Safety Installation Information

1. Vehicular gate systems provide convenience and security. 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 edge sensors (contact), guards for exposed rollers, photoelectric sensors, screen mesh, vertical posts, and 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 the owner's manual regarding placement of non-contact sensors for each type of application (see Install Entrapment Protection); (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 is not obstructed or impeded by building structures, natural landscaping or similar obstruction. A wireless device shall function under the intended end-use conditions.

Gate Construction Requirements (ASTM F2200)

LiftMaster states that vehicular gates should be installed in accordance with ASTM F2200, Standard Specification for Automated Vehicular Gate Construction. The manual lists these provisions:

General requirements

• Gates shall be constructed in accordance with the provisions given for the appropriate gate type.
• Gates shall be designed, constructed and installed to not fall over more than 45 degrees from the vertical plane when a gate is detached from the supporting hardware.
• Gates shall have smooth bottom edges, with vertical bottom edged protrusions not exceeding 0.50 inches (12.7 mm) other than the exceptions listed in ASTM F2200.
• The minimum height for barbed tape shall not be less than 8 feet (2.44 m) above grade and for barbed wire shall not be less than 6 feet (1.83 m) above grade.
• An existing gate latch shall be disabled when a manually operated gate is retrofitted with a powered gate operator. A gate latch shall not be installed on an automatically operated gate.
• Protrusions shall not be permitted on any gate (see ASTM F2200 for exceptions).
• Gates shall be designed, constructed and installed such that their movement shall not be initiated by gravity when an automatic operator is disconnected. A vehicular horizontal slide gate shall not result in continuous, unimpeded movement in either lineal direction of its travel.
• For pedestrian access in the vicinity of an automated vehicular gate, a separate pedestrian access shall be provided or available, located so that a pedestrian does not come in contact with a moving vehicular access gate during the entire path of travel. A pedestrian gate shall not be incorporated into an automated vehicular gate panel.

Vehicular horizontal slide gates, Class I, II and III

• All weight bearing exposed rollers 8 feet (2.44 m) or less above grade shall be guarded or covered.
• All openings shall be designed, guarded, or screened from the bottom of the gate to the top of the gate or a minimum of 6 ft. (1.83 m) above grade, whichever is less, to prevent a 2-1/4 in. (57 mm) 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. The gate panel includes the entire section of the moving gate, including any back frame or counterbalance portion.
• A gap, measured in the horizontal plane parallel to the roadway, between a fixed stationary object nearest the roadway (such as a gate support post) and the gate frame when the gate is in either the fully open position or the fully closed position, shall not exceed 2-1/4 inches (57 mm). Exception: all other fixed stationary objects greater than 16 in. (406 mm) from the gate frame are not required to comply.
• Positive stops shall be required to limit travel to the designed fully open and fully closed positions, installed at either the top of the gate or the bottom of the gate, projecting horizontally or vertically no more than required to perform their intended function.
• All gates shall be designed with sufficient lateral stability to assure that the gate will enter a receiver guide.

Vehicular horizontal slide gates, Class IV

• All weight bearing exposed rollers 8 feet (2.44 m) or less above grade shall be guarded or covered.
• Positive stops shall be required to limit travel to the designed fully open and fully closed positions.

Specific applications: any non-automated gate to be automated shall be upgraded to conform to ASTM F2200; the specification does not apply to gates generally used for pedestrian access or to vehicular gates not to be automated; when the gate operator or the gate of an automated system is replaced, the existing or new gate shall conform to ASTM F2200.

LiftMaster SL3000UL Installation

LiftMaster presents SL3000UL installation as eight steps, followed by handing and limit adjustment and an obstruction test. Each step below is labeled with the matching LiftMaster step number.

1. Step 1, Determine location for operator
2. Step 2, Install the operator
3. Step 3, Attach the chain
4. Step 4, Install entrapment protection
5. Step 5, Earth ground rod
6. Step 6, Power wiring
7. Step 7, Dual gate setup
8. Step 8, Install the cover

After Step 8, continue with handing and limit adjustment and the obstruction test. Per LiftMaster, the handing and limits are set before the cover is installed.

Installation Requirements

LiftMaster describes two layouts (page 9):

• Standard installation: the operator is installed near the front roller of the gate.
• Rear installation: the operator is installed near the back of the gate in the OPEN position. This layout requires two extra idler pulleys.

Source: LiftMaster manual, 01-39375 revision B, page 9.

Site Preparation

• Check the national and local building codes BEFORE installation.
• Conduit and concrete pad: trench and install conduit. 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.
• 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.
• Gate: the gate must be constructed and installed according to ASTM F2200 standards (see Gate Construction Requirements), and must fit the specifications of the operator (see Specifications).
• Additional accessories: vehicle loops allow the gate to stay open when vehicles are obstructing the gate path. They are suggested for vehicles 14 feet (4.27 m) or longer and are not required but are recommended. Before installing your access control device(s), complete a site survey and determine the best device for your site needs.

Installing the Drive Chain (Step 3)

Source: LiftMaster manual, 01-39375 revision B, page 12.

To tighten the chain after it has stretched, see Drive Chain maintenance.

Installing Entrapment Protection Devices (Step 4)

Entrapment protection MUST be installed according to the UL 325 requirements. LiftMaster's 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 inches (406 mm) in a location up to 6 ft. (1.8 m) above grade.

Slide gate operators require a minimum of two external monitored entrapment protection devices to function; one in the open direction and one in the close direction. Every installation is unique. It is the responsibility of the installer to ensure that ALL entrapment zones are protected with an external monitored entrapment protection device, protecting both the open and close gate cycles. LiftMaster monitored external entrapment protection devices MUST be used with LiftMaster operators to meet UL 325 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.

LiftMaster's illustration (credited to the DASMA Gate Systems Safety Guide) shows an example site. See the original manual (page 13).

Wiring entrapment protection devices

LiftMaster describes three options for wiring external devices, depending on the device and how it will function. Refer to the manual included with your entrapment protection device. The 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 devices may be wired to the expansion board.

Earth Ground Rod (Step 5)

Use the proper earth ground rod for your local area. The ground wire must be a single, whole piece of wire. Never splice two wires for the ground wire. If you cut the ground wire too short, break it, or destroy its integrity, replace it with a single wire length.

1. Install the earth ground rod within 3 feet (.9 m) of the operator.
2. Run wire from the earth ground rod to the operator.

LiftMaster notes that if the operator is not grounded properly the range of the remote controls will be reduced and the operator will be more susceptible to lightning and surge damage.

Source: LiftMaster manual, 01-39375 revision B, page 15.

Power Wiring (Step 6)

For dual gate applications, power will have to be connected to each operator. An optional Transformer Kit (Model 3PHCONV) can be used to change the input voltage (208/240/480/575 Vac) to an output voltage of 120 Vac (see Accessories). If using an external receiver, use shielded wire for the connections and mount the receiver away from the operator to avoid interference from the operator.

Wiring Accessories to the SL3000UL Control Board

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. LiftMaster describes these control board inputs and outputs (pages 25 and 26):

SL3000UL control board inputs and outputs

Swipe sideways to see all columns.

At least two external monitored entrapment protection devices are required prior to gate movement, one in the open and one in the close direction. Only ONE monitored device may be connected to each input. 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 indicating it is working properly, it will not run in that direction.

Source: LiftMaster manual, 01-39375 revision B, pages 25 to 26.

Expansion Board and Accessory Connections

Expansion board switches

• EXIT FAIL switch. OPEN: if the EXIT plug-in loop detector (model LOOPDETLM) detects a fault, then the gate will open and remain open until the fault is cleared. CLOSE: if the EXIT plug-in loop detector detects a fault, faults are ignored (EXIT loop is faulted and inoperative).
• AC FAIL switch. NOT USED.
• ANTI TAIL switch. OFF: when the CLOSE EYES/Interrupt loop is activated it causes a closing gate to stop and reverse. ON: when the CLOSE EYES/Interrupt loop is activated it causes a closing gate to pause; once the vehicle is clear the gate will continue to close.
• QUICK CLOSE switch. OFF: no change to the gate's normal operation. ON: when the CLOSE EYES/Interrupt loop is deactivated it causes an opening or a stopped gate to close (ignores the Timer-to-Close).

Source: LiftMaster manual, 01-39375 revision B, page 27.

Auxiliary relays 1 and 2

The auxiliary relays provide Normally Open (N.O.) and Normally Closed (N.C.) relay contacts to control external devices, for connection of Class 2, low voltage (42 Vdc [34 Vac] max 5 Amps) power sources only. The function of the relay contact activation is determined by the switch settings.

Cycle count (LiftMaster): first, note the current Aux Relay switch positions. 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 the 1 LED blinking 1000's, the 2 LED blinking 10,000's, the 3 LED blinking 100,000's, and all three LEDs blinking together for 1,000,000's (example: the 1 LED blinks 3 times, the 2 LED blinks 6 times, and the 3 LED blinks once; the cycle count is 163,000). The cycle count displayed is between 1,000 and 9,999,000 cycles. After servicing, set the Aux Relay switches back to their appropriate positions. The 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. The expansion board will flash the cycle count 3 times, then all the LEDs will turn on solid for 10 seconds, then turn off.

The manual also contains a red/green light functionality table (red light wired to Aux Relay 1, green light to Aux Relay 2) on page 28.

LiftMaster SL3000UL Adjustment

Adjust the Handing and Limits

The adjustments allow you to set where the gate will stop in the open and close position. The force is adjusted automatically when you set the limits but should be fine tuned using the FORCE dial on the control board. The test buttons on the control board will not work until the handing is set. 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.

OPEN RIGHT: if the operator is installed on the right side of the driveway when looking out of the property, the gate should be set to open right. OPEN LEFT: if the operator is mounted on the left side of the driveway when looking out of the property, the gate should be set to open left.

LiftMaster SL3000UL Programming

How to Program a Remote Control

A total of 50 Security+ 2.0 remote controls or KPW250 keypads and 2 keyless entries (1 PIN for each keyless entry) can be programmed to the operator. When programming a third keyless entry to the operator, the first keyless entry will be erased to allow the third keyless entry to be programmed. When the operator's memory is full it will exit the programming mode and the remote control will not be programmed; the memory will need to be erased before programming any additional remote controls. If installing an 86LM to extend the range of the remote controls DO NOT straighten the antenna.

There are 3 different options for programming the remote control, depending on how you would like the remote control to function:

Source: LiftMaster manual, 01-39375 revision B, page 32.

How to Connect the SL3000UL to the LiftMaster Internet Gateway

The LiftMaster Internet Gateway is not provided. LiftMaster describes two ways to program the operator to the gateway.

Source: LiftMaster manual, 01-39375 revision B, page 33.

Constant Pressure Override, Gate Hold Open, and Erase Procedures

Constant Pressure Override (CPO)

Constant Pressure Override is for use with KPW5 and KPW250 keypads (not provided). The KPW5/KPW250 wireless commercial keypads are security keypads and can only be programmed to ONE gate operator (see the KPW5/KPW250 manual for complete programming instructions). The feature is intended to temporarily override a fault in the entrapment protection system, in order to operate the gate until the external entrapment protection device is realigned or repaired. Use the feature only in line of sight of the gate when no obstructions to travel are present. External entrapment protection devices include LiftMaster monitored photoelectric sensors and LiftMaster monitored wired and wireless edge sensors. Be sure to repair or replace these devices promptly if they are not working properly.

1. Enter a valid 4-digit PIN.
2. Press and hold # for 5 seconds to enter CPO. Continue to hold # to keep the operator in motion. A continuous tone will sound until the limit is met and/or # is released.
3. The operator will stop when either the operator reaches a limit or the user releases #.

Gate hold open feature

The gate hold open feature will disable the timer and keep the gate at the open limit. It can be activated with the reset button (see Reset Button) or through the KPW5 and KPW250 keypads (not provided). On a keypad: (1) enter a valid 4-digit PIN when the gate is at the open limit and the timer is running; (2) the operator will chirp, indicating the timer is canceled. To restart the gate: re-enter the 4-digit PIN, or activate a hard input or a programmed remote.

Erase all codes

1. Press and release the LEARN button (operator will beep and green XMITTER LED will light).
2. Press and hold the LEARN button again until the green XMITTER LED flashes and then release the button (approximately 6 seconds). All remote control codes are now erased.

Remove and erase monitored entrapment protection devices

1. Remove the entrapment protection device wires from the terminal block.
2. Press and release the OPEN LEFT and OPEN RIGHT buttons simultaneously. The handing direction LED will remain solid. The other direction LED will begin flashing (entering setup mode).
3. Press the OPEN LEFT and OPEN RIGHT buttons simultaneously to exit.

Gate Operator Setup Examples and Dual Gate Settings

LiftMaster provides example setups for the gate operator; your specific site requirements may be different. Always set up the operator system to the site requirements, including all necessary entrapment protection devices.

• Residential: one to four residential homes sharing a gated entrance/exit, allowing vehicle access trumps security concerns.
• Commercial/general access: a residential community (more than four homes) having one or more gated entrances/exits, allowing vehicle access trumps security concerns.
• Commercial: business site where security (gate closed) is important.
• Industrial: large business site where security is required.

LiftMaster SL3000UL Operation

SL3000UL Operator Overview

LiftMaster's operator overview (page 21) identifies these parts of the SL3000UL: antenna, limit switches (page 19), control board (pages 22 to 26), expansion board (pages 27 to 30), accessory power outlet, AC power switch, junction box (page 31), dust guard, cover, manual release handle, and reset button. The manual's illustration also shows the 1 HP operator.

• AC power switch: the AC power switch on the operator will turn the incoming 120 Vac power ON or OFF.
• Manual release handle: pull the manual release handle to manually open and close the gate. Use the manual disconnect release ONLY when the gate is not moving.

Source: LiftMaster manual, 01-39375 revision B, page 21.

SL3000UL Reset Button

The reset button has the following functions (LiftMaster, page 21):

• Press the reset button to stop a moving gate during a normal open/close cycle, like a stop button.
• Press the reset button once while the gate is in the open position to disable the Timer-to-Close. The gate will stay in the open position. To restart the Timer-to-Close, either press the reset button or activate the gate with a programmed remote control.
• Press the reset button to shut off the alarm and reset the operator.

Source: LiftMaster manual, 01-39375 revision B, page 21.

SL3000UL Control Board Overview

• LEARN button: used for programming (see Programming).
• Diagnostic display: shows the operator type, firmware version, and codes. The operator type displays as "SL" followed by a "30", which indicates the operator type as SL3000UL. The firmware version shows after the operator type (example "1.2"). See Diagnostic Codes.
• Handing buttons: used to determine which direction the gate will open, and to set the limits (see Adjustment). OPEN RIGHT: if the operator is installed on the right side of the drive when looking out of the property, a slide gate will slide to the right when opening. OPEN LEFT: if the operator is mounted on the left side of the drive when looking out of the property, a slide gate will slide to the left when opening. For gates installed on the outside of the property, the setting will be opposite; determine the direction by looking towards the property from the outside.
• Bipart delay: used in dual gate applications where a maglock, solenoid lock, or decorative overlay would require one gate to close before the other. It is also used in applications where one gate travels a longer distance than the other. The operator with the BIPART DELAY dial ON will delay from the close limit when opening and be the first to close from the open limit. BOTH OFF: no effect. BOTH ON: no effect.
• Timer-to-Close (TTC): factory set to OFF (0). Rotate the TIMER-TO-CLOSE dial to the desired setting (0 to 180 seconds). Any radio command, single button control, or CLOSE command on the control board before the TTC expires will close the gate. The TTC is reset by any signals from the open controls, loops, close edges, and close photoelectric sensors. 0 seconds (OFF): the gate will remain open until the operator receives another command from a control. 1 to 180 seconds (ON): the gate will automatically close after the specified time period.
• Reversal force dial: adjusts the force (see fine tune the force). Settings 1 to 3: fixed force settings. Settings 4 to 10: automatically increase the force due to gate wear or temperature changes.
• Test buttons: used to operate the gate (OPEN, STOP and CLOSE). Also used to view the code history (see How to Read Diagnostic Codes).
• Status LEDs: see the Control Board LEDs.

Gate Will Not Open or the LiftMaster SL3000UL Does Not Move

If a LiftMaster SL3000UL gate will not open or the operator does not move, LiftMaster's troubleshooting chart separates several conditions. Find the one that matches what you see.

The control board powers up, but the motor does not run

LiftMaster lists these possible causes and checks (chart row):

• Reset switch is stuck: Check reset switch.
• Stop button active or jumper not in place for stop circuit: Check Stop button is not "stuck on", or verify that the stop button is a normally closed circuit, or put a jumper on the stop circuit.
• Open or Close input active: Check all Open and Close inputs for a "stuck on" input.
• Entrapment Protection Device active: Check all Entrapment Protection Device inputs for a "stuck on" sensor.
• Vehicle loop detector or probe active: Check all vehicle detector inputs for a "stuck on" detector.
• Defective control board: Replace defective control board.

The gate closes but will not open

LiftMaster lists this possible cause and check (chart row):

• Vehicle loop detector active: Check all vehicle detector inputs for an active detector.

The operator does not respond to a command

For wired controls such as Open, Close, or SBC, see the chart row. For remotes and transmitters, see remote control problems.

The gate moves but limits cannot be set correctly

See the chart row for "cannot set correct limits" and the chart row for "does not fully open or fully close when setting limits." See Adjust the Handing and Limits.

The gate stops during travel and reverses immediately

LiftMaster lists these possible causes and checks (chart row):

• Control (Open, Close) becoming active: Check all Open and Close inputs for an active input.
• Vehicle loop detector active: Check all vehicle detector inputs for an active detector.

Source: LiftMaster manual, 01-39375 revision B, page 41.

Gate Opens but Will Not Close on the LiftMaster SL3000UL

When a LiftMaster SL3000UL gate opens but will not close with a transmitter or the Timer-to-Close, LiftMaster lists the following possible causes and checks (chart row):

• Open control active: Check all Open inputs for an active input.
• Vehicle loop detector active: Check all vehicle detector inputs for an active detector.
• Fire Dept input active: Check Fire Dept input.
• Timer-to-Close not set: Check Timer-to-Close (TTC) setting.
• Close Entrapment Protection Device active: Check all Entrapment Protection Device inputs for an active sensor.

If the display shows a code, see code 60 and codes 61 to 66 and 70 to 75 for entrapment protection inputs. LiftMaster's chart also has rows for an exit loop that does not open the gate, an interrupt loop that does not stop and reverse the gate, and a shadow loop that does not keep the gate at the open limit.

LiftMaster SL3000UL Has No Power or the Display Is Off

If the LiftMaster SL3000UL does not run and the diagnostic display is not on, LiftMaster lists these possible causes and checks (chart row):

1. No power to control board: Check AC power.
2. Open fuse: Check fuses.
3. Defective control board: Replace defective control board.

The AC power switch on the operator turns the incoming 120 Vac power ON or OFF. Related codes in LiftMaster's table include code 53, brownout occurred.

LiftMaster SL3000UL Remote Control Does Not Operate the Gate

For a wireless control or transmitter that does not operate a LiftMaster SL3000UL gate, LiftMaster lists these causes and checks (chart row):

1. Check XMITTER LED when wireless control is active: Activate wireless control and check XMITTER LED is on. Re-learn wireless control/transmitter to control board. Replace wireless control as needed.
2. Stop button is active: Check Stop button is not "stuck on".
3. Reset button is stuck: Check Reset button.
4. Poor radio reception: Check if similar wired control operates correctly. Check if wireless controls works properly when within a few feet of operator. Check operator's antenna and antenna wire. Check other wireless controls or devices.

To re-learn a remote, see How to Program a Remote Control. If the operator's memory is full, LiftMaster notes that the memory must be erased before more remote controls can be programmed (Erase All Codes).

LiftMaster SL3000UL Safety Device Problems

The LiftMaster SL3000UL will not run unless a minimum of two external entrapment protection devices are connected, one in the open direction and one in the closed direction. LiftMaster's chart covers these safety device symptoms:

• Photoelectric sensor does not stop or reverse the gate (row): Incorrect photoelectric sensor wiring: Check photoelectric sensor wiring. Retest that obstructing photoelectric sensor causes moving gate to stop, and may reverse direction. Defective photoelectric sensor: Replace defective photoelectric sensor. Retest that obstructing photoelectric sensor causes moving gate to stop, and may reverse direction. Photoelectric sensors installed too far apart: Move the photoelectric sensors closer together or use edge sensors instead.
• Edge sensor does not stop or reverse the gate (row): Incorrect edge sensor wiring: Check edge sensor wiring. Retest that activating edge sensor causes moving gate to stop and reverse direction. Defective edge sensor: Replace defective edge sensor. Retest that activating edge sensor causes moving gate to stop and reverse direction.
• Obstruction does not cause the gate to stop and reverse (row): Force adjustment needed: Refer to the Adjustment section to conduct the obstruction test and perform the proper force adjustment that is needed.
• Alarm sounds for 5 minutes or with a command (row): Double entrapment occurred (two obstructions within a single activation): Check for cause of entrapment (obstruction) detection and correct. Press the reset button to shut off alarm and reset the operator.
• Expansion board function not controlling the gate (row): Defective main board to expansionboard wiring: Check main board to expansion board wiring. If required, replace wire cable. Incorrect input wiring to expansion board: Check wiring to all inputs on expansion board. Defective expansion board or defective main board: Replace defective expansion board or defective main board.

Swipe sideways to see all columns.

LiftMaster's notes:

• Severe or high cycle usage will require more frequent maintenance checks.
• Limits may have to be reset 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.

Drive Chain

Over time, the drive chain on the operator will stretch and need to be tightened. To tighten the drive chain, adjust either of the two chain eye bolts. The chain should have no more than 1 inch of sag for every 10 feet of chain length.

Frequently Asked Questions About the LiftMaster SL3000UL

What size gate can each SL3000UL model move?

Per the manual (page 7), the SL3000501UL (1/2 HP) is rated for gates up to 1,000 lbs. (453.6 kg) and the SL3000101UL (1 HP) for gates up to 2,000 lbs. (907.2 kg). Both models handle a minimum travel of 4 feet (1.2 m) and a maximum of 52 feet (15.85 m) at up to 1 foot per second. See Specifications.

How do I set the handing and limits?

LiftMaster's steps are on pages 19 and 20 of the manual: set the handing with the OPEN LEFT and OPEN RIGHT buttons, set the OPEN and CLOSE limits by adjusting the limit nuts or cams, then set the force and run distance by running one full cycle. Perform the obstruction test afterward. See Adjust the Handing and Limits.

How do I open the gate by hand?

The manual's operator overview (page 21) shows a manual release handle: pull it to manually open and close the gate. Use the manual disconnect only when the gate is not moving. See Operator Overview.

What does the reset button do?

It stops a moving gate during a normal cycle, disables the Timer-to-Close when pressed once at the open position, and shuts off the alarm and resets the operator (page 21). See Reset Button.

How many entrapment protection devices does the SL3000UL need?

The operator will not run unless a minimum of two external monitored entrapment protection devices are connected, one in the open direction and one in the close direction, and every entrapment zone must be protected (pages 13 and 26). The carton includes a monitored retro-reflective photoelectric sensor (LMRRUL) and a 5 ft. edge sensor kit (S505AL). See Installing Entrapment Protection Devices.

What wire gauge and length can I use?

See the maximum wire length table for the 1/2 HP and 1 HP operators and the 3PHCONV transformer kit in Power Wiring (page 15). Use copper conductors only.

What warranty does the SL3000UL have?

Per the manual, LiftMaster's warranty is a 7 year residential / 5 year commercial limited warranty. The warranty terms, including exclusions, are printed on page 46 of the manual, and warranty service starts with a call to 1-800-528-2806 before dismantling or returning the product.
