227 492 20 D - 0002

2 Functional description

The block circuit diagram of the entire instrument in Section 1.1 and the functional blocks of circuit diagram sheets (P-plans) describe the individual functional blocks.

2.1 Switching power suppl y

The switching power supply generates the fundamental device voltage for the PCB Control CS_CI and for the PCB NC Battery Charge.

It has the following input specifications: Input voltage range: 85 ... 264V ac

Line frequency range: 47 ... 65 Hz The output voltage is +26.5 V dc, the maximum load is 1.5A.

2.2 PCB NC Battery Charge

MAC1200 and MAC1100 with the option “Battery” can operate battery powered. With a new, fully charged NC battery, in Automatic Mode up to 50 ECG can be recorded.

The PCB NC Battery Charge, controls and monitors the charging process, depending on the status of the battery and the status of the device.

Section 2.2.1 and 2.2.2 is not valid for MAC1100 without option “Battery”.

2.2.1 Charging circuit for the NC battery

An integrated charging device is used to charge the battery. During charging it monitors the battery voltage function and switches over from rapid charging to trickle charging.

Applying the line power to the MAC 1200, or insertion of the battery activates the charging circuit. During a recording, the charging current is reduced. In standby mode, a depleted battery is fully charged within 4 hours.

Marquette Hellige GmbH MAC 1100/1200 V 1.1 Page 12

227 492 20 D - 0002

2.2.2 Device behavior depending on the state of battery charge

Depending on the status of the battery and the status of the device, the following behavior occurs:

State1: Battery depleted, line power supply is connected up:

Battery charged in rapid mode; when fully charged, switchover to trickle charging.

State 2: Battery full, line power supply is connected up:

Battery charged in rapid mode for some minutes till the charging circuit recognizes “battery full“, then switchover to trickle charging.

State 3: Battery depleted, no line power supply, device is switched on:

Device inoperative.

State 4: Battery full, no line power supply, device is switched on:

Device fully operative. When battery is almost depleded, the LEDBAT signal is activated to Indicate that the device should be charged by connecting to the line power supply. If the operation is continued without line power, MAC 1200 will shut down itself when a minimum level is reached to prevent the battery from a excessive discharge.

State 5: Battery depleted, line power supply is connected up, device is switched

on:

Battery is charged in rapid mode, device is fully operative, including recording. During recording, the charging current is reduced. If in this phase, a lot of recordings take place, the battery is not fully charged within 4 hours.

2.3 PCB Control CS_CI

The PCB Control CS_CI is the mainboard of the MAC 1200, the PCB Control CS_C is the mainboard of the MAC1100, which has not all memory circuit mounted. The mainboard accommodates the control functions of the device, except the line power supply and the NC battery-charging controller.

Marquette Hellige GmbH MAC 1100/1200 V 1.1 Page 13

227 492 20 D - 0002

2.3.1 Generation of internal power supplies

Logic power supply + 5V and + 3.3V

The processor core and the memory is a fully + 3.3V design. The interface functions to display, to RS-232, to the printing unit and to the ECG acquisition unit are supplied with + 5V.

Both the + 3.3V and the + 5V are generated separately by a clock-rated voltage controller. By using the „adjustable version“ of the voltage controller, both supplies are based on the same voltage controller. The output voltage is determined by appropriate dimensioning of the voltage divider at the feedback input of the voltage controller.

Standby supply + 5VSTB and + 3.3VSTB

The standby supply + 5VSTB supplies the ON/OFF Control, the + 3.3VSTB buffers the patient ECG memory when the device is turned off. Both supplies are generated together from one low-power linear regulator with low quiescent supply current.

Analog supply + 12V

+ 12V is used for the heating control and temperature monitoring of the printing unit, which requires only a current of a few milliamperes. This supply is generated by a linear regulator with feedback input.

2.3.2 Switch On/Off circuit

The Switch On/Off Circuit consists of the On/Off Control and the Voltage Control. The On/Off Control switches the device on or off by switching the device supplies

+UVERS and +USUPPSW. The On/Off Control is supplied from the + 5VSTB.

Device On Sequence:

The transition from Device Off State, or Standby State when line power is connected to Device On State can only be activated by pressing the On/Off button.

Device Off Sequence:

The transition from Device On State to Device Off State, or Standby State when line power is connected can be achieved as follows:

 pressing the On/Off button  when the control core activates the signal DEV_OFF,

Marquette Hellige GmbH MAC 1100/1200 V 1.1 Page 14

227 492 20 D - 0002

 when the voltage control applies the signal REG_OFF_, because the battery

voltage gets too low during battery operation. The Voltage Control controls the battery voltage during battery operation. The signal BATT_LEV2 indicates that the battery charge has gone down, and the

device should be connected to the line power soon. The signal BAT_LEV1 indicates that the battery has been discharged almost

completely, the device should be connected to the line power immediately, otherwise the device will shut down within few minutes.

If battery discharge is continued without connecting to the line power, the signal REG_OFF_ is activated and the device is switched off.

2.3.3 ECG recording and front-end processing

The patient input is classified as being cardiac floating and is defibrillation-proof. The patient leads are connected with a 15-pin connector with a special form for the

specified and released patient cables for the MAC1100/1200. The main element of the ECG recording and front-end processing is a set of chips

comprising 3 ASICs. Pace detection is realized by a separate circuit. Every disconnected electrode is detected by a special AC measurement, which

allows higher impedance between electrode and patient. N common-mode compensation ensures suppression of interference, at the same

time serving to improve the in-phase suppression of the input electrodes. To protect patients, the ECG recording and front-end processing are assembled as

floating components. Digital signals from and to the controller core are transmitted via opto-electronic couplers. The floating supply +/- 5V is generated by an isolated flyback converter from the + 5V logic power supply.

Marquette Hellige GmbH MAC 1100/1200 V 1.1 Page 15

227 492 20 D - 0002

2.3.4 Controller core

The actual core comprises the Motorola Power PC MPC821, which contains the following integrated components:

 chipselect logic  DRAM controller  SCC and SMC for RS-232  LCD controller  SPI Interface  I/O ports  Real-Time Clock counter register

In addition, the MPC821 contains a JTAG port with test and programming capabilities.

The MPC821 has the following additional power supplies:

 VDDSYN, filtered from the + 3.3V logic supply, for the clock generation.  KAPWR, generated from the + 3.3V logic supply, or from a battery when device is

off, used for buffering the RTC Counter Register. The clock generation for the MPC821 is realized by a quartz oscillator with

32.768KHz. The system clock CLOCKOUT is adjusted with the internal PLL register. The system frequency is 25 MHz.

The Watchdog /Reset Generation is implemented separately in an integrated system monitoring chip. It has the following functions:

 Power-up reset for the MPC821 when the device is switched on  Voltage monitoring of the + 3.3V and + 5V, with reset generation  Watchdog  Switchover to battery supply for patient ECG memory when device is switched off  Signal for access protection for patient ECG memory when device is switched off

The Reset Configuration defines startup conditions like boot port size and clock generation source.

Four LEDs indicate the device status in addition: LED1: active when a HRESET_ occurs LED2: indicator for the logic supply LED3, LED4: indicate internal software states

The control register comprises device control signals to switch off the device, control battery charging and display control signals.

The status register contains information on the device hardware configuration and the state of the battery charge.

Marquette Hellige GmbH MAC 1100/1200 V 1.1 Page 16

227 492 20 D - 0002

2.3.5 Real time clock

Since the internal Real-Time Counter Register of the MPC821 is used, no external Real Time Clock chip is required. The internal RTC Register is buffered by the voltage KAPWR.

2.3.6 Memory

The complete memory of the MAC1100/1200 is located on the PCB Control CS_C(I). The software of the device can be loaded through the JTAG Port during the production process, or for service purposes with the appropriate programming software through the RS-232 interface.

Program Memory:

Type: Flash, + 3.3V supply Organization: 1 Mbit x32, 4 Mbyte MAC1100: 0,5Mbit x32, 2 Mbyte Waitstates: 1 Waitstate

DRAM:

Type: EDO DRAM, + 3.3V supply Organization: 1 Mbit x32, 4 Mbyte Waitstates: 0 Waitstate

Patient ECG Memory:

Type: buffered SRAM, + 3.3V supply Organization: 256 Kbit x16, 512Kbyte MAC1100: No patient ECG memory Waitstates: 1 Waitstate

Configuration Memory:

The configuration memory is part of the program memory Flash. With special hardware and software protection facilities, write access to the Flash is only possible in the defined configuration memory of the Flash. Thus an external configuration Memory like an EEPROM is not required.

Marquette Hellige GmbH MAC 1100/1200 V 1.1 Page 17

227 492 20 D - 0002

2.3.7 LCD graphics display interface

For the LCD interface to the ¼ VGA monochrome LCD interface, the internal LCD controller of the MPC821 is used.

Controller Interface: For the digital control signals, delivered from the MPC821, only an output driver is

required.

LCD Power Supply:

The LCD power supply VEE of -23V is generated from the +5V logic supply. The generation starts after HRESET_ becomes inactive to ensure that the logic supply of +5V first is applied to the display.

Adjusting Contrast:

Contrast adjustment of the Display is accomplished with the contrast voltage V0. The level of V0 is controlled with the PWM signal BLCD_CONTR from the timer module of the MPC821. In addition, the contrast voltage is temperature compensated.

Backlight:

The LCD backlight converter for the CCFL tube is located on the PCB Control CS_CI too. The backlight converter is generated from the +5V logic power supply. The signal BLCD_ENBA switches the backlight on or off. The user can define the backlight active time in the configuration menu.

2.3.8 Keypad interface

The keypad interface contains the control register for 8 keypad columns and the receiving register for 7 keypad rows, and the control signals for the status LEDs: LED_LIN, LED_BATT, LED_START and LED_STOP.

Using the matrix of 8 x 7, up to 56 keypads can be detected. Identification of the key pressed is as follows:

The controller activates a column, activation is via low-level, then the row-register is read to identify the pressed key by a low-level. This procedure is repeated with the next column, till all columns have been activated.

Marquette Hellige GmbH MAC 1100/1200 V 1.1 Page 18

227 492 20 D - 0002

2.3.9 Printhead control

The printhead controller takes on the complete control of the 216-mm thermal printhead with a line width of 200 mm. The output rate to the printhead is 1000 /sec. The resolution in the Y-direction is 8 dot/mm, in the X- time axis up to 40 dots/mm.

Thermal Printhead Dot Control:

The MPC821 prepares a complete dot column and sends it to the FIFO. A complex PLD reads out a complete column of the FIFO and generates the digital control signals for the printhead, which are shifted in series.

The duration of heating a dot column is defined through the pulse width of the PWM Signal HEAT that is generated from the complex PLD too. In addition, the duration of heating a dot column is influenced by the thermal printhead monitoring.

Thermal Printhead Temperature Monitoring:

The thermal printhead temperature monitoring measures the temperature of the thermistor, located on the printhead. A constant current source effects a temperature-dependent voltage drop.

If a printhead temperature of 55°C is exceeded, the signal REC_OVHEAT_ is activated and the heating of the printhead is prevented by disabling the signal STROBE. Only when the printhead temperature drops below 50°C is the signal REC_OVHEAT_ disabled and the heating via the signal STROBE re-enabled.

In addition, a continuous reduction of the heating duration occurs with increasing printhead temperature, resulting in a regular typeface throughout the entire temperature range.

2.3.10 Motor control

Paper transportation for the speeds 5mm/s, 25mm/s and 50mm/s is driven by a stepping motor. The stepping motor is controlled by an integrated stepping motor driver circuit. The current for the motor is adjusted by the sense resistors of the stepping motor driver.

For the speed 5mm/s, the motor current is reduced, triggered by the signal LOW_SPEED.

The motor speed is controlled by the frequency of the signal RECTMR_STEP, which is generated by the timer unit of the MPC821. The driver circuit is enabled by the signal REC_MOTEN, the driver is powered from +22,5V.

227 492 20 D - 0002

2.3.11 RS-232 interface

The MAC1100/1200 has an RS-232 interface accessible with a 9-pin Sub-D connector. Except for the RS-232 driver chip, the interface is integrated into the control core of the MPC821.

The interface has the following attributes:

 hardware handshake with the signals RTS and CTS  or software handshake with XON/XOFF  transmission speeds from 4800 ... 38400 Baud  maximum input voltage range: +/- 15V  minimum driver output voltage: +/- 5V  maximum ESD interface protection: +/- 10kV

From version V1.1, MAC1100/1200 additionally provides a remote start input on the RS-232 interface. The MAC1200 US device additionally provides a modem power supply output on the RS-232 Interface.

2.3.12 Buzzer

The buzzer is an integrated signal generator with fixed frequency, directly operating from the +5V logic power supply. Activating and deactivating is controlled with the signal SPEAKER.

2.4 PCB Modem Suppl y CS_M

PCB Modem Supply CS_M generates a supply voltage of +8V dc, to operate a special GE marquette modem direct on the RS-232 interface on the MAC1200 without the need of an external power supply for the modem.

The Voltage is generated by a switching regulator with current limit and thermal protection from the +26,5V. The modem supply voltage +8V is accessible on Pin 6 of the RS232 interface. The protection against ESD is realized with a Transzorb diode on the PCB Control CS_CI

7.1.3 Safety Analysis Tests

7.1.3.1 General information

The suggested Safety Analysis Tests refer to the international standar d IEC 601- 1. The tests are generally performed wi th Safety Testers, on most of them, the measuring circuits according IEC 601 are al ready implemented. The following is a general description of the tests to be performed. For the handling of your Safety Tester follow the user manual.

The tests may be performed under normal ambient conditions of temperature, humidity and pressure and with line v olt ag e. The leakage currents correspond to 110 % of rated voltage for the tested unit. Most Safety Testers take this into account, otherwise the measured values have to be calculated.

Recommended Test Equipment

- Safety Tester for measurements according to IEC 601.

- Testing connector according to the following descri ption.

Marquette Hellige GmbH MAC 1100/1200 V 1.1 Page 56

227 492 20 D - 0002

7.1.3.2 Protective Earth Resistance Test

The power cord is to be included in the protective earth resistance test. This test determines whether the device has a power ground fault.

- The protective earth resistance from power connector to any protective earth

connected exposed conductive part is measured.

- Specs. of test circuit: AC current source 50 Hz/60 Hz of at least 10 A up to 25

A with limited output voltage of 6 V.

- If resistance is greater than 100 mOhm, the unit fails this test.

7.1.3.3 Measurement of Leakage Current

To perform the suggested measurements, the unit being tested has to be separated from any interconnection to a system. If the unit is part of a system, extended tests according to IEC 601-1-1 have to be performed. The following diagram shows the Measuring Circuit [M] required for leakage current. The reading in mV corresponds to µA (leakage current). The Safety Testers generally work with this Measuring Circuit [M] and the displayed values are already converted to leakage current.

7.1.3.3.1 Enclosure Leakage Current Test

This test is performed to measure leakage current from chassis to ground during normal condition (N.C.) and single fault conditions (S.F.C.). In all cases, the leakage current is measured from any exposed conductive parts to ground, the unit being tested has to be switched on and off.

Connect the unit being tested to your Safety Tester.

- During normal condition (N.C.), referring to the electrical diagram, measurements

have to be done under the following conditions:

* Polarity switch Norm and RVS * GND switch GND closed * S1 closed and open

227 492 20 D - 0002

- During single fault conditions (S.F.C.), referring to the electrical diagram, the

measurements have to be done under the following conditions:

* Polarity switch NORM and RVS * GND switch GND open * S1 closed

Test has failed if the measured values are greater than: N.C. S.F.C

100 µA 500 µA 300 µA (UL requirements)

7.1.3.3.2 Patient Leakage Current Test

This test performs a leakage current test under single fault conditions (S.F.C.) depending on domestic power outlet of 115 or 230 V AC as source into the floating inputs.

In all cases, the leakage current is measured from input jack of the unit

being tested to ground. Connect the unit being tested to your Safety Tester.  Referring to the electrical diagram, measurements have to be done under the fol-

lowing conditions:

* Polarity switch NORM and RVS * GND switch GND closed * S1 closed
