Initial Set Up and Navigation
Vehicle Heading and Speed
The Viper Pro displays the current GPS course over ground, in compass degrees, and the reported speed from
a ground speed sensor or GPS receiver.
Note:
A heading of 000° indicates magnetic north.
The Viper Pro speed display indicates both the detected vehicle speed as well as the source and use of the
displayed speed.
If ‘CAN’ is displayed in the speed area, the Viper Pro is registering speed from the Raven CANbus control
system. The Viper Pro is also using the displayed speed value for speed compensated product rate control.
If ‘GPS’ is displayed in the speed area, the Viper Pro is monitoring speed from a GPS receiver (e.g. an Invicta
or Phoenix series receiver). ‘GPS’ will be displayed when the Viper Pro is connected to an optional Raven
serial control console. In this instance, the speed displayed on the Viper Pro is for reference only and is not
used to adjust product rate. Verify that the speed reading on the serial controller is accurate.
Review the Speed Sensor Type and Cal section on page 31 if the speed reported by the Viper Pro does not
approximate the actual vehicle speed.
Fan RPM
The monitored fan RPM is displayed on the Main screen.
Review the Fan Cal section on page 38 for information on calibrating and setting options for the fan RPM
display.
Pressure Display
Note:
Pressure readings are displayed for operator display only and do not affect product rate control.
The ‘P2’ value is currently not used.
The pressure of a liquid product control node may be displayed on the Viper Pro. During an active job, the
pressure of either product 4 or product 5 may be monitored in the pressure display on the main screen.
The Viper Pro will display:
• All dashes if no pressure transducer is detected by the the product node.
• CAL if a pressure transducer is detected but has not been calibrated.
Refer to the Pressure Transducer section on page 245 for details on calibrating the pressure displays on the
Viper Pro.
