Working mode description

Introduction to the Flashing and Breaking Function

Manual mode: For each operation of the relay, the relay will flip once (open when closed, close when open);

Flashing mode: For each operation of the relay, the relay will close for 1 second (actual time =set number * 0.1) and then automatically disconnect;

Flashing mode: For each operation of the relay, the relay will disconnect for 1 second (adjustable time) and then automatically close;
