Alarms and Errors
Several conditions can cause alarms in the XTR. Some conditions are:
• From user configurable features.
• Controlled in hardware and will trigger regardless of configuration.
All alarms, with the exception of the Fan alarm, will result in the output of
the power supply being disabled. The Fan alarm does not affect the output.
When an alarm is triggered, the appropriate alarm message will begin
blinking on the display and the Alarm LED will be illuminated.It is
possible that more than one alarm will trigger at the same time. When this
occurs, the alarm with the highest precedence will blink on the display.
Table 3-4 lists the precedence of alarms. If the alarm is cleared and the
event which caused the alarm has not been corrected, then the alarm may
trigger again immediately. Fix the reason for the alarm before you clear it.
