3.3 LEDs

3.3.1 START LED (START: Red)

This LED is turned on or off when the transfer switch (START/STOP) is pressed.

3.3.2 Power LED (POWER: Green)

This LED is on while the user system power supply VIN (Vcc: 2.7 V to 5.25 V, PVcc: 2.7 V to

5.25 V) or the power supply Vcc (5 V ± 5%) dedicated to the adapter board is supplied.
