Common Solution
If the Raven console fails so that it is not able to control the boom valves, and control valve, the
following procedures should be adhered to:
1.Disconnect console from console cable.
2.Disconnect console cable from power source (i.e. battery).
3.Remove the plunger and spring from the solenoids. (This will open the boom valves)
To start and stop spraying through the nozzles, start and stop the pump.
NOTE: Care should be taken because there is no agitation while the nozzles are not spraying.
For base model sprayers:
• Adjust the manual pressure relief valve to alter the spraying pressure to the desired pressure
as shown by the pressure gauge on the sprayer. If the desired spraying pressure is not able to
be achieved, alter the pressure relief valve setting so as to achieve the desired pressure (i.e.
alter the adjusting stem).
For sprayers fitted with a dual boom:
• Remove electric motor from three way fast close valve, and manually rotate valve until desired
spraying pressure is achieved.
• Drive the sprayer at a constant speed (as measured by the tractor) in order to apply the
required application volume as determined by the nozzle selection chart.
The sprayer should then be able to be operated in order to empty the tank. Once the sprayer
is empty of chemical, partially fill the tank with fresh water (no chemical) so that testing can be
performed in order to correct the problem. Repair or replace the console as soon as possible.
