12.13 Alarm – Cause – Remedy
Alarm messages are displayed in hierarchal form in the alarm message field of the
header bar, see page 154.
The priority of the alarm messages is indicated by different background colors.
In the Current alarms and Logbook tables, the priority of the alarm messages is
also indicated by exclamation marks.
In order to classify alarms having the same alarm priority, internal priority numbers
are given in the table below. The most critical alarm within an alarm priority is given
the number 255.
The following table lists the alarm messages in alphabetical order. If an alarm
occurs, the table helps to quickly identify causes and remedies. The possible
causes and remedial measures should be looked through in the order they are
listed until the alarm is resolved.
Some alarms are listed several times because their priority may change under
certain conditions, see page 160.
Some alarms only occur if the corresponding option is installed.
