Safety Welch Allyn Connex® Vital Signs Monitor 6000 Series™

General safety considerations

• If the monitor detects an unrecoverable problem, it displays an error message. For more information see “Troubleshooting.”

• To ensure patient safety, use only accessories recommended or supplied by Welch Allyn. (See the accessories list in the device’s directions for use). Always use accessories according to your facility’s standards and according to the manufacturer’s recommendations and instructions. Always follow the manufacturer’s directions for use.

• Welch Allyn recommends that only Welch Allyn service personnel or an authorized repair center perform warranty service. Performing unauthorized service on a device that is within warranty may void the warranty.

Electrostatic discharge (ESD)

Caution Electrostatic discharge (ESD) can damage or destroy electronic components. Handle static-sensitive components only at static-safe workstation.

Caution Assume that all electrical and electronic components of the monitor are static-sensitive.

Electrostatic discharge is a sudden current flowing from a charged object to another object or to ground. Electrostatic charges can accumulate on common items such as foam drinking cups, cellophane tape, synthetic clothing, untreated foam packaging material, and untreated plastic bags and work folders, to name only a few.

Electronic components and assemblies, if not properly protected against ESD, can be permanently damaged or destroyed when near or in contact with electrostatically charged objects. When you handle components or assemblies that are not in protective bags and you are not sure whether they are static-sensitive, assume that they are static-sensitive and handle them accordingly.

• Perform all service procedures in a static-protected environment. Always use techniques and equipment designed to protect personnel and equipment from electrostatic discharge.

• Remove static-sensitive components and assemblies from their static-shielding bags only at static-safe workstations—a properly grounded table and grounded floor mat—and only when you are wearing a grounded wrist strap (with a resistor of at least 1 megohm in series) or other grounding device.

• Use only grounded tools when inserting, adjusting, or removing static-sensitive components and assemblies.

• Remove or insert static-sensitive components and assemblies only with monitor power turned off.

• Insert and seal static-sensitive components and assemblies into their original static-shielding bags before removing them from static-protected areas.

• Always test your ground strap, bench mat, conductive work surface, and ground cord before removing components and assemblies from their protective bags and before beginning any disassembly or assembly procedures.

Battery performance

About the battery

The device uses a rechargeable lithium ion smart battery. Internal circuitry enables the battery to report its condition to the device. The device displays the battery status via the LED power indicator, icons on the screen, and status messages appearing in the Device Status area of the display. Battery information may be collected using the service tool.

New batteries are shipped from the manufacturer with a 30 percent charge to extend shelf life. When installing a new battery in the device, you must plug the device into AC power to wake up the battery. If the AC power is not applied to the device, the new battery will appear discharged.

The Device Status area displays a low-battery status message when 30 minutes of power remain and again when 5 minutes remain.

You can expect new, fully charged batteries to have enough power for the following:

• Six-cell batteries provide approximately 26 patient exams.

• Nine-cell batteries provide approximately 47 patient exams.

Note A patient exam includes NIBP, temperature, and SpO2 measurements at the rate of

The number of exams per charge decrease with the battery age.

Depending on the age of the battery, a 6-cell battery takes 3 hours and a 9-cell battery takes 4 hours to fully charge at room temperature.

Both batteries have a lifetime of 300 charge cycles or more, where a charge cycle is equal to fully charged to discharged to fully charged at room temperature.

Battery charging is provided by the device’s internal power supply.

For a complete list of battery specifications, see the device’s directions for use.

Best practices

The following practices help to extend the life of the battery and the device.

• Remove the battery when storing the device.

• Replace batteries that trigger a low battery status message when fully charged.

Power-up sequence

The system performs a power-on self test (POST) each time the device is powered on. During power up, the system performs a comprehensive self test of the software. If software testing is successful, the system then tests internal hardware. If all tests are successful, the system completes power up and the Home screen appears.

To perform the POST:

1. Disconnect any patient cables connected to the system.

2. Insert a fully charged battery into the system.

3. Upon each power up, confirm the following:

a. The light bar flashes red then amber.

b. The Welch Allyn startup screen appears.

c. A beep sounds, followed by two chimes.

Note If no chimes sound, replace the speaker as specified in

“Remove the speaker.”

d. The product line logo appears at the bottom of the screen.

e. If a printer is installed, the paper advances slightly.

f. The Home screen appears.

WARNING Equipment failure risk. The system includes a fan that circulates air through the device. If the fan does not run when you power up the device, remove it from use and inform qualified service personnel immediately. Do not use the system until the problem is corrected.

If the internal self-check is successful, the system shows its normal functions with all values blank and the system is ready for operation. If the self-check fails, an error message appears in the system status area at the top of the screen. If a fault that could adversely affect the product is detected, the system enters a safe mode and stops monitoring patients. The system remains in safe mode until it is turned off by pressing the Power button or until it shuts down automatically after a period of inactivity.

If a system error is detected, the system becomes inactive until you press or until the system

shuts down automatically. The system displays a system fault message that contains a wrench icon( ) and a system fault code to aid service and engineers in diagnosing the problem.

While in safe mode, the red LED bar and the piezo buzzer cycle on and off.

Troubleshooting

This section provides the following tables to help troubleshoot the device.

• Symptoms and solutions: These tables list symptoms you might observe, list possible causes, and suggest actions that may eliminate the problem.

• Technical alarm messages: These tables list messages generated by the device software when a problem is detected. The tables explain possible causes and suggest actions that can resolve the problem.

These tables can help you diagnose and fix a problem. They do not replace basic troubleshooting skills. You must still trace the source of the problem to the board or module level to decide the best course of action. Welch Allyn does not support component-level repair to the board or module. For available replacement parts, see “Field Replaceable Units.”

WARNING Do not perform troubleshooting on a device that is emitting smoke or exhibits other signs of excessive overheating. Disconnect the device from AC power and call Welch Allyn Technical Support immediately.

Caution Replace parts, components, or accessories only with parts supplied or approved by Welch Allyn. The use of any other parts can lead to inferior device performance and will void the product warranty.

NIBP accuracy check

The NIBP accuracy check is performed manually using the service tool to close the valves. The accuracy check compares the reading from the primary transducer pressure shown in the service tool window with the reading from an external calibrated digital pressure meter. The results of this check are not recorded in the service tool log file. To record the results for your records, copy the table in the service manual. If a calibration verification is required, run the NIBP calibration included with the Gold edition of the service tool.

Caution False equipment error can occur. This accuracy check verifies only the accuracy of the primary transducer. If the safety transducer is out of calibration, a false error can occur due to the pressure difference between the primary and safety transducer. To prevent potentially false errors, Welch Allyn recommends a qualified service technician perform a full functional verification and calibration on an annual basis.

Set up the 9600 Plus calibration tester

Place the tester on a level surface away from sunlight, drafts, and other sources of heat or cold.

The tester takes approximately 20 minutes to heat to the lowest set point.

To expedite testing, Welch Allyn recommends the following practices:

• To eliminate waiting for the tester to heat to the next set point, use three testers, each set to one of three different set points.

• When using only one tester to test several thermometers at all three temperatures, test all thermometers at one set point before proceeding to the next set point.

• To eliminate waiting for the tester to cool down, start at the lowest set point. Because the tester does not have an internal fan, it requires more time to cool down than to heat up.

Change the 9600 Plus set point

To scroll from one set point to the next, press and hold the Temperature Selection button until a beep sounds.

The new set point appears in the upper left corner of the LCD display. The device’s current temperature appears, flashes, and continues flashing until the cavity reaches equilibrium at the new set point. The 9600 Plus beeps when the set point is reached.

Perform a SureTemp temperature probe and system test

1. Set the 9600 Plus to the desire set point and wait for the display to stop flashing.

2. Insert the temperature probe, without a probe cover, into the thermistor device port on the tester.

3. When appears on the display, touch it to switch to Direct mode.

4. Wait for up to two minutes for the temperature reading to stabilize.

5. Record the results in the temperature service record.

6. Return the temperature probe to the probe well on the device.

7. Repeat the procedure as necessary until all thermometers are tested at each temperature.

To record the results of your test, go to “Service record.”

The Gold edition is required to verify that the device is functioning correctly after it has been serviced. Although all of the option upgrades are calibrated and tested before leaving the factory, Welch Allyn recommends performing a complete functional test whenever the device is serviced.

Software upgrades, when available, can be purchased or provided at no charge if your device is covered by a Welch Allyn Service Agreement. The upgrades can be installed by either a Welch Allyn service center or by using the service tool, Silver or Gold edition.

If you choose to install software upgrades on your own, you will receive the software through the internet. When ordering software, provide the serial number of the device you want to install the software on.

Licenses are available for purchase to turn on additional software features or communication options. If you want to install licenses, you will need the service tool, Silver or Gold edition, and an internet connection. If you purchase a license, you will receive a code to enter in the service tool running on a PC connected to the internet that will contact a server and download the license file. The service tool connects with the device to install the license to turn on the advanced feature. A more detailed description of the license process can be found in the service tool help files.

Note When a license authorization code is used to activate the license, the authorization

code is tied to the device’s serial number. Save the license authorization code with the serial number for future use. If the main board is replaced, you will need the authorization code to reactivate the license files.
