9.12 Alarm memory menu
The last 10 occurred and signalled alarms are saved and displayed in the alarm memory. The latest
alarm is on memory space 1, the oldest alarm on memory space 10. The alarm memory works as
sliding buffer. If a new alarm is signalled, this is saved at the first space. In the process, all previously
available entries (1-10) from memory space 1 onwards are each moved on by one memory space. As
a consequence, the alarm previously saved under memory space 10 is deleted. The alarm memory is
non-volatile. This may be deleted completely by simultaneously pressing the keys "
" and "
" for
approx. 3 s in the alarm memory menu. The alarm memory may also be deleted under SETUP/606.
NOTE:
As a consequence, all alarms signalled on the display and the alarm relay are also reset, if no
alarm is active anymore.
