3. Product Overview and Components
The Dieffematic Electronic Control Unit is a printed circuit board (PCB) designed to manage the functions of an automatic sliding gate. It integrates various electronic components, connectors, and control elements.
Figure 1: Dieffematic Electronic Control Unit. This image displays the green circuit board with various electronic components, including capacitors, resistors, integrated circuits, a transformer, and multiple green screw terminal blocks for electrical connections. A white warning label is visible on one of the components.
Key components typically include:
- Power Input Terminals: For connecting the main power supply.
- Motor Output Terminals: For connecting the gate motor.
- Safety Device Inputs: Connections for photocells, safety edges, and emergency stop buttons.
- Command Inputs: For connecting push buttons, key switches, or radio receivers.
- Indicator LEDs: To show operational status and diagnostics.
- Programming Buttons/DIP Switches: For configuring operational parameters.
4. Setup and Installation
Before beginning installation, ensure the main power supply to the gate automation system is disconnected. Refer to the original gate operator manual for specific wiring diagrams if available, as this unit is a compatible replacement.
4.1 Mounting the Control Unit
- Mount the control unit inside a suitable, weather-resistant enclosure, away from direct sunlight and moisture.
- Ensure adequate ventilation around the unit.
- Secure the board using appropriate fasteners to prevent vibration.
4.2 Electrical Connections
Carefully identify each terminal block on the control unit. The layout is generally consistent with FAAC 780D/7909212 boards. Use the following as a general guide:
- Power Supply (230V AC or 115V AC, depending on model): Connect the main power to the designated input terminals (e.g., L, N, Earth).
- Motor Connections: Connect the motor windings (e.g., Common, Open, Close) to the motor output terminals.
- Capacitor: If your motor requires a starting capacitor, connect it as per the motor's specifications.
- Safety Devices (Photocells, Safety Edges): Connect these devices to their respective normally closed (NC) or normally open (NO) inputs. Ensure proper alignment and functionality.
- Command Devices (Push Buttons, Key Switches, Radio Receiver): Connect these to the appropriate command inputs (e.g., Open, Close, Stop, Pedestrian).
- Flashing Light/Courtesy Light: Connect to the designated output terminals.
After all connections are made, double-check wiring for correctness and security before restoring power.
5. Operating and Programming
Upon initial power-up, the control unit may require a learning cycle or parameter configuration. Refer to the specific programming instructions for FAAC 780D or 7909212 control units, as this Dieffematic board is designed to emulate their functionality.
5.1 First Power-Up and Learning Cycle
- Restore power to the system.
- Observe the indicator LEDs for status.
- Initiate the gate's learning cycle (auto-set) as per the original FAAC manual's instructions for setting limits and force. This typically involves pressing a specific button or sequence of buttons.
- Ensure the gate travels its full open and close cycles smoothly and stops correctly at the limits.
5.2 Adjusting Parameters (DIP Switches/Potentiometers)
Many control units feature DIP switches or potentiometers for fine-tuning parameters such as:
- Operating Logic: Automatic, semi-automatic, condominium mode.
- Pause Time: Duration before automatic closing.
- Motor Force: Adjustment of motor power.
- Soft Stop/Start: Enabling or disabling gradual acceleration/deceleration.
- Safety Input Configuration: NC/NO selection for photocells.
Consult the specific FAAC 780D/7909212 programming guide for detailed parameter settings.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your gate automation system. Always disconnect power before performing any maintenance.
- Visual Inspection: Periodically check the control unit for any signs of damage, loose connections, or corrosion.
- Terminal Tightness: Ensure all screw terminals are securely tightened.
- Enclosure Integrity: Verify that the control unit's enclosure is sealed and free from water ingress.
- Safety Device Check: Regularly test photocells and other safety devices to ensure they function correctly.
- Gate Mechanics: Inspect the gate's mechanical components (wheels, track, motor) for smooth operation and lubrication.
7. Troubleshooting
This section provides solutions to common issues. For complex problems, contact a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Gate does not move. | No power; Blown fuse; Safety device activated; Motor fault. | Check power supply; Replace fuse (after identifying cause); Check photocells/safety edges; Consult technician. |
| Gate opens but does not close. | Photocells obstructed or misaligned; Safety edge activated; Programming error. | Clear obstruction, align photocells; Check safety edge wiring; Review programming parameters. |
| Gate stops unexpectedly. | Obstruction detected; Motor overheating; Limit switch issue. | Remove obstruction; Allow motor to cool; Check limit switch connections and functionality. |
| Remote control not working. | Dead battery; Receiver not connected; Remote not programmed. | Replace battery; Check receiver wiring; Program remote control as per receiver instructions. |
