Multi Pro 5800Page 8 − 10GeoLink Spray System
When the spray pump is ON, the switch light is illuminat-
ed, the spray pump icon appears on the InfoCenter dis-
play. Selecting and adjusting the application rate is
handled through the X25 or X30 controller. The ASC−10
adjusts the electrical current to the spray pump hy-
draulic proportional valve solenoid coil. Higher current
(rate increase) to the solenoid coil increases hydraulic
flow to the spray pump motor and results in a higher
spray pump speed and more output/pressure. Lower
current (rate decrease) to the solenoid coil decreases
hydraulic flow to the spray pump motor and results in a
lower spray pump speed and less output/pressure. The
spray nozzles achieve their rated output at 40 psi (2.8
bar) unless otherwise stated. The application rate and
nozzle selected will dictate the exact pressure. See the
Spray Nozzle Selection Guide (Toro12−082−T) for infor-
mation regarding spray nozzle selection.
Agitation circuit
When the agitation switch is ON, the switch light is illumi-
nated, the agitation icon appears on the InfoCenter dis-
play and the agitation control valve is opened. This open
valve directs spray system flow to four (4) agitation
nozzles on the left side of the spray tank. The agitation
nozzles direct spray product back into the lower portion
of the tank to agitate or stir the contents of the tank.
When the agitation switch is OFF, the agitation control
valve is closed so no flow is directed to the tank agitation
nozzles. The agitation valve includes an LED to indicate
the current valve position (red = closed, green = open).
A manually adjustable agitation bypass valve is incorpo-
rated into the agitation control valve. Proper adjustment
of the agitation bypass valve prevents system pressure
changes when the agitation valve is switched ON/OFF
while spraying. Flow from the agitation bypass valve is
directed back to the spray tank (agitation bypass).
A manually adjustable agitation throttle valve restricts
the flow to the agitation nozzles. The valve allows con-
trolling the spray system pressure at the agitation noz-
zles when larger application rates are used.
Spray boom circuit (nozzle circuit)
The system includes an in−line flow meter to measure
actual spray product flow to the nozzle valves. The flow
meter is positioned directly before the nozzle control
valves.
There are 10 nozzle valves used to control the 12 spray
nozzles on the Multi−Pro 5800 GeoLink spray system.
The nozzles on the left and right booms are controlled
individually (a nozzle valve for each nozzle). The
nozzles on the center boon are controlled in pairs (a
nozzle valve controls two nozzles)
The ASC−10 controller controls the nozzle valves. An
open nozzle valve directs spray product flow to the spray
nozzle(s). When a nozzle valve is closed, no spray prod-
uct flow is available to that spray nozzle(s). Each nozzle
valve includes an LED to indicate the current valve posi-
tion (red = closed, green = open).
