device such as one that transmits radio frequency (RF) signals to the gate operator for entrapment protection functions shall be located where the transmission of the signals are not obstructed or impeded by building structures, natural landscaping or similar obstruction. A wireless device shall function under the intended end-use conditions. d. One or more contact sensors shall be located on the inside and outside leading edge of a swing gate. Additionally, if the bottom edge of a swing gate is greater than 4 inches (10.1 cm) but less than 16 inches (406 mm) above the ground at any point in its arc of travel, one or more contact sensors shall be located on the bottom edge. 4 ## Page 5 # SAFETY ## Gate Construction Information Vehicular gates should be installed in accordance with ASTM F2200: Standard Specification for Automated Vehicular Gate Construction.

If adjusting the length, ensure that both sections of the arm are adjusted proportionally. Use the set screws on the arm to temporarily hold the arm in place while determining the correct measurements. 1. Close the gate and measure the distance of the operator arm from the gate bracket to the output shaft. This is E. 2. Open the gate 90° (do not allow arms to scissor when open). Measure both sections of the arm (D and C). The arm lengths are correct as long as C+D=E (arm should be perpendicular to the gate in the open position as shown). > Figure: Top-view arm-adjustment diagrams. Diagram **1**, labeled **Top view - closed gate**, shows the gate closed and arm distance **E** from the gate bracket to the **Output Shaft**; arm adjustment points are labeled **Set Screws**. Diagram **2**, labeled **Top view - open gate**, shows **Gate Open 90°** with a curved directional arrow, the **Output Shaft**, **Set Screws**, and arm dimensions **C** and **D**. An adjacent circular shaded illustration indicates an incorrect scissoring arm position. ## Page 14 # INSTALLATION ## Step 5 Secure the Operator Arm Once the operator arm measurements are verified: 1. Weld the gate bracket to the gate. 2. Weld the short arm section. 3. Weld the long arm section. 4. Remove the set screws from the arm. **NOTE:** Completely weld around the outer tubing and bracket. 5. Adjust the nuts on the operator arm so the operator arm fits snug on the output shaft yet still allows enough room to swivel (the handle must be in a 90° position). 6. Tighten the handle by pushing it down. Test to make sure the operator arm does not slip on the output shaft. 7. Remove the pin from the vent plug on both the top and bottom gear boxes. > Figure: Installation illustrations showing three weld locations: the gate bracket at the gate, the short arm section at the operator, and the long arm section. Each detail shows a hand using a welding tool with sparks. > Figure: Operator output-shaft detail. A handle is shown being rotated upward, then pushed down into position; curved arrows indicate the movement. > Figure: Gearbox illustration with callouts **Top Gear Box** and **Bottom Gear Box**. A magnified detail shows a **Vent Plug** and removable **Pin**, with an arrow indicating removal of the pin. ## Page 15 # INSTALLATION > Figure: Warning banner with warning symbol and text: **WARNING** To prevent SERIOUS INJURY or DEATH from a moving gate: - ALL gate operator systems REQUIRE two independent entrapment protection systems for each entrapment zone. - Entrapment protection devices MUST be installed to protect anyone who may come near a moving gate. - Locate entrapment protection devices to protect in BOTH the open and close gate cycles. - Locate entrapment protection devices to protect between moving gate and RIGID objects, such as posts, walls, pillars, columns, or operator itself. ## Step 6 Install Entrapment Protection Entrapment protection MUST be installed according to the following UL 325 requirements: - Swing gate operators require the installation of the first external monitored entrapment protection device to function. - Every installation is unique. It is the responsibility of the installer to ensure that ALL entrapment zones are protected with an external monitored entrapment protection device, protecting both the open and close gate cycles. - **LiftMaster monitored external entrapment protection devices MUST be used with LiftMaster operators to meet UL325 requirements, see Accessories.** - Test ALL entrapment protection devices after completing installation of the operator. For testing instructions, refer to the manual provided with your entrapment protection device. ### Definitions **ENTRAPMENT:** The condition when a person is caught or held in a position that increases the risk of injury. **SWING GATE ENTRAPMENT ZONE:** Locations between a moving gate or moving, exposed operator components and a counter opposing edge or surface where entrapment is possible up to 1.8 m (6 ft) above grade. Such locations occur if during any point in travel: a. The gap between the bottom of a moving gate and the ground is greater than 101.6 mm (4 in) and less than 406 mm (16 in); or b. The distance between the center line of the pivot and the end of the wall, pillar, or column to which it is mounted when in the open or closed position exceeds 101.6 mm (4 in). Any other gap between a moving gate and fixed counter opposing edges or surfaces or other fixed objects is less than 406 mm (16 in) (examples are walls, curbs, berms or other immovable objects). *Illustrations provided by DASMA Gate Systems Safety Guide* > Figure: Example swing-gate installation site illustration. Text at top: **Illustration is for example only; your site may have additional entrapment zones which MUST be protected.** The left side is labeled **Public Side** and the lower/right area **Secure Side**. Two swing gates, operators, a vehicle, walls, curbs, and pedestrian gate are shown. Labels include: **Place the warning signs on both sides of the gate in clear view**; **Photoelectric sensor (public side)**; **Mount access control devices at least 6' (1.8 m) beyond the gate**; **Photoelectric sensor**; **Reflector for photoelectric sensor**; **Edge sensor**; **Earth ground**; **Curb**; **Pedestrian gate located near the swing gate. Make sure a separate pedestrian entrance is available and the path is clearly designated.**; **Take a photograph of the complete installation site for your records**. Multiple shaded areas are labeled **ENTRAPMENT ZONE**. A circular inset labeled **Cross Section** identifies an **Entrapment Zone** beneath a gate. ## Page 16 # INSTALLATION ## Wire Entrapment Protection Devices There are three options for wiring the entrapment protection devices depending on the specific device and how the device will function. Refer to the specific entrapment protection device manual for more information. These entrapment protection device inputs are for monitored devices, which include pulsed photoelectric sensors, resistive edge sensors, and pulsed edge sensors. **Only one monitored entrapment protection device may be wired to each input.** Additional entrapment protection devices may be wired to the expansion board. ## Control Board ### CLOSE EYES/INTERRUPT (2 Terminals) The CLOSE EYES/INTERRUPT input is for photoelectric sensor entrapment protection for the close direction. When an obstruction is sensed during gate closing the gate will open to the full open position and resets the Timer-to-Close. This input will be disregarded during gate opening. ### CLOSE EDGE (2 Terminals) The CLOSE EDGE input is for edge sensor entrapment protection for the close direction. When an obstruction is sensed during gate closing the gate will reverse to the full open position, disengaging the Timer-to-Close. This input will be disregarded during gate opening. ### OPEN EYES/EDGE (2 Terminals) The OPEN EYES/EDGE input is for photoelectric sensor or edge sensor entrapment protection for the open direction. When an obstruction is sensed during gate opening the gate will reverse for 4 seconds then stop. This input will be disregarded during gate closing. > Figure: Control-board wiring diagram. Terminal labels include **SHADOW**, **CLOSE EYES/INTERRUPT**, **CLOSE EDGE**, and **OPEN EYES/EDGE**, with positive and negative terminals marked **+** and **−**. Wiring examples are labeled **Close Photoelectric Sensors**, **Close Edge**, and **Open Photoelectric Sensors OR Open Edge**. A control board is shown below with a callout to the terminal area. ## Expansion Board ### EYE ONLY and COM Open or Close Direction Photoelectric Sensors, the functionality is based on the switch settings (located next to the terminals) **Switch set to CLOSE:** gate reverses fully when an obstruction is sensed **Switch set to OPEN:** gate reverses 4 seconds when an obstruction is sensed ### EYE/EDGE and COM Open or Close Direction Photoelectric Sensors or Edge Sensor, the functionality is based on the switch settings (located next to the terminals) **Switch set to CLOSE:** gate reverses fully when an obstruction is sensed **Switch set to OPEN:** gate reverses 4 seconds when an obstruction is sensed > Figure: Expansion-board wiring diagram. Switch labels include **OPEN CLOSE**, **EYE ONLY**, **EYE/EDGE 1**, **EYE/EDGE 2**, **EYE/EDGE 3**, and **COM**. Terminal labels include **SBC** and **OPN**. Wiring examples are labeled **Photoelectric Sensors** and **Photoelectric Sensors OR Edge Sensor**. A LiftMaster expansion board is shown below with a callout to the terminal area. ## Page 17 # INSTALLATION ## Step 7 Earth Ground Rod Use the proper earth ground rod for your local area. The ground wire must be a single, whole piece of wire. Never splice two wires for the ground wire. If you should cut the ground wire too short, break it, or destroy its integrity, replace it with a single wire length. 1. Install the earth ground rod within 3 feet (.9 m) of the operator. 2. Run wire from the earth ground rod to the operator. **NOTE:** If the operator is not grounded properly the range of the remote controls will be reduced and the operator will be more susceptible to lightning and surge damage. > Figure: Drawing of a ground rod installed vertically in soil. A wire runs from the rod top toward the operator, labeled “To operator.” A red vertical double-headed arrow beside the rod indicates depth. Callout reads: “Check national and local codes for proper depth.” ## Step 8 Power Wiring > Figure: Warning banner with warning icons and the word “WARNING.” To reduce the risk of SEVERE INJURY or DEATH: - ANY maintenance to the operator or in the area near the operator MUST NOT be performed until disconnecting the electrical power (AC or solar and battery) and locking-out the power via the operator power switch. Upon completion of maintenance the area MUST be cleared and secured, at that time the unit may be returned to service. - Disconnect power at the fuse box BEFORE proceeding. Operator MUST be properly grounded and connected in accordance with national and local electrical codes. **NOTE:** The operator should be on a separate fused line of adequate capacity. - ALL electrical connections MUST be made by a qualified individual. - DO NOT install ANY wiring or attempt to run the operator without consulting the wiring diagram. - ALL power wiring should be on a dedicated circuit and well protected. The location of the power disconnect should be visible and clearly labeled. - ALL power and control wiring MUST be run in separate conduit. The operator can be wired for either 120 Vac or 240 Vac or a solar panel (not provided). Follow the directions according to your application. An optional Transformer Kit (Model 3PHCONV) can be used to change the input voltage (208/240/480/575 Vac) to an output voltage of 120 Vac (refer to Accessories). For dual gate applications, power will have to be connected to each operator. Main power supply and control wiring MUST be run in separate conduits. **SOLAR APPLICATIONS:** For solar applications refer to *Solar Panels* section in the Appendix. Follow the directions according to your application. **NOTE:** If using an external receiver use shielded wire for the connections and mount the receiver away from the operator to avoid interference from the operator. | AMERICAN WIRE GAUGE (AWG) | STANDARD OPERATOR: 120 VAC, 10A (includes fully loaded outlets) | STANDARD OPERATOR: 120 VAC, 4A | STANDARD OPERATOR: 240 VAC, 2A | OPERATOR + ACCESSORIES POWERED BY TRANSFORMER KIT: 208 VAC, 4.8A | 240 VAC, 4.2A | 480 VAC, 2.1A | 575 VAC, 1.7A | |---|---:|---:|---:|---:|---:|---:|---:| | 14 | 100 (30.5 m) | 250 (76.2 m) | 1,000 (304.8 m) | 360 (109.7 m) | 480 (146.3 m) | 1,900 (579.1 m) | 2,800 (853.4 m) | | 12 | 160 (48.8 m) | 400 (121.9 m) | 1,600 (487.7 m) | 570 (173.7 m) | 750 (228.6 m) | 3,000 (914.4 m) | 4,500 (1,371.6 m) | | 10 | 250 (76.2 m) | 630 (192 m) | 2,500 (762 m) | 900 (274.3 m) | 1,200 (365.8 m) | 4,800 (1,463 m) | 7,100 (2,164.1 m) | | 8 | 400 (121.9 m) | 1,000 (304.8 m) | 4,000 (1,219.2 m) | 1,400 (426.7 m) | 1,900 (579.1 m) | 7,600 (2,316.5 m) | 11,300 (3,444.2 m) | | 6 | 636 (193.9 m) | 1,600 (487.7 m) | 6,400 (1950.7 m) | 2,300 (701 m) | 3,000 (914.4 m) | 12,100 (3,688.1 m) | 18,000 (5,486.4 m) | | 4 | 1,000 (304.8 m) | 2,500 (762 m) | 10,100 (3,078.5 m) | 3,700 (1,127.8 m) | 4,800 (1,463 m) | 19,300 (5,882.6 m) | 28,500 (8,686.8 m) | *Chart assumes: copper wire, 65°C, 5% drop* ## Page 18 # INSTALLATION All control wiring used to connect external devices to Class 2 circuits of the operator must be (QPTZ) Power-Limited Circuit Cables, Type CL2, CL2P, CL2R, or CL2X or other cable with equivalent or better electrical, mechanical, and flammability ratings. ## 240 VAC only The accessory outlet is disabled and cannot be used with the 240 Vac option. 1.

Gate MUST reverse on contact with an object. ## Introduction Your operator is designed with electronic controls to make travel limit and force adjustments easy. The adjustments allow you to program where the gate will stop in the open and close position. The electronic controls sense the amount of force required to open and close the gate. The force is adjusted automatically when you program the limits but should be fine tuned using the REVERSAL FORCE dial on the control board (refer to *Fine Tune the Force* section) to compensate for environmental changes. The limit setup LEDs (located next to the SET OPEN and SET CLOSE buttons) indicate the status of the limits, refer to the table to the right. The limits can be set using the control board (below) or a remote control (refer to *Limit Setup with a Remote Control* in the Appendix). Setting the limits with a remote control requires a 3-button remote control programmed to OPEN, CLOSE, and STOP. *NOTE: The TEST buttons on the control board will not work until the limits have been set and the required entrapment protection devices are installed.* | SET OPEN LED | SET CLOSE LED | OPERATOR MODE | EXPLANATION | |---|---|---|---| | OFF | OFF | NORMAL MODE | Limits are set | | BLINKING | BLINKING | LIMIT SETTING MODE | Limits are not set | | BLINKING | ON | LIMIT SETTING MODE | Open limit is not set | | ON | BLINKING | LIMIT SETTING MODE | Close limit is not set | | ON | ON | LIMIT SETTING MODE | Limits are set | ## Initial Limits and Force Adjustment **For dual gate applications the limits will have to be set for each operator. The arm MUST be attached to the operator before setting the limits and force.** 1. Press and release the SET OPEN and SET CLOSE buttons simultaneously to enter limit setting mode. 2. Press and hold one of the MOVE GATE buttons to move the gate to the open or close limit. 3. Press and release the SET CLOSE or SET OPEN button depending on which limit is being set. 4. Press and hold one of the MOVE GATE buttons to move the gate to the other limit. 5. Press and release the SET CLOSE or SET OPEN button depending on which limit is being set. 6. Cycle the gate open and close. This automatically sets the force. **When limits are set properly the operator will automatically exit limit setting mode.** > Figure: Control board with six numbered circular callouts depicting limit setup sequence. > **1:** Hands press **SET OPEN** and **SET CLOSE** simultaneously. > **2:** **MOVE GATE** buttons with up and down arrows; text indicates pressing and holding to move the gate. > **3:** **SET OPEN** and **SET CLOSE** buttons; label indicates pressing and releasing to set the limit. > **4:** **MOVE GATE** buttons with directional arrows. > **5:** **SET OPEN** and **SET CLOSE** buttons and a MOVE GATE button; label indicates pressing and releasing. > **6:** Gate illustration with curved arrow indicating cycling the gate open and closed. ## Page 25 # ADJUSTMENT ### Fine Tune the Force Once the initial limits have been set, the REVERSAL FORCE DIAL on the control board is used for fine tuning the force where wind or environmental changes may affect the gate travel. The REVERSAL FORCE DIAL is set to minimum at the factory. Based on the length and weight of the gate it may be necessary to make additional force adjustments. The force setting should be high enough that the gate will not reverse by itself nor cause nuisance interruptions, but low enough to prevent serious injury to a person. The force setting is the same for both the open and close directions. 1. Open and close the gate with the TEST BUTTONS. 2. If the gate stops or reverses before reaching the fully open or closed position, increase the force by turning the force control slightly clockwise. 3. Perform the “Obstruction Test” after every limit and force setting adjustment (see below). > Figure: Illustration of an operator control board with enlarged callouts. A callout labeled “TEST BUTTONS” shows three vertically arranged buttons: green “OPEN,” green “CLOSE,” and orange “STOP.” A second callout labeled “REVERSAL FORCE” shows a red adjustment dial with a curved arrow above it; “MIN” is at the lower left and “MAX” at the lower right, with “60” printed beside the dial. The board includes readable labels including “SET OPEN,” “SET CLOSE,” “LEARN,” “TEST BUTTONS,” “REVERSAL FORCE,” “DIAGNOSTICS,” “STATUS,” “BATT FUSE 30 AMP,” and “AC & BATT FAIL POWER.” ### Adjust the Limits After both limits are set and the operator is ready to run, one limit can be adjusted independently from the other by following steps 1-3 of the Initial Limit and Force Adjustment section. > Figure: Illustration of the operator control board with an enlarged callout showing two hands pressing two buttons labeled “SET OPEN” and “SET CLOSE.” ### Obstruction Test The operator is equipped with an inherent (built in to the operator) obstruction sensing device. If the gate encounters an obstruction during motion, the operator will reverse direction of the gate and then stop. The following procedure will test ONLY the inherent (built in to the operator) obstruction sensing device: 1. Open and close the gate with the TEST BUTTONS, ensuring that the gate is stopping at the proper open and close limit positions. 2. Place an object between the open gate and a rigid structure. Make sure that any external entrapment protection devices will NOT be activated by the object. 3. Run the gate in the close direction. The gate should stop and reverse upon contact with the object. If the gate does not reverse off the object, reduce the force setting by turning the force control slightly counter-clockwise. The gate should have enough force to reach both the open and close limits, but MUST reverse after contact with an object. 4. Repeat the test for the open direction. **Test the operator after any adjustments are made.** > Figure: Three-step obstruction-test illustration. Step 1 shows the control board and an enlarged callout of the “TEST BUTTONS” (green OPEN and CLOSE buttons and orange STOP button) and the “REVERSAL FORCE” dial, with a curved adjustment arrow and “MAX” visible. Step 2 shows a sliding gate moving toward a small object placed between the open gate and a rigid post/structure; a red arrow indicates the gate’s closing direction. Step 3 shows the gate contacting the object and reversing; red arrows indicate movement away from the object. ## Page 26 # PROGRAMMING ## Remote Controls (Not Provided) A total of 50 Security+ 2.0® remote controls or KPW250 keypads and 2 keyless entries (1 PIN for each keyless entry) can be programmed to the operator. When programming a third keyless entry to the operator, the first keyless entry will be erased to allow the third keyless entry to be programmed. When the operator’s memory is full it will exit the programming mode and the remote control will not be programmed. The memory will need to be erased before programming any additional remote controls. *NOTE: If installing an 86LM to extend the range of the remote controls DO NOT straighten the antenna.* > Figure: Illustration of an operator control board with two magnified callouts. Left callout is labeled “LEARN” and shows a finger pressing a yellow button. Readable labels include “OFF,” “XMITTER,” and “NETWORK.” Right callout is labeled “TEST BUTTONS” and shows three vertically arranged buttons: green OPEN, green CLOSE, and orange STOP. Additional visible labels include “TIMER,” “WORK,” and “LIMIT LOW.” Arrows point from the callouts to locations on the control board. There are 3 different options for programming the remote control depending on how you would like the remote control to function. Choose a programming option: | OPTION | DESCRIPTION | PROGRAMMING STEPS | |---|---|---| | Single button as OPEN only | Program a single button on the remote control for open only.

Release the handle on the operator arm to allow the gate to be opened and closed manually. On a dual gate application the handle must be released on both operators. To resume normal function tighten the handle by pushing it down. ## Reset Switch The reset switch is located on the front of the operator and serves several functions. Toggling the reset switch will stop a moving gate during a normal open/close cycle, like a stop button. The operator does not need to be reset after doing this. The reset switch will disable the gate in the present position and will energize the solenoid lock for two minutes and disable the maglock for two minutes. > Figure: Operator housing with its top Manual Disconnect Handle shown removed above the unit, with a dashed alignment line and arrow indicating installation/removal. Two circular close-ups show fingers operating the front reset switch. Labels: “Manual Disconnect Handle,” “Normal operation,” and “Reset/Disconnect.” Curved arrows indicate switch movement. ## Operator Alarm If a contact sensor detects an obstruction twice consecutively the alarm will sound (up to 5 minutes) and the operator will need to be reset. When the inherent force of the operator (RPM/current sensor) detects the following (twice consecutively) the alarm will sound (up to 5 minutes) and the operator will need to be reset. A. The operator arm or gate is incorrectly installed. B. The gate does not meet specifications. C. Gate hinges are too tight or broken and the gate is not moving freely. D. The gate is moving and a car pushes the gate. E. A foreign object is on the gate frame while the gate is moving. F. The gate hits the driveway or curb and gets stuck or bent in an awkward position. Remove any obstructions. Press the reset button to shut off the alarm and reset the operator. After the operator is reset, normal functions will resume. The operator alarm will beep 3 times with a command if the battery is low. > Figure: Six illustrated alarm-condition examples labeled A through F.

Starburst symbols mark contact points. ## Remote control ### Single Button Control (SBC) Functionality Once the remote control has been programmed the operator will operate as follows: When gate is in the closed position, activation of the remote control button will open the gate. During the open cycle another activation of the remote control will stop the gate and the next activation of the remote control will close the gate. When the gate is in the open position, activation of the remote control button will close the gate. If the remote control is activated while the gate is closing, the gate will stop and the next activation will open the gate. ## Page 31 # ACCESSORY WIRING All control wiring used to connect external devices to Class 2 circuits of the operator must be (QPTZ) Power-Limited Circuit Cables, Type CL2, CL2P, CL2R, or CL2X or other cable with equivalent or better electrical, mechanical, and flammability ratings. ## External control devices ### EXIT (2 Terminals) This input is a soft open command (maintained switch does not override external safeties and does not reset alarm condition). Used for exit probe, telephone entry, external exit loop detector, or any device that would command the gate to open. - Opens a closing gate and holds open an open gate, if maintained, pauses Timer-to-Close at OPEN limit. ### SHADOW (2 Terminals) This input is used for external shadow loop detector when loop is positioned under the swing of the gate. - Holds open gate at open limit - Only active when the gate is at the OPEN limit, disregarded at all other times - Pauses Timer-to-Close at OPEN limit ### INTERRUPT (2 Terminals) This input is used for photoelectric sensors and external interrupt loop detector when loop is on the outside of the gate. - Holds open gate at open limit - Stops and reverses a closing gate to open limit - Pauses Timer-to-Close at OPEN limit, activates quick close and anti-tailgate features when enabled on the expansion board > Figure: “Access control device wiring” diagram.

ON: When CLOSE EYES/Interrupt loop is deactivated it causes an opening or a stopped gate to close (ignores the Timer-to-Close). 2. **AC FAIL switch:** OPEN: Loss of AC power will cause the gate to open approximately 15 seconds after AC power fail and remain OPEN until AC power is restored (enabling the Timer-to-Close). BATT: With loss of AC power, gate will remain in present position and operator is powered from batteries. 3. **EXIT FAIL switch:** When set to OPEN, if the EXIT plug-in loop detector (Model LOOPDETL M) detects a fault, then the gate will open and remain open until fault is cleared. When set to CLOSE, then plug-in EXIT loop detector faults are ignored (EXIT loop is faulted and inoperative). 4. **ANTI-TAIL switch:** OFF: When CLOSE EYES/Interrupt loop is activated it causes a closing gate to stop and reverse. ON: When CLOSE EYES/Interrupt loop is activated it causes a closing gate to pause. Once the vehicle is clear the gate will continue to close. 5. **AUX RELAY switches:** Set the AUX RELAY switches as needed to obtain the desired function as shown on the following page. 6. **EYE/EDGE switches:** Set the EYE/EDGE switches as needed to obtain the desired OPEN or CLOSE functionality. 7. **1, 2, and 3 LEDs:** LEDs indicating the status of the EYE/EDGE inputs.

To determine the actual cycles that the gate operator has run (in thousands), set all three Aux Relay switches to the ON setting for Aux Relay 1. The Expansion Board’s 1, 2, and 3 LEDs will blink out the cycle count, with 1 LED blinking 1000’s, 2 LED blinking 10,000’s, 3 LED blinking 100,000’s, and simultaneously all three LED’s blink 1,000,000’s (e.g. 1 LED blinks 3 times, 2 LED blinks 6 times, and 3 LED blinks once. Cycle count is 163,000.). Cycle count displayed is between 1,000 and 9,999,000 cycles. After servicing, set Aux Relay switches back to their appropriate positions. Cycle count cannot be reset or changed. If under 1,000 cycles the 1, 2, and 3 LEDs will turn on for 10 seconds, then turn off. **NOTE:** The expansion board will flash the cycle count 3 times then all the LEDs will turn on solid for 10 seconds then turn off. # Auxiliary relay wiring example > Figure: Expansion board auxiliary relay terminals.

Upon completion of maintenance the area MUST be cleared and secured, at that time the unit may be returned to service. - Disconnect power at the fuse box BEFORE proceeding. Operator MUST be properly grounded and connected in accordance with national and local electrical codes. **NOTE:** *The operator should be on a separate fused line of adequate capacity.* - NEVER let children operate or play with gate controls. Keep the remote control away from children. - ALWAYS keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF THE MOVING GATE. - The entrance is for vehicles ONLY. Pedestrians MUST use separate entrance. - Test the gate operator monthly. The gate MUST reverse on contact with an object or reverse when an object activates the noncontact sensors. After adjusting the force or the limit of travel, retest the gate operator. Failure to adjust and retest the gate operator properly can increase the risk of INJURY or DEATH. - Use the manual disconnect release ONLY when the gate is NOT moving. - KEEP GATES PROPERLY MAINTAINED. Read the owner’s manual. Have a qualified service person make repairs to gate hardware. - ALL maintenance MUST be performed by a LiftMaster professional. - Activate gate ONLY when it can be seen clearly, is properly adjusted and there are no obstructions to gate travel. - To reduce the risk of FIRE or INJURY to persons use ONLY LiftMaster part 29-NP712 for replacement batteries. - **● SAVE THESE INSTRUCTIONS.** > ⚠️ **CAUTION** > • ALWAYS wear protective gloves and eye protection when changing the battery or working around the battery compartment. # Maintenance Chart **Disconnect all power (AC, solar, battery) to the operator before servicing.** The operator's AC Power switch ONLY turns off AC power to the control board and DOES NOT turn off battery power. ALWAYS disconnect the batteries to service the operator. | DESCRIPTION | TASK | MONTH | 6 MONTHS | 3 YEARS | |---|---|---:|---:|---:| | Entrapment Protection Devices | Check and test inherent (built into the operator) and external devices for proper operation | X | | | | Warning Signs | Make sure they are present and replace if worn or broken, see *Accessories* | X | | | | Manual Disconnect | Check and test for proper operation | | X | | | Sprockets and Chains | Check for excessive slack and lubricate | | X | | | Gate | Inspect for wear or damage; ensure it still complies with ASTM F2200, see page 5 | X | | | | Accessories | Check all for proper operation | | X | | | Electrical | Inspect all wire connections | | X | | | Chassis Mounting Bolts | Check for tightness | | X | | | Operator | Inspect for wear or damage | | X | | | Batteries | Replace | | | X | **NOTES:** - Severe or high cycle usage will require more frequent maintenance checks. - It is suggested that while at the site voltage readings be taken at the operator.

The operator alarm will beep 3 times with a command if the battery is low. Batteries do not perform well in extremely cold temperatures. For best performance, the batteries should be replaced every 3 years. Use only LiftMaster part 29-NP712 for replacement batteries. The batteries contain lead and need to be disposed of properly. The operator comes with two 7AH batteries. Two 33AH batteries (A12330SGLPK), Solar Harness Kit (K94-37236) with additional battery tray (K10-36183) may be used in place of the 7AH batteries. **NOTE:** *If your application includes a heater, two 33AH batteries will not fit into the operator enclosure.* ## Page 38 # TROUBLESHOOTING > Figure: Warning box with electrical shock symbol.

SEE ACCESSORIES** ### Solar Application Requirements - A minimum of two 10W solar panels in series (Model SP10W12V). - A maximum of six 10W solar panels (Model SP10W12V). - Battery Tray (Model K10-36183) required for 33AH batteries. - Solar Harness Kit (Model K94-37236). - A heater cannot be used with a solar application. ### Solar Zones Solar panel recommendations are based upon the average solar radiation and the temperature effects on batteries in the given zones as shown on the map below. Local geography and weather conditions may require additional solar panels. Solar powered gate operator installations are not supported in northern climates due to cold weather and a reduced number of hours of sunlight during the winter months.

Refer to the Programming section. ## Initial Limits and Force Adjustment **For dual gate applications the limits will have to be set for each operator. The gate MUST be attached to the operator before setting the limits and force.** Ensure the gate is closed. 1. Press and release the SET OPEN and SET CLOSE buttons simultaneously to enter limit setting mode. 2. Press and hold the OPEN or CLOSE button on the remote control until the gate reaches the desired open position. The gate can be jogged back and forth using the OPEN and CLOSE buttons on the remote control. 3. Once the gate is in the desired open position, press and release the STOP button on the remote control. 4. Press and release the OPEN button on the remote control again to set the open limit. 5. Press and hold the CLOSE or OPEN button on the remote control until the gate reaches the desired close position. The gate can be jogged back and forth using the OPEN and CLOSE buttons on the remote control. 6. Once the gate is in the desired close position, press and release the STOP button on the remote control. 7. Press and release the CLOSE button on the remote control again to set the close limit. 8. Cycle the gate open and close. This automatically sets the force. When limits are set properly the operator will automatically exit limit setting mode. Refer to the *Adjustment* section and follow the instructions for *Fine Tune the Force* and *Obstruction Test*. Perform the "Obstruction Test" after every limit and force setting adjustment. ## Adjust the limits If the limits have already been set the operator will exit the limit setting mode after resetting each limit. ### Set the Close Limit Only 1. Press and release the SET OPEN and SET CLOSE buttons simultaneously to enter limit setting mode. 2. Press and hold the CLOSE button on the remote control until the gate reaches the desired close position. The gate can be jogged back and forth using the OPEN and CLOSE buttons on the remote control. 3. Once the gate is in the desired close position, press and release the STOP button on the remote control. 4. Press and release the CLOSE button on the remote control again to set the close limit. When the close limit is set properly the operator will automatically exit limit setting mode. ### Set the Open Limit Only 1. Press and release the SET OPEN and SET CLOSE buttons simultaneously to enter limit setting mode. 2. Press and hold the OPEN button on the remote control until the gate reaches the desired open position. The gate can be jogged back and forth using the OPEN and CLOSE buttons on the remote control. 3. Once the gate is in the desired open position, press and release the STOP button on the remote control. 4. Press and release the OPEN button on the remote control again to set the open limit.
