Problem with starting 220AC
Publié : dim. avr. 05, 2020 5:18 pm
First of all, sorry for writing in English, my French is non-existent. (I am Russian living in NL)
But, according to my experience, this forum is the most competent place regarding Husqvarna automowers on the internet.
So, I tried to put my 220AC to work after winter, and found an issue. It starts, but then hangs on pin-code screen, sometimes I can press first ket from pin-code, but not more, it hangs. If I am not fast enough, I can't enter even single digit. And another symptom is that beeper produce high-frequency signal painful for ears. Close to ultrasound range. At the same time, it reacts on hatch close micro-switch and changes between "Enter pin-code" screen, to very bleak and flashing "Pin code expired" screen. Looks like this one goes on/off all the time.
Does anyone have idea what it could be? I presume MCU is OK, but then what else? If it known problem with known solution? Just in case, I am good enough with soldering, lets put it this way
