UL325 MODEL CLASSIFICATIONS (CON’T)

SAFETY ACCESSORY SELECTION-All UL325 compliant LiftMaster gate opera-

tors will accept external entrapment protectiondevices to protect people from motorized gate sys-tems. UL325 requires that the type of entrapmentprotection correctly matches each gate application.Below are the 6 types of entrapment protection rec-ognized by UL325.

Entrapment Protection Types-Type A: Inherent obstruction sensing system, self-

contained within the operator. This systemmust sense and initiate the reverse of thegate within two seconds of contact witha 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 canbe used for secondary protection.

Type C: Inherent adjustable clutch or pressure reliefvalve.

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.

Additionally UL requires that all installationsmust have warning signs in place to warn pedestri-ans of the dangers of motorized gate systems.Signs and labels are included with each operator.The warning signs should be placed in plain view onboth sides of the gate.

UL325 Entrapment Protection Requirements-The following chart illustrates the entrapment

protection requirements for each of the 4 UL325 classes(For more information on UL325 classes refer to previ-ous page.

In order to complete a proper installation youmust satisfy the entrapment protection chart shownabove. That means that the installation must have oneprimary means of entrapment protection and one inde-pendent secondary means of entrapment protection.Both primary and secondary entrapment protectionmethods must be designed, arranged or configured toprotect against entrapments in both the open and closedirections of gate travel.

For Example:For a gate system that is installed on a single-

family residence (UL325 Class I) you must provide thefollowing: As your primary type of entrapment protectionyou must provide Type A inherent (built into the opera-tor) entrapment sensing and at least one of the followingas 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 INFORMATION1. 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 should be specifically designed for an individual applica-tion.

2. Gate operating system designers, installers and users must take into account the possible hazards associated witheach individual application. Improperly designed, installed or maintained systems can create risks for the user as wellas 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, safe-ty features must be incorporated into every design. Specific safety features include:

Gate Edges Guards for exposed rollers Photo-Electric Sensors Screen Mesh Enclosed Track 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 min- imum of 4 feet (1.2 m) above the ground to prevent a 2 1/4inch (57.15 mm) diameter sphere from pass- ing 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 should be installed on all exposed rollers.

5. The operator is intended for installation only on gates used for vehicles. Pedestrians must be supplied with a sepa-rate access opening.

6. The gate must be installed in a location so that enough clearance is supplied between the gate and adjacent struc-tures when opening and closing to reduce the risk of entrapment.

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 whileoperating the controls.

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

10. All warning signs and placards must be installed where visible in the area 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 whilethe 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 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) One or more contact sensors shall be located at the pinch point of a vehicular vertical pivot gate.

d) 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.

e) 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 wire less contact sensor shall function under the intended end-use conditions.

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 gateroller. This potential pinch-point should be guarded against at all times. Enclosed style gate tracks are avail-able for refitting of these rollers from many fence suppliers. Also, roller guards are available for installing overthe rollers.UL325 requires that, when used, contact sensors shall be located at the leading edge, trailing edge, and post-mounted both inside and outside of a vehicular horizontal slide gate. Non contact sensors such as photo eyesmust 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 operat-ing. They cannot retract their arm and it gets caught between the moving gate grill and the stationary fencepost or fence. This potential hazard can be averted by placing a 4’ screen mesh on the gate to preventaccess through openings anywhere the gate may travel. See Safety Brochure for details.

INSTALATION NOTES:1. Installation shown is for a right-handed unit (onright side of gate opening when inside looking out).Left-handed is opposite. For L.H. conversion, seepage 24.

2. If there is suitable existing concrete at area ofunit mounting, use dimensioning proceduredescribed in step 1. Conduit locations may requiremodifications to suit your application.

STEP 1 CONCRETE PAD:A. Layout concrete pad as detailed.

B. Locate conduit, as required, prior to pouring concrete.

C. Pour concrete, insuring that pad is level and above the ground line. Pad must be a minimum of24 inches in depth or below the frost line, whicheveris greater.

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

E. Locate four (4) ½" threaded anchors (not sup-plied) or other means of fatening as shown. Anchorsmust be posItioned accurately and be secure in theconcrete.

NOTES:1. Always use separate conduits for power wiring andcontrol wiring.

2. You may want to install extra conduit for futurewiring considerations.

3. For detailed information on the emergency discon-nect system, see instructions supplied with it.

4. This in only a suggested layout, other pad layoutsare possible.

INSTALLATION (CONT.)MOUNTING HARDWAREBY OTHERSOPTIONAL

DRIVE RAIL

STEP 3 OPERATOR MOUNTING:A. Remove the outer cover from the operator.

B. Carefully secure the concrete pad with thedrive wheels facing the gate.

IMPORTANT NOTE:The operator must be level and parallel with thegate and drive rail. By loosening the bolts securingthe mounting legs to the unit, the operator can beslightly adjusted towards or away from the rail.Retighten bolts.

CAUTION: Make sure that the drive rail and wheelsare aligned properly.

STEP 2 DRIVE RAILA. The length of the drive rail should be the gate openingwidth plus 3 to 4 feet.

IMPORTANT NOTE: It is very important that the drive be:1. Level and parallel to the gate and operator.2. As close as possible to the 11 1/2” dimension.3. Very securely mounted to the gate and backframe.

STEP 4 VENT CAP:A. Remove the threaded plug from the pump tank andinstall the vent cap in its place.

IMPORTANT: Never run the operator without the vent-cap in place.

13

INSTALLATION

STEP 5 LIMIT SHOES:A. Cut wire wraps to release limit switch levers andRPM assembly to the up right position. These itemsare held down by wire wraps to facilitate for initial gateinstallation.

B. Manually open the gate to the full position.

C. Locate the open limit switch lever and mark its posi-tion.

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

E. Locate the close limit switch lever and mark its posi-tion on the drive rail.

F. Manually open the gate about halfway. Per draw-ings below, measure and drill holes. Mount both limitshoes to underside of drive rail.

IMPORTANT NOTES:The limit shoes are slotted, so minor adjustmentsmay be made later for the fine tuning of the fullopen and close position. Also, note that the limitswitches themselves may be slightly adjusted upor down.

It is highly suggested that gate stops be installedto the gate at the full open and closed positions.(See next sheet for installation instructions).

STEP 6 GATE STOPS:A. When properly installed the gate will open or close in approximately 3 to 4 inches after limitshoe shuts the unit off, the “gate stop” will contactthe upper drive wheel stopping the gate.

B. 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 thetop of the drive rail, as shown.

NOTE:1) The 7 inch dimension is a reference. You may haveto adjust this slightly for your particular application.

15

STEP 7 SUSPENSION SYSTEM:A. The suspension system is semi-factory set; sim-ply loosen the suspension separator bolt completely.This will allow both wheels to pinch the drive rail.

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

B. If more or less pressure is required, adjust bothupper and lower suspension spring lock nuts asdesired. Both springs should apply about the sameamount of pressure.

IMPORTANT:If using the LiftMaster drive rail, make sure that the driverail guide wheel is positioned properly. See below.It is very important that the suspension system is adjust-ed properly. This system puts pressure on the drivewheels so they can pinch together on the drive rail.This system also allows the drive wheels to "float" sothey can follow any slight misalignment of the drive rail.If the springs are over tightened, it will reduce their lifespan. But, on the other hand, if they are under tight-ened, the drive wheels may slip on the drive rail.

INSTALLATION

01-20221F11

STEP 8 MANUAL OPERATION:The pump is equipped with a manual bypass valve. Bypositioning the valve handle down (manual operation),the gate can be manually opened or closed.

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

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

SAMS DEFINITIONThe Sequenced Access Management System or SAMS allows the customer more control when managing vehicular entrancesto areas such as industrial complexes, businesses and airports. The basic concept of the system is that traffic is controlled bytwo gates installed in tandem, a fast moving gate such as a barrier gate operator and a slower moving more secure or orna-mental gate such as a single or pair of slide/swing gate operator. The design of this gate system balances the demands ofspeed during high traffic periods with security during low traffic periods. Barrier gates typically have the fastest open times ofthe many gate operator types and the slide or swing gates allow you to effectively seal off the perimeter of the complex you areplanning 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 swinggate open during high traffic times, connect the device’s N/O relay output to the GL board’s Interrupt Loop input. Once thedevice activates the Interrupt Loop input, the next vehicle to access the SAMS system will lock the gate in the open positionuntil the device deactivates. When the device deactivates, the timer to close will automatically close the gate.

SAMS OPERATION1) When an authorized vehicle accesses the gate system, theSAM system responds by first opening the gate farthest from thevehicle, the swing or slide gate.

2) Once the swing or slide gate is open, the barrier gate beginsits open cycle.

3) Once the barrier is open the vehicle may pass through theSAM system. At this point you have two options in how youwould like to initiate the SAM systems closure. You may choseto:

a) Use a timer to close system to automatically close the barrier gate after a preset amount of time orb) Use a loop system to close the barrier gate after thevehicle has passed through the SAM system.

4) Once the barrier gate is closed the slide or swing gate willactivate its internal timer to close and begin closing.

5) If another authorized vehicle accesses the SAM systembefore the slide or swing begins to close the barrier will open andallow the vehicle to pass through the SAM system.

6) If another authorized vehicle accesses the SAM system dur-ing the slide or swing gates closing cycle the SAM system willreopen the slide or swing gate. Once the slide or swing gatereaches the open position the barrier will then open to allow thevehicle to pass through the SAM system.

7) If no other authorized vehicles access the SAM system theswing or slide gate will close followed by the barrier.

SAMS WIRING1) Install conduit between the BG770 and the HS670 for SAMScontrol wiring.

2) Run a 4-conductor cable in the conduit between the BG770HS670.

3) Locate the SAMS relay terminals (J5) on the GL board in theHS670 and locate the auxiliary limit switch in the BG770.

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

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

6) Attach a wire from terminal TB5 to the common (COM) on theauxiliary 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 DEVICESAll inputs are normally open and momentary, except the stop (N.C.). The following instructions are based uponUL 325, and include recommendations for significant increase in safety.

We strongly recommend that you follow the UL guidelines presented throughout the manual. Refer to instructionsshipped with optional control devices for mounting, wiring, programming and adjustment.

Terminals 1 & 5 - Single Button InputThese terminals are intended for use with a radio receiverin a residential application or as a single button control.This allows the user to open the gate by activating thetransmitter when the gate is closed or between limits. Thisinput also gives the user the ability to close the gate byactivating the transmitter when the gate is on the openlimit.

Terminals 2 & 5 - Shadow Loop InputThese terminals are intended for use with a loop detectorand is primarily used on swing gate operators. This inputprotects cars by preventing the gate from moving off of theopen or close limit when the shadow loop input is active.

Terminals 6 & 5 - Soft OpenThese terminals are intended for use as a general opencontrol. Accessories that may be wired to this inputinclude: Telephone Entry Systems, Radio Receiver (OpenOnly), Exit Loop Detector, Keypads, 7-Day Timer. Note: Will not override a double entrapment (signalled bythe gate stopped and entrapment alarm on).

Terminals 8 & 5 - Interrupt (Safety) Loop InputThese terminals are intended for use with a loop detector.This input functions to reverse a closing gate to the openlimit. Latching this input will reset the timer to close.

Terminals 9 & 5 - Obstruction Open (Edge/ Photo Eye Input)Edge Input: See Programming Section This input will reverse an opening gate to the close limit.Activating this input when the gate is closing will have noeffect. Note: If upon reversal a second seperate obstruc-tion is detected (gate edge or R.P.M. sensor), gate willstop & alarm.

Photo Eye Input: See Programming SectionThis input will pause an opening gate. Once the input (photo eye) is cleared, the gate continues to open. Activating this input when the gate is closing will have no effect.

Terminals 10 & 5 - Obstruction Close (Edge/ Photo Eye Input)Edge Input: See Programming SectionThis input will reverse a closing gate to the open limit. When reaching the open limit the timer to close, if enabled, will be disabled until another command is given.Activating this input when the gate is opening will have noeffect. Note: If upon reversal a second seperate obstruc-tion is detected (gate edge or R.P.M. sensor), gate willstop & alarm.

Photo Eye Input: See Programming SectionThis input will reverse a closing gate to the open limit. This input will not affect the timer to close. Activating this input when the gate is closing will have no effect.

Terminals 3 & 5 - Stop/Reset Control InputThese terminals are intended for use with a single stop/resetbutton or the stop control of a three-button station that isinstalled within line of site of the gate. This input functions tostop the gate or to reset the gate after an entrapment fault.Note: This input uses a normally closed circuit and theoperator will not run until a stop control is installed.

Note: It is strongly recommended that a jumper be used fortesting purpose oly and not for normal operation.

Terminals 4 & 5 - Hard Close Control InputThese terminals are intended for use only with the close con-trol of a three-button station that is installed within line of sightof the gate. A momentary activation of this input will causethe gate to close. Activation of this input for longer thanthree seconds will enable the control to be used as aconstant pressure override device. This will allow the user,in emergencies, to override a failed accessory such as a loopdetector or photo-eye.

Terminals 7 & 5 - Hard Open Control InputThese terminals are intended for use only with the open con-trol of a three-button station that is installed within line of sightof the gate. A momentary activation of this input will causethe gate to open. Activation of this input for longer thanthree seconds will enable the control to be used as aconstant pressure override device. This will allow the user,in emergencies, to override a failed accessory such as a loopdetector or photo-eye.

MOTOR LEARN FUNCTION (FORCE PROFILE)This function is preprogrammed at factory. If either board or motor is replaced, thecontroller will need to be programmed to “LEARN” the specific motor RPM profileof your operator. Switch “S3” is provided for this. This is important for accurateforce control. Failure to do so may result in improper and unsafe operation. Note: The motor learn function must be completed in stand alone mode prior toMaster/Second wiring.

To learn the motor:1. Attatch the unit to the gate, the motor needs to be learned with the rail attached.Make sure the drive wheels supply adequate pressure to move the gate. (Makesure the manual release is not engaged)

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

3. Install a jumper on either the hard open or the hard close input terminals. Themotor will run for a few seconds and then stop. If the LED goes out the motor islearned. If the unit activates a limit before completing the learn or some other erroroccurs the LED will go back to on continuously. If this happens try learning whilerunning in the opposite direction.NOTE: It is important that the jumper is in constant contact while the gate ismoving in learn mode.

4. Recheck the limits and adjust the force control as needed.

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

CONTROLLER PROGRAMMING AND FEATURES

DIAGNOSTICS (LEDS AND CODES)There are three diagnostic LEDs. Two red LEDs(OL, CL) are indicators for the open and close limits.The LEDs are illuminated when the limit switch con-tacts are closed.

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

TROUBLESHOOTING LED’SThere are 9 troubleshooting LEDs (D11, D13, D15,D17, D19, D21, D24, D29, D31).

RELAY DRIVE TROUBLESHOOTING LED’SThere are 5 troubleshooting LEDs (D2, D3, D4, D5,D6) on relay drives K1 through K5. These LEDs willbe illuminated when the microcontroller relay driveis activated.

DUAL GATE COMMUNICATIONSThe controller is capable of running the operator in a master or sec-ond mode depending on (S4) switch setting.

Before initiating any command the master unit queries for the pres-ence of a “second unit” for a time period of one second. If the mastergets no response the operator will operate in a stand alone mode.NOTE: For single unit applications, a jumper must be placedbetween TB11 and TB12. In this mode no further communicationswill take place during travel. If the master detects the presence of asecond unit the master will continue to query the second unit duringtravel. The second unit will send a response to the master for everyquery. The second operator will stop if there is a period of one sec-ond or more of no communications.

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

ELECTRICAL TROUBLESHOOTING

Symptom Possible Causes SolutionLow or no high voltage power.

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 17 of this manual.

Low or no secondary voltage power.

Measure the voltage at terminals R1 & 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.

No Stop Control 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 TB-3 & TB-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 TB11 and TB12. 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 23.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 plug in loop detectors are working properly and appropriate loops are installed on the loop input terminals P1-P4.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).

No LEDs illuminated on GL board.

If both primary and secondary power is acceptable, check to ensure that the J2 connector is making good contact with the pins on the GL board. If all is good replace GL board.

Transformer's secondary is overloaded.Low primary (high voltage) power.

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 17 of this manual.

Problem in the motor. Perform a visual inspection of the motor. Examine the motor's labels for any distortion or signs of over heating. Replace the motor if it is humming, grinding or making excessive noise. Note: Repeated motor problems indicate poor primary power.

Problem in the contactor. Examine the contactor for sparking, smoke, 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.

Rail slippage 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.

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 17 of this manual.

The contactor chatters when the operator begins to move.

Low primary (high voltage) power.

The operator runs slow and/or trips the internal overload.

Fault in the operator. Check the yellow diagnostic LED at the top right of the GL board next to the programming dip switches.

An accessory is active or malfunctioning. Check the red input status LEDs, D11-D31.

Improper TB11/TB12 wiring (Master/Second).

Operator fails to run.

27

ELECTRICAL TROUBLESHOOTING CONT’D

Symptom Possible Causes SolutionFailure to cycle power after setup. 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.

The communication wiring may be damaged or improperly wired for dual gate operation.

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. Shielded cable should be grounded on one side to chassis ground.

The master or second unit is not programmed correctly.

Review program settings pages 24-25 and check both the master and second for proper programming.

Entrapment (Force Pot) incorrectly set.

This pot must be set so that the gate will run smoothly normally and reverse when encountering an obstruction. See page 23.

Gate is binding or not running smoothly.

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 red LEDs D29 and D31. Both LEDs will indicate the activation of entrapment protection devices on terminals TB-9 and TB-10 on the GL board. Remove the devices and retest. If the operator now runs without fault, check those accessories as well as wiring.

The Hall Effect Sensor is not aligned/adjusted correctly.

Make sure that the sensor is adjusted so that it is centered over the limit shaft's magnet and is 10-15 thousandths of an inch (business card thickness) from the magnet. Replace the sensor if it is adjusted correctly but continues to fail. See page 29.

Rail Slippage 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.

The operator's manual release is engaged.

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 16.

The operator's main power is out of phase (three phase only).

Turn off the unit's main power at the breaker and swap any two power leads at the operator's main power witch. Apply power and retest the operator. See important not on page 18.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 any optional plug in loop detectors are working properly and appropriate loops are installed on the loop input terminals P1-P4.

Operator has trouble learning the motor.

The operator's manual release is engaged.

Make sure that the unit's manual release is not engaged. The unit's manual release, when disengaged, will not allow the entrapment sensor to provide feedback to the GL board when the operator is running. See page 16.

Programming changes do not effect the gate.

Check the save switch on switch S1-1.

If the 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. See page 24.

Gate edge pauses gate when struck during opening.

Open obstruction input is programmed incorrectly.

The open obstruction input has been programmed to function with photo eyes not gate edges. Refer to page 25 and reprogram the obstruction inputs for operation.

Gate does not activate the timer to lose after the close photo eye is broken.

Close obstruction input is programmed incorrectly.

The close obstruction input has been programmed to function with gate edges not photo eyes. Refer to page 25 and reprogram the obstruction inputs to match the accessories that are installed on the operator.

Radio controls will not close the gate from the open limit.

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

Configure terminals R1-4 for single button radio function by performing the modification outlined on page 18.

Check the red input status LEDs, D11-D31, for indication of an active or malfunctioning accessory.

Master or Second operator is not functioning properly.

Operator runs but then stops and reverses direction.

Motor runs but gate doesn't move.

The operator opens immediately upon power up and does not close

HALL EFFECT SENSOR ADJUSTMENT

NOTE: Normally the Hall Effect sensor does not needadjustment, but may go out of alignment due to ship-ping vibration or rough handling.

These operators use an internal entrapment protectorsystem. This system consists of the GL control board,magnet, and Hall Effect sensor. It may become neces-sary to adjust the sensor for correct alignment. To doso please perform the following steps:

1. The sensor must be centered over the magnetwheel. Adjust with vertical screws.

2. The sensor air gap should be adjusted to (.010 -.015 of an inch). (The thickness of a business cardmay be used to gauge the correct distance). Adjustwith horizontal screws.

THINGS TO KNOW ABOUT THE HYDRAULIC SYSTEM

FLUID

1. If and when adding fluid, use ONLY type hydraulicoil (exxon Inivis J13).

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 intothe 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. Ifthe P.S.I. should exceed its factory setting, it will bleedoff the excess. The HS670-100 is set at approx. 600P.S.I. the HS670-200 is set at approx. 1500 P.S.I.

1. Both models have a 4 way, 3 position, dual solenoid activated directional valve. It operates on24 VDC, with a built-in rectifier on each solenoid.Ref. hydraulic circuit on pg. 40.

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. Ref. hydraulic circuit (page 40).

3. Both models have a check valve built into the pump. This valve will not allow fluid to go in the wrong direction. Ref. hydraulic circuit. (page 40)

HYDRAULIC MOTORS

1. The two hydraulic motors are “ROLLER VANE”type and are machined to be free wheeling. Eachmotor has a displacement of 12 in3/ rev.

2. The speed of each is approx. 55 r.p.m. whichequates to a gate speed of approx. 18 inches/persec. for class 3 & 4. For class 1 & 2, the motor’sspeed is 37 RPM and gate speed of 12”/sec.

3. The drive wheels are: HS670 1HP (1 ½” w. x 6” dia.)HS670 2HP (2” w. x 6” dia.). Circumfurance of both: 18.84” Both have a hardness of approx. 70“A” shore.

HOSES - FITTINGS - THREADS

1. All hoses are: S.A.E. 100 R1, type AT, single wirebraid, 3/8” I.D. (Rated working P.S.I.of 2250 and a rated burst P.S.I. of 9000).

2. For information on fittings and threads, see page 43.

HYDRAULIC DON’TS

MUST BE CLEAN,NO PIPE DOPE

ONE WRENCH TOHOLD THIS FITTING

ONE WRENCH TO TIGHTENTHIS FITTING

1. DO NOT use only one wrench to lighten hoseswivel fittings. Use two wrenches, one to tighten andone to hold back opposite fitting. See illustrationabove.

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

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

4. DO NOT remove vent cap except to fill tank withfluid.

5. DO NOT attach hoses to fittings that have dirton them. Clean hoses, fittings and fitting seatscarefully.

WHEN REMOVING HOSES

MANUAL OVERRIDER.H. CLOSE DIRECTION

MANUAL OVERRIDER.H. OPEN DIRECTION

CONTROL PANEL

To minimize loss of fluid when removing hoses, removepower, position bypass valve to manual operation, andpress and hold directional valve manual override for about30 seconds.

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

NOTE: Wear adequate eye protection when perfroming this step.
