Alarm Status Page
Figure 11 shows a typical alarm page for JUNIOR. It displays the current status of the alarms for up to four
temperature sensors and three fans

. When an alarm is active the text indicates the condition, and is highlighted in
red. The latched alarms for shutdown and fault are indicated separately. A latched fault indicates an internal fault
has occurred and the unit should be power cycled to clear it.
The alarms are updated once every second and clear automatically when the alarm condition clears except the
shutdown or fault which have to be cleared either by switching the control mode to off or power cycling the unit.
