5.2 Installation Steps

1. Power Disconnection: Before beginning installation, ensure that the main power supply to the circuit is completely disconnected.
2. Mounting: Mount the TVPS3 protector securely on a DIN rail within an appropriate electrical enclosure.
3. Wiring: Connect the incoming N (Neutral) and L (Live) lines to the 'IN' terminals as indicated in the wiring diagram. Connect the outgoing N and L lines to the 'OUT' terminals. Ensure correct phase connections (L1, L2, L3).
4. Verification: Double-check all wiring connections for tightness and correctness.
5. Power Restoration: Once wiring is complete and verified, restore power to the circuit. The device display should illuminate.

6. Operating Instructions

6.1 Display and Indicators

The TVPS3 features a clear digital display and indicator lights to show operational status and protection events.

• Digital Display: Shows real-time voltage (V) and current (A) for each phase (L1, L2, L3).
• Manual Switch (Power Button): Toggles the output relay.
• Menu Key (M): Used to enter and navigate the settings menu.
• Adjustment Keys (Up/Down Arrows): Used to adjust parameter values.
• Output Indication: Indicates if the output relay is closed.
• >U (Over-Voltage Indication): Lights up when an over-voltage condition is detected.
• <U (Under-Voltage Indication): Lights up when an under-voltage condition is detected.
• >I (Over-Current Indication): Lights up when an over-current condition is detected.
• SYN (Asymmetry Fault Indication): Indicates an asymmetry fault in Synchronous mode.
• ASY (Asymmetry Fault Indication): Indicates an asymmetry fault in Asynchronous mode.

6.2 Mode Selection (SYN/ASYNC)

The TVPS3 supports two distinct operating modes:

• Synchronous Mode (SYN): In this mode, the three-phase relays operate simultaneously. If a protection event occurs on any phase, all three phases will be disconnected. This mode is suitable for protecting equipment that requires all phases to be present and balanced.
• Asynchronous Mode (ASY): In this mode, each phase relay operates independently. If a protection event occurs on a specific phase, only that phase will be disconnected, while the other phases continue to operate. This mode is useful for systems where individual phase protection is desired.

6.3 Parameter Settings

To adjust protection parameters, press the 'M' (Menu) key to enter the settings menu. Use the Up/Down arrow keys to navigate through parameters and adjust values. Press 'M' again to confirm and save settings.

Figure 6: Table detailing the technical parameters, setting ranges, factory default values, and function descriptions for the TVPS3 protector.

Key adjustable parameters include:

• Power-on delay time: Time before power is restored after a power recovery.
• Over-voltage protection value: Upper voltage limit.
• Over-voltage recovery value: Voltage at which the protector automatically resets after an over-voltage event.
• Over-voltage protection delay time: Delay before protection activates for over-voltage.
• Under-voltage protection value: Lower voltage limit.
• Under-voltage recovery value: Voltage at which the protector automatically resets after an under-voltage event.
• Under-voltage protection delay time: Delay before protection activates for under-voltage.
• Three phase voltage error value: Threshold for voltage unbalance.
• Three phase voltage unbalance protection value: Voltage difference threshold for unbalance protection.
• Three phase voltage unbalance recovery value: Voltage difference at which the protector resets after unbalance.
• Phase sequence protection switch: Enable/disable phase sequence protection.
• Over-current protection value: Upper current limit.
• Over-current recovery delay time: Delay before reset after over-current.
• Over-current protection action time: Delay before protection activates for over-current.
• Three phase current error value: Threshold for current unbalance.
• Times of continuous over current protection: Number of times over-current protection can trip before permanent lockout.
• Phase-loss protection: Enable/disable phase loss protection.

6.4 Protection Functions

The TVPS3 provides comprehensive protection against various electrical faults:

• Over/Under Voltage Protection: Disconnects power if voltage exceeds or falls below set thresholds.
• Over-Current Protection: Disconnects power if current exceeds the set limit.
• Voltage Unbalance Protection (Asymmetry Protect): Detects and protects against significant voltage differences between phases.
• Phase Sequence Protection: Ensures the correct order of phases (L1, L2, L3) to prevent damage to phase-sensitive motors and equipment.
• Phase Loss Protection: Disconnects power if one or more phases are lost.

Note: When operating in ASY (Asynchronous) mode, phase sequence and voltage unbalance protection features are not active as the device treats each phase independently.

7. Maintenance

The XPR3SS Taxnele TVPS3 is designed for minimal maintenance. However, periodic checks can ensure optimal performance and longevity.

• Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
• Connection Checks: Periodically inspect wiring connections to ensure they remain tight and free from corrosion.
• Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges.

8. Troubleshooting

If you encounter issues with your TVPS3 protector, refer to the following common troubleshooting steps:

• Device Not Powering On:
  • Check the main power supply to the circuit.
  • Verify that the input wiring (N and L lines) is correctly connected and secure.
• Output Not Activating:
  • Check the display for any active protection indicators (>U, <U, >I, SYN, ASY). Address the underlying power issue if a protection is active.
  • Ensure the 'Manual Switch' is in the ON position.
  • Verify that all protection parameters are set appropriately for your electrical system.
• Incorrect Voltage/Current Readings:
  • The device supports manual calibration. Refer to section 6.3 and the parameter table to calibrate if necessary.
  • Ensure proper wiring and secure connections.
• Frequent Tripping:
  • Review your set protection values (over-voltage, under-voltage, over-current, unbalance). They might be too sensitive for your application.
  • Investigate the electrical system for actual power fluctuations or overloads.

If the problem persists after following these steps, please contact customer support.
