The machine can be fitted with 16 no le sections.
This will require Raven RCM control. The solenoid
valves are, electrically, turned on and off to control
the flow of air to the no les.
For troubleshooting purposes or in the event of
an electrical problem, the solenoid valve can be
manually overridden.
Remove the black plug from the white box in the
position above the valve that is to be overridden.
Insert a flat head screw driver in through the top
of the box and find the screw in the top of the
solenoid valve. Push down on the screw driver and
turn the screw a 1/4 turn in either direction.
The valve should now be allowing air to flow out to
the no le and if there is fluid in the lines, it should
be coming out of the nozzle.
To shut off the valve , turn the screw driver 1/4 turn
in the opposite direction to when it was overridden.
The screw in the top of the solenoid is spring
loaded, it will pop up when returned to its original
position and shut off the flow of air.
On the solenoid bank there are two exhaust ports.
These must be kept clean so that the air can expel
from these when the RapidFire nozzles are turned
off.
Prairie Pro Operator's Manual MY19 - REV 2
If these ports are blocked the air can not release
from the air checks, through the solenoids to
atmosphere and the nozzles will continue to spray.
The ports can become blocked when working in
dusty environments. To clean the exhaust ports,
remove them from the air solenoid manifold and
rinse them in solvent. Blow out with compressed air
and refit.
If a section of the boom will not turn on, it may be
because that section has a large air leak, in the supply
air to the check valves on the no les. To find the air
leak, spray soapy water on each of the connections
along that section. Replace any component that is
leaking air. If the air leak can not be found on the
section of the boom line, check to see if the air is
leaking out of the air solenoid manifold exhaust port.
These should not leak air when the boom sections
are turned ON. If they do then a solenoid is stuck.
To find the stuck solenoid turn all the boom sections
OFF. Remove the hoses from the under side of the
air solenoid manifold.
Exhaust port;
one located on
each end of the
manifold.
