Check the Indicators
The indicators show individual I/O status (yellow) for each point and
a bi-colored LED for module "OK" (red/green).
During power up, an indicator test is done and the following occurs:
• The "OK" indicator turns red for 1 second and then turns to
flashing green if it has passed the self-test.
• The I/O status indicators turn ON for a maximum of 2 seconds
and then turn OFF.
This completes installation of the module. Use the information below
to remove the module.
