General Precautions
n Electrical System Components/Parts
- Unless otherwise instructed in the Service Manual, be sure to turn OFF the power of the
machine and unplug the power plug before servicing. With the power plug still plugged, you
may experience electric shock, burn, or secondary damage due to short circuit even when
the machine is powered OFF. It should be noted, however, that some servicing procedures,
such as voltage measurement, cannot be performed under power-OFF condition. In such
cases, use due care to avoid electric shock, burn, or secondary damage due to short circuit,
as instructed in this manual.
- When servicing a board, be sure to wear an antistatic wristband to ground your body. If your
body is not grounded, static buildup on your body may damage electronic components on
the board.
FCR-MB201 Service Manual
Safe-1
Safe-2
n Drive System Components/Parts
n Grounding
- Be sure to turn OFF the power before servicing the gears, cams, and other drive
mechanism parts. Otherwise, your body or clothing may be entangled. However, there may
be cases where the procedures cannot be performed under power-OFF condition. In such
cases, use due care to avoid entanglement of your hand, foot, hairs, and clothing with any
rotating mechanism, as instructed in this manual.
- Safety provided by grounding is assured by properly establishing power cable and
additional protective ground wire connections and securing the parts with retaining screws.
To maintain safety, ensure that the parts and retaining screws removed for servicing
purposes are restored to states existing upon installation. After the parts and retaining
screws are restored to the above-mentioned states, follow the procedures set forth in this
service manual to verify that the retaining screws are securely tightened to properly secure
the parts.
n Heavy Objects
- Exercise due care regarding your working posture to avoid back pain during removal and
installation of heavy objects.
n Safety Devices
- Safety devices (such as fuses, circuit breakers, panels, and covers) should always be
enabled. Never attempt to make any alteration or modification that may impair their safety
features.
n Optical Parts
- When servicing the optical parts with the protective housings removed, be sure to turn OFF
the power switch.
- For dust removal procedures, observe the instructions described in the service manual.
- May not be sufficiently discharged even after power is turned OFF. When servicing the
parts, exercise due care to avoid electric shock hazards (not to touch the connector and
terminal carelessly).
n Other Working Precautions
- When performing servicing procedures with the protective housings removed under the
powered condition, carefully proceed with the procedures while checking the instructions
described in the service manual, and, when the procedures are completed, put the removed
protective housings back exactly where they were.
- Do not remove or install any part or component while the machine is powered, because of
possible electric shock hazards.
- When performing checks or adjustments under the powered condition, exercise due care
against electric shock or other hazards.
- Do not touch the parts (such as lamps) that remain at high temperature because you may
suffer burns.
- When servicing the printed circuit boards, be sure to wear an antistatic wristband to remove
static electricity built on the human body. Static electricity may cause damage to the printed
circuit boards.
- Keep clean the product labels, safety standards labels, product serial number indications,
and so forth attached on the machine, and do not peel them or put another label over them.

About Batteries
This equipment uses maintenance-free batteries as its internal power supply for all purposes
such as radiography, travel, electromagnetic lock release, and CR device operation. There
is no need to connect the power supply cable at every X-ray exposure. In addition, daily
maintenance is not required, such as replenishing the batteries.
As with all batteries, their capacity decreases with time. Periodic replacement is thus
necessary. The battery lifecycle is subject to change depending on the use environment or
use method. To prolong the battery life, we recommend using the batteries within the proper
range of use. In addition, see 5.2.2 “Checking the battery level” and 7.6 “Battery Charging
Operation" in Operation Manual to perform the charge operation as described.
<Installation>
DANGER
- Tools such as wrenches used to install the batteries should be insulated. Bare metal tools
may cause an abnormal short circuit accident to occur resulting in bodily injury, damage to
the batteries, explosion or ignition.
- Do not install the batteries in a room without ventilation. The batteries tend to generate
an inflammable gas upon excess charge resulting in an ignition or explosion if the room is
closed.
<Method of Handling and Operation>
DANGER
- Do not directly connect the positive and negative terminals with a conductive material such
as a wire. Be careful while using a metal tool such as a wrench and/or carrying the batteries
with metallic necklaces and hairpins not to make a short circuit. A short of the battery's
terminals may cause heat generation, an explosion or a fire.
- Do not solder directly on the batteries' terminal tabs. Soldering directly on the batteries'
terminals may cause a leak of electrolyte.
- Avoid the use of the batteries differing in capacity, type, history of use (charge/discharge
operation). These differences could cause electrolyte leakage or heat generation. Do not
remove or scratch the outer tube of the battery or it may cause an electrolyte leakage or
electrical leakage.
- Do not allow the batteries to be subjected to any strong physical shocks or jolts while
moving them. Treating the batteries roughly could cause leaks, heat generation, or an
explosion.
- Do not charge the batteries beyond the amount of the time indicated in the specifications,
or do not charge after the charge indication lamp indicates a full charge. Take the batteries
off the charger if the charge is not finished after the specified charge time. Over-charging
can cause leakage, ignition, or explosions.
<Storage>
CAUTION
- Store the batteries in a fixed position separate from metal or other conductive materials.
- Keep the batteries from rain water that could cause corrosion on the terminals of the
batteries.
- Keep the batteries right-side-up during transportation and do not give any abnormally
strong shock and jolt to the batteries. Transporting the batteries in an abnormal position
or handling them roughly could destroy the batteries or cause their characteristics to
deteriorate.
- When storing the batteries, be sure to remove them from the equipment or disconnect them
from the charger and the load, then store them at room temperature or lower temperature.
Do not store the batteries at direct sunlight, higher temperature or high humidity. To do so
cause the batteries short life, performance deterioration or corrosion on terminals.
WARNING
- Never dispose of the batteries in a fire as it may cause them to explode or generate a toxic
gas.
- Do not attempt to disassemble the batteries as it could cause leakage of sulfuric acid that
could bodily injure.
CAUTION
- To prevent accidents from happening, change any battery that is found to have an
abnormality such as a crack, a deformity, or leakage. The batteries must be kept clean and
free from dust to prevent loss of capacity or accident.
- If any abnormality of the charge voltage or the discharge voltage is detected replace the
batteries with new ones.
- Charging the batteries with an inverse polarity connection between the batteries and the
charger could cause electrolyte leakage, an ignition or explosion.

<Attention at battery storage>
<Disposal and Recycling>
a) Storage condition
Observe the following condition when the battery needs to be stored.
(1) Ambient temperature: -15°C to 40°C (preferably below 30°C)
(2) Relative humidity: 25% to 85%
(3) Storage place free from vibration, dust, direct sunlight, and moisture.
b) Self-discharge and refresh charge
During storage, batteries gradually lose their capacity due to self-discharge, therefore
the capacity after storage is lower than the initial capacity. For the recovery of capacity,
repeat charge/discharge several times for the battery in cycle use; for the battery in
trickle use, continue charging the battery as loaded in the equipment for 48 to 72 hours.
CAUTION
- Please write the information about battery recycling on the equipment, the package, the
carton, the instruction manual etc. in countries where legal or voluntary regulations on
battery recycling are applicable.
- Design the equipment such that exchange and disposal of the batteries can be undertaken
easily.
- Used batteries should be recycled. When returning used batteries, insulate their terminals
using adhesive tape, etc. Even used batteries still have electrical charge and an explosion
or a fire may occur, if proper insulation is not given on the terminals of the used batteries.
c) Refresh charge (Auxiliary charge)
When it is unavoidable to store the battery for 3 months or longer, periodically recharge
the battery at the intervals recommended in the table below depending on ambient
temperature. Avoid storing the battery for more than 12 months.
Storage temperature
Below 20°C
20°C to 30°C
30°C to 40°C
Interval of auxiliary charge
(Refresh charge)
9 months
6 months

d) Residual capacity after storage
The result of testing the residual capacity of the battery which, after fully charged,
has been left standing in the open- circuit state for a specific period at a specific
ambient temperature is shown in the figure below. The self-discharge rate is very much
dependent on the ambient temperature of storage. The higher the ambient temperature,
the less the residual capacity after storage for a specific period. Self-discharge rate
almost doubles by each 10°C rise of storage temperature.

Overview
1.1
Overview
This device is a tube head, inverter-type cordless mobile X-ray device combined with an
X-ray tube and high-voltage generator. A smooth and silent dual motor provides improved
drive operability, an easy-to-position telescopic arm and a remote control panel on the X-ray
variable limiting device allow easy positioning of the subject, and a high-precision focal spot
of 0.6/1.2 mm and 400 mA (maximum) creates sharp images for short-time radiography.
In addition, because the CR image-reading device is incorporated in the equipment, you can
read and check the images of a patient immediately after radiography.
1.2
Features
(1) The CR device is incorporated
Because the CR image-reading device is incorporated in the equipment, you can read and
check the images of a patient immediately after radiography.
(2) 130kV for the maximum X-ray tube voltage and 400mA for the maximum X-ray tube current
This is suitable for chest radiography, which requires high X-ray tube voltage, and short
exposure times, which are required for infants. It is also possible to obtain images of various
areas of the body, and for a wide range of patients.
(3) CR systems featuring the following can be used:
- Clear and superior diagnostic capability X-ray images are obtainable thanks to the effect of
digital image processing.
- Plenty of X-ray diagnosis information is available by wide latitude for the incident X-ray.
- The amount of X-ray exposure can be reduced, thanks to the high sensitivity of the system.
- The system is not affected by differences in radiography conditions, as long as they do
not vary too greatly, thanks to the effect of wide latitude and the automatic sensitivity
adjustment function. It is thus possible to obtain X-ray images with stable density for each
exposure.
- Radiography information, such as patient information, the region, and the menu is entered
from the console connected to the equipment.
(4) High-quality images provided via a small focal spot of 0.6 mm
Images with little penumbra are obtainable at a short source image distance.
(5) Tube head without high-voltage cables
A high-voltage generator is housed in the X-ray tube cabinet. No high-voltage cables are
required, and that eliminates mess around the tube head.
No need to bother about high-voltage cables during positioning and mounting operations for
radiography, and the operations possible to execute smoothly, in a shorter period of time.
(6) Easy-to-position telescopic arm
The telescopic arm can be intuitively positioned using longitudinal and back-and-forth
movement and rotation of the column. The forward/backward position of the arm does not
affect the upper and lower limits.
014-236-02E
MD-1
(7) Easy positioning
One-touch lock method via the electromagnetic brake adopted for supporting beam rotation
and arm lifting. Releasing and locking are easily performed by the switches on the operation
handles at the arm section and variable limiting device section.
(8) The remote panel provided in the X-ray variable limiting device section
Positioning is made easy thanks to the display and setting function for loading factor and the
drive switch (adjust mode) - all provided at the variable limiting device section - to enable the
radiographer to quickly change the loading factor and the position of the mobile base at the
patient's bedside.
(9) Easy drive operation based on the dual motor drive method
The dual motor drive method, which separately controls the left and right drive wheels, and
the responsive transport handle enable stable driving and turning.
The smooth and silent dual motor reduces noise of the equipment, reducing the risk of
disturbing patients when working at the bedside or moving the equipment at night.
Furthermore, you can set the movement sensitivity to one of four levels according to your
preference.
(10) Shock during drive reduced by the shock absorber-equipped casters
Shock absorber-equipped casters are adopted to the adjustable wheels of the mobile base
to reduce shock when climbing over a step, such as when going into an elevator, to improve
drive capability and equipment reliability.
(11) Touch sensor installed at the front of the mobile base
In narrow patients' rooms, the system stops advancing when obstacles are detected in front
of the mobile base.
This is useful for operation at the patient's bedside or parking in narrow spaces.
(12) Built-in battery-powered type
There is no need to connect the power supply cable each time thanks to the use of
maintenance-free batteries as the power supply. There is no need to add water to the
batteries.
(13) Small details taken care of:
- An LED display for the battery level makes battery checks easy.
- The X-ray ON indicator at the arm/tank catch section is turned ON at the time of rotor
startup and X-ray exposure so that the status can be checked from a location away from
the main unit.
- The nylon-coated transport handle can always be kept clean.
-When performing radiography at night, you can turn off the sounds for key input and X-ray
exposure.
-Emergency manual drive is available in case the electric drive fails.
(14) A variety of options
Considering exposure reduction, the X-ray protection barrier and the wireless hand switch
are available as options. Considering ease of use, the ultrasound distance meter can be
combined too.

As the power source for the CR reader unit (26), the DC/DC converter (31) supplies required
voltages, such as 24 V or 12 V. The DC/DC converter (24) and DC/AC converter (25) also
convert the voltage of the 192 V battery (1) to AC 100 V. This AC 100 V power source is used

Power Supply Circuit
Figure 2-2 shows the power supply circuit.
BT1 is made up of sixteen 12 V batteries connected in a series and is used for the power
source for all of the following: X-ray output, rotor inverter, the filament, drive circuit, constantvoltage power source, and CR.
The constant-voltage power source supplies power for control and the collimator.
BT1 supplies all the power for the equipment, so if BT1 does not have enough capacity,
the power source cannot be opened or closed. If BT1 falls to about 120 V or lower, the
equipment cannot be moved or used.

Power Switching Circuit
Figure 2-3 shows the power switching circuit.
Key switch KS1 is a changeover switch with a start switch. Turn this key switch to its START
position to turn on the power. The key will automatically return to its ON position.
When KS1 is turned to its START position, the constant-voltage power supply PWDC5 is
activated, and then the MPU of the PWR board starts.
As the MPU turns on the photocoupler PC4, the relay DR12 is turned on so that the battery
voltage continues to be supplied to the constant-voltage power supplies PWDC1, PWDC3,
and PWDC6. Even after the key switch returns from its START position to its ON position, the
circuit remains in the on state, enabling device operations for such actions as drive and X-ray
control. The MPU monitors the position of KS1 via PC3.
When KS1 is turned to its START position or ON position, the MPU turns on the photocoupler
PC5, and then the relay DR11 is turned on. The constant-voltage power supply PWDC4,
PWDC6, and PWAC1 are turned on and power is supplied to the CR.
Return the key switch to its OFF position after use to turn off the power. When the MPU
detects that KS1 is turned to its OFF position, it turns off the photocoupler PC4 and PC5
to cut off the whole power source of the unit. The unit is provided with an auto power-off
function. Also when no operation is performed for 30 minutes (the factory default setting)
after the last operation, the whole power source of the unit is cut off.
While the CR is turned on, the photocoupler PC4 and PC5 are kept their ON position three
minutes after the main switch is turned off or until the CR is turned off. When the cord reel is connected to commercial power, the commercial power is supplied
to the constant-voltage power supply PWDC5 and the MPU of the PWR board starts. The
battery is charged while the commercial power is supplied.
When the electromagnetic contactor KP1 is turned on, power is supplied to the electric drive
circuit and X-ray control circuit. The relay DR4 controls KP1. DR4 is usually turned on, but it
is turned off when an error occurs on the power circuit. When the EMERGENCY SWITCH is
turned on, the relay DR2 and DR4 are turned off and then power supplies is stopped to the
power circuit.

Rotating Anode Drive Circuit
Figure 2-4 shows the rotating anode drive circuit.
5D1 (CPU) on the CPU board (WZ62AB) outputs operation flag signal of rotating anode via
data signal bus to 5C (FPGA), and 5C (FPGA) generates drive signals of rotating anode for 6
IGBTs (Insulated Gate Bipolar Transistors) integrated to IPM (Intelligent Power Module) (IPM1)
on the MBDRV board (CZ65AR). These signals are received and isolated on
photocoupler - PC101, PC104 (for main drive coil side), PC102, PC105 (for the auxiliary
drive coil side), PC103 and PC106 (for common connection) - on MBDRV board.
The IPM (IPM1) outputs 60Hz rectangular voltage pulse (to the main coil: MA) and 90 degree
delay pulse (to the auxiliary coil: SA) from the connector "CNROT" on MBDRV board (CZ65AR)
to monotank (M-5CE-31) to drives anode on X-ray tube. The current of rotor coil is ramp AC
wave.
The output of the main coil is from CNROT-2pin to CNROT-1pin. And the output of the
auxiliary coil is from CNROT-3pin to CNROT-1pin. The auxiliary drive current has delay 90
degree compared with the main current to drive rotation force.
The main drive coil (MA) has a resistance of about 10 Ω [Ohm], and the auxiliary drive coil (SA)
has a resistance of about 30 [Ohm]. Measure the resistance at CNROT on the MBDRV board
(CZ65AR). The resistance can also be measured at the terminal (CN50) of M-5CE-31 (Tube
head).
CT11 and CT12 detect open circuits on the rotating anode drive circuit, and 5D1 (CPU) on
the CPU board (WZ62AB) reads and judges open-circuit detection signals. This open-circuit
judgment is performed 1.6 seconds after the hand switch is pressed down to its first position

Heating Inverter Gate Circuit
Figure 2-5 shows the heating inverter gate circuit.
The constant-voltage current control method is used to control filament heating.
The difference between the reference voltage from the CPU and the feedback voltage is input
into 6F (SG3524: regulating pulse-width modulator) for phase control to regulate currents for
preheating and heating.
The heating current is detected by the current transformer CT1 (threaded cable connected
from CNSM connector on MBDRV board to CN50 connector on Tube Head) and converted
into RMS (Root Mean Square) voltage on 4F3 (AD736: RMS to DC Converter). The detected
voltage of heating current is measured at 4F2-1. The detected voltage is approximately 0.5 V
during preheating, and approximately 1.1 V during heating (set at 100 kV).
The period of heating inverter oscillation is determined based on the time constant of capacity
and resistance, which is connected to 6F. The resistance connected 6F-6pin is variable using
2C3 (AD5282: Digital Potentiometer) controlled by CPU to adjust frequency. This frequency
is approximately 21 kHz.
The output of 6F connects to 5C (FPGA). 5C (FPGA) reads frequency of the 6F output signal,
receives operation flag from CPU via signal bus, and generates drive signal of filament
heating with dead time for 4 IGBTs integrated to IPMs (IPM2 for small focus and IPM3 for
large focus) on MBDRV board. The dead time of the inverter for the upper and lower arms is
approximately 2.5 μs.

Tube Voltage Feedback Circuit
Figure 2-7 shows the tube voltage feedback circuit.
The tube voltage is divided, and the voltage is then detected by the high resistor (200 MΩ)
on the high voltage side and by the detecting resistor (10 kΩ) on the low voltage side. Each
pick-up voltage of the tube can be measured between check pins kV+ and kV+G or between
kV- and kV-G, which are on the CPU board (WZ62AB), as a divided voltage. This voltage is
approximately 1 V at 40 kV or approximately 3.2 V at 130 kV. (For +kV measurement, the
polarity is reversed on the minus side.)
A ±kV voltage is added by 4F1.
The tube voltage is regulated by controlling the phase of the main inverter by means of
the application of differentials between the preset value of the tube voltage, divided tube
voltages, and differential correction voltage of the tube voltage.
The input voltage of 3C2 becomes the phase-controlled main inverter voltage and fluctuates
between approximately 1 and 4 V.

Main Inverter Gate Circuit
Figure 2-8 shows the main inverter (X-ray inverter) gate circuit. The figure illustrates the
circuit for the upper left side IGBT only because each IGBTs has the same circuit. 8C2
(VLA106-15242: Isolated DC-DC Power Supply) supplies +16V and - 8V power to 9C. 9C
(M57962AL: IGBT driver) insulated drive signal from CPU board, and drives IGBT gate. The
voltage of ON gate is +16V, and LD31(LED) illuminates yellow. The voltage of OFF gate state
is - 8V, and LD32(LED) illuminates green. Additionally, 9C detects IGBT over current (short
circuit) by monitoring collector (C1) voltage during IGBT is ON state. When IGBT over current
is detected, 9C-8pin (Fo) is turned to Low potential, and then the CPU executes the "E87"or
"E88" processing (inverter error).

Boost Chopper Circuit
Figure 2-10 shows the power circuit structure of boost chopper circuit.
The boost chopper circuit boosts up battery voltage (200V DC approximately) to 350V DC.
The output of battery connects to IGBT1 (middle connection) through boost inductor (DCR). The upper side of IGBT1 is used for blocking diode, and part of IGBT is off state anytime.
The lower side of IGBT1 controls output power and voltage.
Figure 2-9 shows the control circuit for boost chopper on MBDRV board.
The check pin "V_BUS" on MBDRV board has partial voltage of chopper output voltage, it
means that the bus (chopper bus) voltage is 77.7V per check pin 1V.
The period of chopper oscillation is determined based on the time constant of capacity and
resistance, which is connected to 15A2. This frequency is approximately 20 kHz.
2.10
Main Inverter Circuit
Figure 2-10 shows the main inverter circuit.
The main inverter is high frequency inverter that is composed of 2 IGBTs and 3 capacitors.
CS2 and CS3 are smoothing capacitor for the main inverter power bus. CS2 and CS3 applied
350V DC voltage boosted battery voltage by boost chopper.
CS1 is resonant capacitor connected to the main inverter output to boost up inverter output
using current resonance of the capacitor and inductance at high frequency transformer in
M-5CE-31(Tube Head).
SNB2 and SNB3 are snubber modules for absorbing surge voltage generated by IGBTs
switching.
R144 (power resistor) on the MBDRV board (CZ65AR) is a resistor to discharge from CS2
and CS3 when in service, and its time constant is about 30 seconds. Press SW1 on MBDRV
board to completely release electric charge, and check OFF state of LD18 (green LED)
before starting operation.
Never operate SW1 while the power is ON.

mAs Integrated Circuit
Figure 2-11 shows the mAs integrated circuit.
When the tube current flows through R152 and R153 on the CPU board (WZ62AB), the
current is converted into a voltage that can be measured. The tube current can be measured
at CNMA-2. At a tube current of 200 mA, a voltage of approximately 7.5 V appears. (The
voltage measured with a measurement instrument might fluctuate to a certain degree
because the voltage waveforms are not sinusoidal waves. Keep this in mind at the time of
measurement.)
After the mAs integrated voltage is compared with the mAs bias voltage by using the
comparator (6D3), cut signals are outputted to 6D3-7.
Remove CNMA and connect the mAs meter between CNMA-1 and CNMA-2 to measure the
mAs.

Electromagnetic Drive Brake Circuit
Figure 2-12 shows the electromagnetic drive brake circuit.
The relay DR21 determines which PWDC1 (DV24) or PWDC3 (V24) is used.
When the manual drive switch (PSI) is turned off, the relay DR23 is turned on, and then the
relay DR21 are turned on so that PWDC1 (DV24) is selected. The relay DR25 is also turned
on and the relay DR22 that controls ON/OFF of the electromagnetic drive brake turned on/
off in response to a signal from the MPU. In such a case, DV24 is supplied to the drive brake
switch PS6 and PS7 on the handle, and when PS6/PS7 is turned on, the relay DR24/DR33 is
turned on respectively. The signals of relay DR24 and DR33 are sent to the CPU board and
the MPU determines whether the electrical drive is performed or not. During electrical drive
(including adjust drive), the MPU outputs the signal that turns on the relay DR22 and the
electromagnetic drive brakes is released so that the electrical motor can be rotated.
When the manual drive switch (PS1) is turned on, the relay DR23 and DR21 are turned off
and PWDC3 (V24) is selected. The relay DR25 is also turned off and the relay DR22 that
controls ON/OFF of the electromagnetic drive brake R22 is turned on/off by drive brake
switch PS6 and PS7. In such a case, V24 is supplied to the drive brake switch on the
handle PS6 and PS7, and when PS6/PS7 is turned on, the relay DR24/DR33 is turned on
respectively. When either relay DR24 or DR33 is turned on, the relay DR22 is on so that the
electromagnetic drive brake is released.

Drive Circuit
Figure 2-13 shows the drive circuit.
The MPU controls drive by means of the phase detection of the transport handle, performed
by the sliding volume controls VR1 and VR2, which are attached to both sides of the
transport handle, and also through detection of motor rotating signals from the encoder RE
attached to the driving motor.
5D1 (MPU) on the CPU board (WZ62AB) outputs running drive signals, which are converted
into drive pulses by 5C (FPGA). The drive pulses oscillate at approximately 16 kHz output
into IPM2 and IPM3 through PC201 to PC302, which are on the MBDRV board (CZ65AR).
The photo sensor LS3 detects whether the arm/tank catch is switched on or off. The driving
speed is set up for drive mode when the arm/tank catch is switched to the on state and for
half-speed mode when the arm/tank catch is switched to the off state.
Pressing either of the adjustment switches (PS6 or PS7) on the RC board provided on
the X-ray variable limiting device moves the unit in the direction of the pressed switch for
approximately 15cm. The unit halts for five seconds after the 15cm driving.
IPM2 and IPM3 are intelligent power modules (IPM) with six insulated gate bipolar transistors
(IGBT) each, and the UV phase of each is used for the running drive.
- If the key switch is turned to the ON position while the handle is being held, alarms
A71 are displayed and the alarm sound used to prevent malfunction beeps.
- Turn the key switch to the OFF position first. Remove your hand from the handle,
turn the key switch to the ON position again, and then hold the handle to start
driving again.

Error Detection Circuit
Re-exposure processing (A61-A63)
If error E35 (Insufficient tube voltage), E36 (Tube over voltage), or E37 (Discharge detected)
is detected, re-exposure processing will be performed up to two times. In re-exposure
processing, the values of kV and mAs are the same as normal exposure processing (see the
following figure).
2.15.3
Tube over voltage limiter circuit (E36)
Figure 2-15-1 shows the tube over voltage limiter circuit. Divided tube voltages are measured
between check pins kV+ and kV+G as well as between kV- and kV-G, which are on the CPU
board (WZ62AB).
{MD:2.7_Tube Voltage Feedback Circuit}
Tube over voltage is separately judged with respect to the plus and minus polarities of the
divided tube voltage and the value of the divided voltage is compared with the limiter voltage
of the tube over voltage at 3C1-1. When a tube over voltage error is detected, 3E1-7 and/or
3E2-7 are set to "L".
At 3C1-1, adjustment is made so that an error is detected at a tube voltage of approximately
140 kV, and the following formula can be used to obtain the value:
Voltage at 3C1-1 = (Measured value at TP2 at 100 Kv x 1.4) ± 0.1
(Voltage at 3C1-1: From approximately 3.32 V to 3.34 V)
If error E36 is detected, re-exposure processing will be performed up to two times. If
radiography completes successfully during re-exposure, "A62" is displayed.
2.15.2
Backup timer failure (E06)
The backup timer is set for each radiography condition, and the CPU measures the exposure
time. If the exposure time reaches the set value, the CPU displays the error code "E06".

Main inverter over current limiter circuit (E86 – E88)
Figure 2-15-2 shows the main inverter over current limiter circuit.
12C2 on the MBDRV board (CZ65AR) is an IGBT driver. This main inverter over current
limiter circuit detects IGBT over current, turns PC21 off, and then sets PC4-14 to "H".
A drop in gate voltage caused by the RTC circuit for each arm activates each IGBT driver to
activate the main inverter over current limiter.

Filament over current / filament break detection circuit (E0A/E03)
Figure 2-15-3 shows the filament over current / filament break detection circuit.
The heating circuit uses the constant voltage current control method to detect over current
and breaks in the filament current.
At 5F2-7 on the CPU board (WZ62AB), a voltage of 1.1 V appears when the filament flashes
at 100 kV, and approximately 0.5 V appears during preheating.
When the voltage at TP45 is approximately 2.5 V or higher, 5F1-7 is set to "L" and a filament
over current error (E0A) is displayed.
The MPU constantly monitors the voltages of 5F2-7 and displays “filament break error (E03)”
when the voltage stays 0.2V or less for more than approximately one minute.
2.15.7
Weak discharge detection circuit (E37)
Figure 2-15-4 shows the weak discharge detection circuit.
Comparator 2D3 determines high-voltage weak discharge based on the differential value
obtained from the detected value in kV and the preset weak discharge value of 3D1, which is
on the CPU board (WZ62AB).
When weak discharge occurs at high voltage, a sudden change in the tube voltage increases
the differential value and shifts the value at 3D1-7 in the minus direction. This activates
comparator2D3, and then weak discharge detection is performed.
If error E37 is detected, re-exposure processing will be performed up to two times. If
radiography completes successfully during re-exposure, "A63" is displayed.

IPM1, IPM2, and IPM3, which are on the MBDRV board (CZ65AR), are IPMs for driving the
driving motor, X-ray tube rotor, and filament, respectively. When over current flows into each
element, the FO terminal of each element is set to "L" to perform over current detection (E81
- E83).

approximately 1.6 seconds, DR28, which is on the MBDRV board (CZ65AR), is turned on,
and then the READY lamp LP1 (green) provided at the top of the catch illuminates.
Pressing down the hand switch to its second position starts X-ray exposure, and then turns
on DR29, which is on the MBDRV board (CZ65AR). X-RAY lamp LP2 (yellow), which is
provided at the top of the catch, then illuminates. DR29 is in the on state for five seconds
after X-ray irradiation starts, and the x-ray exposure lamp LP2 (yellow) remains lit during that
time.

High-Voltage Circuit (Tube head)
Figure 2-17 shows the high-voltage circuit.
This circuit uses the Cockcroft-Walton method to apply high voltage to an X-ray tube.
Terminals N1 and N2 are neutral points, where current is detected to activate the mAs control
circuit (CPU board). In this method, leak current caused by the stray capacitance of the highvoltage generator's secondary coil does not flow through the neutral points, and therefore the
current (20 kHz) that is the same as the tube current can be measured between N1 and N2.
The turn ratios of the main coil and heating coil are 1:151 and 20:4.

This circuit is connected to the CPU board via serial data communication. The MPU reads
the status of the key matrix every 20 ms, always monitoring the status of each key switch.
The seven-segment LEDs and key LEDs are controlled through the dynamic method, which
is different from the method used for the operation panel. These LEDs continuously pulse, so
that they appear to always be on.
In addition, this circuit has an optional ultrasound distance meter circuit on the RC board
because of its structure.

Charging Power Supply Circuit
The battery charging circuit (see the following section) is activated at an input voltage of
AC 200 V. AC 200 V is generated by using a transformer (T1) to convert the voltage of a
commercial power. The circuit in this area is slightly different depending on the region where
it is to be used: Figure 2-20-1 shows a circuit for use in the United States, while Figure 2-202 shows a circuit for use in Europe.
The power supply cable is a cord reel (CR1). Power passes from the commercial power,
through the fuses (FU2 and FU3), into the transformer (T1), and is output as AC 200 V. Filter
LF1 is for EMC. In the circuit for use in Europe, a coil board (CZ21QD) is also added for
EMC. In addition, the circuit for use in Europe uses a relay connector connected to CNTJ1 to
allow internal switching of the power supply voltage between 220 V, 230 V, and 240 V.

Battery Charging Circuit
Figure 2-20 shows the battery charging circuit.
This circuit is activated at an input voltage of AC 200 V. Each power source on the charging
control circuit is generated within this circuit. For the power sources, +5 V and ±12V are used
for control and +15 V (floating type) is used for gates TR1 and TR2.
The whole circuit is controlled by 3C (MPU), and programs are input through DSUB5 and 1E
(RS-232C) from outside.
TR2 operates as a DC/DC converter to adjust charging voltage and charging current, and
TR1 operates as a switch to turn off the output when an error occurs.
The maximum charging current is 1.7 A, and the maximum charging voltage is determined
based on the charging modes and temperatures described in the table below. The charging
mode used immediately after turning the power on (the plug is inserted into the receptacle)
is the trickle charging mode. During trickle charging, the duration of the state in which the
current is kept at 1.5 A or more is measured. When that duration exceeds 50 minutes, the
mode changes to the cyclical charging mode. During trickle charging and cyclical charging,
when the voltage reaches its maximum value and the current drops to 0.6 A or less, the
mode changes to the auxiliary charging mode.

At temperatures other than those described in the table, the voltage is calculated by using
linear interpolation. Note that temperatures less than or equal to 0°C are interpreted as 0°C,
and that temperatures greater than or equal to 40°C are interpreted as 40°C.
The charging voltage is detected by 2F and is approximately 2 V at 200 V (2F-7). The
charging current is detected by 2D and is approximately 2 V at 0 A or approximately 4 V (2D7) at 2 A. The temperature is detected by the thermistor TH1 and 6E, so that the temperature
for the charging voltage is corrected.
Charging continues until the power supply stops (the plug is removed).

CR Interface
Figure 2-24 shows the circuit to interface with CR.
This interface is used to exchange data with the console via RS-232C communication. Data
such as X-ray conditions is sent to and received from the console during this communication.
Data is exchanged with the CR image reader by using on and off signals. When the CR
image reader is turned on, a short circuit occurs between DSUB2-1 and 6 to activate PC3.
When PC3 is activated, data is input into the MPU.
While the CR image reader is working, a short circuit occurs between DSUB2-5 and 9.
When this short circuit occurs, data is input into the MPU through PC4. The CPU prohibits
radiography and drive during the reading operation.

- After removing the covers, also remove the main power (200VDC) connector
CNMAIN for safety.
- After remove the main power connector CNMAIN, cover the connector of socket
side with the plastic cover (insulation material) because 200VDC of battery is
supplied to this connector.
CNMAIN
- To discharge the electrical charge remaining in capacitor, press PB1 (white button)
on the MBDRV board for at least 30 seconds by using an insulation stick etc.
without using your finger because there is applied 200VDC to the next metallic
terminal before discharging the capacitor. Should be wearing an insulation rubber
globe to push the PB1 to avoid the electric shock.
Check whether the LED on the PB1 is darkened to make sure that the electrical
charge was discharged.
When pressing the discharge button PB1, do not touch a metal part on the MBDRV
board; otherwise you might get an electric shock.
- Also, use a tester (direct current range) with test pin BUS+ and BUS-, which are at a
bit lower than PB1, to check the voltage.

■ REF.NO.
REF. NO. is a part number indicated in the
Service Parts Exploded Views. For parts
having different functions, they are clearly
distinguished in the REMARKS and SERIAL
NUMBER columns.
■ PART NUMBER
PART NUMBER is a code number that is
unique to each part. An alphabetic letter at
the rightmost position of the code number
has the following meaning.
○ For hardware
The alphabet denotes the version number
of a part. If parts have different version
numbers, they are upward-compatible.
○ For software
The alphabet denotes a difference in the
specifications. Parts differing in the suffix
are not compatible with each other. Version
number is omitted in the list.
■ PART NAME
PART NAME represents a general name of
a part.
■ QTY.
○ QTY. denotes the quantity of parts used
in each unit.
○ A part whose quantity is suffixed with -S
represents a small part that is shipped in
packs of 50. (Even if such a part is ordered
in quantity of 1, a pack containing 50 pieces
of that part is supplied.)
■ REMARKS
The REMARKS column indicates a unique
name of a part or relevant information of
each part.
■ SERIAL NUMBER
The units may contain different parts
depending on their shipment control number.
SERIAL NUMBER indicates the shipment
control number to which the relevant parts
are applicable. If the SERIAL NUMBER
column is blank, the parts are applicable to
all the relevant units. The shipment control
number is represented by lower five digits
of eight-digit number indicated on the rating
indication label.
■ REFER TO
The "REFER TO" column shows reference
sections concerning the part.Clicking
the reference section in the "REFER
TO" column jumps to the top page of
the reference section where the related
information is in.
■ Quantities of recommended spare
parts
It is recommended as a rough guide to hold
in stock a certain quantity of parts according
to the rank (A, B, C, D, E) assigned to the
parts, as follows. For periodically replaced
parts, hold them in stock separately. Adjust
the stock quantity of service parts depending
on the number of working units (N).
Quantity used in a single system : Q
○N=1
Rank A ＝ 1 ＋ Q × 0.3
Rank C ＝ 1 ＋ Q × 0.05
Rank D ＝ 1 ＋ Q × 0.02
○ 2 ≦ N ≦ 10
Rank A ＝ 2 ＋ N × Q × 0.3
Rank C ＝ 2 ＋ N × Q × 0.05
Rank D ＝ 2 ＋ N × Q × 0.02
○ 11 ≦ N ≦ 300
Rank A ＝ 3 ＋ N × Q × 0.3
Rank C ＝ 3 ＋ N × Q × 0.05
Rank D ＝ 2 ＋ N × Q × 0.02
■ Precautions to be Observed When
Returning Parts for Repair
When returning a component for repair,
pack it in the same manner as for the
supplied substitute, using the substitute
packing materials.
The use of different packing materials or
packing methods may incur damage to
packed component during transit.

How to deactivate wire rope fall prevention
5.
Adjust and check the position of the brake pawl.
Check whether the left and right sides of the brake pawl are released. If they are not
released, use a screw driver to move the metal plate that fixes the brake pawl left and
right and adjust the position of the brake pawl so that both sides are released.
When wire rope fall prevention is activated, you can deactivate it by using the following
procedure:
Never remove the screw except describing in this procedure. This mechanism might
not be restorable
1.
Brake pawl
Make sure that the safety brake is not engaged due to breaking of a wire.
If a wire rope is broken, the wire suspending the telescopic arm is loosened.
If the wire is broken, the telescopic arm falls when fall prevention is canceled, which
could result in injury or equipment damage. Take measures such as placing a piece
of wood for support to prevent the telescopic arm from falling, and then release the
brake. After releasing the brake, bring the telescopic arm down to the lowest level.
2.
Remove the telescopic arm cover.
3.
Release the safety brake.

the
safety brake.
Check the movement.
Make sure that the telescopic arm moves up and down smoothly.
7.
Attach the telescopic arm cover.
If the telescopic arm strongly hits the highest level of the stand, fall prevention might
become activated. Fall prevention might also become activated when the arm is
rapidly moved upward. (Fall prevention is activated by an extremely large force, but
is not activated by normal operation. When the arm is moved vertically, its speed is
likely to gradually increase within the movable range.)
A caution label is attached to the equipment (telescopic arm section) to alert the
operator to the above situation while the equipment is used.
4.
Remove any burrs on the brake rail.
Because fall prevention has been activated, burrs might be on the operating point of
the rail. Remove any burrs by using a file.

Creating images
1.5.1
Items to check beforehand
Before using the equipment, the following items must be checked:
- Use an IP with the largest size available in the facility.
- Make sure that no important image data stored on the IP can be exposed to light.
1.
Confirm that the READY window appears.
Items displayed on the RU operation panel differ depending on the settings for LANGUAGE
and SCREEN TYPE selected during setup of the equipment.
For details on the items displayed on the RU operation panel, see the service manual for
FCR-MB 201 RU.
2.
Perform quick deletion on the IP to clear the natural radiation and image data that
are stored on the IP.
3.
Expose the IP.
Make sure that the X-ray tube voltage is set to 80 kV. Otherwise, images cannot be
created correctly.
NOTICE

- Set the radiation dose as shown in the following table and expose two IPs with the largest
size available in the facility:
- X-ray tube
Tungsten X-ray tube
- Radiography dose
1 mR
- Maximum IP size
14" x 14" (35 cm x 35 cm) or
14" x 17" (35 cm x 43 cm)
- Example radiography
Distance: 1.8 m
conditions
Voltage: 80 kVp
mAs: 0.63 mAs
- For the first exposure, expose the IP by positioning it normally in relation to the X-ray tube.
For the second exposure, expose the IP by positioning it 180 degrees away (upside down)
in relation to the X-ray tube.
Checking X-ray performance

Checking images
3.
To check images:
- Before connecting to a LAN, use a grounding wire to discharge static electricity.
- MENU and other items displayed on the monitor will differ depending on the type
of IP. Use the MENU that is displayed by performing the procedure described below
when checking images.
1.
2.
Use the IP prepared in IN1.5.1 Items to check beforehand for radiography. From
the FCR-MB 201 Console menu, select QC/TEST, IMAGE-FORMAT or IMAGEFORMAT-2, and then SINGLE to output images.
{IN:1.5.1_Items to check beforehand}
Confirm that the images output to films or displayed on the monitor do not
contain any inconsistency.
Make sure that the density is consistent in the main scanning direction.
If the density of the images is inconsistent, compare the two films output with the
same size from the IP, and then determine whether such inconsistency was caused
by the equipment or the X-ray tube.
- If both films include inconsistency in density in the same direction
Normally positioned IP (the first film)
Check the image format.
Make sure that the white band of the output film is at least 2 mm shorter than the
actual size on the IP.
2 mm or less
Image frame
White portion
If the output film does not satisfy the required conditions, see the service manual for
FCR-MB 201 RU.
Depending on the scanned size and film size, the distance measured on the film
might differ from the actual size on the IP. In this case, you can obtain the actual size
by multiplying the distance on the film by the reduction ratio of the film. The actual
size on the IP can be obtained by using the following formula:
Real size on IP = Measured value x
100
Reduction ratio (%)
180-degree rotated IP (the second film)
In the above case, the inconsistency might have been caused by the equipment.
- If the unevenness locations in density are different
Normally positioned IP (the first film)
180-degree rotated IP (the second film)
In the above case, the inconsistency might have been caused by the X-ray tube.

1.6
Checking the S value
If the radiation dose measured by the dosimeter is less than 1 mR, adjust the
distance, tube current, and radiation time while keeping the tube voltage at 80 kV so
that the radiation dose is set to 1 mR. After checking the image, record the modified
radiography conditions as follows:
- Distance: cm
- Tube voltage: kV
- Tube current: mA (or mAs)
- Radiation time: second (or mAs)
Expose an IP at 1 mR, and then create the image by reading the data from the IP between
10 and 11 minutes after the exposure. Make sure that the displayed S value and the S value
that is calculated by the mean dose per 1 mR are within the allowable limits.
The allowable limits for the S value can be obtained as follows:
- Allowable limits for the S value when the equipment is operated by a user
Maximum limit: 200 x 1.5 = 300
Minimum limit: 200 / 1.5 = 133
- Allowable limits for the S value when maintenance or inspection is performed for the
equipment
Maximum limit: 200 x 1.3 = 260
Minimum limit: 200 / 1.3 = 154
The reason why the allowable limits for the S value when maintenance or inspection is
performed for the equipment are smaller than the allowable limits for the S value when
the equipment is operated by a user is to eliminate the need for another adjustment of the
equipment in a short period of time after the inspection or adjustment.
1.
If radiography conditions are unknown, modify them according to the values shown in the
following figure:
X-ray tube
Tube voltage: 80 kVp
mAs: 0.63 mAs
Distance: 180 cm
Place the center of a cassette to match the center of the X-ray irradiation field. Set
the X-ray irradiation field approximately 3 cm wider than the outer frame of the
cassette. Remove the cassette, and then place the dosimeter at the center of the
X-ray irradiation field.
X-ray tube
180 cm or more
Dosimeter
3.
Measure the radiation dose for five times by using the radiography conditions
obtained in step 2, and then calculate the mean value.
For example, if measured five values are as follows, the mean value will be 1.04.

FCR-MB201 Service Manual
IN-5
IN-6
Before performing a quick deletion, make sure that no important data is stored on the
IP.
6.
Using the radiography conditions obtained in step 2, perform X-ray irradiation on
a 14" x 17" (35 cm x 43 cm) or 14" x 14" (35 cm x 35 cm) IP.
Use an IP with the largest size available in the facility.
7.
Between 10 and 11 minutes after the exposure, output the image from the IP in
step 6. From the console (FCR-MB 201 Console) menu, select QC/TEST, IMAGEFORMAT or IMAGE-FORMAT-2, and then SINGLE to output the image.
8.
Obtain an S value per 1 mR by calculating the displayed S value (the S value on
the film or the console (FCR-MB 201 Console) monitor) and the mean dose value
obtained in step 3.
Minimum allowable limit
154
Maximum allowable limit
<
208
<

Make sure that the S value per 1 mR is within the range between
the minimum allowable limit and the maximum allowable limit.
If the S value per 1 mR obtained in step 8 is not within the allowable limits, see the
service manual for FCR-MB 201 Console to modify the settings, and then check the S
value again.
For example, to calculate the S value when the displayed S value is 200 and the
mean dose value obtained in step 3 is 1.04:
- Film to which image data is to be output
S value displayed on the film
- FCR-MB 201 Console monitor
Displayed S value
S value per 1 mR
9.
= Displayed S value
= 200
= 208
x Mean dose value

Make sure that the S value per 1 mR obtained in step 8 is within the allowable
limits.
For example, the S value can be calculated as follows:
