Decreases parameter values during configuration. 4. Parameter Settings and Programming Mode

After a fault clears, the relay will wait for a user‑set recovery delay before reconnecting the load (default 30 s). This helps avoid rapid on‑off cycling when the power supply is fluctuating.

Verify that the incoming line is wired to the top IN ports and not the bottom OUT ports. Check the primary circuit breaker to confirm power is flowing to the device. 4. Over-current tripping during heavy appliance usage Cause: Total load exceeds the A8 threshold setting. tomzn tovpd1-60-ec manual

The installation of the Tomzn TOVPD1-60-EC should be performed by a qualified electrician to ensure safety and compliance with local electrical codes. It is typically installed at the point of entry of the electrical supply into a building or in a distribution panel. This strategic placement allows it to protect all downstream electrical devices.

The LCD shows the present voltage and current simultaneously. A backlight makes the display readable even in dark electrical cabinets. Decreases parameter values during configuration

1A to 63A (Adjustable, default set to 40A or 63A depending on sub-model)

The grid voltage exceeds your high limit setting, or the limit is set too low. This helps avoid rapid on‑off cycling when the

The display shifts to the under-voltage threshold symbol (often indicated by a low voltage value like 170 ). Use or ▼ to adjust the lower limit. Press SET to save and move to the next option. 3. Over-Current Protection Value
