• Always disconnect power before installing or servicing the ATS.
• Maak seker dat alle bedrading voldoen aan plaaslike en nasionale elektriese kodes.
• Verifieer korrekte voltage and current ratings before connecting the device.
• Moenie die toestel gebruik as dit beskadig lyk nie.
• Hou kinders weg van elektriese toerusting.

3. Produk verbyview

The EARU Electric 3-Phase ATS is an intelligent device that continuously monitors your three-phase power supply. It automatically switches single-phase loads to a healthy phase in case of a phase failure or imbalance, ensuring continuous operation of critical equipment.

3.1. Pakketinhoud

• 1 x EARU Electric 3-Phase Auto Transfer Switch (ATS)

3.2. Front Panel and Indicators

Prentbeskrywing: The front panel of the ATS features a digital display showing voltage for L1, L2, L3 phases and current for L1. Below the display are indicators for Power, Over-voltage (>V), Under-voltage (<V), and Over-current (>I). Control buttons include 'SET' (Menu key), 'Digit+/Up', 'Digit-/Down', and 'Manual ON/OFF' (Power button).

The digital display provides real-time voltage readings for each phase (L1, L2, L3) and the current for L1. Status indicators alert you to the operational state and any detected faults:

• Krag: Output indication.
• >V: Oorvoltage aanduiding.
• <V: Onder-voltage aanduiding.
• > ek: Over-current indication.

Control buttons allow for parameter settings and manual operation:

• STEL: Menu key for accessing settings.
• Digit+/Up: Increases value or navigates up in menus.
• Digit-/Down: Decreases value or navigates down in menus.
• Handleiding AAN/UIT: Power button for manual control.

4. Opstelling en installering

The ATS is designed for standard DIN rail mounting. Ensure sufficient space for ventilation and wiring connections.

4.1. Bedradingsdiagram

Prentbeskrywing: A detailed wiring diagram illustrates the connection points for the ATS. The top terminals are labeled 'IN' with connections for N, L1, L2, L3. The bottom terminals are labeled 'OUT' with connections for N and L1. The diagram shows how to connect the three-phase input to the ATS and how a single-phase load (L1 and N) is connected to the output, with internal connections for phase monitoring and switching.

Follow the wiring diagram carefully. Incorrect wiring can lead to device malfunction or electrical hazards.

• Connect the incoming three-phase power supply (N, L1, L2, L3) to the 'IN' terminals.
• Connect the single-phase load (N, L1) to the 'OUT' terminals. The ATS will manage the phase transfer for the L1 output.
• Ensure all connections are secure and tightened to prevent loose contacts and overheating.

4.2. Aanvanklike aanskakeling

After completing the wiring, restore power to the system. The ATS will power on and begin monitoring the phases. The digital display will show the current voltage readings for each phase. If all phases are stable and within acceptable limits, the ATS will provide power to the output.

5. Bedryfsinstruksies

The ATS operates automatically, but you can adjust its protection parameters to suit your specific requirements.

5.1. Understanding the Display and Indicators

The digital display continuously shows the real-time voltage of each phase (L1, L2, L3) and the current on L1. The indicator lights provide quick visual feedback on the device's status and any detected anomalies.

Prentbeskrywing: ’n Nabyskoot view of the ATS digital display. It shows '220V' for L1, L2, and L3, and '63.0A' for L1 current. Below these readings are small indicator icons for Power, >V (Over-voltage), <V (Under-voltage), and >I (Over-current).

5.2. Adjusting Protection Parameters

Use the 'SET' button to enter the parameter setting mode. Use the 'Digit+/Up' and 'Digit-/Down' buttons to navigate through settings and adjust values. Press 'SET' again to confirm and save changes.

5.3. Automatic Phase Transfer

The ATS automatically monitors the three input phases (L1, L2, L3). If a phase failure or significant voltage imbalance (over/under voltage) is detected on the currently supplying phase, the device will automatically transfer the single-phase output load to a healthy, stable phase within the same supply. This process is designed to be seamless and rapid, minimizing power interruption to connected equipment.

5.4. Automatic Recovery

Once the primary phase recovers and stabilizes, the ATS will intelligently switch the load back to the primary source, ensuring optimal power distribution and preventing equipment damage from unstable power. The recovery delay can be configured as per your operational needs.

6. Onderhoud

The EARU Electric ATS is designed for minimal maintenance. However, periodic checks are recommended to ensure optimal performance and longevity.

• Skoonmaak: Hou die toestel skoon en vry van stof en puin. Gebruik 'n droë, sagte lap vir skoonmaak. Moenie vloeibare skoonmaakmiddels gebruik nie.
• Verbindingskontroles: Periodically inspect all wiring connections to ensure they remain tight and free from corrosion.
• Omgewingstoestande: Verseker dat die bedryfsomgewing binne die gespesifiseerde temperatuur- en humiditeitsreekse bly.
