11.1 Alarm – Cause – Remedy
The Isolette 8000 plus displays alarm messages in the Trend/Alarm window. If two
or more system alarms occur simultaneously, or one after the other, the alarm
messages of the highest priority (i.e., Controller Failure alarms) are presented first.
They are followed by all other messages in sequence. A total of 6 messages can be
presented in the Trend/Alarm window.
In addition to a displayed message, alarm conditions are also indicated by an
acoustic alarm signal and a lighted LED.
In the following table, the alarm messages are listed in alphabetical order. If an
alarm occurs, the table helps to identify causes and remedies. The different causes
and remedies should be worked through in the order listed until the alarm has been
resolved.
To help service personnel, all failures and error codes should be recorded.
