: When illuminated, the digital screen is displaying the active current consumption in Amperes.

Just wired up my Tomzn TOVPD1-60-EC and couldn't find the manual right away. Here are the default settings and programming steps for anyone who needs them:

Even with a high-quality protective relay, unexpected behavior can occur. The TOVPD1-60-EC manual provides guidance for common issues:

The TOMZN TOVPD1-60-EC is a multi-functional protective relay designed to monitor single-phase, two-wire AC active energy systems. Its primary function is to safeguard electrical circuits and connected equipment by disconnecting the load when the voltage or current exceeds or falls below pre-set safety thresholds. Once the voltage or current returns to a permissible range, the relay automatically reconnects the circuit, ensuring continuous operation without manual intervention. tomzn tovpd1-60-ec manual

Press once to display the Overvoltage value. Use ← / → to adjust (230-300V or OFF).

Understanding the technical boundaries of your device ensures safe operation and prevents premature hardware failure. Specification TOVPD1-60-EC Rated Voltage 230V AC (50Hz / 60Hz) Rated Current Range 1A to 60A (Adjustable, Default: 40A) Over-voltage Protection Value Range 230V to 300V (Adjustable, Default: 270V) Under-voltage Protection Value Range 140V to 210V (Adjustable, Default: 170V) Power Consumption Electrical Machinery Life > 100,000 Cycles Installation 35mm DIN Rail Wiring and Installation Diagram

The TOVPD1-60-EC features a dual digital display. The default display mode alternates between voltage (in Volts) and current (in Amps) or may show voltage and current simultaneously depending on the specific version. Under normal conditions, the device displays the present line voltage and current of the load. If a protection condition is triggered, the display will typically flash and show the fault parameter. : When illuminated, the digital screen is displaying

Note: Never reverse the Input (IN) and Output (OUT) terminals, as this will damage the internal relay and voltage sensing circuitry. 3. Display Interface and Button Functions

The is a digital, dual-display, adjustable over-voltage, under-voltage, and over-current protection relay designed for standard 35mm DIN rail installation. Acting as an intelligent gatekeeper for electrical systems, this device continuously monitors grid health and cuts off power instantaneously during volatile fluctuations to protect sensitive appliances. The TOVPD1-60-EC manual provides guidance for common issues:

Sets a limit on how many consecutive times the device will reset during persistent faults before locking out. Troubleshooting and Operational Codes

Completely disconnect the main incoming utility power feed. Verify lines are electrically dead using a verified digital multimeter.

For up‑to‑date information, software updates (if any), and the latest version of the TOVPD1‑60‑EC manual, always refer to the official TOMZN website or contact their technical support team.

Always double-check terminal torque specifications and ensure wires are securely fastened to prevent overheating.
