Alarm display in home view
Alarms are shown in the alarm overview as follows:
1
The alarm is active, i.e. the alarm cause has not yet been
remediated. But the alarm has already be acknowledged.
Therefore, the acknowledgement button is no longer displayed.
2
The alarm is active, i.e. the alarm cause has not yet been
remediated. The alarm has not yet been acknowledged.
Therefore, the acknowledgement button is displayed.
3
The alarm is no longer active, i.e. the alarm cause has been
remediated. That is why the alarm appears in brackets.
However, the alarm has not yet been acknowledged.
Therefore, the acknowledgement button is displayed.
If an alarm becomes inactive, i.e. the alarm cause has been
remediated,
and
the alarm has been acknowledged by the user, then it
will disappear completely from the alarm overview.
No acknowledgement button appears for the flow report if the setting
Alarm for missing flow signal
is set to
no
, as no acknowledgement is
required in that case.

Alarm display in home view
All active alarms are displayed in the Home view; see section

view.
16.5
Dosage blocking via alarms
Alarms generally result in dosage blocking. The block is automatically
released as soon as the alarm cause has been remediated.
It is not necessary for a user to acknowledge an alarm in order to end
blocking (however, the alarm continues to be displayed in
Alarm
overview
until acknowledgement).
The following alarms are handled in deviation to that mechanism:
•
If the setting
Alarm for missing flow signal
is set to
yes
, then
dosage blocking is not ended until a flow signal is present again
and
the flow alarm has been acknowledged by the user. Dosage
will then be released after start delay has passed.
•
If the setting
Alarm for missing flow signal
is set to
no
, then
dosage blocking is not ended once a flow signal is present again.
Dosage will then be released after start delay has passed.
•
The menu
Alarm settings
can be used to establish whether a level
alarm will lead to dosage blocking. The default setting is that a
level alarm will block dosage of the respective control module
(pH, Cl, mV, O2).
•
After a dosage alarm, dosage is released immediately after
manual acknowledgement of the alarm.
