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.

B. PAD AND MOUNT  
Figure 4. Pad and Track Ribbon  
Figure 5. Bolt Down Pattern  
Figure 6. Conduit Entrance Areas  
1. 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).  
2. 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.  
3. 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).  
4. Be sure to provide access for wiring conduits (Figure 6).  
5. Track installation should be on concrete, not asphalt, and should be at least 10” wide  
and 6” deep.  
6. A 6” gate overlap at the open end of the gate when closed should be provided.  
7. A 30” gate overlap at closed end of the gate when closed should be provided.  
NOTE: Shading indicates acceptable areas for conduit stub access.

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.

I. SETTING LIMIT CAMS  
The left limit cam is close to the output shaft. The right limit cam is close to the control box  
(see Figure 14).  
Limit cams are adjusted by releasing the cam lock plate, rotating the cams, then reseating  
the cam lock plate. When the adjustment is finished, be sure the cam lock plate is seated  
into the notches of BOTH CAMS.  
Each cam rotation (360°) equals 11” of gate travel. Each notch equals 5/8” of gate travel.  
Figure 14. Limit Cam Setting.  
NOTE: The following procedures are for FRONT drive gates. For MID and REAR  
drive gates, reverse Left Gate and Right Gate procedures.  
1. SETTING RIGHT GATE LIMIT CAMS (gate opens right, as seen from the gate operator  
side)  
1. Make sure that switch S2 is set to the “Right” position.  
2. Turn on gate operator power switch.  
3. Using manual OPEN and STOP, move the gate to its proper open limit position.  
4. Rotate the Left cam until it just barely closes the limit switch.  
5. Using manual CLOSE and STOP, move the gate to its proper closed limit position.  
6. Rotate the Right cam until it just barely closes the limit switch.  
7. Open and close the gate to check the limit cam settings. If required, readjust the limit  
cams until they are set properly.  
2. SETTING LEFT GATE LIMIT CAMS (gate opens left, as seen from inside the property)

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.  
Figure 15. Gate Sensitivity Adjustments Location.  
"OPEN TO RIGHT" ADJUSTMENT PROCEDURES  
Right Gate Motion Adjustment (R69)  
1. Initiate opening the gate.  
2. Wait 4 to 5 seconds, then lightly "tug" against the edge of the gate to simulate an  
obstacle.  
3. If the gate does not stop or back up, reclose gate and adjust the pot slightly  
counterclockwise.  
4. Repeat steps 1-3 until gate stops or backs up when tugged and has the desired  
sensitivity.  
Left Gate Motion Adjustment (R160)  
1. Open the gate fully, then initiate closing the gate.  
2. Wait 4 to 5 seconds, then lightly "bump" the leading edge of the gate to simulate an  
obstacle.  
3. If the gate does not stop or back up, reopen the gate and adjust the pot slightly  
counterclockwise.  
4. Repeat steps 1-3 until the gate stops or backs up when bumped and has the desired  
sensitivity.

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  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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.

O. PROGRAMMING THE RADIO RECEIVER  
SET SECURITY MODE  
WARNING  
The Universal Receiver can be used with up to  
15 rolling code transmitters or passwords in HIGH  
security mode. Alternately, it can be used with up to 31  
of any type transmitter in NORMAL security mode,  
including any combination of rolling code, billion code,  
or dip switch remotes.  
To prevent possible SERIOUS INJURY or DEATH from  
electrocution:  
• Be sure power is not connected BEFORE installing the receiver.  
To prevent possible SERIOUS INJURY or DEATH from a moving  
gate or garage door:  
• ALWAYS keep remote controls out of reach of children. NEVER  
permit children to operate, or play with remote control  
transmitters.  
• Activate gate or door ONLY when it can be seen clearly, is  
properly adjusted, and there are no obstructions to door travel.  
The jumper must be set at the HIGH position for the  
receiver to operate in HIGH security mode. It must be  
set at NORMAL position to operate at the NORMAL  
mode. (Figure 19)  
• ALWAYS keep gate or garage door in sight until completely closed.  
NEVER permit anyone to cross path of moving gate or door.  
When changing from NORMAL to HIGH security  
mode, any previous transmitter codes must be erased.  
Repeat Steps 2 and 3 in the Programming Section  
below to reprogram the receiver for each remote  
control transmitter in use.  
NOTICE: To comply with FCC and or Industry Canada (IC) rules, adjustment or  
modifications of this receiver and/or transmitter are prohibited, except for changing the  
code setting or replacing the battery. THERE ARE NO OTHER USER SERVICEABLE PARTS.  
Tested to Comply with FCC Standards FOR HOME OR OFFICE USE. Operation is subject to

To prevent possible SERIOUS INJURY or DEATH, the use of  
CONSTANT OPERATION on residential openers is PROHIBITED.  
For commercial applications, the receiver can be set  
for either constant or momentary closure on the output  
contacts. Use of constant closure is prohibited on  
residential garage door openers because it overrides  
the safety reversal devices.  
With the jumper in the “M” (Momentary) position, the  
contacts will close for 1/4 second regardless of the  
length of radio transmission. With the jumper in “C”  
(Constant) position, the contacts will stay closed as  
long as the radio continues transmitting. (Figure 20)

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.

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  
MAN CLOSE  
MAN STOP  
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.  
Activation fully closes the gate. Continuous activation holds  
gate closed. MAN CLOSE overrides all controls but MAN STOP,  
MAN OPEN and FIRE.  
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 Anti-  
Tailgating (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.

IF GATE TYPE IS SLIDE OR BARRIER AND ATG IS ON:  
Inside Interrupt Loop:  
Activation/deactivation closes an opening gate. Activation stops a  
closing gate and deactivation closes the gate.  
Outside Interrupt Loop:  
Activation stops a closing gate and deactivation closes the gate.  
INSIDE/OUTSIDE PHOTO-SENSOR (TB3)  
IF GATE TYPE IS SWING OR LINEAR:  
Inside Photo Sensor:  
Activation stops a moving gate and deactivation restarts the gate.  
Outside Photo Sensor:  
Activation stops a closing gate and deactivation restarts the gate.  
IF GATE TYPE IS SLIDE OR BARRIER:  
Inside Photo Sensor:  
Activation stops an opening gate and deactivation restarts the  
gate.  
Outside Photo Sensor:  
Activation stops a closing gate and deactivation restarts the gate.  
INTERRUPT BAR INPUTS (TB11)  
INTERRUPT BAR Activation causes gate to stop and reverse a few inches.  
INS./OUTS. INT. SENSE / SHADOW SENSE / EXIT SENSE (TB12/TB13/TB14/TB15)  
INPUTS  
INSIDE  
INTERRUPT  
Input from an Inside Interrupt loop provides the signal for an  
optional LiftMaster loop detector add-on board. Operation is the  
same as the Interrupt Loop SENSE input, above.  
OUTSIDE  
INTERRUPT  
Input from an Outside Interrupt loop provides the signal for an  
optional LiftMaster loop detector add-on board. Operation is the  
same as the Interrupt SENSE  
Loop input, above.  
SHADOW  
SENSE  
Input from shadow loop provides signal for optional LiftMaster loop  
detector add-on board. Operation is the same as Shadow Loop  
input, above.  
EXIT  
SENSE  
Input from exit loop provides signal for optional LiftMaster loop  
detector add-on board. Operation is the same as Exit Loop input,  
above.  
RADIO INPUT (TB6)

RADIO RECV  
Convenience terminals provide power and contact connection for a  
radio receiver. Activation is the same as CYCLE.  
OBSTRUCTION ALARM (TB17)  
Relay contacts close to provide 24VDC alarm power if the gate has two  
consecutive obstruction faults.  
LOW BATTERY/ NO AC POWER (TB18)  
LOW BATTERY  
Activation fully opens or closes the gate, depending the setting of  
Switch S3.  
NO AC POWER  
Activation registers the date and time of power outages in the gate  
operator transaction buffer.  
24VAC OUTPUT (TB7)  
Terminals provide power (24VAC, 200mA) for peripheral  
devices.  
MAGLOCK INPUT (TB4)  
MAGLOCK  
SLAVE I/O INPUT (TB1)  
SLAVE I/O Input/output terminals are used to control a second gate operator in a  
Master/Slave system.  
Relay contacts close when the gate is fully closed.  
PHONE LINE (J9) Terminals connect the telephone line to the gate operator.  
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 Adjustable pot controls the delay in sensitivity to gate  
(R203)  
obstructions. This delay in sensitivity prevents the initial motor  
inrush current from causing a obstruction fault. The weight of the  
determines this setting.
