The Set-up panel is used to:
•
set up alarm severity levels when exceeding the quality thresholds in 15-minute
and 24-hour periods, set up alarm switch-on and switch-off thresholds when exceeding
the quality thresholds in 15-minute and 24-hour periods,
•
set up alarm switch-on and switch-off thresholds when exceeding the quality thresholds
in 15-minute and 24-hour periods
Figure 16. Interfaces - set-up
Alarm severity levels when exceeding the switch-on threshold can be as follows:
•
UAL – urgent alarm,
•
NUAL – non-urgent alarm
•
NONE – no alarm is generated
A switch-on threshold defines the number of seconds, after exceeding of which an alarm
specified by a severity level is activated.
A switch-off threshold defines the number of seconds, which specifies deactivation
of an alarm specified by a severity level, if the counted number of seconds is less or equal
to the threshold at the end of a given period.
The table below shows allowable alarm statuses (severity levels) and allowable values
of alarm switch-on and switch-off thresholds when exceeding ES and SES threshold values.
