Confirming and/or deleting Alarms

The operator has the following options for reacting to
alarm messages:
• Confirm the alarm in the superimposed window with
"Acknowledge". The alarm message in the header and
red highlighting of the alarm symbol are deleted. The
alarm is listed as a "confirmed" alarm ("ACK") in the
list of alarms.
•
Close the superimposed window without confirming
with [ X ]. The alarm message remains in the header
and red highlighting of the alarm symbol is retained.
The alarm is listed as an "unconfirmed" alarm
("UNACK") in the list of alarms.
• Call up the alarm list with the main function key
„[ ]". Unconfirmed alarms can be confirmed there
with "ACK". Pressing "RST" ("Reset") deletes the
message from the alarm list.
•
How to react to alarms and other messages depends
on their type and cause. The following tables give an
overview. If you have any queries about alarms and
suitable measures for their remedy, please contact
Sartorius Stedim Biotech GmbH.
