Color Description
Red When the LED is off, it signals that the –48 VDC output voltage are
within the normal operating range. Output voltage between the
minimum and maximum limits will not create an output fail alarm,
and output voltages below the minimum or above the maximum will
create an Output Fail alarm.
Led illuminates red to indicate that the –48 VDC output is out of the
specified range.
When you turn the power supply on, the red LED illuminates for two
to three seconds to test LED operation before going off.
