ACCUFLOW™ HP+ CALIBRATION AND OPERATION

3. Toggle the console to manual control mode.
4. Detect tractor hydraulic selective control valve (SCV) attached to the Raven control pump control valve circuit

to the continuous flow setting. Set the flow rate to provide maximum flow to the circuit. The HP+ control

system will control and limit flow to the boost pump.

5. Toggle the switch for section 1 (boom 1) on. If a multi-manifold system is in use, toggle all sections on. Toggle

any section switches not in use to their off positions.

6. With the master switch in the off position, drive at the target application speed to verify the speed readout on

the control console.

7. With applicator knives in the ground, toggle the master switch to the on position.
8. While driving at the target application speed, manually adjust the flow with the INC/DEC switch until the target

rate is achieved.

9. Set product 1 rate and start operation in Auto mode. Control node will operate both valve and pump as

required to achieve target rate.

10. System operating pressure at control valve will display as P1 and pump inlet (cooler) pressure will display as P2.
11. As daytime temperature and nurse tank pressure increases the tractor hydraulics can be turned off to save

power. An error message will be displayed if the control tries to use the boost pump and detects it is not

running.

FOR EXAMPLE:

Given an observed pressure reading 70 PSI and temperature reading 40° F. The point where these two readings

intersect is within the non-vapor area. See Figure 1, “Pressure vs. Temperature Chart,” on page 76.

12. If an additive such as N-Serve (Dow Chemical) or another nitrogen stabilizer is used with the system, periodic

cleaning of the AccuFlow flow meter may be required. Refer to Chapter 7,

Troubleshooting

, for instructions on

performing maintenance on the AccuFlow cooler or flow meter.

NOTE:

Due to the highly corrosive nature of many additives and nitrogen stabilizers, Raven recommends

injection of the additive after the Vortex cooler, control valve, and vapor lines. This will help prevent

corrosion of heat exchangers and other plumbing components. Corroded materials can cause system

components such as strainers, flowmeters, and orifices to become obstructed, and can decrease

service interval time and component life expectancy.
