Always shut off the main power supply before beginning the physical installation.
The duration the current overload must persist before the device executes a trip. Fault Recovery Delay Time 1s – 500s
Press and hold the button for 3 seconds. The screen will flash, displaying the first parameter code ( A1 ). Parameter Configuration Table Parameter Function Adjustable Range Factory Default A1 Power-on delay time (Boot time) 1s – 500s A2 Over-voltage protection value 230V – 300V (or OFF) A3 Over-voltage recovery value 225V – 295V A4 Over-voltage protection action time 0.1s – 30s A5 Under-voltage protection value 140V – 210V (or OFF) A6 Under-voltage recovery value 145V – 215V A7 Under-voltage protection action time 0.1s – 30s A8 Over-current protection value 1A – 63A (or OFF) A9 Over-current protection action time 0.1s – 30s A10 Fault recovery delay time 1s – 500s A11 Continuously over-current fault times 1 – 20 times (or OFF) Saving Settings tomzn tovpd1-60-ec manual
Some TOVPD1-60-EC have two small potentiometers:
Many users fail to connect the top Neutral. The device needs the Neutral to power its internal processor and LCD screen. If you only connect the Live wire, the screen will remain blank. Always shut off the main power supply before
This occurs if your recovery voltage values ( P2 or P4 ) are set too close to the actual grid fluctuations. Widen the gap between the protection threshold and the recovery threshold.
I can then calculate the exact parameters you should program into the device. Share public link The screen will flash, displaying the first parameter
Check if the recovery timer is active. If an over-current fault occurred, reduce the load on your electrical panel before manually resetting or allowing the auto-reset timer to clear. 3. Frequent tripping on Over-voltage or Under-voltage
