Flow Control Mechanism
The flow control mechanism allows the controller to discover flow deviation. When discovered, the
controller performs one of the following according to the definitions:
Stops irrigation and issues an alarm.
Continues irrigation and issues an alarm.
Ignores flow deviation.
Flow control is only possible for valves that have a water meter defined. It is also carried out when
the water unit is Time. At the beginning of irrigation a parameter Fill Delay is active. This delay can
be according to time or M3. During Fill Delay the flow deviation is ignored.
The following are the required steps for operating flow control:
1. Define the following parameters in the System Setup menu:
Fill Delay M3 - The amount of water in M3 that irrigate in the beginning of irrigation during
which flow control is ignored.
Fil Delay-Mins - The amount of time during which flow control is ignored.
Flow Dev Unit - The units in which the flow control is detected.
Flow Delay Unit - The units Mins or M3 by which the flow control delay is measured.
2. In the Valve Water & Fert menu define for each valve the following parameters:
Water Flow M3/H - Enter the nominal flow rate of the valve.
Under Flow Deviation - Enter the allowed deviation below the nominal flow (according to the
units % or M3/H as defined in the system setup).
Under Flow Reaction - The controller’s reaction to this type of fault.
Over Flow Deviation - See underflow.
Over Flow Reaction - See underflow reaction.
Flow Fault Delay - According to the unit Minutes or M3 as defined in the system setup.
Additional information is found in the appropriate table.
Water Multiplication
The controller enables increasing or decreasing the water amounts without changing the amounts in
the valves. The change can be permanent or only for today. The change is performed by percentage
of the program amount (0-200%). 0% and 100% means no change.
Permanent Multiplication of Water for all of the Valves in the system
Enter the System Setup menu and move down to the Fixed Water Multiplication row and change
the % accordingly.
A message about water multiplication appears in the following menus:
