When the power is turned on, the trigger signal is received, the countdown starts, and the relay works. When the timer ends, the relay stops working, the time returns to the setting, and the next trigger signal is waited.

Instructions:

Press K1 to enter the time setting, the hundred digit digital tube starts to flash; press K2 at this time, the hundred digits change; press K1 again, the ten digital tube starts to flash; press K2 at this time, the ten digits change; press again After K1, the digital tube starts to flash. At this time, press K2, the digit of the digit changes; press K1 again to exit the setting, and the digital tube no longer flashes.
When the digital tube is normally displayed, press K2, the decimal point is shifted, the decimal point is 0 to 999 seconds in ones digit, the decimal point is 0 to 99.9 seconds in ten digits, and the decimal point is 0 to 999 minutes; the time is set.
