Description
5V PWR
Green
+5 V power output LED
Green: +5 V power output is normal.
Off: +5 V power output is off.
5V ALM
Red
+5 V power alarm LED
Red: +5 V power output is off or the voltage is abnormal.
Off: +5 V voltage is normal.
Vin
Green
Power input LED
Green: input power has voltage.
Off: input power has no voltage or there is positive/negative
error.
Min
Yellow
Input voltage hierarchical alarm LED
Yellow: the deviation between the input voltage and the
centered voltage is within range 1.
Off: the deviation between the input voltage and the centered
voltage is beyond range 1.
Maj
Red
Input voltage hierarchical alarm LED
Red: the deviation between the input voltage and the centered
voltage is within range 2.
Off: the deviation between the input voltage and the centered
voltage is beyond range 2.
Cri
Red
Input voltage hierarchical alarm LED
Red: the deviation between the input voltage and the centered
voltage is within range 3.
Off: the deviation between the input voltage and the centered
voltage is beyond range 3.
You can set range 1, range 2, and range 3 but they must be between -36 V and
-72 V.
If input voltage hierarchical alarm LED is yellow or red, the input voltage is
within the allowed range.
