About the Indicators
The diagnostic modules have indicators that let you check the module health and
operational status. The following status can be checked with the indicators.
• Channel I/O Status - This indicator displays the ON/OFF state of the
input channel, and channel wiring fault conditions:
– Off indicates that the channel is off with no faults.
– Yellow indicates that the channel is on with no faults.
– Red indicates either a channel open or short condition.
• Module Fault Status- This indictor turns red for any individual
input/output channel open, short, or module reverse power conditions.
With no fault, the module fault status indicator turns off.
