Description
When the LED is off, it signals
that the +24 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.
When you turn the power
supply on, the red LED
illuminates for two to three
seconds to test LED operation
before going off.
LED illuminates green to signal
that voltage is > or = to 20VDC
at turn-on and down to
19.0VDC (+/- 0.5 V tolerance).
The LED illuminates amber
when the input voltage is active
down to 16.0VDC and indicates
that there is still a voltage
present (voltage on the terminal
block). The LED remains amber
and is active to around 10 V.
The LED can be OFF below
15.8VDC.
The LED illuminates s green
when all fans are operational.
The LED illuminates red when
a fan failure is detected.
