7.2.2.1. Power Button

The power button (Fig. 19,

Fig. 20, pos. 7, and Fig. 22, pos. 1) allows to power ON/OFF the system.

Even when the system is turned off via the power button there is still a standby-voltage of 5 V on the

SBC. The system is not completely disconnected from the main power supply by turning off via the

power button.

Hints for DC power connection:

The DC main power supply should be able to be switched off and on via a 2-pole isolating switch.

The unit is only completely disconnected from the DC main power supply, when the DC power cord is

disco

nnected either from the DC main or the unit. Therefore, the DC power cord and its connectors must

always remain easily accessible.

7.2.2.2. Power LED

The power LED (

Fig. 22, pos. 4) indicates the current system power state (S0, S3, S4, or S5) as shown in shown in Fig. 23.

The power LED will blink red if an error condition was detected (the system is held off). The color red is reserved for error

codes, only.

An over-temperature condition has the highest of all priorities. The power button is deactivated as long as the temperature

is too high. To signalize this emergency state, the LED lights up red.
