RSD Rain Sensor
2
Set Vent Ring
The vent ring determines drying time the length of time
the sensor turns off irrigation after a rainfall. For most
installations, set the vent ring to the fully open position.
For some installations, such as sites where water pools after
rainfall, set the vent ring to a partially open position. This will
shut down the irrigation system a little longer after a rain.
To set the vent ring, turn the vent ring knob below the dial
cap to the desired position, as shown in
Illustration 3
.
3. Mounting
NOTE:
Follow the installation instructions carefully and
install the unit only in full compliance with the National
Electrical Code (NEC) or your local electrical code.
Bracket Model
To install the RSD-BEx Rain Sensor bracket model:
1. Select an appropriate mounting location within 25'
(7,6m) of your controller.
2. Drive two mounting screws through the mounting holes
(A) in the main mounting bracket, as shown in
Illustration 4 (A)
. Use fasteners appropriate for the
mounting surface (wood, tile, masonry, etc.)
Conduit Model
To install the RSD-CEx Rain Sensor conduit model:
1. Thread the Rain Sensors lead wires through an adaptor
fitting appropriate for your installation and screw the
sensor into the adaptor, as shown in
Illustration 5
.
2. Make sure the Rain Sensor head is level and extends far
enough beyond the roofline to receive unobstructed
rainfall.
3. Run the extension wires through the conduit (if
necessary, follow the procedure for wiring a Normally
Open controller, as described in Section 4 Rain Sensor
Wiring).
4. Secure the adapter fitting to the conduit. Then connect
the Rain Sensor to the controller using the appropriate
procedure, as described in Section 4.
4. Rain Sensor Wiring
All Rain Bird controllers, and most controllers by other
manufacturers, are installed using a Normally Closed
method. Select the appropriate procedure to install the
RSD Rain Sensor to your controller.
