4. Advanced Operation
• Operation Setup *:
The options are:
o
N.Active:
o
Automat:
The normal selection.
o
Clos+Al:
The main valve is closed manually. Irrigation cannot be carried out. An alarm is issued.
o
Open+Al :
The main valve is opened manually. An alarm is issued.
o
Close:
the main valve is closed manually. Alarm is not issued.
o
Open:
The main valve is opened manually. Alarm is not issued.
o
Protect:
The main valve is opened manually. Alarm is issued and the line is paused if there is a fault.
• .Irrig. by Queue (Yes/No) *:
If “Yes” then two sequences cannot work at the same time. The
operation is according to the “priority” rules.
Head General Constants (161):
Press “H.Gnrl Const.” in the “Head Constants – 16” to access:
Screen Explanation:
(Programmable screen)
• Limit Flow M3/Hr (GPM):
It is possible to define a limit flow rate that is compared with the total
nominal flow rate of all of the valves working. When a new irrigation program “wants” to start irrigating
it “looks” at this parameter minus the working valves nominal flow rate and calculates whether its own
nominal flow rate can fit in. If it is greater, then the program waits until there is enough volume available.
• Fill Delay – Mnt:
At the start of irrigation the pipelines are still empty thus the flow rate is very
high. In order to prevent false faults the overflow setting must be ignored during this time. Enter the
number of minutes required.
• Fill Delay M3 (Gallon):
See the previous item. Enter the number of cubic meters (gallons) to be ignored.
