Front Panel Indicators
The Front Panel of each I/O Power Supply Module supports three Light Emitting Diode (LED)
indicators detailed in the following sub-paragraphs
1.4.1.
Input Power Voltage Indicator
Each green INPUT POWER indicator is lit when the associated input (Input A, Input B) is
above the lower input voltage threshold.
1.4.2.
Output Power Display
The 10-segment LED indicator bar displays the approximate output current level percentage
(0 % - 100 %)
1.4.3.
Output Power Indicator
The DC Output indicator is lit when the I/O Power Supply Module's dc output is within
tolerance. Out-of-tolerance conditions, loss of input power or brown-out, and module
failures turn off this indicator.
