How the Systems Works
Water is piped from the water main into a holding tank then pumped by a pressure pump, usually 3hp (2.2Kw) single or three phase, into a ‘ring main’ of 50mm polyethylene pipe round the green.
One high capacity pop-up sprinkler is installed in the middle of each side.
The Sprinklers incorporate built-in valve, which are linked to the controller by 0.8mm low voltage cable laid with the pipe. Normally closed, the valves are opened by the controller for an individually pre-determined time, allowing each sprinkler to operate individually, discharging at 30 g.p.m. at 60-70 p.s.i. (8m³/hr at 4.8 bar).
The controller has three independent programs with 4 start times per program for a total of up to 12 start times per day. Watering times shall be available from 1 to 99 minutes in 1-minute increments per station. Controller has a weekly 7-day calendar or a 1 - 31 days interval watering, that allows user to choose day(s) of week for desired watering. Operation shall be available in automatic, semi-automatic and manual modes. Battery back-up shall retain the time when there is power cuts. The controller has a none volatile memory, therefore the battery is not required to maintain the program settings. All programming shall be accomplished by use of a programming dial and selection buttons with user feedback provided by a LCD display.
The control panel is pre-wired with one connection box for ease of installation. The control panel also incorporates a low water cut out linked to a low level float switch to be installed in the water tank.
