Propaq 100-Series Monitors Safety Summary

Safety

Summary

CAUTION

WARNING

The general safety information in this summary is for both operating and
servicing personnel. Specific warnings and cautions will be found
throughout the Operator’s Guide and other manuals where they apply. Such
specific warnings and cautions may not appear here in this summary.

CAUTION statements in the documentation identify conditions or practices
that could result in damage to the equipment or other property.

WARNING statements in the documentation identify conditions or practices
that could result in personal injury.

Symbols The following symbols may appear in the documentation, and on labels on

the Propaq monitors.

DANGER: Risk of explosion when used in the presence of flammable
anesthetics. (This is on older versions only.)

Type CF, Isolated patient connections comply with the allowable risk
(leakage) current limits for direct cardiac application and are protected
against the effects of defibrillation.

Type BF, Isolated accessible and applied parts comply with the allowable
risk (leakage) current limits for noncardiac body applications, protecting the
patient and operator from risk of electric shock.

Protected against water dripping vertically. (Protection Classification IPX1
per IEC Publication 529.)

IPX1

DC power input connector for applications not requiring a “high output”
power adapter.

DC power input connector for applications requiring a “high output” power
adapter.

For continued fire protection, use only the specified fuse.

Internal power transformer meets requirements of a short-circuit-proof
safety-isolating power transformer (symbol is located on ac power adapter).

Caution: Refer to User’s Guide and accompanying documentation.

Caution: Refer servicing to qualified service personnel. (For products
certified by Underwriters Laboratories.)

Important Safety

Considerations

Place the product in a location where it cannot harm the patient should it fall
from a shelf or other mount.

Do not autoclave this product.
Inspect the power adapter cord periodically for fraying or other damage, and

replace the adapter as needed. (The power adapter is not a serviceable part;
however, the detachable power cord used with the Universal Power Adapter
is replaceable). Do not operate the apparatus from mains power with a
damaged power adapter cord or plug.

Frequent electrical and visual checks should be made on cables and
electrode wires. Broken or frayed electrode wires, or loose snap-fittings may
cause interference or loss of signal. Particular attention should be paid to the
point at which the wire enters the snap-fittings, since flexure will eventually
cause breakage of strands at this point.

Avoid electrosurgery burns at monitoring sites by ensuring proper
connection of the electrosurgery return circuit. If the electrosurgery return
electrode is improperly connected, the other patient-connected monitoring
electrodes and transducers (particularly ECG electrodes and temperature
probes) will serve as return paths for the high-frequency energy. This is
especially true for older electrosurgery units which have the return circuit
deliberately earth-grounded. For improved safety, never deliberately ground
the return circuit of an isolated-output electrosurgery unit. If necessary,
operate the monitor on battery power only to prevent a return to earth
ground through the monitor.

To assure operator safety during defibrillation, keep the discharge paddles
away from ECG and other electrodes, as well as other conductive parts in
contact with the patient. During defibrillation, always avoid contact with any
accessories, such as cables and sensors, connected to the Propaq’s left side
panel. For additional safety precautions, refer to the defibrillator operator’s
manual.

To ensure patient safety, the conductive parts of the ECG electrodes
(including associated connectors) and other patient-applied parts should not
contact other conductive parts, including earth ground, at any time.

Do not operate this product in the presence of flammable anesthetics.
Explosion can result. This product must only be operated in strict
conformance with local fire prevention regulations.

ii 810-0334-01 Calibration/Maintenance Manual

Propaq 100-Series Monitors Safety Summary

NOTE

Within certain governmental jurisdictions, all interconnected
accessory equipment must be labeled by an approved testing
laboratory. After interconnection with accessory equipment, risk
(leakage) current and grounding requirements m ust be maintained.

To ensure patient safety, use only accessories recommended or supplied by
Protocol Systems, Inc. For a list of those accessories, see the Protocol
Products and Accessories book (PN 810-0409-00) that accompanies the
Users Guide.

Do not autoclave accessories unless the manufacturer’s instructions clearly
approve it. Many accessories can be severely damaged by autoclaving.

To ensure conformance to risk (leakage) current requirements when
operating from an ac mains power source, use only a Protocol Systems’
503-0002, 503-0053, or 503-0054 power adapter.

Pour limiter le courant de fuite conformément aux exigences lorsque
l’appareil est branché au secteur, utiliser seulement un bloc d’alimentation
de la série 503-0002 503-0053, 503-0054.

A product that has been dropped or severely abused should be checked by
qualified service personnel to verify proper operation and acceptable risk
(leakage) current values.

While under warranty, the Propaq should be serviced only by Protocol
Systems’ service personnel. Service documentation is available from
Protocol Systems, Inc. to aid the biomedical engineer during post-warranty
period service.

Component replacement and internal adjustments must be made by qualified
service personnel only.

Propaq 100-Series Monitors Section 2—Installation and Service

Recommended

Service

The Calibration/Maintenance Manual provides instructions and information
for technicians to repair the Propaq at the replaceable module level.
Replaceable modules include circuit boards, large hardware items, such as
the air pump, check valve, chassis parts, and other parts easily replaced
without desoldering of surface-mount components and other small hardware.
Module-level repair allows monitor repair in minimal time and for a
nominal price for the replaceable module.

Because of the specialized equipment and knowledge required to
manufacture and repair the Propaq, Protocol Systems, Inc. recommends that
only Protocol’s authorized repair facilities provide component-level repair. If
repair by other than Protocol’s authorized repair facilities is required, such a
facility must have the necessary equipment to service and repair surface
mount technology (SMT) electronics as well as the specialized equipment to
service Propaq monitors. The Schematics & Drawings Set (orderable as
810-0334-10) and appropriate option section (SpO
PN 810-0334-30, or CO

PN 810-0334-40) provides schematics, parts lists,

Functional

V erification

The functional verification procedures verify proper operation of the
monitor, oximeter, and printer. This procedure should be performed at
intervals or conditions listed in Table 2-1.

Self Test Many functions, such as alarms, waveform and scale sizing, and printer

control, are software operations. Since system software is automatically
checked during the monitor’s power-up self-test, all software functions work
normally if no error messages appear during the power-up sequence. (Some
error messages indicate hardware failures.)

The Service Menus Service Menus are provided to facilitate functional verification. The Service

Menus (Figure 2-1) contain several functions for testing and verifying the
Cuff channel, display, invasive pressure channel (models 104 and 106 only),
and printer. During the functional verification procedure, the Service Menu
functions will be accessed to perform necessary tests.

Procedure NOTE

If the monitor has been stored for longer than one month
without the monitor connected to the ac adapter (for
recharging), the battery voltage should be checked. The battery
may need to be replaced if it cannot hold a charge.

The functional verification must be done only when the monitor is fully
assembled. Equipment required to perform this procedure is shown in Table
2-2. Most items not commercially available can be made according to the
information in Appendix A.

2-6 810-0334-01 Calibration/Maintenance Manual

NOTE

If you plan to use a Dynatech/Nevada model 213A, 215A, or 217A
Patient Simulator to simultaneously simulate ECG and invasive
blood pressure, see Appendix B for important information.

If the monitor did not pass the functional verification, or when it is time to
do a routine calibration, see the Calibration Procedure in Section 3.

Functional verification and safety checks must always be done after monitor
disassembly or calibration, or whenever there is a question about the safety
of the patient functions.

NOTE

Before starting the verification procedures, charge the battery
for at least 8 hours with the monitor turned off. (Charge for 12
hours if a Printer or SpO

module is attached.)

CO2Functional

Verification

This procedure verifies CO2accuracy. If the verification test results are
within specifications, board calibration is not required.

Functional verification and calibration procedures require calculations of
local barometric pressure and partial pressure of the test gas source (in
mmHg) to compare to Propaq displayed values.

Determine Local Barometric Pressure

1. Determine local altitude above sea level. For worldwide locations, obtain
altitude from local geological maps (U.S.G.S. maps in the United States)
or other local references. Refer to Table 2-3 to determine local
uncorrected pressure (LUP) for established altitude.

2. Determine ATIS reported pressure (inches or millimeters of Hg).
For U.S. locations, consult local telephone directories to obtain the

Automated Terminal Information Service (ATIS) number, which is
typically listed under United States Government Offices, Department
of Transportation, Federal Aviation Administration, Air Traffic
Control Towers. Among various statistics reported is the “altimeter”,
which is given in four integers. The four digits represent the
barometric pressure as referred to sea level, in units of inches of
mercury, with an assumed decimal point occurring between the
second and third numbers.

For worldwide locations, equivalent altimeter statistics, in millimeters
of mercury, may be obtained from local agencies.

NOTE

The difference in altitude between the calibration site and the ATIS
site should not be greater than 30 m or 100 ft.

3. Determine local barometric pressure using LUP and ATIS. Apply the
ATIS and LUP values to the following formula to calculate the local
barometric pressure (mmHg):

Local Barometric Pressure =

•

0.033421

0.00131579

LUP•ATIS (ATIS in inches of mercury)

•

LUP•ATIS(ATIS in millimeters of mercury)

EXAMPLE 1:

Step 1: The user’s altitude is 5000 feet. The LUP from Table 2-3 is 632.35.

Step 2: The reported ATIS is 30.09 (“Altimeter: three zero zero niner.”)

Step 3: Multiply 632.35 (LUP) times 30.09 (ATIS) times 0.033421

Local Barometric pressure = 635.92 mmHg

EXAMPLE 2:

Step 1: The user’s altitude is 1000 meters. The LUP from Table 2-3 is

674.11
Step 2: The reported ATIS is 764.29 mmHg.
Step 3: Multiply 674.11 (LUP) times 764.29 (ATIS) times 0.00131579

Local Barometric pressure = 677.92 mmHg

accuracy. If the verification test results are

2

within specifications, board calibration is not required. If verification test
results exceed specification limits, calibration as instructed in Section 3
MAY or MAY NOT be required-see Table 2-4 for possible sources of errors
in testing. Before proceeding to calibration, check test parameters as
indicated in Table 2-4 to minimize errors.

1. Connect a CO

sensor with airway adapter to the Propaq CO2input

2 .Power the Propaq on and use the menu keys to disable the patient

alarms. Set the CO

measurement UNITS to millimeters of mercury

2

(mmHg).

3. Allow the monitor and sensor to warm up for a minimum of 15 minutes.

NOTE

Possible errors may be caused if the area has high background CO

2

levels or if CO2has been forced outside of the airway adapter and
into the sensor itself. To reduce background CO

level, the area

The following safety tests should be performed after any servicing which

requires opening the monitor.

Patient Isolation

Safety Checks

Patient Leakage (Risk) Current Test

Check leakage currents using a Dynatech/Nevada (formerly Neurodyne­Dempsey) 431F-1D Safety Analyzer or its equivalent. The source current
should not exceed 10 µA rms. The sink current, measured between the
isolated patient connections (ECG) and the dc power input connector of the
monitor, should not exceed 20 µA rms. See the analyzer’s operator’s manual
for the proper safety check procedure. Table 2-5 lists the proper connections
between the monitor, power adapter, and the safety analyzer for each test.
Note: because of the all-insulated construction of the monitor, the Enclosure
Leakage Current Test to ground is not performed.

Dielectric Strength (Hi-Pot) Test

Because of the close spacings of the monitor’s internal components and the
critical positioning of sheet insulation within the monitor, Protocol Systems
recommends that a dielectric strength test be performed following any
procedure in which the monitor is opened.

This test requires specialized equipment which may not be available at
hospital repair facilities. If that is the case, Protocol Systems, Inc., will
perform the safety test for a nominal charge with one-day turnaround. See

Repair and Upgrade Support at the beginning of this Section.

WARNING

The Hi-Pot test is extremely hazardous. Only qualified service
personnel should perform this test. Conduct the test only on an
insulated table top, away from other persons and equipment.

Screen

Messages

Equipment Alerts

and Caution

Messages

Messages may appear on the display to inform the operator of some
functional condition. Those messages are explained below.

Equipment alert conditions result in both 1) an audible alarm tone which
sounds until the alert condition is corrected, and 2) an equipment alert
message, which appears in the equipment alert window on the display. Some
equipment conditions also result in a caution message alternating with the
time of day, cuff, or temp numerics to the left of the heart rate.

CHECK ACUITY/DATA COMM CONNECTION. This message appears

when the Acuity cable is unplugged from the Propaq. To cancel, press the
DISABLE button. Pressing the NET OFF button (in the SYSTEM Menu)
prior to unplugging the Acuity cable does not prevent this equipment alert
from appearing. Software V7.01 and up only.

LOW BATT. This message indicates low battery voltage. Plug the Propaq

into ac mains using the power adapter to recharge the battery.

SIMULATING. INSERV mode is activated; simulated patient data is being

displayed and saved in trend memory. To deactivate, turn Propaq off and
then on.

PROGRAM FAULT: SETTINGS LOST, TIME/DAY RESET. If this

message appears when the Propaq is first turned on, it generally indicates a
drained lithium battery. The monitor can be used, but all settings will return
to factory defaults each time the monitor is turned off and on. Replace the
lithium battery as soon as possible.

ECG Messages ECG FAULT. Indicates ECG lead fault for one or more leads. An

equipment alert window appears, indicating which lead or leads are faulty.
Check ECG lead wires, electrodes, and cable.

Calibration/Maintenance Manual 810-0334-01 4-1

Section 4—Troubleshooting Propaq 100-Series Monitors

Invasive Pressure

Messages

The invasive pressure channel can produce messages that appear in the time
of day window, the blood pressure numerics window, and the equipment
alert window.

The following messages appear in the blood pressure numerics window.

Px NOT ZEROED. This message appears the first time a transducer is

connected to the monitor. It indicates that no zero reference has been
established. The monitor displays the pressure waveform, but to protect
against erroneous readings, the pressure waveform scale is not displayed.

Px ZEROING. This message briefly appears as the transducer is being

zeroed.

Px ZEROED. This message appears after the zero value has been accepted.

It remains for eight seconds and is replaced by the current pressure values.
After zero acceptance, the pressure waveform scale appears.

Px ZERO REJECTED. This message appears after unsuccessfully

attempting to acquire a zero reference value. The message remains until the
CANCEL button is pressed. Causes of unsuccessful zeroing may include an
incompatible or defective transducer or cable.

Px CANCELED. This message appears after the CANCEL button is pressed

and remains for eight seconds.
The following caution messages can appear in the time of day window

above the heart rate.

P1 FAULT (P2 FAULT). One or both of these messages appear when a

transducer fault is detected. An equipment alert also occurs. (See the
following equipment alert messages.)

The following equipment messages can appear in an equipment alert
window. A caution message also appears in the time of day window.

TRANSDUCER NOT DETECTED. This message appears when the Propaq

detects that a transducer connection is broken. The transducer connections
and the transducer should be checked.

TRANSDUCER SHORTED. This message appears when the Propaq senses

a short in the transducer. The transducer should be replaced.

INCOMPATIBLE TRANSDUCER. This message appears when the Propaq

has the Hewlett-Packard Connector-Compatible option, and an HP1290A
invasive pressure transducer has been plugged in. The HP1290A is not
compatible with this option; use only approved transducers listed in Section
6 of the Propaq Users Guide for Version 8 software.

NOTE

Since both pressure channels use the same hardware, an
incompatible transducer plugged into one channel will likely cause
false readings on the second channel as well, even if a compatible
transducer is plugged into the second channel.

4-2 810-0334-01 Calibration/Maintenance Manual

Propaq 100-Series Monitors Section 4—Troubleshooting

Cuff Messages The following cuff messages can appear in the equipment alert window. A

CUFF FAULT caution message also appears in the CUFF window (to the

right of the time of day window).

CUFF FAULT: LOW BATTERY, CUFF DISABLED. The battery lacks

sufficient voltage to be able to operate the CUFF channel. Connect the
Propaq to the ac power adapter.

CUFF FAULT: CALIBRATION ERROR, CUFF DISABLED. The Propaq

continually recalibrates the cuff channel to ensure it can properly make cuff
determinations. If this message momentarily appears and then is removed,
the cuff channel was able to calibrate itself and the cuff channel is properly
operating. If this message continuously appears, the cuff channel could not
be properly calibrated and must be disabled using the DISABLE button.
Once the cuff channel is disabled, normal monitor operation continues, but
the cuff channel cannot be used. Repair is required.

CUFF FAULT: MEASUREMENT TIME OUT. A valid cuff measurement

could not be determined within 3 minutes. This could be due to patient
motion, arrhythmia, or other environmental influences such as transport
vibration. Try the measurement again.

CUFF FAULT: EXCESSIVE ARTIFACT. Too much patient motion, patient

arrhythmia, or sources of external cuff movement can cause this message.

CUFF FAULT: NO PULSES DETECTED. The cuff may not be on a

patient or properly applied to the patient.

CUFF FAULT: NO CUFF. During cuff inflation the detected pressure did

not sufficiently rise. Check that the cuff connection is tight, and take the
measurement again.

CUFF FAULT: NO VALID BLOOD PRESSURE FOUND. The Propaq

cannot process the measurement data it acquired. Patient motion, arrhythmia,
or outside environmental influences such as transport vibration can cause
this message.

CUFF FAULT: KINKED HOSE, CHECK HOSE. The Propaq could not

properly inflate the cuff. Check for a kinked hose between the monitor and
the patient.

CUFF FAULT: BLOCKED VENT. The pressure in the cuff cannot be

vented to the atmosphere. Inspect the vent hole for blockage.

CUFF FAULT: AIR LEAK, CHECK HOSE. The Propaq could not

properly inflate the cuff. Check the hose and cuff for obvious leaks, such as
the O-rings in the hose connections.

CUFF FAULT: WEAK PULSES, CAN’T FIND SYS/DIAS. There are not

enough pulses to determine the systolic or diastolic pressures, but a mean
pressure is available. Try reapplying the cuff after squeezing as much air
from it as you can, and then take another measurement.

CUFF FAULT: OVERPRESSURE CONDITION, CHECK HOSE.

Occasionally high cuff pressures, caused by patient motion, can create leaks
in old hoses or bladders. This same type of patient motion can also activate
the Patient Overpressure Safety Circuitry, which then disables the pump and

Calibration/Maintenance Manual 810-0334-01 4-3

Section 4—Troubleshooting Propaq 100-Series Monitors

removes pressure from the cuff. When either case occurs, this equipment
message is displayed. Check the hose, press DISABLE, and try taking
another measurement.

CUFF FAULT: OVERPRESSURE CONDITION, CYCLE POWER.

If the Patient Overpressure Safety Circuit (Recharger Board) has been
activated, this message is displayed. This message is displayed several
seconds after the beginning of an attempted CUFF measurement, or if the
pressure remains above 5 mmHg for more than 2 minutes after an attempted
CUFF determination has ended. The cuff channel is disabled and the Propaq
must be turned off, then back on before the cuff channel can be used. If this
message reappears after cycling power, service the Propaq.

The following messages can appear in the cuff status window (the upper
right corner of the normal status window area).

CALIBRATING. The CUFF channel is running an internal calibration.

Temperature

Messages

The following messages can appear in an equipment alert window. A
temperature caution message also appears in the temperature numerics
window when one of these messages appears.

PROBE NOT DETECTED. This message occurs when the Propaq has

successfully measured temperature and a probe is disconnected. Reconnect
the probe and acknowledge the equipment alert by pressing any menu key.

PROBE SHORT OR OUT OF RANGE. This message usually indicates a

probe problem. However, the temperature being measured may be beyond
the range of the probe or the range of the Propaq. If the probe is correctly
applied to a patient who you believe has a measurable temperature, replace
the probe.

CALIBRATION ERROR, TEMP DISABLED. This message appears when

the Propaq has detected that the temperature circuitry common to all
temperature channels is out of calibration. (This occurs when the values
obtained during auto calibration check do not match those obtained during
auto calibration.) The temperature channel is disabled until the Propaq is
repaired.

Fatal Error

Codes

Fatal errors are errors, detected by software, that indicate the Propaq is no
longer able to function properly and must be returned to Protocol for service.

When a fatal error is found, the software attempts to put the error message
and its number on the Propaq display. All monitoring functions are locked
out. Fatal errors are therefore distinct from equipment alerts, which permit
reduced monitoring capability.

Fatal errors are indicated in the following format:

x - yyy

where:

x = 0 indicates a problem found by the Display Control Processor

(DCP), i.e. non-isolated, section of the Propaq Main B oard.

x = 1 indicates a problem found by the Data Acquisition Processor

(DAP), i.e. isolated, section of the Propaq Main Board.

x = 2 indicates a problem found by the Printer Control Processor

on the Printer Main Board.

x = 3 indicates a problem found by the SpO

(SCP) on the SCP Board.

Control Processor

x = 5 indicates a problem found by the Main Stream Processor

(MSP) on the MSP Board.

yyy indicate specific types of problems. Detailing the nature of

these problems is beyond the scope of this manual.
(Furthermore, these yyy codes change from one software
version to another.) Contact Protocol Systems, Inc. for more
details and/or send the monitor to an authorized Protocol
repair center for repair.

Propaq monitors are manufactured with static-sensitive CMOS
devices. All calibration, service, and repair must be done at a
static-protected work station. Failure to protect against damage due
to static discharge m ay reduce monitor operation life and increase
repairs. Any time the monitor ’s casing is opened, the monitor
should be placed on a static-protected work area.

Safety Tests Whenever the monitor is opened for calibration or repair, a leakage current

safety check as well as a hi-pot test should be performed. Instructions for
performing these safety tests are located in Section 2, Installation and

Service.

The air filter keeps the air to the cuff relatively clean. If the filter becomes
clogged with accumulated dust, smoke, or other debris, the air pump will not
be able to inflate the cuff.

The filter is located inside the back half of the monitor casing (Figure 5-4).
Exact placement varies with different models of left side panels. It is tucked
into the back half close to the bleed valve, but can easily be replaced after
the casing has been separated.

1. Open the monitor as described earlier.

2. Reach into the cavity where the filter is located and slide out the filter.

3. Remove the tubings from the filter and attach a new filter.

4. Carefully tuck the filter and tubing back in place.

Tubing

Refer to Section 7, Diagrams, Figures 7-47 and 7-48 (partial 824-0230-XX,
Sheets 4 and 5) for plumbing layouts and lengths of tubing. Use the
plumbing configuration appropriate to the side panel option installed. If
plumbing must be replaced, see Section 8 for part numbers.

NOTE

It is norm al for the internal plumbing to darken over tim e from the
dry graphite lubricant expelled from the pump.

Air problems can be due to restricted air flow or air leaks. Restricted air
flow can be due to blocked tubing, a clogged air filter, or more likely,
pinched tubing. Air leaks can be due to tubing and fittings, cuff overpressure
valve, check valve, O-ring gaskets in the cuff hose fittings, or the bleed
valve.

If the monitor displays

Air system integrity in the CUFF channel is essential to accurate
measurements. Leaky cuff fittings or air bladder can cause cuff error
messages and erroneous cuff measurements. A leak rate test described in the
CUFF Channel Functional Verification procedure, Section 2, can help
identify air leaks.

WARNING

Use of CUFF channel with leaking cuff hose fittings may result
in inaccurate non-invasive blood pressure measurements.

Routine wear to the O-ring gasket located within the threaded fitting on the
cuff hose requires occasional replacement of the gasket to ensure system
air-seal integrity. Replace gasket according to the following instructions.

1. Disconnect the cuff hose from the monitor's cuff connector.

2. Using pliers, pull off the metal fitting from the cuff hose as shown in
Figure 5-6.

3. Using cutters, cut approximately 1/2" off the cuff hose.

Removing Main

Board

This section provides instructions on removing and installing a Main Board.

CAUTION

Work only at a static-protected work station while disassembling
the Propaq.

The Main Board is secured to the Propaq front chassis by five screws. When
removing the Main Board, note the location of cables and screws and screw
lengths. Handle the protective insulating paper carefully to avoid damaging
it.

1. If an expansion module is attached to the monitor, separate the two

according to the procedures in Separating Expansion Module from
Monitor in this section.

2. Open the monitor as described in Opening the Monitor in this

section.
Be sure to disconnect the pressure transducer tubing before opening

the monitor more than two inches.

3. Disconnect all cables from the Main Board (Figure 5-8).

4. Remove the five screws securing the Main Board to the front
chassis. Note that the two longer screws hold the plastic support
spacer.

Do not attempt to remove the Main Board yet. A lthough the Main
Board is not secured to the front chassis, it is still connected to the
Main Interconnect board by one or two flexible cables on the back
side of the board.

5. Lift the Main Board about two inches.

CAUTION

The flexible, cables depending on type, to be removed in the
next step have pin connectors that can become bent if the
cables are improperly removed.

6. Reach under the Main Board and carefully disconnect the flexible cable
by using tweezers or needle-nose pliers to pull the cables straight down
away from the Main Board.

Take care not to bend the pins on the ends of the cables.

7. Carefully lift out the Main Board.
Key contact areas are located on the opposite side of the Main

Board. Flexible key contacts from the front panel buttons often
“stick” to the Main Board as it is removed. These flexible contacts
should be removed from the board and set aside.

8. For EL display monitors—to gain access to the components on the
back side of the main board, you must also remove the ESIS shield
board, and/or the small paper insulator.

5-12 810-0334-01 Calibration/Maintenance Manual

Propaq 100-Series Monitors Section 5—Replacement Procedures

Fig. 5-8. Main Board Screws, Connectors and Cables

The nylon rivets that hold them may be removed by pushing the
center pin back through the spread ends of the rivet with the blade
of a small screwdriver until the spread ends relax enough to allow
the shield board or insulator to be removed. The center pins of the
rivets do not have to be completely removed to achieve this, only
lifted about 0.075". The ground wire connection between the ESIS
shield and main boards must be unsoldered as well. If you are
swapping a new main board for the old one, you must also remove
the nylon bumper located between the transformer and the opto
isolators. The ESIS shield board, paper insulator, bumper and rivets
must all be replaced, or transfered to a new board. Refer to Section
7, Diagrams, Figure 7-42 (partial assembly drawing 824-0211-XX,
Sheet 4).

9. For LCD Display monitors—to gain access to components on the back

side of the main board, you must first remove the large paper insulator
and nylon hardware and save them for return to the old main board, or
for use with a new main board. Refer to Section 7, Diagrams, Figure
7-43 (partial assembly drawing 824-0218-XX, Sheet 4).

CAUTION

When handling the Main Board, do not touch the button contact
surfaces. These surfaces should remain clean and oil-free. If you
do touch them, clean them with a cotton swab dipped in
isopropyl alcohol or freon.

1. For EL display monitors—When installing the EL display main board.
Refer to Section 7, Diagrams, Figure 7-42 (partial assembly drawing
824-0211-XX, Sheet 4).

– the large paper insulator is in place and properly fastened to the

Main Interconnect Board with the two plastic fasteners,

– the ESIS shield board and small paper insulator are properly

fastened to the back of the main board,

– the ESIS shield ground wire is soldered,
– the nylon bumper is in place.

2. For LCD display monitors—When installing the LCD display main
board. Refer to Section 7, Diagrams, Figure 7-43 (partial assembly
drawing 824-0218-XX, Sheet 4). Check that the large protective paper
insulator is wrapped around the main board, and that the nylon screws
and washers are properly mounted.

3. Set the five flexible key contacts in the openings to the pushbutton
housings. The contacts should be centered on the button with the
protrusion entering the button cavity.

Take care that key contacts do not fall out of place when continuing
this procedure.

4. Carefully connect the flexible cables to the Main Board.

NOTE

EL display flex cables must be properly Z-folded as shown in
Section 7, Diagrams, Figures 7-44 and 7-45 (partial assembly
drawing 824-0226-XX, sheets 1 and 2) to preserve EMI and
HI-POT performance.

5. Check the routing of the alarm LED cable as shown in Figure 5-8.
The routings of these cables are critical to prevent pinching of the

cables when the Main Board is secured to the front chassis.

6. Set the Main Board in place, watching the alignment of the flexible key
contacts and Main Board.

NOTE

Using tweezers in the next steps to place the screws can make s crew
placement easy.

Propaq 100-Series Monitors Section 5—Replacement Procedures

CAUTION

Use caution when positioning the plastic brace and tightening
the screws, as described in the next three steps, to avoid
damaging the U700 oscillator located under the brace (see
Figure 5-8).

7. Place the screws in the Main Board, beginning with the two one-inch
screws that go through the plastic brace.

8. Before tightening the screws, check that the brace is in place (not caught
on the lip of U700) and check the routing of the alarm LED cable.

9. Tighten (7 in-lbs) the screws securing the Main Board.

10. Set the Propaq rear chassis next to the front chassis and reconnect all
cables to the Main Board.

11. Close the monitor as described in Closing the Monitor in this section.

NOTE

To preserve EMI performance, the portion of the large paper
insulator sheet with the foam section on it must be between the
main board and the cables that go from the Main board P3, P4, P5
to the rear chassis.

Replacing EL

Front Panel

Components

12. If an expansion module was attached, re-attach it as described in

Attaching the Expansion Module in this section.

The EL Front Panel components discussed here are referenced in Section 7,
Diagrams, Figures 7-44 and 7-45 (partial assembly drawing 824-0226-XX,
sheets 1 and 2).

CAUTION

The EL Display Subassembly cannot be removed without the
possibility of causing damage to the electrically-conductive inner
surface of the EL display filter.

The conductive silicone O-ring gasket between the EL display
module and display filter tends to remove the delicate gold
coating from the filter when the gasket is peeled up.
Furthermore, the gasket seems to stick equally well to the
display module and filter, so that where separation will occur is
uncertain. If electrical contact with the filter is degraded
sufficiently, the display’s EMI may interfere with ECG and/or

monitoring if their patient cables pass near the display.

Replacing the

Side Panels

Removing Side

Panels

Propaq side panels are complete assemblies requiring only to be set in place,
secured, and the cables or plumbing connected.

Side panels are sealed to the Propaq rear chassis with an adhesive O-ring
gasket. A new gasket is provided with the new side panel kit. Refer to
Section 7, Diagrams, Figure 7-46 (partial 824-0230-XX, Sheet 3) when
removing or installing side panels.

1. Open the monitor as described in Opening the Monitor in this section.

2. To Remove Right Side Panel—remove the Recharger Board as
described in Removing Recharger Board in this section; cut and
remove the tie wrap securing the coil connected to the side panel.

Remove the two right side panel clamps. They can be removed by
inserting the end of a needle-nosed pliers in the small hole in the
end of the clamp and pulling outward. See step 4.

3. To Remove Left Side Panel—disconnect plumbing at the pump and
valve; disconnect the cables between side panel and Main Board.

Remove the U-shaped clamp that secures the left side panel
assembly. Place the end of a flat-bladed screwdriver between the
metal clamp and the side panel assembly and rotate the screwdriver
to loosen the clamp. Using a long-nosed pliers, slide the clamp free.

4. Carefully press the side panel out of the rear chassis. There is an
adhesive O-ring gasket around the side panel which requires
considerable force to separate. DO NOT pry against components!!

5. If replacing the left side panel, disconnect all plumbing from the side
panel. Note cable routing for reinstallation.

Save the plumbing for reconnection to the new side panel.

Installing Side

Panels

Calibration/Maintenance Manual 810-0334-01 5-19

1. Clean all O-ring gasket material from the rear chassis where the side
panel is to be installed. (The adhesive side of “duct tape” can be used to
pull away old gasket residue.)

2. On the new side panel, remove the protective paper from the gasket
attached to the side panel.

Section 5—Replacement Procedures Propaq 100-Series Monitors

NOTE

Uncovering the protective paper exposes the adhesive on the O-ring
gasket. Do not touch or otherwise contaminate the adhesive, or the
adhesive may not properly seal the side panel.

3. Set the side panel in place. Slightly bend up wires at the left side panel
P1 and P2 pressure connector pins to allow proper fit.

Make sure the side panel sets all the way in place (it should be
flush with the exterior of the rear chassis). If not properly fitted, the
clamp securing the side panel will not be allowed to seat.

4. Apply slight pressure to seal the side panel in the rear chassis.

CAUTION

Do not force the clamp in the next step. Forcing it may damage
the side panel or rear chassis.

5. Carefully slide the clamp(s) in place. Detent(s) must press against plastic
chassis.

If the clamp requires excessive pressure to slide in place, remove the
clamp and check the side panel to be sure it is completely seated.

6. Connect all plumbing and cables. Refer to Figure 7-1 and Section 7,
Diagrams, Figures 7-46, 7-47, and 7-48 (partial 824-0230-XX, Sheets 3,
4, and 5) for proper connections.

7. If installing the right side panel, install a new tie wrap inside the rear
chassis, dress coil leads as shown in 824-0230-XX, Sheet 5, and secure
the coil to the side panel.

To preserve EMI performance the cables must be routed as follows:

– the cables leading to P3 and P5 of the main board must be routed

over the top of the right side panel assembly

– the cable to P4 of the main board must be routed under the

bottom of the right side panel assembly

Install the Recharger Board as described in Installing Recharger
Board in this section.

8. Close the monitor as described in Closing the Monitor in this section.

9. If an expansion module was attached, re-attach it as described in
Attaching the Expansion Module in this section.
