INTRODUCTION

This section provides an introduction to Respironics’ M Series family of sleep therapy products as well ascontact and service training information.

M SERIES OVERVIEWThe Respironics M Series sleep therapy devices are low-pressure, electrically-driven sleep apnea systemswith electronic pressure control for the treatment of adult Obstructive Sleep Apnea (OSA) only inspontaneously breathing patients weighing >66 lbs. (>30 kg). The device’spressure controls are adjusted to deliver pressure support to the patient. TheM Series devices are intended to augment patient breathing by supplyingpressurized air through a patient circuit.

M Series devices available at the time of publication of this Service &Technical Information package are listed as follows:

• REMstar® M Series CPAP Device (no SmartCard®)

• REMstar® Pro M Series CPAP Device

• REMstar® ProE M Series CPAP Device (not available in the Domestic U.S.)

• REMstar® Plus M Series CPAP Device

• REMstar® Auto M Series CPAP Device (C-FlexTM and A-FlexTM Models)

• BiPAP® Plus M Series Bi-Level Device (no SmartCard)

• BiPAP® Auto M Series Bi-Level Device

• M Series Integrated Heated Humidifier

C-FLEX FEATURE

M Series Continuous Positive Airway Pressure (CPAP) sleep therapy devices (listed above) provide patientswith the special comfort feature C-Flex. When enabled, C-Flex enhances patient comfort by providing pressure

CAUTION

U.S. federal law restricts this device to sale by or on the order of a physician.

NOTE

There are two REMstar Auto M Series devices - REMstar Auto M Series with C-Flex and REMstar Auto M Series with A-Flex. Unless specified, references to theREMstar Auto M Series throughout this Service and Technical Information packageinclude both the C-Flex and A-Flex models.

INTRODUCTION - PAGE 11031209, REV. 04


relief during the expiratory phase of breathing. C-Flex levels of 1, 2, or 3 progressively reflect increasedpressure relief.

A-FLEX FEATURE

A-Flex is a special comfort feature that is only active if Auto-CPAP therapy is enabled. When A-Flex is enabled,patient comfort is enhanced by a small amount of pressure relief during the latter stages of inspiration andduring active exhalation (the beginning part of exhalation). A-Flex levels of 1, 2, or 3 progressively reflectincreased pressure relief.

BI-LEVEL DEVICES

The BiPAP Plus M Series and BiPAP Auto M Series bi-level devices sense the patient’s breathing effort bymonitoring airflow in the patient circuit and adjust the output pressure to assist in inhalation and exhalation.This assistance is provided by the administration of two levels of positive pressure. During exhalation, pressureis variably positive or near ambient. During inspiration, pressure is variably positive and always equal to orhigher than the expiratory level. The BiPAP Plus M Series can operate in either Bi-level mode or Bi-level withBi-Flex®. The BiPAP Auto M Series can also operate in Auto Bi-Level or Auto Bi-Level with Bi-Flex.

Bi-Flex "softens" the airflow in inhalation and exhalation, making the patient’s breathing more comfortable. Inthe Bi-Flex mode, the amount of pressure relief at the end of inhalation and at the beginning of exhalation isestablished. Patient-adjustable settings of 1, 2, or 3 provide progressively increased pressure relief.

NOTE

The REMstar M Series is not equipped with C-Flex. The REMstar Pro M Series,REMstar Plus M Series, and REMstar Auto M Series are equipped with C-Flex.

NOTE

• A-Flex must be enabled by the Home Care provider.

• A-Flex transitions from no A-Flex at 4.0 cm H2O to full A-Flex at 6 cm H2O. A-Flex is top limited at 20.0 cm H2O pressure.

THEORY OF OPERATION

INTRODUCTIONThis chapter describes the operation of the M Series Sensor Board Printed Circuit Assembly (PCA). Operationof the various circuits on the board are explained. Also included are the specifications for the inputs andoutputs of the board.

REAL-TIME CLOCKThe Real-time Clock on the Sensor Board is the source of time for the M Series sleep therapy devices. It takesadvantage of Timer 1 on the PIC16LF818 and its ability to run while the rest of the processor is in sleep mode.

CRYSTAL

The Real-time Clock uses a 32.768kHz crystal attached to the Timer 1 oscillator ports on the PIC. This is acommon watch crystal frequency because 2^15 cycles equals one second. A crystal specified with ±20ppmaccuracy rating and 12.5pf load capacitance is used. Based on experimental testing, capacitors C4 and C5have been set at 15pf to get accurate timekeeping. Reducing those capacitors will make the clock run faster,while increasing those capacitors will make the clock run slower.

BATTERY

When the +5V system voltage is present, the PIC runs in an active state from that supply. When the +5Vsystem voltage is not present, the PIC software shuts down most of it functions and enters sleep mode. TheReal-time Clock on Timer 1 will continue to run off of a 3V lithium coin style battery. CR1 is a dual packagecommon cathode Schottky diode used for steering between the supply voltage, when present, and the battery.Reverse leakage of the diode must be less than 1% of the battery capacity for the expected lifetime becausereverse charging currents may reduce the life of the battery. (1% * 235 mAh) / (8760 h/year * 5 years) = 53.7nA. R21 is required by UL to limit the reverse charging current to prevent a safety hazard in the event that thediode fails. Current must be limited to 25mA.

J2 is a two pin header that allows the battery to be soldered to the circuit board but remain disconnected fromthe circuit before the PIC is programmed and properly reset. Before a proper reset, the current draw of the PICis large and will drain the battery prematurely. A shunt is placed on the header to connect the battery after ithas been programmed and is verified to be operating correctly. The shunt is installed for the operating life ofthe board.

THEORY OF OPERATION - PAGE 11031212, REV. 02


FLOW SENSORThe flow sensor is used in a bypass configuration where a flow element in the main air path creates a smallpressure drop so that a portion of the airflow will travel through the sensor.

HEATER

The flow sensor operates by airflow transferring heat between heated resistors and sense resistors. The senseresistors are the bottom half of a resistive bridge. The bridge output voltage is then an indicator of the massairflow through the sensor.

The heater resistors are kept at about 160 °C above ambient temperature by the heater control circuit. Thecircuit used includes the addition of Q2, which is used to increase the drive capability of the op amp.

AUTO NULL

Offset error is achieved by applying an appropriate voltage into the reference input of the instrumentationamplifier U2 so that at zero flow, the voltage being read at the A/D of the PIC is at mid-scale, nominally 2.5V(half of the 5V supply).

The PIC uses a PWM output to create a square wave of approximately 4kHz. The square wave is filtered withan RC network and buffered with gate B of op amp U1 to create the DC voltage for the reference. A levelshifting OR gate is used to buffer the square wave. This bases the pulse width modulation (PWM) voltagedirectly on the +5V supply instead of the Vdd supply on the PIC, which is a diode drop below +5V supply. Thevoltage drop across the diode will vary with temperature, and could cause a shift in the offset voltage if thePWM were not buffered.

When the blower is not running and the signal from the flow sensor is stable, the PIC will adjust the duty cycleof the PWM so that the output of the flow sensor amplifier is at mid-scale of the PIC A/D converter input. ThePWM value is maintained at a fixed value once the blower is started or a patient begins breathing into thedevice.

AMPLIFIER

The bridge output of the flow sensor goes into an INA321 instrumentation amplifier. A nominal gain ofapproximately 24.7 provides the most resolution in the flow signal, while allowing enough range to measure atleast +/- 128 LPM of flow, over the entire range of flow sensor variability. The reference input of this amplifierprovides a simple means for adding the auto null offset value directly to the amplified flow signal.

CALIBRATION

The Sensor Board must be calibrated in order to provide accurate flow measurements. The calibrationprocedure involves applying known flow rates to the sensor board and reading out the raw A/D counts. Acalibration table is calculated and then the data is populated into a lookup table. The table is then programmedinto the Sensor Board PIC. During regular use, the PIC will take the raw A/D counts measured from the flowsensor and amplifier, perform a linear interpolation between points in the lookup table, and calculate the actualflow.

PRESSURE SENSOR FOR PRESSURE CONTROLThe custom version pressure sensor is a gauge style sensor which is amplified, calibrated, and temperaturecompensated.

1031212, REV. 02PAGE 2 - THEORY OF OPERATION


SENSOR PLUS ASICThe sensor provides an amplified, calibrated, and temperature compensated voltage output by combining aresistive bridge style silicon sensing element and an ASIC. The ASIC consists of a 12 bit analog/digital (A/D)converter, a 16 bit microcontroller, and an 11 bit D/A converter. The ASIC also senses chip temperature so thatit can compensate the pressure value for temperature effects.

The ASIC has a digital interface available so that the pressure values can be read directly. This would eliminateany potential errors from the D/A of the ASIC and the A/D of the PIC.

SENSOR CALIBRATION

The pressure sensor calibrated prior to installation. For each sensor, three different pressures are measured attwo different temperatures. The results are used to calculate seven coefficients for the correction calculation.The sensor is calibrated to output 0.5V at -5 hPa (-5 cm H2O) and 4.5V at 40 hPa (40 cm H2O) when thesupply voltage is 5.0 V. The ASIC has a sampling rate of approximately 10ms and the analog output has aresolution of approximately 3 mV.

AUTO NULL

The analog voltage output of the sensor goes directly into an A/D channel of the PIC. When the blower is notrunning and the signal from the flow sensor is stable, the PIC performs a mathematical auto null for thepressure sensor. It assumes there is zero pressure, so it will record the raw A/D value as the zero pressurepoint. When the blower is on, the PIC will subtract the offset value that it has stored.

BOARD CALIBRATION

After the sensor is installed on the Sensor Board, there is a board level calibration. The calibration procedureinvolves applying known pressures to the sensor board and reading out the raw A/D counts. This data ispopulated into a lookup table, and then programmed into the Sensor Board PIC. During regular use, the PICwill take the raw A/D counts, perform a linear interpolation between points in the lookup table, and calculate theactual pressure. This calibration will compensate for any changes that have occurred to the sensor during theassembly process or any mechanical strain on the sensor from mounting it on the circuit board.

PRESSURE SENSOR FOR SNORE DETECTIONThe compensated output is sampled too slowly and has too little resolution to be used to detect snores.Therefore, access to the actual resistive bridge is provided by the sensor’s vendor.

AMPLIFIER AND DC REMOVAL

The bridge output of the pressure sensor goes into U5, an INA321 instrumentation amplifier. A nominal gain ofapproximately 24.7 will provide the largest signal level while allowing enough range to remove the DCcomponent of the signal across the expected variations in sensor sensitivity. The reference input of thisamplifier provides a simple means for removing the DC component of the signal, and setting the DC level toapproximately 1.5V. The A/D input on the Therapy Board is referenced to 3V, so the DC level of the SnoreSignal is half-scale.

Op amp U3, gate B provides the DC removal. It adjusts its output, which goes into the reference input of U5 sothat the output of U5 is equal to the approximate 1.5V reference created by R11 and R12. AC signals can passthrough C15 so that they will not be removed. The cutoff frequency for R10 and C15 is provided by the formula1/(2πRC) or 15.9Hz.



AMPLIFIER AND LPFThe output of U5 is then amplified again to create a large enough signal for detecting snores. Op amp U3, gateA along with R13 and R27 provide a gain of 49.9 while maintaining the approximate 1.5VDC offset. C16 inparallel with R13 provides a low pass filter to remove higher frequencies. The cutoff frequency for R13 and C16is provided by the formula 1/(2πRC) or 319Hz.

COMMUNICATIONS CHANNELThe PIC communicates with the device therapy board by way of an SPI bus. There are also two reset signalsavailable.

SPI BUS

The PIC has a built in SPI port for communications. This bus requires 5V signaling levels because the PIC runsoff of 5V when the unit is powered up. The SPI Bus is the means for transferring sensor data, clock data,calibration data, and other information to and from the Therapy PCA.

RESETS

There are two reset lines coming into the Sensor Board. One called Therapy Reset is used as a piece ofinformation by the PIC software for the decision when to transition from sleep mode to active mode. The PIClooks for any edge on this signal as an indication to wake up. The second line is called Sensor Reset. It can beused by the Therapy Processor to reset the Sensor Processor as a final action when the Therapy Processorcan not communicate with the Sensor Processor. This signal is active high. Transistor Q1 is used to providean open collector, active low reset signal to the ~MCLR pin on the PIC.

OTHER I/OThe sensor board requires two voltage supplies and ground. The amplified snore signal is output in analogform to the therapy board.

POWER SUPPLIES

The Sensor Board circuitry requires a +5V supply and a +8V supply. The +8V is required for the flow sensorheater circuit. The rest of the board runs on +5V, except for the real-time clock when +5V is not present. To bewithin the specified limits of the pressure sensor, the +5V supply must be between 4.75 and 5.25V. The +8Vsupply must be greater than 7.3V to supply enough voltage to the flow sensor heater under worst caseconditions. It should be less than 8.5V, so that the supply divided down by R19 and R30 will not exceed Vdd ofthe PIC.

The sensor board creates the +5V supply from the +8V supply with a linear regulator. This will ensure that, foreach sensor board, the same +5V supply will be used at time of calibration and during normal operation of thedevice.

ANALOG SNORE OUTPUT

The Sensor Processor does not have the processing capacity to run snore detection software, so the snoreoutput is provided as an analog signal. The amplified AC signal rides on an approximately 1.5V DC level. Thenominal signal level is 568mV per hPa (cm H2O) of pressure.



DEBUG PORT

A connector on the board allows the connection of a Microchip MPLAB ICD 2 In-Circuit Debugger that can beused for programming and debugging the PIC. This connector will not be used during normal operation of thedevice.

PRESSURELESS SENSOR BOARDSome M Series units do not need a pressure sensor. Table 4 includes the components not installed on thePressureless Sensor Board:

TABLE 4: COMPONENTS NOT INSTALLED ON PRESSURELESS SENSOR BOARD

A 100Ω resistor may be installed at R33 on the pressureless sensor board as a “hardware” indicator to thetherapy board that the pressure sensor is not installed. On the therapy board, a 100kΩresistor pulls this signaltoward the midpoint (nominally 1.5 V) of Vref (3.0 V). The 100Ω resistor on the sensor board will pull this signaltoward ground.

ERROR CODES

INTRODUCTIONThis section provides a list of the error codes for the M Series CPAP devices. Error codes are stored in thedevice’s memory. To view and clear the device’s error log, refer to the Testing section of this Service &Technical Information package.

The error codes listed in this section are shared by the following M Series products:• REMstar M Series CPAP Device

• REMstar Pro M Series CPAP Device

• REMstar Plus M Series CPAP Device

• REMstar Auto M Series CPAP Device (C-Flex and A-Flex models)

• BiPAP Pus M Series Bi-level Device

• BiPAP Auto M Series Bi-level Device

• M Series Integrated Heated Humidifier

ERROR TYPESThe four types of errors are described as follows:

NOTE

To Read and Clear Error Logs, you must log onto http://my.respironics.com and download the Utility Tools Software.

NOTE

Please note that not all error codes apply to all devices. Forexample, the REMstar M Series device is not equipped with aSensor PCA; therefore, error codes that indicate a failedSensor PCA are not used on the device.

ERROR TYPE DESCRIPTION

STOP “Service Required” is reported as soon as the condition is detected.

REBOOT The device will restart for no more than four occurrences of these Error Types within a 24hour period, otherwise, the device displays “Service Required”.

CONTINUE &LOG_ONLY

These Error Types do not interrupt the performance of the device and are only recordedin the log.

PAGE 1 - ERROR CODES1031255, REV. 04


ERROR CODE CHART

NOTE

Repair suggestions are included on page 9 of this section forError Codes marked with an asterisk (*) in the following table.

SPECIAL NOTE

When examining the Error log, pay close attention to the type of error code that is logged and thenumber of times each error is logged. This will help you to determine the correct action to takewhen servicing the device. When five REBOOT level events occur within a twenty-four hourperiod, the device will enter “Service Required” Mode. If as many as four REBOOT level errorsoccur in a single 24 hour period, the device is considered to be within operating specifications andno action is necessary.

A REBOOT error has several potential root causes. To better determine the actual cause, the errorlog should be examined to determine if any other REBOOT level errors occurred during the sametime period. These errors may offer a better diagnosis of the actual problem.

M SERIES SLEEP THERAPY DEVICE REPAIR & REPLACEMENT

OVERVIEWThis section provides procedures for removing and replacing M Series CPAP and Bi-level device componentsand identifies the replacement part (RP) kits available for the devices.

“VER2” M SERIES DEVICESIn May of 2007, Respironics implemented a design change to the following M Series parts:

• Therapy PCA

• Sensor PCA

• Accessory Interface PCA

• Sensor PCA Cable

• Accessory Interface PCA Cable

These parts are not compatible with the previously designed parts. M series devices manufactured with theseparts can be identified by a “VER2” marking on the Serial Number/Model Number Label located on the bottomof the device. Refer to the following illustration.

FIGURE A: SERIAL NUMBER/MODEL NUMBER LABEL

IMPORTANT REMINDER

There are two REMstar Auto M Series devices - REMstar Auto M Series with C-Flex and REMstarAuto M Series with A-Flex. Unless specified, references to the REMstar Auto M Series throughoutthis Service and Technical Information package include both the C-Flex and A-Flex models.

NOTE

The M Series Sleep Therapy device must be run-in for two hours and final tested after any repair.Refer to the Testing & Calibration section of this M Series Service and Technical Information packagefor instructions on testing M Series devices.

M Series devices that contain the re-designed parts can be identified by “VER2” on the Serial Number/Model

PRESSURE VERIFICATION

The Pressure Verification test may be used to determine that the device is functioning properly. Thisverification should be performed for preventive maintenance at periodic intervals commensurate with hospitalor home care provider guidelines, between rentals, during normal patient usage (as routine maintenance), orwhenever a device is returned for service.

REQUIRED EQUIPMENT FOR THE PRESSURE VERIFICATION TEST

• Pressure Measurement Kit (RI p/n 1026062), which includes the following:

a. Whisper Swivel® II (RI p/n 332113)b. O2 Enrichment Attachment (RI p/n 312710)

c. End cap or similar device for occluding the O2 Enrichment Attachment

• 0.25” Test Adapter (RI p/n 332353)

• Pressure tubing: PVC Tubing, 1/8” (3.75mm) I.D. x 1/4” (6.35mm) O.D., 6-12” (15.24 to 30.48cm) long (RI p/n 304018)

• Respironics Digital Manometer (RI p/n 302227) or equivalent with the following minimum specifica-tions:• 0 – 70 hPa (0-70 cm H2O)

• ±0.3 hPa (±0.3 cm H2O) accuracy

• ±0.1 hPa (±0.1 cm H2O) resolution

• M Series Tubing and Swivel kit (RI p/n 1029532)

• Pollen (Inlet) Filter (1035443)

• M Series Power Supply

PRESSURE VERIFICATION PROCEDURE

Perform the following:1. Install a gray foam Pollen (Inlet) Filter into the device.2. Connect the 0.25” Test Adapter to the outlet of the device and run in the device for at least two

hours.

NOTE

The Pressure Verification test may be used to determine that M Seriesdevices are functioning properly. The manual test software described laterin this section can not be used with the REMstar M Series device (with thenon-removable Blank Accessory Module), and therefore, the followingPressure Verification test acts as the final test for the REMstar M Seriesmodel device.

NOTE

M Series Sleep Therapy devices may display either hPa or cm H2O.1 hPa = 1 cm H2O

1031257, REV. 04PAGE 2 - TESTING


3. With the device unplugged, connect the system as shown in Figure B.

FIGURE B: PRESSURE VERIFICATION SETUP

4. Turn the manometer on and adjust it to read zero.5. Plug in the device while simultaneously holding down the left arrow and right arrow buttons to

enter Provider Mode.6. Set the device to 4 hPa (4 cm H2O).

NOTE

If the M Series Sleep Therapy device was returned for service with a Humidifier,Respironics recommends that the Pressure Verification procedure be performedboth with and without the Humidifier.

Then dock the device onto the Humidifier and perform the pressure verification

test again.

If a Humidifier was returned for service with the device, perform the pressure verification

test without the Humidifier first.

Whisper Swivel II



7. Press the M Series Sleep Therapy device’s Start/Stop button to turn the blower on.8. Verify the manometer reads 4 hPa (4 cm H2O) ±1 hPa (±1 cm H2O). If the pressure setting does

not match the measured value, adjust the device’s Fine Pressure setting (if available) as neces-sary. Refer to the device’s Provider Manual for additional information on menu options.

9. Set the device to the maximum output pressure setting as follows:• 20 hPa (20 cm H2O) for CPAP devices

• 25 hPa (25 cm H2O) for Bi-level devices

10. Verify the manometer reads 20 hPa (20 cm H2O) ±2 hPa (±2 cm H2O) for CPAP devices or 25 hPa (25 cm H2O) ±2.5 hPa (±2.5 cm H2O) for Bi-level devices. If the pressure setting does not match the measured value, adjust the device’s Fine Pressure setting (if available) as necessary. Refer to the device’s Provider Manual for additional information on menu options.

11. If the M Series Sleep Therapy device was returned for service with a Heated Humidifier, perform the following:a. Dock the M Series device onto the M Series Heated Humidifier.b. Connect the Whisper Swivel, 0.25” Test Adapter, tubing, manometer, etc., as shown in Figure

B.c. Perform the preceding steps 3 through 10.

d. Turn the Humidifier to any setting other than zero while the Sleep Therapy device is on and verify the LED on the Humidifier dial is on.

5. Record all information on the Pressure Verification Data Sheet(s) provided on page 26 and page 27.

NOTE

The Fine Pressure setting is not available onall M Series devices.

NOTE

Output pressures may vary at local altitude and barometricpressure. Because of these factors, devices may slightly varyin output pressure over the range of the altitude settings.

IMPORTANT NOTE

A slight drop in output pressure is expected when the M Seriesdevice is docked onto a Humidifier. The tolerance for the outputpressure is ±0.3 hPa (±0.3 cm H2O) of the measured values takenfrom the device without the Humidifier. Therefore, when the deviceis set to 20 hPa (20 cm H2O), the minimum acceptable outputpressure value is 17.7 hPa (17.7 cm H2O).
