SECTION 2
System Description
2-11
Distance Based Program Mode
Vehicle speed input is
acquired from the MEGA
provided GPS system that
relays the vehicle speed to the
controller. The controller will
calculate the distance to
signal the rear spray heads
when to turn ON and OFF creating an alternating
pattern (checker boarding). This mode can reduce
water consumption and control dust while
allowing 1 steer tire and 1 drive tire to remain on a
dry surface when efficiently set. This mode can be
adjusted to spray water most of full width of a haul
road in a single pass without crossing the center
line. It can produce a wide pattern that can carry
over into an adjacent lane when the spray head
angles are properly adjusted.

Using ‘WET +’ and WET -’ function buttons the
operator can adjust the wet coverage distance in

Distance based programming will control only the
four (4) rear spray heads, all other functions will
remain in manual selection mode. All other
functions can be activated manually while in
Distance Based Programming Mode but will not be
controlled by the distance based settings. Distance
based programming will turn the selected spray
heads ON/OFF at the selected distance intervals.
Pause and Low Water protection are functional in
this mode. All selected spray heads OFF at 4.8 KPH
(3 MPH) or less.
