# Health

On the home view, go to the Controller tab, select Hardware on the left pane and go to the Health window to find information about the Battery status and the temperature of the various components.

## Battery status

The POWER FOCUS 8 battery is located inside the controller's front panel and serves as backup power for some system elements, such as the internal clock. The status of the battery is updated once a day and when the controller restarts. When the battery is close to being completely depleted, a warning (3011) will be displayed. Replace the battery as soon as possible when the warning appears.

The status of the battery appears in the Battery status field on the Health window.

## Controller components temperature

The temperature of the various components in the controller is monitored continuously by the POWER FOCUS 8. Supported temperature units are degrees Celsius (°C) and degrees Fahrenheit (°F), with Celsius as the default unit. It is possible to switch between the two units without requiring a restart of the controller. When a critical component temperature exceeds the maximum temperature, the drive stage is disabled and an alert (3010) is shown. The drive stage is once again enabled when the component temperature drops below the maximum temperature limit.

For each component, the latest controller temperature measured together with the timestamp when the measurement was taken appears in the Controller temperature field on the Health window. It is possible to monitor the temperature continuously in a graph view for a component.
