● 4 independent programs (3 for solar radiation / 1 for moisture sensor and external sensor)
● With one solar sensor, each operation is performed independently of three programs by the amount of accumulated insolation.
● Apply solar (light) coefficient [-Ec:00%] and moisture coefficient [+00%] in 3 solar-only programs.
● Nutrient solution = 2ea (A-B) + Acid/base + Auxiliary liquid ratio = 4ea / Irrigation valve area = 16ea
● By 4 programs: Select nutrient solution from 2 nutrient solutions (A-B) / Select acid/base / Select auxiliary solution ratio.
● For each of the 4 programs: Select the amount of irrigation - Minutes: Seconds (00:00)/Flow rate (0000L) are selected and operated respectively.
● Option: flow meter = automatic control switching device due to flow meter failure when supplying the amount of irrigation as flow;
● In the dedicated program for moisture sensor and external sensor = Program designation for each external sensor (P-4).
● Independent operation by external sensor and time interval / time designation (20 times) for each of 4 programs.
● After completing irrigation for each of the 4 programs, it is possible to wash the raw water for each valve.
● Basic : Ec sensor 1ea / pH sensor 1ea
● Option: E-2 = reprocessing sensor / pH-2 = reprocessing sensor can be attached. By setting the reprocessing range,
Alarm and block at the same time when the reprocessed nutrient solution mixture flows out of the set range
● Ec/pH in the program = Adjust the upper/lower alarm value input and operate the safety device when the information value is reached
● Calibration of sensor values of Ec-1/2 and pH-1/2 in the program and correction of insolation sensor sensor values
● Source: Daily 4 programs - number of irrigation / irrigation flow rate and irrigation time for 16 valves
The average EC value and pH value for each of 16 valves is stored and viewed for one year.
