5. If the flow sensor selection has been changed to
NONE after learning, the display will show FLOW
NOT MONITORED. The actual flow may still be
viewed, even if all stations have been set to Not
Monitored. Station level alarm diagnostics would
not be available, but the flow will be visible.
Step 3: Preparing for Flow Learning
1. ACC will only learn flows for stations which have
run times in Automatic Programs. Verify that each
station has a run time in an Automatic Program (A
through F).
2. ACC can be taught to ignore flow monitoring for
stations which operate non-irrigation devices.
3. Turn the dial to another position, then hold the
Information button while turning back to the Set
Flow Monitoring position.
4. Select Edit Learned Flow (even if no flow has been
learned, yet).
5. Use the – button to set the non-irrigation stations to
Not Monitored. Use the up and down arrow buttons
to advance through the stations, and set any stations
necessary to the Not Monitored setting.
Step 4: Learning the Flow
1. Turn the dial back to the RUN position.
2. Press the LEARN button. The screen will display that
the controller will run the stations and it will also ask
you to confirm that you want to begin watering to
learn flow.
3. The ACC will begin watering at the lowest station
number to learn its typical flow. Normally this will be
station 01, unless it is Not Monitored or has no run
time in any programs.
It will run the station for a minimum of 15 seconds, and
then begin sampling flow at 5-second intervals until flow
has stabilized (at least 4 readings, 5 seconds apart, within
a reasonable flow range of one another). It will then store
the average flow for this station in its memory, and move
on to the next station. It will continue in this manner
through all stations which have at least one run time in
one of the Automatic Programs, and which are not set to
Not Monitored in the Set Flow Monitoring station settings.
Only stations with a run time in an Automatic Program
will be learned. Stations which are not programmed in any
Programs will not be sampled, and should be set to Not
Monitored to ensure proper operation of the flow meter.
If the station Delay setting has been changed, the controller
will run the station for Delay period (instead of the 15
second minimum) before sampling and learning flow.
