• It may take a full hour or longer to learn flows for
an entire 42-station controller. Each station may
take from 35 seconds to 5 minutes to be learned,
depending on stability of the flow.
Step 5: Review And Edit Flow
The flow values and settings for each station can be
reviewed, and manually edited, at the Set Flow Monitoring
dial position. It is important to verify the flow settings for
each station before leaving the controller in automatic
operation.
• Turn the dial to the Set Flow Monitoring position.
• Use the up and down arrows to navigate through all
stations, and verify that they have a learned flow or a
Not Monitored setting.
• Do not leave any station with a "Not Learned" message-
either enter a flow manually, or set it to Not Monitored.
• To edit a station's flow data, turn the dial to any other
position, hold down the Information button, and turn
the dial back to the Set Flow Monitoring position.
Select "EDIT LEARNED FLOW."
• Use the up and down arrow buttons to move through
each station.
• Use the +/- buttons to adjust the flow. Each station
can be set from 0.5 GPM (1.9 LPM) to 999.5 GPM
(2770LPM) in 0.5 GPM /1.9 LM increments. Between
the highest value (999.5) and the lowest (0.5/1.9
LPM), the Not Learned and Not Monitored choices
also appear, as the +/- buttons are pressed.
You can manually replace a Learned flow with another
value, if you wish.
• LIMIT: Use the left and right arrow buttons to move to
the Limit field (LMT) to edit it, if desired.
28
The default Limit is always 115%, meaning the station
must exceed the flow by 15% before it will be treated
as an alarm (to prevent false alarms due to normal flow
fluctuations). 110% is the minimum possible Limit
setting, and 300% is the maximum.
• DELAY: Use the left and right arrows to move to the
Delay setting to edit it, if desired.
The default delay is 01:00 in minutes:seconds format. This
means the station's flow will be ignored for the first 1:00
of operation, before the flow will be considered for alarm
purposes. The Delay can be set from 0:15 to a maximum of
9:59. Some delay is recommended to prevent false alarms,
particularly when stations are initially activated.
You can Copy and Paste to edit flow settings for multiple
stations with similar characteristics. Select the station
with the Flow you wish to copy and press the Copy button.
You may then Paste (Paste button) the flow value into any
other stations.
The Limit and Delay settings may also be copied and
pasted together, separately from the Flow Value.
• Review all stations to verify their flows, limits, and
delays.
• Once station flows have been learned, flow monitoring
is in effect. If the Information button is pressed during
irrigation, the actual flow will be shown, along with
the combined limit of all active stations.
• Stations that do not operate irrigation devices,
and stations that are not used, must be set to Not
Monitored to avoid false alarms.
flOW AlArMS
When a Flow Alarm has been detected, the controller will
begin diagnostics, which can be seen in the display.
The controller will shut down all station activity for 1 full
minute. The display will show the stations as Paused
during this interval.
The controller will then test each station that was running
at the time of the alarm, individually. It will start the
lowest-numbered station that had been running, and allow
it to run for the Delay period set in Set Flow Monitoring.
After the Delay has elapsed, it will sample the flow rate, to
see if it is within the Flow Limit.
