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) - Guards for Exposed Rollers - Photoelectric Sensors - Screen Mesh - 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 openings of a horizontal slide gate are guarded or screened from the bottom of the gate to a minimum of 6 feet (1.8 m) above the ground to prevent a 2-1/4 inches (6 cm) diameter sphere from passing through the openings anywhere in the gate, and in that portion of the adjacent fence that the gate covers in the open position. c. 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. 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, such as at the leading edge, trailing edge and post mounted both inside and outside of a vehicular horizontal slide gate. 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. 4 ## Page 5 SAFETY # Gate Construction Information Vehicular gates should be installed in accordance with ASTM F2200: Standard Specification for Automated Vehicular Gate Construction.

Before trenching, contact underground utility locating companies. Conduit must be UL approved for low and high voltage. Consider the operator placement BEFORE installing the pad or post. > Figure: Illustration of a sliding vehicular gate across a driveway, with concrete pads at the gate/operator area. Arrows label **Concrete Pads**. ### Safety Entrapment protection devices are required to protect against any entrapment or safety conditions encountered in your gate application. Install a warning sign (two provided) on the inside and outside of the property, where easily visible. > Figure: Illustration of a sliding gate and driveway. A leader points to a **Warning Sign** on the gate. Red labels mark **Entrapment Zone** on both sides of the gate and at the gate travel area. ### Gate Gate must be constructed and installed according to ASTM F2200 standards (refer to page 4). Gate must fit specifications of operator (refer to specifications). > Figure: Illustration of a sliding gate installation. Two enlarged circular details are shown. Left detail depicts covered catch rollers and is captioned: **SAFETY CATCH ROLLERS** — Install catch rollers with safety covers on the side of a post or wall with a minimal distance of half an inch between the rollers and gate. Right detail shows a gate catch post crossed out and labeled **Closing Gate**; caption: **DO NOT** use a gate catch post. Because the coasting distance may vary due to changes in temperature, it is NOT recommended to install a catch post in front of the gate's path. To do so will cause the gate to hit the post in certain instances. ### Additional Accessories The vehicle loops allow the gate to stay open when vehicles are obstructing the gate path. Suggested for vehicles 14 feet (4.27 m) or longer. Vehicle loops are not required but are recommended. Before installing your Access Control Device(s) be sure to complete a site survey and determine the best device for your site needs. > Figure: Illustration of a sliding gate with driveway loop detectors. Labels identify **Access Control Device**, **Vehicle Loops**, and **Outside Property**. ## Page 9 # INSTALLATION > ⚠️ **CAUTION** > > - To AVOID damaging gas, power or other underground utility lines, contact underground utility locating companies BEFORE digging more than 18 inches (46 cm) deep. > - ALWAYS wear protective gloves and eye protection when changing the battery or working around the battery compartment. # Types of Installations ## Standard Installation > Figure: Illustration of a closed sliding gate between walls.

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. **SLIDE GATE ENTRAPMENT ZONE:** An entrapment zone exists if at any point during travel, the gap between the gate and any opposing fixed edge or surface such as posts, walls, pillars, columns or operator itself, is less than 16" (406 mm) in a location up to 6 ft. (1.8 m) above grade. *Illustrations provided by DASMA Gate Systems Safety Guide* > Figure: Illustrated example of a sliding gate installation showing public and secure sides, a vehicle, sliding gate, pedestrian gate, wall, posts, sensors, and entrapment zones.

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. A callout enlarges terminal blocks labeled “SHADOW,” “CLOSE EYES/INTERRUPT,” “CLOSE EDGE,” and “OPEN EYES/EDGE.” Wiring diagrams show “Close Photoelectric Sensors,” “Close Edge,” and “Open Photoelectric Sensors OR Open Edge.” Plus and minus terminal polarity symbols are shown.

The operator with the LOCK/BIPART DELAY switch ON will delay from the close limit when opening and be the first to close from the open limit. SLIDE GATE APPLICATIONS: Not applicable, set to OFF. - **SYNCHRONIZED CLOSE** The BIPART DELAY is also used in applications where one gate travels a longer distance than the other. To synchronize the closing of the gates, set the LOCK/BIPART DELAY switch to ON for both operators. > Figure: Control board with magnified view of DIP switches. Magnification labels include “BATT FAIL,” “BIPART DELAY,” “OPEN,” “CLOSE,” “OFF,” and “ON.” The BIPART DELAY switch is shown with OFF at the top and ON at the bottom. 21 ## Page 22 # INSTALLATION ## Step 9 Install the cover *Before installing the cover, follow the instructions in the Adjustment section to adjust the limits and force.* The operator cover consists of two pieces: a rear cover and a front cover. The front cover can easily be removed to access the electrical box. To access the reset switch slide the access door up. The front cover and access door can be locked with the key. 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 gate MUST be attached to the operator before setting the limits and force.** **For slide gate applications the open limit and closed limit MUST be set at least four feet apart.** 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 button 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 diagram with six numbered callouts illustrating limit setup. > 1. Two hands press “SET OPEN” and “SET CLOSE” buttons simultaneously. > 2. “MOVE GATE” up and down arrow buttons move the gate; text reads “TO ENTER LIMIT SETUP.” > 3. SET OPEN and SET CLOSE buttons shown. > 4. MOVE GATE buttons shown with text “PRESS & RELEASE TO EXIT LIMIT SETUP.” > 5. SET OPEN and SET CLOSE buttons shown. > 6. Swing gate illustration with a red directional arrow indicating a gate cycle. 23 ## Page 24 # 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: Control board with enlarged callouts for controls. “TEST BUTTONS” shows green OPEN and CLOSE buttons and an orange STOP button. “REVERSAL FORCE” shows a dial with a curved rotation arrow and markings “MIN” and “MAX”; the dial is depicted at approximately 60. Additional partially visible labels include “EMITTER,” “NETWORK,” and “REVERSAL FORCE.” ## 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: Control board with a magnified inset of two hands pressing the “SET OPEN” and “SET CLOSE” buttons. ## 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 diagram. > 1. Control board callout shows TEST BUTTONS and REVERSAL FORCE dial. > 2. Open swing gate moves toward a rigid post or structure, indicated by a red arrow. > 3. An object is placed in the gate path near the rigid structure; the gate is shown contacting the object. 24 ## Page 25 # 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.

See *Adjust Limits* section. **2 SET CLOSE Button:** The SET CLOSE button sets the CLOSE limit. See *Adjust Limits* section. **3 MOVE GATE Buttons:** The MOVE GATE buttons will either open or close the gate when the operator is in Limit setting mode. See *Adjust Limits* section. **4 BATT FAIL:** - When AC power is OFF and battery voltage is critically low the gate will latch at a limit until AC power is restored or batteries voltage increases. - Option select switch set to OPEN forces gate to automatically open and then latch at the OPEN limit until AC power is restored or battery voltage increases. - Option select switch set to CLOSE forces gate to latch at CLOSE limit if at CLOSE limit or on next CLOSE command until AC power restored or battery voltage increases. - Constant pressure on a hard command input overrides to open or close the gate. - Critically low battery is less than 23 V **5 BIPART DELAY Switch:** The LOCK/BIPART DELAY switch is used only for dual gates. See Bipart Delay section. **6 LEARN Button:** The LEARN button is for programming remote controls and the network. **7 TIMER-TO-CLOSE dial:** The TIMER-TO-CLOSE (TTC) dial can be set to automatically close the gate after a specified time period. The TTC is factory set to OFF. If the TTC is set to the OFF position, then the gate will remain open until the operator receives another command from a control. Rotate the TIMER-TO-CLOSE dial to the desired setting. The range is 0 to 180 seconds, 0 seconds is OFF. *NOTE: Any hard command, single button control, open command on the control board prior to the TTC expiring will close the gate. The TTC is reset by any signals from the open controls, loops, close edges, and close photoelectric sensors (IR’s).* **8 REVERSAL FORCE dial:** The REVERSAL FORCE dial fine tunes the force. See *Force Adjustment* section. **9 TEST BUTTONS:** The TEST BUTTONS will operate the gate (OPEN, STOP and CLOSE). **10 STATUS LEDs:** The STATUS LEDs indicate the status of the operator.

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: Drawing of a LiftMaster gate operator and its reset switch. A callout shows a finger pressing the switch labeled “Reset/Disconnect,” with a curved arrow. A second callout shows the switch in “Normal operation,” with a curved arrow. The operator bears the “LiftMaster” label. ### 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 gate is hitting a wall or vehicle. B. The gate does not meet specifications. C. Debris is on the gate's track such as mud, rocks, dirt, etc. D. The gate has one or more broken axles or wheels. E. The gate wheel is off the gate rail. 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: Five illustrated obstruction examples labeled A through E. A shows a sliding gate striking a vehicle. B shows a damaged/broken gate wheel assembly. C shows debris on the gate track. D shows a broken axle or wheel condition. E shows a gate wheel off the gate rail. Impact/starburst symbols indicate contact or obstruction. ### 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. 29 ## Page 30 # 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 path 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. A control-board terminal block is enlarged and labeled “FIRE DEPT.

Relay activates prior to motor activation and during motor run. Relay is off when motor is off. > Figure: Wiring diagram labeled “CONTROL BOARD” showing lock terminals labeled “LOCK,” “N.C.,” and “COM” wired to a “MAGLOCK.” A power supply is shown and labeled “NOT PROVIDED,” with positive and negative polarity symbols. ### Miscellaneous wiring #### Three button control station (4 Terminals) - OPEN and COM: Opens a closed gate. Hard open (maintained switch overrides external safeties and resets alarm condition). If maintained, pauses Timer-to-Close at OPEN limit. Opens a closing gate and holds open an open gate (within line-of-sight). - CLOSE and COM: Closes an open gate. Hard close (maintained switch overrides external safeties and resets alarm condition within line-of-sight) - STOP and COM: Stops a moving gate. Hard stop (maintained switch overrides Open and Close commands and resets alarm condition). If maintained, pauses Timer-to-Close at OPEN limit. Overrides Open and Close commands (within line-of-sight). #### Fire department open input (2 Terminals) Acts as hard open. Maintained input overrides (ignores) external safeties (photoelectric sensor and edge), pauses Timer-to-Close momentary input logic as single button control and safeties remain active, re-enables Timer-to-Close. #### Accessory power 24 VDC, MAX 500 mA (4 Terminals) - SWITCHED: Switched ON with gate motion and at the open limit when Timer-to-Close is active. Turns off 5 seconds after motion. - UNSWITCHED: 24 Vdc voltage out to power accessories, always ON. > Figure: “MAIN CONTROL BOARD” wiring diagram for a “Three Button Control Station.” Terminal labels on the board are “OPEN,” “CLOSE,” “STOP,” “COMMON,” “FIRE DEPT.,” and “OPEN.” The station wiring is labeled “Open,” “Close,” “Stop,” “N.C.,” “Com,” “Fire Dept.,” and “Com.” The fire department connection is labeled “Fire Department.” > Figure: “MAIN CONTROL BOARD” accessory-power 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. Also used to check the firmware version of the expansion board: 1. Locate the 1, 2, and 3 LEDs on the expansion board. 2. Disconnect AC/DC power to the main control board for 15 seconds. 3. Connect power. The 1, 2, and 3 LEDs will flash in sequence until the main control board firmware revision is displayed. When the green POWER LED glows solid the LED 1 will flash the version number, then stop, then the LED 2 will flash the revision number (for example: For version 5.1 when the green POWER LED is solid the LED 1 will flash 5 times, then stop, then the LED 2 will flash once). 8. **MAIN BOARD input:** Input Connection for the main board connector. 9. **Input LEDs:** LEDs indicating the status of the SBC, OPN, CLS, and STP inputs. 10. **Loop detector inputs:** Inputs for the Plug-In Loop Detectors (Model LOOPDETL M) 11. **Wireless edge input:** Input for the Wireless Edge Kit (Model LMWEKITU) > Figure: Expansion board diagram with numbered callouts 1–11.

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: Illustration of the expansion board AUX RELAY 1 and AUX RELAY 2 switch banks and terminal blocks.

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. - Limits may have to be readjusted after any major drive chain adjustments. - If lubricating chain, use only lithium spray. Never use grease or silicone spray. - It is suggested that while at the site voltage readings be taken at the operator. Using a digital voltmeter, verify that the incoming voltage to the operator is within ten percent of the operator’s rating. 35 ## Page 36 # MAINTENANCE ## Batteries Batteries will degrade over time depending on temperature and usage. 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), with Solar Harness Kit (K94-37236) may be used in place of the 7AH batteries. ## Drive Train Over time, the drive chain on the operator will stretch and need to be tightened.

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). - 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. The cycles/day ratings are approximations. Ratings vary based on gate construction, installation, and temperature. Solar panels cannot be installed in areas that experience long periods of heavy fog, lake effect snow, or rain. > Figure: Color-coded map of North America showing solar zones. Legend at upper left: > > 1 — **ZONE 1 (6 Hours of Sunlight/Day):** Ideal for solar application. > > 2 — **ZONE 2 (4 Hours of Sunlight/Day):** Recommended for solar application. > > 3 — **ZONE 3 (2 Hours of Sunlight/Day):** Success of solar application will depend on type of gate operator and location of the solar panel. > > Blue — **NOT AVAILABLE**. > > The southern United States and Hawaii inset are orange, marked with circled “1”.

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. When the open limit is set properly the operator will automatically exit limit setting mode. > Figure: Illustration of a control board.
