VSX OPERATING MANUAL
Blocks: A Block is a group of more than one
station (up to 8 per block) which will activate
all at once, which are given a single run time,
and which may be included in a sequence just
like a single station. A Block counts as a single
Event regardless of how many stations are
assigned to it. It is technically possible to create
a Block of only 1 station, but this defeats the
purpose of this feature.
When multiple stations are activated in a Block,
they are actually staggered at 1-second intervals
to prevent the simultaneous electrical inrush
draw of all the solenoids.
Blocks may be used to help you in several
ways. They allow you to program and adjust
large numbers of sprinklers with fewer key-
strokes, since many sprinklers of similar types
will have identical run times.
If you group similar sprinklers with similar
flow capacities into Blocks, you can have a
fairly constant level of flow, even for a large
number of sequencing Events.
By permitting Blocks to sequence (simultaneous
groups of 4 sprinklers down a fairway,
for example), large areas can be irrigated with
fewer Programs and less complicated sequences.
Blocks can also irrigate more efficiently than
single stations, because the “cloud” of spray
from multiple sprinklers running simulta-
neously cools hot surfaces, and reduces the
evaporation of individual sprinkler
applications.
Blocks may also be included in Preset
programs, and can be used to “syringe”
greens and other areas more efficiently and
quickly, while the course is in play. One or
two Blocks can wet an entire green in a
single run time or two.
Creating Blocks:
Blocks are created, edited, or deleted at the
Field Controller Option level. Each Field
Controller may have up to 64 Blocks, which
are always the same, regardless of which
Programs they are included in.
With no programs selected, from the basic
time date display on the controller, press the
OPTIONS button approximately 4 times
until the display shows:
Press ENTER. The display will show:
