Introduction

General Information

This guide tells you how to install, service, and repair an Series 50A (M1351A) and an Series 50 IP/IP-2 (M1353A) fetal monitor. Throughout this book, the M1353A is referred to as the IP-2. This also covers the IP, unless stated otherwise. It describes the system hardware and software, and tells you how to test the system and diagnose operating and service problems.

It gives instructions for both the Series 50 A and the Series 50 IP/IP-2 monitors. The features available on the monitor you are installing or serv icing depend on which options have been purchased. If your monitor does not have a described parameter, you can skip that part of the instruction and move on to the next point.

What to do Next

Repair Strategy

The manual is for anyone who services an d repairs Series 50 A (M1351A) and Series 50 IP/IP-2 (M1353A) fetal monitors. You must understand English and be familiar with current conventional technical terms.

Famil iarize your self with the conte nts of this guide be fore attemp ting to install or service the monitor.

Reading operating error messages and the error lo g helps you to d etermine wheth er a fault is a hardware or software problem. Faults may be repaired by replacing a board when possible, or exchanging the monitor. Repair or replacement of components on the boards should not be attempted.

After any repairs you must carry out the following tests:

Performance test, by running the Self Test (see page 65).

Quick Test (see page 66).

Parameter Test (see page 68).

You must also perform the appropriate safety tests (see the section “Safety Testing” on page 100).

A series of preventive maintenance tasks and performance assurance tests must be carried out regularly to ensure the proper functioning of the monitor: these are described in “Regular Maintenance” on page 96.

Overview

This guide describes three different Series 50 Fe tal Monitor models:

M1351A Single Ultrasound model (with US and Toco channels).

M1351A Dual Ultrasound Twins model (with US1, Toco and US2 channels).

M1353A model (with US1, Toco and US2/ECG channels).

The M1351A single and double ultrasound model is for external monitoring of FHR an d uterine activity in the a nte nata l peri o d fr om ea rl y ge st ati on (appr o x im a te ly 20 to 25 w ee ks) to term. The M1353A is for monitoring FHR, including twins, maternal heart rate and uterine activity. FHR and uterine activity can be monitored externally in the antenatal period from early gestation to term, and in ternally th roug hout labor and delive ry. The basic capabilities of the three models are summarized in the table below.

The paper speed can be 1, 2 or 3 cm/min. The default for North America is 3 cm/min; the default for other countries is 2 cm/min.

Note— The ACOG technical bulletin on FHR monitoring states that “accurate

pattern recognition is difficult if not impossible at 1 cm/min and that 1 cm/ min is only recommended for more economic screening. When FHR abnormalities arise, the faster paper speeds will enhance FHR pattern recognition”. In addition, since a change in paper speed will result in a

change in the appearance of an FHR trace, care must be taken to ensure ALL monitors in your institution are consistently set at the same speed or speeds.

System Overview

The boards and their interconnections are shown in the following figure.

System Overview

Theory of Operation

The CPU board, which has overall control of the entire system, contains flash EPROMs containing all the s ystem sof tware. Th e softwa re for the Co mbined I nterface Bo ard (if one is fitted) is loaded from this ROM area.The signals from the transducers receive some analog conditioning on the Front End Board and are then digitized on th e CPU Board. The CPU Board includes a digital signal processor. The results of the processing are distributed to the outputs (for example, the Recorder, “traffic lights” and Combined Interface Board).

The monitor carries out a basic test every time it is switched on, and then at periodic intervals whil e it is on. There are two typ es of t es t:

Programs that check the hardware on each board.

Programs that carry out check sums on the individual portions of code that are loaded from the Flash EEPROMs.

When the moni tor is switched on , the initial reset generated by the power supply is fed to the CPU Board, where it is latched and passed to the other boards. Each board latches the reset to light its error LED. The LED can only be switched off by the CPU Board delatching it.

All error LEDs are on at the start of the tests. If a hardware error is detected on a board, its error LED stays on and its error code is shown on the display. (The error code is the last three digits of the bo a r d ’s part number.) But note that if any element in the display chain is not working, the errors may not be displayed. If a board passes its test, the LED goes out, and the next board in the sequence is tested.

The Power Supply Board, Front End Board and Recorder Board have no processor and so are tested by the CPU Bo a rd.

The boards are tested in the following sequence:

1. CPU Board.

2. Power Supply Board.

3. Front End Board.

4. Recorder Board.

5. Combined Interface Board (if one is fitted).

6. Modem Interface Board (if one is fitted).

The processor on the CPU Board runs a self-test program from the Flash EEPROMs to test certain function s of the CPU Board:

If the test fails, the red LED stays on and “Err 503'' is displayed .

If the test is successful, the red LED on the board goes out.

The current limits of the outputs of the Power Supply Board are then checked:

If any currents are out of limits, ``Err 502'' is displayed. Note that this does not necessarily mean that the Power Supply Board is faulty (for example, a short on another board could be drawing too much current).

If the test is successful, the red LED on the CPU Board is switched off.

All other boards are then tested. The red LEDs on the Front End Board and the Recorder Board are lit for about 1 s, and then switch ed off when the test is successful.

50 Chapte r 6 Theory of Operation

Booting and Self Tests

The Combined Interface Board and the Modem Interface Board both have processors that test the interface board once the DMA control logic has been checked.

The CPU Board boots a test program from the ROM to the on-board Digital Signal Processor (DSP) program RAM. The DSP then runs it. The program tests the DSP and its associated components, and writes the results to the DSP RAM. The CPU reads the RAM to find out the exit status of the tests. If the te st fail s, the LE D stays on and the err or code is displayed.

The signal processing software is stored as two programs in Flash EEPROMs. This carries out US/US or US/ECG functions. The CPU Board transfers the US/US or US/ECG program from its Flash EEPROMs to the program RAM of the DSP.

All the time the monitor is on, the CPU Board checksums the signal processing software and the Flash EEPROMs at 1-minute intervals. If the tests fail, the system is reset and rebooted. And every 300ms, a watchdog ASIC is fed patterns by the CPU Board 68000. If the ASIC does not receive a pattern, it resets the system.

Front End Board

M1351A (M1353-66501 and M1353-66511)

The Frontend board (M1353-66501 − single, M1353-66511 - dual) contains the analog circuitry for measuring all the possible parameters of the M1351A. One IC on the board provides the US timing and window control. Each type of transducer has a specific mode resistor which is recognized by the M1351A when the transducer is connected to an input socket. In this way, the user can be warned if a wrong transducer is connected. The marker cable is also connected to the Front End Board.

The frontend boards used with software at Rev E and higher are triangular in shape, not rectangular.

The demodulated LF signals are bandpass filtered (100 to 450Hz) and amplified by a software controlled gain of 180 to 1860 in eight steps. The FMP-LF path is independently demodulated, bandpass filtered and amplified by a facto r of 18.

Power Supply Board (M1353-66502)

The Power S upply Board operates as a linear regulated power supply with rectifier, capacitor and regulator. It generates the following voltages:

Regulated dc: Unregulated dc: +7V to +12V

±12V, +5V and +24V

±12V and +5V have an electronic short circuit curr e nt li mi t. The +2 4V dc regulator works

independently from the others. The +24V are used for the thermal printhead fed through the recorder IF-board. The internal +2. 5V reference voltage is generated from the +24V, so if the 24V section is inoperative, the rest of the power supply won’t work. The -12V regulator a lso needs the regulated +5V to work correctly. The reset (open collector output) is active low, when either the +5 V i s lower than +4.6V o r the + 24 V i s lower than +14.8V. If the +5V is highe r than 6.2V (this can be caused by any failure of the power supply or the other boards) the over-voltage protecti on is triggered and pulls down the voltag e to about

3.4V. This state can on ly b e re liev ed by sw itchi ng t he mo nitor o ff and on (i f the failu r e isn ’t still remaining).

The Central Processor Unit (CPU ) Board is the heart of the system and controls most other boards. The 68000 microprocessor and associated support ICs provide system functions; the bus control section controls the system bus. The board contains two Flash EEPROMs which contain all the system software.The board includes the following sections:

Microprocessor Section:

68000 microprocesso r.

Flash EEPROMs containing all system software and a boot program allowing

software upgrades via the Service Connector.

CMOS RAM memory, backed by a battery to store short time device settings etc.

A non-volatile EEPROM memory for permanent device and user settings.

A real-time clock, battery-backed and power-fail protected. The processor has access to all clock registers.

The multiplexer ASIC contains a watchdog function which monitors the operation of the microprocessor and restarts the system if it is not served at a constant rate.

AD/DA Section:

After system startup, the CPU starts the A/D control chip, which divides the signal fr o m the clock circuit and generates an i nterrupt every 2.5 ms.

The 68000 on the CPU Board then programs the multiplexer to select the analog channels for A/D conversion: the analog/digital conversion of up to eight channels is done by the multiplexer without further intervention by the CPU. A/ D conversion is by successive approximation. After the next interrupt, the CPU reads the results stored in registers within the multiplexer. The multiplexer also receives values from the CPU for audio output.

Display Controller

Backlights

LEDs

Signals at the keys are fed to the recorder board via the ribbon cable and are sampled by the controller. Display data is loaded from the recorder board to the display controller ASIC via a serial data link. The controller multiplexes this data to the LEDs and backlights. The multiplexer clock is served by th e recorder board. The clock speed is 3.2kHz to avoid interference between the US channel and the display multiplexer.

The Recorder Board provides the interfaces to the recorder and the display. The recorder interface consists of:

The parallel/serial converter for the thermal array data.

A heating timer to control the heating pulse for the thermal array. The voltage from a thermistor on the thermal array is A/D converted and the CPU programs the heating timer with a value which compensates the ambient temperature.

The recorder sensing hardware consis ts of a reflective light sensor th at detects the black marks on the paper and paper out. A battery supervisor circuitry checks for valid battery voltages, and this is read by the CPU Board. The display interface uses the same parallel/serial converter as the recorder. The board also contains test hardware which is not shown in the diagram.

+24V is blocked by capacitor and supplied to the thermal printhead.

Service Philosophy

Any errors produced are marked on the trace paper with the symbol and a specific error message is shown on the monitor display. In addition, the errors are reported on the system error log (see page 38 for instructions on how to print the error log). Read the error messages and system error log to determine whether the fault lies in the hardware or firmware. These problems can be repaired by board replacement or unit exchange. Do not

attempt component-level board repair.

Tests and Error Messages

Overview of the Service Tests

The system contains resident tests to enable monitoring of system status and errors that occur.

Power-On Self Test (see page 65) This is invoked whenever the system is switched on.

Performance Assurance Tests

• Parameter Test (see page 68) This checks the processing of the signal from the transducers.

• Quick Test (see page 66) This checks the display, recorder and complete instrument hardware and software.

Service Tests These are invoked by connec tin g the mo nitor to a PC an d usi ng a softw are servic e tool to assess, test and configure the system.

• Cyclic Test (see page 35)

• Permanent Test (see page 70)

Safety Tests These test the electrical safety of the monitoring system and must be carried out after upgrades and repairs. You must use a safety testing tool.

• Instrument Safety Test (see page 105)

• System Safety Test (see page 105)

• Safety Test Blocks (see page 100)

Performance Assurance Tests

Self Test The monitor automatically performs a basic-level self test when you switch it on. There are

two possible types of error that you might see. A fatal error prevents the monitor from functioning. A non-fatal error allows you to continue to work but warns you of a problem that must be resolved swiftly.

If a non-fatal error occurs (for example, if the batteries are low):

An error message is displayed for approximately 13 seconds.

Chapter 7 Tests and Error Messages 65

Tests and Error Messages

Err xxx , time and date are print ed on the paper after 13 seconds, and

then every 10 minutes.

(xxx is the number of the error message.)

Switch the monitor off and then on, and if the error occurs again refer to Chapter 8, “Troubleshooting Flow charts.” (If the reco rder is not on when the monitor is switched on,

Err xxx , time and date are printed when it is

switched on subsequently.)

If a fatal error occurs (for example, if a board is defective):

An error message is displayed for approximately 13 seconds.

After 13 seconds, the monitor will try to resta rt.

If the error occurs again refer to Chapter 8, “Troubleshooting Flowcharts. ”

Quick Test This tests the display, recorder and monitor hardware and takes approximately 15 seconds.

To carry out the test:

1. Switch on the monitor and the recorder.

2. Disconnect any transducers from the monitor (and if appropriate, switch off and disconnect the telemetry receiver).

3. Press

Test once.

Introduction

Troubleshooting Flowcharts

Troubleshoot ing is based on the interpretation of the error messages writ ten on the display and in the systems error log. See page 69 for a list of Operator Error Messages. For a list of error log messages and details of how to print the error log, refer to -38. There are cases, however, when no error message, or the natu re of the problem precludes the implementation of any automatic testing schemes. This chapter directs you towards the problem in a schematic approach. This method of troubleshooting may lead you to discover a blown fuse or a power supply failure.
