Features of D-1900 system
| Sector | D-1900A | D-1900B |
|---|---|---|
| Method of Contro |
•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 time |
| Method 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 sector | ||
| Nutrient |
•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 |
•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 |
