7.1 Troubleshooting Checkout Failures
Note: If the Automated Checkout (Section 3.2) results in failures, refer to the
following sections to troubleshoot a specific failure. Use EC Service
Application PC based (Section 8.5) while running all tests .
To file a quality report or request technical assistance regarding a checkout
failure, create and include a Checkout log using the EC Service Application.
7.1.1 Paw transducer
check
The Paw Transducer Check can indicate a failure from four conditions:
1. Inspiratory Pressure Sensor Zero Failure:
With the Inspiratory Pressure Zero Valve actuated, raw counts from the
Inspiratory Pressure Sensor must be between 631 and 968; if not, test
results indicate
Fail and the Pinsp sensor out of range message is
displayed.
• Use EC Service Application PC based (Section 8.5) to facilitate problem
isolation.
• Ensure proper connections.
• Remove the Inspiratory Pressure Zero valve. If the Inspiratory Pressure
Sensor values are between 631 and 968 counts, replace the Zero Valve.
• Replace the Inspiratory Pressure Sensor Board.
• Replace the Vent Control board (VCB).
2. Expiratory Pressure Sensor Zero Failure:
With the Expiratory Pressure Zero Valve actuated, raw counts from the
Expiratory Pressure Sensor must be between 631 and 968; if not, test
results indicate
Fail
and Pexp sensor out of range message is displayed.
• Use EC Service Application PC based (Section 8.5) to facilitate problem
isolation.
• Ensure proper connections.
• Remove the Expiratory Pressure Zero valve. If the Inspiratory Pressure
Sensor values are between 631 and 968 counts, replace the Zero Valve.
• Replace the Expiratory Pressure Sensor board.
• Replace the Vent Monitor board (VMB).
3. Cannot achieve 34 cmH
2
O pressure:
The Air (O
2
) flow valve is set to approximately 10 lpm and the test is
initiated if 34 cmH2O pressure is not achieved; test results indicate Fail
but no alarm message is displayed.
• Use EC Service Application PC based (Section 8.5) to facilitate problem
isolation.
• Ensure supply gas is connected.
• Continue with other tests. If a significant leak is indicated during the Low
Pressure Leak test, repair the leak then repeat this check.
• Check respective Flow Control Valve for proper operation.
