1. Function description
Flash close: when the relay is in the off state, operate the relay to close for a period of time (setting parameter * 0.1s) and then automatically disconnect;
Flash off: when the relay is in the closed state, the operating relay will close automatically after being disconnected for a period of time (setting parameter * 0.1s);
2. The flash on and flash off function is realized by sending instructions, and the mode cannot be set by using dam debugging software.
3. Instruction description
① Support to control the delay action of one channel separately;
② It supports the delay action of controlling multiple channels with different delay time at one time. When controlling multi-channel delay action, the channels must be continuous.
③ Detailed explanation of single channel flash on / off instruction
