VII
the device. This is necessary to ensure the proper operation
of the system.
3. Precautions concerning installation and movement of the system
(1) Be sure to install the system on a level floor and lock the
casters. Otherwise, the system may move, and injure the
patient.
(2) Do not push the system from the sides. If the system is
pushed from the sides, it may fall down and cause injury.
(3) When the system is moved over a sloped surface, it must be
moved slowly by two persons. Otherwise, the system may
slide unexpectedly and cause a serious injury.
(4) Do not sit on the system.
The system may move, causing you to lose your balance
and fall.
(5) Do not place any objects on top of the monitor. They may
fall, causing injury.
(6) Confirm that the peripheral units are secured before you
move the system. Otherwise, the peripheral units may fall
and cause injury.
(7) When the system is moved over a step, exercise caution to
protect the system from falling. When holding the system at
the bottom to help move it over a step, take special care to
prevent hand injuries.
4.Do not vibrate the equipment excessively (when moving the
equipment); otherwise the mechanical parts (such as casters) may
be damaged. If the system is often moved on a bumpy floor, contact
the Mindray sales office, customer service department or
representative.
5. Do not connect this system to outlets with the same circuit
breakers and fuses that control the current of devices such as
life-support systems. If this system malfunctions and generates an
overcurrent, or when there is an instantaneous current at power
ON, the circuit breakers and fuses of the building’s supply circuit
may be tripped.
6. Always keep the machine dry. Avoid transporting this machine
quickly from the cold place to the warm place, otherwise
condensation or water drops may be formed, which will cause short
circuit.
7. If the circuit breaker is tripped or the fuse is blown, it indicates that
the machine or the peripheral devices have problems. In these
cases, the user cannot repair by him but contact the Mindray sales
office, customer service department or representative.

2.3 Power Supply Board
2.3.1 Introduction
The power supply board provides +5V (D+5V and A+5V), +12V, +13.5V, +3.3V, -5V, +1.5V,
+2.5V and program-controlled high voltage for the system.
The connection board connects the power supply board, main board and transducer board,
filters output voltage, and performs the linear voltage-stabilizing from +3.3V to +3V and from
+1.5 to +1.2V. The filter circuit is π-type.
The diagram of the power supply board is shown as follows.
C
onnection Board
2.3.2 Working Procedure
The AC input passes the EMI filter circuit and then the BOOST PFC circuit to be converted to
DC 370-410V. It then be converted to +5V, +13.5V, +12V and +24V outputs by the
two-transistor forward converter. The +5V output is the main feedback output of the converter
and others are auxiliary outputs of the converter. To obtain appropriate voltage and load
adjustment ratio, +13.5V and +12V are adjusted by the magnetic amplifier and +24V is
stabilized linearly. +5V is output directly as well as works as the input of +3.3V and -5V. +24V
is converted to the HV output by BOOST.
+5V, -5V, +13.5V and HV have the overvoltage and overcurrent protection. When the
protection takes effect for +5V, the whole power supply board stops outputting; When the
protection takes effect for -5V and HV, only -5V and HV are stopped outputting; When the
protection takes effect for +13.5V, +5V is not affected.
The power supply board also has the overtemperature protection function, which prevents
temperature of key power devices such as the transformer and MOSFET from exceeding safe
range when the system malfunctions.
Hardware Introduction
2-14
2.3.3 Circuit Description
The PFC circuit uses the control chip UC3854 from TI company and BOOST converter
controlled with average current mode. It also uses IRFPC60LC (600V/16A) from IR company
as the main switch tube and ISL9RL1560G2 (600V/15A ) from FAIRCHILD company as the
follow current tube.
The control chip U8 of the FORWARD converter is the voltage control chip MB3769A from
FUJITSU company, which can adjust voltage, limit current cycle by cycle, and has built-in
functions of soft start, low-voltage lock and protection lock. The transformer T1 not only
transforms voltage but meets requirements of safe isolation. The switch tube is SPA06N60C3
from INFINEON company, which basic parameter is 650V/6.2A. The +5V output is the main
feedback output of the FORWARD converter, +13.5V and +12V are adjusted by the magnetic
amplifier, and +24V is stabilized linearly by LM317.
HV is output from the BOOST converter, which uses the voltage control chip TL594 from
ONSEMI company. HV is controlled by 0-4V analog input signal and varies linearly between
30V and 140V with the variation of control signal.
+3.3V is output from the BUCK converter which is based on synchronous rectification.
EL7566 from INTERSIL company works as the controller, which integrates all control and
protection circuits and switch tube. Its rated output current is 6Amp and its conversion
efficiency can reach 96% at most.
+2.5V and +1.5V are the outputs of +3.3V after linear voltage-stabilizing, which is performed
by IRF7401 MOS from IR company and feedback control circuit. The MOS works at the
amplification area to realize linear stabilizing of low voltage.
-5V is obtained from +5V through BUCK-BOOST converter, which uses the control chip
TPS6755 from TI company. The chip, integrating MOS, produces negative voltage output
along with external inductors, capacitors and diodes and have current limit protection for
switch tube.
2.3.4 Protection Circuit
The power supply board has following protection functions: PFC output overvoltage protection,
output overvoltage protection, overtemperature protection, +5V/+12V/+13.5V/-5V/HV output
overvoltage/overcurrent/short-circuit protection, and other short-circuit protections.
1. When PFC output overvoltage protection, overtemperature protection or +5V output
overvoltage/overcurrent/short-circuit protection works, the whole power supply board stops all
outputs and locks. The board does not work until the system recovers from the failure and
restarts.
2. When +13.5V output overvoltage/overcurrent/short-circuit protection works, +13.5V and HV
outputs stop and keep locking. +13.5V and HV cannot be output until the failure is removed
and the +13.5V/+12V output load is disconnected.
3. When +12V output overvoltage/overcurrent/short-circuit protection works, the output stops
and keeps locking. The +12V cannot be output until the failure is removed and the
+13.5V/+12V output load is disconnected.
4. When +3.3V short-circuit protection works, +3.3V and HV outputs stop. They can recover
automatically after the failure is removed.
Hardware Introduction
2-15
5. When -5V overcurrent/short-circuit protection works, -5V output stops. When -5V
overvoltage protection works, the output stabilizes at some voltage (>-7V) exceeding the rated
voltage, not affecting other outputs, and can recover automatically after the failure is removed.
6. When HV overvoltage/overcurrent/short-circuit protection or +1.5V/+2.5V
overcurrent/short-circuit protection works, the output stops and does not affect other outputs.
They except HV can recover automatically after the failure is removed.
2.3.5 Maintenance
Before test or service, connect the power supply board as the figure below shows. The
electronic load A is necessary while the electronic load B is not. When adding the electronic
load B, ensure the load for 390VDC does not exceed 0.1A and is added only when loads for
other outputs are minimum.
You can add loads only for +5V, +13.5V, +12V and HV outputs. It is recommended to start
debugging when the load is a little heavier than the minimum and to increase the load during
the debug if necessary.
After connecting the board properly, you can locate the failure and service the board
according to the procedure shown in the figure below. The following procedure is just a basic
instruction and you should operate according to the actual situation.

Functional Diagram of LCD Inverter
The input of the inverter module is a 13.5V DC from the regulating board. In the inverter
module, the on-off MOSFETs are connected as a bridge circuit, which implements the
on-off operations driven by the main IC and convert the input DC to high voltage AC and
then transmit to the primary winding of the transformer. The secondary square wave of
the transformer is converted to sine wave after LC resonance to drive the CCFL gives out
light. The on-off signals control the on and off of the strip lamp throuth the enabling pin of
the main IC. The brightness of the light is controlled by the brightness signal, which will
control the duty cycle of square wave of main IC.
The inverter module is configured with protection circuit of open circuit, overvoltage and
overcurrent. Open circuit protection: When any of the strip lamps is open circuit, the
current feedback signal will be severely weak. If the feedback current does not stabilize
the CMP voltage even if the voltage of CMP rises to 3V, the IC will close two output
pulses and the circuit is locked for protection. Over current protection: When the output
current is too strong, the main IC will restrain the duty cycle of square wave after

receiving the feedback signal from the strip lamp to lower the current for protection.
Overvoltage protection: When the output voltage is too high, the main IC closes the PWM
driving after receiving the feedback signal from the strip lamp for protection.

2.4.2 Working principle of the regulating board
The functional block diagram of the regulating board is shown in FIG 2-21.
The VGA signal is transmitted to RTD2620 and completes the identification, amplification
and color processing. The signal is transformed to LVDS signal and then transmitted to
the LCD screen. U6 (MTV412) is MCU, which is responsible for the control of RTD 2620
and control of external operations such as buttons. U1, U3 and U4 provide working
voltage for DC-DC convert.

Appendix A Electrical Safety
Inspection
The following electrical safety tests are recommended as part of a comprehensive preventive
maintenance program. They are a proven means of detecting abnormalities that, if undetected,
could prove dangerous to either the patient or the operator. Additional tests may be required
according to local regulations.
All tests can be performed using commercially available safety analyzer test equipment.
These procedures assume the use of a 601PROXL International Safety Analyzer or equivalent
safety analyzer. Other popular testers complying with IEC 60601-1 used in Europe such as Fluke,
Metron, or Gerb may require modifications to the procedure. Follow the instructions of the
analyzer manufacturer.
The consistent use of a safety analyzer as a routine step in closing a repair or upgrade is
emphasized as a mandatory step if an approved agency status is to be maintained. The safety
analyzer also proves to be an excellent troubleshooting tool to detect abnormalities of line voltage
and grounding, as well as total current loads.

7- Mains on Applied Part Leakage
OVERVIEW 
The Mains on Applied Part test applies a test voltage, which is 110% of the mains voltage, 
through a limiting resistance, to selected applied part terminals. Current measurements are then 
taken between the selected applied part and earth.    Measurements are taken with the test 
voltage (110% of mains) to applied parts in the normal and reverse polarity conditions as 
indicated on the display. 
The following outlet conditions apply when performing the Mains on Applied Part test. 
Normal Polarity; 
Reversed Polarity 
TEST PROCEDURE 
Prepare   
To perform a calibration from the Mains on Applied Part test, press CAL (SOFT KEY 2).   
1) Disconnect ALL patient leads, test leads, and DUT outlet connections.   
2) Press CAL to begin calibration, as shown:   
If the calibration fails, the previously stored readings will be used until a passing calibration has 
occurred. Also, the esc/stop key has no effect during calibration.   
3) When the calibration is finished, the Mains on Applied Part test will reappear. 
Warning 
1) A 2‐beep‐per‐second signal indicates high voltage present at the applied part terminals 
while a calibration is being performed. 
2) High voltage is present at applied part terminals while measurements are being taken.

7- Mains on Applied Part Leakage
1) From the MAIN MENU, or with the outlet unpowered, plug the DUT into the 601   
2) Attach the applied parts to the 601PRO applied part terminals.   
3) Attach the red terminal lead to a conductive part on the DUT enclosure. 
4) Press shortcut key 7. The Mains on Applied Part test is displayed.   
5) Select the desired outlet configuration and applied part to test using the appropriate SOFT 
KEYS:   
6) Press START TEST (SOFT KEY 1) to begin the test. 
7) Press the print data key to generate a printout of the latest measurement. 
Note 
If all of the applied parts correspond to the instrument type, the applied parts will be tied 
together and one reading will be taken. If any of the applied parts differ from the instrument 
type, all applied parts will be tested individually, based on the type of applied part. This applies to 
Auto and Step modes only. 
Failure 
Check any broken of the AC/DC adapter and its cable. Replace a new one if any portion 
defective. 
Check any broken of the enclosure. Replace any defective part. 
Inspect wiring for bad crimps, poor connections, or damage. 
Test the wall outlet; verify it is grounded and is free of other wiring abnormalities. Notify the 
user or owner to correct any deviations. As a work around, check the other outlets to see if they 
could be used instead. 
Change another probe to confirm if the fail is caused by console. 
Inspect wiring for bad crimps, poor connections, or damage. 
If the leakage current measurement tests fail on a new unit and if situation can not be 
corrected, submit a Safety Failure Report to document the system problem. Remove unit from 
operation. 
If all else fails, stop using and inform the Customer Service Engineer for analysis and
