End Gun Arc Setting Example
An end gun is installed at the end of the machine and
is used to increase the area irrigated beyond the end
of the machine. See Figure 79-1.
The end gun must be set to cover a specified area to
ensure the best uniformity. This area is determined
by two angles – the Forward and Backward end gun
angles which are sometimes referred to as the end
gun arc settings.
A line on the sprinkler chart specifies the correct end
gun arc settings for the machine: See Figure 79-2.
END GUN ARC SETTING EXAMPLE:
FORWARD ANGLE = 45
BACKWARD ANGLE = 85
IMPORTANT: This is an example only. Refer to the
sprinkler chart for each pivot to determine the correct
end gun arc settings. These settings should initially
be set by your Valley Dealer at time of installation
and start up.
