Chapter 1: Introducing Ranger 4000 S
The Ranger 4000 S is a microprocessor based irrigation control system. A
central controller and up to 100 field stations comprise a complete system.
In addition the controller will accept input from several external sensors in
order to adjust its irrigation to the local weather conditions.
The Controller
The heart of a Ranger 4000 S based system is the controller. This is a
microprocessor controlled device that stores your irrigation programs and
Ranger 4000 S individual stations in the field when to activate their
valve(s).
Irrigation Features
Here are the main features that the Ranger 4000 S utilizes to help you
automate your irrigation:
• Controls up to 100 solenoids attached to valves or relays via the
built‐in connection board and three expansion boards.
• Provides ET corrected irrigation for optimal adjusted water
consumption.
• Measures water flow and raises alarms or halts irrigation on
unexpected flow.
• Allows for 10 independent irrigation programs. In addition there is
a fixed test program that activates all 100 stations in turn.
• A program can activate up to 100 stations in named order.
• Each station can run for up to 17:59:50 (In fact, you can boost this
even further by increasing the "water budget".
• Each program can activate a one or more booster pumps in addition
to the stations.
• Master valves and booster pumps will be activated in parallel in all
