SAFETY SUMMARY
It is imperative that everyone involved in the installation or operation of the gate operator read the
following warnings.
WARNING!
1. READ AND FOLLOW ALL INSTRUCTIONS. Improper installation of a gate operator
can result in a dangerous system. SAVE THESE INSTRUCTIONS.
2. A vehicle gate is a large, heavy object that is moved by an electric motor. A moving
gate can cause serious injury or death! The safety and well-being of others depends
on the installation of a safe system.
3. The entrance is for VEHICLES ONLY. Pedestrians must use a separate entrance.
Always keep people and objects away from the gate. NO ONE SHOULD CROSS THE
PATH OF THE MOVING GATE.
4. Choose one or more controls that together will allow complete control of the gate.
Most importantly, the gate must be able to be stopped at all times in case of
emergency, and the emergency control should be conveniently located, clearly
marked and visible.
5. All controls must be kept out of the reach of small children. Serious injury or death
can result from children playing with the controls.
6. All controls should be located so the person operating them can see the full area of
gate movement.
7. Use the emergency release only when the gate is not moving.
8. KEEP GATES PROPERLY MAINTAINED. Have a qualified person make repairs to the
gate hardware.
• Test the gate operator safety features monthly. The gate MUST reverse on contact
with a rigid object or stop when an object activates the non-contact sensors.
• After adjusting the force or the limit of travel, retest the gate operator. Failure to
adjust and retest the gate operator properly can increase the risk of damage, injury
or death.
9. Gate operators and associated control equipment should be installed by qualified
professional installers who should observe the following safe installation procedures:
• Power should always be disconnected whenever installing, wiring or servicing a
gate operator. Moving chains in gate operators can catch clothing or fingers and
cause severe injury.
• Installation of wiring should comply with local building and electrical codes.
• All manual gate locks should be disabled to avoid damage to the gate or gate
operator should the lock become engaged after the operator is installed.
• All operator controls and safety equipment should be tested at the conclusion of
installation to be sure they are functioning properly.
• The operation of the gate controls and safety equipment should be reviewed with
the owner and/or end user of the automated gate system. They should also be
informed of the need to maintain control and safety equipment on a regular basis.
Safety equipment should be checked monthly to ensure it is working properly. All
installation manuals and safety information should be left with the owner.
• Moving gates have pinch points and entrapment zones which can be extremely
dangerous to pedestrians, especially small children.

BASIC INSTALLATION HINTS AND RULES
PLEASE READ THIS SECTION VERY CAREFULLY BEFORE BEGINNING YOUR
INSTALLATION
1. UNDERSTAND THE SYSTEM AND INSTALLATION SITE THOROUGHLY. The SL 1000 is a
flexible and reliable gate operator system, but the quality of service depends directly on the
quality of installation. Please read these instructions carefully and study the applicable diagrams
before planning your installation. In particular, understand any site characteristics that may
affect the system installation.
WARNING
2. INSTALL PERMANENT WIRING. U.L. specifications require the model SL 1000 system to be
permanently wired. Refer to your local wiring code for specific information.
WARNING: Damage caused by faulty wiring is not covered by warranty.
3. U.L. OBSTRUCTION-SENSING REQUIREMENTS. To maximize safety, U.L. 325 standards
require primary obstruction sensing (gate sensitivity to impact) and secondary obstruction
sensing (photo-sensors) be in operation at all times.
4. GROUND THE SYSTEM. The system contains parts which may be damaged by static
discharge. A proper earth ground connected to the gate operator housing (at the lower left
grounding screw shown in Figure 15) will significantly reduce the chances of damage or
improper operation. The shielding in the cables specified for all remote sensors and controls
should also be connected to earth ground at the controller end of the cable only.
To be effective, the ground connection must be made by running 12 awg copper wire to a good
ground point (e.g., an electrical panel, a metallic cold water pipe that runs into the earth, or a
grounding rod at least 10 feet in length that is driven into the earth) within 12 feet of the system.
Even if you have a good earth ground, you should try to discharge any static before handling the
boards.
WARNING: Damage caused by static discharge or lightning is not covered by warranty.
5. PROVIDE POWER FROM A DEDICATED SOURCE. The outlet into which you connect the
Gate Operator should be wired to its own circuit breaker. This will reduce the line noise
introduced into system power and minimize the risk of having other equipment interrupt system
operation. In a Master/Slave system, master and slave must each have separate circuits.
6. DO NOT OVERLOAD THE TERMINAL BLOCKS. The terminal blocks are removable and the
pins are soldered into the boards. To connect your wires, remove the “head” from the correct
terminals and open the screws. Insert the wire into the correct opening on the front and tighten
the screw until the wire is held firmly. When you have made all connections for a given “head”,
plug it back onto the inputs designated for that terminal block.
Stranded wire must be between 16 and 24 awg. Solid wire must be between 18 and 24 awg.
This is the total thickness measurement so, if you are putting two wires in, the combined
thickness must fall within this range. NEVER try to insert more than two wire per terminal.
7. ENSURE GOOD CONNECTIONS. A light tug on the wire will tell you if the connection is secure.
When reconnecting system components, make sure all pins are straight on chips, connectors,
and terminal block heads.
8. READ MARKINGS CAREFULLY. The connection points are marked on the boards clearly.
Before making any connection, be sure to read the marking and check it against the
corresponding figure in these instructions so that you understand the connection you are making.
9. TRAIN YOUR CUSTOMERS THOROUGHLY. Although customer responsibility is limited to
proper installation, the quality of service is determined by care of system programming. Ensure
that the customer has a copy of this manual to guide them. It will save you and them lots of
inconvenience and aggravation later.

The concrete pad must be sufficient to support the gate operator and the forces
created by the moving gate. LiftMaster recommends a pad 20” wide by 30“ long by
24” deep (Figure 4).
The operator must be level and parallel to the gate, so the pad should be level and
about 4” above ground level to prevent water entrance.
Four anchor bolts are required to secure the gate operator to the pad. The mounting
holes in the gate operator are 5/8” in diameter. ½ ” x 3½” Red Head bolts are
recommended (Figure 5).
Be sure to provide access for wiring conduits (Figure 6).
Track installation should be on concrete, not asphalt, and should be at least 10” wide
and 6” deep.
A 6” gate overlap at the open end of the gate when closed should be provided.
A 30” gate overlap at closed end of the gate when closed should be provided.
NOTE: Shading indicates acceptable areas for conduit stub access.
Rev J
Doc 01-20098
Page 7 of 44
C. POWER WIRING
1. Provide a separate conduit stub for the AC power.
2. Each gate operator requires a 115 VAC 20 AMP single phase circuit
NOTE: Master and Slave units each require separate circuits to prevent false
overcurrent faults (see X3 Series Master/Slave Systems).
3. Wiring must comply with the local Electrical Code for operating a 1/2 HP motor. 12
AWG for up to 300' and 10 AWG for up to 500' long wire runs is suggested.
4. Be sure to pull a ground wire in the conduit for the connection to the gate operator.
NOTE: Do not rely on metallic conduit for earth ground.
D. LOOP DETECTORS AND PHOTO-SENSORS
1. A shelf is provided (10" x 11" x 18" high) to support non-LiftMaster loop detector
electronics. Power for the loop detector can come from the auxiliary 115 VAC plugs
in the gate operator or from the 24 VAC provided by the gate operator control board.
NOTE: The auxiliary plugs have power regardless of the unit power switch setting.
2. Conduit provisions should be made for the “loop” wire entrance to the loop detector.
3. Wiring should be 16-24 AWG stranded or 18-24 AWG solid.
NOTE: Optional LiftMaster-supplied loop detector add-on boards are available, both
pre-installed and for installation in the field. See Part 3, Gate Operator Options.
E. TELEPHONE CONNECTION
1. A conduit entrance into the gate operator should be provided for the telephone line.
2. A single twisted pair wire 18 AWG to 24 AWG, will be connected from the telephone
company termination block through the conduit to J9 on the control board. Polarity is not
important.
NOTE: Do not run telephone and AC power wires in the same conduit.
F. OTHER CONNECTIONS
1. Provisions should be made for conduit entrance into the gate operator for external
activation devices such as key switches, telephone entry systems, loops, etc.
2. Wire size requirement: 16-24 AWG stranded or 18-24 AWG solid wire should be used.
G. MASTER/SLAVE INTERCONNECTION (MASTER/SLAVE SYSTEM ONLY)
1. A conduit between the Master and Slave units should be provided for the Master/Slave
interconnection cable.
2. Two shielded twisted pair wire 16 AWG to 24 AWG will be connected between the two
units at TB1 on the controller board.
NOTES: 1. Do not run the Master/Slave cable and AC power wires in the same conduit.
2. Master/Slave interconnection cable should not exceed 3000' in length.
H. GROUNDING
1. The system contains parts which may be damaged by static discharge. A proper earth
ground connected to the gate operator housing will significantly reduce the chances of
damage or improper operation. The shielding in the cables specified for all remote
sensors and controls should also be connected to earth ground at the controller end of
the cable only.
2. To be effective, the ground connection must be made by running 12 AWG copper wire
to a good ground point (e.g., an electrical panel, a metallic cold water pipe that runs into
the earth, or a grounding rod at least 10' in length that is driven into the earth) within 12'
of the system. Even if you have a good earth ground, you should try to discharge any
static before handling the boards.

F. SETTING GATE OPEN DIRECTION SWITCHES S2 AND S3
Figure 12. Gate Direction and UPS Low Battery Switch Locations.
NOTE:
The Gate motion (left to right) is determined by looking at the gate from the
gate operator side.
• Switch S2 sets gate opening direction (open to left or open to right). Sensed only on
power up, it should be set when the power is off, or power should be cycled after
setting the switch.
1. Set switch S2 to RIGHT for gate to open to right, or to LEFT for gate to open to left.
2. Set switch S3 to the direction you wish the gate to move (left or right) and remain
when the LOW BATTERY input is activated by an Uninterruptable Power Supply
(UPS).
G. POWER UP PROCEDURE
CAUTION
If gate is positioned at the ‘open’ limit, gate will automatically
close if Relcose Timer is enabled and power is switched on.
Position gate either at the closed limit or at no limit when
preparing to switch power on. Always use extreme caution and
follow all warnings in the Safety Summary.
1. Turn on circuit breaker that provides power to gate operator.
2. Turn on gate operator power switch and verify that the seven-segment LED display
above the keypad sequentially spells out “HELLO”. The only LEDs that should
remain on are MAGLOCK and CLOSE LIMIT or OPEN LIMIT, if one of the limit
switches is engaged.
NOTE: If the LEDs do not follow this pattern, the controller board may not be working
correctly. Stop installation and call LiftMaster Technical Support for assistance.

J. GATE SENSITIVITY ADJUSTMENTS
The gate operator monitors both average and peak motor current. When the gate
encounters an obstruction, the gate operator senses the change in motor current and
reverses the gate. Three sensitivity adjustments must be set for each installation:
• Right gate motion (R69)
• Left gate motion (R160)
• Start-up current (R203)
♦ If your installation requires setting switch S2 to the “Open to Right” position, use the
“Open to Right" adjustment procedures below. If your installation requires setting S2
to the “Open to Left” position, use the “Open to Left" adjustments following the "Open
to Right" procedures.
♦ The minimum sensitivity is full clockwise and maximum sensitivity is full counter
clockwise. These adjustments must be made while the gate is in motion.
♦ Before starting the adjustments, verify that the Left and Right reverse pots are set
fully clockwise, and the Start-up pot is set to the 11 o’clock position (See Fig. 15).
♦ Make all adjustments in the order listed.
NOTE: Current flow varies with temperature. Do not tune the sensitivity
measurements too finely, or they may cause false overcurrent faults to occur
during cold weather.

IMPORTANT: Before proceeding, see NOTES below.
1. Wire all external control devices to their connections on the control board as shown. See
Appendix A for details on how each control input affects the gate operator.
2. Connect the Master/Slave interconnect cable (see Series X3 Master/Slave Systems, Part 1).
NOTES
1. Disconnecting the STOP terminal from the COMMON terminal stops the gate and prevents all
commands from having any effect. Manual Open does not activate the Reclose Timer.
IMPORTANT: As per UL325 standards, install the Manual Inputs and Fire switches in the line of
sight with the gate.
2. If gate(s) are used for bi-directional traffic, the Exit Loop should be a directional loop detector.
3. Inside and Outside Interrupt Loops:
♦ For maximum safety, Inside and Outside Interrupt loops require separate loop
detectors.
♦ Bipart of Bipart Latch: If only one loop detector is used, connect Outside loop to the
Inside loop detector.
4. Battery is used to store date and time.
M. POST INSTALLATION PROCEDURES
1. Setup
1. Turn on the main power at the gate operator's circuit breaker.
2. Verify that switch S2 (the Gate Open Direction switch) is set to the correct position.
3. Turn on the unit power switch .
2. Manual inputs
1. Verify that Manual Open fully opens the gate and that the open limit switch stops the gate.
2. Verify that Manual Close fully closes the gate and that the close limit switch stops the gate.
3. Verify that Manual Stop stops the gate.
Note: If the gate stops due to an Obstruction Fault, readjust the gate sensitivity pots.
3. Mechanical
Use the Manual Input commands to verify that:
1. The gate swings open and closed smoothly.
2. There is no squeak or vibration in the gate when it is moving .
3. There is no belt slippage when the gate moves or stops.
4. There is no slack in the closed gate due to loose chain or parts.
5. Bi-Parting gates only: Both gates open and close at the same time.
4. Gate Sensitivity and Obstruction Alarm (Primary Obstruction Sensing per UL 325)
1. Left/Right Obstruction sensitivity:
Apply a bump to the opening and closing gate and verify that the gate stops or reverses.
Rev J
Doc 01-20098
Page 20 of 44
2. Start-Up Sensitivity:
Apply a bump to the gate as it starts moving and verify that the gate responds to the bump within a
second.
3. Obstruction Alarm:
Cause two obstruction faults before the gate reaches its open or closed limit and verify that the
Obstruction Alarm sounds.
5. Entry inputs
1. Activate the CYCLE input (entry system), RADIO input (radio transmitter), and EXIT Loop input
(driving over the exit loop) and verify that they fully open the gate. If Reclose Timer is enabled, it will
close the gate.
2. Activate the FIRE input (fire department switch) and verify that the gate fully opens and then
closes after 5 seconds. If Reclose Timer is enabled, it will close the gate.
6. Alternate Action
If Alternate Action has been selected so that CYCLE or RADIO commands both open and close the
gate:
Activate the CYCLE command, wait until the gate is fully open, then activate the CYCLE command
again. The gate should close, verifying Alternate Action operation.
Note: If you select Alternate Action, you can't enable ATG and RT in procedures 7 and 8.
7. Reclose Timer (RT)
If Reclose Timer has been enabled in programming step 8, verify Reclose Timer as follows:
1. Activate any entry command (except Manual OPEN) to open the gate.
2. Start timing when the gate reaches fully open and verify that the Reclose Timer recloses the gate
after the desired interval.
NOTE: Reclose Timer is not functional when the Manual OPEN command is used.
8. Inside Interrupt Loop and Anti-Tailgating (ATG) When Exiting
GATE TYPE is SLIDE
ATG OFF:
If ATG is turned OFF (0 entered in step 6), activate the CYCLE command, drive over the Interrupt Loop
and verify its operation:
#
Opening Gates: When a vehicle drives on the Interrupt Loop an opening gate will be
unaffected.
#
Closing Gates: When a vehicle drives on the Interrupt Loop a closing gate will open and the
Reclose Timer (if enabled) will start.
ATG ON: If ATG is turned ON (1 entered in step 6), activate the CYCLE command, drive over the
Interrupt Loop and verify its operation:
#
Opening Gates: When a vehicle drives on the Interrupt Loop an opening gate will continue to
open, but will close as soon as the vehicle drives off the Interrupt Loop.
#
Closing Gates: When a vehicle drives on the Interrupt Loop a closing gate will stop, but will
close as soon as the vehicle drives off the Interrupt Loop.

B. FAULT LIST
The following conditions can cause a fault:
1. Instantaneous motor overcurrent (left/right obstruction sense) due to an
object physically obstructing the gate or gate track (UL325 requirement).
2. Average motor overcurrent (overload) caused by excessive motor current
(UL325 requirement).

sensor.
4. Inoperative motor caused by an open motor winding, broken or unconnnected
input motor wires, thermal overload, or unsupervised motor (UL325
requirement).
5. Limit switch staying closed when gate is supposed to move, caused by a
broken V-belt, defective limit switch, or defective limit cams.
6. Maximum motor run time exceeding 75 seconds.
A. If faults 1 through 3 occur only once during opening or closing, the gate reverses
a few inches and stops. Fault may be cleared by removing the obstruction and
cycling any command (Manual Inputs, FIRE, Cycle, Radio, EXIT).
B. If two sequential faults (a combination of faults 1 through 3 and Photo-Sensor
activation) occur during opening or closing, gate stops and Obstruction Alarm
sounds off for 5 minutes. Fault may be cleared by removing the obstruction and
cycling Manual Inputs or FIRE.
C. If fault 4 occurs, gate stops and Obstruction Alarm sounds off for 5 minutes. Fault
may be cleared by cycling Manual Inputs or FIRE.

D. MAINTENANCE
WARNING
To avoid injury, always turn off the unit power switch before working on gate.
Regular performance of preventive maintenance is essential for reliable system
operation because it corrects small problems before they turn into emergencies.
LiftMaster recommends performing preventive maintenance every 6 to 12 months,
depending upon the amount of gate usage.
•
If the gate is installed in a private residence or small apartment house where
usage is not severe, yearly preventive maintenance is acceptable.
•
If the gate is installed in a high-traffic application, semi-annual preventive
maintenance is essential.
1. PREVENTIVE MAINTENANCE TASKS
1.
Gate: must roll freely without any impediment. Check wheels, grease if necessary.
2.
Chain: Check for wear and tension. If loose, adjust chain tension. Do not oil chain.
3.
Sprocket: must not be loose on the shaft. Tighten set screws if loose !.
4.
Idlers: Check for wear. Tighten bolts if loose. Do not oil idler assembly.
5.
Limit switches: contacts must bounce back rapidly when they are pressed and
release. Cam lock plate (see Figure 15) must firmly hold the cams. Do not oil
gearbox shaft.
6.
Belt: Check for wear and tension (25 to 30 lbs.). Adjust the AC motor up or down to
set proper tension.
7.
Pulleys: must all line up and be firmly secured to their shafts. Tighten set screws if
loose !.
8.
Gear Box: Check for no oil leakage around the bushings. Do not oil gearbox.
9.
Control board: Check for water damage or burned spots. All connectors secured to
the board.
10. Wiring: Check all wiring for any insulation damage. Check for loose wire
connections.
11. No Rust: Check for rust throughout the unit. Check corners for water entrapment.
12. Fire Open: Activate Fire department switch to verify emergency gate opening.
13. Gate Sense: Check for the gate sensitivity (refer to Part 2, System Installation,
Section J, Gate Sensitivity Adjustments).
14. Photo-Sensors: Ensure that sensor emitters/receivers are aligned and clean. Verify
that inputs stop gate.
15. Obstruction Alarm: Check for proper operation. Alarm must sound after two
consecutive gate obstruction faults.
NOTES: !: To prevent loosening, LOCTITE threadlocker 242 is applied to set screws.

FUNCTIONAL INPUTS
NOTES: ! The term "activation" means closing an input circuit (via a relay or switch), and
may be momentary or continuous. Momentary activations are superceded by any
command. Continuous activations are superceded only by an overriding
command.
$ Activating any command when gate is at the open limit stops the Reclose
Timer. When the command (except Manual CLOSE and STOP) is cleared, the
Reclose Timer is reset.
MANUAL INPUTS: OPEN, CLOSE, AND STOP (TB2)
MAN OPEN
Activation fully opens the gate. Continuous activation holds
gate open. MAN OPEN overrides Anti-Tail-gate (ATG), Reclose
Timer, and all controls but MAN STOP.
MAN CLOSE
Activation fully closes the gate. Continuous activation holds
gate closed. MAN CLOSE overrides all controls but MAN STOP,
MAN OPEN and FIRE.
MAN STOP
De-activation stops opening and closing gates. MAN STOP
overrides Reclose Timer and all other controls, manual or
automatic. If MAN STOP is disconnected from its COMMON,
no commands affect the gate.
ENTRY SYSTEM/FIRE SWITCH INPUTS (TB9)
CYCLE
Reclose Timer OFF:
Alternate Action allows a single command to both open and close
the gate. Activation opens the gate, which remains open until
another command is received. A CYCLE command when the
gate is fully open closes the gate. CYCLE also opens a closing
gate. If Anti-Tailgating (ATG) is enabled, Alternate Action is
disabled. With ATG enabled, the gate begins closing as soon as
the INTERRUPT LOOP clears.
Reclose Timer ON:
Activation opens the gate, then the Reclose Timer closes the
gate. A CYCLE command also opens a closing gate, but will not
close a fully open gate if the Reclose Timer is enabled. If AntiTailgating (ATG) is enabled, the gate closes as soon as the
INTERRUPT LOOP clears.
FIRE
Activation opens the gate. Continuous activation holds the gate
open. If the Reclose Timer is disabled and FIRE is deactivated,
the gate closes after 5 seconds. If Reclose Timer is enabled, when
FIRE is deacitvated, the Reclose Timer starts. FIRE overrides all
commands but Manual STOP.
EXIT LOOP/SHADOW LOOP DETECTOR INPUTS (TB10)
EXIT LOOP
Same as CYCLE, but does not close the gate when it is fully open.
SHADOW LOOP Activation prevents the gate from opening or closing so the gate
won't hit a vehicle. If the gate is already moving, or if the gate is
not fully opened or closed, this input has no effect.

ADJUSTMENTS
OBSTRUCTION
Adjustable pot controls gate sensitivity to blockages by the
RIGHT (R69) instantaneous rise in motor current. When the limit is exceeded, the
gate reverses a programmed distance (minimum 2 inches).
OBSTRUCTION
Adjustable pot controls gate sensitivity to blockages by the
LEFT (R160) instantaneous rise in motor current. When the limit is exceeded, the
gate reverses a programmed distance (minimum 2 inches).
NOTE: LiftMaster gate operators have two obstruction sense adjustments (left and right)
where other gate operators have only one. This allows greater flexibility
of installation. For instance, you can install a gate on an incline and not
worry about sacrificing downhill gate sensitivity.
START-UP
(R203)
Adjustable pot controls the delay in sensitivity to gate
obstructions. This delay in sensitivity prevents the initial motor
inrush current from causing a obstruction fault. The weight of the
determines this setting.
