A1.1.3 Warning / alarm display and acknowledgement
Each new warning / alarm is displayed when it occurs, overwriting any text already present unless another
unacknowledged warning / alarm is currently being displayed. The corresponding Warning / Alarm LED flashes to
indicate a new warning / alarm.
Pressing ENTER acknowledges the warning / alarm currently displayed and the Warning / Alarm LED stops flashing.
If available the display will show the suggested action, press ENTER again to clear.
If there is another new warning or alarm the Warning / Alarm LED will continue to flash and this is then displayed,
otherwise the display will revert to the original text from before the alarm(s) / warning(s) occurred.
If there are warnings / alarms still present, but they are all acknowledged, then the corresponding LED remains
continuously illuminated. The text indicating acknowledged warning / alarm conditions still present may be viewed
in the Status menu, see below. Some Alarms such as 1.01 STOP ACTIVATED remain present until the pump is manually
started from the PDT or front panel controls.
Once all warning/alarm conditions have gone away, then the corresponding LED is extinguished.
To avoid a build up of out of date Warnings they are automatically acknowledged after 36 hours.
