Valves Constants (133):
Press “Valves Constants” in the “Valves Status -13” screen to access
the “Valves Constants” screen.
Screen Explanation:
•
Valves Setup (N.Active, Active, Pause) *:
The same as in other elements (“Irrigation
Programs”,”Sequence”). Not active – resets all the temporary parameters such as accumulations
and the valve is not available. Pause – stops the valve but does not erase data.
•
Valve Type (Irrigat., CoValve) *:
Any valve can be defined in two ways: a normal valve which
is operated by an irrigation program, accumulates amounts of water and fertilizer etc., a “CoValve”
which only physically opens and closes together with the program but doesn’t accumulate. The
reason for this feature is to enable two programs to work simultaneously with the same valve. It can
be used when you want to apply a condition on certain programs by assigning them a “CoValve” and
making the condition on the “CoValve”.
•
Water Meter Number:
The number of the water meter that measures the amount of water
flowing through the valve. If the same water meter is assigned to more than one valve, the water is
divided between the valves according to the valves nominal flow rate.
•
Output slot/port:
Information only – cannot be edited. (To change the settings go to the “Technical
Menus - 6”.)
•
Flow M3/H (GPM):
The nominal flow rate of the valve. It is used by the controller: over/under flow
protection, water division between the valves, flow rate limiting of the “Head” etc.
•
Area Hectare (Acre):
The area that the valve irrigation system covers. It is used when the
“Irrigation Unit” is M3/Ha (THG/Acre). In this case the water quantity is the multiplication of the total
area of the valves by the parameter “Water Required” in the “Irrigation Program Programming - 122”.
