Product Function: (Long press the K3 button for about 2 seconds to enter the adjustment function)
P-1: Pulse Detection: The pulse relay is always closed within T time, and no pulse relay is disconnected after T time
P-2: Motor Stop Alarm: No detection when power on, the first pulse is detected, and the pulse relay has been disconnected within T time, otherwise the relay is closed
P-3: Pulse Trigger Reversal: Give a pulse signal, the relay state reverses
P-4: As long as a pulse signal is detected, the relay will be closed and kept closed until the module is powered off.
