E Series Service Manual

Preface

ZOLL® Medical Corporation’s E Series® Service Manual is intended for the service technician whose responsibility is to identify malfunctions and/or make repairs at the subassembly level. The ZOLL E Series Service Manual has five main sections and one appendix.

Preface—Contains safety warnings and an overview of the manual’s contents. Be sure to review this section thoroughly before attempting to use or service the E Series unit.

Chapter 1—Maintenance Tests explains how to check the defibrillator’s performance using a series of recommended checkout procedures to be conducted every six months.

Chapter 2—Troubleshooting provides a listing of the procedures and error messages to help the service technician detect faults and repair them. Chapter 3—Replacement Parts List displays a complete list of ZOLL part numbers for field replaceable parts available for the E Series unit, allowing

the service person to identify and order replacement parts from ZOLL.

Chapter 4—Functional Description provides technical descriptions for the E Series major subassembly modules. Appendix A—E Series interconnect diagrams and maintenance checklists.

Safety Considerations

The following section describes general warnings and safety considerations for operators and patients. Service technicians should review the safety considerations prior to servicing any equipment and read the manual carefully before attempting to disassemble the unit. Only qualified personnel should service the E Series unit.

Federal (U.S.A.) law restricts this unit for use by or on the order of a physician. Safety and effectiveness data submitted by ZOLL Medical Corporation to the Food and Drug Administration (FDA) under section 510(K) of the Medical

Device Act to obtain approval to market is based upon the use of ZOLL accessories such as disposable electrodes, patient cables and batteries. The use of external pacing/defibrillation electrodes and adapter units from sources other than ZOLL is not recommended. ZOLL makes no representations or warranties regarding the performa nce or ef fectivenes s of its product s when used in conjunction with pacing/d efibrillation elect rodes and adapter units fro m other sources. If unit failure is attributable to pacing/defibrillation electrodes or adapter units not manufactured by ZOLL, this may void ZOLL's warranty.

Only qualified personnel should disassemble the E Serie s unit.

WARNING! This unit can generate up to 2250 volts with sufficient current to cause lethal shocks.

9650-1450-01 Rev. A v

E Series Service Manual

All persons near the equipment must be warned to STAND CLEAR prior to discharging the defibrillator. Do not discharge the unit’s internal energy more than three times in one minute or damage to the unit may result. Do not discharge a battery pack except in a ZOLL SurePower™

Charger Station or compatible ZOLL Battery Charging/Testing unit.

Do not use the E Series in the presence of flammable agents (such as gasoline), oxygen-rich atmospheres, or flammable anesthetic s. Using the un it near the site of a gasoline spill may cause an explosion.

Do not use the unit near or within puddles of water. Note: The E Series is protected against interference from radio frequency emissions typical of two-way radios and cellular phones (digital and analog)

used in emergency service/public safety activities. Users of the E Series should assess the unit’s performance in their typical environment of use for the possibility of radio frequency interference from high-power sources. Radio Frequency Interference (RFI) may be observed as shifts in monitor baseline, trace compression, or transient spikes on the display.

Additional Reference Material

In addition to this guide, there are several other components to the ZOLL E Series documentation. They include:

Maintenance Tests

Overview

The E Series has two checkout procedures: the operator’s shift checklist and the extensive six-month maintenance tests checkout procedures. Because the E Series units must be maintained ready for immediate use, it is important for users to conduct the Operator’s Shift Checklist procedure at the

beginning of every shift. This proce dure c an be c omplet ed in a few mi nutes an d re quires no additional test equipment. (See the ZOLL E Guide for the Operator’s Shift Checklist.)

A qualified biomedical technician must perform a more thorough maintenance test checkout every six months to ensure that the functions of the E Series unit work properly. This chapter describes the step by step procedures for performing the six back of this document (ZOLL E

Series Maintenance Tests Checklist) to record your results of the maintenance tests.
