Hunter X-Core Owners Manual And Programming Instructions page 115

If the station passes (runs within the Limit), the controller
will Pause the station, and move on to test the next station
that had been running (if applicable).
If the station fails, (runs outside of the Limit), the station's
run time will be ended, and an alarm message will be
placed in the Alarm Log.
The display will show ATTENTION: Flow Alarm if any
stations have failed the test. Irrigation (for passing
stations) continues to run normally, even if this display is
present.
Details for the stations that failed, including time of day
and Over or Underflow, will be stored in the Alarm Log
(Data History dial position).
To get detailed information about any Attention display,
turn the dial to Data History and select the Alarm Log.
After irrigation is completed, the display will continue to
show that alarms occurred, until any button is pressed.
This will usually result in multiple flow alarms since ACC
will try to restart stations after Pausing for one minute.
Since ACC can run multiple stations at once (Overlap,
SSGs, etc.), it will add up the learned flows for all stations
that are running, and compare the total to the actual flow,
in real time. If an alarm occurs with multiple stations, ACC
will enter a diagnostic mode to try to isolate the problem
stations.
All station delays must be met before the alarm will occur.
If multiple stations are running and have different delay
times set for Flow Alarm limits, the longest delay must be
met before the alarm will occur.

To view the diagnostics while they are in progress, press
the Information button. This will clear the Attention, Flow
Alarm display and show the actual status of the affected
stations. While isolation is in progress, the display will
then show individual stations in Pause status, as each
station's flow is sampled one at a time.

See Data History on page 38 for more information.
When a Flow Alarm is shown on the display, turn the dial
to Data History to view the Alarm Logs for an explanation
of the alarm (select Alarm Logs and press +).
The Last Event is always shown first. Press the – button to
step backwards through the logs to view them one at a time.
A Missed Irrigation report will be logged for each station
event that causes a station to shut down for Overflow or
Underflow reasons. The report will show the date and time
of the event, and which type of flow alarm occurred (Over
or Under).
