CAN Troubleshooting
Although the control algorithm is located within the CAN node, all of the same troubleshooting techniques used
in a traditional hard-wired system still apply to a CAN system. CAN allows for modularization of the control
system, but the behavior of the system remains the same. Flow and speed sensors, as well as the control
valve and boom valves, are used in the same fashion.
Refer to the Raven CANbus Network Installation Manual for detailed troubleshooting procedures and
information.
