The Health view contains information about battery status and controller temperature.

## Battery status

Controller > Hardware > Health

The Power Focus XCPower Focus XC battery serves as backup power for some system elements, such as the internal clock. The status of the battery is updated once a day, as well as at controller restart. When the battery is close to being completely depleted, a warning (3011) will be displayed. The battery shall be replaced as soon as possible when the warning pops up.

## Controller temperature

Controller > Hardware > Health

Controller temperature is monitored continuously by the Power Focus XCPower Focus XC. Supported temperature units are degrees Celsius (°C) and degrees Fahrenheit (°F), with Celsius being the default unit. It is possible to switch between the two units without requiring a restart of the controller. When the controller temperature exceeds max temperature, the drive stage is disabled and an alert (3010) is shown. The drive stage is once again enabled when the controller temperature drops below the temperature limit.

From the display or through the web GUI, users can access the latest controller temperature measured together with the timestamp when the measurement was taken.
