Installing the Warning Signs

This FAAC swing gate operator is supplied with two warning signs to alert people that a possible hazard exists and that appropriate actions should be taken to avoid the hazard or to reduce exposure to it.

Permanently install one warning sign on each side of the gate so they are fully visible to traffic and pedestrians. Use appropriate hardware such as metal screws (not supplied) to permanently install each warning sign.

400 OPERATOR

The self-contained 402 operator is an electro-hydraulic unit consisting of an electric motor, a pump, a valve assembly, and a hydraulic cylinder, all housed in an anodized aluminum oil reservoir. All models of the 402 operator have one hydraulic lock. The CBC version is designed to lock when the piston is extended. The optional CBA version is designed to lock when the piston is retracted. The hydraulic lock is a service device rather than a security device. Additional external locks are recommended if tight security is needed.

The 402 operator is designed and built to automate vehicular swing leaf gates. Do not use for any other purpose.

1. DESCRIPTION AND TECHNICAL SPECIFICATIONS

1.1. DIMENSIONS

Diagram (Fig. 2) shows the 402 operator's dimensions. Key dimensions are:

• A: 37 3/4 in
• B: 26 1/8 in
• C: 9 1/2 in
• D: 3 3/8 in
• E: 2 3/8 in

Diagram (Fig. 1) illustrates the internal components: 1. Electric motor, 2. Hydraulic piston, 3. Cylinder, 4. By-pass valves, 5. Pump unit, 6. Front bracket, 7. Housing, 9. Rear bracket.

1.2. WIRING

Diagram (Fig. 3) shows typical wiring for accessories like photocells, control units, push-buttons, radio receivers, warning lights, and electric locks. It emphasizes separating low-voltage accessory cables from high-voltage power cables using separate conduits. The installer is responsible for grounding, providing a main power breaker, and ensuring compliance with electrical codes. Controls should be located at least 6 ft from moving parts.

2. INSTALLATION

2.1. PRELIMINARY CHECKS

To ensure a correctly operating automated system, the structure of the existing gate or gate to be built must satisfy the following requirements:

• Leaf dimensions are within the limits specified in Table 1.
• The gate swings level.
• Smooth, uniform leaf movement, without any irregular friction during the entire travel.
• Existing hinges in good condition.
• Positive stops are provided in the fully opened and closed positions.

2.2. INSTALLATION DIMENSIONS

Inward swinging gate, top view (Fig. 4a):

Notes for inward swing: D: If greater than 2 in., a recess must be constructed. E: Must be less than A. Z: Must be 2 in minimum to avoid mechanical interference.

Outward swinging gate, top view (Fig. 4b):

Notes for outward swing: E: Must be less than A.

Diagram (Fig. 5) shows how to carve a niche in the column if dimension D prevents reaching the required dimension A. Dimension (1) is "A" - 2 in., and dimension (2) is "B" + 4 in.

2.3. GENERAL RULES

If the dimensions indicated in table A or B cannot be obtained, the following general rules can be used to determine different installation dimensions:

• To obtain 90° opening of the leaf: a + b = rod stroke.
• To obtain over 90° opening of the leaf: a + b < rod stroke.
• Lower 'a' and 'b' dimensions will result in higher speeds.
• Limit the difference of the 'a' and 'b' dimensions to within 1.5 in; higher differences will create high speed variations during the opening and closing movement.
• If the column dimensions or the position of the hinge (dimension D) do not make it possible to reach the required 'A' dimension, a niche must be carved in the column as shown in Fig. 5.

2.4. INSTALLATION OF THE OPERATOR

Installing the model 402 operator consists of the following steps:

1. Attach the rear mounting bracket.
2. Attach the operator to the rear mounting bracket.
3. Attach the front mounting bracket to the operator.
4. Attach the operator to the gate.
5. Adjust the hydraulic pressures for the operator.

Attach the rear mounting bracket: Attach according to dimensions in Figure 4a or 4b. WARNING: Ensure dimensions A and B are achieved; modification of the rear bracket may be necessary. If the gate post is steel, weld the bracket directly. If it's another material, use an optional mounting plate and weld the bracket to it. For outward swing gates, refer to Figure 4b.

Attach the mounting hardware: Place the operator with pressure adjusting screws facing up. Insert the mounting fork into the operator's rear flange, secure with the long brass pin and self-locking nut. Attach the fork assembly to the rear mounting bracket using the short pin, washer, and nut.

Attach the front mounting bracket to the operator: Insert the triangular key into the manual release mechanism on the underside of the operator and turn counter-clockwise one turn. For inward swing, pull the piston out and push it back inward approximately 1/4" (6mm). For outward swing, push the piston in completely and pull it back out approximately 1/4" (6mm). Diagram (Fig. 8) shows pushing the front pin through the front mounting bracket and then the piston rod to temporarily attach them.

Make sure the operator is level and the gate is against the closed positive stop. Hold the front mounting bracket flush against the gate, mark its location, remove the operator, and then remove the front mounting bracket from the piston rod.

Diagram (Fig. 9) shows spot welding the front bracket on the leaf, protecting the rod from welding splatter. WARNING: Do not weld the front mounting bracket with the operator attached, as this will damage the operator. Ensure the gate structure allows firm fastening, or create a solid support base. Release the operator and manually check if the gate moves freely, stops at positive stops, and operates without friction. Complete welding the front bracket to the gate leaf.

Attach the operator to the gate: Re-attach the operator to the mounting brackets. Once mounted and level, remove the vent screw from the bottom of the valve body (Fig. 11, ref 1) using a 3mm hex wrench. WARNING: Failure to remove the vent screw may result in erratic operation or blown seals. Slowly move the gate open and close; the piston should not bottom out. Ensure the gate reaches the positive stop before the piston bottoms out. Attach the connector with the cable and secure it with screws (Fig. 12), ensuring the strain relief is tight. Slip the cover over the operator with the slit facing the gate, ensuring it's firmly placed over the rear of the operator cover (Fig. 13, ref 1). Secure the cover with self-tapping screw (2). Fix the end cap (3) to the cover using black plastic screws (4).

2.5. BY-PASS VALVES ADJUSTMENT

The 402 operator has an anti-crushing safety device that limits the operator's force if an obstacle is encountered. To adjust this system, turn the By-Pass screws on the flange (Fig. 14).

• OPEN screw (green): gate opening direction.
• CLOSE screw (red): gate closing direction.

(The opposite applies in case of outward opening). To reduce pressure, turn screws anti-clockwise. To increase pressure, turn screws clockwise. After adjustment, attach the protective plastic cover over the by-pass screws using supplied self-tapping screws.

3. MANUAL OPERATION

If the gate must be moved manually due to a power outage or other failures, use the manual release device as follows:

• Insert the triangular key into the release screw located in the lower part of the flange (Fig. 15).
• Turn the release key counter-clockwise for about two turns.
• Open or close the leaf manually.

To re-lock the operator, turn the key clockwise until it stops.

4. MAINTENANCE

Run a functional check of the system at least every 6 months. Pay special attention to the efficiency of the safety and release devices (including thrust force) and the perfect operation of the gate hinges.

Checking oil level:

Periodically check the oil level inside the tank:

• Cut power to the system.
• Position the operator vertically, with the rear flange high up.
• Remove the oil filling plug.
• Insert a screwdriver until it contacts the electric motor (as shown in Fig. 16).
• Remove the screwdriver and check the oil level (as shown in Fig. 16).

USE ONLY FAAC HP FLUID OIL

Periodically check the correct adjustment of the anti-crushing safety device (BY-PASS) and the efficiency of the release system to allow manual operation. The safety devices installed on the system must be checked every 6 months.

REPAIRS: For any repairs, contact FAAC's authorized Repair Centers.

6. Connection of Safety Devices

Entrapment Protection

To comply with UL325, every entrapment zone must be protected by two independent entrapment protection devices. One is inherent to the FAAC operator/board, the other can be external (e.g., photocell or edge sensor). See diagram for photocell positioning (16" or less).

Monitoring of opening safety devices must be enabled in the board configuration. Access advanced programming by holding "F" and pressing "+", scroll to "FS" parameter, and select "Active".

OPENING FAIL SAFE: If activated, enables monitoring of the opening safety photocell before opening movement. If the test fails, the gate does not open. (Default: Disabled).

Diagrams show wiring for monitored closing and opening photocells, and non-monitored devices.

Opening Safety Devices: Active during opening movement, protecting areas between leaves and obstacles.

Closing Safety Devices: Active during closing movement, protecting closing areas against entrapment.

Monitored Devices: UL325 requires external entrapment protection devices to be monitored for presence and correct operation. Closing safety devices are always monitored. See diagrams for wiring. NOTE: One closing safety device must always be connected for the system to work.

Additional Monitored Opening Safety: Connect photocell directly to the 455D board STP input. Advance Programming: "FS" = Active. Remove jumper from Pin 11 if present.

Maglock or Solenoid connection: The prewired enclosure has a terminal block for Maglock or DC Solenoid connection. Set jumper JP1 according to the device used. Rating: 24VDC - 500 mA.

Loops connection: The prewired enclosure includes connectors for 10-pin plug-in loop detectors and a terminal block for safety loop wiring.

7. Operating Logics

This section describes the main operating logics:

• E (semi-automatic): Requires a command to open and a command to close. A second command during opening stops the gate; a second command during closing reopens it.
• A (automatic): Gate opens on command and closes automatically after pause time. A second command during opening is ignored. A second command during pause interrupts pause time. A second command during closing reopens the gate. A maintained open command holds the gate open.
• S (security): Similar to A logic, but a second command during opening immediately closes the gate. A maintained open command does not hold the gate open.
• EP (semi-automatic, step by step): Requires an open command and a close command. A second command during opening or closing stops the gate. A third command reverses the previous motion.
• B (manned, pulsed): Designed for guard stations; requires a three-button switch (pulsed) to open, close, and stop.
• C (manned and constant): Requires constant pressure switches for opening and closing. No pressure on a switch stops the gate.

8. Programming

To program the 455D Control Board, access "PROGRAMMING" mode, which is split into BASIC and ADVANCED.

Basic Programming:

Press and hold key F to display the first function/parameter. Release key to view the current value. Use keys + and - to modify values. Press and hold F again to move to the next function. Press F to exit programming.

The table shows functions accessible in BASIC PROGRAMMING:

Note: For hydraulic operators, set force to the maximum level.

Advanced Programming:

Access ADVANCED PROGRAMMING by pressing and holding F, then pressing +. Release + to see the first function. Release F to modify the value with + and -. Press and hold F to move to the next function. Press F to exit.

The table shows functions accessible in ADVANCED PROGRAMMING:

Note: Parameter modifications take effect immediately. Exit programming to save changes. Unsaved modifications are lost if power is lost before exiting. To restore defaults, press and hold +, -, F simultaneously for 5 seconds.

9. Start-up

LED Indicators:

The two-digit display shows input status when not in "PROGRAMMING" mode. The LED segments map to inputs as shown in the diagram. LED ON indicates a closed contact; LED OFF indicates an open contact.

Operation of the Status Signaling LEDs: Table details LED status (ON/OFF) for inputs like OP_A, OP_B, STOP, FSWCL, FSWOP, FCA1, FCC1, FCC2, FCA2, relating to commands and limit switches.

Rotation direction and force check:

1. Program functions according to need.
2. Turn power off.
3. Manually move the gate to the mid-point of the opening angle.
4. Re-lock operators.
5. Restore power.
6. Send an opening command (OPEN A input) and verify gate leaves move towards open position. (If direction is reversed, turn power off and reverse motor wires).
7. Check and adjust motor force if necessary. For hydraulic operators, set force to maximum (50).
8. Stop leaf movement via STOP input or power off.
9. Release operators, close leaves, and re-lock.

Opening/closing time is established by a time learning procedure ("simple" or "complete" modes). Simple mode lacks a slow-down phase; complete mode includes it. Slow-down can reduce mechanical stress but may cause issues in high winds.

10. Learning Operating Times

WARNING: Safety devices are disabled during learning. Avoid the leaf movement area. Ensure travel limit mechanical stops are present.

• SIMPLE LEARNING (Without Slow Down): Close leaves. Enter "BASIC PROGRAMMING", select TIME LEARNING, press + for 1 second. Display flashes, leaves open. Provide OPEN A pulse at opening contact point to stop. Press F to exit and save.
• COMPLETE LEARNING (With Slow Down): Close leaves. Enter "BASIC PROGRAMMING", select TIME LEARNING, press + for > 3 seconds. Display flashes, leaf 1 opens. Perform 8 OPEN A pulses for functions like slow down, stopping, and leaf transitions. Press F to exit and save.

Notes: To eliminate deceleration at certain stages, wait for the leaf to reach its stop-limit and supply 2 consecutive Open pulses (1 second each). If only one leaf is present, complete the sequence. After leaf opening, supply 5 Open pulses until it begins to close, then resume normal operation.

11. Final Tests

After programming and learning operating times, perform a complete system test. Verify operator function, force adjustment, and safety device operation. The system adds 3 seconds to programmed times to ensure operators run against stops.

Monitored safety test: To ensure monitored safety photocells are working, install a temporary jumper on the N.C. output of the photocell and give an OPEN A command. The gate must not move. Otherwise, check wiring and ensure FAIL SAFE is enabled in Advanced Programming.

12. Operating Modes Detailed Description

Tables 3/a through 3/h detail the behavior of different operating logics (E, A, S, EP, AP, SP, B, C) based on gate status (CLOSED, OPEN, CLOSING, OPENING, LOCKED) and pulse inputs (OPEN-A, OPEN-B, STOP), considering safety devices.

13. Prewired Enclosure

The 455D board is supplied in an enclosure integrating a Power ON-OFF switch, accessory power outlet, loop detector connectors, operator capacitors, and a terminal strip for AC power connection. Diagram shows enclosure layout.

AC Power Wiring Guidelines:

1. Follow local wiring and building codes. Wiring and hookup must be performed by qualified electricians/installers only.
2. AC power must be supplied from a circuit breaker panel with its own dedicated breaker, including a green ground conductor.
3. Properly ground the gate operator to minimize damage from power surges/lightning. Use a grounding rod if necessary. A surge suppressor is recommended.

Monitored safety connections: The prewired enclosure has a dedicated terminal block for monitored safety photocell connections. Diagrams show examples for monitored closing and opening safety devices, and non-monitored devices. IMPORTANT: The operator requires the closing safety photocell connection to function.

Additional Monitored Opening Safety: Connect photocell to the 455D board STP input.

Maglock or Solenoid connection: The enclosure includes a terminal block for Maglock or DC Solenoid connection. Set jumper JP1 according to the device used (Rating: 24VDC - 500 mA).
