ET Manager Series - Installation and Operation Manual 13

Wiring Diagrams

The most common Output Method for the ET Manager

is to interrupt the valve common output of a sprinkler

controller until watering is needed. This is referred to

as the “Enable” Output Method. The ET Manager can

support two Valve Groups, A and B. The valve common

from the sprinkler controller is wired into the ET

Manager and the Valve Groups A and B common wires

run from the ET Manager to the sprinkler control

valves. A separate common wire is required for each

valve group. See Figure 7 for the Enable Output

Method wiring diagram.

Note: The wiring diagrams for advanced Output

Methods are included in chapter 8.

Optional Rain Gauge

Rain measurements are provided from the remote

weather station operated by the WRSP. If site-specific

rainfall measurements are desired, mount the optional

on-site tipping rain gauge (Model ETM-RG). The

optional rain gauge will be used by the ET Manager in

place of the weather station rain information.

A local on-site rain gauge can be connected to the ET

Manager. The rain gauge must be a tipping gauge with

an output measurement at either 0.01" or 1.0 mm per

tip. The on-site rainfall value can be used in place of

the rainfall value broadcast in the weather signal to

provide actual on-site rain data.

The Tipping Rain Gauge (Model ETM-RG) is an option-

al rain gauge available from Rain Bird for use with the

ET Manager. The rain gauge contacts can be either

normally open or normally closed.
