5. Setup u Installazzjoni

Informazzjoni Importanti dwar is-Sigurtà: Installation should only be performed by qualified personnel. Ensure all power sources are disconnected before beginning installation. Use copper conductors only. Refer to the full installation instructions for specific torque values for terminal connections.

5.1 Immuntar

• The AC03 controller is designed for use on a flat surface of a Type 1 enclosure.
• Ensure the mounting location allows for adequate ventilation and does not exceed the maximum ambient temperature of 70°C.

5.2 Konnessjonijiet tal-Wiring

Refer to the diagram below for terminal identification and connection points. Ensure all connections are secure and correctly polarized.

Figura 5.1: Wara view of the AC03 controller showing wiring terminals.

Power Supply (9-30 VDC)

• Connect the DC power supply (9-30 VDC) to the designated POWER terminals. Observe polarity. The maximum current draw is 0.4A.

Voltage Sensing

• Mains Voltage: Connect the mains power lines (L1, L2, L3, N) to the MAINS VOLTAGE terminals. The controller supports 3x277A(480A)/VAC.
• Ġeneratur Voltage: Connect the generator output lines (L1, L2, L3, N) to the GENERATOR VOLTAGE terminals. The controller supports 3x277A(480A)/VAC.

Sensing Kurrent

• Connect the current transformers (CTs) for generator current measurement to the GENERATOR CURRENT (0-5A) terminals.

Inputs u Outputs

• Binary Inputs (B1-B7): Connect external switches or sensors for various control functions.
• Analog Inputs (A11-A13): Connect analog sensors for parameters like fuel level, oil pressure, etc.
• RPM Input: Connect the engine RPM sensor to the RPM IN terminal.
• Binary Outputs (B01-B07): These outputs can be configured to control external devices such as contactors, alarms, or engine start/stop relays.

Komunikazzjoni

• JISTA ': Connect to a CAN bus for communication with other compatible devices.
• COM: General communication port.

6. Operazzjoni

The AC03 controller features a clear LCD display and a set of intuitive buttons for operation. The front panel includes indicators and a simplified diagram of the power system (mains and generator).

6.1 Kontrolli ta' Front Panel

• Display LCD: Shows real-time data, alarms, and menu options.
• MODE Buttons (Left/Right Arrows): Used to navigate through different display screens or menu options.
• PAGE Buttons (Up/Down Arrows): Used to scroll through parameters or adjust settings within a menu.
• START Button (Green): Initiates the generator start sequence.
• Buttuna STOP (Ħamra): Initiates the generator stop sequence.
• FUEL PUMP Button: Manually controls the fuel pump (functionality may vary based on configuration).
• FAULT RESET Button: Clears active fault alarms after the issue has been resolved.
• CR / CG Buttons: Typically used for Mains (CR) and Generator (CG) control, often related to breaker operation or status indication.

6.2 Sekwenza ta' Operazzjoni Bażika

1. Qawwa Mixgħul: Ensure the DC power supply (9-30 VDC) is connected and active. The LCD display should illuminate.
2. Monitoraġġ: Use the MODE and PAGE buttons to view various generator and mains parameters (voltage, current, frequency, engine RPM, oil pressure, temperature, etc.).
3. Bidu Manwali: Press the green START button to manually initiate the generator start sequence. The controller will follow its programmed startup routine.
4. Waqfien manwali: Press the red STOP button to manually shut down the generator.
5. Immaniġġjar tal-Ħsara: If a fault occurs, an alarm will be displayed on the LCD. Identify and resolve the fault condition, then press the FAULT RESET button to clear the alarm.
6. ATS Operation: In automatic mode, the controller will monitor the mains supply. If the mains fail, it will automatically start the generator and transfer the load. Upon mains return, it will transfer the load back and shut down the generator.

7. Manutenzjoni

Regular maintenance ensures the longevity and reliable operation of your AC03 controller.

• Tindif: Keep the controller's front panel clean and free from dust and debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
