Troubleshooting the Sequence of
Events Module
What This Chapter
Contains
This chapter describes how to troubleshoot the Sequence of
Events module.
Using LED Status
Indicators
Your Sequence of Events module has yellow indicators that show
individual I/O state and a bi-colored (red/green) indicator that
shows module status with an “OK”. Status indicators are located on
the front of the module. The LED status indicators used on the
Sequence of Events module are shown in Figure 8.1.
Figure 8.1
During power up, an indicator test is done and the following occurs:
"OK" indicator turns red for 1 second and then turns to flashing
green if it has passed the self-test.
I/O status indicators turn ON for a maximum of 2 seconds and
then turn OFF.
