Connecting the conventional field wires
Connecting Sensors
The Ranger 4000 S takes input from different sensor types: ET devices, rain
sensors, flow sensors and regular auxiliary alarms. This sections shows you
how to connect these sensors to the controller.
Connecting an ET Device
The Ranger 4000 S supports ET in two ways:
1. "ET Enabled" mode in which the controller just lets an external device
tell it when to irrigate and when to stay passive. In this mode the controller
supports two ET devices: WR‐7 and WR100i. To make the controller receive
instructions from an ET device, connect the "ET enable A" from the device
to the green terminals labeled "ET."
2. "ET Pulses" mode where you connect a weather station that
continuously tells the controller how much water is evaporating.
Combined with the input from a rain sensor the controller will then on its
own figure out how much to irrigate. Running in this mode you still just
connect the weather station to the ET terminals.
