• EC Control – define whether EC control should be operative.
• pH Control – define whether pH control should be operative.
• Minimum On Time (sec) – define the minimum time the dosing regulator may be
opened for. This feature is used to protect the regulator for excessively being
turned on and off. The minimum allowed On time is 0.8 seconds.
• Minimum Off Time - define the minimum time the dosing regulator may be turned
off for. This feature is used to protect the regulator for excessively being turned on
and off.
• Coarse Tuning (1-Slow, 10-Fast) - Coarse tuning is used to adjust speed and
aggressiveness of EC/pH control. A higher value will result in faster correction but
might lead to over shutting (see
EC/pH correction adjustment for further
information).
• Fine Tuning (1-Slow, 10-Fast) - Fine-tuning is used to fine tune EC/pH control
(see
EC/pH correction adjustment for further information).
• Control Cycle (sec) – define the control cycle for EC/pH control. This should be
the time it takes the system since it injected fertilizer / acid until the change in
recognized by the system.
• EC pH Averaging (0-Low, 20-High) - averaging factor for EC/pH measurement.
EC/pH averaging should be used to enable correction when injection is not
homogonous.
