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 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 photo 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 (e.g., sirens, horns or buzzers).

NOTES:

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.

Model HS670 meets the following specifications:

UL325 ENTRAPMENT PROTECTION REQUIREMENTS

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 photo-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 swing 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" (57.15 mm) diameter sphere from passing through the openings anywhere in the gate, and in that portion of the adjacent fence that the gate covers in the open position.

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.

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 must be far enough from the gate so that the user is prevented from coming in contact with the gate while operating the controls.

9. Controls intended to be used to reset an operator after 2 sequential activations of the entrapment protection device or devices must be located in the line of sight of the gate, or easily accessible controls shall have a security feature to prevent unauthorized use.

10. All warning signs must be installed where visible, on each side of the gate.

11. For a gate operator utilizing a non-contact sensor: a. See instructions on the 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. 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.

b. 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.

c. One or more contact sensors shall be located at the leading edge, trailing edge and post mounted both inside and outside of a

vehicular horizontal slide gate. d. One or more contact sensors shall be located at the bottom edge of a vehicular vertical lift gate. 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.

OPERATOR WARNINGS

SUGGESTED ENTRAPMENT PROTECTION DEVICE LOCATIONS

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.

WARNING SIGN PLACEMENT

SAFETY PRECAUTIONS FOR OPEN ROLLER GATES AND ORNAMENT “GRILL TYPE” GATES

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.

• Do NOT mount accessories that are accessible through

gate.

• 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' 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'

from the gate or any moving parts of the gate.

NOTES: Installation shown is for a right-handed unit (on right side of gate opening when inside looking out). Left-handed is opposite. For left-handed conversion, see page 17.

If there is suitable existing concrete at area of unit mounting, use dimensioning procedure described in step 1. Conduit locations may require modifications to suit your application.

CONCRETE PAD

1. Layout concrete pad as detailed.

2. Locate conduit, as required, prior to pouring concrete. 3 Pour concrete pad. The pad must be level and above the

ground line. Pad must be a minimum of 24" in depth or below the frost line, whichever is greater.

4. Allow concrete to set at least 2 days before installing unit.

5. Locate (4) 1/2" concrete anchors (not provided ) or other means of fastening as shown. Anchors must be positioned accurately and secure in the concrete.

NOTE: Always use separate conduits for power wiring and control wiring.You may want to install extra conduit for future wiring considerations. For detailed information on the emergency disconnect system, see instructions provided with it. This is only a suggested layout, other pad layouts are possible.

DRIVE RAIL

1. Mark the location to install drive rail 11-1/2" from the top of concrete pad. The drive rail should be the gate opening width plus 3' to 4'. The drive rail must be level and parallel to the gate and operator.

2. Fasten the drive rail securely to the gate and backframe.

IMPORTANT NOTE: Make sure that the drive rail and wheels are aligned properly.

VENT CAP

1. Remove the threaded plug from the pump tank.

2. Install the vent cap.

NOTE: Never run the operator without the vent cap installed.

LIMIT SHOES

NOTE: The limit shoes are slotted, so minor adjustments may be made later for the fine tuning of the fully open and close positions. Also, note that the limit switches themselves may be slightly adjusted up or down.

1. Cut wire ties to release limit switch levers and RPM assembly

to the up right position. These items are held down by wire ties to facilitate for initial gate installation.

2. Manually open the gate to the full position.

3. Locate the open limit switch lever and mark its position.

4. Manually close the gate to the full close position.

5. Locate the close limit switch lever and mark its position on the

drive rail.

6. Manually open the gate about halfway. Measure and drill holes

INSTALLATION

GATE STOPS

1. When properly installed the gate will open or close in approximately 3" to 4" after limit shoe shuts the unit off, the “gate stop” will contact the upper drive wheel stopping the gate.

2. After operator has been installed the limit shoes have been attached to the top of the drive rail, locate and install the (2) “gate stops” to the top of the drive rail.

NOTE: The 7" dimension is a reference. You may have to adjust this slightly for your particular application.

SUSPENSION SYSTEM

1. The suspension system is semi-factory set; simply loosen the

suspension separator bolt completely. This will allow both wheels to pinch the drive rail.

NOTE: It is suggested that the separator bolt be removed and left with unit. If it is not removed, make sure that it can not interfere with suspension system.

2. If more or less pressure is required, adjust both upper and

lower suspension spring lock nuts as desired. Both springs should apply about the same amount of pressure.

IMPORTANT:

If using the LiftMaster drive rail, make sure that the drive rail guide wheel is positioned properly.

It is very important that the suspension system is adjusted properly. This system puts pressure on the drive wheels so they can pinch together on the drive rail. This system also allows the drive wheels to “float” so they can follow any slight misalignment of the drive rail. If the springs are over tightened, it will reduce their life span. But, on the other hand, if they are under tightened, the drive wheels may slip on the drive rail.

MANUAL OPERATION

NOTE: When manually opening or closing the gate, it is not, in the beginning, easy to get the gate started. Since fluid has accumulated in the drive motors, it may take more force to get the gate started.

The pump is equipped with a manual bypass valve. By positioning the valve handle down (manual operation), the gate can be manually opened or closed.

NOTE: A back-up to this is the suspension separator bolt. By tightening this bolt, the drive wheels will be pushed off by the drive rail.

ADJUSTMENT

To reduce the risk of SEVERE INJURY or DEATH:

• Disconnect power BEFORE performing ANY adjustments.

WARNING

HALL EFFECT SENSOR ADJUSTMENT

NOTE: Normally the hall effect sensor 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 hall effect sensor. It may become necessary to adjust the sensor for correct alignment. To do so please perform the following steps:

1. The hall effect sensor must be centered over the magnet.

Adjust with horizontal screws.

2. The hall effect sensor must be level.

3. The hall effect 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.

FORCE ADJUSTMENT

MOTOR LEARN FUNCTION (FORCE PROFILE)

This function is preprogrammed at factory. If either board or motor is replaced, the controller will need to be programmed to “LEARN” the specific motor RPM profile of your operator. Switch “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. Detach the unit from the gate, the motor needs to be learned

without a load. (Do not use the manual release, the limit shaft must be turning during learn sequence.)

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.

4. Reconnect the unit to the gate, reset the limits and adjust the

force control.

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 page 16.

DUAL GATE COMMUNICATIONS

The controller 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 TB11 and TB12. 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.

PROGRAMMING THE RADIO RECEIVER

SET SECURITY MODE

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.

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 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.

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.

PROGRAMMING THE REMOTE TO THE RECEIVER

1. Pry open the front panel of receiver case with a coin or a screwdriver. Re-connect power to operator (Figure 3).

2. Press and release the "learn" button on the receiver. The learn indicator light will glow steadily for 30 seconds.

3. Within 30 seconds, press and hold the button on the hand-held remote that you wish to operate your gate operator.

The opener will now operate when the push button on either the receiver or the remote control is pressed.

Repeat Steps 2 and 3 for each remote control that will be used to operate the gate operator.

TO ERASE ALL REMOTE CONTROL CODES

Press and hold the “learn” button on the receiver panel until the indicator light turns off (about 6 seconds). All remote codes are now erased. Then follow the steps above to reprogram each remote control.

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 the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

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.

SEQUENCED ACCESS MANAGEMENT SYSTEM (SAMS)

SAMS DEFINITION

The Sequenced Access Management System or SAMS allows the customer more control when managing vehicular entrances to areas such as industrial complexes, businesses and airports. 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 GL board’s Interrupt Loop input. Once the device activates the Interrupt Loop input, the next vehicle to access the SAM system will lock the gate in the open position until the device deactivates. When the device deactivates, the timer to close will automatically close the gate.

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.

SAMS WIRING

1. Install conduit between the BG770 and the HS670 for SAMS control wiring.

2. Run a 4-conductor cable in the conduit between the BG770 HS670.

3. Locate the SAMS relay terminals (J5) on the GL board in the HS670 and locate the auxiliary limit switch in the BG770.

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

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

6. Attach a wire from terminal TB5 to the common (COM) on the auxiliary limit switch in the barrier gate.

7. Attach a wire from terminal TB8 to the normally open (NO) on the auxiliary limit switch.

8. Test for correct functionality of the SAM system.

OPTIONAL CONTROL DEVICES

ACCESSORY WIRING

STOP/RESET AUXILIARY CONTROL WIRING Terminals 6 & 5 (Com) - Open

These terminals are intended for use as a general open control. Accessories that may be wired to this input include: Telephone Entry Systems, Radio Receiver (Commercial Applications), Exit Loop Detector, Keypads, 7-Day Timer. Note: Will not override a

double entrapment (signalled by the gate stopped and entrapment alarm on).

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

These terminals are intended for use only with the open control of a three-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 three-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 GL operator controller board senses commands using +24VDC from terminal #3. Commands are seen when +24VDC are applied to the controller’s input terminals. NOTE: The GL

controller has built in surge suppression circuitry however please take precautions when adding any additional surge protection.

Terminals 1 & 5 (Com) - Single Button Input

These terminals are intended for use with a radio receiver in a residential application or as a single button control. This allows the user to open the gate by activating the transmitter when the gate is closed or between limits. This input also gives the user the ability to close the gate by activating the transmitter when the gate is on the open limit.

Terminals 3 & 5 (Com) - Stop/Reset Control Input These terminals are intended for use with a single stop/reset button or the stop control of a three-button station that is installed within line of site of the gate. This input functions to stop the gate or to reset the gate after an entrapment fault. Note: This input uses a normally closed circuit and the operator will not run until a stop control is installed. NOTE: It is strongly

recommended that a jumper be used for testing purpose only and not for normal operation.

➤ Check the green LED (D17) on GL 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 14.

➤ 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 loop LED is on, make sure factory plug-in loop

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

➤ 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 12 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 secondary voltage power is bad, check to make sure the circuit fuse is not blown and that the correct primary tap is used on the transformer. If fuse and tap are correct replace the transformer.

➤ Stand-alone Operators: Make sure there is a jumper installed across

TB11 and TB12.

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

installed correctly and is intact (not damaged).

➤ 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 GL board. If all is good, replace GL 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 12 of this manual.

1) Low primary (high voltage) power

2) Problem in the motor

3) Problem in the contactor

4) Rail slippage

➤ 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 12 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). Relace the contactor.

➤Observe the drive wheels as they move the gate. If the wheels slip on

the rail, tighten the compression springs until the rail no longer slips.

FAULT POSSIBLE CAUSE FIX

MASTER OR SECOND OPERATOR IS NOT FUNCTIONING PROPERLY

OPERATOR RUNS BUT THEN STOPS AND REVERSES DIRECTION

MOTOR RUNS BUT GATE DOES NOT MOVE; OPERATOR STOPS AND ALARMS

OPERATOR OPENS IMMEDIATELY UPON POWER UP AND DOES NOT CLOSE

OPERATOR HAS TROUBLE LEARNING THE MOTOR

PROGRAMMING CHANGES DO NOT EFFECT THE GATE

GATE EDGE PAUSES GATE WHEN STRUCK DURING OPENING

GATE DOES NOT ACTIVATE TIMER TO CLOSE AFTER THE CLOSE PHOTO EYE IS BROKEN

RADIO CONTROLS WILL NOT CLOSE THE GATE FROM THE OPEN LIMIT

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

TROUBLESHOOTING

➤ 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 on page 18 and check both the master and

second for proper programming.

1) Entrapment (force pot) incorrectly set

2) Gate is binding or not running smoothly

3) Rail slippage

4) Brake is not functioning properly

5) Observe red LEDs D29 and D31

6) Hall Effect Sensor is not aligned/adjusted correctly

➤ 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.

➤ Observe the drive wheels as they move the gate. If the wheels slip on

the rail, tighten the compression springs until the rail no longer slips.

➤ 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 GL 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 engaged.

2) Operator’s main power is out of phase (three phase only).

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

manual release, when disengaged, will set off the entrapment sensor if the gate is given a command to move. See page 11.

➤ 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 13.

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 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 the unit’s manual release is not engaged. The unit’s

manual release, when engaged, will not allow the entrapment sensor to provide feedback to the GL 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 18 and reprogram the obstruction inputs for correct operation.

1) Close obstruction input is programmed incorrectly

➤ The close obstruction input has been programmed to function with

gate edges, not photo eyes. Refer to page 18 and reprogram the obstruction inputs to match the accessories that are installed on operator.

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

Configure terminals R1-4 for single button radio function by performing the following modification:

➤ Locate and disconnect the end of the wire running to terminal J1-6

from R4.

➤ Connect the end of the wire removed from terminal J1-6 to terminal

J1-1. Refer to pages 30 and 31.

(A) BYPASS VALVE:

It MUST be in the “automatic” position (horizontal). If it is in the manual position, no fluid gets to the drive motors, so they won’t turn. If the bypass lever is between positions, fluid will be bled off, so motors will turn slower.

(B) PUMP:

Air may be in the system, allow about 15 seconds for air to dissipate. Filter may be clogged. Check fluid level.

Press and hold the manual override button on valve. If unit works okay, check valve for proper wiring. See page 31.

(D) HOSES:

Double-check hose routings between pump and motors. If wrong, fluid will flow in the wrong direction. Check for leaks and/or pin holes.

(E) FITTINGS:

Tighten if required. See page 29.

(F) CHECK VALVE: See page 29. (G) SEALS: (H) RELIEF VALVE: See page 29. (I) FLUID: Check fluid level in tank. (J) THREE PHASE MOTOR MISWIRED

TROUBLESHOOTING

HYDRAULIC SYSTEM INFORMATION

FLUID

1. If and when adding fluid, use ONLY hydraulic oil.

2. The tank capacity is: one (1) gallon maximum.

3. To measure the fluid in the tank, it is suggested that a ruler be used like a dip stick. Insert it into the tank until it touches the bottom, then remove. When tank is full, the fluidmark should be around six inches.

DO NOT let the fluid level get below 3 to 4 inches.

PUMP

The pump on the HS670 has a built in relief valve. If the P.S.I. should exceed its factory setting, it will bleed off the excess. The HS670-100 is set at approximately 600 P.S.I. the HS670-200 is set at approximately 1500 P.S.I.

1. Both models have a 4 way, 3 position, dual solenoid activated directional valve. It operates on 24 VDC, with a built-in rectifier on each solenoid. Reference hydraulic circuit.

2. Both models have a bypass valve with handle. When this valve is positioned for manual operation, it will redirect the fluid back into the tank and not through the motors. Reference hydraulic circuit.

3. Both models have a check valve built into the pump. This valve will not allow fluid to go in the wrong direction. Reference hydraulic circuit.

HYDRAULIC CIRCUIT

HYDRAULIC DON’TS

1. DO NOT use only one wrench to lighten hose swivel fittings. Use two wrenches, one to tighten and one to hold back opposite fitting. See illustration above.

2. DO NOT pour detergent oil, mineral spirits, diesel fuel, fuel oil or gasoline into the tank. NEVER USE BRAKE FLUID. Only use hydraulic oil.

3. DO NOT put pipe dope or teflon tape on any part of hose fittings.

4. DO NOT remove vent cap except to fill tank with fluid.

5. DO NOT attach hoses to fittings that have dirt on them. Clean hoses, fittings and fitting seats carefully.

HOSES REMOVAL

NOTE: Wear adequate eye protection when performing this step.

To minimize loss of fluid when removing hoses, remove power, position bypass valve to manual operation, and press and hold directional valve manual override for about 30 seconds.

You will need to insert a small tool into hole and push, to activate manual override.

HYDRAULIC PUMP DIRECTIONAL VALVE CONNECTORS
