Instrument Problem Alarms - Welch Allyn Atlas Operator's Manual

3.3 Instrument Problem Alarms

Instrument Problem Alarms, although they rarely occur, are of three types: 1) the Atlas Monitor detected
an internal fault during power-on self test; 2) the Atlas Monitor detected an internal fault during use; 3)
the Atlas Monitor reports that it lost power while in use the last time it was operating. Instrument
Problem Alarms do not trigger a Print On Alarm.
You will rarely see an Instrument Problem Alarm.
These alarms indicate the failure of some internal
circuitry. The Atlas Monitor performs a Self-
Check when it is turned on. If it finds something
that does not respond correctly to the tests, an
Instrument Problem Alarm will be reported.
Problems detected at power-on will produce an
error message telling you what is wrong, but will
not sound an alarm. Also, the affected
measurement indicator will be blank. Problems
detected during use will produce an error message
and sound the Instrument Problem Alarm.
When a problem is detected by the Self-Check,
the rest of the instrument may not be affected, so
in most cases, you can use the monitor for the
other measurements. (Be sure to contact the
Welch Allyn Technical Service Department).
Silencing alarms – The audible alarm for
instrument problems has a distinctly different
sound from Patient Alarms and from
Measurement Invalid Alarms. Press the
button to silence this alarm for a short period. This
will not erase the message. Press the appropriate
button to prevent this alarm from
ALARMS Off
sounding the audible alarm again and to remove
the error message.
Note: If the Atlas Monitor is set the "Francais"
language in the Advanced Configuration
Menu, the
ALARMS Off
suspend the alarm for 3 minutes.
Power failure – If the AC power to the Atlas
Monitor model 621xx is interrupted when the
monitor is in use, either because of a power failure
or because the AC cord was pulled out without
turning off the Atlas Monitor first, an alarm will
Silence
buttons will only
occur when the system is plugged in and turned
back on.
A message will appear reporting that the power
was interrupted and settings were lost. The Atlas
Monitor may not remember changes that you
made to alarm limits and Advanced Configuration
menu entries during the last session. You should
review your settings to ensure that you have the
proper values set.
The alarm and error message will clear when you
press any button on the Atlas Monitor.
The power failure alarm should not occur on Atlas
Monitor models 622xx and 623xx because the
built-in battery will keep the system running
during a power failure or power cord being pulled
out.
