CLASS I – RESIDENTIAL VEHICULAR GATE OPERATOR

A vehicular gate operator (or system) intended for use in a home of one-to four single family dwellings,
or a garage or parking area associated therewith.

CLASS II – COMMERCIAL/GENERAL ACCESS VEHICULAR GATE OPERATOR

A vehicular gate operator (or system) intended for use in a commercial location or building such as a
multi-family housing unit (five or more single family units) hotel, garage, retail store or other building
servicing the general public.

CLASS III – INDUSTRIAL/LIMITED ACCESS VEHICULAR GATE OPERATOR

A vehicular gate operator (or system) intended for use in a industrial location or building such as a
factory or loading dock area or other location not intended to service the general public.

CLASS IV – RESTRICTED ACCESS VEHICULAR GATE OPERATOR

A vehicular gate operator (or system) intended for use in a guarded industrial location or building such
as an airport security area or other restricted access locations not servicing the general public, in which
unauthorized access is prevented via supervision by security personnel.

SAFETY ACCESSORY SELECTION

All UL325 compliant LiftMaster gate operators will accept external
entrapment protection devices to protect people from motorized
gate systems. UL325 requires that the type of entrapment
protection correctly matches each gate application. Below are the
six types of entrapment protection systems recognized by UL325
for use on this operator.

ENTRAPMENT PROTECTION TYPES

Type A: Inherent obstruction sensing system, self-contained

within the operator. This system must sense and initiate
the reverse of the gate within two seconds of contact
with a solid object.

Type B1: Connections provided for a non-contact device, such as

a photoelectric eye, can be used as a secondary
protection.

Type B2: Connections provided for a contact sensor. A contact

device, such as a gate edge, can be used for secondary

protection.
Type C: Inherent adjustable clutch or pressure relief valve.
Type D: Connections provided for a control

requiring continuous pressure to

operate the operator open and close.
Type E: Built-in audio alarm. Examples

include sirens, horns or buzzers.

NOTE: UL requires that all installations must
have warning signs placed in plain view on
both sides of the gate to warn pedestrians of
the dangers of motorized gate systems.

UL325 ENTRAPMENT PROTECTION REQUIREMENTS

The chart above illustrates the entrapment protection
requirements for each of the four UL325 classes.

In order to complete a proper installation you must satisfy the
entrapment protection chart shown above. That means that
the installation must have one primary means of entrapment
protection and one independent secondary means of
entrapment protection. Both primary and secondary
entrapment protection methods must be designed, arranged
or configured to protect against entrapments in both the open
and close directions of gate travel.

For Example: For a slide gate system that is installed on a
single-family residence (UL325 Class I) you must provide the
following: As your primary type of entrapment protection you
must provide Type A inherent (built into the operator)
entrapment sensing and at least one of the following as your
secondary entrapment protection: Type B1- Non-contact
sensors such as photoelectric eyes, Type B2- Contact sensors
such as gate edges or Type D- Constant pressure control.

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:

• Gate Edges • Guards for Exposed Rollers • Photoelectric Sensors

• Screen Mesh • Vertical Posts • 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 4' (1.2 m) above

the ground to prevent a 2 1/4" (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. Swinging gates shall not open into public access areas.

7. The gate must be properly installed and work freely in both directions prior to the installation of the gate operator.

8 Controls intended for user activation must be located at least six feet (6') 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.

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, one on each side of the gate where easily visible.

11. For a gate operator utilizing a non-contact sensor:
a. Reference owner’s manual regarding placement of non-contact sensor for each type of application.
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. One or more contact sensors shall be located at the bottom edge of a vehicular vertical lift gate.
c. 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.
d. A wireless contact sensor such as the one that transmits radio frequency (RF) signals to the gate operator for entrapment

protection functions shall be located where the transmission of the signals are not obstructed or impeded by building structures,

natural landscaping or similar obstruction. A wireless contact sensor shall function under the intended end-use conditions.
e. One or more contact sensors shall be located on the inside and outside leading edge of a swing gate. Additionally, if the bottom

edge of a swing gate is greater than 6" (152 mm) above the ground at any point in its arc of travel, one or more contact sensors

shall be located on the bottom edge.
f. One or more contact sensors shall be located at the bottom edge of a vertical barrier (arm).

NOT FOR USE AS PEDESTRIAN PASSAGE! This operator is
intended for vehicular use only. To prevent INJURY to
pedestrians, a separate pedestrian access should be supplied,
visible from the gate. Locate the pedestrian access where there is
not a chance of INJURY at any point during full movement of the
gate.

DO NOT MOUNT ACCESSORIES THAT ARE
ACCESSIBLE THROUGH GATE!

WARNING SIGN PLACEMENT

To prevent SERIOUS INJURY or DEATH from a moving gate:

• Install Warning signs on EACH side of gate in PLAIN VIEW.

• Permanently secure each Warning sign in a suitable manner
using fastening holes.

Moving Gate Can Cause

Injury or Death

KEEP CLEAR! Gate may move at any
time without prior warning.

Do not let children operate the gate or
play in the gate area.

This entrance is for vehicles only.
Pedestrians must use separate entrance

SAFETY PRECAUTIONS FOR OPEN ROLLER GATES

• Injuries occur when people get their hands or feet caught
between the top or bottom of the gate and the gate roller.
These potential pinch-points should be guarded against at
ALL times. Enclosed style gate tracks are available for
refitting of these rollers from many fence suppliers. Also,
roller guards are available for installing over the rollers.

• UL325 requires that, when used, contact sensors shall be
located at the leading edge, trailing edge and be post
mounted both inside and outside of a vehicular horizontal
slide gate. Non-contact sensors such as photo eyes must
protect during both open and close gate cycles.

• Injuries occur when people put their hands and arms
through openings in the grill while the gate is operating.
They cannot retract their arm and it gets caught between the
moving gate grill and the stationary fence post or fence. This
potential hazard can be averted by placing a 4' (1.2 m)
screen mesh on the gate to prevent access through openings
anywhere the gate may travel. See Safety Brochure for
details. To prevent entrapment injuries, mount controls at
least 6' (1.8 m) from the gate or any moving parts of the
gate.

angles configured out (Figure 1). If you have pad constrictions,
either angle can be unbolted and reversed to ‘angle in’.

NOTE: If you are replacing an SL540/SL570 and wish to use the
same pad mounting hardware, the gate side mounting angle must
be installed angle in.

NEW INSTALLATION

Concrete Pad Preparation:

1. Lay out concrete pad. (Figure 2).

2. Locate electrical conduit, as required, prior to pouring
concrete.

3. Pour concrete pad.

4. Secure operator (Figure 3) to the concrete pad using four 1/2"
concrete anchors (not provided).

1. Mount gate brackets to the vertical front and rear posts of the
gate (Figure 1).

2. Remove the operator cover.

3. Locate and engage the manual disconnect and lock it in place
(refer to page 14).

4. Connect chain take-up bolt to the end of the chain and attach
to the rear gate bracket (Figure 2).

5. Ensure that the drive and idler sprockets are in line with each
other. Thread the chain through the plastic chain guide, around
drive and idler sprockets, and then through the second plastic
chain guide toward front gate bracket (Figure 3).

6. Adjust the chain to proper length and attach second take-up
bolt to chain end. Secure the take-up bolt to the front gate
bracket as shown.

Adjust nuts on chain take-up bolts to remove chain slack. A
general rule of thumb is to leave a maximum of 1" (2.5 cm) of
chain slack for every 10' (3 m) of chain length.

Do not overtighten chain.

NOTE ABOUT SOME TYPES OF CANTILEVER GATES:

With some cantilever gates over 20' (6 m) long, you may need to
add a brace along the length of the gate to prevent the gate from
bowing when chain is tightened. This may also be required on
some styles of gates that are constructed out of aluminum. If
positioned properly, this brace can also be used as a chain
support.

WARNINGWARNING

WARNING

RPM SENSOR (HALL EFFECT) ADJUSTMENT

NOTE: Normally the RPM Sensor (hall effect) does not need
adjustment, but may go out of alignment due to shipping
vibration or rough handling.

These operators use an internal entrapment protector system.
This system consists of the control board, magnet, and
RPM sensor (hall effect). It may become necessary to adjust the
sensor for correct alignment. To do so please perform the
following steps:

1. The sensor must be
centered over the magnet
wheel. Adjust with
horizontal screws.

2. The sensor must be
level.

3. The sensor air gap
should be adjusted to
.010 - .015 of an inch.
(The thickness of a
business card may be
used to gauge the
correct distance.) Adjust
with vertical screws.

PROGRAMMING THE RADIO RECEIVER

Set Security Mode

The Universal Receiver can be used with up to 15 rolling code
remote controls or passwords in HIGH security mode. Alternately,
it can be used with up to 31 of any type remote control in
NORMAL security mode, including any combination of rolling
code, billion code, or dip switch remotes.

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 1).

When changing from NORMAL to HIGH security mode, any
previous remote control codes must be erased. Repeat Steps 2
and 3 in the Programming Section below to reprogram the
receiver for each remote control remote control in use.

The receiver is factory set at HIGH.

Set Output Duration

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 2).

The receiver is factory set at M.

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
controls.

• Activate gate or door ONLY when it can be seen clearly, is
properly adjusted and there are no obstructions to door travel.

• ALWAYS keep gate or garage door in sight until completely closed.
NEVER permit anyone to cross path of moving gate or door.

ACCESSORY WIRING (CONTINUED)

Terminals 7 & 5 (Com) - Hard Open Override Control Input

These terminals are intended for use only with the open control
of a 3-button station that is installed within line of sight of the
gate. A momentary activation of this input will cause the gate to
open. Activation of this input for longer than three seconds will
enable the control to be used as a constant pressure override
device. This will allow the user, in emergencies, to override a
failed accessory such as a loop detector or photo-eye.

Terminals 4 & 5 (Com) - Close Override Control Input

These terminals are intended for use only with the close control
of a 3-button station that is installed within line of sight of the
gate. A momentary activation of this input will cause the gate to
close. Activation of this input for longer than three seconds will
enable the control to be used as a constant pressure override
device. This will allow the user, in emergencies, to override a
failed accessory such as a loop detector or photo-eye.

Terminals 8 & 5 (Com) - Interrupt (Safety) Loop Input

These terminals are intended for use with a loop detector. This
input functions to reverse a closing gate to the open limit.
Latching this input will reset the timer to close.

Terminals 2 & 5 (Com) - Shadow Loop Input

These terminals are intended for use with a loop detector and is
primarily used on swing gate operators. This input protects cars
by preventing the gate from moving off of the open or close limit
when the shadow loop input is active.

The control board senses commands using +24Vdc from terminal
#3. Commands are seen when +24Vdc is applied to the
controller’s input terminals. NOTE: The control board has built in

surge suppression circuitry however please take precautions
when adding any additional surge protection.

MASTER/SECOND SYSTEMS
Dual Gate Communications

The control board is capable of running the operator in a master
or second mode depending on (S4) switch setting.

Before initiating any command the master unit queries for the
presence of a “second unit” for a time period of one second. If
the master gets no response the operator will operate in a stand
alone mode. NOTE: For single unit applications, a jumper must be

placed between 11 and 12 of the field wiring terminal block. In
this mode no further communications will take place during
travel. If the master detects the presence of a second unit the
master will continue to query the second unit during travel. The
second unit will send a response to the master for every query.
The second operator will stop if there is a period of one second
or more of no communications.

When two operators are connected in dual gate configuration
accessories may be connected to either the master or second.

NOTE: Do not run Master/Second communication wiring in the
same conduit as the power and control wiring. The Second unit
will require a normally close stop circuit for proper system
operation. After Master/Second wiring has been completed and
the S4 switch programmed, both units must have their power
cycled to initiate proper Master/Second communication. The
motor learn function must be completed in stand alone mode
prior to Master/Second wiring.

EARTH GROUND ROD INSTALLATION

Proper grounding gives an electrical charge, such as from an
electrical static discharge or a near lightning strike, a path from
which to dissipate its energy safely into the earth.

Without this path, the intense energy generated by lightning could
be directed towards the gate operator. Although nothing can
absorb the tremendous power of a direct lightning strike, proper
grounding can protect the gate operator in most cases.

The earth ground rod must be located within 3 feet from the gate
operator. Use the proper type 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 should cut the ground
wire too short, break it, or destroy its integrity, replace it with a
single wire length.

Single piece of 12
gauge copper wire
attached to the
operator’s chassis

To AVOID damaging gas, power or other underground utility
lines, contact underground utility locating companies
BEFORE digging more than 18" (46 cm) deep.

Check local

codes for

proper depth.

WARNINGWARNING

WARNING

SAMS OPERATION

1. When an authorized vehicle accesses the gate system, the

SAM system responds by first opening the gate farthest from
the vehicle, the swing or slide gate.

2. Once the swing or slide gate is open, the barrier gate begins

its open cycle.

3. Once the barrier is open the vehicle may pass through the

SAM system. At this point you have two options in how you
would like to initiate the SAM systems closure. You may
chose to:

a) Use a timer to close system to automatically close the

barrier gate after a preset amount of time or

b) Use a loop system to close the barrier gate after the vehicle

has passed through the SAM system.

4. Once the barrier gate is closed the slide or swing gate will

activate its internal timer to close and begin closing.

5. If another authorized vehicle accesses the SAM system before

the slide or swing begins to close the barrier will open and
allow the vehicle to pass through the SAM system.

6. If another authorized vehicle accesses the SAM system during

the slide or swing gates closing cycle the SAM system will
reopen the slide or swing gate. Once the slide or swing gate
reaches the open position the barrier will then open to allow
the vehicle to pass through the SAM system.

7. If no other authorized vehicles access the SAM system the

swing or slide gate will close followed by the barrier.

SEQUENCED ACCESS MANAGEMENT SYSTEM (SAMS)

The Sequenced Access Management System or SAMS allows the customer more control when managing vehicular entrances to areas
such as apartment complexes, businesses and gated communities. The basic concept of the system is that traffic is controlled by two
gates installed in tandem, a fast moving gate such as a barrier gate operator and a slower moving more secure or ornamental gate
such as a single or pair of slide/swing gate operator. The design of this gate system balances the demands of speed during high traffic
periods with security during low traffic periods. Barrier gates typically have the fastest open times of the many gate operator types and
the slide or swing gates allow you to effectively seal off the perimeter of the complex you are planning to secure.

NOTE: Connect all entry devices to the slide or swing gate. If using a device, such as a 7-day timer, to latch the slide or swing gate
open during high traffic times, connect the device’s N/O relay output to the control board’s Interrupt (Safety) Loop input. Once the
device activates the Interrupt (Safety) Loop input, the next vehicle to access the SAMS system will lock the gate in the open position
until the device deactivates. When the device deactivates, the timer to close will automatically close and secure the gate.

SAMS WIRING

1. Install conduit between the BG770 and the SL575 for SAMS
control wiring.

2. Run a 4-conductor cable in the conduit between the BG770
SL575.

3. Locate the SAMS relay terminals (J5) on the control board in
the SL575 and locate the auxiliary limit switch in the BG770.

4. Attach a wire from the SAMS relay terminal (J5) on the control
board to terminal 1 on the BG770 terminal strip.

5. Attach a wire from the SAMS relay terminal (J5) on the control
board to terminal 3 on the BG770 barrier gates terminal strip.

6. Attach a wire from terminal 5 of the SL575 accessory wiring
terminal block to the common (COM) on the auxiliary limit
switch in the barrier gate.

7. Attach a wire from terminal 8 of the SL575 accessory wiring
terminal block to the normally open (NO) on the auxiliary
limit switch.

8. Test for correct functionality of the SAM system.

2. Inspection and service should always be performed anytime a
malfunction is observed or suspected.

3. Limit switches may have to be reset after any major drive
chain adjustments.

4. If lubricating chain, use only a proper chain lube spray or a
lightweight motor oil. Never use grease or silicone spray.

5. When servicing, please do some “house cleaning” of the
operator and the area around the operator. Pick up any debris
in the area. Clean the operator as needed.

6. 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
(+ or -)of the operators rating.

IMPORTANT SAFETY INSTRUCTIONS

To reduce the risk of SEVERE INJURY or DEATH:

1. READ AND FOLLOW ALL INSTRUCTIONS.

2. NEVER let children operate or play with gate controls.
Keep the remote control away from children.

3. ALWAYS keep people and objects away from the gate.
NO ONE SHOULD CROSS THE PATH OF THE MOVING
GATE.

4. Test the gate operator 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 INJURY or DEATH.

5. Use the emergency release ONLY when the gate is not
moving.

6. KEEP GATES PROPERLY MAINTAINED. Read the
owner’s manual. Have a qualified service person make
repairs to gate hardware.

7. The entrance is for vehicles ONLY. Pedestrians MUST
use separate entrance.

8. Disconnect ALL power BEFORE performing ANY
maintenance.

9. ALL maintenance MUST be performed by a LiftMaster
professional.

SOLENOID ACTUATED BRAKE

The brake is adjusted at the factory and should not need
additional adjustments for the the life of the friction pad.

Replace friction pads when necessary. Refer to the illustration for
identification of components for the solenoid type brake system.

FRICTION CLUTCH

1. Remove cotterpin from nut on the clutch shaft.

2. Back off clutch nut until there is very little tension on the
clutch spring.

3. Tighten clutch nut gradually until there is just enough tension
to permit the operator to move the gate smoothly but to allow
the clutch to slip if the gate is obstructed. When the clutch is
properly adjusted, it should generally be possible to stop the
gate during travel.

4. Reinstall Cotterpin.

The friction clutch system is not an automatic reversing device. It
only serves to minimize damage to the gate operator and gate,
and to help minimize vehicle damage. If you need an external
automatic obstruction sensing device, items such as gate edges
and photo beams are available.

CONTROL BOARD PROGRAMMING AND FEATURES

MOTOR LEARN FUNCTION (FORCE PROFILE)

This function is preprogrammed at factory. If either board or
motor is replaced, the control board will need to be
reprogrammed to “LEARN” the specific motor RPM profile of
your operator, the red button “S3” is provided for this. This is
important for accurate force control. Failure to do so may result
in improper and unsafe operation.

NOTE: Motor Learn must be performed in stand alone mode.

1. Ensure that the operator remains attached to the gate
throughout the entire process.

2. Press the motor learn button. The yellow LED should start to
flash rapidly.

3. Push and hold down either the open or the close buttons. The
motor will run for a few seconds and then stop. If the LED
goes out the motor is learned. If the unit activates a limit
before completing the learn or some other error occurs the
LED will go back to on continuously. If this happens try
learning while running in the opposite direction.

To reduce the risk of SEVERE INJURY or DEATH:

• Disconnect power BEFORE performing ANY adjustments.

FORCE CONTROL

Set the force control pot such that the unit will complete a full
cycle of gate travel but can be reversed off an obstruction without
applying an unreasonable amount of force. On most operators
this will be around the middle of the range.

NOTE: For LED location refer to illustration on previous page.

DIAGNOSTICS (LEDS AND CODES)

There are three diagnostic LEDs. Two red LEDs (OLS, CLS) are
indicators for the open and close limits. The LEDs are illuminated
when the limit switch contacts are closed.

The third amber LED (DIAG) is used to blink out diagnostic
codes. The number is the count of the number of times the LED
is on in an 8 second period. The LED is on for approximately 1/2
second and repeats every second until the number is reached.
There will be a pause following each pulse cycle (1-6 pulses) to
differentiate between the different diagnostic codes.

4) Improper J4 connector wiring
(master/second)

5) Low or no high voltage power

6) Low or no low voltage power

7) No LEDs illuminated on the

TROUBLESHOOTING

➤ Check the green LED (D17) on control board. If the green LED is off, check to

make sure a stop control has been installed across terminals TB1-3 and TB1-5
of the terminal strip.

➤ If the yellow LED blinks six times, there is a master/second unit

communication failure. If operator is a single unit, make sure there is a jumper
across terminals TB1-11 and TB1-12. If operator is in a dual gate
configuration, make sure that the communication wiring between the two units
is undamaged and complete.

➤ If the yellow light is solid, the board needs to learn the motor. Follow the

directions on page 22.

➤ If any red LEDs are on, check the corresponding input. An installed accessory

may be wired incorrectly or malfunctioning. Remove the accessory and test
the operator.

➤ If the open or interrupt (safety) loop LED is on, make sure factory plug-in loop

detectors are working properly and appropriate loops are installed on the loop
input terminals.

➤ Stand-Alone Operators: Make sure there is a jumper installed across the J4

connector.

➤ Master/Second Operation: Make sure that the master/second wiring is installed

correctly and is intact (not damaged).

➤ Measure the incoming voltage at the unit’s on/off switch. It should be within

5% of the operator’s rating when running. Make sure that the proper wire
gauge was used for the distance between breaker and operator by consulting
the wiring specifications section on page 8 of this manual.

➤ Measure the voltage at terminals R1 and R2 in the operator. This voltage

should be within 5% of 24Vac. If the high voltage power is good and the low
voltage power is bad, check to make sure the circuit fuse is not tripped and
that the correct primary tap is used on the transformer. If fuse and tap are
correct, replace the transformer.

➤ If both primary and secondary power is good, check to make sure that the J2

connector is making good contact with the pins on the control board. If all is
good, replace the control board.

1) Transformer’s secondary is overloaded

2) Low primary (high voltage) power

➤ Remove all accessory devices and test the operator. If the contactor stops

chattering, find an alternate power source for some of the devices.

➤ Measure the incoming line voltage at the unit’s on/off switch. It should be

within 5% of the operator’s rating when running. Make sure that the proper
wire gauge was used for the distance between breaker and operator by
consulting the wiring specifications section on page 8 of this manual.

1) Low primary (high voltage) power

2) Problem in the motor

3) Problem in the contactor

4) Problem in the brake system

➤ Measure the incoming line voltage at the unit’s on/off switch as well as the

meter base or sub panel. Make sure there is not a major change in voltage.
The voltage at the operator should be within 5% of the operator’s rating when
running.

➤ Check the number of amps currently being drawn from the panel. Make sure

that the total power being drawn does not exceed the panel’s rating.

➤ Make sure that the proper wire gauge was used for the distance between

breaker and operator by consulting the wiring specifications section on page 8
of this manual.

➤ Perform a visual inspection of the motor. Examine the motor’s labels for any

distortion or signs of overheating. Replace the motor if it is humming,
grinding or making excessive noise. NOTE: Repeated motor problems indicate

poor primary power.

➤ Examine the contactor for sparking, smoke or burn marks. Remove the wires

from one side of the contactor, then measure the contact points for high
resistance (above 1 ohm). Replace the contactor.

➤ Make sure that the brake is disengaging when the contactor pulls in and

engaging when the contactor releases. Replace solenoid.

FAULT POSSIBLE CAUSE FIX

1) Failure to cycle power after setup

2) Communication wiring may be damaged or
improperly wired for dual gate operation

3) Master or second unit is not programmed
correctly

4) Master/second connection not properly
grounded

➤ The power to each unit must be cycled in order to initiate proper

master/second communication if the operators were previously in stand-alone
mode.

➤ Make sure that the communication wire that is used is twisted pair and not

run in the same conduit with any power wiring. Failure to do so will result in
interference across the master/second communication line.

➤ Review program settings page 19 and check both the master and second for

proper programming.

➤ Review wiring detail for master/second systems on page 20.

TROUBLESHOOTING

1) Operator’s main power is out of phase
(three phases only)

2) Operation directional switch

➤ Turn off the unit’s main power at the breaker and swap any two power leads at

the operator’s main power switch. Apply power and retest the operator. See
important note on page 12

➤ Check right/left operation switch. See DIP switch S1 programming setting.

1) Entrapment (force pot) incorrectly set

2) Gate is binding or not running smoothly

3) Clutch is not adjusted properly

4) Brake is not functioning properly

5) Observe red LEDs D29 and D31

6) RPM (Hall Effect) Sensor
is not aligned

➤ This pot must be set so that the gate will run smoothly normally and reverse

when encountering an obstruction.

➤ Disengage the manual release and roll gate open and close by hand at normal

operating speed. Make sure that the gate runs smoothly and does not bind. If
the gate is hard to move or binds, repair the gate.

➤ Adjust the clutch so that the operator can move the gate throughout its travel

without slipping but will slip when the gate hits an obstruction.

➤ Make sure that the brake operates correctly. The brake should disengage when

the contactor activates and engage when the contactor releases.

➤ Both LEDs will indicate the activation of entrapment protection devices on

terminals TB1-9 and TB1-10 on the control board. Remove the devices and
retest. If the operator now runs without fault, check those accessories as well
as their wiring.

➤ Make sure that the sensor is adjusted so that it is centered over the limit

shaft’s magnet and is 10-15 thousandths of and inch (business card
thickness) from the magnet.

➤ Replace the sensor if it is adjusted correctly but continues to fail.

1) Operator’s manual release is not aligned

2) Clutch is not adjusted properly

3) V-Belt Slippage

➤ Make sure that the unit’s manual release is not engaged. The unit’s manual

release, when engaged, will set off the entrapment if the gate is given a
command to move.

➤ Adjust the clutch so that the operator can move the gate throughout its travel

without slipping but will slip when the gate hits an obstruction.

➤ Check belt for excessive wear. Belt can be adjusted by loosening the

(4) mounting bolts securing motor to the frame and sliding motor until belt
is taut.

1) Active or malfunctioning accessory check

the red input status LEDs, D11-D13

➤ If any red LEDs are on, check the corresponding input. An installed accessory

may be wired incorrectly or malfunctioning. Remove the accessory and test
the operator.

➤ If the soft open or interrupt (safety) loop LED is on, make sure factory plug-in

loop detectors are working properly and appropriate loops are installed on the
loop input terminals.

1) Operator’s manual release is engaged ➤ Make sure the manual release is not engaged. The operator’s manual release,

when engaged, will not allow the entrapment sensor to provide feedback to
the control board when the operator is moving.

1) Check the save switch on switch S1-1 ➤ If the switch S1-1 is in the on position, any subsequent programming

changes will not affect the gate. To make programming changes, switch S1-1
off, make desired changes, and then switch S1-1 on.

1) Open obstruction input is programmed
incorrectly

➤ The open obstruction input has been programmed to function with photo

eyes, not gate edges. Refer to page 15 and reprogram the obstruction inputs
for correct operation.

1) Close obstruction input is programmed
incorrectly

1) Radio terminals R1-4 are factory configured
for commercial radio function

➤ The close obstruction input has been programmed to function with gate

edges, not photo eyes. Refer to page 15 and reprogram the obstruction inputs
to match the accessories that are installed on operator.

➤ Configure terminals R1-4 for residential radio for residential radio function by

performing the following modifications:

1. Locate and disconnect the end of the wire running to terminal 6 (TB6)
from R4.

2. Connect the end of the wire removed from terminal 6 (TB6) to terminal 1
(TB1). Refer to page 19.
