4. Advanced Operation
Fertilizer Pump Setup (1423):
Press “F. Pump Const.” in the “Ferilizer Pump Status – 142”
screen to access the “Fert. Pump Status - 1423” screen.
Screen Explanation:
•
Fert. Pump Type *:
The options are:
o
N.Active:
o
Electron:
(Electronic) a type of fertilizer pump that is a piston pump operated by pulses
sent from the controller.
o
Electric:
Usually an electric centrifugal fertilizer pump that the controller starts at the
beginning of fertilization and stops at the end of fertilization.
o
Venturi:
A type of fertilizer pump that consists of a Venturi pipe and a solenoid. The
controller controls the solenoid.
o
By Pulse:
A fertilizer pump equipped with a fertilizer meter that works according to pulse
measurement and the ratio of pulses between water and fertilizer as opposed to all of the other
pump types that are time based.
o
Fert. Type *:
The options are:
Not Def, EC, pH, OH
– the OH is the same mechanism as
pH but works in the opposite direction. The
Fert. Type
parameter defines the group that the
fertilizer pump belongs to. Each group is controlled separately in the EC/pH correction.
•
Fert. Flow Ltr/h (GPH):
The nominal flow rate of the fertilizer pump. When working with a time
based fertilizer pump the operation of the fertilization is according to this parameter.
•
Pls.Duration-Sec:
When working with time based proportional fertilization the controller
calculates the working time and wait time according to this parameter.
