3.2. Front Panel and Indicators
تصویر کی تفصیل: 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:
- طاقت: Output indication.
- >V: زیادہ جلدtagای اشارہ.
- <V: زیر جلدtagای اشارہ.
- >میں: Over-current indication.
Control buttons allow for parameter settings and manual operation:
- سیٹ: Menu key for accessing settings.
- Digit+/Up: Increases value or navigates up in menus.
- Digit-/Down: Decreases value or navigates down in menus.
- دستی آن/آف: Power button for manual control.
4. سیٹ اپ اور انسٹالیشن
The ATS is designed for standard DIN rail mounting. Ensure sufficient space for ventilation and wiring connections.
4.1. وائرنگ ڈایاگرام
تصویر کی تفصیل: 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 ابتدائی پاور اپ
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. آپریٹنگ ہدایات
The ATS operates automatically, but you can adjust its protection parameters to suit your specific requirements.
5.1. ڈسپلے اور اشارے کو سمجھنا
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.
تصویر کی تفصیل: ایک قریبی اپ 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 دیکھ بھال
The EARU Electric ATS is designed for minimal maintenance. However, periodic checks are recommended to ensure optimal performance and longevity.
- صفائی: Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- کنکشن چیکس: وقتاً فوقتاً تمام وائرنگ کنکشن کا معائنہ کریں تاکہ یہ یقینی بنایا جا سکے کہ وہ سخت اور سنکنرن سے پاک ہیں۔
- ماحولیاتی حالات: یقینی بنائیں کہ آپریٹنگ ماحول مخصوص درجہ حرارت اور نمی کی حدود کے اندر رہتا ہے۔
