Basic Troubleshooting

Always Follow Local Electrical Codes

WARNING! If you are not trained in electrical safety, contact a professional electrical safety trainer. It is in your best interest to have electrical safety training. Do not attempt to work on a powered (turned on) operator if you have not received electrical safety training. Remember, it is dangerous to deal with high-voltage electricity. Many people incurred serious injuries, including fatalities, as a result of electrical accidents. You must be very careful when checking line voltages.

The high-voltage wiring to the operator, low-voltage wiring to the control station(s), and safety devices may require a licensed electrician for installation.

Make Sure The Door Is Working Properly

Close the door and disconnect the door from the operator. Manually operate the door. The lifting force needed by most doors should be manageable by one person and the door should move smoothly. Check all hardware for wear, binding and tightness. Replace any marginal parts. The door should be in good working order. An unbalanced or jerking door will put excess wear on the operator and cause premature failure. When checking a door with a hoist operator, be sure the door is disconnected from the operator and lifted by hand and not by the hoist/hand chain. It is very difﬁ cult to determine if the door is balanced when using the operator chain hoist. Repair any door problems before reattaching the operator.

Remove All Accessories And Control Devices

In many cases an operator may be malfunctioning due to accessories or control devices attached to the operator’s control circuit. The ﬁ rst step in troubleshooting is to use a process of elimination. Disconnect all wired accessories and control devices. Many times in complicated installations, there will be extra devices installed by an electrician or other subcontractor that may not be functioning properly with the operator. If the door functions properly after disconnecting additional devices, start reconnecting each device one at a time. Determine if any of the control device(s) are causing the problem. Advise the customer of your ﬁ ndings and their options for repairs/replacements.

NOTE: When monitored entrapment protection devices are removed from operators that require a monitored entrapment protection device such as photo eyes; they will no longer function unless they are under constant pressure.

Basic Troubleshooting

Check Incoming Voltage

Check the incoming power voltage to ensure readings are within 10% of the rated voltage. For example, a 115VACrated power line should read between 103.5 to 126.5VAC. Continue to monitor voltage as the operator is activated through one cycle. Voltage drops occur, but should not drop more than 5% under load from the non-functioning position, +/- 10% at startup and +/- 5% while the operator is running. Low voltages can cause damage to components and cause functionality issues.

NOTE: The installation of a dedicated circuit is required for achieving optimal voltage.

Check The Overload

Look at the overload button (when present) on the outside or inside of the electrical box. To conﬁ rm if the overload has been tripped, press the overload button. If the overload has been tripped, look for a short or bad wire in the operator. Resetting the overload will only ﬁ x the problem temporarily. LiftMaster recommends the cause of the overload be identiﬁ ed and resolved. Logic operators are equipped with a thermal overload and will automatically reset themselves. After the operator cools it must be run a full cycle.

Check Any Interlock Switches

Check any interlock and/or disconnect switches for full activation. Manually activate any interlock switches to verify proper motion of the switch and use a multimeter across the switch leads to verify proper electrical output. The output should show a closed circuit (low resistance) when the door is ready to be activated.

All of the above testing is generic for Logic 3.0, Logic 4.0, Logic 5.0, Medium Duty Logic and Mechanical operators. Mechanical operators are also known as Contactor or Electro-Mechanical operators. Efﬁ ciency in troubleshooting operators differs from this point. Logic operators have many LEDs and special controls to speed up diagnosis. For a Mechanical operator, refer to Section C. For Logic 3.0, 4.0, 5.0 operators, continue on to Section B.

Look For Green “POWER” LED

The Industrial Duty Logic Operator has many features reducing time required to identify and make repairs, as well as time spent training service technicians. Please note when working on an operator, always follow proper electrical safety guidelines and local codes.

The transformer should produce 24VAC (±10 %) on the secondary side. If the green power LED, which is located near terminal 13, is illuminated then 24VAC is present on the logic board. Verifying with a multimeter is still recommended. To check the secondary side of the transformer, set the meter to volts AC and check across the yellow and blue wires on the transformer or terminals 13 and 14 on the logic board. If working properly, they should each show 24VAC +/10%.

The logic board and all the controls are run on 5VDC. The 5VDC control signal allows 1000 ft. control runs with 18AWG wire. Be sure any incoming signal to the board is from a dry contact and not a voltage source. A dry contact, such as a standard switch, is a device connecting two wire leads to make a closed circuit. Some examples are the open or close buttons on LiftMaster’s standard 3-button control station, limit switches and standard relay outputs.

If the green “POWER” LED does not turn on, the transformer may not be working correctly. Verify primary voltage feeding the transformer by checking: Logic 3.0 and Logic 4.0 - White and Brown wires. Logic 5.0 - Common and appropriate wire. See the chart for high voltage wires.

Check Control Station

Verify the control stations are wired to the terminal strip correctly. This is easily checked by using the “OPEN,” “CLOSE”, and “STOP” LED diagnostic LEDs. The operator should have the “OPEN” and “CLOSE” LEDs off and the green “STOP” LED on.

Turn the selector dial to DIAG to put the operator in diagnostic mode. Conﬁ rm the wiring is correct on the board by pressing the “OPEN” and “CLOSE” button on the board separately. When each button is pressed, the corresponding LED should turn on. When working properly, the STOP LED should be illuminated. Pressing the STOP button should make this LED turn off. If the LED’s respond accordingly to the on-board OPEN/CLOSE/STOP buttons, test the 3-button control station or the wiring to the 3-button control station.

To test the 3-button control station, open the control station and use a multimeter to verify continuity. When working properly, an idle 3-button control station with no depressed buttons should read inﬁ nite resistance (open circuit) across the “OPEN” and “CLOSE” buttons and 0 Ohms (closed circuit) across the “STOP” button. The meter should read 0 Ohms (closed circuit) when the “OPEN” and “CLOSE” buttons are pressed, and inﬁ nite resistance (open circuit) when the “STOP” button is pressed. If the continuity test on the 3-button control station yields different results than listed, the control station will have to be replaced.

NOTE: Don’t run control wiring and power wiring in the same conduit, these wirings should be separated by 18”.

Troubleshooting

Check Control Station (Continued)

Terminals 2 and 3 are also a normally closed circuit used when an external interlock is present. If the external interlock is activated the “STOP” LED will not be lit.

If the LEDs do not respond, disconnect the wall control station(s), put a jumper between the “STOP” and “COMMON” terminals, and try activating the LEDs by pressing the on-board 3-button control station next to the terminal strip. If the LEDs do not respond, there is a problem with the logic board and will require replacement.

If the lights do respond, but the operator still does not run, reset the operator to factory defaults.

Industrial Duty Logic Operators

Resetting Factory Defaults - Clearing Memory

To reset most of the user installed settings back to factory defaults:

1) Turn the selector dial to DIAGNOSTIC.

2) Press and hold the STOP button for 5 seconds. The MAS LED will ﬂ ash

momentarily when the factory defaults have been restored.

3) Return the selector dial to the desired wiring type.

Factory Defaults:

a) Timer-To-Close is set to 0 seconds. b) The Mid Stop is deactivated. c) The Maintenance Alert System is deactivated. d) The Maximum Run Timer is set to 90 seconds. e) Car Dealer Mode is deactivated. f ) The remote controls and myQ® devices will still be learned. g) Remote control programming via the 3-button control station. h) The LiftMaster Monitored Entrapment Protection (LMEP) device(s) will

be unprogrammed.

NOTE: Life of Operator feature (Odometer/Cycle Counter) and programmed remote controls and myQ devices are not cleared.

Selected Features

Car Dealer Mode

Feature: The car dealer mode uses the SBC (Single Button Control input)

to bring the door from a closed position to the programmed Open Mid-Stop position and keep it at that location even with multiple inputs.

Beneﬁ t: Provides energy cost savings by limiting the door opening height. Requirements: This feature works in conjunction with the programmable

Timer-To-Close feature. To enable this feature you must ﬁ rst connect a treadle, photoelectric sensor or loop detector accessory to the SBC input and must have at least one LiftMaster Monitored Entrapment Protection (LMEP) device installed (refer to the installation manual). Wiring type must be set to TS or T.

TO PROGRAM:

1) Start with the door in the closed position.

2) Turn the SELECTOR DIAL to PROG.

3) Push the TTC button and release (Green Timer LED will

be lit).

4) Push the MID button and release. This turns on the Car Dealer Mode.

(The Green Timer LED will ﬂ ash 6 times indicating the Car Dealer Mode is turned on.)

5) Push the TTC button and release.

6) Turn the SELECTOR DIAL to the desired wiring type (TS or T).

NOTE: To disable the Dealer Mode follow steps 2 and 3, then press the MRT button and release. (The Green Timer LED will ﬂ ash 3 times indicating that the Car Dealer Mode is off.)

Operation will vary depending on wiring type

Life Of Operator (Odometer/Cycle Counter)

The operator is equipped with an odometer to show how many months and cycles the operator has performed from the time it was installed. This feature can help determine how long the operator has been in service.

1) Start with the door in the closed position.

2) Turn the SELECTOR DIAL to DIAG (diagnostic mode).

3) Press and release the MAS button on the logic board.

4) Press and release the MRT button on the logic board.

5) The open and close lights will ﬂ ash. OPEN for every 5,000 cycles and CLOSE for every 3 months.

6) Return the SELECTOR DIAL to the desired wiring type.

NOTE: If operator has not reached 5,000 cycles or 3 months, there will be no indications.

Thermal Overload

The Logic operators have been equipped with a thermal motor overload. The thermal overload has replaced the need for a manual overload on the operator electrical box. The thermal overload works by shutting down the operator until the operator can cool off and reset automatically. After the overload resets, the operator must be cycled with constant pressure. The operator must be opened and closed fully to reset the operator to normal operation. This feature saves the installer from having to physically reset the operator manually.

Motor Direction Jumper

This feature is designed to save the installer from having to rewire the limit switches and motor when unique applications require reversing the open and close limits. This would typically be seen on an auxiliary trolley modiﬁ cation, through-wall application, or when mounting the operator upside down. By removing the jumper from the motor direction pins, the door can be set to either a standard or reversed direction. The factory default is the standard direction. The logic board automatically changes the motor direction and reverses the Open Limit Switch (OLS) and the Close Limit Switch (CLS). The only limit switch requiring movement is the Sensing Limit Switch (SLS) to the close side of the operator. This feature is provided for ease of install.

NOTE: Not for use when a 3PH operator is reverse phased, for 3PH two of the incoming legs of power should be reversed.

Diagnostic Chart

The industrial duty logic boards (5.0, 4.0, 3.0) have several LEDs to assist in the installation and troubleshooting of the operator. The following chart should assist in verifying the operator is functioning properly. Turn the selector dial to DIAGNOSTIC to keep the door from moving while troubleshooting.

Error Codes

LiftMaster Logic 3.0, 4.0, and 5.0 Operators incorporate a self-diagnostic feature built into the MAS LED. In addition to indicating when routine maintenance is due, the MAS LED can be used to troubleshoot problems with the operator.

If the MAS LED on the logic board or 3-button control station is ﬂ ashing on and off rapidly, the Maintenance Alert System has been triggered and service is due on the operator. If the MAS LED ﬂ ashes 2 or more times in a row followed by a pause, an operator error has occurred. To view the errors, turn the selector dial to DIAGNOSTIC and press the OPEN button. To view the individual error codes (if more than one exists) press CLOSE. It is possible to have more than one error at a time. Use the chart below to determine the error.

Basic Electrical Circuit

A basic electrical circuit is made up of one continuous electrically conductive loop. As an example, see the wiring diagram of a typical ﬂ ashlight to the right.

Electricity ﬂ ows from positive (+) to negative (-). The switch stops the electricity from ﬂ owing.

When the switch is closed, electricity will ﬂ ow in a continuous loop and make the bulb light up. The electricity will ﬂ ow from the positive side of the battery past the closed switch through the light bulb (providing the electricity to light the bulb) and return to the negative side of the battery.

When the switch is open, the electricity cannot pass through and electrical ﬂ ow is stopped.

There are many types of switches and components available within an electrical circuit. Examples include: motors, contactors, relays, interlocks, capacitors and limit switches of various types. For commercial operators to function, each component must be working correctly for the electrical ﬂ ow to pass through and form a continuous electrical circuit or loop.

Limit Switches

Basic Electrical Information

Activation Arm

Press this lever down to activate the switch

Three prongs are present on a limit switch. They are labeled Common or “Com”; Normally Open, abbreviated NO; and Normally Closed, abbreviated NC. Below is a wire diagram of a limit switch.

When no pressure is applied to the limit switch activation arm, electricity will ﬂ ow from the Common prong to the Normally Closed prong.

Normally Open

Common

Normally Closed

Activation arm IS NOT being pushed

Normally Closed

When the activation arm is pressed, electricity will ﬂ ow from the Common Prong to the Normally Open Prong. Electricity will never travel from the NO prong to the NC prong.

Normally Open

Common

Normally Closed

Activation arm IS being pushed

The word “NORMALLY” generally refers to the action of the switch when nothing is activating it. “Normally Closed” is a continuous ﬂ ow of electricity when the switch is not activated, establishing a closed circuit. “Normally Open” is a non-continuous ﬂ ow (no ﬂ ow) of electricity when the switch is not activated, establishing an open circuit.

Multimeter

When shopping for a meter, look for a meter able to ﬁ t 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 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.

Basic Electrical Information

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 ﬂ owing from the Common prong to the Normally Closed prong. This demonstrates continuity. Activate the switch, the meter will read inﬁ nite 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 ﬂ ow 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. 115VAC, 460VAC and so on. 24VAC is also found in the control circuit of a commercial 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 115VAC is expected and the meter has 10VAC, 50VAC, 250VAC and 1000VAC, turn the dial to 250VAC. Some meters have only one VAC choice and the meter can automatically adjust for the voltage received (auto scaling).

Relays

In commercial 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. See the light circuit example below containing a relay.

The diagram below shows two different batteries supplying different voltages. The relay separates the electricity so the different components are able to work together. Commercial door operators work in a similar fashion. Relays make it possible for high voltage to work with low voltage.

Basic Electrical Information

12V 24V

When the NO switch is pressed closed, electricity will travel through the relay coil and activate the relay. The relay switch will allow electricity to ﬂ ow through the circuit and turn on the light.

Relays

Relays are available with different coil voltages and contact options. LiftMaster’s line of commercial operators primarily use Double Pole/Double Throw Relays. 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). When shopping for relays, Triple Pole/Single Throw and Single Pole/Double Throw and many other options are available. Relays are rated with speciﬁ c amp and voltage ratings. Always replace a relay with the same ratings.

When looking at a wiring schematic, relays will be drawn with several components and the name of the relay will be noted.

Basic Electrical Information

The Coil The NC ContactsThe NO Contacts

Here is the same relay light switch shown as a wiring schematic.

NO Switch

AC Power Source

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 door operators, the secondary side is generally 24VAC. 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 24VAC side of the transformer including devices attached to the logic board. Multiply the Amperage rating for each device by the voltage needed to run the device.

Transformers

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 24VAC 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 (photo-eyes, 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 commercial operator. The output rating has nothing to do with the required amount of electricity to make the accessory function.

LiftMaster does offer technical training courses. See the back of this guide or visit liftmastertraining.com for more information.

Suggested Service Truck Supplies

The items listed below are intended for repair of a LiftMaster operator and not necessarily for repair of a door.

MULTIMETER - Look for a meter that has an audio signal for continuity. To make working on a ladder safer and easier, look for test leads able to grip onto the wire being tested. A high quality (expensive) multimeter is not required. A less expensive meter will work very well for diagnosing electrical issues within an operator.

SCREWDRIVERS - Standard size Phillips and Flathead and a small size Flathead for setting DIP switches and working with Logic “Daughter Boards” i.e. CPS3CARD, TLS1CARD, etc. Screwdrivers should be insulated.

SOCKETS AND CRESCENT WRENCHES - A 1/4” nut driver will be extremely handy. Crescent Wrenches and Socket Sets are mainly for removing an operator from the door, wall or ceiling.

Additional Items:

Wire Stripper w/Crimping Tool Wire Cutters Needle Nose Pliers Standard Pliers Manual Winch - Used for lifting or lowering the operator safely Jumper Wires w/Alligator Clips

MECHANICAL LOGIC

Control Wire Distance

Main Power Wire Gauge And Length Recommendations

A power drop between idle (off) and running voltage should not exceed 2 volts.

Understand the amperage rating for each operator’s voltage and horsepower using Table 1. The information in the table may change without notice; review the instruction manual provided with each operator for the most current information.

Determine the gauge of wire needed to safely accommodate the distance between the operator and the electrical box using either Table 2A for SINGLE PHASE or 2B for THREE PHASE (page 51).

NOTES:

1) The amount of electricity carried by a wire is restricted to the release of heat through the electrical insulation

material (the cable insulation can melt if the improper gauge is used).

2) Don’t run control wiring and power wiring in the same conduit, these wirings should be separated by 18”.
