Normally Closed Installation
!
NOTE:
Open" is not used with this installation method.
If installed with a Rain Bird controller, follow
the Normally Closed installation procedure.
Controllers With Rain Sensor Terminals
Many modern controllers (such as Rain Bird's ESP-LX
Modular and STPi) include built-in terminals for rain
sensor lead wires. Dedicated rain sensor terminals are
usually labeled "sensor", "S" or "SN" on the controller's
terminal strip.
1.
To connect the rain sensor, remove the jumper
wire (if present) from the controller's rain sensor
terminals.
2.
Connect the red or black lead wires from the
rain sensor to the controller's sensor terminals,
as shown in Figure 6.
Controllers Without Rain Sensor Terminals
Use the procedure below if your controller does NOT
have dedicated rain sensor terminals.
1.
Disconnect the wire from the common terminal
("C" or "COM") on the controller's terminal strip.
Then connect this wire to either the red or black
Rain Sensor lead wire.
2.
Connect the remaining Rain Sensor lead wire
(do not use blue wire) to the common terminal
("C" or "COM") on the controller's terminal strip,
as shown in Figure 7.
Normally Open Installation
Some non-Rain Bird controllers require rain sensors
to be installed "Normally Open" (N.O.). Use the
following procedure if your controller requires
normally open installation.
1.
Connect either the red or black Rain Sensor lead
wire to the blue wire labeled "Normally Open".
2. Seal the connection in accordance with the
National Electrical Code (NEC) or your local
electrical code.
3.
Consult your controller's manufacturer's manual
to determine the appropriate procedure for
connecting the Rain Sensor to your controller.
