Maintenance
Cleaning a CAI/SAI Marshalled Termination Assembly involves careful brushing and vacuuming to
remove accumulated dust and dirt harboring chemical particulate that can accelerate terminal or connector
contact corrosion. When cleaning the termination hardware area, be careful not to disturb the wiring.
Electrical shock hazard. Remove power from all involved wires and terminals.

3.4 Troubleshooting

A module's operating status and errors are indicated by its status LEDs. Also, error codes and related
diagnostic messages are displayed by the 4-mation configuration software and the Diagnostic Logger
utility. Details of error codes and messages are available in the following documents:
•
4-mation Software Messages and Error Codes (document number CG39-21, located in binder
