ADDITIONAL FEATURES
Live feedback from the valves.
Reliable two-way data communication every 20 seconds. There is a big difference between moni-
toring networks and true valve control. The TWIG technology has very short time latency, which is
the lag time from initiating a request to a network and receiving the response. Think about turning on
a faucet and waiting for the water to ow (latency) compared to the amount of water that comes out
(throughput). The latency of many other networks is like an old pump well in which you have to prime
it to get the ow started; on a TWIG network, it’s like the fast convenience of pressurized indoor
plumbing. Less latency means better, quicker valve response. Status reports are always up to date;
sent to the controller showing the actual battery voltage and radio signal strength of each TWIG in
the network.
Manual control can be done two ways.
All Nelson valves have the option of manual control with the selector handle on the valve or by using
the TD200 ‘manual control’ to close or open a valve immediately. Also the TWIG is capable of run-
ning a short manual solenoid test to check the solenoid function.
OFF/RUN/PAUSE Controller feature.
A OFF/RUN/PAUSE gives full eld control.
-The OFF mode, the program is kept from operating (and valves are not allowed to open) until
the TWIG modules receive an ON command.
-The RUN feature is used often by irrigation eld personnel. Programs can be run without the
work of changing anything. No programming the controller. Just turn the dial to RUN.
-The PAUSE feature closes ALL the valves for all running programs. The valves remain closed
until the dial is rotated back to RUN and irrigation resumes where the program(s) were when paused.
Reviewing a program.
The TD200 system lets the user quickly review the programs and rapidly advance the time to make
sure any errors can be corrected. Simply go to the manual control and move through the groups.
