Value corresponding to the error is transmitted (see Table 24, Table 25). When the number of errors being detected is
under the maximum number, the value of parameter that is larger than the number of errors being detected is set to FF

Example:
In case of Disturbance X_H detection at
Pump running time = 5,000 minutes, control unit running time = 6,000 minutes
