Connecting a Pump Control
Caution: Do not be connect the controller directly to the pump motor or starter. A 24 VAC isolation relay; i.e.,
Irritrol SR-1 Pump Start Relay (or equivalent), must be used to facilitate the pump control circuit connection.
1. Install a 24 VAC pump start or equivalent
isolation relay. Route and connect a control
wire and a common wire from the Pump
terminal of the Pump/Master Valve terminal
block to the relay. See Figure 8.
2. Connect the remaining pump wiring per
the instructions provided by the pump
equipment manufacturer.
Caution: If multiple controllers are
utilized within the irrigation system, do
not interconnect the controllers’ eld
common, pump or master valve wires.
Damage to the controllers can result.
Note: Contact technical support at 1-800-777-1477 for information regarding multiple-controller wire connections.
The Eagle Plus controller provides connection terminals for two ow sensors, a Rain Master Weather Center II or an
Irritrol Rain/Freeze sensor. Installation of this equipment must be made in accordance with the instructions provided
with each device. The wire connections to the controller are made per the diagram in Figure 7.
Caution: To prevent damage to the controller and/or
sensor equipment, turn o power to the controller prior
to connecting sensor wires.
Installation Notes:
• The sensor connection terminals accept 18–22 AWG
(0,8mm
2
–0,5mm
2
) solid-core copper wire. To enable
positive wire retention, insulation must be removed from
the end of each wire to expose ⁄ –½” (10–13mm) bare
copper wire.
• Flow sensors and Weather Center II connection wires
have specic polarity that must be maintained for proper
operation of these devices. Note the + /– indicators on each
sensor connection terminal and connect accordingly.
• The controller can support input from the Weather Central II weather station or an Irritrol rain or rain/freeze sensor. Both
sensor inputs cannot be used together.
• A jumper wire installed between the RN(+) and RN(–) terminals must not be removed unless a (normally-closed) rain sensor
is connected.
• Refer to the Eagle Plus User’s Guide for information regarding compatible ow sensors and corresponding setup parameters.
Programming the Decoders
Rain Master decoders are congured in 1-, 2-, and 4-station models, and as shipped from the factory, have no
pre-defined station assignments. In order to be recognized by the Eagle Plus controller, each station must be dened
as a either a station number from 1 to 200, a Master Valve control, or a Pump control. To facilitate decoder programming,
a quick-connect terminal block is provided on the Two-Wire Decoder module board. See Figure 8.
Note: The Eagle Plus enables the decoders to be temporarily
connected and programmed without disconnecting power.
1. Insert the red and black decoder wires into the corresponding
terminal block positions.
2. Press the SETUP key to display
the SETUP menu. The CONTROLLER
menu item is chosen by default.
Turn the Dial right ve steps to
choose the TWOWIRE menu option,
then press the Dial to select.
3. The SETUP TWOWIRE menu
screen is displayed with PROGRAM
DECODER option chosen by default.
Press the Dial to select. Status LEDs
on the decoder and decoder board will begin blinking to conrm communication.
4. The PROGRAM DECODER screen will be displayed with the NEW ADDRESS option
chosen.
Note: In this example, NONE indicates that decoder station slot 1 (1 of 4 available slots) has
no existing address.
5. To select a dierent decoder station slot number, turn the Dial to choose the slot
number, then press the Dial to select. Turn the Dial to display the preferred number, then
press the Dial to enter.
