Figure 2.11: Location of Power P1 and P2
You can see the LED indicators to monitor power input situation. (Please
refer to Figure 2.13 for location of LED). If the voltage of power input
P1> 15 VDC, the P1 LED indicator will be enable (means the first power
input is used). It is the same for P2 LED indicator (to show if the voltage
of power input P2 > 15 VDC). When any voltage of P1 and P2 < 15VDC,
the Fault LED will be enable. It means that you don’t use redundancy
power input. When you have two power inputs, the system will use the
power inputs with higher voltage.
Note: UNO-3072Lprovides built-in examples to show how to monitor
power input status. Refer to console mode examples in C:\Program
Files\Advantech\UNO\UNO_IsaDIO\Examples\Console.
(Please install DI/O driver from the UNO CD to use these examples)
