     2 設 備 特 點

      （1）采用PLC+觸摸屏自動控制方式，穩定可靠、精致美觀、一鍵式啟動、操作簡單方便。 。

      （2）人性化3D設計，符合人機工程學;觸摸屏、開關、儀器、儀表設立高度位置，符合國人平均身高方便人工操作。

      （3）對各組件的動作如：水泵、閥門、水罐液位、設有動態監控畫面(有需要可以升級遠程監控)。

      （4）設管理權限，分別為：管理員、工程師、操作員三種級別的管理。

      （5）手動、自動模式轉換方便，具備特殊提醒功能，以防止非操作人員誤操作。

      （6）人性化的報警記錄與提示功能;當遇到濾材更換周期到、滿水、缺水、低壓、超壓在觸摸屏事件記錄欄會記錄，當遇到水質、壓力、流量出現異常會發出報警。

      （7）設水質糾偏功能，有最低使用水質預警功能，不會出現突發緊急的狀態。

      （8）制水系統與供水系統分開控制，如遇更換耗材，可不必停止供水或者制水。

      （9）RO產水、沖洗時間可設定，當用水高峰期，可調節產水時間，使用水點穩定用水。

     2 Equipment characteristics

      （1）PLC+ touch screen automatic control method, stable and reliable, delicate and beautiful, one button start, easy to operate。

      （2）Humanized 3D design, in accordance with human engineering; touch screen, switch, instrument, instrument set up a high position, in accordance with the average height of the Chinese people to facilitate the manual operation。

      （3）The various components of the action such as: water pump, valve, water level, a dynamic monitoring screen (there is a need to upgrade the remote monitoring)。

      （4）Set management authority, respectively: the administrator, engineers, operators of the three levels of management。

      （5）Manual, automatic mode conversion is convenient, with special remind function, to prevent non operator error operation。

      （6）Humanized alarm record and prompting function; when filter replacement cycle, full of water, water shortage, low pressure and overpressure in the touch screen event record column will record when meet water quality, pressure, flow appear abnormal alarm。

      （7）Water quality rectification function, there is a minimum use of water quality warning function, there will not be a state of emergency。

      （8）The water supply system and the water supply system are separately controlled, and the water supply and the water supply system can not be stopped。
