SYSTEM CONFIGURATION PROCEDURE
7.8 Drainage Configuration
• Ratio: Define volume per pulse of the drainage meters (liter/pulse or gallon/pulse).
• On Delay: Define how long a valve, which is configured to this drainage measurement, should be open before
the measured drainage is related to this valve. All drainage measured before this time has elapsed (although
the valve is open) will still be related to the previous opened valve that was configured to this drainage sump.
• Off Delay: Define how long after irrigation has finished, the measured drainage should still be related to the
previous irrigation. This value is used to “tell” the NMC when to stop relating drainage to the previous irrigation
and write it to all relevant history tables.
7.9 EC/pH Configuration
Define the range of the EC/pH transmitters.
• Default settings for Netafim EC/pH transmitters is:
EC: zero to 10 mS
PH: zero to 14 ppm
• EC Control Sensor: Define which EC sensor should be used for control. When setting EC 1 + EC 2, EC1 will
be used for control, and EC2 will be used for verification.
• pH Control Sensor: Define which pH sensor should be used for control. When setting pH 1 + pH 2, pH1 will be
used for control, and pH2 will be used for verification.
