STEPS FOR CONVERTING A RISER/ELBOW TYPE VALVE SYSTEM FOR AUTOMATION
Typically manual riser valve systems require every move be done by hand so switching to
automation is a big change. The change must be complete in all aspects of system hardware,
irrigation schedules and operating mind set. Note that the 1
st
rule of automation is to use a pressure
relief valve to keep pressure limited so damage to pipes can be avoided!
1) The rst step is to remove the existing valves from the risers and adapt each riser to the Nelson
800 Series or 1000 Series. These Nelson valves can be operated using a solenoid to open and
close the valves. Make sure that the valve has the required lter which will keep the solenoid
clean.
2) Consideration should be given for using the elbow version of the 1000 Series because it
provides hydraulic control and the elbow is built within the valve.
3) Often the existing system has been moved by hand. Make sure to selected connection for the
automatic valve is easy to attach in the event that the system will continue to be moved.
4) Select a good location for the TD200 controller. Make sure that there is room for a tall antenna.
Use 110 VAC power source if possible. Many growers want the controller near the pump so they
can watch as the system starts and lls the pipes.
5) Power up the TD200 because it is the base of the TWIG network.
6) The eld site form can be used that is in the User Guide. Do a site survey of the distances
between the valves and the location of the controller. The radio signal can be checked using
the TD200 and TWIGs (after the TWIG is joined to the TD200). Plan for a repeater and select
an appropriate location. The preferred location will have 110 AC power but if a battery must be
used then plan for a solar kit.
7) Properly select the TWIG mounting bracket so that the TWIG can be connected in the upright
position.
8) If a solenoid is already on the valve make sure that it is the approved 12VDC latching type.
9) Place the TWIGs in the eld at the valve locations and make a eld map showing the address of
each TWIG.
10) Connect the wires between the TWIG and solenoid. Polarity must be respected and only the
Nelson approved connectors used.
11) Verify the solenoid operation by actuating the coil using the TWIG menu -SOL-.
12) Return to the TD200 and make sure that all TWIGs have joined the network and every signal is
above a number 20. Using the eld map that has the TWIG addresses create the program(s) and
the Groups to automatically run the system
