5 Fault Monitoring
The mode of operation is fully compliant with BS5839 Pt 8:1998 and BS EN54-2:1998 in the fault types that
are displayed and the mode of display.
Active faults, the system fault log, and the frame fault logs can be viewed on the LCD display. Active faults

In order to time-stamp the fault reports the VAR8 features a Real Time Clock (RTC). The unit is fitted with an
internal Lithium battery to keep this clock running when the power from the Router is turned off.
5.1 Indication, Acceptance, and Clearance
5.1.1 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.
