Correction of second EC sensor -0.5 - 0.5 mS/cm
This correction value will be added to the measured value in order to correct a static
deviation.
Alarm delay of second EC sensor
The length of time that the EC sensor alarm will be delayed.
Enter value 00:00:00 to disable the alarm.
Third EC sensor
Select the function of the third EC sensor.
None: Disabled. No second EC sensor present.
Monitor: To monitor the measurements of the control EC sensor.
Pre-measurement: To measure the EC value of the supply water.
Pre-blending: To measure the EC value during the pre-blending process (i.e. the
blending of fresh water with drain water).
Correction of third EC sensor -0.5 - 0.5 mS/cm
This correction value will be added to the measured value in order to correct a static
deviation.
Alarm delay of third EC sensor
The length of time that the EC sensor alarm will be delayed.
Enter value 00:00:00 to disable the alarm.
Minimum control pulse of pre-blending EC 0.4 - 4 sec.
The minimum number of seconds that the mixer valve or dosage valve must remain
open.
Enter the lowest possible value.
This setting also determines after how many seconds the valve may reopen (called
the 'cycle time’).
Cycle time = 10 x Minimum control pulse. The maximum cycle time is 10 sec.
If a large value is set for Minimum control pulse, fertilizers will be dosed in
long pulses less frequently. If a small value is set, fertilizers will be dosed in
short pulses more frequently.
If the pulse time drops below the 'Minimum control pulse', this duration will
be added to the next control pulse. Try to avoid this.
EC dosage valve with pump
Enables you to activate a system whose dosing pump is continuously actuated during
irrigation using dosage valves.
