7.4.4 Watchdog alarms
There is a watchdog circuit, which monitors for failures of the following components:
• NetDCU (responsible for the graphical user interface WDST#4 error)
• Control PIC (responsible for control of ventilation WDST#16 error)
• Monitor PIC (responsible for monitoring functions WDST#32 error)
• Alarm PIC (responsible for alarm audible indication and lamps WDST#64 error)
In case of a failure, the watchdog opens the pressure relief valves and stops power to the blender
module to prevent and ⁄or relieve pressure in the patient circuit while alarming.

triggered and displayed and the device can be further used.
NOTE
: WDST#8 is not an alarm and only shows that all watchdogs are working correctly.
