As shown in the figures above, the reason of the appearance of F7862,
according to the user manual of G120XA, is that the input signal of the
signal source r402.1 of external fault 3 is low, and the state of r4022.0~3 is
controlled by X9 terminal. Therefore, when F7862 fault occurs, it is
necessary to confirm whether X9 terminal has been correctly connected!
