Chapter 6 Service and Maintenance
Schedule Codes Explanation
The codes that are listed in this table are used to identify the task that is
associated with the components that are identified in the tables on page 87
and
page 88
.
Recommended Maintenance Tasks and Schedule
Code Task Description
IInspect
Inspect the component for signs of excessive accumulation of dust, dirt, or external damage.
For example, inspect the fan inlets for debris that can block the airflow path.
C Clean Clean the components that can be reused, specifically fan inlets and heatsinks.
M Maintain This type of maintenance task can include tightening loose terminal and cable connectors.
RReplace
This component has reached its mean operational life. Replace the component to decrease
the chance of failure. It is likely that components can exceed their designed life, but
component life is dependent on many factors such as usage and heat.
Use the predictive maintenance objects to determine a replacement schedule for
components in shaded table rows.
Rv Review
A discussion with Rockwell Automation personnel is recommended to help determine whether
any enhancements that have been made to the hardware could benefit the application.
