- LED Display (8.8.): Shows operational status, programming values, and error codes.
- Control Buttons (Dec/Smart, Func, Inc/Start, Touch, Learn): Used for programming and manual control.
- DIP Switches: For setting various operational parameters and modes.
- USB Port: Potentially for firmware updates or advanced configuration.
- Status LEDs (Smart, State, Rf, Charge): Provide visual feedback on the board's current state.
4. Setup and Installation
4.1 Wiring Connections
- Power Supply (24V AC): Connect the main 24V AC power supply to the designated red terminal block labeled "24V AC" on the top right of the board. Ensure correct polarity if applicable.
- Battery Backup (BAT+): Connect a compatible backup battery to the red terminal block labeled "BAT+" on the bottom right. Observe correct polarity (+ to +).
- Motor Connections: Connect the gate opener motors to the green terminal blocks labeled "Motor1" and "Motor2(Main)" at the bottom of the board. Refer to your gate opener's specific wiring diagram for motor connections.
- Accessory Connections: Connect any external accessories such as photocells, keypads, loop detectors, or safety sensors to the appropriate green terminal blocks. Consult the detailed wiring diagram provided with your complete gate opener system for specific terminal assignments.
- Antenna: Connect the RF antenna to the designated port for remote control functionality.
4.2 Initial Configuration (DIP Switches)
The DIP switches (labeled 26-30 and 1-12) are used to set fundamental operating parameters. Refer to the specific configuration guide for your gate opener system to correctly set these switches for functions such as:
- Operating mode (e.g., single gate, dual gate)
- Auto-close delay
- Safety sensor activation
- Force settings
4.3 Learning Procedure
After all connections are made and DIP switches are set, the system typically requires a learning procedure to set gate travel limits and program remote controls.
- Gate Limits: Use the "Learn" button in conjunction with the "Inc/Start" and "Dec/Smart" buttons to teach the board the open and close positions of the gate(s). Follow the specific sequence outlined in your gate opener's main manual.
- Remote Controls: Press the "Learn" button briefly, then press a button on your remote control to pair it with the system. The LED display or a specific LED will usually indicate successful pairing.
5. Operating Instructions
5.1 Basic Operation
Once configured, the gate opener can be operated via remote control or wired input devices (e.g., push button, keypad). A single press of a programmed remote button typically initiates an open/close cycle. Another press during operation may stop or reverse the gate, depending on the programmed mode.
5.2 LED Display and Status Indicators
The "8.8." LED display provides feedback on the board's status, programming steps, and error codes. The "Smart", "State", "Rf", and "Charge" LEDs also indicate various operational conditions:
- Smart LED: Indicates smart functions or advanced features are active.
- State LED: Shows the current operational state (e.g., idle, opening, closing).
- Rf LED: Illuminates when an RF signal (from a remote control) is received.
- Charge LED: Indicates the backup battery is charging.
6. Maintenance
Regular maintenance ensures the longevity and reliable operation of your JUJIANG EGA-15 control board and the entire gate opener system.
- Visual Inspection: Periodically inspect the control board for any signs of damage, loose connections, or corrosion. Ensure the enclosure is sealed to protect against environmental elements.
- Wiring Check: Verify that all wiring connections are secure and free from wear or damage.
- Battery Check: If a backup battery is installed, check its charge status and condition regularly. Replace if necessary.
- Cleanliness: Keep the control board and its enclosure clean and free from dust, debris, and insects.
For maintenance of the gate opener mechanism itself, refer to the specific instructions provided with your gate opener system.
7. Troubleshooting
If you encounter issues with your JUJIANG EGA-15 control board, consult the following troubleshooting guide. For complex problems, contact a qualified technician.
- Gate Not Responding:
- Check main power supply (24V AC) and ensure the power switch on the board is ON.
- Verify remote control battery and ensure it is properly paired (check Rf LED).
- Inspect all wiring connections to motors and input devices.
- Check for any obstructions in the gate's path that might trigger safety sensors.
- Gate Stops Mid-Cycle:
- Check for obstructions.
- Review DIP switch settings for force limits or auto-reverse sensitivity.
- Ensure motor connections are secure.
- LED Display Shows Error Code:
- Refer to the specific error code list in your gate opener's main manual for detailed explanations and solutions. Common errors might relate to motor overload, sensor faults, or limit switch issues.
- Battery Not Charging:
- Verify the battery is correctly connected to the BAT+ terminal with correct polarity.
- Check the battery itself for faults.
- Ensure the main 24V AC power supply is active.
