NETAFLEX™ 3G INSTALLATION MANUAL 21
SYSTEM OPERATION
Measure the EC and pH control cycle
• EC and pH control cycle is the time elapsed from the start of fertilizer or acid injection until the change
starts to be recorded by the EC and pH transmitter (usually 4-10 sec.).
To measure the NetaFlex™ 3G control cycle for pH*:
Run the NetaFlex™ 3G with fresh water only until the pH value stabilizes on the transmitter's display
(Deviation not greater than +0.1 -0.1).
Manually open the acid dosing channel and simultaneously start a timer.
Observe the pH value on the transmitter's display, as soon as it first reacts stop the timer.
We recommend to repeat the 3 previous steps 3 times and calculate the average time.
Enter the data into the controller (NMC Pro - screen 7.7) .
Stop the program.
*Time aplicable for EC and pH control cycle.
ATTENTION
Restore the settings of all the alarms back to the state where adequate
protection to the system and the crop is provided (see the Controller Manual).
If there is any problem during the process, see Troubleshooting in the NetaFlex™ 3G User Manual.
