Warnings and fault strings
Additionally, different strings, as shown in
Table 10 display with a particular warning or fault.
Only one normal operating string or fault string
is presented at a time. However, if several
warnings happen at the same time, they display
on the LCD alternately. In this case, the normal
operating mode string and the warning string
will be shown alternately. Once a fault occurs,
all previous warnings will not be shown again;
only the fault string will be presented.
