NMC-64 Irrigation
• Nom. Flow - Displays the nominal/set flow rate (m³/h or gallon/h).
• Act. Flow - Displays the actual/measured flow rate (m³/h or gallon/h).
• EC/pH:
• Target - Desired value for the EC/pH.
• Actual - Measured EC/pH values.
• THE LOWER SECTION REFERS TO FERTILIZER ACTIVITY:
• Open (%) - Opening percentage of the fertilizer channel.
• Min (%) - Minimum allowed opening percentage.
• Prg (%) – calculated opening percentage of the channel.
• Max (%) – Maximum opening percentage of the channel.
The Prg. (%) and Min/Max (%) are calculated according to the fertilizer channel flow
rate, allowed deviation and actual/measured water flow rate.
When EC/pH control is active the Open (%) will change according to the difference
between the actual and the calculated EC/pH values.
If the Open (%) is close to the Min (%) or Max (%) it means that there is a big
deviation between the fertilizer program settings to the actual injection ratio. The Open
(%) cannot be higher than the Max(%) and cannot be lower than the Min (%), if it is
identical to one of them than the NMC-64 controller will not be able to reach desired
EC/pH values and the fertilizer program setting must be rechecked.
