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, as well as channel wiring fault conditions:
– Off indicates the channel is off with no faults.
– Yellow indicates 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.
Where:
1 = Channel bicolor Status indicator
2 = Insertable label for writing individual input/output designations
3 = Module bicolor Fault Indicator
