Instructions for use Primus Infinity Empowered SW 4.5n
Alarm – Cause – Remedy
Primus Infinity Empowered divides the alarm mes-
sages into three priority classes identified by differ-
ent colors:
Technical alarms identified by an asterisk "*" can be
downgraded to lower priority or canceled altogether
by pressing the key. For these alarms the lower
priority is shown following the "/" (if a dash (–) is
shown, it means that alarm can be canceled).
The messages are listed below in alphabetical or-
der. The list is intended to help identify the cause of
an alarm message and to remedy the fault rapidly.
Internal priority numbers for ranking alarms within a
class (see page 128) are written in parentheses,
e.g. (23 / 31), in the table below.
Warning = Message with high priority (red)
Caution = Message with medium priority
(yellow)
Note = Message with low priority (cyan)
