Irrigation Timing
In order for a program to be started at a desired time, it must have a start time and
the days of operation defined. Such a program will be considered SCHEDULED. The
scheduling is done by the following screen:
The days on which the irrigation will take place, can be specified either by defining a
nonzero cycle of days or by setting up a “Run-List”. The length of the “Run-List” can
go up to 16 days, the user can mark each day with a letter that represents the
desired activity of the specific day:
(f)
indicates fertigation,
(w)
indicates water only
(
-
)
indicates no activity and
(s)
indicates single time activation the program will be
executed only once on that day (but including both irrigation and fertilization).
Notice that:
The desired irrigation days can be specified only in one of the two possible
ways, therefore when the cycle of days is nonzero; the "Run-List" disappears.
Defining the stop time is optional. When defined, it can be used in two ways:
1. By default it defines the time that when it arrives, the program is
terminated.
2. The second option depends on a selection made at the
DEALERS
DEFINITIONS
and then, the stop time actually defines the maximal duration
of the program.

Cyclic irrigation
The lower part of the
Irrigation Timing
screen deals with
Cyclic irrigation
. If a
program has to be repeated several times a day, usually the numbers of cycles and
the interval between the cycles will be defined. The interval is measured from
beginning of the first cycle to beginning of the next cycle. When the interval between
the cycles is 0, the second cycle starts right after termination of the previous cycle.
