Audible Alarm
3.3. Audible
Alarm
Different controller environmental and operational parameters (like
temperature, etc.) have been assigned a range of values between which they
can fluctuate. If either the upper or lower thresholds are exceeded, an
audible alarm will automatically be triggered. The alarm will also be
triggered when an active component on the GALAXY fails. If the
administrator is onsite and hears an alarm, the manager must read the error
message on the LCD screen or PC terminal to determine what has triggered
the alarm. After determining what has occurred, the manager must take
appropriate actions to rectify the problem.
WARNING!
If an alarm is triggered, it is necessary for you to determine the problem.
If the audible alarm is ignored and the problem is not rectified,
unexpected damages may occur.
3.3.1 Default Threshold Values
NOTE:
The threshold values listed below are used to trigger a warning event and
sound the alarm. A different value set is reserved for triggering the
cooling fans to operate at a high rotation speed. The fan speed value set
is not user-configurable.
Table 3-9
shows the default threshold values for the A16F-G2422. If any of
these values are surpassed, the alarm will sound:

The thresholds in
Table 3-9
are the default threshold values. To change
these pre-set values, please refer to the
User’s Operation Manual
that came
with your system. The values set for the subsystem’s ambient temperature
are pre-configured before shipping and cannot be changed.
