SCS 4000/5000 Series Installation & Operation Manual
Programming CANbus Nodes
The CAN nodes are programmed using the SCS console in Edit mode.
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 Troubleshooting
Although the control algorithm is located within the CAN node, all of the same troubleshooting techniques that
are used in a traditional hard-wired system still apply to a CAN system and 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.
CAN Node Off-line Errors
The 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 is
defined as any circuit with a variable load that exceeds 1 ampere). This is especially true of circuits loaded
by electrical coils.
3.
Console and/or nodes connected to different power and/or ground sources. This can result in components
operating at different voltage planes.
