Notice that :
Combining valves into temporary groups by “&” symbol can be done only
when the valves belong to the same irrigation line. The valves of the
temporary group will share the same water and fertilizer dosage.
Constant Groups (G1, G2…) cannot be combined by “&” or “+”.
Valves combined by “+” will start together at the same time but each
valve will have its own water dosage. As for fertilization, if the valves are
of the same line, they will share the same local fertilizer dosage and if
there is central fertilization, then the fertilizer dosage will be common to
all the valves combined by “+”.
The sequence defined at the local
MMI
of the
DREAM 2
may contain 28
members at the most. However longer sequences can be defined through
the
CONSOLE
or the
SPOT
, but then they will not be editable through
the local
MMI
.
Using long sequences must be enabled at the
DEALERS
DEFINITIONS
.
2.2
The Water Dosage definition
Each member of the sequence must have a water dosage defined in order to be able
to irrigate. In the dosage definition screen the sequence members are arranged in a
vertical order, the movement to the next or former member is done by the PAGE UP
(
) and PAGE DOWN (
) keys.
The dosage definition process starts with the selection of the dosage mode. For
selection of the water dosage mode place the cursor at the dosage units field. The
following dosage modes are supported:
hh:mm:ss
– by time
m3
– by volume
m3/area
– by volume of water per each unit of area
evaporation
– by volume calculated from the accumulated evaporation
since last irrigation
evaporation time
– The volume calculated from the accumulated evaporation
is divided by the nominal flow to obtain the needed
irrigation time.
by volume by time by evaporation
