TM Treadmill controller

Question:

I´m trying to repair a board TM5942. I see it uses a transformer with 2 secondaries, I guess they should be around 12Vac, could you check the value of this transformer?

I also see on the connector for panel one signal is coming and another signal is going so the only way is control speed demand is coming to the board but I don´t know which signal is sending the board to the panel.

I see the processor should switch on the relay but I don´t know when because we have only one opto to send a signal from the panel to the MCB.

I see 4 LED:
LVS = ???
RLY = Relay
PANEL = Power to the panel
CONNECT = ???

Can you help me to clear a little bit the philosphy under this board? Thanks, regards,


Answer

it's a tx/rx controller which speaks to the console, this is the reason why it's written connect. I don't have much experience on those TM boards as they are not very common.
If you don't have a console to test it, repair is very difficult. In this case I think it's better to give a new controller to the customer. You risk loosing time to understand how it works and then you learn just for a few pcs in your life.

    1. You should replace the controller. You can buy it here: https://www.partsfortreadmill.com/catalogsearch/result/?q=5942 please be careful because they look similar but there are two versions one has 2 pin speed sensor, and another 3 pin speed sensor.

  3. Hello,
    1. Check DC motor, connect battery to motor red +, black -. If motor good next step check the board TM5942.
    2. CHECK LEDS on board TM5942:
    LVS = on - when power switch on;
    RLY = Relay on when pushbutton on conrlol panel on;
    PANEL = Power to the panel - on - when power switch on;
    CONNECT = blinks when pushbutton on conrlol panel on;

  4. 3. Check the resitors 2 mom o.5 watt, 4 ea on board, often faulty.
    4. Check power supply voltage 12v and 5 volt.
    5. Сheck short circuit of main IGBT transistor and diode.
    6. Check voltage 340 volt on big capacitor.
