28 Fault Indication and Fault Finding
28.1 Fault Indication
When the system has no faults present, the VAR8 displays the current time and date on the LCD display,
and indicates that the system is healthy.
If a fault occurs, then the unit displays text describing the fault. A display of the fault is alternated with a
display of the current date and time. In the event of multiple faults each fault is displayed in sequence, while
alternating with the date and time display. Faults are time and date stamped as they occur and added to the
fault log.

pressing the front panel FAULT CLEAR key, or through the user interface’s ‘Faults’ menu. If a fault cleared in
