3.1. Pakkens indhold
- 1 x EARU Electric 3-Phase Auto Transfer Switch (ATS)
3.2. Frontpanel og indikatorer
Billedbeskrivelse: 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), Undervolumentage (<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:
- Magt: Output indication.
- >V: Over-voltage indikation.
- <V: Under-voltage indikation.
- > jeg: Over-current indication.
Control buttons allow for parameter settings and manual operation:
- SÆT: Menu key for accessing settings.
- Digit+/Up: Increases value or navigates up in menus.
- Digit-/Down: Decreases value or navigates down in menus.
- Manuel ON/OFF: Power button for manual control.
4. Opsætning og installation
The ATS is designed for standard DIN rail mounting. Ensure sufficient space for ventilation and wiring connections.
4.1. Ledningsdiagram
Billedbeskrivelse: 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. Første opstart
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. Betjeningsvejledning
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.
Billedbeskrivelse: Et nærbillede 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. Justering af beskyttelsesparametre
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. Vedligeholdelse
The EARU Electric ATS is designed for minimal maintenance. However, periodic checks are recommended to ensure optimal performance and longevity.
- Rensning: Hold enheden ren og fri for støv og snavs. Brug en tør, blød klud til rengøring. Brug ikke flydende rengøringsmidler.
- Tilslutningstjek: Kontrollér regelmæssigt alle ledningsforbindelser for at sikre, at de forbliver tætte og fri for korrosion.
- Miljøforhold: Sørg for, at driftsmiljøet forbliver inden for de angivne temperatur- og luftfugtighedsområder.
7. Fejlfinding
If you encounter issues with your ATS, refer to the following common problems and solutions:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strømudgang | 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 | Over-voltage eller under-voltage detected on a phase. | Kontroller input voltage 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. |
| Digitalt display virker ikke | No power to the device; internal fault. | Check power supply. If power is present and display is off, contact support. |
For issues not covered here, please contact EARU customer support.
