Description Color LED LED Label
When the LED is off, it signals
that the +24 VDC output
voltage is within the normal
operating range. Output voltage
between the minimum limit and
maximum limit will not create
an output fail alarm, but output
voltages below the minimum
limit or above the maximum
limit will create an Output Fail
alarm.
When you turn the power
supply on, LED turns red for
two to three seconds to test the
LED operation before going off.
Red Power supply activity OUTPUT FAIL
The LED turns green to signal
that voltage is > or = to 20 VDC
at turn-on and the voltage
reduces to 19.0VDC (+/- 0.5 V
tolerance). Green A bicolor LED indicates the
presence of input voltage INPUT OK
The LED turns to amber when
the input voltage is active and
is reduced to 16.0 VDC and
indicates that a voltage on the
terminal block is still present.
The LED remains amber and is
active until around 10 V. The
LED should be OFF below 15.8
VDC. Amber
The LED turns to green when
all fans are operational. Green A bicolor LED indicates the
power supply fan status FAN OK
The LED turns to red when a
fan failure is detected. Red
