SAFETY SUMMARY
It is imperative that everyone involved in the installation or operation of the LiftMaster model SL 1000-
X1 Slide Gate Operator reads the following warnings.
WARNING!
•
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.
•
•
Improper installation of a gate operator can result in a dangerous system.
Gate operators can present serious hazards to persons in the immediate area when
not controlled in a safe manner. 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.
•
•
•
All controls must be kept out of the reach of small children. Serious injury or death
can result from children playing with the controls.
All controls should be located so the person operating them can see the full area of
gate movement.
Gate operators and associated control equipment should be installed by qualified
professional installers who should observe the following safe installation procedures:
1. 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.
2. Installation of wiring should comply with local building and electrical codes.
3. 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.
4. All operator controls and safety equipment should be tested at the conclusion of
installation to be sure they are functioning properly.
5. 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.
6. 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.
In the sections that follow, detailed procedures are discussed for each step required to install a model
SL 1000-X1 system. In addition to these specific procedures, there are a number of general hints and
rules which will help ensure that your installation will be done correctly and efficiently. These are
discussed below.
1. UNDERSTAND THE SYSTEM AND INSTALLATION SITE THOROUGHLY. The SL 1000-X1 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-X1 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. 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 16) 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.
4. 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.
5. DO NOT OVERLOAD THE TERMINAL BLOCKS. The terminal blocks used in the gate operator 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 pins 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 wires per terminal.
6. 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.
7. READ THE 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.
8. 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 the manual, Programming Instructions for LiftMaster SL 1000-X1 and SW
2000-X1 Gate Operators (Doc. No. 6001193) to guide them. It will save you and them lots of
inconvenience and aggravation later.

2. The gate operator requires a 115 VAC 20 AMP single phase circuit.
3. Be sure to pull a ground wire in the conduit for the connection to the gate operator.
Important: Do not rely on metallic conduit for earth ground.
D. LOOP DETECTORS
•
The gate operator has a shelf that can support 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.
•
•
Conduit provisions should be made for the “loop” wire entrance to the loop detector.
The shelf space provided is approximately 4” x 10” x 18” high.
NOTE: Shelf space on systems without the Power Fail Option is about 10" x 10" x18".
E. TELEPHONE CONNECTION
•
•
Provisions should be made for a conduit entrance into the gate operator for the telephone line.
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
Provisions should be made for conduit entrance into the gate operator for external activating
devices such as key switches, telephone entry systems, etc.

J. POWER FAIL OPERATION OPTION CONNECTION
a) Power Fail Operation Option Connection
CAUTION
Perform the next step (battery hookup) with care. Interchanging battery wires temporarily opens
the the resettabale fuse on gate operator board, disabling the power fail option.
To ensure a safe installation, the gate operator is shipped with the battery partially disconnected
from the Power Fail Option electronics. To enable this option:
•
Connect white/red wire of option harness to positive (+) battery terminal.
b) Power Fail Operation Option Test
NOTES:
The following procedures require turning main power to the gate operator off and on at its
dedicated circuit breaker. DO NOT shut off the Gate Operator Power switch unless
specifically directed by the procedure, since this will shut off everything, including the
Power Fail Operation option.
•
•
Because the battery may not be fully charged at the time of the test, we strongly suggest
moving the gate only one foot when performing the power fail test.
1. Set Power Fail switch S2 to the same position as switch S1 (Figure 12).
2. Turn on gate operator power switch.
3. Using the manual controls (Figure 13), initiate gate opening, then stop the gate about one
foot short of its fully open position.
4. Turn off main power to the gate operator. After about one minute the gate should start
opening and stop at its fully open limit.
5. Turn on main power to the gate operator.
6. Set Power Fail switch S2 to the opposite position.
7. Using the manual controls, initiate gate closing, then stop the gate about one foot short of its
fully closed position.
8. Turn off main power to the gate operator. After about one minute the gate should start
closing and stop at its fully closed limit.
9. Turn on main power to the gate operator.
10. Set Power Fail switch S2 to the direction you desire the gate to move after a power outage.

MODEL SL 1000-X1 OPTIONS
POWER FAIL OPERATION OPTION
The LiftMaster Power Fail Operation Option may be ordered pre-installed in new units, or can be
purchased separately for installation in LiftMaster gate operator systems in the field. The Power Fail kit
includes a DC motor, belt, battery, battery support bracket assembly (includes bracket, 3 control relays,
rectifier and wire harness) and mounting hardware. Features of the Power Fail Option are as follows:
•
The Power Fail Operation system fully opens or closes the the gate (User's choice) one minute after
a power outage. The gate will remain open or closed until AC power is restored.
•
When AC power is restored, the battery is charged up to its full potenial, then continuously trickle
charged. Recharging takes from one to five hours, depending on the weight of the gate and how far
it moved during the outage. The age of the battery also increases the battery charging time.
NOTE: Battery capacity decreases over time. Battery should be replaced every two or three years.
•
•
The charging section and controls for the Power Fail Operation are located on the control board.
The motor sensing potentiometers (Right reverse, Left reverse and Inrush) on the Gate Operator
board may require readjustment if the Power Fail Operation option is installed in the field.
•
Gate speed may be slightly reduced with the Power Fail Operation option installed.
IMPORTANT NOTE
During a power outage, all Gate Operator safety features are
disabled and only the limit switches stop movement of the gate.

D. MAINTENANCE
WARNING
To avoid injury, always turn off the unit power switch before working on gate.
Regularly 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.
PREVENTIVE MAINTENANCE TASKS

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
MAN STOP
Activation fully closes the gate. Continuous activation holds gate closed.
MAN CLOSE overrides all controls but MAN STOP, MAN OPEN and FIRE.
Activation stops opening and closing gates. MAN STOP overrides Reclose
Timer and all other controls, manual or automatic. If MAN STOP is
connected to its COMMON, no commands affect the gate.
ENTRY SYSTEM/FIRE SWITCH INPUTS (TB9)
OPEN Reclose Timer disabled:
Activation opens the gate, which remains open until another command is
received. An OPEN command when the gate is fully open closes the gate.
This Alternate action allows a single command to both open and close the
gate. OPEN also opens a closing gate. If Anti-Tailgating (ATG) is ON,
Alternate Action is disabled. With ATG enabled, the gate begins closing as
soon as the SAFETY LOOP clears.
Reclose Timer enabled:
Activation opens the gate, then the Reclose Timer closes the gate. An
OPEN command also opens a closing gate, but will not close a fully open
gate if the Reclose Timer is enabled. If Anti-Tailgating (ATG) is enabled, the
gate closes as soon as the SAFETY LOOP clears.
FIRE
Activation opens the gate. Continuous activation holds the gate open. If
Reclose Timer is disabled, when FIRE is deactivated, gate closes
immediately. If Reclose Timer is enabled, when FIRE is deacitvated, the
Reclose Timer starts. FIRE overrides all commands but Manual STOP.
EXIT LOOP DETECTOR INPUTS (TB10)
EXIT LOOP
Same as OPEN, but does not close the gate when it is fully open.
SHADOW LOOP (Swing gates only) 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.
SAFETY LOOP DETECTOR/SAFETY BAR INPUTS (TB11)
SAFETY LOOP SWING with ATG enabled
Activation prevents the gate from opening or closing and halts a closing gate.
When Safety Loop clears, the gate continues closing. If gate is opening or is
fully open, when the Safety loop clears, the gate begins closing.
SWING with ATG disabled
Activation prevents the gate from opening or closing and stops a moving
gate. When Safety Loop clears, the gate resumes its course.
SLIDE with ATG enabled
Activation prevents the gate from closing and halts a closing gate. When the
Safety Loop clears, the gate continues closing. If the gate is opening or is
fully open, when the Safety Loop clears, the gate begins closing.
SLIDE with ATG disabled
Activation prevents the gate from closing and opens a closing gate. Gate
fully opens and starts the Reclose Timer if timer is enabled.

SAFETY BAR
Activation causes the gate to reverse for a programmable distance and stop. If
Max Retry Count is enabled, gate waits a programmable pause time, then retries.
The gate will retry up to twice before faulting out.
RADIO INPUT (TB6)
RADIO RECV
Convenience terminals provide power and contact connection for a radio
receiver. Activation is the same as OPEN.
WARNING (TB8)
WARNING OUT Relay contacts close depending on the programmed setting of the warning
relay.
MAG LOCK INPUT (TB4)
MAG LOCK
Relay contacts close when the gate is fully closed.
SLAVE I/O INPUT (TB1)
SLAVE I/O
Input/output terminals are used to control a second gate operator.
PHONE LINE (J9)
PHONE LINE
Terminals connect the telephone line to the gate operator.
ADJUSTMENTS
OVERLOAD
(R72)
Factory-set pot protects the gate operator from excessive motor current.
If MAX Retry is enabled, when the limit is exceeded, a closing gate reverses
a programmed distance and an opening gate stops, waits a programmed
pause time, then tries to resume. The gate will retry up to twice before
faulting out.
NOTE: Gate may be more sensitive to drag in one direction than the other.
NOTE: For swing gate operation, controls are Right/Clockwise and Left/Counterclockwise.
REVERSE
SENSE
RIGHT (R69)
Adjustable pot controls gate sensitivity to blockages by the instantaneous
rise in motor current. If MaxRetry count is enabled, when the limit is
exceeded, a closing gate reverses a programmed distance and an opening
gate stops, waits a programmed pause time, then tries to resume. The gate
will retry up to twice before faulting out.
REVERSE
SENSE
LEFT (R160)
Adjustable pot controls gate sensitivity to blockages by the instantaneous
rise in motor current. If MaxRetry count is enabled, when the limit is
exceeded, a closing gate reverses a programmed distance and an opening
gate stops, waits a programmed pause time, then tries to resume. The gate
will retry up to twice before faulting out.
NOTE: LiftMaster gate operators have two reverse sense adjustments
(right/clockwise and left/counterclockwise) 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.
INRUSH
(R203)
Adjustable pot controls the delay in sensitivity to reverse sense inputs.
This delay in sensitivity prevents the initial motor inrush current from
causing a fault condition. The weight of the gate determines this setting.
CONNECTORS
LIMIT SWITCH (J4)
24 VAC (TB7)

AC: Alternating Current. An electric current or voltage that reverses direction at regular intervals.
Alternate Action: Ability to open and close a fully open gate by using the same open command.
Arc: The area that is swept by a swing gate from fully closed to fully open position.
ATG: Anti-tailgating refers to a method of immediately closing an opening gate behind a vehicle so that
an unauthorized vehicle can not follow the authorized vehicle through the gate.
DC: Direct Current. An electric current of constant value flowing in one direction only.
Dynamic braking: Stopping the gate by activating the forward and reverse windings of the gate
operator motor in each half AC cycle.
Fault: An abnormal condition which causes the gate to stop to protect the gate and the user.
Gate sensitivity: The response of the gate operator to an exerting force to the gate.
Gear Box: A device that changes the speed and power of its driving force (motor).
Inrush current: Initial current drawn into an electrical device due to its capasitive or inductive nature.
Interrupt Bar or Edge: A switch which is installed at the edge of a gate to protect an object which is
situated between the gate and the gate frame.
LED: Light Emitting Diode. LEDs are indicators placed on the controller board which light up to
indicate an action in the system.
Limit switch: A switch which its closure indicates the gate has reached its open or close limit, causing
the gate to stop. There are two limit switches, open and close.
Limit cam: An object which its excursion corresponds to the gate traveling distance and closes the
limit switch at the open or close limit of the gate.
Loop sensor: A wire embedded in the ground for magnetically sensing large metallic objects (cars).
✔ Exit or Open Loop: activation opens the gate.
✔ Interrupt or Reverse or Reopen Loop: activation reverses or stops the gate.
✔ Shadow Loop: activation prevents a fully open or closed gate from moving while a vehicle
is inside the arc of a swing gate.
Loop detector: An electronic device that is activated by a loop sensor sensing a metallic object.
Master/Slave: A synchronized system containing a pair of gate operators.
Maglock: An electric magnet which is used to secure the closed gate.
Power Fail Option: A battery backup system which opens or closes the gate at power outage.
Pulley: A grooved wheel which transfers power via a belt.
Reclose Timer: An electronic timer which closes the fully open gate automatically.
Retry: A condition at which the stopped gate resumes its course automatically after the occurrence of
a Fault.
RPM: Rotation Per Minute is a term to indicate the speed of an rotary object.
Sprocket: A toothed wheel which transfers power via a chain.
Thermal overload: A condition at which a heat producing device shuts off automatically when it
reaches a critical and damaging temperature level.
Torque: A force that causes rotation.
Torque Limiter: A clutch-like mechanism used to relieve excessive torque generated by the gate on
the gate operator.
