Testing and maintenance
2. Testing and maintenance
This chapter describes the test and maintenance procedure recommended for MAGLIFE light.
2.1
Functional control
Certain functions are tested automatically by the program.
- RAM test,
- EPROM test,
- CPU test,
- ANALOG/DIGITAL converter test.
In the event of a problem, a technical alarm message is displayed on the screen.
In the event of a communication problem between the monitor’s CPU and the different electronic
modules, a technical alarm message ("Time out") is displayed in the window corresponding to the
affected parameter.
2.2
Oximeter test
- Start up the MAGLIFE light device so that the Oximeter display is shown.
- Check that the MAGLIFE light device displays the message "sensor problem".
- Connect an SpO2 sensor to the front panel.
- Place the SPO2 sensor on your finger and check that the message changes to "pulse search", then
after the curve has appeared (approximately 10 secs.) the SPO2 value for SPO2 percentage and
B/min pulse should be displayed. Check that an SPO2 curve is shown and that there is a beep for
each pulse.
2.3
NIBP module test
2.3.1
NIBP check
Connect an NIBP tube with an adult cuff to the front panel connection and choose adult mode.
Put on the NIBP cuff and press the NIBP button (8).
Check that the NIBP pump motor begins to run and that the cuff begins to inflate.
Check that the NIBP screen window begins to indicate an increase in pressure while the cuff begins
to inflate.
Check that the pump stops when the screen window reads 180mmHg +/- 20mmHg..
The cuff should begin to deflate and after about 20 seconds should display the SYS/DIA/MAP values
in the NIBP window.
Deactivate the SPO2 function if necessary and check the P/min display.
2.3.2
Calibration of Non-Invasive Blood Pressure
- Connect a mercury column and a test cell to the NIBP socket on the front panel of the MAGLIFE
light device (if you do not have a test cell, an adult cuff rolled around a bottle in such a way as to
have little compliance can be used instead for the purposes of the calibration).
- Activate “Calibration” in the NIBP menu; the indication on the screen corresponds to the pressure
value measured by the NIBP module. Proceed with the measurement in several points, by
comparison of the MAGLIFE light indication and that of the external measurement device, across
the whole measurement range.

Operation of the MAGLIFE light device.
5.1.1
General information:
The MAGLIFE light device comprises the following elements:
The CPU POWER-board comprising a CPU section, a POWER section and all the connections
required for access to the different elements of control, communication, signalling and visualisation.
The board also supports and manages the SPO2 (OEM) and NIBP (OEM) options. The CPU provides
the digital and analog processing of MAGLIFE light and the POWER section supplies the different
power supplies required for the device to operate. All connections between the CPU section and the
POWER section flow through chevrons. They enable the CPU section to be electrically isolated from
the POWER section during testing of the latter. These connection lines are shunted through the
POWER section, before the chevrons, on a test connector.
N.B. : In normal monitoring mode, all chevrons are closed.
Keyboard circuits which serve as an interface between user and device.
A screen on which the curves and different parameters can be displayed.
The MAGLIFE light power source can be provided by a mains power supply module through a
connector located at the rear of the device and/or a battery permanently mounted in the device.
The battery is rechargeable through the power supply, and a light on the front panel indicates when
this is taking place.

The CPU POWER BOARD circuit (WSM0078A)
5.2.1
The power supply section:
5.2.1.1 Presentation
The power supply section of MAGLIFE light delivers, from the mains power supply modules or from
the lead 12 V–2Ah battery permanently mounted in the device, the following voltages:
U_MAINS
U_ALIM
+3.3V_TEST
+5V_TEST
+6V_TEST
EVER_VCC
U_BAT
It also charges the battery, from the voltage delivered by the mains power supply module through the
battery charger. Monitoring of battery charge status is provided by a system of comparators which
deliver the signals BATFULL_TEST, I_LOAD_TEST and –BAT_LOW_TEST. The signals
BATFULL_TEST and I_LOAD_TEST are used in combination to acknowledge the completion of
battery charging. The signal –BAT_LOW_TEST also acts on the On/Off status of the power supply. It
switches off the device hardware. This takes place when battery voltage is below 10 V. In parallel to
the surveillance by the system of comparators, battery voltage is continuously monitored by means of
the ADC of the CPU section.
Power supply On/Off control is under the control of the CPU section by means of the signals M/A_TEST and -HB0_TEST. They control establishment of the U_ALIM, +3.3V_TEST, +5V_TEST,
+6V_TEST and U_HALL_TEST voltages and activation of the battery charger.
The EVER_VCC voltage is always present. It only depends on the presence of one of the power
sources; mains power supply module or battery.
The protection fuse of the MAINS power supply is located in the mains power supply module, while
that of the battery is located on the CPU POWER-board.
5.2.1.2 Description of the input stage:
The power supply input of the device is protected against polarity reversal. This is carried out by
means of D1800. The output of this diode delivers the U_MAINS voltage, from which the battery
charger is supplied. It also supplies, via D1805, the DC/DC converter which produces the EVER_VCC
power supply voltage. In addition, it is also used as a control signal acting at the level of
U_HALL_TEST voltage command, and control of the power supply for the battery monitoring system
(U1801 and U1803).
The common point formed by the D1801 and D1802 cathodes delivers the COM_PWR voltage which
results from the U_MAINS and U_BAT voltage. The amplitude range of this voltage, according to the
power sources in place (mains power supply module or battery), can vary between 32 V and 9.5 V.
This is the voltage from which the U_ALIM switched power supply voltage is produced which supplies
the +3.3 V, +5 V and +6 V DC/DC converters. It is also the voltage from which is produced the
switched power supply voltage COM_PWR_CTRLD which supplies the battery monitoring system.
Similarly, the common point formed by the D1805 and D1807 cathodes delivers the IN_STARTUP
voltage which is resultant from the U_MAINS and U_BAT voltages. This voltage supplies the DC/DC
EVER_VCC converter.

5.2.1.3 Control of power supply voltages activation:
Switching of the U_ALIM voltage, from which are also produced the +3.3V_TEST, +5V_TEST and
+6V_TEST voltages, is carried out by means of the Q1800 switching transistor. It is controlled by the
U_ALIM_ON signal resulting from the logical operation carried out from the command signals M/-A_TEST, HB0_TEST and status signal –BAT_LOW_TEST.
The signal –HB0_TEST, active low, cuts the power supply voltages when an excessive ambient magnetic
field has been detected. Similarly, the signal –BAT_LOW_TEST active low cuts the power supply voltages
when the battery voltage falls below 10 V.
The table below summarises the status of the switching transistor depending on the command and status
signals.

5.2.1.4 Power supply voltage +3.3V_TEST :
The power supply voltage +3.3V_TEST is produced from the U_ALIM voltage, by means of a DC/DC down
converter built around U2000. It delivers a regulated voltage of +3.3 V +/- 5% and can provide a current of
1.5 A.
Activation of this voltage is controlled by the signal U_ALIM_ON.
5.2.1.5 Power supply voltage +5V_TEST :
The power supply voltage +5V_TEST is produced from the U_ALIM voltage, by means of a DC/DC down
converter built around U2001. It delivers a regulated voltage of +5 V +/- 5% and can provide a current of 1.2
A.
Activation of this voltage is controlled by the signal U_ALIM_ON.
5.2.1.6 Power supply voltage +6V_TEST :
The power supply voltage +6V_TEST is produced from the U_ALIM voltage by means of a DC/DC down
converter built around U2100. It delivers a regulated voltage of +6V +/- 5% and can provide a current of 1.2
A.
Activation of this voltage is controlled by the signal U_ALIM_ON.
5.2.1.7 Power supply voltage EVER_VCC :
The power supply voltage EVER_VCC is produced from the IN_STARTUP voltage, by means of a DC/DC
down converter built around U1903. It delivers a regulated voltage of +6 V +/-10% and can provide a current
of 300 mA.
The presence of this voltage is directly linked to the presence of the device’s power supply sources (mains
power supply module and/or battery). It is not switched. The EVER_VCC voltage mainly supplies the
device’s On/Off circuit and the ambient magnetic field measurement circuits.
5.2.1.8 Battery charger:
The battery charger comprises a DC/DC down converter built around U1900, a U1901 charge current
measurement circuit and a U1902 end-of-charge detector. It is powered from U_MAINS, which is the voltage
delivered by the mains power supply module. Its activation is controlled by the signal –HB0_TEST which
commands shutdown of the charger when the device enters an excessive magnetic field. It delivers a
voltage of 14 V and has a charge current limitation of 250 mA.
The charge current measurement is carried out across resistors equivalent to 0.5 Ω, R1907 and R1908,
inserted into the charger’s output line. The voltage developed on the terminals of the measurement resistor
is applied to the U1901 amplifier circuit. This delivers a voltage, amplified by plus 50, which is proportional to
the battery charge current. This is applied to the U1902B comparator, which has a transfer threshold set at
0.9, corresponding to a charge current of 18 mA. When this threshold is reached, the signal I_LOAD_TEST
passes to low status. In combination with the signal BATFULL_TEST, the signal I_LOAD_TEST controls the
battery charge indication light.
The table below gives the indication light status in accordance with the status of the signals I_LOAD_TEST
and BATFULL_TEST.

The outlet of the OUT_LOADER charger is equipped with protective elements, F1900 and D1806, intended
to protect the battery against an excessive charge current and to prevent battery voltage return on the
U1900 DC/DC converter outlet when the U_MAINS voltage is not present.
The F100 fuse placed at the outlet of the battery provides overall protection for the latter from the CPU
POWER-board.
5.2.1.9 Battery voltage monitoring:
Battery voltage monitoring is carried out by a system of threshold comparators which delivers the
BATFULL_TEST and –BAT_LOW_TEST status signals. The system of comparators is powered by a
switched voltage COM_PWR_CTRLD. It is switched by the Q1806 transistor which is controlled by the
U_ALIM_ON signal and/or the presence of the MAINS voltage. Similarly, the connection between the battery
and the system of comparators is controlled by the Q1804 transistor. The aim of this management system is
to control leakage currents drawn from the battery when the device is switched off and the mains power
supply module unplugged.
The battery voltage is applied to the divider comprised of R1811 and R1814 which provide a reduction of
4.32. The resulting signal is then applied to the inlet of the U1803B and U1803A comparators by means of
R1813 and R1819 resistors. These, in combination with R1809 and R1817, give hysteresis to the
BATFULL_TEST and –BAT_LOW_TEST comparators.
The switching thresholds of the comparators are carried out from the VREF_PWR voltage delivered by
U1801B and U1802. The voltage amplitude of the BATFULL_TEST and –BAT_LOW_TEST comparator
outputs are limited to EVER_VCC voltage using clipping diodes D1810 and D1811.
The signals generated by the comparators are exploited by the CPU section of the board. However, the
signal –BAT_LOW_TEST also acts at On/Off level by means of U1804. It causes switch-off of the device
hardware when battery voltage falls below 10 V.
)
PN : 0-48-0084
N.B. :
Hardware switch-off is the final level of device shutdown. Under
normal operation, device shutdown due to low battery is controlled
by the CPU section. It is achieved by monitoring of battery voltage
via the ADC. It takes place at 10.5 V.
So as not to damage battery lifespan, never leave it in uncharged
condition. In the event of device shutdown due to weak battery, the
battery must be recharged as soon as possible.

The CPU section
The CPU section contains the operating system (Linux), all associated specifications, keyboard
management and display, management of signals coming from the sensors (SPO2, NIBP, Hall) and
management of all inputs/outputs (peripherals).
It is comprised of a Coldfire microprocessor, memory (RAM and flash) and peripherals such as the USB, the
TFT controller, the clock (RTC), the sound (Buzzer) and serial connections.
A programmable component (CPLD) is used for address decoding (selection of correct peripheral),
generation of reset signals and certain control signals, and management of the keyboard and the rotating
button. An analog micro-controller (ANA) enables management of the SPO2 and NIBP sensor signals and
communication of the results to Coldfire.
The possible configurations are the use of an Oximeter and/or a sphygmomanometer.

The CPU board holds the following connectors:
• TFT screen: JP100 connector enabling use of a 6"5 TFT screen
• Backlight : JP102
• Speaker : JP103
• Rotating button : JP104
• USB connector : JP112
• Serial connection RS232 : JP105
• SPO2 sensor : JP108 and JP109
• NIBP sensor : JP107
• Keyboard board : JP101
• Battery : P101
• External power supply : JP106
An on/off circuit sends an on/off signal to the POWER section in order to start up and shut down the device:
When the ON/OFF button is pressed, the signal ON/OFF_BUT becomes active low and a 200 ms pulse is
created by the monostable 4538 (U100A). This pulse sends a 5V on/off signal to the POWER section, which
then supplies the different voltages. When the board is powered, after reset, it is the CPLD which creates a
5V –MONITOR_OFF_5V signal to take up the pulse. When the device is switched on, the on/off signal is still
at 5V. To shut down the device, the–MONITOR_OFF_5V signal created by the CPLD passes to 0V. Two
different cases can cause this switch to low status: A stoppage created by the software (confirmation of
device shutdown by user or low battery measurement) or a safety shutdown generated by the ON/OFF
button being pressed for at least 4 secs.
T filters (R-C-R) are present on all external signals.
A programmable logic creates a LOAD_ON signal from the I_LOAD_5V, BATFULL_5V and BATLOW
signals, coming from the power section. This signal makes the LOADING led flash during a battery charge
and makes it light up when the battery is charged.

5.2.2.10 Compact Flash
Compact Flash is a memory containing the applications, configurations (options) and trends. It acts as the
hard disk.
5.2.2.11 RTC
A battery-powered DS1501 (U1000) RTC (Real Time Clock) keeps the time on the device.
5.2.2.12 USB
The SL811 (U1100) USB controller enables implementation of a USB output to connect to a USB key or,
potentially, to connect a printer.
5.2.2.13 Audio
Alarms are generated by an AT89C2051 (U1201) microcontroller.
A serial communication transmits a frequency and an amplitude to this microcontroller. The corresponding
frequency is generated through a P1 serial port, and the sinusoid is smoothed out using resistors. The
amplitude of the resulting signal is changed using a DS1804 (U1203) digital potentiometer. The U1202B
operational amplifier generates a virtual mass. The signal is finally transmitted to a TDA1905 (U1200) audio
amplifier which provides the necessary power.
5.2.2.14 Hall sensors
Magnetic field measurement is carried out from a very precise voltage. A P1300 potentiometer enables the
output voltage of the LT1761 (U1300) regulator to be set at 5V +/-0.1%. Using a divider, two voltages, of
1.25 V and 3.75 V, are created and used as upper and lower thresholds for the magnetic field measurement.
These thresholds correspond to a field of –40 mT and 40 mT. If these thresholds are crossed in one of the
three field measurement directions, the signal –HB0 (active low) is generated, followed by abrupt device
shutdown. A MAX1295 (U1304) analog digital converter measures the magnetic field in the three directions.
It also measures battery voltage status, 6V and VCC voltage. For the field measurement, the ADC input
voltage has simply been divided by 2 (reference of 2.5 V). For the battery voltage measurement, the ADC
input voltage corresponds to the formula Vbat/k = Vbat/3 - 2.5.
5.2.2.15 UART
A UART TL16C754 (U1401) quad serves as a 3-serial-connection interface with the ANA microcontroller, the
buzzer and a test connector.
74LVX3245 (U1400 and U1402) tension transceivers are used as an interface between the 3.3 V and 5V
logical levels of certain signals.
5.2.2.16 Analog CPU
A AT89C51 (U1502) microcontroller manages communication between the SPO2 and NIBP sensors and the
microprocessor. To do so, it is interfaced with a UART (U1500) quad, and uses a demultiplexer (U1503) to
generate the Chip Select signals. A voltage supervisor (U1504) generates the start-up reset which initializes
all the components.

5.2.2.17 NIBP power supply
For the NIBP measurement, we use a CAS module.
Activation of the NIBP signal _ON_5V leads to generation of the +6V_CAS voltage.
The signal PUMP_5V is generated when the current consumed on the +6V_CAS voltage is high.
5.2.2.18 SPO2
For the SPO2 measurement, we use a BCI module.
The analog +5Va and –5Va voltages are realised using MAX1735 (U1702) and MAX883 (U1703) voltage
regulators and a 7662 (U1701) voltage converter.
The U1700A and U1700B amplifiers amplify the input signals coming from the sensors.
The two connectors JP1700 and JP1701 are the connections to the BCI module.

each of them. These codes are as follows:
- IC CLAVIER G. MAGLIFE LIGHT (CA : WSM0079B). [Left keyboard circuit]
- IC CLAVIER D. MAGLIFE LIGHT (CA : WSM0079C). [Right keyboard circuit]
- IC CONNEXION USB MAGLIFE LIGHT (CA : WSM0079D). [USB connection]
5.3.1
The left keyboard circuit
This has three push buttons, the actions of which are transmitted to the CPU via a 16P flat cable connection.
These three push buttons control the following functions :
- On/Off for a blood pressure measurement by cuff.
- Starting and stopping the audio alarms inhibition function (physiological and technical alarms).
- Partial On/Off of the device, known as “Standby”.
5.3.2
The right keyboard circuit
This has two push buttons which control the following functions:
- General On/Off of the device.
- Access to the main menu.
It also has the following three indication lights :
- Device operating light.
- Light indicating that the device is connected to the mains.
- Light indicating that the battery is charging.
All this information is sent via a 10P flat cable to the left keyboard and then to the CPU via the 16P flat cable.
5.3.3
The USB connection circuit.
This supports the USB connector and enables the USB plug to be attached to the rear of the device. This
circuit also contains pins which enable easy soldering of the cable connecting the USB to the CPU.

Technical description of the boards
5.4
The EXTERIOR ALIM (WSM0081A).
5.4.1 GENERAL INFORMATION:
The mains power supply module delivers, from the 50-60 Hz network, a rectified and filtered voltage
(MAINS) which may vary, according to the current output, between 18 V and 32 V. It is designed to operate
on 115 V and 230 V networks using a voltage selector integrated into the module board. The power
conversion is performed using a 25 VA toroidal transformer with double windings, primary and secondary.
)
N.B. :
For use on the 50/60 Hz - 100 V network, the EXTERIOR ALIM module
is equipped with a specific 100 V transformer.
5.4.2 DESCRIPTION OF THE POWER SUPPLY:
The mains socket of the module incorporates EMI filters and fuse compartments. For operations on the 115
Vrms network, the value of the fuses is 200 mAT. For operations on the 230 Vrms network, the value of the
fuses is 100 mAT.
The voltage selector is composed of four FASTON configuration cable terminals JP4, JP5, JP6, JP7. The
module is configured for use on 230 V mains when cable terminals JP5, JP6 are connected together. It is
configured for use on 115 V mains when cable terminals JP4, JP6 are connected together and cable
terminals JP5, JP7 are connected together.
3-10-0124
230 V version
Place 2 100 mAT fuses in the
compartment provided in the mains base
3-10-0124
115 V version
Place 2 200 mAT fuses in the
compartment provided in the mains base
A thermo-fuse integrated into the transformer provides protection for it against excessive heating. It acts
directly at the level of the primary by opening the power supply line.
The voltage delivered by the transformer secondary is double-alternation rectified by D1, D2, D3, D4 and
filtered by C3, C4.
The R1, R3 resistors constitute a limitation of the input current of the C3, C4 capacitors when the module is
switched on. As the filter capacitor terminals voltage increases, the Q2 transistor moves towards saturation
and makes the Q1 transistor conductive. In this state, the MAINS output voltage is fully operational. Another

protection, constituted by the CTP R11, protects the limitation resistors R1, R3 against overheating in the
event of short-circuiting of the filter capacitors.
In addition, the MAINS output voltage is equipped with a system for rapid discharge of filter capacitors C3,
C4. Its aim is to prevent prolonged presence of MAINS voltage on the module output. While the module is
under voltage, the signal taken from the D2 cathode blocks the Q3 transistor. In the absence of secondary
voltage, the Q3 transistor is on and the filter capacitors are discharged through R7, R12.

Definition
ECL:
The ECL is the board modification index. There are two types of ECL numbering:
- the first has three figures (PNN).
-P
: corresponds to the board version number and is incremented on each rerouting.
- NN : is incremented for each modification carried out on the board. NN falls back to 00
when the P version varies.
- the second has 2 letters (PN) of the board
6.2

-P
: corresponds to the board version number and is incremented on each rerouting.
-N
: is incremented for each modification carried out on the board. NN falls back to A
when the P version varies.
