When the ventilator detects one of the following hardware faults, the HW FAULT alarm is generated:
• The cooling fan is not operating, or the fan filter may be blocking the fan (see page 13-2 for
cleaning and installation instructions).
• A problem is detected with the analog to digital converters.
• A problem is detected with the flow valve.
• A problem is detected with the processor.
• A problem is detected with the EEPROM memory.
• A problem is detected writing data to the EEPROM during system shutdown.
• A problem is detected with the audible alarm circuitry.
• A problem is detected with the alarm sounder.
The HW FAULT alarm may occur as a result of ESD

temporary, the alarm will automatically silence when the condition clears. If the problem persists, or
you experience repeated HW FAULT alarms, immediately contact a certified Pulmonetic Systems’
service technician or Pulmonetic Systems.
• To determine the type of hardware fault detected by the ventilator, see Appendix E - Event
