D Welch Allyn Atlas Monitor ix x Welch Allyn Atlas Monitor Service Manual 6200-43E Rev. D General Information Section 1 About the Atlas Monitor The Atlas Monitor combines in one unit all the necessary measurements for patients under anesthesia, for surgical recovery, or bed side monitoring. See Section 1, page 5 for a complete listing of product models and options. According to the standards of care for Nurse Anesthetists and Anesthesiologists, all patients receiving conscious sedation are to be continuously monitored throughout the procedure and recovery phase by ECG, SpO2, and NIBP. CO2 monitoring is a requirement during gas anesthesia (when patient is ventilated). The Atlas combines a CRT to display ECG, CO2, SpO2, and respiration waveforms. It utilizes LEDs for the other numeric values to maximize visibility and viewing angle. Although not designed to be a transport product, the monitor has an integral handle and it is small and light enough at 13 lbs. to be easily moved. A battery was added to enable the monitor to be used if there is a power outage or to be unplugged momentarily when moved with the patient from the surgery room to the recovery room. The battery was not designed to make the Atlas into a transport monitor. The Atlas monitor should be plugged into AC as much as possible to give you the maximum battery backup time when there is a power outage. It will maintain unit operation for up to an hour when power is interrupted if the battery is fully charged. WARNING: Discharging the battery frequently will shorten the battery life and will shorten the battery backup time. IMPORTANT: For a complete description on the function and use of the Atlas, as well as user safety warnings, cautions, and warranty information, read and understand the Atlas Operator’s Manual. See the Table 1-1 below for correct Operator’s Manual part #. Table 1-1. Operator manual part numbers. Service Manual 6200-43E Rev.

Example and Explanation of an Atlas Service Screen Line A Indicates that the Atlas is a model 220 and that the Atlas has a printer. If the Atlas did not have a printer then the text “with printer” would be absent. The date field following indicates the date the Atlas was last calibrated. Line B starts with a numeric sequence. The first three digits are the model number of the Atlas. The next five numbers are the Atlas serial number. The next sequence,alphanumeric, indicates what software version is currently loaded into the Atlas. The third sequence, alphanumeric, indicates what version boot software is currently loaded into the Atlas. Line C starts with the SpO2 OEM board used in the Atlas. There are two SpO2 OEM boards used in the Atlas. One is Nellcor and the other is Nonin. The next sequence indicates the model of the SpO2 board. The next sequence, that starts with a letter “V”, is the version software used with the current SpO2 board. The date following the SpO2 software is the date the OEM loaded the software into the SpO2 board. SpO2 OEM software can not be upgraded. If the most current software is needed, you will need to replace the SpO2 board. Line D is the CO2 information if your Atlas has CO2 installed. Only models 623 have CO2 installed. If your Atlas does not have CO2 installed then line D will be absent. If your Atlas has CO2 installed then line D will start with CO2 followed by a numeric number. That numeric value is the software loaded into the CO2 board. The next alphanumeric sequence, starting with a “V”, is the version of that software. The next numeric sequence starting with a “#” is the serial number of the CO2 board. The next sequence, a date, is the date the CO2 was last calibrated. The last sequence, a date, is the date the CO2 was reset. CO2 OEM software can not be upgraded. If the current software is needed, you will have to replace the CO2 board. Service Manual 6200-43E Rev.

The model 621 can only be powered from external AC. The following supplies are generated on the Atlas Main Board: +12V DC CRT, input to isolated power supply, misc. analog circuits. 6V DC NIBP Pump and Valve, input to 5V and 3V regulators (5.7V nom). +5V DC Front panel LED’s, misc. logic. +3.3V DC CPU board.

This voltage is diode OR’d (D304) with the lithium backup battery to provide power to the real time clock on the CPU board. The On/Off circuitry is controlled by the micro controller U305. This controller performs the following functions: Service Manual 6200-43E Rev. D Welch Allyn Atlas Monitor 77 Appendix A Theory of Operation 1. Monitors the status of the front panel ON-OFF key. If the unit is off and the ON-OFF key is pressed, the controller will drive U10-6 high, which will enable power to the remainder of the instrument. 2. At power up, the micro controller will drive the beeper for about 1 second. 3. At power up, the micro controller will reset Shift Register U2. This will cause the following: a. The front panel LED's are blanked. b. The NIBP pump drive is placed in the off state. 4. When the unit is ON the micro controller will communicate with the system CPU. When the front panel ON-OFF key is pressed, the CPU will store away current operating conditions, then issues a command to the micro controller to shut instrument power off. U10-6 is driven low which will remove power from the remainder of the instrument. The instrument is powered on as follows: U305-6 is driven high, which turns transistor Q302 on (output low) Q301 (P-channel MOSFET) ON when the gate is pulled low, then +12V active. Q306 is turned off, allowing the 5.7V buck converter to power on. As 5.7V becomes active, the 5V and 3.3V supplies also become active.

On/Off Control Circuits. Buck Converter A buck converter is used to generate 6V from the 12VDC output of the offline switcher. The UC3843A (U301), normally a current mode controller, is configured for voltage mode feedback. The UC3843A has an under-voltage lockout for Vcc<8.5V. The controller operates such that with Vcc less than 8.5V, the reference out is 0V, and will be at 5V with Vcc>8.5V. 78 Welch Allyn Atlas Monitor Service Manual 6200-43E Rev. D Theory of Operation Appendix A Then, the reference out (pin 14) can be used as an AC-ON detection signal. The switching transistor for the buck converter is a P-Channel MOSFET (Q305). The output drive of the controller is the wrong polarity for driving a P-Channel MOSFET in a step down mode. Therefore, transistor Q303 is added to invert the PWM out signal. Fast turn-on of Q305 is provided when Q303 is low, fast turn-off is though Q304 (configured as an emitter follower). The PWM controller includes an internal 2.5V reference. Voltage regulation is controlled with sampling resistor R304 and R305 such that Vout = 2.5V*(1+R304/R305) = 5.68V. At power down pin U301-1 (comp pin) is pulled low. This will cause U301-10 to go low, which turns Q305 off and disables power to +6V.

If the unit is off and the ON-OFF key is pressed, the controller will drive U10-6 high, which will enable power to the remainder of the instrument. 2. At power up, the micro controller will drive the beeper for about 1 second. 3. At power up, the micro controller will reset Shift Register U2. This will cause the following: a. The front panel LED's are blanked. b. The NIBP pump drive is placed in the off state. 4. When the unit is powered on the micro controller will communicate with the system CPU. When the front panel ON-OFF key is pressed, the CPU will store away present operating conditions, then issues a command to the micro controller to shut instrument power off.

D Welch Allyn Atlas Monitor 81 Appendix A Theory of Operation 18V boost converter and FET ON/OFF switch The PWM controller, U301, is configured as an 18V boost-converter. An N-Channel MOSFET transistor, Q303, is used to switch power to the 12V regulator. As Q303 is configured as a high side switch, it is necessary to develop a gate voltage of proper magnitude to turn Q303 on. Then, to enable power to the 12V regulator, the following takes place: 1.

The input to the 12V converter is either battery or 12V from the AC/DC converter. The circuit is configured as a boost PWM using current mode feedback. The PWM controller is a UC3843A. The controller includes an internal 2.5V, 2% reference, and an external 5V, 2% reference. Nominal output voltage for the boost converter is Vout = [2.5V*(1 + 173.8K/4.64K)] = 12.1V. The UC3843A requires 8.5V minimum to power on. The maximum voltage allowed on the switching transistor, Q305, is 15V. To meet both these requirements, the UC3843A is powered from 12.9V (+18V – 5.1V zener diode D303) When operating from battery, the converter will run at duty cycles over 50%, which requires slope compensation for a current mode controller. Slope compensation is achieved by summing in part of the oscillator signal (pin 4) with the current sense line. The PWM controller is current limited on a cycle to cycle basis by monitoring the voltage on the Isense line, U302-5. Current limit is activated when the voltage at the sense line reaches 1V. The nominal DC voltage at Isense is about 0.5V when operating from battery only, and 0.7V when operating from AC. Then, current limit is set to 5Amps when Atlas in operating on battery and 3Amps when operating on AC.

Boost converter. Service Manual 6200-43E Rev. D Welch Allyn Atlas Monitor 83 Appendix A Theory of Operation Battery Charger The battery charger is a PWM buck converter. The input to the battery charger is 12VDC from the offline switcher. The UC3843A, normally a current mode controller, is configured for voltage mode feedback. The UC3843A has an under-voltage lockout for Vcc<8.5V. The controller operates such that with Vcc less than 8.5V, the reference out is 0V, and will be at 5V with Vcc>8.5V. Then, the reference out (pin 14) can be used as an AC-ON detect signal. The switching transistor for the buck converter is a P-Channel MOSFET (Q308). The output drive of the controller is the wrong polarity for driving a P-Channel MOSFET in a step down mode. Therefore, transistor Q306 is added to invert the PWM out signal. Fast turn-on of Q308 is provided when Q306 is low, fast turn-off is though Q307 (configured as an emitter follower). The battery charger is a current limited - temperature compensated charger. Current limit is set to 1.5Amps. Current through the 0.1Ohm sense resistor R327 is measured with Diff-Amp U305B. When the charger current is at 1.5Amps, feedback is controlled by Op-Amp U304A. When the current drops below 1.5Amps, the output of U304A goes low, reverse biasing Diode D308, and feedback will be controlled by Op-amp U304B. Battery charge voltage is temperature compensated using Thermistor RT301, a 10K negative temperature coefficient resistor. Voltage over temperature follows the following charge profile: Table A-1. Temperature coefficient. Temperature 0C 10C 25C 40C 50C Voltage 7.05V 7.0V 6.85V 6.7V 6.65V Thermistor 26.9K 20.7K 10K 5.17K 3.45K For optimum battery life, the float voltage (25C, full charge) should be set to 6.85V +/- 50mV (6.85V +/- 0.7%). To accomplish this tight tolerance, charge voltage at room temperature will be adjusted with potentiometer R328. Nominal charge voltage at room temperature is: Vcharge = 5V * (1 + RA/RB) where, 5V is the reference in U303. RA is the series/parallel combination of R335, R336, and RT301 (nominal 3.465K @ 25C). RB is the series combination of R337and R338 (nominal 936 Ohms) It is necessary to minimize current out of the battery when the unit is off. To reduce off current, transistor Q309 disconnects the battery from the battery sense resistors when AC in off. In addition, diode D307 is added to prevent current from flowing from the battery into the battery current sense circuit, and to the output of the AC/DC converter. 84 Welch Allyn Atlas Monitor Service Manual 6200-43E Rev.

A 5V reference from U302 PWM IC) is used as the control voltage for the regulator. The output of the 5V regulator is turned off when the unit is turned off. When the 18V-boost circuit is shut down, power is removed to U302, then the U302 reference is driven to 0V. Setting the reference to 0V will cause op amp U305 to turn the series pass transistor Q312 off. When operating from AC, transistor Q310 is turned on, which will turn transistor Q311 off. Power to the 5V regulator is then provided through Diode D310 from the output of the battery charger circuit. Note that this voltage tap is before the current sense resistor, then load current on +5V does not affect the battery charger current limit circuit. When AC is removed, the AC-On signal goes low, and Q310 turns off. The gate of Q311 is then pulled up to 11.4V (12V – Vdiode). Transistor Q311 then turns on, and the 5V regulator is powered from the battery. 3.3VDC is derived using a three terminal regulator. The output of the 5V regulator is used to power the 3.3V regulator. The 3.3V regulator does not have an independent shutdown, but powers down as the 5V regulator shuts down.

Linear regulator. A/D – grounded circuits The A/D converter is designed by building a pulse width modulator (PWM) and a timer circuit. The PWM runs at a 1.2KHz rate, synchronized by the A/D sync signal (NIBP-ADCClock). A/D sync is low for 52.1uSec, high for 781.25uSec. Component values are selected such that the integrator will ramp down 4.7V, and ramp up 7.83V. The voltage at the integrator output (U601-1) is limited to about 5V [5V*(73.2/83.2) + Vdiode)]. Then, the integrator starts at 5V and ramps linearly down to 0.3V. The analog input voltage to be digitized and the integrator output are the inputs to comparator U210. The output of the comparator is low at the start of an A/D cycle, and switches high as the integrator ramp drops below the input voltage being digitized (see the timing diagram below). A/D conversion is accomplished by measuring the width of the PWM output signal. The A/D timer runs at 25.175MHz, then the A/D resolution is about 21000 counts (over 14 bits). Note that since the output of the comparator is low at the start of the A/D cycle, a resistor divider is formed at the comparator input. This divider reduces the Analog-In signal by 0.75% [464K/(464K+3.48K)].

NIBP Circuits Overview - Safety: Two pressure transducers are used, a primary and safety transducer. The primary is used to make all BP measurements. Hardware circuits monitor the output of the primary transducer, looking for overpressure faults. In addition, Software monitors the digitized outputs of the primary transducer, and detects overpressure faults. The following overpressure faults are detected in software (monitored once per second): >=10mmHg pressure for 295 seconds >=15mmHg pressure for 175 seconds >295mmHg pressure for 0.5 seconds. Service Manual 6200-43E Rev. D Welch Allyn Atlas Monitor 87 Appendix A Theory of Operation Software detected overpressure faults are considered application faults. The user is warned of a fault with an audible alarm and a ‘Check blood pressure cuff’ message on the CRT display. NIBP is not disabled for this type of fault. In the event of a fault, the drive signals to the NIBP pump and valve are opened. Two hardware faults are detected, pressure over 330mmHg (nominal trip point 314mmHg, and pressure over 15mmHg for three minutes (13.3mmHg nominal trip point). These faults are considered more serious (since software should have detected and corrected this condition). The user is notified with a ‘BP SYSTEM FAULT’ message, and NIBP is disabled. A redundant safety transistor is opened to ensure the NIBP pump is off and the valve is open. The primary and safety transducer outputs are continuously digitized. The outputs of the transducers are checked vs. each other, and if they disagree, an ‘NIBP Fault Message’ is declared and the NIBP system is disabled. The outputs of the transducers are linearly proportional to the supply voltage (supply current for the safety transducer). The transducers use unique reference voltages to ensure that a fault in one reference will not cause an equivalent gain error in both transducers. The A/D also has redundant checks. Two reference voltages (derived from the primary transducer reference supply) are measured, and the A/D gain and zero is checked. In addition, a unique reference is digitized, and compared vs. expected results. An error in any of these A/D measurements will again cause an ‘NIBP Fault Message’, and the NIBP system will be disabled. Primary Transducer - Amplifier: The primary pressure transducer is a fully calibrated and compensated transducer with built in voltage amplification. The output of the transducer is proportional to the supply voltage. With a 5V supply, the output of the transducer is: 0mmHg = 0.5V. 300mmHg = 4V. Op amp U204A is used to level shift the output of the transducer such that the nominal voltage for 0mmHg is set to 0.75V. The CPU monitors the digitized zero pressure voltage, and any offset is corrected. This correction comes from the summation of an error correction signal through op amp U204B. The CPU will output a pulse width modulated signal at 76.8KHz. This signal is RC filtered to provide ad DC voltage at U204-5. This signal can adjust the offset seen at the A/D converter by +/-20mmHg. 88 Welch Allyn Atlas Monitor Service Manual 6200-43E Rev.

Primary transducer amplifier. Safety Transducer - Amplifier The safety transducer is compensated for temperature drift, but gain and zero are not calibrated. The safety transducer does not include built in voltage amplification. The safety transducer output is a differential voltage, proportional to the supply current through the device. The initial accuracy of the safety transducer is very loose, in the order of +/-50%. However, the drift over time and temperature is very good. Then, it is necessary to calibrate the output of the safety transducer. This is done my measuring a know pressure, measuring the output of the safety transducer, and storing calibration constants in NVRAM. A two-point calibration procedure is used. Calibration is done at the factory, and can be recalibrated in the field if necessary. Current Source: Op amp U205A is configured as a current source for the Pressure Transducer, with the current through the transducer set to 1.5mA. Nominal gain for the transducer is 300mmHg = 75mV. Differential Amplifier and Offset Centering: The output of the safety transducer is a differential voltage, with a nominal gain of 0.25mV/ mmHg, and a zero pressure offset voltage of +/-25mV. The A/D converter has an input voltage range of 0.5V to 5V. It is necessary to both add both signal gain and offset centering to the transducer output before digitalization. Op amp U206A/B is configured as a differential amplifier, with a voltage gain of 22.5. The output of the differential amplifier is offset by 1.2V (U205B). Service Manual 6200-43E Rev.

Safety transducer amplifier. Hardware Overpressure: The output of the primary transducer is monitored for two overpressure conditions; pressures in excess of 13.3mmHg (nominal) and 314mmHg (nominal) are detected. These error conditions are transmitted to the gate array on the CPU board, and if the error conditions are present for a long enough time period, a fault message is displayed, and NIBP is disabled (see above for safety performance operation). The output of the Primary Transducer drives the two comparators U203A/B. The comparison voltage is derived through a resistor divider chain from a 5V regulator (U201). This regulator is the supply voltage for the primary transducer, and sense the primary output is proportional to the supply voltage, tolerance errors in the regulator are not critical. 90 Welch Allyn Atlas Monitor Service Manual 6200-43E Rev.

Once a fault is detected, Q202 will remain open until power is cycled. Under normal operation, dual transistor Q203 is used to switch the pump on and close the valve.

The CRT Deflection board performs the following functions: 1. Vertical Deflection. 2. Horizontal Deflection. 3. CRT Grid Voltages. 4. Video Amplifier. CRT Deflection is magnetic, vertical and horizontal deflection is controlled by regulating current through the vertical and horizontal coils of the CRT Yoke. The Deflection board is designed to the following specifications: Resolution: VGA (640X480) Dot Clock: 39.7nSec (1/25.175Mhz) Display Size: 100mm (Horizontal) X 68mm (Vertical) Vertical: Scan Rate: 60Hz Reset Time: 750uSec Blanking Time:1.2mSec Horizontal: Scan Rate: 31.5Khz Reset Time: 5uSec Blanking Time: 5.7uSec Vertical Amplifier: Ramp Generator: Vertical Sync Ramp Generator R1 1K U1.3 +5V +12V R2 7.50K C3 .047uF 750uSec 8 16.7mSec R3 23.7K U4A R52 1.96K 2 3 2 U4.2 + 1 - Ramp U1A TLC272 Vertical Sync 4 1 Vsync 74HCT04 R43 5.0V C1 .1uF 5.11K 3.95Vpp U1.2 d6.c 2 D6 1N4148 1 2 1 D1 1N4148 750uSec 16.7mSec Figure A-16.

D Theory of Operation Appendix A is: V = (I*T)/C. The integrator is designed so that it ramps up 6.97V in 750uS and ramps down 3.95V in 15.9mS. Diode D1 clips the output voltage at about 5.0V (U1-pin3 + Vdiode). Then the ramp resets at 5.0V each cycle, and integrates down 3.95V.

Vertical amplifier circuit Vertical Amplifier: The Vertical amplifier will generate a linear current ramp of +/-200mA. The vertical amplifier is an H-Bridge type driver. Positive current flow (deflecting the beam above the centerline) is defined as current from +12V to Q1 to Rsense through the coil to Q4 to Ground. The negative current path is from +12V to Q3 through the Coil to Rsense to Q2 to Ground. The input to the vertical amplifier is the ramp voltage generated above. The objective of the vertical amp is to match the current through the vertical coil with the input ramp control voltage. Current through the vertical coil is monitored through the sense resistor, formed from R15, R16, and R17. Voltage across the sense resistor is measured with the differential amplifier U1B. This voltage is then used as the feedback voltage to the control opamp, U2A. Zero Adjust: The output voltage from the ramp generator is a ramp from 5.0V to 1.05V (nominal). The center of this ramp is 3.0V. Then, the output of the current sense diff amp must be offset by 3.0V. This is accomplished with the Zero Adjust Network, Resistors R9, R10, and R11. Vertical centering is then accomplished by writing a pattern to the CRT, and adjusting R10 to center the display. Service Manual 6200-43E Rev. D Welch Allyn Atlas Monitor 93 Appendix A Theory of Operation Size Adjust: Adjusting the current through the Vertical Coil changes vertical deflection. The voltage across the sense resistor is: Vsense = (Vramp-Voffset) / 1.02 (1.02 is the gain of the current sense diff amp) Current through the coil is equal to current through the sense resistor network. coil = Isense = Vsense / Rsense Then, adjusting the value of the sense resistor will change the current through the vertical coil. Vertical gain is then accomplished by writing a pattern to the CRT, and adjusting R16 to set vertical deflection. Horizontal Amplifier: Current through the transformer increases linearly as Transistor Q6 is On (I = VdT/L). When the transistor opens, the drain voltage kicks up, and the current through the Transformer coil flows through C9, L2, L3, and the Horizontal Coil to Ground The transformer quickly loses flux (reset time < 5uSec). Current continues to flow in load inductance, from Ground through Q6-diode, C9, L2, L3, and the Horizontal Coil to Ground. This current flow charges capacitor C9. The current decreases linearly to 0, then changes directions. This is due to the AC coupling capacitor C9 being charged to a negative voltage. Current flow is then from Ground through the Horizontal Coil, L2, L3, C9, and Q6 to Ground. The drive to MOSFET Q6 is AC coupled. This will prevent Q6 to be driven high in the event of a faulty driver on the CPU board. In order to get adequate deflection current (about +/-2.3Amps), 18.5V across the transformer coil is necessary. A “boost” winding is added to the transformer, then when the voltage on the transistor drain flys up, current flows into capacitor C11. C11 charges to a voltage determined by the turns ratio in the transformer. Horizontal Gain: Horizontal deflection is adjusted by changing the current through the Horizontal coil. Changing the series inductance in the Horizontal Deflection Path modifies the current. Increasing Horizontal gain is then accomplished by writing a pattern to the CRT, and adjusting the “width coil”, L3. Horizontal Centering: Horizontal centering is accomplished by rotating magnets mounted on the CRT Yoke assembly. 94 Welch Allyn Atlas Monitor Service Manual 6200-43E Rev.

Video amplifier circuit. Recorder Electronics Overview: Atlas includes a thermal strip chart printer (optional on Model 200 and 210, standard on model 220). The user can print either annotated waveform data or Patient trend information. The printer specifications are: Paper Size: 56 or 58mm (2 1/4 inches) Printhead Width: 54mm (2 1/8 inches) Resolution: Vertical: 8 dots/mm, (200 dots/inch) Horizontal: 12 dots/mm (300 dots/inch) Chart Speed: 25mm/sec (1 inch/second) The main CPU controls the printer. Data timing, clock signals, and strobe widths are all generated by the FPGA on the CPU board. These signals are buffered on the recorder board (inverter U5), before transmission to the printhead. Power Supply – 24 Switcher It is necessary to generate 24VDC for the print head and motor. The input to the 24V switcher is either 12V from the AC/DC converter, or Battery voltage on the model 210/220 when AC is not present. The circuit is configured as a boost PWM using current mode feedback. The PWM controller is a UC3843A. The controller includes an internal 2.5V, 1% reference, and an external 5V, 1% reference. Nominal output voltage for the boost converter is Vout = [2.5V*(1 + 84.5K/10K)] = 23.6V. The converter will run at duty cycles over 50%, which requires slope compensation for a current mode controller. Slope compensation is added by summing in part of the oscillator signal with the current sense line. 96 Welch Allyn Atlas Monitor Service Manual 6200-43E Rev. D Theory of Operation Appendix A The PWM current limits on a cycle to cycle basis. The supply will be in current limit when the Isense line reaches 1V. Current limit is set to about 3.5 Amps from 12VDC or 5Amps from battery. Two control signals exist for the 24V switcher, n24Von and Rec-Supply-On. The 24V switcher is disabled when n24Von is high. This signal is controlled by the on board PIC processor. The switcher is held off at power up, and allowed to start after 50mSec. This is done to reduce inrush current at power up. The signal Rec-Supply-On enables power to the print head, and is controlled by the main CPU. Power is only applied to the print head when the recorder is running.

Print darkness can adjusted by controlling the time a dot is turned on. A thermistor is included on the printhead. This thermistor is nominally 30K, and decreases as temperature increases. The output of the temperature amplifier is a function of the thermistor voltage, Temp = .755*(1+R8/Rtherm).

D Theory of Operation Appendix A A/D Circuits M A/D A pulse width modulator is used as an A/D converter. The PWM runs at a 1.2KHz rate, synchronized by the A/D sync signal. A/D sync is low for 52.1uSec, high for 781.25uSec. Using the values shown, the integrator will ramp down 10.01V, and ramp up 25V. The voltage at the integrator output (U601-1) is limited to about 5V [5V*(73.2/83.2) + Vdiode)]. Then, the integrator starts at 5V and ramps linearly down to –5V. R605 3.48K Analog In U602-2 The analog input voltage to be digitized and the integrator output are the inputs to a comparator. The output of the comparator is low at the start of an A/D cycle, and switches high as the integrator ramp drops below the input voltage being digitized (see the timing diagram below). A/D conversion is accomplished by measuring the width of the PWM output signal. The A/D timer runs at 25.175MHz, then the A/D resolution is about 21000 counts (over 14 bits). Hysteresis is added to the comparator to avoid oscillations during switching. Note that since the output of the comparator is low at the start of the A/D cycle, a resistor divider is formed at the comparator input. This divider reduces the Analog-In signal by 0.75% [464K/ (464K+3.48K)].

ECG Circuits Overview Atlas provides a 5-wire front end, and will be compatible with both a 3-wire and 5-wire cable. Monitor (0.5Hz to 40Hz) Extended (0.05Hz to 100Hz) bandwidth are provided. The ECG amplifier always transmits 0.05Hz to 100Hz data to the CPU board (unless in baseline restore mode), additional filtering for Monitor Bandwidth is implemented in software. 104 Welch Allyn Atlas Monitor Service Manual 6200-43E Rev. D Theory of Operation Appendix A Defib Protect, RFI Filtering The ECG lead set includes a 1K resistor for current limiting. The neon bulbs act as a voltage clamp, limiting voltage to about 100V. Neons are chosen for their low capacitance and high DC impedance when off. Series resistors and diode clamps are used as a second set of protection circuits for the front-end amplifiers. Resistors R506, R507 and Diodes D506, D507, are used to reverse bias the lead clamp diodes (D501 to D505). Two passive RC filters are used to reduce susceptibility to RFI and ESU.

On a leads-off condition, the two 22Meg resistor drives the input of the buffer to 1.25V (VldsOff), and the amplifier output saturates high (at about 5.5V).

Lead select circuit. Differential Amplifier and Slew rate limit A traditional 3-opamp gain stage (U507 and U508) is used to construct the differential amplifier. The topology is modified slightly with the addition of slew rate limiting (U509). The ECG signal is slew rate limited to about 100V/sec. This is done to minimize distortion of the ECG trace in the presence or large pace pulses. The differential outputs of this amplifier stage are used as input to the Right Leg Drive amplifier. 106 Welch Allyn Atlas Monitor Service Manual 6200-43E Rev.

Differential amp/slew rate amp circuit. Right Leg Drive Amplifier The right leg amplifier performs two functions. First is to provide bias current to the input buffer amplifiers. Second, to reduce 60Hz interference (increase CMR). Patient Common mode signals are amplified and inverted, and this resultant signal used to drive the patient. Gain of the RLD amplifier at 60Hz is maximized, while keeping the system gain stable. The RLD output is mux’d to the appropriate wire depending on the chosen input vector. For example, when looking at Lead I (LA-RA), the RLD signal is switched to the LL buffer.

The High Pass Pole is set to 0.05Hz (a 3.3 second time constant). Large DC signals are sometimes present, for example, following a Leads Off condition. In order to quickly restore the ECG baseline, a transistor switch (Q504, Q505) is used to change the AC pole time constant to 0.33 seconds. Op Amp U508 provides the final amplification prior to the A/D converter. Service Manual 6200-43E Rev.

This probe has a negative temperature coefficient, R@30C = 1815Ohms, R@40C = 1200Ohms. The temperature amplifier is configured as a non-inverting gain stage. The positive input to the amplifier is a 1.25V reference. The output of the temperature amplifier is V = Ref*(1+Rfb/ Rthermistor). The A/D converter will digitize the An-Temp input, along with the reference voltage and ground.

D Theory of Operation Appendix A Impedance Respiration (Model 622/623 only) Overview Impedance respiration is accomplished by measuring a change of resistance across the patient’s chest during breathing. The RA and LA electrodes (Lead I) are uses to acquire the respiration signal. A current source is driven through the patient, and the voltage developed across the patient is measured. The change in resistance caused by respiration is small, in the order of 1 Ohm. This small change must be measured on top of a large baseline impedance, typically 100 to 1000 Ohms. Signal Source – Current Drive An AC current source is used as the input signal, a 34.8KHz square wave. The Power supply sync signal, at 76.8KHz, is transmitted across opto isolator U710. Flip Flop U701, configured as a divide by 2, converts this signal to a 34.8KHz. Current through the patient is about 150uA Pk-Pk, set by the output of U710 (5V) and the circuit series impedance, 69K including cable resistance. The impedance of the patient is small (<2K) compared to the series impedance and has minimal affect on the magnitude of the drive current. Diode clamps are used to protect the respiration circuits in the event of a Defibrillation pulse. f+5V -Clamp +Clamp Respiration Drive Circuit + C719 4.7uF D701 MMBD1503A E 2 3 Right-Arm D701-3 R703 31.6K C701-1 4 C701 1000pF RespDr+ 5 Q VCC D PR 1 R701 1.96K GND 2 C702 1000pF 3 R702 1.96K Left-Arm 3 U701A 74HC74 Resp-Clk 7 1 D702 MMBD1503A 1 Q CL CLK 6 14 2 D702-3 E R704 31.6K C702-1 Resp-Off RespDr- Figure A-36. Respiration drive circuit. Differential Amplifier and Peak Detector The AC current driven though the patient develops a voltage across the RA to LA electrodes. This signal is measured and amplified with the Differential Amplifier formed by U702A/B. This amplifier converts the differential voltage across the patient to single ended signal, with a gain of 16.8. Inverting this signal (U703A), and summing the original signal and inverted signal through the dual Diode D705 then forms a synchronous peak detector. Then, the voltage on C711 is the DC resistance seen across the RA to LA buffer. This baseline resistance is digitized, and if the signal is too large (>2.5K), a Respiration Lead Fault message is displayed. Note that this circuit measurement includes the two 1K resistors in the EKG cable set. This 2K resistance is subtracted in software before determining a leads off condition.

Gain and Filtering The DC content (baseline resistance) of the respiration signal is not needed, so the signal is next AC coupled, and additional gain applied before digitization. Low pass filtering is performed at this stage to reduce high frequency noise outside the respiration signal bandwidth. A baseline-reset circuit (transistor switch Q701) is used to quickly restore the high pass pole if excessive DC voltage is present, for example following a Leads-Off condition. fVcc B.W. = .06Hz to 16 Hz D605-C R720 100K 8 C712 3.3uF Resp-AC U703-5 5 6 R719 51.1K C713 0.1uF Q701-d - fVee E 7 An-Resp U703B AD712 R721 316K U703-6 E 2 Q701 MMBF4393L 1 + 4 R718 825K Gain =1000 B.W. = 10Hz R722 316 3 E Q701-g C714 .047uF E D706 MMBD1503A 2 Resp-Reset 3 1 R723 1Meg E Figure A-38.

This data is then processed to obtain the oxygen saturation percentage and pulse rate. 110 Welch Allyn Atlas Monitor Service Manual 6200-43E Rev.

The new 506 SpO2 sensor extension cable “DEC-8”, that can be identified by the purple connector, is backward compatible with the older 204/205 SpO2 PCB. The older 204/205 SpO2 sensor extension cable “EC-8”, that can be identified by the gray connector, will not work “it will not physically plug into the Atlas connector” with the new Nellcor 506 SpO2 PCB. The software was changed to version 2.5. The older sensors, that are indentified by the gray connector, will not work with the newer sensor extension cables even though the sensor will physically plug into the newer sensor extension cable “DEC-8”. The newer patient sensors have a purple connector and will work on the older sensor extension cables. 212 Welch Allyn Atlas Monitor Service Manual 6200-43E Rev.
