Important Safety Information
Both the installer and the owner and/or operator of this system need to read and understand this installation manual and the safety instructions supplied with other components of the gate system.
This information should be retained by the owner and/or operator of the gate.
WARNING! To reduce the risk of injury or death
1. READ AND FOLLOW ALL
INSTRUCTIONS.
2. Never let children operate or play with gate controls. Keep the remote control away from children.
3. Always keep people and objects away from the gate. NO ONE SHOULD
CROSS THE PATH OF THE
MOVING GATE.
4. Test the gate operator monthly. The gate MUST reverse on contact with a rigid object or stop when an object activates the non-contact sensors. After adjusting the force or the limit of travel, retest the gate operator. Failure to adjust and retest the gate operator properly can increase the risk of injury or death.
5. Use the emergency release only when the gate is not moving.
6. KEEP GATES PROPERLY
MAINTAINED. Read the owner’s manual. Have a qualified service person make repairs to gate hardware.
7. The entrance is for vehicles only.
Pedestrians must use separate entrance.
8. SAVE THESE INSTRUCTIONS.
There are three kinds of safety issues involved with an automatic gate operator: issues arising from the design of the gate, from the installation of the gate and the operator, and from the use of the gate operator. The following information is designed to help you be sure your gate and its operator are well-designed, installed correctly, and used safely.
Gate Design
1. A gate is a potential traffic hazard, so it is important that you locate the gate far enough away from the road to eliminate the potential of traffic getting backed up. This distance is affected by the size of the gate, how often it is used, and how fast the gate operates.
2. The operator you choose to install on your gate must be designed for the type and size of your gate and for the frequency with which you use the operator.
3. Your gate must be properly installed and must work freely in both directions before the automatic operator is installed.
4. An automatic operator should be installed on the inside of the property/fence line. Do not install the operator on the public side of the property/fence line.
5. Pedestrians should not use a vehicular gate system.
Prevent such inappropriate use by installing separate gates for pedestrians.
6. Exposed, reachable pinch points on a gate are potentially hazardous and must be eliminated or guarded.
7. Outward swinging gates with automatic operators should not open into a public area.
8. The operating controls for an automatic gate must be secured to prevent the unauthorized use of those controls.
9. The controls for an automatic gate should be located far enough from the gate so that a user cannot accidentally touch the gate when operating the controls.
10. An automatic gate operator should not be installed on a gate if people can reach or extend their arms or legs through the gate. Such gates should be guarded or screened to prevent such access.
Installation
1. If you have any question about the safety of the gate operating system, do not install this operator.
Consult the operator manufacturer.
2. The condition of the gate structure itself directly affects the reliability and safety of the gate operator.
3. Only qualified personnel should install this equipment. Failure to meet this requirement could
2
Use
cause severe injury and/or death, for which the manufacturer cannot be held responsible.
4. The installer must provide a main power switch that meets all applicable safety regulations.
5. Clearly indicate on the gate with a minimum of 2 warning signs (visible from either side of the gate) that indicate the following:
•
The gate is automatic and could move at any time, posing a serious risk of entrapment.
•
Children should not be allowed to operate the gate or play in the gate area.
•
The gate should be operated only when it is visible to the operator and the when the area is free of people and obstructions.
6. It is extremely unsafe to compensate for a damaged gate by overtightening a clutch or increasing hydraulic pressure.
7. Devices such as reversing edges and photocells must be installed to provide better protection for personal property and pedestrians. Install reversing devices that are appropriate to the gate design and gate application.
8. Before applying electrical power, be sure that the voltage requirements of the equipment correspond to your supply voltage. Refer to the label on your operator system.
1. Use this equipment only in the capacity for which it was designed. Any use other than that stated should be considered improper and therefore dangerous.
2. When using any electrical equipment, observe some fundamental rules:
•
Do not touch the equipment with damp or humid hands or feet.
•
Do not install or operate the equipment with bare feet.
•
Do not allow small children or incapable persons to use the equipment.
3. If a gate system component malfunctions, turn off the main power before making any attempt to repair it.
4. Do not attempt to impede the movement of the gate. You may injure yourself as a result.
5. This equipment may reach high temperatures during operation; therefore, use caution when touching the external housing of the operator.
6. Learn to use the manual release mechanism according to the procedures found in this installation manual.
7. Before carrying out any cleaning or maintenance operations, disconnect the equipment from the electrical supply.
8. To guarantee the efficiency of this equipment, the manufacturer recommends that qualified personnel periodically check and maintain the equipment.

The Control Panel
The 750 Operator must be installed with a 450 MPS control panel to be a U.L. recognized installation. The
450 MPS can be used to control a single 400 operator or a dual (biparting) system. Both the control panel and the operator must use the same power supply voltage.
The 450 MPS
To determine the voltage requirement of your 450 MPS control panel, refer to the label on the transformer of the control panel:
Label reads: 450MPSUS = 220 VAC
450MPSUS115 = 115 VAC
Operating logics available: E, EP, A, S, B, and C
Unpacking the Operator
When you receive your 750 Operator, complete the following steps.
Inspect the shipping box for physical damage such as leaking oil or a torn carton. Then inspect the operator after you remove it from the box. Notify the carrier immediately if you note any damage because the carrier must witness the damage before you can file a claim.
As you unpack the boxes, insure that all the parts listed below are included.

The 750 Operator
General Characteristics
The FAAC 750 Operator is an automatic gate operator for a swinging gate leaf. It can accommodate a gate leaf of up to 1760 lb (800 kg) and up to 13 ft (4 m) in length.
The 750 Operator is a two piece unit consisting of a hydraulic power (or pump) unit and a hydraulic ram (or drive) unit which are connected by the means of two hydraulic hoses.
The 400 Operator can be used to swing the gate leaf inward or outward. Some versions provide hydraulic locking in at least one position, either opened or closed, depending on how it was ordered.
The hydraulic lock is a service device rather than a security device. Additional, external locks are recommended under the following conditions:
The two bypass valves are located on the front of the pump unit. You need to adjust the bypass valves to meet the safety standards of FAAC International, Inc. The standards state that the gate leaf should stop if it encounters a force of more than 33 lb (15 kg).
Additional reversing devices (such as inductive loops and photocells) should be installed to provide more complete protection for people and property.
The electronic control panel is a microprocessor-based controller that accepts a wide range of product accessories and reversing devices, thus allowing for flexible gate system design.
450 MPS Logic Modes
Note: The 450 provides inputs for opening reversing devices and closing reversing devices. FAAC strongly recommends the use of reversing devices, such as photocells or other non-contact sensors.
•
You are installing the Model 750 SB or SBS.
•
The length of the gate leaf is 7 ft or more.
•
The installation requires tight security.
•
The site is subject to vandalism.
•
The site is subject to strong or very gusty wind.
•
You are installing a solid face gate.
For gates with two leaves, two operators are installed, one on each leaf, and both are wired to one control panel. In such two-operator gate installations, one leaf can be programmed to open/ close slightly later than the other leaf to accommodate overlapping gate designs.
For its protection, the single-phase, bidirectional motor shuts off automatically if its operating temperature reaches 212 deg F (100 deg C). Also for the protection and proper operation of the 750 Operator, each gate leaf on which it is installed must have a fixed positive stop in both the opened and closed positions.
The 750 Operator also includes a key-operated Manual
Release mechanism and two bypass valves that precisely control the force applied to the gate leaf through the 750 Operator.
The Manual Release mechanism is a lever that disengages (or engages) the hydraulic system of the 750
Operator. When the hydraulic system is disengaged, you can open and close the gate leaf by hand. Such manual operation of the gate is necessary during installation and useful during power failures.
The following logics are available on the 450 MPS:
•
A (automatic): The gate opens on command and automatically closes after a pause phase. A second command on opening is ignored; a second command during the pause phase causes the gate to close immediately; a second command during closing reopens the gate.
•
S (security): The security mode is like A logic except that a second command during opening immediately closes the gate.
•
E (semi-automatic): This mode requires a command to open and a command to close. A second command during opening or closing causes the gate leaves to stop. A third command then closes the gate.
•
EP (semi-automatic, step by step): This mode requires a command to open and a command to close. A second command during opening or closing causes the gate leaves to stop. A third command then reverses the previous motion of the gate.
•
B (manned, pulsed): This mode is designed for guard station use and requires a threebutton switch (pulsed) to open, close, and stop the gate.
•
C (manned and constant): This mode requires constant pressure switches. One to open and one to close. No pressure on a switch stops the gate.

Installation Instructions
Note: The following installation instructions assume you are fully capable of installing a gate operator. This manual does not instruct you in designing a gate, installing a gate, or basic electrical wiring. The installation tasks discussed in this manual are tasks particular to the 750 Operator.
Preparing the Gate
Before you install the 750 Operator, you must insure that the gate leaf meets the following criteria.
1. The gate leaf must not exceed the weight and length constraints for 750 Operator that you have.
2. The distance between the gate post and the center of the gate hinge must be at least 2 3 /
8
in.
(6 cm).
3. Make sure the gate leaf has positive stops in both the opening and closing directions (see Figure 3).
Note: If you are installing the 750 Operator with an extension arm, some of the constraints about the gate leaf may not apply to you. See the section "Installing an Extension Arm" for more information on page 26.
Installing the 750 Operator
Installing the 750 Operator consists of the following steps:
Setting the concrete forms
Installing the power unit
Installing the drive unit
Connecting the hydraulic lines
Synchronizing the hydraulic system
Installing the gate leaf shoe
Installing the gate leaf
Installing the control panel
Adjusting the hydraulic pressures for the operator
Checking the motor rotation
Bleeding the hydraulic system
Adjusting the bypass valves
Set the Concrete Forms
You need to lay out the concrete forms according to the dimensions shown in Figures 4 and 5. (Your soil conditions may also determine the size of the cement footing.)
Note: If the vertical distance between the finished grade and the bottom of the gate leaf exceeds 1 1/4 in. (3.3 cm) as shown in Figure 5, you can install a shear-pin assembly as shown in Figure 9 and as discussed in
“Installing the Gate Leaf Shoe.”

Figure 2. Constraints on the geometry of the gate leaf
Accurately positioning the foundation plate beneath the gate hinge is critical especially if it supports the drive unit, which supports the gate leaf.
Note: The foundation plate may be supplied by the installer. If so, it must meet the specifications shown in Figure 4.
Cement footing
Note: Insure that the cavity where the drive unit is located is well drained by means of pipes, gravel drainage, or both, whatever is appropriate for your soil conditions.

There are two constraints to installing the power unit box for the 750 Operator. m).
Figure 5. Recommended dimensions for the concrete footing and foundation plate, side view
After the concrete is poured in the form and before it has a chance to set, insert the foundation plate into the cement and position it so that it is flush with the top of the concrete and is level.
Allow the concrete to set a minimum of two full days before you install the drive unit on top of it.
1. We recommend that you install the power unit box so that the hydraulic lines between it and the drive unit are no longer than 20 ft (6
2. The power unit itself must be installed so that the vent screw in on the top of the unit as shown in Figure 6.
The power unit box that ships with your operator hinges on the left, but you can reverse the opening direction of the door if necessary for your installation. To reverse the opening direction, open the cover, and then lift it off the box. The vinyl hinges can now be placed in the hinge receptacles on the right-hand side. Secure the hinges with the screws provided.
You may surface mount the power unit box to a vertical surface or you may recess it.
To mount the power unit box use the 3/16-in. holes provided (relocating the holes in the box will compromise its integrity).
If you recess the box, keep in mind that hydraulic hoses and electrical wiring need to enter the bottom of the box.
Also, recesseing must not interfere with the hinge assembly of the power unit box. You need to keep in mind the following dimensions.
Height: 14 1/4 in. (36.2 cm)
Width: 10 in. (25.5 cm)
Depth: maximum of 2

At this time, you also need to remove the vent screw located on the power unit. The vent screw is in the middle of the top, left side of the power unit as shown in Figure 6.
Caution: Failure to remove the vent screw in the power unit may result in erratic operation of the 750 Operator.

Install the Drive Unit
To install the drive unit, first make sure the four leveling bolts on the base of the unit do not protrude from the bottom of the unit. Then place the unit on the foundation plate (see Figure 7).
Position the drive unit according to the following:
1. The side of the drive unit with the splined shaft should be the side nearest the gate post.
2. The longitudinal axis of the drive unit is perpendicular to (at right angles to) the fully closed gate leaf.
3. The center of the splined shaft is vertically aligned with the center of the gate hinge axis
(use a plumb line).
Caution: NEVER weld the base plate of the drive unit to the foundation plate. Weld only the mounting C brackets to the foundation plate.
When the position of the drive unit meets these conditions, weld the C-shaped mounting brackets to the foundation plate to hold the drive unit in position
(see Figure 7).
Splined shaft: This side of the drive unit should be nearest the gate post.

Next you need to prepare the two L-shaped "box halves" for installation. Note that the lip on each piece should be on top so as to support the top cover. Make the necessary holes for the two hydraulic lines that run from the drive unit to the power unit.
Once you have made your access holes, you can weld the box halves to the foundation plate and to one another so as to enclose the drive unit on four sides. Be sure to protect the drive unit during welding.
Connect the Hydraulic Lines
Caution: It is important that the hydraulic lines be kept clean of any debris.
The drive unit and power unit are connected by two hydraulic lines, each with an outside diameter of 5/16 in. (0.8 cm), an inside diameter of 5/32 in. (0.4 cm), and a 2,500 psi (170 bar) rating.
Caution: After removing the nylon piping, do not rotate the splined shaft while you are connecting the hydraulic lines to avoid squirting hydraulic fluid.
Remove the nylon piping connecting the two hydraulic pipe fittings on the drive unit. Clean up any spilled hydraulic fluid.
Be sure the hydraulic lines are free of any debris by flushing them with a jet of compressed air. Then attach one line to each fitting on the drive unit.
Next you attach the other end of the hydraulic lines to the pipe fittings on the power unit (see Figure 8; additional information can be found in the technical drawing on page 29). Attaching the correct line to the correct fitting is important. Make sure that the hose on the end of the drive unit that is on the closing side of the gate/fence line attaches to the hydraulic pipe fitting in the power unit that is nearest the green bypass valve
screw. This connection insures that the green valve controls opening pressure.
Caution: Do not remove and do not tighten the elbow-shaped pipe fittings on the power unit.
They have been locked into position with a thread locker to help seal the hydraulic system.
Synchronize the
Hydraulic System
Next you need to disengage the hydraulic system in order to synchronize it.
Inside the power unit is the Manual Release lever that disengages the hydraulic system (see Figure 1). Make
•
Install a length of appropriately sized pipe between the sleeve that fits around the splined shaft of the operator and the gate leaf shoe.
•
Construct a shear-pin assembly to accommodate the extra vertical distance. The assembly is welded to the bottom of the gate leaf shoe on one end and to the sleeve for the splined shaft of the pinion on the other end
(see Figures 9 and 10). Such an assembly requires a bottom hinge and also protects the pinion and splined shaft in the event something hits the gate with great force.
Axis of rotation of the gate leaf
Weld this end of this pipe to the bottom of the gate leaf shoe, being certain you have aligned the axes of rotation.
This 2 in. pipe (schedule 160) has an inside diameter of 1.689 in.
Figure 8. Connect the hydraulic line to the power unit. See the technical drawing on the next to last page for more information.
sure the Manual Release lever is turned toward you and down to disengage the hydraulic system.
Now you can synchronize (set) the hydraulic system to the closed position by turning the splined shaft in the closing direction. Turn the shaft as far as it will go. To prevent the piston in the drive unit from bottoming in its cylinder, next turn the splined shaft about 5 deg in the opening direction.
The position of the shaft now corresponds to the fully closed position of the gate leaf. The hydraulic system is now synchronized (set).
Caution: The splined shaft must not be moved from its closed position until the gate leaf shoe that holds the gate leaf has been attached.
Install the Gate Leaf Shoe
If the vertical distance between the finished grade under the gate and the bottom of the gate leaf is more than
1 1/4 in. (see Figure 5), you need to do one of the following:
13
Bolt or shear pin goes through these holes and the holes on the opposite sides of the pipes.
Weld this end of this pipe to the
sleeve for the splined shaft (do not weld anything to the splined shaft itself). This 1 1/4 in. pipe (schedule
160) has an outside diameter of
1.660 in.
Figure 9. A sample shear-pin assembly
Installing the gate leaf shoe involves making the gate leaf shoe, positioning it, and welding it to the splined shaft sleeve. If you are retrofitting the 750 Operator to an existing gate, these tasks require you to remove the gate leaf from its hinges. If you are using a shear-pin assembly, refer to Figures 9 and 10 to determine what you should weld together.
The gate leaf shoe is designed to carry the weight of the gate leaf and transfer the weight to the splined shaft.
The shoe surrounds the 90-deg gate-post corner of the gate leaf to carry the gate and to act as a lower hinge.
The shoe is made of a U-shaped section and a vertical section (see Figure 10). Later you will weld the bottom of the U-shaped section to the sleeve for the splined shaft (or to the shear-pin assembly, which is welded to the sleeve).
Since the gate leaf shoe holds the gate leaf, both sections must be made of steel at least 1/4 in. (0.6 cm)
thick. The U-shaped section of the shoe must be a minimum of 5 3/4 in. (2.1 cm) long and must be as wide as the gate leaf is thick and must fit as tightly as possible to minimize leaf movement within the shoe
(see Figure 11).
Construct the U-shaped section of the shoe and verify that it fits around the gate leaf. Position the U-shaped section over the splined shaft so that the leaf's axis of rotation will fall within the minimum dimensions shown in Figure 11.
On the U-shaped section of the shoe, mark the position for the leaf's axis of rotation. Next, drill a pilot hole in the U-shaped section to mark the axis of rotation point and mark the position for the placement of the vertical section of the shoe.
Next you need to position the sleeve for the splined shaft of the pinion (or the shear-pin assembly) on the bottom side of the U-shaped section of the shoe as shown in Figure 10. On the bottom of the U-shaped shoe section, center the sleeve around the pilot hole that marks the axis or rotation. Accurately centering the pilot hole is important.
Caution: NEVER weld the splined shaft to anything.

Spot-weld the sleeve into place on the bottom of the shoe's U-shaped section. If you are using the shear-pin assembly, spot weld the sleeve to the bottom of the shear-pin assembly, and spot weld the top of the shearpin assembly to the bottom of the shoe’s U-shaped section.
Next you must test the temporarily welded position of the splined shaft's sleeve. Fit the shaft sleeve over the splined shaft with the U-shaped section aligned in the gate leaf's fully closed position. Verify with a plumb line that the axis of rotation falls through the pilot hole to the center of the splined shaft.
If the axis of rotation alignments are correct, then permanently weld the sleeve for the splined shaft to the bottom of the U-shaped section of the shoe.
Also, you now need to weld the pilot hole closed, and you need to weld the vertical section of the shoe to the
U-shaped section of the shoe.
Lubricate the splined shaft with grease and place the finished gate leaf shoe over the shaft in the closed position.
Install the Gate Leaf
If you are not using the telescoping shear-pin assembly, install the gate leaf by placing its 90-deg corner into the gate leaf shoe and then installing the top gate hinge.
Installing the top gate hinge may require the gate leaf to be at a particular height. To raise (or lower) the gate leaf to the proper height, equally adjust the four leveling bolts on the base of the drive unit. The bolts raise (or lower) the splined shaft and thus the gate leaf shoe and gate leaf.
To test the installation of the gate leaf, first make sure that the hydraulic system has been disengaged (the
Manual Release lever should point down).
Next, very slowly open and close the gate leaf a few times to see if it moves smoothly and evenly through its entire path. As necessary, adjust the leveling bolts on the base of the drive unit to correct any problems with the gate’s travel.
Installing the Control Panel
Locate the control panel in the most convenient position possible, considering the movement of the gate. For example, a good position for the control panel box in on the inner face of the post or pillar. Figure 12 shows the typical layout for a two-leaf gate with the 750 Operator.
If you are embedding the control panel box into a wall or post, you must be sure to allow a clearance between the surface of the wall or post and the rim under the lid of the control panel box.
Installing the control panel consists of six general steps:
•
Connecting the main power to the control panel
•
Connecting the activating device
•
Connecting the operator to the control panel
•
Checking the direction of the motor's rotation
•
Connecting other devices (activating and reversing) to the control panel
•
Setting DIP switches and potentiometers for normal operation
The installer is responsible for grounding the gate and operator systems, for providing the main power breaker switch, and for making sure that the entire gate system meets all applicable electrical codes.

Connect the Operator(s) to the Control Panel
Figure 14. The terminal strip wiring of the 450 MPS
WARNING! Turn the main power off before you make any electrical connections or set any switches inside the control panel box.
Using a Junction Box
Connecting your operator(s) to the control panel may require the use of one or more junction boxes. Whether you need 0, 1, or 2 U.L. Listed junction boxes depends on your gate design (refer to Figure 15 below).
Note: The 750 Operators shipped for U.L. applications come with a U.L. listed junction box installed in the power unit box.
If any operator is more than 2 ft away from the U.L.
Listed control panel enclosure, the connection must be made inside a junction box. Use a U. L. Listed cord grip where the operator cord enters the junction box; use conduit between the junction box and the enclosure.
Connecting the Operator(s)
Caution: Do not use the terminal connections for Motor 2 (terminals 6, 7, and 8) if yours is a one-leaf gate design.
Note: If you have a one-leaf gate design, the operator must be connected to Motor 1
(terminals 3, 4, and 5).
If your gate system has one operator, connect the capacitor and the brown and black (or red and black) wires from your operator to the terminals 3 and 5 in block J2 for Motor 1. Connect the blue (or white) wire from the operator to terminal 4 for Motor 1.
Note: If you want to delay the closing of one gate leaf in a two-leaf gate design, be sure to connect its operator to Motor 1 (terminals 3, 4, and 5).
If your gate system has two operators, connect the second operator to terminals 6, 7, and 8 in block J2 for
Motor 2. Connect the capacitor and the brown and black
(or red and black) wires from the operator to terminals 6 and 8, and connect the blue (or white) wire from the operator to terminal 7 for Motor 2.
Adjust the Pressures for the Operator
WARNING! You must decrease the pressures of the gate’s opening and closing momentum before you operate the gate electrically. The pressure valves are not preset at the factory and may operate the gate leaf with enough force to endanger people and seriously damage the gate leaf itself.

Check the Motor’s
Direction of Rotation
After you have connected the main power supply, one activating device, and the operator(s) to the control panel, you need to check the direction of rotation for each operator motor in your gate design.
To check a motor’s direction of rotation, you must have three closed circuits on terminal block J3. Install one circuit between terminals 11 and 13, another circuit between terminals 13 and 21, and another circuit (or stop device) between terminals 14 and 15.
You cannot check the motor’s direction of rotation without these circuits (jumpers) or the accessories.
When properly prepared for testing, the LEDs DL2 and
DL3 should be illuminated. and stop devices. The instructions for installing such accessories follow.
Connect Other Devices
WARNING! Turn the main power off before you make any electrical connections or set any switches inside the control panel box.
Now you can connect additional reversing and activating devices to the control panel. Refer to Figure 13 for the general control panel layout, and refer to Figure 14 for the layout of the terminal strip.
Note: The 450 MPS control panel allows a maximum accessory load of 500 mA.
WARNING! Running the operator—even for testing purposes—without a connected reversing device is potentially dangerous. Do not place yourself within the path of the moving gate during your test.
Disengage the operator(s) with the Manual Release key, and open the gate by hand about halfway.
Next, engage the operator(s) with the Manual Release key so that you can check the rotation of the motor(s).
Turn on the main power and send an activating signal to the operator. The gate leaf (or leaves) should open. If a gate leaf closes, then you need to turn off the main power and reverse the connection of the brown and black (or red and black) wires on terminal block J2 for the operator controlling that leaf. Then you need to recheck the rotation direction again.
If your gate system has two operators, be sure the motor of each rotates in the correct direction.
After having completed your test of the motor’s direction of rotation, replace any test circuits you installed (between terminals 11 and 13, between 13 and
21, and between 14 and 15) with the proper reversing
Power Supply for Accessories: You can access a 30
VDC output for supplying power to accessories that require DC voltage through terminals 9 and 10 (located above the label 30 Vcc) on terminal block J3. In most cases, this source can be used to power 24 VDC accessories.
Reversing Devices: Reversing devices include photocells, inductive loops, and so forth. All of the reversing devices should have contacts of the normally closed (N.C.) type. Where you connect a device depends on whether you want the device to operate during opening or during closing.
Note: UL does not recognize the FAAC system with loop detectors or safety edges.
FAAC photocells must be used to comply with
UL 325.
Caution: Failure of a reversing device that operates during opening causes a gate to lock in the closed position and requires the use of the manual key release.
To wire photocells, refer to Figure 14 (see FSWOP for opening photocells, and FSWCL for closing photocells— connect the photocells exactly as shown). See Figure 17 for the wiring of inductive loops. In either case, if you have multiple devices, wire them in series.

EP on on off
B on on on
C off off on
Adjust the Potentiometers
The four potentiometers control the torque (or pressure), the pause time between opening and closing, the opening/closing time of operation, and the leaf delay on closing.
Torque (Pressure): The torque (or pressure) potentiometer on the 450 MPS must be turned all the way clockwise for the 750 Operator. The potentiometer controls voltage to the operator, which can affect the life of the operator’s motor. The torque/pressure potentiometer cannot be used to adjust the operator’s hydraulic operating pressures.
Caution: Failure to turn the torque/pressure potentiometer to maximum in the clockwise direction jeopardizes the life of the motor of your operator.
WARNING! Adjust the operating pressure on the 750 Operator only by means of the hydraulic bypass valve screws. See pages 18 and 24.
23
Pause Time: The pause time between opening and closing can be adjusted from 5 to 240 seconds. Turn the potentiometer clockwise to increase the pause time and counterclockwise to decrease the pause time.
Opening/Closing Time: The opening/closing time is adjustable from 10 to 62 seconds. The approximate opening/closing time for a 90-degree opening is 18 seconds. Turn the potentiometer clockwise to increase the time and counterclockwise to decrease the time.
For optimal operation, set the time so that the motor remains active for a couple of seconds after the leaf has reached its limit stop for opening and for closing.
Leaf Delay: You may choose to delay one leaf on closing for overlapping gate leaves. Be sure the operator on the leaf for delayed closing is connected to Motor 1.
On opening, the leaf connected to Motor 2 is delayed
2.5 sec.
Note: You cannot adjust this opening delay of the operator connected to Motor 2. However, you can avoid the opening delay—and closing delay—by connecting both operators (and their capacitors) to Motor 1.
The time is adjustable from 0 to 28 seconds. Turn the potentiometer clockwise to increase the time and counterclockwise to decrease the time.
Note: If one-leaf gate designs, be sure to set the potentiometer for leaf delay to its minimum
(0 seconds).
Note: If the opening/closing time is set at less than the leaf delay time, the delayed leaf closes at the end of the closing time.
Bleeding the
Hydraulic System
For the 750 Operator to work smoothly, it is critical that you bleed the hydraulic system of any air. Before you bleed the system, be sure that you have removed the vent screw on the top, left side of the power unit.
One bleeding operation consists of the following:
•
Running the gate leaf through three openclose cycles
•
Allowing the gate leaf system to sit idle for
5 minutes
•
Releasing the air from each end of the drive unit through the bleed screw holes (see Figure 18)
24
You need to bleed the hydraulic system before setting the gate up for normal operation.
To run the gate leaf through an open-close cycle, make sure the gate is set up for hydraulic operation (the
Manual Release lever is turned up) in the A mode.
Activate the gate once to open, pause, and then automatically close. The gate needs to open and close three times.
Then you need to allow the gate to sit idle for a full five minutes. During this time, you can disengage the hydraulic system (turn the Manual Release lever down) and make sure that the top cover is removed from the drive unit to allow you access to the bleed screws on either end of the unit.
With the hydraulic system disengaged, open the gate leaf by hand to a half-opened position. Re-engage the hydraulic system.
If you have a CBAC model of the 750 Operator (with hydraulic locking in the fully opened and fully closed positions), then first try to move the gate leaf. If you are unable to make the gate leaf move, then you do not need to bleed the hydraulic system.
If you do need to bleed the hydraulic system, then next open the bleed screw that is on the same side of the drive unit as you are. Open the screw less than a full turn. Next, pull the gate leaf toward you until just oil
(and no bubbles) comes out of the drive unit. Then close the bleed screw.
Next, release the air from the other end of the drive unit in the same manner.
Finally, test the automatic operation of the gate. If the gate does not operate smoothly, then repeat the bleeding process again.
Adjusting the Bypass Valves
The pressure a gate leaf applies to an obstacle in its path is determined by the bypass valve adjustment. FAAC recommends that the gate should stop when it meets with a force of more than 33 lb (15 kg).
WARNING! The pressure valves may operate the gate leaf with enough force to endanger people and seriously damage the gate leaf itself. Increase the pressures in small increments (1/4 turn), and set the pressure adjustments at the minimum level necessary for the gate's operation.

WARNING! The pressure the gate leaf applies to the obstruction is determined by the bypass valve adjustment. It is the installer's responsibility to make sure the pressures are correctly set.

Installing an Extension Arm
Some gate installations do not meet the geometrical constraints shown in Figure 2. In those situations, the
750 Extension Arm option can be used along with the
750 drive unit, power unit, and control panel to install an unobtrusive gate operator.
Using the 750 Extension Arm means that you do not have to permanently remove any leaf hinges, the gate leaf does not need to form a 90-deg angle on the bottom corner nearest the gate post, and the relative location of the rotation axis is not so restricted.
The geometrical constraint for using the 750 Extension
Arm is that the center of the splined shaft on the drive unit must be within 6 in. (15.25 cm) of the axis of rotation of the gate leaf.
WARNING! The farther away the splined shaft is from the gate's axis of rotation, the greater the risk of danger from pinch points.
Install the drive unit so that the splined shaft is as near as possible to the gate's rotation axis and is directly beneath the center of the fully closed gate leaf.
You need to position the extension collar (see Figure
23) so that it smoothly slides within the extension U from the fully closed to the fully opened position. Note that the position of the extension collar is affected by the overlap of the extension bar and extension U.
Attach the 750 extension collar to the bottom of the gate leaf with a 7/16 in. (1.1 cm) bolt.
Weld together the extension bar and extension U according to Figure 23.
Caution: Do not weld anything to or on the inside of the sleeve of the splined shaft.
Next, weld the outside of the sleeve for the splined shaft solidly to the inside of the hole in the end of the extension bar.
Follow the rest of the instructions for installing the 750
Operator. With an extension arm, you need not worry about installing a gate leaf shoe nor about installing the gate leaf in the shoe. Instead, you will install one end of the welded extension arm over the splined shaft and the other end around the extension collar.
In addition, you will need to provide a washer beneath the extension collar to keep the extension U from falling off the collar. You also need to shield any pinch points around the extension arm.

Maintenance
The 750 Operator
The FAAC recommended maintenance schedule varies according to the frequency of use of the operators, whether lightly used operators (once or twice an hour) or heavily used operators (many cycles per hour).
Check the oil.
To check the oil level correctly, remove the oil filler cap on the top of the power unit. A dip stick is attached to the bottom of the cap for checking the oil level as shown in Figure 24.
Light duty use: check once per year
Heavy duty use: check every 6 mo
Change the oil.
Changing the oil completely in the hydraulic system of the 750 Operator requires removing the power unit and drive unit from their installed positions unless you are able to pump the oil out of both units.
Light duty use: change every 4 yr
Heavy duty use: change every 2 yr
Figure 24. When you check the oil, make sure the oil level falls between the minimum and maximum marks on the oil dip stick
Check the pressure settings.
Light duty use: check once per year
Heavy duty use: check every 6 mo
Check all reversing devices.
Every six months, you should verify that all installed reversing devices work properly.
The Control Panel
The control panel requires no maintenance.
Troubleshooting
Problem: The gate does not respond to an activating signal.
Solution:
Verify that you have correctly wired the operator to the control panel.
Verify that the LED DL3 is on. If it is not illuminated, then check the fuses on your control panel.
If the LED DL3 is not illuminated and your fuses are okay, then the stopping device is being triggered and is preventing the gate from responding to your signal. If you have no stopping device installed, then be sure you have installed a jumper across the appropriate terminals.
Verify that your activating device works properly. Either
DL1 or DL2 (depending on your gate design) should illuminate when you signal the gate to close (or open) and LED DL3 should be on. If either DL1 or DL2 does not illuminate when you signal the gate, then the problem may be in your activating device. Short across the appropriate terminals. If the short causes the gate to
27
close (or open), then the problem is in the activating device. Repair or replace the device.
Problem: The radio controlled opener does not open the gate.
Solution:
Check the light on the front of the remote transmitter. It should illuminate when you signal the gate. If it does not illuminate and if the batteries are okay, repair or replace the transmitter.
Verify that the wiring for the radio controlled device is correct.
Check the wiring for the antenna and correct it if necessary.
Check DL1 and DL2. One should illuminate when the transmitter button is pressed.
Determine if the fault is in the receiver by temporarily connecting a push button device across the appropriate terminals. If such a push button device opens the gate, repair or replace the receiver.
Problem: The gate doesn't open (or close) though the motors are running.
Solution:
Make sure that the motor is running in the right direction, and make sure the Manual Release mechanism has fully engaged the hydraulic system.
Increase the bypass pressure in small
1
/
4
turn increments to see if the hydraulic system needs more pressure.
Problem: The gate opens but does not close.
Solution:
Make sure you have selected the desired operating mode.
Verify that the reversing devices are working properly.
DL4 or DL5 should illuminate when a reversing device is triggered. If either does not illuminate, then one of your reversing devices is preventing the gate from responding to your signal. Check your reversing devices.
If no reversing devices are installed, make sure a circuit is installed between appropriate terminals.
If the motor is running, insure that the bypass valves are
1 correctly adjusted. Increase the bypass pressure in small
/
4 turn increments to see if the hydraulic system needs more pressure.
Problem: The gate does not fully open (or close).
Solution:
Increase the bypass pressure(s) to see if the hydraulic system needs more pressure.
Check the operator's motor run time selection. You should set a time that is just longer than the rated speed of your model of operator. For example, because the 400
CBAC has a rated opening time of 17 sec, you should select a time that is just longer than the opening time.
Check to see that there are no obstructions in the path of the gate or that the hinges are not binding.
Problem: The operator doesn't work smoothly and the gate jerks as it opens and closes.
Solution:
Check the oil level in the operator.
Make sure the Manual Release mechanism has fully engaged the hydraulic operation of the operator.
Bleed the air from the hydraulic system by cycling the gate (opening and then closing) 10 times and pausing for a couple of minutes between cycles.
Make sure that a flexible gate leaf is not the problem. If the gate leaf flexes, then stiffen the gate or use a slower operator.
