Chapter 318 SCS 4000/5000 Series Installation & Operation ManualProgramming CANbus NodesThe CAN nodes are programmed using the SCS console in Edit mode.See Chapter 5, Initial Startup & Console Programming, for information on programming CAN product nodes.Refer to the AutoBoom™ Calibration & Operation manual for detailed operation of the optional AutoBoom™system with your SCS 4000/5000 Series console.CAN TroubleshootingAlthough the control algorithm is located within the CAN node, all of the same troubleshooting techniques thatare used in a traditional hard-wired system still apply to a CAN system and the behavior of the system remainsthe same. Flow and speed sensors, as well as the control valve and boom valves, are used in the samefashion.CAN Node Off-line ErrorsThe most likely causes for losing CAN communication between the console and any one of the nodes are:1. Corroded and/or open connections in the circuit.2. Console and/or CAN node logic power and grounds connected to a “dirty” power source (dirty power isdefined as any circuit with a variable load that exceeds 1 ampere). This is especially true of circuits loadedby electrical coils.3. Console and/or nodes connected to different power and/or ground sources. This can result in componentsoperating at different voltage planes.
