    Buenos días, tengo problemas al arrancar la máquina. Al encenderla, todo funciona perfectamente y no marca ningún error. Al arrancarla o arrancarla, gira 10 grados y el motor se para, lo que indica un error. La reinicio y sigue así durante dos horas, luego funciona correctamente todo el día. Adjunto imágenes de las pantallas al arrancar con el error.

    Hello Adil
    No, the machine has been installed and working for 10 years.
    The problem started with minutes of time with failure, now it's 2 hours, until it starts.
