Introduction
Basic Troubleshooting
Techniques
When troubleshooting, refer to the system schematics and determine the
components that are critical to the process. Test each of the critical
components to determine the problem. Also, consider how the RGU’s
programming parameters may be affecting the situation. Consider
upgrading to the latest version of firmware available.
When a damaged component has been found, always try to determine the
cause of the problem, rather than just replacing the component. Verify that
equipment is connected and being used properly; verify that the parameters
are properly set for the particular application; and so on. Try to determine
and resolve all underlying problems to avoid future component failures.
For significant or recurring problems, contact your local Rockwell
Automation office for support. Rockwell Automation support personnel
can provide technical assistance and can offer information about hardware
and software updates as they are made available.
Data Nameplates
The data nameplate provides the electrical ratings for the RGU, signifies the
type of RGU, and identifies the options that have been included in the unit.
The data nameplate shown in Figure 1.2 is located in the input bay of the
RGU and signifies the unit ratings, catalog string, and unique reference
identifiers for the RGU.
