Reviewing alarms |
The Access triggers alarms in case of off-limit performance, component malfunction or other error.
List of active alarms can be accessed by clicking the "bell" icon. The digit in the circle indicates number of active alarms.
The list contains up to 20 of the latest alarms and displays the name, level and status. The list is populated by the system number of the alarm and does not reflect sequence of appearance. The sequence of appearance can be reviewed in the alarm history.
Level of the alarm is indicated by the icon:
|
Class A. Used to indicate critical errors (e.g. activation of freeze protection) |
|
Class B. Used to indicate non critical errors (e.g. filter alarm) |
|
Class C. Used to inform (e.g. manual operation) |
Status indicates state of the alarm:
- Alarmed - conditions for the alarm are still present.
- Returned - conditions for the alarms have returned to pre-alarm state
- Acknowledged - alarm has been reviewed by the operator but conditions for the alarm are still present
The alarm is cleared from the list if it has been acknowledged and conditions for the alarms have returned to pre-alarm state.
Each alarm should be acknowledged deliberately after investigating causes of it. It is possible to acknowledge alarms individually or all at once.
The alarm is also cleared from the main alarm list if it has been blocked by the operator. Such alarms remain listed and can be unblocked in the extended all alarms list (Data & Settings > Alarm list > Show all alarms)
