Ventilator & Calibration Troubleshooting
906-0731-04-01 Rev. C ZOLL Ventilator Service Manual 6–3
Hardware faults indicate maintenance is required to apply a calibration.
System Tests (Outgoing System Tests RCS 7.X)
The Outgoing System Test ensures the device hardware meets all functional and performance specifications. After
troubleshooting or repair, the outgoing system test will confirm that the ventilator is operating within expected
tolerances.
The calibration tables for the device are tested and performance specifications are confirmed. The number of re-
tries is limited to three. If the issue persists, record the fault and contact technical support.
Device Alarms
Each alarm is assigned a service code which reflects its priority. All alarms are grouped into general categories
(Patient Safety, Environment and Use, Self-Check) to help resolve the alarm condition. For additional information on
device alarms and service codes, see section III of this chapter. (Click to jump).
Determining which components or sub systems require attention is accomplished by reviewing service codes,
incoming system test results and maintenance records for the device.
Device alarms which indicate a hardware problem are identified in the subsection of this chapter “Ventilator
Troubleshooting” (Click to jump).
Observations
Observations are identified in the troubleshooting section which are derived from review of tool users in both
manufacturing and service. Resolutions are provided to direct the technical actions taken by all technicians.
Service Kits and Replacement Parts
The service kits and replacement parts are listed in Chapter 4 of this Service Manual. Please refer to Chapter 4 for
Part Number and ordering information.
NOTE:
The use of RCS with the device may generate alarm conditions that are expected as part of the testing procedure.
Typically, this is to ensure proper function of the alarms.
High Priority Communication Alarms may occur at various points in the testing and may require a power cycle to
clear the alarm condition.
The alarm history menu, available on devices configured with Release 5, indicates alarms that have occurred during
operation, including use with RCS. The review of this file may indicate hardware faults or failures that occurred in
recent service operations.
