⚠️ WARNING: TO REDUCE THE RISK OF SEVERE INJURY OR DEATH:

• READ AND FOLLOW ALL INSTRUCTIONS.
• Never let children operate or play with the gate controls. Keep remote controls away from children.
• Always keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF A MOVING GATE.
• Test the gate operator monthly. The gate MUST reverse on contact with a rigid object or when an object activates a non-contact sensor. If necessary, adjust the force or the limit of travel and then retest the gate operator. Failure to properly adjust and retest the gate operator can increase the risk of injury or death.
• Use the manual release mechanism only when the gate is not moving.
• KEEP GATE PROPERLY MAINTAINED. Have a qualified service person make repairs to gate hardware.
• The entrance is for vehicles only. Pedestrians must use a separate entrance.
• SAVE THESE INSTRUCTIONS.

Important Installation Instructions

Install the gate operator only when the following conditions have been met:

• The operator is appropriate for the type and usage class of the gate.
• All openings of a horizontal slide gate have been guarded or screened from the bottom of the gate to a minimum of 6 feet (1.83 m) above the ground to prevent a 2-1/4 inch (57.2 mm) diameter sphere from passing through openings anywhere in the gate or through that portion of the adjacent fence that the gate covers when in the open position.
• All exposed pinch points are eliminated or guarded.
• Guarding is supplied for exposed rollers.

The operator is intended for installation on gates used by vehicles only. Pedestrians must be provided with a separate access opening.

To reduce the risk of entrapment when opening and closing, the gate must be installed in a location that allows adequate clearance between the gate and adjacent structures. Swinging gates shall not open outward into public access areas.

Before installing the gate operator, ensure that the gate has been properly installed and that it swings freely in both directions. Do not over-tighten the operator clutch or pressure relief valve to compensate for a damaged gate.

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. Exception: Emergency access controls only accessible by authorized personnel (e.g. fire, police, EMS) may be placed at any location in the line-of-sight of the gate.

The Stop and/or Reset buttons must be located within line-of-sight of the gate. Activation of the reset control shall not cause the operator to start.

All warning signs and placards must be installed and easily seen within visible proximity of the gate. A minimum of one warning sign shall be installed on each side of the gate.

For gate operators that utilize a non-contact sensor (photo beam or the like):

• See instructions on the placement of non-contact sensors for each type of application.
• Exercise care to reduce the risk of nuisance tripping, such as when a vehicle trips the sensor while the gate is still moving.
• Locate one or more non-contact sensors where the risk of entrapment or obstruction exists, such as at the reachable perimeter of a moving gate or barrier.

For gate operators that utilize a contact sensor (edge sensor or similar):

• 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 postmounted both inside and outside of a vehicular horizontal slide gate.
• One or more contact sensors shall be located at the bottom edge of a vehicular vertical lift gate.
• One or more contact sensors shall be located at the pinch point of a vehicular vertical pivot gate.
• A hardwired contact sensor shall be located and its wiring arranged so that the communication between the sensor and the gate operator is not subjected to mechanical damage.
• A wireless device such as 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 device shall function under the intended end-use conditions.
• 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 152 mm (6 in) but less than 406 mm (16 in) above the ground at any point in its arc of travel, one or more contact sensors shall be located on the bottom edge.
• One or more contact sensors shall be located at the bottom edge of a vertical barrier (arm).

1. DESCRIPTION & SPECIFICATIONS

844 OPERATOR

The FAAC Model 844 is an electro-mechanical operator for sliding gates transmitting motion to the sliding leaf via a rack or chain pinion appropriately coupled to the gate. The non-reversing system ensures the gate is mechanically locked when the motor is not operating and, therefore, no lock needs to be installed. The gearmotor is equipped with a mechanical clutch which, combined with an electronic device, offers the necessary adjustable anti-crushing safety and guarantees stopping or reversing the gate movement. A handy manual release makes it possible to move the gate in the event of a power cut or malfunction. The control board, if supplied with the gearmotor, it is placed inside the operator. The 844 automated system is designed and manufactured to control access of vehicles. Do not use for any other purpose.

Adjustment Screw for Anti-crushing Clutch, 7. Oil Filling Plug, 8. Operator Grounding System, 9. Lever Operated Release, 10. Protective Side Panels, 11. Cover for 780D Control Board.

1.1. Maximum Use Curve

The curve makes it possible to establish maximum work time (T) according to use frequency (F). The 844 gearmotor can operate non-stop at 70% use frequency. To ensure efficient operation, operate in the work range below the curve. Important: The curve is obtained at a temperature of 75°F. Exposure to direct sunlight can reduce use frequency down to 20%.

Calculating Use Frequency

The percentage of effective work time (opening + closing) compared to total time of cycle (opening + closing + pause times). Calculation formula: %F = (Ta + Tc) / (Ta + Tc + Tp + Ti) X 100, where: Ta = opening time, Tc = closing time, Tp = pause time, Ti = time of interval between two complete cycles.

4. INSTALLATION

4.1. Preliminary Checks

To ensure safety and an efficiently operating automated system, make sure the following conditions are observed:

• The gate structure must be suitable for automation. For example, wheel diameter must be in proportion to the weight of the gate to be automated, an upper guide must be provided, mechanical stop limits to prevent the gate derailing must be installed.
• The soil must permit sufficient stability for the concrete pad.
• There must be no pipes or electric cables in the pad excavation area.
• If the operator is exposed to passing vehicles, install, if possible, adequate means of protection against accidental impact.
• Check if an efficient grounding is available for connection to the gearmotor.

4.2. Foundation Plate Installation

1. Assemble the foundation plate as shown in Fig 4. The foundation plate must be located as shown in Fig 5 (right closing) or Fig 6 (left closing) to ensure that the rack and pinion mesh correctly.
2. Prepare a concrete pad as shown in Fig. 7, following the suggested dimensions. It's recommended to have the pad a minimum of 4" above level grade to avoid any flooding of the operator. The underground depth of the concrete pad is determined by the soil condition and the local building codes. Make sure the concrete pad is leveled.
3. Provide one or more conduit pathways for all power and accessory connections. Extend the conduit about 1/2" above the level of the concrete pad.
4. After the concrete is poured in the forms and before it has a chance to set, insert the foundation plate into the cement and position it flush with the top of the concrete and aligned with the top of the lower gate frame. Use the dimensions shown in Figs 5 or 6 to align your foundation plate. Allow the concrete to set for a minimum of two days before installing the operator.
5. Route the wires in the conduits. To facilitate the connections allow for about 15" of extra length of cables out of the conduit. Separate the high and low voltage wires in different conduits.

Diagrams (Fig. 7, 11) show dimensions and alignment for foundation plate installation.

4.3. Mechanical Installation

1. Assemble the mounting brackets and anti-vibration spacers on the operator as shown in Fig. 8.
2. Open the cover, remove the securing screws.
3. Attach the operator to the plate, using the supplied washers and nuts as shown in Fig. 9. Route cables through the opening inside the lower half-casing of the operator (Fig. 10 - Ref. A).
4. Adjust the height and distance from the gate as shown in Fig 11.
5. Secure the operator to the foundation plate, tighten nuts as shown in Fig. 12.

2. Manually move the leaf to its closed position.
3. Lay the first piece of rack level on the pinion and weld the threaded dowel nut to the gate (Fig. 15).
4. Move the gate manually, checking that the rack is resting on the pinion, then weld the second and third dowel nut.
5. Place another rack element next to the previous one, use a third piece of rack (Fig. 16) to synchronize the teeth of the first two elements.
6. Move the gate manually and weld the three threaded dowel nuts. Proceed as described until the gate is fully covered.

4.4.2. STEEL RACK TO SCREW (Fig. 14)

1. Manually move the leaf to its closing position.
2. Lay the first piece of rack level on the pinion and place the spacer between the rack and the gate, positioning it at the top of the slot.
3. Mark the drilling point on the gate. Drill a Ø 1/4 inch hole and apply thread with a Ø 5/16 inch male tap. Screw in the bolt.
4. Move the gate manually, checking that the rack is resting on the pinion. Repeat step 3.

Notes on Rack Installation

• Make sure that, during gate travel, no rack elements derail from the pinion.
• Do not, for any reason, weld the rack elements either to the spacers or to each other.
• When the rack has been installed, to ensure that it meshes correctly with the pinion, lower the gearmotor position by about 1/16 inch (Fig. 17).
• Manually check that the gate regularly reaches the mechanical stop limits and make sure there is no friction during gate travel.
• Do not use grease or other lubricants between rack and pinion.

4.5. INSTALLATION OF CHAIN PINIONS

The operators for chain and idle transmissions require the installation of a Z16 or Z20 chain pinion.

4.5.1. MODEL 844 ER CAT (Figs. 18 & 19)

Opening Safety Devices:

Active only during gate opening movement. When an obstacle is detected they cause immediate reversing and resumption of the opening motion on release (see advanced programming in Section 5.5.2.)

Closing Safety Devices:

Active only during gate closing movement. When an obstacle is detected they cause reversing, either immediate or on release (see advanced programming in Section 5.5.2.)

Edge Safety Devices:

Active during the gate opening and closing movements. They cause immediate reversal of motion and stopping after two seconds.

Encoder:

Monitors for an obstacle during gate opening and closing movements. It causes immediate reversal of motion and stopping after two seconds.

Note: For compliance with UL325 all safety devices that protect entrapment zones must be monitored. The 844 operator monitors the safety devices with the FAIL SAFE function. See advanced programming in Section 5.5.2 for details on the different options for Fail Safe.

A minimum of one external device for each direction of travel must be connected and monitored. See the following figures for various examples of connections.

6. START-UP

6.1. ELECTRIC CONNECTIONS

Make all electrical connections to the board as described in Section 5, including grounding the operator (Fig. 34).

6.2. OPENING - CLOSING DIRECTIONS

Power up the system and set the opening direction on the board (see Section 5.5.1).

If opening direction is to the RIGHT (3): OPENING limit-switch LED = FC1, CLOSING limit-switch LED = FC2.

If opening direction is to the LEFT (E): OPENING limit-switch LED = FC2, CLOSING limit-switch LED = FC1.

Note: for RF chain applications the wires on Mot1 and Mot2 (See Fig. 23) need to be reversed.

6.3. DETERMINING STOP POINTS AT TRAVEL LIMIT

The 844 operator has a limit sensor switch which, by detecting the transit of a reference applied to the rack, commands the motor to stop. The device can be magnetic (Fig. 41) or inductive (Fig. 42).

6.3.1. Magnetic Limit-Switch (MLS)

The MLS limit-switch detects the transit of two magnets fitted on the side of the rack facing the operator. Procedure for correct positioning of the two supplied magnets:

1. Check that the operator is in manual mode (see Sec. 8).
2. Manually open the gate to within 3/4 to 2 inches of the travel limit mechanical stop.
3. Fit the magnet on the rack as shown in the instruction sheet that comes with the magnets. Slide the magnet on the rack in opening direction until the relevant LED turns off (Fig. 22 and 41), then move the magnet forward an additional 1 3/4 inches.
4. Manually close the gate to within 3/4 to 2 inches of the travel limit mechanical stop.
5. Fit the magnet on the rack as shown in the instruction sheet that comes with the magnets. Slide the magnet on the rack in closing direction until the relevant LED turns off (Fig. 22 and 41), then move the magnet forward an additional 1 3/4 inches.
6. Move the gate to its halfway travel point and relock the system (see Sec. 9).
7. Find out the desired pre- and post-limit-switch deceleration values (see Section 5.5.2) and run the automated system for at least one complete cycle.
8. Check that the gate stops approximately 3/4 to 2 inches from its mechanical stop point. If necessary, correct the position of the magnets and check that the stop point is correct.
9. Tighten the magnets in holders at desired stop points.

Attention: Due to the powerful magnetic fields produced by the supplied magnets, do not place magnetic storage devices (credit cards, magnetic tapes, floppy disks, etc) or sensitive electronic equipment (watches, CRT monitors, LCD screens, etc.) near the magnets.

Notes on Magnet Positioning

• To ensure correct operation, allow at least 3/4 inch from the mechanical stop limit in the gate stop position. Carry out this check after determining the values of the pre- and post-limit switch decelerations (see Section 5.5.2.) and after running at least one complete cycle of the automated system.
• The distance between the limit-switch and magnets must be from 1/4 to 1/2 inch.

6.3.2. Inductive Limit-Switch

The inductive limit-switch detects the travel of the two steel plates fitted on the top of the rack or the chain. Procedure for correct positioning of the two supplied steel plates:

1. Assemble the limit-switch by centering the plate with respect to the threaded pins of the support (Fig. 36).
2. Check that the operator is in manual operating mode (see Section 8).
3. Manually open the gate to within 3/4 to 2 inches of the mechanical stop limit.
4. Allow the plate to move on the rack in opening direction until the relevant LED goes off (Figs. 22 and 36); next, move the plate forward an additional 1 3/4 inches and secure it to the rack by tightening the screws.
5. Manually close the gate to within 3/4 to 2 inches of the mechanical stop limit.
6. Allow the plate to move on the rack in closing direction until the relevant LED goes off (Figs. 22 and 36); next, move the plate forward by an additional 1 3/4 inches and secure it to the rack by tightening the screws.

Notes on Plate Positioning

• To ensure correct operation, allow at least 3/4 inch from the mechanical stop limit in the gate stop position. Carry out this check after determining the values of the pre- and post-limit switch decelerations (see Section 5.5.2.) and after running at least one complete cycle of the automated system.
• The distance between the limit-switch and the plates must be ≤ 3/16 inch.

6.4. INPUTS CHECK

The table below shows the status of the LEDs in relation to the status of the inputs. Note the following:

• LED ON = closed contact
• LED OFF = open contact

Check the status of the LEDs as per the following table. Note: The status of the LEDs while the gate is closed are shown in bold. If opening direction is to the left, the status of LEDS FC1 and FC2 is reversed.

Table 2: Operation of the Signalling Status LEDs

6.5. MECHANICAL CLUTCH ADJUSTMENT

In addition to its electronic safety devices (encoder and force adjustment), the 844 operator is also equipped with a mechanical clutch. The clutch doesn't need to be adjusted in a typical application. To adjust the operator's thrust and reversing behavior use the force and encoder settings, as detailed in Sections 5.5.1 and 5.5.2.

1. Adjust the F0 setting in Basic Programming so the gate pushes hard enough but not too hard.
2. Adjust the EC setting in Advanced Programming so the gate reverses when it hits a rigid object/obstruction.

For more information on how to adjust the combination of clutch, force and encoder see section 10.

In case the clutch needs to be adjusted:

1. Cut electrical power to the operator.
2. Keep the motor shaft locked with a wrench and turn the clutch adjustment screw with an Allen wrench or screwdriver as shown in Fig. 37 Ref. A.
• To increase torque, turn the screw clockwise.
• To reduce torque, turn the screw counter-clockwise.
3. Power up the operator and check that the torque you have just set is correct.

The operator is supplied as standard with a clutch adjustment spring for gates up to 2200 lbs. For heavier gates, use the supplied alternative spring. For spring replacement instructions, see Fig. 37 Ref. B.

6.6. TRAVEL LIMITS CHECK

Be careful when setting the post-limit-switch deceleration and braking. If the deceleration is too long and braking is insufficient, the magnet or steel plate fitted on the gate's rack can overshoot the sensor until it is disengaged.

When the gate stops, check that the correct limit-switch light is engaged. The relevant LED must be OFF. If it went OFF and then ON again, or if both limit-switch LEDS are OFF, you must reduce the post-limit-switch deceleration value and/or increase the braking value (see Section 5.5.2).

6.7. SAFETY DEVICES CHECK

Check for the correct operation of all safety equipment, anti-crushing devices (ENCODER sensor), and accessories used in the system.

7. FINAL OPERATIONS

• After installation, apply the danger sticker to the top of the cover (Fig. 38).
• Snap-fit the side panels, put the equipment's cover on and secure it with the supplied screws (Fig. 39).
• Remove the vent screw (Fig. 40).

8. MANUAL OPERATION

If the gate has to be operated manually due to a power outage or malfunction of the automated system, use the release device as follows:

1. Open the protection door and insert the supplied key in the lock (Fig. 41).
2. Turn the key clockwise and pull the release lever as shown in Fig. 42.
3. Open and close the gate manually.

9. RESTORING NORMAL OPERATION

To prevent an involuntary pulse from activating the gate, cut power to the system before re-locking the operator.

1. Re-close the release lever.
2. Turn the key counter-clockwise.
3. Remove the key and close the lock protection door.
4. Move the gate until the release engages.

10. FORCE ADJUSTMENT

Make sure the gate travels smoothly in both directions before starting the adjustment. Obstruct the gate then adjust the F0 setting appropriately so the gate does not slip the clutch during normal operation but does upon hitting an object. If the clutch keeps slipping tighten it as described in Section 6.5.

By lowering the F0 setting from 50 (maximum) the operator limits how hard the gate is pushed, which in turn will allow the clutch to slip. Once the force is set appropriately move on to the encoder adjustment.

The Encoder has multiple purposes but the adjustment here is just for obstacle detection. 01 is the most sensitive (reverses more easily) and 99 is the least sensitive. The machine comes set at 99 so in most instances after, and sometimes during the Force adjustment you will bring the setting down from 99 to a lower number so the machine will reverse on obstructions.

If it is too sensitive the gate will reverse during normal travel with no obstructions. If this happens twice the display will show 09 which requires a reset to continue operation.

The goal is to have a combination of Force and Encoder settings so that the gate travels fine during normal operation but the clutch slips and then the Encoder senses the obstruction when the gate contacts a rigid obstacle.

11. MAINTENANCE

Check the operational efficiency of the system at least once every 12 months, especially the efficiency of the safety and release devices (including operator thrust force).

• Check that the operator is intact and securely fastened.
• Check that the pinion doesn't have any flat spots on the shaft.
• Check that the hand guard around the pinion is present and intact.
• Check that the operator can't be pushed in reverse.
• Check that there are no oil leaks.
• Check the condition of the cables, cable glands and junction boxes.
• Check that the connectors and wiring are solid.
• Check that there are no signs of overheating, burning etc. of electronic components.
• Check that the ground connection is intact.
• Check that the limit switches are in place and operating correctly.

11.1. REMOVING BOARD AND TRANSFORMER

If you have to disassemble the transformer-board unit, proceed as follows:

1. Remove all terminal boards and connectors from the board.
2. Unscrew the 3 screws from the board and the 2 from the transformer. Lift the unit up and gently remove the transformer from the couplings on the board as shown in Fig. 43.

11.2. REPAIRS

For any repairs, contact an FAAC authorized repair center.

12. LOGICS TABLES

Detailed logic tables (Tab. 3/a through Tab. 3/h) describe the behavior of the gate operator under various input conditions (pulses, safety devices) for different logic modes (A, AP, S, E, EP, C, B, B/C). These tables specify how the gate status changes based on inputs like OPEN-A, OPEN-B, STOP, Opening Safety Devices, Closing Safety Devices, OP/CL Safety Device, and Edge Safety Device.

Key notes for tables:

• (1) If maintained, it prolongs the pause until disabled by the command (timer function).
• (2) If a new pulse occurs within 2 seconds after reversing, it immediately stops operation.
• (3) During the partial opening cycle, an OPEN A pulse causes total opening.
• NB.: Effects on other active pulse inputs in brackets.

FAAC International, Inc., warrants, for twenty-four (24) months from the date of invoice, the gate operator systems and other related systems and equipment manufactured by FAAC S.p.A. and distributed by FAAC International, Inc., to be free from defects in material and workmanship under normal use and service for which it was intended provided it has been properly installed and operated.

FAAC International, Inc.'s obligations under this warranty shall be limited to the repair or exchange of any part of parts manufactured by FAAC S.p.A. and distributed by FAAC International, Inc. Defective products must be returned to FAAC International, Inc., freight prepaid by purchaser, within the warranty period. Items returned will be repaired or replaced, at FAAC International, Inc.'s option, upon an examination of the product by FAAC International, Inc., which discloses, to the satisfaction of FAAC International, Inc., that the item is defective. FAAC International, Inc. will return the warranted item freight prepaid. The products manufactured by FAAC S.p.A. and distributed by FAAC International, Inc., are not warranted to meet the specific requirements, if any, of safety codes of any particular state, municipality, or other jurisdiction, and neither FAAC S.p.A. or FAAC International, Inc., assume any risk or liability whatsoever resulting from the use thereof, whether used singly or in combination with other machines or apparatus.

Any products and parts not manufactured by FAAC S.p.A. and distributed by FAAC International, Inc., will carry only the warranty, if any, of the manufacturer. This warranty shall not apply to any products or parts thereof which have been repaired or altered, without FAAC International, Inc.'s written consent, outside of FAAC International, Inc.'s workshop, or altered in any way so as, in the judgment of FAAC International, Inc., to affect adversely the stability or reliability of the product(s) or has been subject to misuse, negligence, or accident, or has not been operated in accordance with FAAC International, Inc.'s or FAAC S.p.A.'s instructions or has been operated under conditions more severe than, or otherwise exceeding, those set forth in the specifications for such product(s). Neither FAAC S.p.A. nor FAAC International, Inc., shall be liable for any loss or damage whatsoever resulting, directly or indirectly, from the use or loss of use of the product(s). Without limiting the foregoing, this exclusion from liability embraces a purchaser's expenses for downtime or for making up downtime, damages for which the purchaser may be liable to other persons, damages to property, and injury to or death of any persons.

FAAC S.p.A. or FAAC International, Inc., neither assumes nor authorizes any person to assume for them any other liability in connection with the sale or use of the products of FAAC S.p.A. or FAAC International, Inc. The warranty herein above set forth shall not be deemed to cover maintenance parts, including, but not limited to, hydraulic oil, filters, or the like. No agreement to replace or repair shall constitute an admission by FAAC S.p.A. or FAAC International, Inc., of any legal responsibility to effect such replacement, to make such repair, or otherwise. This limited warranty extends only to wholesale customers who buy directly through FAAC International, Inc.'s normal distribution channels. FAAC International, Inc., does not warrant its products to end consumers.

Consumers must inquire from their selling dealer as to the nature and extent of that dealer's warranty, if any. This warranty is expressly in lieu of all other warranties expressed or implied including the warranties of merchantability and fitness for use. This warranty shall not apply to products or any part thereof which have been subject to accident, negligence, alteration, abuse, or misuse or if damage was due to improper installation or use of improper power source, or if damage was caused by fire, flood, lightning, electrical power surge, explosion, wind storm, hail, aircraft or vehicles, vandalism, riot or civil commotion, or acts of God.
