inaccurate AccuFlow
measurements (i.e. console
indicate more product applies
than actual product removed
from tank.
1. Refer to Figure 2, “System Capacity Chart,” on page 46 or Figure 5,
“System Capacity Chart,” on page 57 to verify that the target application
speed is below the maximum speed allowed for the implement width
and the target rate.
a. If the maximum speed is exceeded, reduce the application speed
especially if actual rate & pressures are unstable.
b. If the application speed is within allowable range, skip to step 3.
2. Refer to the stem diagrams in and verify that the AccuFlow system is
plumbed correctly. If the system is plumbed correctly, proceed to step 3.
3. Verify that the difference between the static and operating pressures do
not exceed 5 PSI. If the pressure difference:
a. Is greater than 5 PSI, proceed to step 4.
NOTE: Bleed the system before performing maintenance and service
(see “Discharging the AccuFlow™ System” section on page 61).
4. The following maintenance and service steps should be:
a. Clean the strainer located next to the Vortex cooler. Check hoses
for deterioration and replace if necessary.
b. Remove all excess hose length between the nurse tank and break-
away coupler typically 12 feet).
c. Remove excess hose between the break-away coupler and the
AccuFlow system (typically 3 feet).
d. Verify that the break-away coupler is 1-1/2”, not 1”. If the break-away
coupler is the correct size, proceed to step 5.
e. Verify flow through the Vortex cooler chamber by:
•
Removing the vapor hoses from the steel vapor tubes at
applicator knives.
•
Secure hose ends so each hose can be viewed from the
vehicle cab.
•
Operate vehicle and AccuFlow system for a short period (30
seconds max) in the field into the wind.
•
Verify a heavy stream of anhydrous ammonia vapor is
discharged from each hose end. If not, disassemble and
clean the Vortex cooler. Refer to Maintaining the Vortex
Cooler section on page 65 for detailed instructions on
disassembling the Vortex cooler.
Console does not power-up or
no indicators are lit to verify
system power-up.
1. Check fuses either on the back of the console or on the console’s cable.
Refer to the console Operation manual for assistance.
2. Check power and ground connections to the battery. Verify that the
power leads from the console cable are connected directly to the
battery, not chassis ground or another power source.
3. Check operation of the master switch.
4. Verify power at valve connectors.
5. If none of the above steps resolve the issue, the console may require
repair. Contact a local Raven dealer for further assistance.
