This Technical Note describes the two kinds of protection against lightning damage in decoder based 2 or 3 wire irrigation control systems. When properly installed, lightning protection in decoder systems will generally be stronger than that found in smaller multi-wire systems. The exception is pedestal-mounted multi-wire, where extensive extra lightning protection components are housed within […]
Basic Knowledge Required to Decide on Efficiency The total area to be irrigated. The amount of irrigation applied over the period. The amount of rainfall received over the period. The amount of water needed by the turf over the period. Only then can comparisons be made between one course and another. What happens to applied […]
Irrigation solenoids are used in control valves to open a pilot hole. This allows water pressure to decrease on the top side of a diaphragm. The diaphragm is then pushed away from the seat by the water pressure below so water flows through the valve to the sprinklers etc. To understand solenoid action, it is […]
Year on year, we are all used to electronics getting cheaper and giving more value. Just take mobile phones as an example. However, these advances haven’t found their way into the control of medium-sized landscape and playing fields irrigation. The current way is to have a controller with many terminals, each with a wire to […]
The main reason for making sure there is no water in the pipes and pumps is to prevent frost damage. A well designed irrigation system will have drain valves around the pipe work at hopefully, the lowest points! To get these to work and the water to come out, air must get in. However it […]
Most irrigation controllers are programmed in minutes per station. The person in charge of irrigation is usually very busy with other jobs, so 10 minutes per golf Green is the default. Using this rule, it is very likely that the ground is being over-watered to some extent. Under watering on the other hand shows up […]
There are a number of things you can do, each small and inexpensive, which can save you all of the above. Get a straight-sided 1L plastic jug. Fill it with water up to about 1cm from the top. Put it on a bar stool about 1m above the ground in an open area. Measure the […]
