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.
No Fault
When a fault is detected the front panel 'fault' LED
flashes and the built-in loudspeaker emits an alarm tone.
28.2

Fault Acceptance

The 'fault' LED may be steadied and the loudspeaker may be muted by pressing the front panel FAULT
ACCEPT key, or through the user interface's Faults menu.
FAULT
Press to silence the Sounder and
ACCEPT
steady the LED.
Newly occurring faults cause the sounder to resume sounding, and the 'fault' LED to resume flashing.
28.3

Fault Clearance

Once a fault is physically fixed it is still latched on the LCD display. It is removed from the latched display by
pressing the front panel FAULT CLEAR key, or through the user interface's 'Faults' menu. If a fault cleared in
this way still persists, then the fault warning condition will be restored within 100 seconds.
FAULT
Press to clear the fault.
CLEAR
Pressing the FAULT CLEAR button, or selecting the user interface's 'Faults→Clear' menu option, releases
any active amplifier standby switching to reset the system to a known state.
