GENERAL TROUBLESHOOTING
Problem Action
Adjacent nozzle control valves pulsing at
same time.
• Check cabling connections.
• Check nozzle diagnostics and DTC list for nozzle control valve
errors.
• Restart the calibration wizard to reindex the nozzle control
valves across the implement width.
• Contact a local Raven dealer for additional assistance.
Rate reads “0.” • Verify SPEED is registering accurately. If SPEED is zero, refer to
the VT display troubleshooting procedure.
• Verify TOTAL VOLUME is registering flow. If not, refer to
problem .
Rate inaccurate or unstable. • Verify that all calibration numbers and settings keyed into the
console are correct. Verify SPEED is registering accurately. If
SPEED is inaccurate, refer to the VT display troubleshooting
procedure.
• In MAN (manual) operation, verify that RATE display holds
constant.
• Confirm that boom section status shown on the display is not
changing.
• In MAN (manual) operation, check low end and high end
pressure range.
• In the Product Control Settings, adjust the Response Rate and/
or Deadband value(s) to stabilize the system.
Cannot verify rate in automatic or manual
operation.
• Check cabling to motorized control valve for breaks.
• Check connections in cabling for cleanliness.
• Verify that there is voltage at the valve connector by toggling
master switch on and setting the system to manual. Manually
operate enter a pump PWM to verify voltage.
• Verify that valve is turning, if not, replace control valve.
Sprayer pressure is correct but RATE is low. • Verify that nozzle strainer screens or check valves are not
plugged.
• Verify that pressure at each boom is the same.
• Verify all nozzles are of proper and same orifice size.
Total volume does not register. • Check flow meter/encoder cable for breaks and shorts. See the
Flow Meter with Deutsch DTM Connector section on page 99.
• Check the internal components of the flow meter/encoder;
clean and adjust. Appendix D, Maintenance Schedule and
Replacement Parts for flow meter cleaning and adjustments.
• Replace flow meter transducer/encoder.
Total volume registers flow inaccurately. • Verify that arrow on flow meter is pointing in direction of flow.
Boom valve(s) will not operate. • Check cable for wires with breaks.
• Check connectors for cleanliness.
• Check BOOM switch and MASTER switch for operation.
• Replace boom valves.
