5.7.5 DIAGNOSTICS

The DIAGNOSTICS menu is classified into two groups. After entering the menu, pressing the up button and
down button can switch between two groups and pressing the enter button can enter the parameters of the
corresponding group. The parameters of group 1 are settable and used to help the maintenance personnel
start and cut off devices by hand in site, so as to realize the diagnosis for devices. The parameters of group 2
are read only and reflect the fault condition of the devices. See Table 5-22 for detailed descriptions.
