BEFORE YOU BEGIN

2016 UL COMPLIANT GATE OPERATORS

New UL 325 standards for vehicular gate operators go into effect in January of 2016. The new standard will require gate operators to monitor for fault conditions of external entrapment devices. 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 (model LMRRU).

These operators contain an inherent (internal) entrapment protection system and REQUIRE the addition of an external monitored entrapment protection system (non-contact photoelectric sensor or contact edge sensor) for EACH entrapment zone prior to gate movement. A monitored device sends a

pulsed signal to the operator so the operator is aware of the device. If the operator does not receive the signal from the device it will not run.

An entrapment zone is every location or point of contact where a person can become entrapped between a moving gate and a stationary object. Your application may contain one or many entrapment zones. Property owners are obligated to test entrapment protection devices monthly. Use only LiftMaster

approved entrapment protection devices.

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.

CHECKING OHMS/CONTINUITY

When checking the operation of a switch, select the ohm mode on multimeter. (The ohm symbol is 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. The wires 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, 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).

). Make sure the test leads are plugged into the correct sockets for reading

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 new voltage created. 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.

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.

BASIC TROUBLESHOOTING

RELAYS

EXPANSION BOARD RELAYS

In gate operators, relays are often used to either control certain operator functions or activate/deactivate ancillary devices such as heaters or lights. When electricity is applied to a relay coil, it energizes a magnet and will close a Normally Open switch or open a Normally Closed switch. A relay typically has prongs labeled COMM , NO, NC, and two prongs to power the relay coil. Relays are available with different coil voltages and contact options. LiftMaster’s line of gate operators primarily use double pole/double throw relays. 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 1000) the operator has performed. The Auxiliary relays can also be used in conjunction with a barrier arm operator for the SAMS or tandem function.

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. 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.

BASIC TROUBLESHOOTING

To protect against fire and electrocution:

• 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:

Disconnect ALL power from operator.

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.

SOLUTION: If the capacitor measures less than 90% of the rating, it should be replaced.

Using a multi-meter, measure the capacitance between the capacitor contacts. The measurement on the meter should be within 10% of the uF rating on the label.

SOLAR TROUBLESHOOTING

SYMPTOM

The operator alarm will beep three times with a command and the BATT LOW LED will be on when the solar panel is not charging the battery.

SOLUTIONS

• Check that the correct number of solar panels are connected to the operator. 12V operators require one 10W 12V panel up to a maximum of three 10W 12V panels. 24V operators require two 10W 12V panels up to a maximum of six 10W 12V panels.

• Check that the correct batteries are used for the application.

• Check that the whole panel(s) is facing south within 150 feet of the operator and receiving full sunlight. Make sure the solar panels are not in the shade.

• Check that the accessories are not drawing too much current. Use LiftMaster low current draw accessories.

• Check that the number of gate cycles does not exceed the cycle ratings for the operator and application.

• Check that the number of gates cycles corresponds with the solar zones (see below). Refer to your gate operator manual for specific gate cycles.

a. Router

b. Internet connection

c. 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 (DCHP).

What is the required speed of the Ethernet port for the Internet Gateway?

The Internet Gateway is a 10 Mb/s device.

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.

What Transmission Control Protocol (TCP) and/or User Datagram Protocol (UDP) ports need to be opened in our firewall?

The Internet Gateway uses User Datagram Protocol (UDP) port 80 for inbound and outbound data messages and uses Transmission Control Protocol (TCP) port 2165 for firmware updates. If a firewall or network security appliance is on the network (e.g. SonicWALL (UDP) Timeout setting needs to be set to 180 seconds or greater. See the Incompatible Router and Switch section for more information.

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 (DCHP) 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

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 UDP port 80 to have a UDP timeout of 180 seconds or greater.

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

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

• 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.

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 visiting MyLiftMaster.com or 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.

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

• 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 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”.
