Hunter X-Core Owners Manual And Programming Instructions page 128

An ADM Overcurrent message means the total draw on
the two-wire path(s) was greater than 2.2 amps, but the
ADM99 was not able to identify a particular station causing
the problem.
P/MV outputs have a max output of 0.325 A. Pump start
relays with very high current requirements may need a
dedicated transformer and an additional relay (such as
Hunter Model PSRB) for reliable operations.

Any ACC display that shows ATTENTION is indicating an
alarm or other condition that should be investigated. You
should immediately turn the dial to Data History and select
the Alarm Log to view all details associated with the alarm.
This will often reveal the real problem at a glance.
The ATTENTION message in the display will not stop
irrigation by itself, but the condition it is reporting may.
If a station is in Overcurrent, the station cannot run,
but other stations may continue running even when
ATTENTION is in the display. Press the information button
to clear the ATTENTION message if you want to see the
normal status screen.

A station has exceeded its learned flow upper limit during
irrigation. ACC totals the upper limit of the learned flow
for all running stations, and compares them to the actual
flow at the flow meter. When the combination of stations
exceeds the total upper limits (after all Delay times have
elapsed), the controller will Pause and go into alarm
diagnostic mode.
