Illuminates when a threshold is breached and the device trips. Programming and Parameter Settings

The Tomzn TOVPD1-60-EC surge protector is a valuable component in any electrical system, providing essential protection against surges and enhancing the reliability of connected devices. Its robust design, combined with compliance with relevant standards, makes it a suitable choice for a wide range of applications. Proper installation, maintenance, and monitoring are key to maximizing its protective benefits.

Range 230V–300V or OFF (Default: 270V).

Before modifying any settings, ensure your system aligns with the hardware limits of the device: 230VAC (50Hz / 60Hz) tomzn tovpd1-60-ec manual

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.

Dedicated light-emitting diodes indicate whether a trip was caused by an Over-voltage (U>), Under-voltage (U<), or Over-current (I>) event.

The grid voltage exceeds your high limit setting, or the limit is set too low. Illuminates when a threshold is breached and the

Check your A5 (Current) setting. If you are running a kettle and a heater simultaneously, you may need to increase the Amperage limit (provided your wiring can handle it).

: Allows users to check the reason for the last trip by holding the "UP" button for over 12 seconds. Power-on Delay

If the displayed voltage differs from a known accurate meter, the device allows ±10 % adjustment. Enter the calibration mode (parameter A13) and fine‑tune the reading using the UP/DOWN buttons. Proper installation, maintenance, and monitoring are key to

After installation:

Initiates parameter configuration mode and cycles through the menu options.

The duration the under-voltage must persist before the device executes a trip. Over-current Trip Threshold 1A – 63A

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