With one fully-charged battery in a standard configuration, the monitor operates up to four (4) hours.

The battery icon shows if the batteries are inserted. This icon shows how much charge the batteries have. The icon updates every six seconds and is to the left of the audio icon on the lower-right section of the monitor. Refer to Table 1-5 on page 1-15.

Charge temperature limits are ≤80% RH.

The battery must be capable of continuous charge at 12.6 V. To charge the battery, only use a dedicated level II or level III smart battery charger. When you use a level II or level III smart battery charger, the battery requests the appropriate charging voltage and current.

The FULLY_CHARGED bit in the Battery Status is set when the charging current tapers down to under 240 µA, while charging at

12.6 V.

Notes:

• The battery life greatly depends on usage, age, and the

environment. The battery operating life decreases over time.

The option B monitor operates for up to four hours with two fully charged batteries and standard configuration. With a single fully charged battery and standard configuration, the monitor operates for up to two hours. The battery is not removable from the monitor.

The option C monitor operates for up to two hours with a single fully-charged batteries and standard configuration. The battery is not removable from the monitor.

Note:

For options B and C monitors, only one battery icon shows on the main screen.

Caution:

The qube monitor and smart rechargeable Li-Ion batteries and cells do not overheat, they have internal protection devices. Overexposure to heat will activate one of these devices and may permanently disable the battery. If this happens, contact Spacelabs Healthcare to purchase a replacement battery.

Refer to To change batteries without interruptions while operating

on battery power on page 1-15 for details.

For information on alarms configuration and alarm tones, refer to the XPREZZON™ and qube™ System Administration Manual.

Cables

Maximum Cable Lengths

The list of cables that follow are limited to the indicated maximum length:

• SDLC Cable — 40 feet (12.2 m) maximum (total length from the monitor to the last device on the bus). For longer SDLC cable runs, contact your local customer service representative.

• DVI-D Video Cable — 16 feet without a repeater. For distances greater than 16 feet, a repeater may be required in order to guarantee signal quality.

• Ethernet cable (10/100BaseT) — 328 feet (100 m) maximum.

SDLC External Devices

External devices (for example, Flexport® system interfaces) can be connected to the SDLC bus. In this context, the term external means connected to the SDLC bus by cable through an external connector. This is in contrast to modules, which are connected by inserting them into a module housing.

If multiple module housings are present, external devices must be connected to the last module housing in the daisy-chain (the housing electrically farthest from the monitor on the SDLC bus). Even though multiple connectors can be available, only the SDLC connector on the most distal module housing can be used for connecting external devices. Do not use more than a single Flexport connector, regardless of how many module housings are present (refer to Figure 2-8, Figure 2-9, or Figure 2-10 depending on your monitor option).

If you install multiple Flexport interfaces, they must be daisychained using the T-cable supplied with those devices. Up to three Flexport interfaces can be connected in this way (refer to Figure 2-

8, Figure 2-9, or Figure 2-10 depending on your monitor option).

Non-terminated Terminate

SDLC Cable Interconnection

To ensure Electromagnetic interference (EMI) compliance, the appropriate Spacelabs Healthcare 9-pin connector must be used. Refer to the Module Housing Service Manual (P/N 070-0680-xx).

SDLC Bus Termination

The SDLC bus must be properly terminated for correct operation. If no external devices (for example, Flexports or multigas analyzers) are connected, proper termination of the SDLC bus is accomplished automatically. If external devices are connected, the switch on the module housing farthest from the monitor must be set to the terminated ( ) position. All others must be set to the nonterminated ( ) position. The SDLC clock and data signals are switched by the terminator switches and are not present “downstream” of any switch set to the position.

S ETUP

Because bus termination is handled by setting the switches appropriately, an external terminator is only required when external devices are connected.

If external devices are connected, an external cable terminator is required to terminate the SDLC bus. This must be installed at the end of the SDLC bus (following the last external device). In this case, all module housings must have their switches in the position.

Note:

Flexports require a powered Flexport cable (P/N 012-0555-00) when used with the 90499 module housing. SDLC data is only passed along to the external device or devices when the terminator switch (SW2) is in the position.

Alarm Relay for option A

Alarm output signals are available at the Nurse Alert ( ) connector instantaneously when an alarm occurs. Table 2-3 describes the connector pinouts for remote alarms. Figure 2-12 on page 2-16, Figure 2-13 on page 2-16, and Figure 2-14 on page 2-17 illustrate the circuits for each alarm function.

T HEORY

A PCI bus is used to communicate to the ATI / ES1000 GPU, USB host controller, and optional wireless card (refer to Figure 3-2 on page 3-2).

The USB host controller has 5 USB ports and interfaces to:

• USB port 1 - USB Flash Drive

• USB port 2.3 - becomes external USB1, USB2

• USB port 4 - drives USB Hub on Mon-Dock PCBA

• USB port 5 - drives recorder.

If replacement is ever required, an internal flash drive provides bulk memory and has special formatting requirements.

An on-board FPGA is used for SDLC Clock generation, and audio clocks 11.3541 MHz (+/-1%). It is also used for SPI to I2S serial bus conversion to interface the MPC8270 to the audio codec. The FPGA is also responsible for decoding the IR remote control signals when used with the 90360-01 remote control.

Figure 3-4 Power Supply Subsystem

The Power Supply and Battery Charger subsystem (refer to

Figure 3-4) consists of several subsystems:

• Always On (AO) MCU that provides ON/OFF control

• Battery management / charging control

• Voltage monitoring

• PWM for backlight

• Power sequencing

• Unit shutdown warning (PFAIL)

• Internal temperature monitoring

• Control of +12V, +5V, +3.3V, -12V power supplies

To show and monitor the supply voltages, open the Biomed menu, click the System Info tab, then select the Analog key. If out of range conditions are presented, voltages are checked at power-on, and during run time and events are logged.

T HEORY

The LTC1960 battery charger IC interfaces with the AO MCU. It is responsible for load switching between AC and battery or batteries, and direct communication via SMBUS protocol to the Li-Ion smart batteries. The IC is also responsible for charging the batteries. Refer to the battery section for more information on batteries.

For 670-1573-03 CPU PCBAs and higher, a high priority technical alarm has been added. The AO MCU triggers a technical alarm in the following events:

• Out of tolerance voltages on the +3.3V, +5V, +12V, and -12V supplies

• No host CPU MPC8270 response

• If the AO MCU also fails to update the watchdog circuit

The technical alarm is a redundant alarming circuit that does not use the main CPU audio. This circuit can derive power from the external power supply, battery, or supercap incorporated in the circuit. The safety circuit sounds if: the unit is unplugged from AC and no battery is present, or if the unit is operating on battery and the battery is depleted.

Li-Ion Batteries

If either the charger or host device fails to function correctly, electronic circuitry is permanently connected within the battery pack to prevent damage. If an illegal current source is placed across the battery terminals or an illegal load is connected, the circuitry also protects the battery. Redundant levels of protection have been implemented (the primary protection levels are auto-resettable and the secondary are non-resettable).

If any cell voltage >=4300 µV, the primary protection circuit prevents the battery from charging. It allows charging again once all cell voltages are <=4150 µV. If any cell voltage >=4.45 V +/-0.05 V by blowing a power path logic fuse, the secondary protection circuit prevents the battery from charging. The fuse is non-resettable, which renders the battery pack nonfunctional.

The primary protection circuit also provides over-temperature protection and prevents the battery from charging at temperatures =>54º C. Then, once the battery temperature has cooled to <=45º C, it again allows charging.

The primary protection circuit also provides continuous over-current protection and prevents the battery from charging at Current() =>4.25 A. Then, once the Average Current() <= 200 µA for 70 sec, the battery will retest the overcurrent condition, and again allow charging.

www.spacelabshealthcare.com

The primary protection circuit prevents the battery from being further discharged once any cell voltage reaches <=2500 µV. Then, once all cell voltages are >= 3000 µV, it allows discharge again.

3-5

91390

QUBE

T HEORY

The primary protection circuit also provides over-temperature protection and prevents the battery from discharging at temperatures =>75º C. Then, once the battery temperature has cooled to <=65º C, it allows discharging again. If the battery reaches 85º C for any reason, the secondary protection circuit blows the in-line power path logic fuse. The fuse is non-resettable, which renders the battery pack nonfunctional.

The primary protection circuit also provides continuous over-current protection and prevents the battery from discharging at Current() <= -6.25 A. Then, Once the Average Current() >= -200 µA for 70 sec, the battery will retest the overcurrent condition, and again allow discharging.

If a short-circuit is placed across the battery + / - terminals, the primary protection circuit prohibits the discharge of the battery. When the Average Current >= -1 µA for 70 sec, the battery retests the short-circuit condition, and again allows discharging. The pack is designed to withstand reasonable in-rush currents without resetting the electronics and without interrupting the discharge cycle.

A thermal fuse is fitted in series with the charge/discharge path to protect the battery from over temperature. This device goes open circuit if the cell case temperature reaches the fuse's temperature rating of 93° C (+0° C, -5° C). The fuse cannot be reset, which renders the battery pack nonfunctional.

A current slow-blow fuse is assembled in series with the battery pack to protect the battery pack against abusive overcurrent overload. The hold current is rated at 12 A for 4 hours (minimum @ 25C). The fuse is non-resettable, which renders the battery pack nonfunctional.

Warning:

Make sure that a functional Li-Ion battery SLHC P/N 146-0142-xx is installed in the unit as part of safety checks. Gas, BISx, and SvO2 modules do not have battery backup of alarm settings, and alarm settings reset to defaults if monitor power is interrupted for more than three minutes.

The monitor docking PCB has a docking connector for interface to a docking station (refer to Figure 3-9). All I/O connectors and power are routed on this board. They are available to either the docking station when docked, or presented at the rear of the monitor when not docked. High-speed signals like Ethernet, DVI and USB are switched so the unused stubs when docked do not affect the signal impedance.

• All screws are tight.

• The case and connector pins are not damaged.

• There are no frayed or pinched wires or cables.

Tests for Electrical Safety

To protect the patient from electrical shock, especially micro-shock, do the required safety tests. It has been determined experimentally that current values in the microampere (mA) range can cause fatal arrhythmias in electrically susceptible patients. A patient is deemed electrically susceptible when connected to monitoring equipment.

Definitions

Classification — IEC/EN/UL 60601-1 Safety standard designation for the class of equipment and type of patient applied parts that indicate the degree of protection provided against electrical shock.

Leakage Current — Current that is not functional. It includes patient leakage, ground leakage, and enclosure (or chassis) leakage.

Patient Lead Leakage — Current that flows from the applied part of the patient lead to ground.

4-2

Chassis Leakage — Current flowing from the enclosure (or from conductive parts accessible to the operator) through the ground conductor.

www.spacelabshealthcare.com

Normal Condition — Condition in which all means provided for protection are intact. Includes, ground connections, insulation, creepage, and clearance distances.

Single Fault Condition — Open ground, open neutral, line voltage on a patient connection, or any single state other than normal condition that could compromise patient safety.

UUT — Unit Under Test.

Spacelabs Healthcare does not endorse standards to the exclusion of others. Therefore: BE SURE TO CHECK YOUR LOCAL

REQUIREMENTS TO MAKE SURE YOUR EQUIPMENT SAFETY TESTS COMPLY WITH LOCAL STANDARDS. Generally accepted

standards for medical monitoring equipment, such as the Underwriters Laboratory (UL) and the National Fire Protection Association (NFPA) standards, are summarized in Table 4-1 on page 4-3.

The Boot menu and the power-ON diagnostics are described in the sections that follow.

Power-ON Diagnostics

Power-ON diagnostic tests make sure of system hardware integrity during power-on and can often help isolate and troubleshoot a problem. Most of these tests can also be done in the extended diagnostic mode.

TROUBLESHOOTING

The diagnostics done at power-ON include:

• CPU—reads and writes control registers and does an internal wraparound of one serial communication controller channel.

• DRAM read/write—reads and writes DRAM above 1 MB.

• Real-time clock—makes sure that the clock is running.

• GDS SRAM—reads and writes all of the SRAM, nondestructively.

• Video—tests the video memory, video controller, H-sync, and blue video signals.

Boot Menu

TROUBLESHOOTING

The Boot menu can only be accessed during a system startup (cold boot). It allows access to several basic configuration menus and functions of the monitor, including Extended Diagnostics. If the serial port is configured for DIAGNOSTICS in the Biomed Menu, all text shown on the screen is also output to the serial port.

To access the Boot menu if the display is functional

1 Power ON the monitor and wait for the 4, 3, 2, 1 countdown

(Refer to Figure 5-1 on page 5-2).

2 Before the countdown expires, do the following step based on

what equipment you use that is connected to the serial port:

• Touchscreen — Touch the bottom left and then the bottom right corner (not simultaneously) of the screen (Figure 5-2 on page 5-4).

• Mouse — Click the left and right mouse buttons simultaneously.

• Terminal or Keyboard — Press CTRL+D.

Extended Diagnostics

TROUBLESHOOTING

(v3.03.00 and higher)

Extended diagnostic tests, like the power-ON diagnostics, can be used to troubleshoot and isolate many system failures. The types of tests and features available in the extended diagnostics are:

• Power-ON diagnostics.

• Interactive tests and read/write memory tests that are not appropriate during power-ON diagnostics.

•Touchscreen calibration and data dump utilities.

• System data dump and system reset utilities.

The diagnostic menus allow most of these tests to be run individually or all at once. If Loop mode is activated, a test can be executed in a continuous loop. If Halt On Error mode is activated, the looping stops when a diagnostic failure is detected. To avoid false failures, do not use the touchscreen, mouse, or keyboard while the diagnostic tests execute.

Any error that occurs during one of these tests is logged in the nonvolatile memory (NVRAM). Refer to Error Log on page 5-11 to retrieve the log.

For detailed information on extended diagnostics and how to run them, Refer to Diagnostic Menus on page 5-8.
