10.4 Dosing Configuration
Type of each channel configured by technician during installation process
EC- channel influenced by EC levels
ACID- channel to inject acid to reduce pH levels
PASSIVE- no EC/pH influence
ALKALI- channel to increase pH levels
10.4.1 EC/pH Control- System will inject +/- depending on EC levels, auto-adjust to meet target levels.
Set limits for controller adjustments when levels are too high/low
Page 62 of 109 pages
Ex: If dosing channel 1 is set by the grower to inject 10 liter/m
3
, the controller auto adjust range is 5 to 15 liter/m
3 in order to meet the EC level.
10.4.2 EC/pH Control
EC/pH coarse tuning- when way off target, faster/stronger correction
EC/pH fine tuning- off target is low, slow/light correction
Control cycle- Delay time from fertilizer/Acid injection point to EC/pH sensors reading
EC/pH averaging- balanced reading from EC/pH sensors
Dose boost off delay- time clear water circulated through system after fertigation stops and venturi closes
