    Hello, I am a student using the Ecotron EF22297B01 FCU to control a fuel cell. I just started working with this FCU and want to power it on, but when I apply 12V power to it and give the key-switch a threshold Voltage of >9V it starts drawing 3W (0.250Amps)for 2 seconds, drops to 0,6W (0.050Amps) for 3 seconds and then shuts off (0.000Amps). Does anyone know what is going on?

    Hi there,

    Happy to help, could you please send me how you connect your wires for powering up? That’s usually the first step we need to confirm.
