3.1. Packungsinhalt
- 1 x EARU Electric 3-Phase Auto Transfer Switch (ATS)
3.2. Frontplatte und Anzeigen
Bildbeschreibung: 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:
- Leistung: Output indication.
- >V: Überlautstärketage-Anzeige.
- <V: Untervolumentage-Anzeige.
- >ICH: Over-current indication.
Control buttons allow for parameter settings and manual operation:
- EINSTELLEN: Menu key for accessing settings.
- Digit+/Up: Increases value or navigates up in menus.
- Digit-/Down: Decreases value or navigates down in menus.
- Manuell EIN/AUS: Power button for manual control.
4. Einrichtung und Installation
The ATS is designed for standard DIN rail mounting. Ensure sufficient space for ventilation and wiring connections.
4.1. Schaltplan
Bildbeschreibung: 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. Erste Inbetriebnahme
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. Bedienungsanleitung
The ATS operates automatically, but you can adjust its protection parameters to suit your specific requirements.
5.1. Die Anzeige und die Indikatoren verstehen
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.
Bildbeschreibung: Eine Nahaufnahme 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. Wartung
The EARU Electric ATS is designed for minimal maintenance. However, periodic checks are recommended to ensure optimal performance and longevity.
- Reinigung: Halten Sie das Gerät sauber und frei von Staub und Schmutz. Verwenden Sie zum Reinigen ein trockenes, weiches Tuch. Verwenden Sie keine flüssigen Reinigungsmittel.
- Verbindungsprüfungen: Überprüfen Sie regelmäßig alle Drahtverbindungen, um sicherzustellen, dass sie fest sitzen und frei von Korrosion sind.
- Umgebungsbedingungen: Stellen Sie sicher, dass die Betriebsumgebung innerhalb der vorgegebenen Temperatur- und Feuchtigkeitsbereiche bleibt.
7. Fehlerbehebung
Sollten Sie Probleme mit Ihrem Bewerbermanagementsystem (ATS) haben, beachten Sie bitte die folgenden häufig auftretenden Probleme und Lösungen:
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Keine Leistungsabgabe | No input power; all phases unstable; device in fault state. | Check incoming power supply. Verify all phases are stable. Check fault indicators. |
| ">V" or "<V" indicator lit | Überlautstärketage oder Unterlautstärketage detected on a phase. | Eingangslautstärke prüfentage stability. The ATS will automatically transfer if another phase is healthy. |
| ">I" indicator lit | Over-current detected on the output. | Reduce load on the output. Check for short circuits in the connected equipment. |
| Device not transferring phases | No healthy alternative phase available; transfer delay setting too long. | Ensure at least one healthy phase is present. Check and adjust the transfer delay settings. |
| Digitalanzeige funktioniert nicht | No power to the device; internal fault. | Check power supply. If power is present and display is off, contact support. |
