Instructions for Use Oxylog 2000 plus SW 1.n
Alarm - Cause - Remedy
Oxylog 2000 plus classifies alarm messages
according to three priority levels and identifies
these accordingly with the aid of exclamation
marks:
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 cause of the
alarm has been resolved.
When multiple alarms occur, they are displayed
according to their Alarm Rank, as illustrated in the
table below. A lower number has a higher rank.

be reconnected to the mains sup-
ply, an onboard DC supply or a
fully charged battery.
