7.5 Troubleshooting System Malfunction (safe-state) screen

Machine logs
7-6
• Compatibility incomplete: No versions received from Vent SIB
• System Self-tests failed
The above error log entries are due to the Ventilator failing its Power-On Self Test (Post).
When the ventilator fails its self-test, the system enters the safe-state.
The likely cause is a Gas Inlet Valve Solenoid that is not transitioning to the
de-energized state when valve drive power is removed.
Troubleshooting above stated condition:
• Replace the Gas Inlet Valve Solenoid (Section 9.13.2).
• If problem continues, replace the Gas Inlet Valve components (Section 9.13.3).
