Push Button Speaker Box with Built in FM Receiver - As presented at the Perth 2023 Mini

Hi, is anyone able to help me troubleshoot, I think I had it all working last night, everything was lit up, I haven't plugged it into the speakers yet but when I pushed the button the timer started going and the green lights on the relays turned on. I was trying to adjust the time but now it still appears to count up but on the relays the red lights are always on but the green lights are never on. The design is as per the last one on this page.
Anyway of testing if the relays are working or not with a multimeter?
The display has P1.1 on it, then OP, and then 04.6. It appears to count up to 4.6, stop and then just goes back to 00.0. Not sure if I wired it up and stuffed the relays or the setting changed.

I found programming the hardest bit to figure out. Not to much risk in damaging the relay if hooked up correctly.

The biggest indicator is if you hear the 'click' when the relay is triggered. If its not triggering, its likely not programmed correctly.

Have a look at these instructions to see if it helps

Programming

Operating modes:

• P1.1:signal is triggered again, invalid - Multiple pushes the button and it does nothing, ie timer from first push is length of activation
• P1.2:signal is triggered again, the clock is reset - Each button push resets the timer from the beginning (i like this option)
• P1.3 - P4 - Not used

Timing range

• 0.1 seconds (min) to 999 minutes (max) continuously adjustable
• How to choose the time range?
• After setting the mode selection screen parameter value by a short press "STOP" button to select the time range;
• XXX. decimal point in the unit place, time range: 1 second to 999 seconds.
  • 1. X a single dot point in second place, Timing range: 0.1 seconds to 99.9 seconds
  • 2. X. X. three dot point between all numbers, Timing range: 1 minute to 999 minutes.
• For example, you want to set Operational time to 3.2 seconds, then move the decimal point to decade place, the digital display 03.2.
  • Other examples.
    • 15 seconds 15.0 (1 dot)
    • 15 minutes 1.5.0. (3 dots)
    • 5 minutes 0.5.0. (3 dots)

Programming

• The module is powered up, the display at the current work mode (P1.1 default mode), then enter the main interface; press "SET" button for 2 seconds after release to enter mode selection interface; a short time by pressing "UP", "DOWN" key to select the mode (P1.1 ~ P-4).
• Select the mode (such as P3.2), short press the "SET" button, then the parameter to be set flashes ( "OP" on-time, "CL" off time, "LOP" cycles ( "---" represents infinite loop)), by "UP", "DOWN" keys to adjust the parameter value, support long press (rapid increase or decrease) and short press (increase or decrease one unit); then short press the "STOP" key to select the decimal point position, select the time range (0.1 seconds to 999 minutes); short press the "sET" button to set the next parameters of the current mode of procedure is as above.
• After the parameters are set, long press "SET" button for 2 seconds then release, the name of the current mode will flash once, and then return to the main screen, set the parameters of success!
• The main interface: In the relay does not work status display "000" (no decimal point), with a decimal point under relay state.
• Mode selection screen:Long press the "SET" key to enter, after setting is completed, long press the "SET" key to exit back to the main screen.

Great thanks for the guidance, I will keep playing tonight. Just to confirm, is it normal for the relays to have the red LED lit all the time, and then the green only when triggered?
Also, any idea how to reset the timer to default configuration? I couldn't find much from google.

For anyone reading this later and wondering, I managed to get it working again by changing it from mode 1.1 to 1.2. I actually prefer mode 1.2 (allows time to be restarted on button pressing) so I have left it.
