Item D-1900A D-1900B Method of Control • Time control : Irrigation works up to 24 times at the setting time
• Interval control : Irrigation works depending on start/finish time/interval(min-utes, seconds(max. 99 times)
• Light intensity control : Irrigation works depending on accumulated light/max/min time• Interval control : Irrigation works depending on start/finish time/interval(minutes, seconds(max. 99 times)
• Light intensity control : Irrigation works depending on accumulated light/max/min timeMethod of Irrigation • Irrigation by flow rate : Irrigation works depending on the setting of 10L unit per sector
• Irrigation by time : Irrigation works depending on the setting of time unit, "minute/second," per sectorNutrient solution • 3 nutrient solution tanks can be used(A, B, C solution tank) Electronic valve • Irrigation can be extended up to 10 sectors(additional sector is possible as options) Other control • 2 terminals are available for the control of additional pumps(AC 24V) Features
of the
Program• Electronic valve control per sector :
Control from sector 1 in order
• Agitation : Setting(basic) for manual and
automatic agitation
• Irrigation setting : Setting of EC/pH/amount of
irrigation per sector
• Time control : Setting of nutrient solution to be
used for each irrigation time
• Additional setting of irrigation on specific time,
particularly in summer
• Irrigation report : Saving weekly amount/number
of irrigation/accumulated light
• Warning of nutrient solution : Setting the limit of
high/low value of EC/pH to give warning signal,
shutdown.
• Output test : Output test for the system can be
performed
• 1 time irrigation :1 time irrigation works by
one-touch button other than time setting
• Pause : One-touch emergency shutoff function
• Error display : Message & corrective action for
error is displayed
• Indication of non-irrigation sector
(when controlling the flow rate)• Electronic valve control per sector :
Independent control, duplicate setting per sector
• Agitation : Setting(basic) for manual and
automatic agitation
• Irrigation setting : Setting of EC/pH/amount of
irrigation per sector
• Time control : Setting of nutrient solution to
be used for each irrigation time
• Additional setting of irrigation on specific time,
particularly in summer
• Irrigation report : Saving weekly amount/number
of irrigation/accumulated light
• Warning of nutrient solution : Setting the limit
of high/low value of EC/pH to give warning signal,
shutdown.
• Output test : Output test for the system can be
performed
• 1 time irrigation :1 time irrigation works by
one-touch button other than time setting
• Pause : One-touch emergency shutoff function
• Error display : Message & corrective action for
error is displayed
• Indication of non-irrigation sector
(when controlling the flow rate)Features
of the
Hardware• Nutrient solution control valve on the front : Current value of nutrient solution can be controlled
• Installation space can be minimized due to the solution control valve on the front
• Anti-lightening circuit, components are built in
• Big size of Korean LCD(Korean character 40x4) with bring screen
• Hydraulic valve : Continuous & safe supply of raw water to mixing tank
• Relief valve : Maintaining a stable pressure for irrigation per sector
• U-PVC pipe : Durable & chemical-resistant valves/pipes were used
• Switch box : Corrosion-resistant stainless steel was used
• Main structure : Main body is made with 40mm x 40mm aluminum profile
