2.4. HOST PORT
CONNECTOR (REAR
PANEL)
Important! All host port signals are NON-ISOLATED
and should be connected to equipment conforming to
IEC 601-1 ONLY. Where isolation of data
communication is required, the Critikon isolated level
converter should be used. If external alarm control is
required, Critikon part number 487208 (Isolated
Remote Alarm Cable Assembly) should ALWAYS be
used. Please refer to the Information Sheet included
with the isolated remote alarm cable for operational
details.
Note: When using remote alarm, the PRO Monitor
should be considered the primary alarm source. The
secondary alarm is used for secondary purposes
only.

SECTION 3. PRINCIPLES OF OPERATION
3.1 INTRODUCTION
This section provides overall theory of operation and
functional description of the DINAMAP PRO Monitor
(hereinafter referred to as PRO Monitor). The PRO
Monitor comes in four different models, as follows:
•
PRO Monitor 100 - It has the capability of
monitoring Blood Pressure (BP) and Pulse
•
PRO Monitor 200 - It has the capability of
monitoring BP, Pulse, and Temperature
•
PRO Monitor 300 - It has the capability of
monitoring Blood Pressure (BP), Pulse, and
SPO2
•
PRO Monitor 400 - It has the capability of
monitoring BP, Pulse, Temperature, and SPO2
3.2 OVERALL
PRINCIPLES OF
OPERATION
The following paragraphs provide a general system
interface relationship. The general block diagram is
located in Figure 3-1.
The PRO Monitor is a portable unit that receives input
power from an external AC source, external DC
source, or internal rechargeable battery.
When the ON/OFF button is pressed, the Main Board
is brought out of a sleep mode and turns on the power
regulators. The power regulators provide conditioned
power from one of the input power sources: AC
Mains, External DC, or the Lead Acid Battery. The
regulated power is routed to the Printed Wiring
Assemblies (PWAs) via the cable harnesses. Once
the Pro Monitor is energized, a self-test is performed.
The self-test automatically tests the main functions of
the PRO Monitor. Failure of the self-test will set the
PRO Monitor into a fail-safe mode with an audio
alarm.
Under normal operating condition, the PRO Monitor is
ready to record the patient vital signs using three
3-3
external attachments: the temperature probe, SPO2
sensor, and cuff. Interface with a central station or
other device is accomplished through the host
communication port on the back of the Pro Monitor.
3.2.1 SPO2 (Model 300 and 400)
The SPO2 probe has a built-in sensor. When the
SPO2 sensor is attached to the SPO2 connector and
patient, the probe senses the heart rate and oxygen
saturation. These analog signals are routed to the
SPO2 PWA. The analog signals are analyzed on the
SPO2 PWA. The results are digitized and sent to the
Main Board via opto couplers. The couplers provide
for patient isolation as well as serial data interface.
The Main Board temporarily stores the data and
routes it to the appropriate displays and/or printer.
A reset signal to the SPO2 PWA is also provided so
that the power up sequencing is corrected. If the
SPO2 circuit quit communicating to the Main Board,
the Main Board will attempt to reset the SPO2 PWA.
3.2.2 Cuff Blood Pressure (BP) and Pulse
When the cuff and hose are attached to the Pro
Monitor and Non-Invasive Blood Pressure (NIBP)
determination is initiated, the pump inflates the cuff.
Pressure transducers PT1 and PT2 monitor pressure
information. The pneumatic manifold has two valves,
which are used to deflate the cuff. Valve control is
through the Main Board. Once determinations are
made for the systolic BP and diastolic BP, the Main
Board calculates the pulse rate/Mean Arterial
Pressure (MAP). The results are then displayed on
the front panel (seven segment Light Emitting Diodes
(LEDs)) and sent to the printer.
The Pneumatic Valve/Manifold (PVM) device has an
overpressure sensor built-in to protect against overinflation. If an over-inflation condition occurs, the
OVERPRESSURE signal is routed to the PVM to
release the air pressure. The Main Board also,
generates an alarm condition with the speaker
sounding and a message in the Liquid Crystal Display
(LCD).
3.2.3 Temperature (Model 200 and 400)
When the TEMPERATURE probe is attached to the
temperature connector and patient, TEMP input is
3-4
routed to the Main Board. This input represents the
temperature to be measured. The Main Board
converts the TEMP signal to a DIGITAL signal. During
the conversion, the Main Board determines the
patient temperature. The patient temperature is
distributed as a DIGITAL signal to the LED display or
printer in Celsius or Fahrenheit.
3.2.4 Host Communication Port
The Host Comm Port is used to interface the Monitor
with other electronic devices (a central nurse’s station
or remote alarm device.) Signals can be sent to the
Monitor to initiate blood pressure determinations and
other functions. Patient data can also be retrieved
through this port. For further information, reference
the Dinamap Pro 100-400 Series Host
Communication manual.
3.3 FUNCTIONAL
DESCRIPTION
The following paragraphs provide the functional
interface relationship. The Pro Monitor contains a
number of electrical & electro-mechanical assemblies.
These assemblies are:
•
Power Supply Unit (PSU) PWA
•
PSU Module
•
Main Board
•
SPO2 PWA (optional)
•
Pneumatic control device
•
Liquid Crystal Display (LCD) Assembly
•
Printer PWA w/printer
3.3.1 PSU PWA
The PSU PWA is a low voltage DC power supply. The
PSU PWA is designed to operate from the output of
the AC MAINS PSU module, EXTERNAL DC line
source, or from a 12-volt rechargeable lead-acid
battery. When the PSU PWA receives the
EXTERNAL DC, a portion of that voltage is routed to
an analog input of the Secondary Processor. The
Secondary Processor uses this signal to determine
the available power sources. If a valid external power
source is available, LED lights to indicate that external
3-5
power is available. If an external power source exists,
and a battery source is detected, the Secondary
Processor will send a command to turn on the Battery
Charger circuitry. If there is no external power source
or the external power source is below the required
voltage, the PSU PWA will automatically default to
use the battery. Since the Pro Monitor is now
operating from the battery voltage, a sample of the
battery source is applied to Analog Digital Converter
(ADC) circuit of the Secondary Processor. From this,
the Secondary Processor can determine the charge
state of the battery.
3.3.2 PSU Module
The PSU module is an AC Mains to DC converter.
The PSU module receives AC power from an external
source. When AC INPUT is applied to the PSU
module, the module AC/DC Converter changes the
AC INPUT supply via rectifier circuit to a high voltage
DC. The DC power is then routed through a high
frequency switching converter and regulated to 24
vdc. This supply is connected to the PSU PWA for
further regulation.
3.3.3 Main Board
The Main Board is configured with Programmable
Read Only Memory (PROM), Random Access
Memory (RAM), LED Display, Hard Keys, 16 Bit ADC,
Primary Processor, and Secondary Processor. The
Primary Processor services and controls the Patient
Parameter Interface (PPI) devices and display
backlighting. The Secondary Processor controls the
seven segment LED display, sound generation, real
time clock, and system timing verification. The
processors receive DC power from the PSU PWA.
When the PPI devices transmit analog data to the
Main Board A/D converter, the Primary Processor
perform algorithm calculations. Once all the
calculated parameter values are compiled, the data is
then transmitted to the LCD and printer via Secondary
Processor. Concurrently, the calculated parameter
values are being stored in the non-volatile RAM.
Calibration and other variable settings are stored in
the Electrically Erasable Programmable Read Only
Memory (EEPROM).
3-6
The Main Board backup voltage, derived from either
NiMH battery or an external power source, appears
on the Main Board supervisory circuit. The Main
Board supervisory circuit generates the RESET and
HALT signal for the Primary Processor. It also, allows
EXTERNAL DC voltage to the RAM and Secondary
Processor when the system is ON or battery backup
voltage to power the RAM and Secondary Processor
when the system is OFF.
If the Primary Processor fails to reset its watchdog
timer, the Primary Processor sends a low level on its
watchdog output to the Pneumatic Control Gate Array
Logic (PCGAL). If the Primary Processor detects
system faults or overpressure, it will notify the
Secondary Processor of system failure condition. The
Secondary Processor in turn, sends a FAILSAFE
signal to the PCGAL and Tone Generator. When the
PCGAL receives the FAILSAFE signal, it sends a
DEFLATE signal to the Pneumatic Valves to
depressurize the system to atmosphere. Once the
Tone Generator receives the FAILSAFE signal, it
sends an audio frequency (ALARM signal) to the
speaker. During the failsafe mode the following will
also occur:
•
Parameter monitoring disabled
•
Remote alarm control inactive
•
Graphic LCD displays fault error code
•
Pneumatic safe state (deflate the cuff, pump off)
•
Normal communications interface disabled
•
Hard keys and rotary switch inactive
When a low or high ambient room lighting occurs, the
Primary Processor uses it’s supervisory circuit to
increase or decrease the graphic backlighting,
automatically.
3.3.4 SPO2 PWA (Optional)
The SPO2 PWA provides continuous readings of
oxygen saturation and pulse rate. Additional circuitry
provides power, data communications, and isolation
between SPO2 PWA and Primary Processor.
Patient data received from the finger sensor is filtered,
amplified, and analyzed on the SPO2 PWA. The
3-7
information is sent to the Main Board via the optically
coupled electrically isolated serial connection. The
Primary Processor receives the data and distributes it
to the appropriate display. The data is also sent to the
printer via the Secondary Processor.
3.3.5 Pneumatic Control Device
The Main Board transducers PT1 and PT2 sense cuff
pressure and raw oscillatory information. The analog
signals are amplified, buffered, and sent to an Analog
to Digital (A/D) Converter. The converter changes the
analog signals to digital signals and routes these
signals to the Primary Processor. The Primary
Processor receives the digital signals via the data
interface.
Appropriate valve and pump control signals are sent
from the Primary Processor to the PCGAL. The
PCGAL then generates the appropriate drive signals
to the pump and valves.
If a failsafe mode or overpressure condition occurs,
the PCGAL provides the appropriate control signals to
insure a safe condition, where the cuff vents to
atmosphere pressure.
3.3.6 LCD Assembly
The LCD assembly is used as a message center. It
displays patient vital signs, alarm status, monitor setup, limit violation, BP cycle and the time the data was
received. The Primary Processor controls the LCD
assembly. When the parameter signals are read by
the Primary Processor, it decodes these signals and
routes the digitized signals to the graphic LCD.
The LCD assembly is equipped with a variable
lighting feature for the graphic display. The Primary
Processor controls the lighting feature, automatically.
When a low or medium ambient lighting condition
occurs, the Primary Processor sends a BACKLIGHT
signal to adjust the graphic display lighting with
respect to the room lighting condition. If the lighting
condition is high, the Primary Processor sends a
BACKLIGHT_1 signal to switch off the graphic display
lighting.
3.3.7 Printer PWA w/Printer
The Printer PWA w/printer communicates to the
Primary Processor via Secondary Processor data line.
3-8
The printer receives power from the Main Board via
the Printer PWA. The printer sends a DATA OUT
(CONTROL DATA) signal to the Secondary
Processor to notify of it’s presence. When a print
command is sent to the printer from the Secondary
Processor, the following will occur:
•
CLOCK signal - transfer the data into print
head
•
DATA IN - serial dot to be printed
•
LATCH signal - latch the data stream into the
head
•
STB1-6 - cause the head to print various
sections
Together these signals (CONTROL DATA) cause the
printer to print a graphic hardcopy of the patient vital
sign values and trend data. It also causes the printer
to print hardcopy of error logging and service record
data.
The printer has a built-in sensor to monitor the printer
paper level. When the printer is out of paper, it sends
a PAPER OUT signal to the Secondary Processor.

SECTION 4. GENERAL MAINTENANCE
4.1. INTRODUCTION
This section contains maintenance procedures for the

DINAMAP PRO Series 100-400 Monitor, including description
of the software screens and menus used to adjust, configure
and check the Monitor. Also included are procedures to recalibrate the NIBP, and adjust the overpressure points.
Procedures pertaining to SpO2 and temperature functions
apply only to PRO Monitors equipped with these features.
4.2. FUSES
The PRO Monitor power circuits incorporate five fuses. None
of the fuses are externally accessible. Two mains fuses are
mounted on the AC Mains converter board, and are not
serviceable by user.
If a mains fuse blows, the monitor will not change from battery
power to mains power when it is plugged in to an AC power
source. To confirm a fuse problem, remove the battery, plug the
unit in, and turn it on. If the PRO Monitor does not operate, the
probable cause is an open fuse. Mains fuses should only be
replaced by a qualified service technician.
The other three fuses are:
• FS1 - Self resetting; DC input; PSU board
• FS2 - Self resetting; Battery; PSU board

4.3. PERIODIC MAINTENANCE
Periodic maintenance tasks include cleaning the PRO
Monitor, checking pressure calibration, pneumatic leakage,
pneumatic system overpressure point, the temperature
calibration (PRO Monitors 200 and 400), and verification of
the SpO2 system (PRO Monitors 300 and 400).
4.3.1 Cleaning the Monitor
The exterior of the PRO Monitor may be wiped clean with a
cloth slightly dampened with mild detergents or standard
hospital bactericides.
Cleaning with isopropyl alcohol or similar solvents is not
recommended.
Do not immerse unit.
Do not immerse hoses.
4-3
Do not immerse cuffs without prior application of cuff hose caps.
CAUTION
Moisture or foreign substances introduced into the
pneumatic system will cause damage to the unit.
Calibration equipment should always be kept dry and
clean.
4.3.2 Power Up Checks
When the PRO Monitor is powered up, it conducts a series
of self-tests to ensure that the displays and other functions
are operating normally. Some malfunctions generate fatal
errors and put the Monitor in Failsafe mode. In this mode,
the patient monitoring features are disabled. Other
malfunctions do not interfere with normal operation, but
should be repaired at the next opportunity.
As part of a periodic maintenance routine, observe the
power-up self tests, and service as required.
LED Display Check
All seven segments of the LED bulbs are illuminated during
the power up sequence. The segments light in a sequence
beginning with the upper left segment.
LCD Display and LCD Back Light Check
Observe the LCD during power up. Confirm that all of the pixels on
the LCD display are lit momentarily, and the back light is powered
during initialization. The backlight is only noticeable in a dimly lit
room. Confirm that the display indicates the software version in
inverted format (white on black).
NIBP Calibration Check
If the NIBP system is uncalibrated, the Monitor boots directly
to service mode and displays a service menu. Refer to 4.10
PRO Monitor Calibration Procedures, page 4-17.
Speaker Check
During power up, the audio system generates three short
beeps, followed, after a brief pause, by three more beeps. If
the speaker generates distorted, or no sound, it is faulty.
Remote Alarm Switching Check
When the PRO Monitor is off, the remote alarm switches to an
alarm state. The system clears the alarm state during power
up. If the remote alarm does not change states, it is faulty.
4-4
4.3.3. External DC Supply and Battery
The power indicators on the lower left on the front of the
PRO Monitor show the source and charge status of the
battery. The external power indicator LED continuously
glows green to show the battery is charging.
The indicator flashes every four seconds to show an external
power source is connected, but is not charging the battery. Either a
battery is not installed or the external DC input voltage is too low.
1. Power on, and wait for the Pro Monitor to initialize.
Confirm that the external power indicator is lit and the
battery LED is extinguished.
2. Remove the battery and confirm that External DC LED
on Monitor flashes.
3. Fit the battery and disconnect the external power supply.
Confirm the external power indicator extinguishes, the
battery LED glows yellow, and the battery icon appears
on the LCD, toggling with the time indicator. If the battery
power is low, the battery LED flashes every four seconds, and the battery icon on the LCD changes.
4. Reconnect the external power supply, verify that the
battery LED extinguishes.
4.3.4. Care Of The Storage Battery
It is best to keep the battery charged as fully as practical.
Never store the Monitor with the battery in a discharged
condition. When the battery no longer holds a charge,
remove and replace with one of the same part number.
PRECAUTIONS
To ensure that the battery is ready for portable operation, keep the unit connected to AC mains whenever
possible. Repeated failure to fully charge the battery
significantly reduces battery life. Avoid storing batteries at temperatures above 77° F (25° C). High storage
temperatures can dramatically increase the selfdischarge rate of battery.
4.3.5. Checking NIBP Calibration

seconds, the target pressure value will be displayed in
mmHg on the LCD. The system holds the pressure for
approximately 36 seconds and continues to display the
current pressure on the LCD. Confirm that the pressure has
fallen no more than 5 mmHg.
4.13.6 Printer Test
This test generates a sample printout from the printer. If no paper is
in the printer, the Monitor generates no alarm.

Ensure the printed test page is clear and easy to read.
4.14 ELECTRICAL SYSTEM
SAFETY CHECKS
The PRO Monitor is designed to protect the patient from
exposure to harmful levels of electricity. To ensure the
integrity of these safeguards, use a safety analyzer and feed
253 vac into the system. A current-leakage test must be
performed on every unit whenever the case is opened for
repairs, and before it is returned to clinical service. If the
reading exceeds the maximum tolerance as specified below,
do not return the unit to clinical service.
Normal Polarity
At normal polarity, test open ground and open neutral. The
leakage reading should be <500uA.
Reverse Polarity
At reverse polarity, test open ground and open neutral. The
leakage reading should be <500uA.
Temperature System Leakage (PRO 200 & 400)
Use a temperature plug with the leads shorted and apply
test voltage to the leads. The leakage reading should be
<50uA.
SpO2 System Leakage (PRO 300 & 400)
Use an SpO2 plug with the leads shorted together. The
leakage reading should be <150uA.
Perform these four checks when repairs are completed, and
prior to returning the monitor to clinical service.

SECTION 5. COMPONENT INFORMATION & PART LISTS
5.1. INTRODUCTION
The Critikon PRO Monitor is designed in a modular
configuration, with subassemblies, that can be quickly
and easily replaced. The case breaks down into two
halves: the front case assembly and the rear case
assembly. The PWAs (printed wiring assemblies) and
mechanical assemblies are attached to these and
connected by tubes and cables. Using the Trouble
Shooting hints in Section 4 and the technical
descriptions in Section 3, malfunctions can easily be
isolated to a specific subassembly. Refer to the parts
list in this section for part numbers.
The Front Case assembly includes:
• Main PWA
•
SpO2 PWA
•
LCD assembly
•
Rotor knob and shaft
•
Fascia
The Printer Module subassembly includes:
• Printer PWA (printer interface)
•
Printer
•
Printer housing, door, and door latch
The Rear Case assembly includes:
• Speaker assembly
•
PSU Module (AC to DC Converter)
•
PSU PWA (Low Voltage Power Supply)
•
Pump/manifold assembly
•
Pump bracket
•
Battery door
The illustrations and component information in this
section pertain to the PRO Series Model 400, which
includes all four functions: BP, pulse, temperature
5-3
and SpO2. If a function in not installed on the unit in
service, simply disregard the sections that are not
applicable. The basic disassembly procedures and
replacement part numbers apply to all the models in
the PRO Monitor series.
5.2. GENERAL
PRECAUTIONS
Before beginning disassembly, disconnect the line
power cord from the mains input connector and
remove the rechargeable lead-acid battery.
When working with circuit boards, protect them from
electrostatic discharge. The main PWA contains
microprocessors and memory modules, which can be
easily damaged by electrical surges.
Pay special attention to the ribbon cables and hoses.
When repairs are complete and the unit is
reassembled, ensure that the cable connectors are
firmly attached and the hoses are not pinched or
kinked.
Keep the work area clean. It is easy to scratch the
front plastic display panel with a screw or other sharp
object.
5.3. TOOLS REQUIRED
5mm socket wrench or standard pliers
#1 Philips screwdriver
#2 Philips screwdriver
Small flat-head screwdriver
Needle-nose pliers
Torx drivers sizes T7 and T10
5-4
5.4. BATTERY
Figure 5-1. Rear view. To remove the battery
compartment cover, depress the latch (2) and
push the arrow up. The front and rear case are
secured by screws (1) inside the hand recess.
COMPARTMENT COVER
The battery compartment is covered by a molded
plastic door, which is secured by a latch. The latch
release lever is located at the lower left of the door.
See Figure 5-1.
5.5. REPLACING THE
FASCIA
A common problem with the fascia is fading images
and icons. These are printed on the fascia
membrane, and should stay bright and clear for many
years. Avoid cleaning the equipment with alcohol,
and strong solutions. See Section 1 for the
recommended cleaning agents and procedures.
New fascias are available (see the Parts List, page 516), and the old fascia peels off.
5-5
To prevent switch actuators and the light diffusers
from falling out during the fascia removal place the
monitor on it’s back To remove the old fascia, lift one
corner, and carefully pull the material to separate it
from the front case. The new fascia applies more
evenly to a clean surface and has a more aesthetic
appearance. If residual adhesive remains on the front
case, rub it off. Do not use chemical solvents. They
may damage the plastic.
To apply a new fascia, peel the backing, align the
corners and press the new fascia into place, being
careful not to trap air bubbles between the membrane
and the front case.
5.6. OPENING THE CASE
The front and rear case assemblies are secured by
two Philips screws located inside the hand recess at
the top of the rear enclosure. See Figure 5-1.
To open the unit, remove these two screws. Turn the
unit around, with the front forward, and carefully tilt
the front case assembly forward. The two halves of
the unit are connected at the bottom. When the front
panel is at about 45°, the two halves separate. Be
careful not to stress the wiring connectors when you
separate the front case from the rear case.
5.7. NIBP PNEUMATIC
HOSES
Figure 5-2. Pneumatic system layout. The main BP
readings are derived from transducer PT1. Transducer
PT2 confirms the reading and triggers the overpressure
signal.
5-6
Three pneumatic hoses link the BP cuff, the pump
and the transducers, which generate an analog signal
to calculate the BP readings. If the hoses are not
connected correctly, the Monitor will not operate
properly.
It is also important to make sure that the hoses are
not kinked or pinched when the front and rear cases
are reassembled. Replace the cable tie affixing the
hose to the pump manifold.
5.8. WIRING
HARNESSES
Most of the physical interconnections between the
PWAs and other subassemblies are via cables or
bundled wires. The SpO2 PWA connects directly to
the Main PWA via a 5-way pin connector. The Main
PWA connects to the LCD module via a 20-way pin
connector.
5.8.1. PSU Interconnection
DC power: 2-way (red/black) from PSU Module to
PSU PWA (PL2).

5.9. DISASSEMBLY
PROCEDURES
This section describes how to open the case,
disassemble the chassis and remove the PWAs and
subassemblies. These descriptions and illustration
include the circuit boards, connectors, and equipment
related to BP, pulse, SpO2, and temperature
functions. However, the procedure applies to all PRO
models.
In general, the disassembly must be performed in the
order presented here, as some assemblies may block
access to the screws and connectors, which attach
other assemblies.

5.10.1. Removing the SpO2 PWA
The SpO2 PWA is attached to back of the Main PWA,
and secured with a nylon spacer and two screws, one
of which connects an RFI grounding strip to the Main
board.
1. Remove the nuts on the SpO2 PWA.
2. Turn the front case over and remove the two
screws that hold the SpO2 connector.
3. Pinch the nose of the nylon spacer with the pliers
and separate the SpO2 PWA.
4. The SpO2 PWA plugs into the Main PWA through
2-way and 5-way pin connectors.
5-9
5. Carefully pull the SpO2 PWA until the connector
pins are free from the socket.
If the PRO Monitor is equipped with SpO2, the SpO2
sensor connector must be detached from the front
case before the Main PWA can be removed. If an
SpO2 module is not installed, this port is covered with
a plug.
5.10.2. Removing the Main PWA
The Main PWA is secured to the front case by three
Torx screws through the back of the board and one
retaining clip: two mounts are located at the bottom of
the main board, and the remaining mount is near the
rotor switch. If SpO2 is installed, the two screws at the
bottom are visible through holes in the SpO2 card. In
addition, the SpO2 sensor connector is secured to the
front case with two Torx screws. These are visible in
the SpO2 port at the lower center of the front case.
1. Remove the cable connectors attached to the
Main PWA.
2. Carefully remove the pneumatic hoses from the
cuff connector and pump manifold.
3. Turn the front case over, and remove the two
screws from the SpO2 port at the bottom center.
4. Remove the three screws holding the Main PWA
to the front case.
5. Remove retaining clip by prying it off with small
flat screwdriver.
The Main PWA connects to the LCD subassembly
through a 20-pin connector (SK3), located on the left,
below the rotor switch. Carefully pry the pins on the
Main PWA from the connector on the LCD assembly.
CAUTION: Be careful not to break the temperature
switch arm when removing the Main PWA. Lift the
Main PWA out of from bottom by tilting it.
5.10.3. Removing the LCD Module
The LCD Module is an integrated unit with display
panels attached to a printed circuit board. A latch
molded into the front case, at the top center of the
board, holds it in place. To remove the LCD
subassembly, slip a small flat-head screw driver
under the latch and pry it open.

5.11.1. Removing the Pump Assembly
With the printer assembly removed (See page 5-13),
the two mounting screws on the pump subassembly
bracket are easily accessible. Remove these screws
and separate the pump and valve subassembly from
the brackets. Two lengths of rubber hose on metal
rods help support the pump motor and isolate
vibrations. Be careful not to lose these small rubber
pieces, as they are not glued to the rods.
5-11
5.11.2. Removing the Pump Bracket
The pump assembly bracket must be detached before
the PSU PWA can be removed from position in the
rear case. Unscrew the three Torx screws holding the
metal pump bracket to the rear case. Rubber
grommets are used to absorb vibrations.
5.11.3. Removing the PSU PWA
Disconnect the cables to the printer and the Main
PWA. The PSU PWA is secured to the rear case by
three screws on the board, one located on the front of
the board and two screws into the battery
compartment base through the bottom of the Rear
Case Molding.
Disconnect the DC power input (PL3) from the PSU
PWA, and slide the assembly from the rear case.
5.11.4. Removing the PSU Module
The PSU Module slides on grooves molded into the
rear case.
1. Remove the retaining clip from the plastic molding
at the bottom of the board.
2. Disconnect the shielded power supply cable that
runs from the PSU Module to the PSU PWA.
3. Slide the PSU Module from the rear case.
The PSU module is connected to the mains input.
Disconnect the mains input lines from the AC power
connector.

Housing, 4) Printer Interface PWA.
5.11.5. Removing the Printer Assembly
The Printer is an integrated unit that includes the
housing, door, latch, thermal print head, paper feed,
and interface PWA. The printer subassembly slides
along rails and guides molded into the rear case. A
flexible tab on the printer housing snaps into a slot on
the bottom rail and holds the assembly into position.
1. Detach the cables connecting the Printer PWA to
the PSU and Main PWAs.
Figure 5-6. Location of the opening
in the bottom of the rear case.
2. Access the tab with the blade of a small
screwdriver through the opening between the
printer housing and the rear case at the bottom of
the printer door. It may help to remove the printer
5-13
door. The tab is also accessible through an
opening in the bottom of the rear case, directly
below the printer assembly housing. See Figure
5.6. Insert a small flat-head screwdriver into the
opening and move the tab to the left (towards the
outside of the rear case) to release the printer
housing from the latch.
CAUTION
Do not over flex the printer assembly retention
tab, as doing so may cause the tab to break.
3. When the tab is clear of the slot, slide the printer
housing out of the rear case.
5.11.6. Removing the Printer PWA
The Printer PWA is a small circuit board mounted on
the printer housing and attached to the thermal print
head by a 28-way ribbon cable. This interface also
provides connectors and wire-to-board connections
for other printer functions. Two arms molded into the
printer housing secure the Printer PWA. These arms
fit into matching holes in the board.
1. Disconnect the cables to the PSU PWA and the
Main Board.
2. Remove the Printer PWA from the two plastic
arms on the housing.
3. Release the ribbon cable from the print head with
the lever on the ZIF socket.
5.12. REASSEMBLY
PROCEDURE
Reassembly is a direct reversal of disassembly,
however additional care must be taken to ensure that
all cables and hoses are reinstalled correctly.
If the hoses are connected incorrectly, the Monitor
will not operate. It is also important to make sure that
the hoses are not kinked or pinched when the front
and rear cases are closed.
5-14
The main points to note when reassembling are:
Pay particular attention to the wiring harnesses and
pneumatic hoses, and ensure that all components are
reinstalled correctly.
•
When reassembling the chassis, remember to
reconnect the pump to PL3 on the Main PWA.
•
When reinstalling the Main PWA and the SpO2
PWA, ensure that the pins are properly
inserted into the matching connectors.
•
Ensure that the hoses to the front panel are
not pinched or kinked when the two halves of
the case are closed.
Check calibration per Section 4 before releasing the
Monitor for clinical use. If necessary, recalibrate the
Monitor.
5.13. SAFETY CHECKS
After the case is closed, and before returning a
repaired PRO Monitor to clinical service, conduct a
current leakage test with a safety analyzer, as
described in Section 4.
Any time the case is opened, check the integrity of
the electrical system with a safety analyzer. To pass
these checks, the reading must not exceed the
following limits:
Ground Leakage
Normal Polarity
Open Ground
Open Neutral
<500uA
<500uA
Reverse Polarity
Open Ground
Open Neutral
<500uA
<500uA
Temp Leakage
All leads to temperature probe <50uA
SpO2 Leakage
All leads to SpO2 probe <150uA
