Terminal Block J6 - Limit-Switches: Dedicated to the connection of opening and closing limit switches.

6. Connection of Safety Devices

Entrapment Protection: To comply with UL325, every entrapment zone must be protected by two independent entrapment protection devices. One device is inherent in the FAAC system; the other can be external, like a photocell or edge sensor.

Opening Safety Devices: Active during opening movement, protecting the area between leaves and obstacles against entrapment risk.

Closing Safety Devices: Active during closing movement, protecting the closing area against entrapment risk.

Monitored Devices: UL325 requires all external entrapment protection devices to be monitored for presence and correct operation. Closing safety devices are always monitored. Note: One closing safety device must always be connected for the system to function.

Monitoring of Opening Safety Devices: Enable this function in advanced programming by setting the "FS" parameter to "Active".

ADVANCED PROGRAMMING (F) + +:

• Display: FS
• Function: OPENING FAIL SAFE: Enables monitoring of opening safety photocells before opening. If the test fails, the gate does not open.
• Default: 4 = Active, = Disabled

Connection of One Pair of Monitored Closing Photocell and One Pair of Monitored Opening Photocell: Diagrams illustrate wiring for monitored closing and opening photocells.

OPENING No. 2 FAIL SAFE: When enabled, the STOP input can be used for a second monitored opening safety device.

• Default: 4 = Active, = Disabled

Connection of One Pair of Monitored Closing Photocells: Diagrams illustrate wiring for monitored closing photocells.

Connection of Two Pairs of Closing Photocells, One Monitored and One Non Monitored: Diagrams illustrate wiring for monitored and non-monitored closing photocells.

Connection of a pair of Monitored Closing Photocells, and one pair of Non Monitored Opening/Closing Photocell: Diagrams illustrate wiring for monitored closing and non-monitored opening/closing photocells.

Connection of One Pair of Monitored Closing Photocells, One Pair of Monitored Opening Photocells and One pair of Non Monitored Opening/Closing Photocells: Diagrams illustrate wiring for monitored closing, monitored opening, and non-monitored opening/closing photocells.

Opening/Closing Safety Devices: These devices operate during gate movement and protect against impact. They can be used in conjunction with other monitored photocells, but cannot be monitored themselves.

7. Operating Logics

This section provides a brief description of the main operating logics:

• E (Semi-automatic): Requires a command to open and a command to close. Opening is stopped by a second command; closing is reopened by a second command.
• A (Automatic): Gate opens on command and closes automatically after a pause time. Second commands during opening are ignored. A command during the pause phase interrupts it. A command during closing reopens the gate. A maintained open command holds the gate open.
• S (Security): Similar to logic A, 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 a command to open and a command to close. A second command during opening or closing stops the gate. A third command reverses the gate's motion.
• B (Manned, pulsed): Designed for guard station use, requiring a three-button switch (pulsed) to open, close, and stop the gate.
• C (Manned and constant): Requires constant pressure switches for opening and closing. Releasing a switch stops the gate.

The following table displays the sequence of functions accessible in BASIC PROGRAMMING:

(*) For hydraulic operators, set force to the maximum level.

8. Programming

Programming the 455D Control Board involves two parts: BASIC and ADVANCED.

Basic Programming:

• Press and hold 'F'. The unit displays the name of the first function/parameter.
• Release 'F'. The unit displays the current value. Modify with '+' and '-'.
• Press and hold 'F' again to display the next function/parameter.
• Press 'F' on the last function to exit programming. The display resumes monitoring input status.
• IMPORTANT: Exit programming mode to save changes. Unsaved modifications are lost if power is lost before exiting.

Advanced Programming:

• Press and hold 'F', then press '+'.
• Release '+'. The unit displays the name of the first function.
• Release 'F'. Modify the value with '+' and '-'.
• Press and hold 'F' to display the next function. Release 'F' to modify its value.
• Press 'F' on the last function to exit programming.

The following table shows the sequence of functions accessible in ADVANCED PROGRAMMING:

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

9. Start-up

LED Indicators: The two-digit display indicates input status when not in "PROGRAMMING" mode. The table below shows LED mapping to inputs.

Operation of the Status Signaling LEDs:

Note: LED ON = closed contact, LED OFF = open contact. Bold indicates status when the gate is closed at rest.

The display shows the status of safety inputs clear and no activation signal present.

Rotation direction and force check:

1. Program the 455 D control board functions as needed.
2. Turn power off to the control board.
3. Release operators and manually move the gate to the mid-point of the opening angle.
4. Re-lock the operators.
5. Restore power.
6. Send an opening command on the OPEN A input and verify gate leaves move towards the open position. (Note: If the first OPEN A pulse starts a closing movement, turn power off and reverse the phases of the electric motor wires on the 455 D control board).
7. Check motor force setting and adjust if necessary. (Note: For hydraulic operators, set force to maximum level 50).
8. Stop leaf movement with a pulse on the STOP input or by turning off power.
9. Release operators, close leaves, and re-lock them.

Opening/closing time is established by a time learning procedure ("simple" or "complete" modes). The "simple" mode does not allow a slow down phase, while the "complete" mode does. Slow down can reduce mechanical stress but may cause issues in high wind conditions.

10. Learning Operating Times

WARNING: Safety devices are disabled during the learning procedure. Avoid crossing the leaf movement area.

Ensure travel limit mechanical stops are present.

SIMPLE LEARNING (Without Slow Down):

1. Check leaves are closed. Enter "BASIC PROGRAMMING", select TIME LEARNING, and press '+' for 1 second. Display flashes, leaves open.
2. As leaves reach the opening contact point, provide an OPEN A pulse (key or radio control) to stop movement. Display stops flashing.
3. Press 'F' to exit and save. Gate is ready.

COMPLETE LEARNING (With Slow Down):

1. Check leaves are closed. Enter "BASIC PROGRAMMING", select TIME LEARNING, and press '+' for more than 3 seconds. Display flashes, leaf 1 opens.
2. Perform 8 OPEN A pulses (key or radio control) for the following functions:
1. Slow down at opening of leaf 1
2. Leaf 1 stops at opening; leaf 2 begins opening.
3. Slow down at opening of leaf 2
4. Leaf 2 stops at opening and immediately begins closing.
5. Slow down at closing of leaf 2
6. Leaf 2 stops at closing; leaf 1 begins closing.
7. Slow down at closing of leaf 1
8. Leaf 1 stops at closing
3. When display stops flashing, press 'F' to exit and save. Gate is ready.

Notes:

• To eliminate deceleration in 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, the entire sequence must still be completed. After leaf opening, supply 5 Open pulses until the leaf begins to close, then resume normal operation.

11. Final Tests

After programming, perform a complete test of the system. Verify operator function, force adjustment, and safety device operation.

After learning, the board adds 3 seconds to programmed time, causing operators to run against stops.

Monitored Safety Test:

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

12. Operating Modes Detailed Description

This section details various operating modes (Logics E, A, S, EP, AP, SP, B, C) and their behavior with different pulses and safety device activations. Tables 3/a through 3/h provide comprehensive descriptions of each logic's response to OPEN-A, OPEN-B, STOP pulses, and the effect of Opening Safety Devices, Closing Safety Devices, and OP/CL SAFETY DEVICE.
