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 5-23 for detailed descriptions.
