2.
Select the POC name to create a name to uniquely identify the POC.
3.
For POC used for, indicate whether the POC is used for
Irrigation
,
Non-Irrigation
, or
Not used
.
4.
For Master Valve, use
+/-
to select what type of Master Valve is installed. If there is no Master
Valve connected, Calsense recommends selecting
Normally Open
to prevent the controller from
activating the output and triggering a NO CURRENT alert.
5.
For Flow Meter, use
+/-
to select correct type. If using a third-party hydrometer with a reed
switch register, make sure you select the correct reed switch. For all other non-Calsense Flow
Meters, select
FMBX
.
•
If FMBX is selected as the Flow Meter type, set the appropriate K-value and offset. Refer
to the sensor manufacture’s documentation for the correct settings.
•
If a Reed Switch is selected as the Flow Meter Type, use
+/-
to set the register’s gallons
per pulse.
6.
For Pump wired to PUMP terminal, use
+/-
to select whether there is a pump attached to the
PUMP terminal or not. If set to no, the controller will not activate the pump output.
Note:
This setting only displays for terminal-based POCs, not 2-Wire.
Configuring a Bypass Manifold
A bypass manifold allows low flow readings on a large mainline. It does so by utilizing one or two smaller
flow meters attached to a large main.
When irrigation or a master valve override starts, the controller uses the bypass manifold to dynamically
manage flow through the appropriate size flow meter using the actual flow rates. The largest level of the
bypass manifold is initially opened to fill the mainline. The actual flow rate of the system is monitored,
and the controller determines which level is optimally suited to read the flow. Once the appropriate
level is determined, the master valves of the other levels are closed, and that level is opened. This
process continues throughout irrigation, dynamically opening and closing the master valves to ensure
flow is read across the widest range possible.
Note:
Only one master valve can be open at any given time. This means that a normally open master
valve on the smallest level will be closed when a larger level opens.
Benefits of using a bypass manifold include:
•
Allows low flow readings on a large mainline
•
Eliminates the need to double up low flowing valves to a single station output which is
sometimes done to generate a higher flow rate for large mainlines
•
Supports two and three levels
