Maintenance Tests

X Series Overview

This chapter includes step-by-step procedures for the following types of maintenance tests:

•

•

•

•

Calibration and Calibration Checks

NIBP Valve, Pump, and Tubing Integrity Tests

Operational Tests

Functional Verification Tests

At a minimum, a trained biomedical technician must perform a CO2 calibration and an NIBP

calibration check once per year. A CO2 calibration check may be performed at any time to

verify the CO2 calibration. It is necessary to perform Functional Verification Tests after a

module is repaired to ensure that the functions of the X Series unit work properly. Use the

checklist at the back of this document (ZOLL X Series Maintenance Tests Checklist) to record

your results of the maintenance tests.

Because the X 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

procedure can be completed in a few minutes and requires no additional test equipment. (See

the ZOLL X Series Operator’s Guide for the Operator’s Shift Checklist.) It is highly

recommended that the Operational Tests be performed at regular intervals to augment the

automatic testing the X Series unit does to ensure readiness.

Functional Description

Overview

This chapter contains functional descriptions of the components contained in the X Series and

the X Series options.

Circuit Distribution

The Defib/Monitor X Series unit consists of two key PCB assemblies, the Monitor Board and

the Defibrillator Board as well as a few modules and assemblies: the Front Panel Keypad

assembly, Status LCD Board, Dock Connector Board, Display, and Printer. The NIBP, CO2,

and SpO2 circuitry reside on modules that connect to the Monitor Board.

Monitor Board

The Monitor board integrates the analog circuitry and interface circuitry for patient parameters,

a digital processing section as well as user interface controls, printer control, audio control, and

power circuitry for the entire system and charging circuitry for the battery. The X Series system

relies on a centralized dual processor engine for its computing needs. The Main Processor (MP)

serves as the primary user interface engine and provides connectivity needs, while the Patient

Processor (PP) controls the patient monitoring and defibrillation-pacing functions. An

additional power controller micro-controller (PC) controls the power sequencing, and battery/

charger interface.

9650-001356-01 Rev. A

ZOLL X Series Service Manual

Page 46

CHAPTER 2 FUNCTIONAL DESCRIPTION

Main Processor (MP)

The Main Processor (MP) section controls the user interface, connectivity needs, as well as data

logging, printing, and general system control. It consists of the CPU, program memory Flash

and SDRAM, Communication with modules/circuits: USB Client, USB Host, Debug Ports

(JTAG,Serial), Storage memory for 24 hour disclosure data, Internal VGA display and interface

circuit, LED indicators, Key Pad, and Audio circuit. The MP also controls the real-time clock

and interface to the power controller processor, battery and charger.

Patient Processor (PP)

The Patient Processor (PP) circuitry supports the data acquisition, signal processing and

conditioning, analysis and control algorithms required for the physiological sensors. The PP

also controls the defibrillation and pacing circuitry. It consists of the processor, program

memory Flash and SDRAM as well as interface circuitry to physiological sensor modules/

circuits.

Power Controller (PC)

The Power Controller (PC) micro-controller controls the power sequencing to turn the device

on and off when the power switch is pressed. It also communicates to the battery charger and

battery via a serial SPI bus. Additionally, the PC controls the Status LCD and communicates

battery and charger status to the MP.

Peripherals Interface

The Communications Processor (CP) is connected to various peripherals:

• MP

• Host Power Control

• USB

• Wifi

• Bluetooth

• GPS

• Expansion FLASH Storage

MP - The CP is connected to the MP via several communication links. The primary link is a

high-speed UART with several GPIO lines for general signaling. Additional provision has been

made for connection with an SPI link that would operate in parallel to the UART. The CP can

perform message-based communication with peripherals that are connected to the MP, such as

the PP, the real-time clock and power controller through the MP.

Host Power Control - The CP uses the Host systems' power controller - HC08 - for system

power state information. This link consists of several GPIO lines. This link provides

information about the connected power sources, imminent shutdown and handshaking.

USB - The USB interface on the CP provides a means to connect USB memory sticks and USB

Cellular Modems.

Wifi - The Wifi interface on the CP is provided over an SDIO interface with auxiliary GPIO

lines for control. This provides the capability for communication with a/b/g/n 802.11 devices.

Collectively, this interface allows the CP to control power, scan for available networks and to

select/deselect a desired connection.

42

9650-001356-01 Rev. A

Page 47

Overview

Bluetooth - The Bluetooth interface on the CP is provided by a UART interface with auxiliary

GPIO lines for control. Collectively, this interface allows the CP to control power, scan for

available devices and to select/deselect a desired connection.

GPS - The GPS interface on the CP is provided by a UART interface with auxiliary GPIO lines

provided for control. Collectively, this interface allows the CP to control power and to listen for

satellites. The UART interface is jumpered and also routed to the expansion connector to

provide a means for accessing the CP's console debug port. If the console port is enabled, the

GPS interface will not be available and vice-versa.

Expansion FLASH Storage - This consists of a block of supplemental FLASH that is

physically separate from the NAND FLASH used to store the boot loaders, kernel and system

software. This partition is used to store upgrade images, patient data and device log data. This

storage exists on the carrier board and is connected to the CP via an SD interface.

ECG 3/5 or 12 Lead Circuitry

X Series supports 3/5 lead and 12 lead ECG acquisition. Analog circuitry provides signal

conditioned data through an A/D converter to the PP. All of the signal processing, lead

derivation, fault detection is performed by the PP. The ECG circuitry utilizes a CPLD for

control of analog circuitry and transmission of data to the PP across an isolation barrier. A

common connector is used to receive 3/5 Lead ECG cables with a 12 Lead ECG extension. The

ECG acquisition inputs are CF defib-proof applied parts. The defib protection resistors reside in

the patient cable. The ECG signals from the external connector on the left side panel are

connected to the monitor board through a flex cable to J28.

Impedance Respiration

X Series provides the circuitry for impedance respiration measurements in 3/5 and 12 lead

configurations. This circuitry provides a low-current 72kHz AC signal across leads I and II of

the ECG cable. The signal is passed through a synchronous demodulator and decoded by the PP

through the ECG CPLD.

Blood Pressure NIBP

The X Series NIBP circuitry resided on module that connects to the Monitor board through J32.

The PP communicates to the NIBP module via a bi-directional, serial bus. The NIBP module

supports both dual lumen and single lumen cuffs. The NIBP pump and valve hoses are

connected to the cuff connector on the left side panel and to the filter on the rear enclosure. The

pump and valve are connected to the NIBP module by short, 2-wire cables.

Invasive Blood Pressure (IBP)

X Series supports up to 3 IBP measurement channels. The IBP circuitry supports AAMI BP-22

transducers (5uV/V/mmHg). The PP communicates directly to the IBP ADC over an isolated

serial bus through the FPGA. The IBP probes connect to the monitor board through the IBP/

Temp wire harness which connects to J33 of the Monitor board.

SPO2 Module

X Series supports the Masimo Module that mounts to the Monitor board and communicates

through J36 and J40. The SpO2 module communicates across an isolation barrier using a

CHAPTER 2 FUNCTIONAL DESCRIPTION

End tidal CO2 (CO2)

X Series supports an Oridion® Microstream® CO2 module. The CO2 module mounts to the

Monitor board and communicates to the board through a cable connected to J50. Serial

communications from the monitor board is implemented via a UART on the PP. The CO2

module obtains gas samples from the sampling lines through tubing and a 3-wire cable

connected to the left side panel.

Thermometry

X Series supports two simultaneous temperature measurements. YSI400/YSI700 series probes

are used to make temperature measurements. Data is communicated to the PP from the

Temperature ADC via and isolated SPI bus through the FPGA. The Temperature probes

connect to the monitor board through the IBP/Temp wire harness which connects to J33 of the

Monitor board.

Power Circuitry, Battery Charger, DC-DC converters

Power circuitry for all subsystems but the defibrillator-pacer module reside on the Monitor

Board. Auxiliary Power and Battery Power are automatically switched to provide constant

current, the unit draws current from auxiliary power when present. There is a smart battery

charging circuit that will charge the battery when Auxiliary power is present. Switching mode

DC-DC converters are utilized to make internal 6V, 5V, 3.3V, 1.8V and processor core voltages.

Regulators are used to provide regulated supply voltages with low dropout for low current

consumption circuits. Each of the isolated modules, Temp/IBP, ECG, SpO2 have independent

power supplies. Isolated power supplies are designed for isolating Patient Applied Parts. The

MP via the FPGA GPIO has the ability to shut down voltage rails or power to individual patient

parameters. Power from the battery connects to the Monitor board through J29. Auxiliary

power connects to the Monitor board through J31.

USB Host Port

X Series Monitor Board incorporates one USB Host ver 1.1 port. The port uses the USB

controller built into the PXA270 Main processor. Full speed of 12 Mbps and Low speed

1.5Mbps are supported. The Host port supports a USB flash memory stick for data export. The

USB host connector is in the right side panel and connects to the Monitor board through J44.

Defibrillator Pacer Module

The Defibrillator/Pacer Module consists of two PCB assemblies connected by a flex cable. This

Defibrillator/Pacer module relies on proven core defibrillation/pacing technology for improved

power conversion efficiency, reduced EMI, and improved stability in volume production. This

module contains power supplies, charging and discharge circuitry, pacing circuitry, and the

Pads/Paddles ECG preamplifier and impedance circuitry. Communication with the

Defibrillator/Pacer module is a function of the PP. The ECG-Charger board contains the

charger circuit, ECG acquisition circuitry, and protection components. The

Processor-Bridge-Pacer board contains the micro controller, CPLD, Pacer, and defibrillation

shock delivery circuit.

Overview

Defib CPLD

The Defib CPLD provides I/O control for the Pacer circuitry, the defibrillator charging and fire

control circuitry.

Pace/Defib (PD) Micro controller

The PD micro controller communicates with the PP processor on the monitor board to accept

commands to control the defibrillator and pacer. The PD micro controller controls the pacer

current and pulse timing and the defibrillation charging and waveform generation.

Communication between the Monitor and Defibrillator/Pacer boards is routed through the flex

cable connected to J106 of the defibrillator board and J38 on the Monitor board.

Charging Circuit

This is a high voltage step-up inverter that charges the Defib Capacitor. It provides electrical

isolation between the defib output and the system. The charging circuit will charge the Defib

Capacitor to up to 2775V. The Defib Capacitor is connected to the Defibrillator/Pacer board

through the 2-wire cable connected to J119.

Fire and Relay Circuit

The fire circuit employs high voltage switching devices to deliver a biphasic waveform to the

patient. Switching devices are utilized to produce a Rectilinear Biphasic® waveform. In

addition, relays are located between the fire circuit and the patient for electrical isolation. They

are engaged only when a valid command is set from the Defib CPLD.

Pacer

Pacer circuit delivers pacing pulses under control of the PD micro controller over an isolation

transformer. The pacer circuitry consists of an adjustable constant current power supply, pulse

timing, and current monitoring circuits.

Pads/Paddles ECG Preamplifier

This is a single channel ECG preamplifier paddle pick up that monitors the patient ECG signal

from the Defib paddles (or pads). It digitizes this signal and delivers it to the PP processor via

the PP interface. This preamp is a simplified version of the 3/5/12 Lead ECG utilized on the

Monitor Board.

Paddle Interface

Paddle interface circuitry detects analog voltage levels to decode switches and ID resistors of

the standard ZOLL paddles and internal paddles. The paddle set interface is connected to J115

of the Processor-Bridge-Pace PCB.

Printer

X Series uses an internal thermal printer of 80 mm paper size that is built into the Defib section

of the enclosure. Communications with the printer is bi-directional, serial, (Main CPU to/from

printer) and complies with the software/hardware interface of the internal printer.

Communications are implemented using hardware Universal Asynchronous Receiver.

Transmitter (UART). The printer is controlled by the MP and is connected through a cable to

J46 and J49 of the Monitor board.

CHAPTER 2 FUNCTIONAL DESCRIPTION

Lithium Ion Battery

The portable X Series device is powered by a removable Lithium Ion battery pack. This battery

pack incorporates protection circuitry and "smart battery" circuitry. The battery power is routed

from the 2-pin connector on the rear of the device to J29 of the Monitor board. The Power

Controller communicates to the smart circuitry on the battery through the 4 spring contacts

connected to J34 on the Monitor board.
