Pressing the alarm bell icon will bring up the alarm page (as shown below) which will identify which
alarms are active.
The alarm descriptions may be accessed by selecting the vertical columns where the alarm(s) appear
(as shown below).
Some alarms will ‘self-clear’ if the condition is a transient one (e.g. a temperature goes over an alarm
threshold then comes back to a healthy condition) or when the fault has been rectified (e.g. a faulty
sensor has been replaced).
Latching alarms will need to be manually cleared when logged on at the Service level or higher, by
pressing the ‘Clear Alarms’ button on either of the screens above.
