Part I — Troubleshooting Overview
Test Setup
The maintenance chapter of this manual provides detailed diagrams and instruction on various setup configurations
which must be strictly adhered too. Failure to follow the correct setup instructions will result in a test failure.
Compressor Preparation
Ventilator design includes components which need to be exercised as part of the maintenance procedure. It is
possible that the device being tested may have been stored for a long period of time. Before connecting the
ventilator to the RCS, exercise the compressor as detailed in both
the occlusion test & stockpile removal procedure,
found within the maintenance chapter of this manual. (Click to Jump)
Connecting the Ventilator
Ensure that the USB connection between the ventilator and the computer is secure. Position the USB cable away
from other components during testing to minimize the possibility of disconnection.
Do not power on the ventilator unless instructed by the prompts in the RCS. Not correctly following the power
prompts during RCS procedures will cause failures during testing.
Ventilator RCS Testing Overview
The RCS employs discrete tests to evaluate a subsystem function and hardware. A process is built by constructing a
sequence of these discrete test as explained below. (RCS prompts, titles, and status messages are noted with bold
italic font throughout this document)
Discrete Tests
Table 1 (RCS Release 5) & Table 2 (RCS Release 8) identify each discrete test and the associated subsystems tested
during the Incoming System Test, Complete Calibration and Outgoing System Test phases of the calibration cycle.
Please refer to Table 1 & Table 2 at the end of this section, along with the Ventilator Troubleshooting Section for
potential solutions to Error Messages.
System Test (Incoming System Test - RCS 7.X)
The System Test phase evaluates the performance of the device relative to its specifications. It evaluates the device
in its current state before applying a new calibration.
Ventilators that have not been operated in the interval since the previous calibration cycle do not need to have the
Incoming System Test run, since nothing has changed in the system performance.
Calibration (Complete Calibration RCS 7.X)
The Complete Calibration cycle evaluates hardware for its ability to be calibrated. This test identifies device
hardware faults, if they exist. Once all calibrations are completed successfully, the calibration table is applied to the
device.
NOTE:
Failures can be expected during the Incoming System Test; the report is used to direct the service program. When
the identified problem has been fixed, use the discrete test to confirm that the fault has been corrected.
