The hazard may come from something mechanical or from electric shock. Read the warnings carefully. When you see this Signal Word on the following pages, it will alert you to the possibility of damage to your gate and/or the gate operator if you do not comply with the cautionary statements that accompany it. Read them carefully. **IMPORTANT NOTE:** - BEFORE attempting to install, operate or maintain the operator, you must read and fully understand the manual provided with your operator and follow all safety instructions. - DO NOT attempt repair or service of your gate operator unless you are a Trained Gate System Technician. > Figure: Three orange safety-signal panels. The first reads “WARNING” with a black triangle containing an exclamation mark, labeled “MECHANICAL.” The second reads “WARNING” with a black triangle containing an electrical-shock symbol, labeled “ELECTRICAL.” The third reads “CAUTION.” No arrows, dimensions, torque specifications, or wire specifications are shown. 1 ## Page 3 # BEFORE YOU BEGIN ## UL COMPLIANT GATE OPERATORS The UL standard requires gate operators to monitor for the presence of external entrapment devices and any fault conditions. LiftMaster has not only updated their line of gate operators to meet the new UL 325 standard, they have also taken the opportunity to add a common user interface and common feature sets across the line to increase performance, safety and accessibility. All LiftMaster UL compliant gate operators will come with external monitored retro-reflective photoelectric sensors. > Figure: Illustration of LiftMaster monitored retro-reflective photoelectric sensors, enclosed by an oval outline. Caption: “LiftMaster Monitored Retro-Reflective Photoelectric Sensors (Model LMRRU).” No arrows, dimensions, torque specifications, or wire specifications are shown. ## UL325 ENTRAPMENT PROTECTION REQUIREMENTS ### 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 the operator itself, is less than 16” (406 mm) in a location up to 6 ft. (1.8 m) above grade. **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”) and less than 406 mm (16”); 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”). Any other gap between a moving gate and fixed counter opposing edges or surfaces or other fixed objects is less than 406 mm (16”) (examples are walls, curbs, berms or other immovable objects). **INDEPENDENT MONITORED ENTRAPMENT PROTECTION DEVICE:** An entrapment protection device is independent if it is a different type (photoelectric sensors, edge device, inherent protection device) from the other devices in the same entrapment zone. Use the *Site Planning Safety Checklist* to identify entrapment zones found in your installation. ### REQUIREMENTS - A **minimum of two** independent monitored entrapment protection devices are required to be installed at each entrapment zone. - It is the responsibility of the installer to install external monitored entrapment protection devices for **each entrapment zone**. - A SLIDE gate operator will only operate with a **minimum of two** independent monitored entrapment protection devices installed in each direction; two in the open direction and two in the closed direction. - A SWING gate operator will only operate with a minimum of two independent monitored entrapment protection devices installed in either the open or closed direction. If no entrapment zone exists in the other direction, an external entrapment protection device is NOT required in that direction. Liftmaster Swing and Slide gate operators have an inherent entrapment protection device built-in. ***The installer MUST provide one additional entrapment protection device for each entrapment zone.*** Acceptable entrapment protection device types include: - Inherent (built into the operator) - LiftMaster monitored external photoelectric sensors, see Accessory page of the operator manual for acceptable sensors. - LiftMaster monitored external edge sensors, see Accessory page of the operator manual for acceptable sensors. 2 ## Page 4 # BASIC TROUBLESHOOTING ## MULTI-METERS The image is an example of a generic multimeter. LiftMaster currently has no intended affiliations with this multi-meter manufacturer. This is not an endorsement for this particular meter model. When shopping for a meter, look for a meter able to fit in a shirt pocket or clip on a belt. A meter with an audio signal (buzzer) for continuity checks is recommended. For testing motor current, a clamp-on ampmeter is preferred. > Figure: Illustration of a yellow and gray handheld digital multimeter with a display, rotary selector dial, buttons, input sockets, and red and black test leads. No readable manufacturer or model label is shown. No arrows, dimensions, torque specifications, or wire specifications are shown. ## CHECKING OHMS/CONTINUITY When checking the operation of a switch, select the ohm mode on multimeter. (The ohm symbol is Ω). Make sure the test leads are plugged into the correct sockets for reading ohms. If there is more than one setting in the ohm section of the meter, select the one with the audio signal. To test a limit switch, connect one test lead to the Common prong and the other to the Normally Closed prong. The meter should read 0 resistance or very low resistance. The electricity is flowing from the Common prong to the Normally Closed prong. This demonstrates continuity. Activate the switch, the meter will read Infinite resistance or no continuity. Infinite ohms is often expressed as “OL” on the meter, but do not confuse this with zero ohms. In continuity mode, a tone indicates zero ohms. The contacts inside the switch are no longer touching between the Common prong and the Normally Closed prong. Move the test lead from Normally Closed to Normally Open. While the activation arm is not pressed, the meter should read open circuit, demonstrating no continuity. Activating the arm should read 0 resistance, demonstrating continuity. The procedure is called a “Continuity Check” and is used to check for a continuous flow of electricity. ## CHECKING VOLTAGE A multimeter may have several settings for checking voltages. The number associated with each setting is the maximum voltage able to be read. A meter may be damaged if connected to a higher voltage than selected. Either AC or DC must be selected prior to testing any circuit. AC stands for alternating current and DC stands for direct current. AC is usually the incoming line voltage, i.e. 115 VAC, 460 VAC and so on. 24 VAC is also found in the control circuit of an operator. DC is usually a power source from a battery or the control voltage in a logic board. Set the meter to VOLTS AC at the lowest setting which is still higher than the expected voltage. If 115 VAC is expected and the meter has 10 VAC, 50 VAC, 250 VAC and 1000 VAC scales, turn the dial to 250 VAC. Some meters have only one VAC choice and the meter can automatically adjust for the voltage received (auto scaling). ## CHECKING MOTOR CURRENT A clamp-on meter is recommended for testing the motor current. These meters work by detecting the magnetic field surrounding a conductor so a high motor current does not pass through the meter. Ensure that when a generic multi-meter is testing current, the leads are placed in series with the current and not in parallel. Otherwise, the meter’s internal fuse will blow or will be damaged. In addition, the motor current may exceed the maximum current allowed by the meter’s specification, resulting in a blown meter fuse or damage to the internal circuitry. ## TESTING CAPACITANCE Ensure the meter has the means to test for the capacitance needed to check alternating current motor capacitors. Refer to the operator manual for the meter to learn about this feature. 3 ## Page 5 # BASIC TROUBLESHOOTING # TRANSFORMERS Transformers are used to change incoming voltage to a different outgoing voltage. A transformer has a primary side (incoming voltage) and a secondary side (outgoing voltage). The primary side connects to wires from the main power source and the secondary side outputs the transformed voltage. In commercial gate operators, the secondary side is generally 24 Vac. Read the markings on the transformer to determine the primary and secondary voltages. Transformers are rated in VOLT Amps (VA). A transformer can only pass the rated amount of electricity from the main power to the secondary side. Be careful not to overload the transformer. Verify the amperage rating on all devices connected to the 24 Vac side of the transformer including devices attached to the control board. Multiply the Amperage rating for each device by the voltage needed to run the device. > Figure: Drawing of a block transformer with mounting tab and six spade terminals. Labels: “24 Vac” at the two left terminals; “COM,” “120,” and “240” at the right terminals. Caption: “(Example: Block Transformer)”. ### EXAMPLE FOR CALCULATING AMPERAGE DRAW Below is an example of text for a label that could be placed on accessory devices: Output Rating…5 AMPS 28VAC or DC Max Power…24VAC @ 30ma The “Power” rating is required. The transformer’s secondary side is 24 VAC and the transformer is rated for 20VA. The example accessory above uses 30 milli-amps, which is .03 Amps. Multiply the volts being used (24V) and the amps (.03A) to get the VOLT Amps (VA) used by the accessory (24Vx0.03A=0.72VA). That leaves (20-0.72=) 19.28VA left for other accessories (photoelectric sensors, loop detectors, etc). Once the total VA exceeds 20VA, the operator may experience failures. For operator setups requiring multiple accessories, calculate total VA draw and upgrade the transformer if necessary (40VA transformers or greater are available). The output rating is how much electricity the accessory is able to have pass through it. This number is useful when determining if an accessory will properly function long term with the operator. The output rating has nothing to do with the required amount of electricity to make the accessory function. | TYPE OF TRANSFORMERS | MODELS | |---|---| | Plug-in Transformer | LA400UL, RSL12UL, RSW12UL | | Toroid Transformer | LA500UL, CSL24UL, CSW24UL, HD OPERATORS | | Block Transformer | CSW200UL, SL3000UL, SL585UL, SL595UL | ## Page 6 # BASIC TROUBLESHOOTING # RELAYS ## EXPANSION BOARD RELAYS In gate operators, relays are commonly used to control operator functions or activate/deactivate ancillary devices such as heaters or lights. When electricity is applied to a relay coil, it energizes a magnetic field that will close a Normally Open switch or open a Normally Closed switch. A relay typically has prongs labeled COM, NO, NC, and two prongs to power the relay coil. Relays are available with different coil voltages and contact options. The auxiliary relays are single pole, double throw. A pole is another name for a switch. Double pole is two separate switches being turned on or off by the same activation coil (two separate Comms, NCs and NOs). Double throw means there are two positions for the output (NO and NC). The 2 Auxiliary Relays on the expansion board can be set to activate in different conditions based on how you set the 3 switches for each relay. They can be set to activate any time the gate is open or closed or when the gate is in motion. In one setting you can trip the relay 3 seconds before the gate begins to move and while the gate is in motion. You can set the relay to activate if the gate is forced off the closed limit position. One setting for Aux Relay 1 uses the LEDs for the Open, Close, and Stop inputs to display how many cycles (to the nearest 100) the operator has performed. The Auxiliary relays can also be used in conjunction with a barrier arm operator for the Sequenced Access Management System (SAMS) or tandem function. See the operator’s manual for a list of all the available functions. ### RELAYS ON THE EXPANSION BOARD > Figure: Diagram of an expansion board. Three terminal blocks at left are labeled J3 “(FAIL SAFE) SHADOW,” J4 “(FAIL SAFE) INTERRUPT,” and J5 “(FAIL PER SWITCH) EXIT.” The central area shows AUX RELAY 1 and AUX RELAY 2, each with numbered switch positions and relay terminals labeled “NO COM NC.” A black oval highlights the auxiliary relay switch and terminal area. Other readable labels include “QUICK CLOSE,” “AC FAIL,” “EXIT FAIL,” “ANTI TAIL,” “POWER,” “TO MAIN BOARD,” “CLOSE,” “SBC,” “OPN,” “CLS,” “STP,” and “COM.” ### RELAY WIRING EXAMPLE > Figure: Wiring diagram showing two relay terminal blocks, each labeled “NO COM NC,” connected to a Traffic Light and a Class 2 Power Source. The power source label reads “Class 2 Power Source (42 Vdc [34 Vac], 5 A maximum).” Red and black wires are shown, with red “+” and black “−” polarity markings. The traffic light has red and green lamps. # EXPANSION BOARD SWITCH SETTINGS - The Quick Close feature allows the gate to close without having to travel to the full open position. When active, the operator monitors the Interrupt Loop and Close Eyes inputs and once the vehicle clears these devices the gate will reverse and Close. - When the AC Fail Open switch is selected, the operator will move the gate to the Open position if AC Power is lost. There is a 30-second delay before the gate opens after the loss of primary AC power. If the switch is set for the Battery option, the operator will run on the battery until the battery drops below a certain voltage. At that point, the gate will either open or close depending on how you set the Low Battery switch on the main control board. **NOTE:** The AC Fail Open switch is not functional for AC operators. - The Exit Fail switch sets the operator to either open or remain closed in the event of an internal detector failure (loop short or open). - The Anti-Tailgate switch alters the way the Interrupt Loop affects gate operation. When the switch is on, the gate pauses if the gate is closing and the interrupt loop is activated. The gate will stay paused until the vehicles backs off the loop, then continue closing. > Figure: Expansion board illustration with a black oval around lower switch settings and relay terminals. Labels in the circled area include “QUICK CLOSE,” “AC FAIL,” “EXIT FAIL,” “ANTI TAIL,” “ON,” “OFF,” “OPEN,” “BATT,” “CLOSE,” and “NO COM NC.” ## Page 7 # BASIC TROUBLESHOOTING > Figure: Warning banner with electrical hazard symbol and text “WARNING.” Below: “To protect against fire and electrocution:” and bullet “DISCONNECT power (AC or solar and battery) BEFORE installing or servicing operator.” # CAPACITOR (FOR AC OPERATORS) **SYMPTOM:** A bad capacitor will cause a motor to hum when trying to run, or stall while it is running. ## CHECK THE CAPACITOR: > Figure: Step 1 photograph of a circuit breaker panel with a hand switching a breaker. Red numbered circle: “1.” Caption: “Disconnect ALL power from operator.” > Figure: Step 2 photograph of a person using a screwdriver across capacitor terminals above a motor. Red numbered circle: “2.” Text: “IMPORTANT: Discharge the capacitor BEFORE touching it!” “Discharge the capacitor by touching a screwdriver across the capacitor terminals (make sure to hold the insulated end of the screwdriver when doing this). You may see a small spark when discharging the capacitor, this is normal.” “Visually inspect the capacitor for any burn marks, bubbling or oil leakage. This is a good indication of a bad capacitor.” > Figure: Step 3 photograph of a multimeter measuring a capacitor. Red numbered circle: “3.” Meter display reads “7.48.” Text: “Using a multi-meter, measure the capacitance between the capacitor contacts. The measurement on the meter should be within the uF rating on the label.” “The meter must be capable of making capacitance measurements. See the meter’s operator manual for more information.” **SOLUTION:** If the capacitor measures outside of 20% of rated capacitance, it should be replaced. ## Page 8 # BASIC TROUBLESHOOTING > Figure: Warning banner with electrical hazard symbol and text “WARNING.” Below: “To protect against fire and electrocution:” and bullet “DISCONNECT power (AC or solar and battery) BEFORE installing or servicing operator.” # BRUSHED DC MOTORS **SYMPTOM:** The motor will not run. ## CHECK THE MOTOR: Disconnect ALL power from operator.

Internet Gateway d. Internet Gateway serial number (located on the bottom of the Internet Gateway) e. MyQ-Enabled Gate Operator **What is an Internet Gateway?** The Internet Gateway (828LM), is a 900 MHz Internet Protocol device for monitoring and controlling MyQ devices (e.g. gate operator or light control). **Does an Internet Protocol Address or Dynamic Host Configuration Protocol need to be established for the Internet Gateway?** Yes, the Internet Gateway (828LM) requires a Dynamic Host Configuration Protocol (DHCP). **What is the required speed of the Ethernet port for the Internet Gateway?** The Internet Gateway has a minimum speed of 10 Mb/s. **How does the Internet Gateway connect to an existing residential or commercial network?** The Internet Gateway needs to be connected to a Local Area Network port on a network router or network switch, establishing connection to the Internet. When the Internet Gateway connects to the Internet, a secure session is established with the MyQ server. **Can the Internet Gateway be pinged to verify connection to a network?** The Internet Gateway does not support a ping response. **Can a static IP address be established on the Internet Gateway?** A static IP address cannot be established on this device. The Internet Gateway requires the router/Dynamic Host Configuration Protocol (DHCP) to provide a Local Area Network (LAN) Internet Protocol (IP) address. **How can the Internet Gateway be tested from the Internet?** To test the Internet Gateway from the Internet, do either of the following: a. Add the Internet Gateway to a MyQ account. If the Internet Gateway is already on a MyQ account, add a MyQ-Enabled device (e.g. gate operator or light control) to the MyQ account. b. If a MyQ-Enabled device is already on the MyQ account, provide a command (open/close, on/off) using the MyQ app. # FREQUENTLY ASKED QUESTIONS **Can the Internet Gateway be connected from a remote location using the Wide Area Network (WAN) to our corporate offices and access the Internet from the corporate location?** ## Page 30 MyQ® If the Internet Gateway is successfully connected to the MyQ® server (green LED on MyQ Gateway is illuminated and solid), the MyQ app can monitor and control a MyQ device from any location. All MyQ-Enabled devices must be on the MyQ account and be within transmitting capability of the Internet Gateway. **Are communications to/from the Internet Gateway encrypted?** The Internet Gateway uses AES-128 encryption for all communications through the Internet. The Internet Gateway uses proprietary data encryption over 900 MHz to/from MyQ devices. **How can the MAC address of the Internet Gateway be obtained?** To obtain the MAC address, connect the Internet Gateway to a network router and use a computer to login into the router and locate the MAC address within the connected devices list. A MAC address for an Internet Gateway should be in the following format: 64:52:99: XX: XX: XX. **How to put a MyQ Gate Operator into programming/learn mode:** Press the learn button twice on the primary operator (the operator will beep as it enters learn mode). The Internet Gateway will pair to the gate operator if it is within range, and the gate operator will beep again if programming is successful. **How to use the RESET button to put a MyQ Gate Operator into programming / learn mode when the gate is closed:** 1. Ensure the gate is closed. 2. Give the gate operator an OPEN command. 3. Within 30 seconds, when the gate is at the open limit, press and release the RESET button 3 times (on the primary gate) to put the primary operator into high band learn mode (the gate operator will beep as it enters learn mode). 4. The Internet Gateway will pair to the gate operator if it is within range and the gate operator will beep again if programming is successful. 5. The status as shown by the Internet Gateway app will be either “open” or “closed”. The gate operator can then be controlled through the Internet Gateway app. ## Page 31 MyQ® # TROUBLESHOOTING MyQ® If issues are experienced when adding an Internet Gateway, a LiftMaster Gate Operator or light control to a MyQ® account, please review the troubleshooting topics below. # CONNECTION ISSUES **PROBLEM** If the green LED on the Internet Gateway is not illuminated or blinking, the Internet Gateway is not connected to the Internet. **SOLUTION** There are a few different reasons an Internet Gateway will not successfully connect to the Internet: - An incompatible router - A router configuration setting (e.g. MAC address filtering) - A network security appliance (firewall) **PROBLEM** Green LED on the Internet Gateway is off. The router or network switch is not providing an IP address to the Internet Gateway. **SOLUTION** - Verify power to the Internet Gateway. Disconnect and reconnect power to the Internet Gateway. The blue and green LEDs should blink on and off a few times when the Internet Gateway is initially powered. - Check the Ethernet cable connections between the Internet Gateway, router, or network switch. - Confirm the router or network switch is providing a connection to the Internet. - Check if the router or switch is incompatible with the Internet Gateway. Go to LiftMaster.com/MyQ-PAS and look for the Incompatible Router and Switch section. - Connect the Internet Gateway to a different LAN port on the router or network switch. Determine if a router setting is preventing the Internet Gateway from obtaining an IP address (e.g. MAC address filtering, firewall settings). - Review the router’s settings and manual. - Router must be set to DHCP to provide an IP address to the Internet Gateway. - The Internet Gateway requires TCP Port 8883. Verify that it is open on external or internal firewalls. Reset the router. Disconnect power to the router for 30 seconds. Reconnect power to the router. Wait up to 5 minutes after the router is active to determine if the green LED on the Internet Gateway is illuminated solid or blinking. **PROBLEM** Green LED on the Internet Gateway is blinking. If the green LED on the Internet Gateway is blinking, the Internet Gateway has obtained an IP address from the router, but the Internet Gateway is not connecting to the MyQ® server. **SOLUTION** Determine if a router setting (e.g. firewall setting) is preventing the Internet Gateway from communicating with the Internet. - Review the router’s settings and manual. - The Internet Gateway requires UDP port 80 to have a UDP timeout of 180 seconds or greater. Determine if a network security appliance (firewall, e.g. SonicWALL®, ZyWall) is installed. - Determine if the network security settings are preventing connection of the Internet Gateway to the Internet. - The Internet Gateway requires UDP port 80 to have a UDP timeout of 180 seconds or greater. SonicWALL’s UDP timeout must be adjusted to be 180 seconds or longer for both inbound and outbound data traffic. See SonicWALL Fire Wall section for more information. ## Page 32 MyQ® # MyQ® ACCOUNT ISSUES **Unable to add more than one MyQ device to a MyQ account:** - Prior to adding MyQ devices, an account must be established. An account can be created by downloading the MyQ app from a smartphone or tablet app store. - Up to sixteen MyQ devices may be added to one Internet Gateway (828LM). If more than sixteen MyQ devices are required, additional Internet Gateways can be installed and added to the same MyQ account. For optimal performance of MyQ, the maximum number of devices added per account should not exceed 32. - MyQ provides the ability to monitor and control MyQ-Enabled Gate Operators at more than one location from the same account. To monitor and control MyQ-Enabled Gate Operators at more than one location, additional Internet Gateways will be required at each location. - An illuminated blue LED will be solid on an Internet Gateway when one or more MyQ devices (gate operator or light control) are paired to an Internet Gateway. The blue LED will not illuminate if no MyQ devices are paired to the Internet Gateway. **NOTE:** A MyQ device can only be associated (added) to one MyQ account. **If a MyQ device fails to add to a MyQ account, please review the troubleshooting steps below:** If a pop-up error message appears on the MyQ app when attempting to add a device, verify the MyQ device is not already associated with another MyQ account. If the “add device” process times out after three minutes, the MyQ device may not be in the programming/learn mode or may be out of range of the Internet Gateway. Sample error message that may be encountered: No response, gate operator is not responding. Please try again later. **PROBLEM** Unable to add a MyQ-Enabled Gate Operator to a MyQ account. **SOLUTION** - Confirm the Internet Gateway is powered and the green LED illuminated and solid. - Confirm the Internet Gateway is added to the MyQ account. - Confirm the MyQ-Enabled Gate Operator is in the programming/learn mode. - Confirm the signal from the Internet Gateway can reach the MyQ-Enabled Gate Operator. Depending upon obstructions, the average range from the Internet Gateway is between 300 to 600 feet. Are there too many walls between the Internet Gateway and the gate operator? To test a MyQ-Enabled Gate Operator, program a remote control to the operator and stand near the Internet Gateway. Test if a remote control can operate the MyQ-Enabled Gate Operator. If necessary, relocate the Internet Gateway closer to the MyQ-Enabled Gate Operator using a longer CAT5 cable or higher quality Ethernet cable (up to 100 feet). - Confirm the antenna is installed on the gate operator. The antenna is included inside a poly bag on the gate operator cover along with the installation manual, user guide and quick start guide. - MyQ-Enabled devices communicate using a 900 MHz radio signal. Electronic devices in the same area of the Internet Gateway or MyQ devices may create a range issue. Some troubleshooting options include powering down or relocating other 900 MHz products (900 MHz cordless phone, etc.) in the area of the MyQ device causing the interference. ## Page 33 MyQ® # MyQ® ACCOUNT ISSUES **PROBLEM** The MyQ-Enabled Gate Operator will not respond to the app. **SOLUTION** - Confirm the green LED on the Internet Gateway is illuminated and solid. If the green LED is not illuminated or blinking, see Connection Issues section. - For a MyQ-Enabled Gate Operator, confirm that the operator is powered up and fully operational. Control the MyQ-Enabled Gate Operator from a remote control. - Confirm the MyQ-Enabled Gate Operator has been added to the MyQ account (a gate operator image should be present on the Places screen of the app). - Confirm the signal from the Internet Gateway can reach the MyQ-Enabled Gate Operator.

A hub or switch may resolve this situation, but is not a verified fix. ## INCOMPATIBLE NETWORK SWITCH When installing an Internet Gateway, an identified issue has been associated with the following network switch: | MANUFACTURER | MODEL | |---|---| | TRENDnet | 5-Port-10/100Mbps TE100-S5 | ## SONICWALL® FIRE WALL **PROBLEM** The performance issues listed below are caused by SonicWALL’s factory default UDP connection timer being set to 30 seconds, which closes the Internet Gateway connection to the server after the Internet Gateway enters its sleep state and reduces its communication to the server to once every 60 seconds. When this occurs, the Internet Gateway will take up to 2 minutes to recognize connection to the server is lost before having to re-establish connection. This process will continue to repeat. When a MyQ® device is behind a SonicWALL Network Appliance, the following MyQ app performance issues may occur: - Difficulty controlling a MyQ device through the MyQ app. - Manual operation by a MyQ device may not change status on the MyQ app (gate operator is closed by pressing the remote control, but app shows gate open). - Upon power cycling of an Internet Gateway, the app will work for a brief period of time and then enter a non-working state. **SOLUTION** The SonicWALL UDP Connection timer should be changed to 120 seconds or greater. LiftMaster® recommends a minimum value of 180 seconds. The timer must be changed in multiple locations. - The default UDP timer should be changed, which will change the UDP connection timer for any new rule made to the SonicWALL. - Any current LAN -> WAN rules must have the UDP connection timeout updated manually. Set “Default UDP Connection Timeout (seconds):” to “360” and set “UDP Connection Inactivity Timeout (seconds):” to “360”. 35 ## Page 37 ## Page 38 ## Page 39 ## Page 40 LiftMaster 300 Windsor Drive Oak Brook, IL 60523 LiftMaster.com 114-5965-000 © 2023 LiftMaster – All Rights Reserved
