the zone will be marked as good and watering will continue. If the variance is out of limit, then the zone
will be marked as a failure and shut down. This method allows watering to continue almost without
interruption, while isolating the faulty zone or zones.
To set up the mainline
1. Turn the dial to the Flow Menu position.
2. Press the NEXT button to select Mainline Setup, and then press the ENTR button. The Mainline Setup screen
displays.
3. In the Mainline Number field, press the + or – button to select the number of the mainline that you want to
set up.
4. Press the NEXT button to go to the Design Flow GPM field, and then press the + button to enter the amount
of flow in gallons per minute (GPM) that is allowed through the mainline for the irrigation system.
Note : Press and hold the + button or the – button to rapidly increase or decrease the number in the field.
5. Press the
NEXT
button to go to the
Pipe Fill Time
field, and then press the
+
button to enter the amount of
time that it takes to fill the pipe and achieve a steady flow rate after a valve change.
6. Press the NEXT button to go to the Limit by Flow field. If you want the controller to use the mainline design
flow to determine how many zones can run concurrently, press the + button to enter Y (yes).
7. Press the NEXT button to go to the High Alarm field. If you want to set an alarm for a high flow variance
condition, press the + button to enter a percentage in the field.
Example : If the expected flow is 50 GPM, and the High Alarm field is set to 10%, then the acceptable flow
range is up to 55 GPM (10% of 50 GPM is 5 GPM). A flow amount over 55 GPM would trigger the high flow
variance alarm.
8. Press the NEXT button to go to the High Shutdown field. If you want
the system to shut down when a high flow is detected, press the +
button to enter Y (yes).
9. Press the NEXT button to go to the Low Alarm field. If you want to set
an alarm for a low flow variance condition, press the + button to enter
a percentage in the field.
Example : If the expected flow is 50 GPM, and the Low Alarm field is set
to 10%, then the flow can decrease to 45 GPM (10% of 50 GPM is 5
GPM). A flow amount below 45 GPM would trigger the low flow
variance alarm.
10. Press the NEXT button to go to the Low Shutdown field. If you want the system to shut down when a low flow
is detected, press the + button to enter Y (yes).
11. When you have finished making changes, turn the dial to the Auto Run position.
Managing Concurrent Zones
In the BaseStation 3200, you manage the number of zones that can run concurrently at the following levels:
•
Mainline Flow Level – When you set up the design flow for the mainline and then set the Limit by Flow field to
Y (yes), the system uses the mainline design flow to determine how many zones can run concurrently. Refer to
Mainline Setup overview on page 59.
• Controller and Program Level – If you want the controller to water more than one zone at a time, you must
configure the Zone Concurrency settings at the controller and program level.
