Tomzn Tovpd1-60-ec Manual Jun 2026

Ensure that the load is turned on. If the load exceeds the limit set in P5 , the device will trip. Increase the P5 value if your household consumption safely permits it.

To adjust the over/under voltage trip points without the app, follow this manual procedure:

Check the input connections ( IN terminals) with a multimeter to verify that 230V AC power is actively reaching the device.

| Problem | Possible cause | Solution | |---------|----------------|----------| | Load always off, red LED solid | Voltage out of range (check with meter) | Wait for grid recovery or adjust setpoints | | Green LED off, no output | No input power / internal fuse blown | Check upstream breaker, replace device if dead | | Rapid on/off cycling | Loose neutral connection | Tighten N terminals at unit and mains | | Auto-reset never happens | Unit in permanent fault mode | Cycle mains power; if persists, replace unit | | Unit hot (>50°C) | Overload >60A or poor ventilation | Reduce load, increase air gap around DIN rail | tomzn tovpd1-60-ec manual

Check if the "A6" delay timer is still counting down. A small light or flashing digit usually indicates the recovery delay is active. Ensure that the load is turned on

Once the utility grid stabilizes within the recovery limits ( P2 and P4 ), the recovery timer ( P6 ) triggers. After the countdown completes, the device automatically reconnects power to your appliances. 6. Troubleshooting Common Issues
