List of Components
The Force FX-8CAS generator is a self-contained unit, consisting of a main enclosure
(cover and base) and power cord. The main components of the generator are the
following:
• Front panel components—power switch; controls for setting the modes and output
power; a button for recalling the power settings and modes that were used last;
receptacles for connecting electrosurgical accessories; and indicators that alert you to
the current settings and patient return electrode status.
• Rear panel components—volume control; three footswitch receptacles; power entry
module; equipotential grounding lug; and three ports (serial port, RF activation port,
and expansion port).
• Internal components—Control (microcontroller) board; Display board; Footswitch
board; Power Supply/RF board; autobipolar board, low voltage power supply; fan; and
heat sinks.
Introduction
A handle is located on the underside of the chassis.
For details about the interaction of the main components and circuit board descriptions,
refer to Chapter 4, Principles of Operation.
General
Warning
Use the generator only if the self-test has been completed as described. Otherwise, inaccurate
power outputs may result.
The instrument receptacles on this generator are designed to accept only one instrument at a
time. Do not attempt to connect more than one instrument at a time into a given receptacle.
Doing so will cause simultaneous activation of the instruments.
Precaution
Do not stack equipment on top of the generator or place the generator on top of electrical
equipment (except an Argon Gas Delivery Unit II or a CUSA EXcel unit). These configurations are
unstable and/or do not allow for adequate cooling.
Provide as much distance as possible between the electrosurgical generator and other electronic
equipment (such as monitors). An activated electrosurgical generator may cause interference with
them.
Do not turn the activation tone down to an inaudible level. The activation tone alerts the surgical
team when an accessory is active.
Notice
If required by local codes, connect the generator to the hospital equalization connector with an
equipotential cable.
Connect the power cord to a wall receptacle having the correct voltage. Otherwise, product
damage may result.
Active Accessories
Warning
Electric Shock Hazard Ensure that all accessories and adapters are correctly connected and that
no metal is exposed.
Precaution
Accessories must be connected to the proper receptacle type. In particular, bipolar accessories
must be connected to the Bipolar Instrument receptacle only. Improper connection may result in
inadvertent generator activation or a REM Contact Quality Monitor alarm.
Notice
During bipolar electrosurgery, do not activate the generator until the forceps have made contact
with the patient. Product damage may occur.
Fire/Explosion Hazards
Warning
Danger: Explosion Hazard Do not install the generator in the presence of flammable
anesthetics, gases, liquids, or objects.
Fire Hazard Do not place active accessories near or in contact with flammable materials (such
as gauze or surgical drapes). Electrosurgical accessories that are activated or hot from use can
cause a fire. Use a holster to hold electrosurgical accessories safely away from personnel and
flammable materials.
Fire Hazard For continued protection against fire hazard, replace fuses only with fuses of the
same type and rating as the original fuse.
Introduction
Electric Shock Hazards
Warning
Connect the generator power cord to a properly grounded receptacle. Do not use power plug
adapters
Do not connect a wet power cord to the generator or to the wall receptacle.
To allow stored energy to dissipate after power is disconnected, wait at least five minutes before
replacing parts.
Do not touch any exposed wiring or conductive surfaces while the generator is disassembled and
energized. Never wear a grounding strap when working on an energized generator.
When taking measurements or troubleshooting the generator, take appropriate precautions, such
as using isolated tools and equipment, using the “one hand rule,” etc.
Potentially lethal AC and DC voltages are present in the AC line circuitry, high voltage DC circuitry,
and associated mounting and heat sink hardware described in this manual. They are not isolated
from the AC line. Take appropriate precautions when testing and troubleshooting this area of the
generator.
High frequency, high voltage signals that can cause severe burns are present in the RF output
stage and in the associated mounting and heat sink hardware described in this manual. Take
appropriate precautions when testing and troubleshooting this area of the generator.
Servicing
Precaution
Read all warnings, cautions, and instructions provided with this generator before servicing.
The generator contains electrostatic-sensitive components. When repairing the generator, work at
a static-control workstation. Wear a grounding strap when handling electrostatic-sensitive
components, except when working on an energized generator. Handle circuit boards by their
nonconductive edges. Use an antistatic container for transport of electrostatic-sensitive
components and circuit boards.
Notice
After installing a new low voltage power supply, verify that the voltages are correct.
Calibration
Precaution
To avoid inadvertent coupling and/or shunting of RF currents around the resistor elements, keep
the resistors at least 4" (10.2 cm) away from any metal surface including tabletops and other
resistors. This is especially true if several resistors are connected in series or parallel to obtain a
specified value. Do not allow the resistor bodies to touch each other
Notice
After completing any calibration step, proceed to the next step to save the values from the
completed calibration step.
Do not activate the generator with any load resistor higher than 10 ohms (10 Ω) while calibrating
the current sense gain. Otherwise, product damage will result.
Do not activate the generator with any load resistor lower than 1000 Ω while calibrating the
voltage sense gain for bipolar output. Otherwise, product damage will result.
Do not activate the generator with any load resistor lower than 3000 Ω while calibrating the
voltage sense gain for the Low and Pure cut modes. Do not activate the generator with any load
resistor lower than 2000 Ω while calibrating the voltage sense gain for the Blend mode.
Otherwise, product damage will result.
Do not adjust the current sense gain (I factor), the voltage sense gain (V factor), or the reactance
gain (Z factor) while the generator is activated.
After calibration, the generator will be ready to use only after you initiate the internal self-test by
turning the generator off, then on.
Calibrate the generator after you install a new battery. Calibration values are lost when the
battery is replaced.
Calibrate the generator after you install a new Control board. Otherwise, the default calibration
values are used.
Calibrate the generator after you install a new heat sink or replace components on the heat sink.
Component differences may affect output waveforms.
Calibrate the generator after you install a new Power Supply/RF board. Component differences
may affect output waveforms.

Functional Overview
The Force FX-8CAS generator is specifically designed to cut and coagulate (desiccate and
fulgurate) tissue during bipolar or monopolar electrosurgery.
During electrosurgery, RF current flows from the generator to an active electrode, which
delivers the current to the patient. The resistance to the current, provided by the patient’s
tissue and/or the air between the active electrode and the tissue, produces the heat that
is necessary for the surgical effect. The RF current flows from the active electrode,
through the patient’s body tissue to the return electrode, which recovers the current and
returns it to the generator.
Ultrasonic Electrosurgery
The Force FX-8CAS generator works in conjunction with the CUSA EXcel system for
procedures where ultrasonic electrosurgery is desirable. When you connect a CUSA
handpiece with CEM nosecone to the generator for ultrasonic electrosurgery, the
generator limits the monopolar output power automatically.
• The maximum power setting for monopolar cut is 100 W.
• The maximum power setting for monopolar coag is 70 W.
When you activate the handpiece for cut or coag output, the Low cut mode or the
Desiccate 1 coag mode is in effect automatically. The remaining cut modes and coag
modes are not available.
For more information, refer to CEM Mechanism Switch on page 4-14 and CEM Switch
Circuit on page 4-16.
Simultaneous Coag
Principles of Operation
When you simultaneously activate two monopolar instruments for coag output, each
receives a percentage of the coag power setting set for the selected mode. The amount
of power each instrument receives depends on the tissue resistance sensed by the
generator at each surgical site. Generally, the site with lower resistance receives
proportionately more power. The combined total output power does not exceed the
coag power setting.
You can also use a CUSA handpiece with a CEM nosecone for simultaneous coag when
you connect a monopolar instrument to the Monopolar 2 Instrument receptacle. For the
Force FX-8CAS generator, only Desiccate 1 coag is available; the maximum power setting
is 70 W.
Use one of the following two methods to activate the REM circuit:
• Turn OFF the Autobipolar mode and then connect the REM Polyhesive pad.
• Key the generator in the Monopolar mode once.
When resistance between the Patient Return Electrode receptacle pins exceeds 20 Ω, the
REM Alarm indicator flashes red, a tone sounds twice, and RF output is disabled. The
indicator remains illuminated red until you correct the condition causing the alarm. Then,
the red indicator light is extinguished and RF output is enabled.
For additional information, refer to REM Circuit on page 4-27.
Control Board
Refer to Chapter 9, Service Parts, for components and the Schematics Supplement for
Board Drawings and Schematics.
The Control board contains the circuitry that controls the generator, including the
indicators and switches on the Display board and the RF output stage on the Power
Supply/RF board. Firmware on the Control board performs many diagnostic and
initialization routines. Errors are reported as alarm numbers on the front panel.
The Control board interfaces with the Power Supply/RF board through a 96-pin card edge
connector. It interfaces with the Display board through a 64-pin ribbon cable.
Microcontrollers
Two microcontrollers on the Control board control the generator. These microprocessors
Principles of Operation
communicate with each other through a shared RAM. The main microcontroller (U5)
performs all system functions, except the time-critical real time feedback control of
generator RF output.
The feedback microcontroller (U11), which is a separate, dedicated microcontroller,
handles the time-critical real time feedback control of generator RF output. All system
analog signals are available to these microcontrollers.
A third microcontroller (U9) functions as an application-specific integrated circuit, or
ASIC. It generates the RF drive waveforms (T_ON\) for the RF output stage.
Main Microcontroller
The main microcontroller (U5) is an 80C562 that incorporates an 8-input multiplexed
8-bit A/D converter. The main microcontroller is responsible for overall system control. It
monitors all dosage error functions and safety circuits. It implements the user interface,
including activation control. It is primarily responsible for these functions:
• Segment display drivers and LED update
• Power control buttons, mode buttons, and the activation interface
• Serial port interface
• Alarm handling
• REM
• Audio control
• Memory control and storage (system alarms with time stamps; calibration values)
• Real-time clock control and interface
• Internal self-tests
• Communicating with the feedback microcontroller
Battery-Backed RAM
A socket on the Control Board contains a 3.0 V lithium button cell battery (BT) that
provides backup power to the DS12885Q + T&R Real-Time clock (U6). The device has
several features, including 114 bytes of general purpose Nonvolatile RAM not dedicated
to any special function within the device. This NV RAM is used by the processor program
as battery-backed memory.
Feedback Microcontroller
The feedback microcontroller (U11), like the main microcontroller, is an 80C562. It
receives commands from the main microcontroller and, when the generator is activated,
establishes the appropriate relay closures and activates RF output. It continually adjusts
the output signal of the generator by controlling the high voltage DC power supply and
the RF clock circuitry. It is primarily responsible for these functions:
• Scaling relay control and output relay control
• T_ON ASIC waveform control
• Leakage control (coag)
• Constant voltage, current, and power feedback control
• ECON initialization
• Real-time information update (actual voltage, current, power, impedance, effect
mode)
• Memory tests
• Communicating with the main microcontroller.
Principles of Operation
Shared RAM
The 4K x 8 external shared static RAM is provided by IDT71342LA (U50) DPRAM with
semaphore flags. The shared RAM allows the main microcontroller (U5) and the feedback
microcontroller (U11) to share common variables. It functions as a communications
interface between the main and feedback microcontrollers. It also provides additional
general purpose RAM to these microcontrollers.
I/0 Expansion
The FPGAs used in the Main and Feedback sections provide I/Os logic blocks and to
implement the glue Logic. The FPGA is interfaced to the controller P80C562 on the
parallel address and data bus.
The JTAG port is provided for programming the PROM (Configuration memory of FPGA)
in the Main and Feedback sections. Both the PROMs (U23 and U45) and FPGAs (U16-E
and U36-F) are connected in the JTAG chain.
into reset.
If the code received by the T_ON ASIC is not valid, the internal program sets an error flag,
deactivates all output signals, and remains in an error state until the system is reset.
different for each distinct output mode of the T_ON waveform generator. The main
microcontroller continually checks the T_ON average for compliance with the calibrated
value to ensure that the T_ON waveform generator is operating properly.
The T_ON average signal rests at 5 V when the generator is not activated and drops to
the calibrated value when activation occurs. The main microcontroller checks to make
sure the T_ON average signal is within ± 15 counts of the calibrated value.
During wave control in the coag modes, the T_ON average rises an indeterminate
amount. Due to this unknown, the T_ON average is allowed to rise to 253 counts, which
guarantees the T_ON waveform generator is still operating. The T_ON average is still not
allowed to drop below the lower limit of 15 counts mentioned above.
Audio Alarm
The audio alarm circuit is located on the Footswitch board. The audio alarm is controlled
by software and hardware.
• Software control is provided by the UP_TONE\ (microcontroller tone) and LO_TONE
signals generated by the main microcontroller in response to activation inputs, alarms,
and at power-up. These signals connect from the Control board to the Power Supply/
RF board through the 96-pin connector and then from the Power Supply/RF board to
the Footswitch board through the 16-pin footswitch ribbon connector.
• Hardware control is provided by the RF_TONE\ signal generated in the RF output stage
by RF sensing circuitry on the Power Supply/RF board.
Serial Interface
The RS-232 serial port is a software-polled interface to the main microcontroller (U5). It is
used for diagnostics and calibration. Transmission and receipt of command strings do not
stop real time processing, except as single characters are read from or written to the serial
port. The serial port is configured to 9600 baud, 8 data bits, 1 stop bit, with no parity.
This timing is derived from the main microcontroller oscillator frequency of 11.0592 MHz.
The Control board serial port signals connect to the Power Supply/RF board through the
96-pin connector. The signals are then connected to the 9-pin serial port connector on
the Power Supply/RF board.
Setting (% of
maximum
power setting) Maximum Allowed Output Power (not to exceed 400 W)
>25% to 80% setting + 25% of maximum power setting for that mode
>80% to 100% setting + 30% of maximum power setting for that mode
During closed-loop activation, the main microcontroller continually checks for a non-
functional high voltage power supply or RF stage. In doing so, the main microcontroller
verifies that ECON is greater than 90% full-scale while both the backup sensors (voltage
and current) are compared to ensure the difference between the voltage sensors and
current sensors is not greater than 50%, and to ensure that these sensors are not
saturated.
Principles of Operation
During spark control, the software makes allowances for the shift in frequency. The
voltage sensor returns a value that is approximately 20-25% high and the current sensor
returns a value that is approximately 10-15% low. At the start of a spark, the dosage
error buckets used by the software are reset.
maximum allowed output power using the previous table. While the generator is keyed,
the main microcontroller verifies that HV_SEN does not exceed this maximum ECON
value and the high voltage power supply is operating within acceptable limits.
Front Panel
The front panel consists of an injection molded plastic bezel with a membrane keyboard,
power switch, CEM mechanism switch, and REM connector with switch. These front
panel components interface with the Display board and the Power Supply/RF board.
Membrane Keyboard
The membrane keyboard is attached to the bezel with a high strength adhesive. It is not
removable. The membrane contains 17 metal dome push-button switches. Six of these
switches control the up and down sequencing of the power seven-segment LEDs (light-
emitting diodes). One switch controls the previous settings Recall function and nine
switches control each of the nine output modes of the generator.
The membrane also contains nine LEDs, one for each mode. A 25-pin flat ribbon cable
connects the membrane keyboard switches and LEDs to the Display board.
Power Switch
A double pole single throw switch snaps into the front of the bezel. This switch supplies
the AC mains current to the generator.
REM Connector/Switch
An internal REM connector and sense switch connects to the inside of the bezel with two
screws. Two cables leave this assembly. One cable is the actual REM connector; the other
cable is the output of the internal switch that senses the presence or absence of the
center pin on the REM plug.
Display Board
Refer to Chapter 9, Service Parts, for components and the Schematics Supplement for
Board Drawings and Schematics.
The Display board is located in the front panel assembly. It contains RF indicator lamps,
seven-segment LED power setting displays, REM alarm LEDs, and a CEM indicator LED.
The Display board switch circuitry includes the LED and lamp driver circuitry, power
selection switches, mode selection switches, the REM switch circuit, and the CEM switch
circuit.
RF Indicator Lamps
The RF indicator lamps illuminate during RF activation to visually indicate the presence of
RF power. Each of the three indicator bars (Bipolar, Cut, and Coag) on the front panel is
illuminated by four incandescent bulbs (LP1–LP12).
• LP1–LP4 illuminate the blue Bipolar bar, indicating bipolar activation.
• LP5–LP8 illuminate the yellow Cut bar, indicating cut activation.
• LP9–LP12 illuminate the blue Coag bar, indicating coag activation.
The RF indicator lamps are controlled by the BIP_LMP, CUT_LMP, and COAG_LMP signals.
These signals originate from the I/O pins of the main FPGA (U16) on the Control board.
Buffers in U1 turn the RF indicator lamps on and off. Resistors R1–R12 set the amount of
current flowing through the lamps when they are turned on. The value of these resistors
varies for each indicator bar, depending on the color of the bar, to make the different
colors of the bars illuminate with equal intensities.
REM Indicators
The REM indicator consists of two bicolor LED arrays incorporating one red and four
green LEDs per array. The LEDs are controlled by the REM_RED and REM_GREEN signals
originating from port A of the Main Controller section (FPGA U16, NOR Flash U17 and
SRAM U18) on the Control Board. The signals are buffered on the Display Board by driver
U1. Both the red and green LEDs are current limited by 100Ω resistors (R13, R14, R15,
and R16).
This circuit contains three display drivers for the LEDs and the seven-segment displays.
The LEDs indicate modes of operation, and the REM condition. The seven-segment
displays indicate bipolar, cut, and coag power settings.
Each display driver (U6, U10, and U14) can drive up to eight banks of eight LEDs by
multiplexing the time that each bank is turned on. The banks can be wired together to
increase the time that a group of LEDs is on, effectively increasing the brightness of that
group.
U10 drives the discrete LEDs and the CEM LED. These include green indicators for the
bipolar modes (Precise, Standard, and Macro), the cut modes (Low, Pure, and Blend), and
the coag modes (Desiccate, Fulgurate, and Spray). The anode of the mode selection LEDs
are tied to driver U10. By using pairs of the driver digit lines, the duty ratio for these LEDs
is effectively 1/4.
U6 drives the seven-segment displays that indicate power settings. U4 and U5 indicate
the bipolar power setting, U7–U9 indicate the cut power setting, and U11–U13 indicate
the coag power setting. The anodes of these displays are each tied to only one digit line
of the driver. The effective duty cycle is 1/8 for each seven-segment display.
U14 drives the seven-segment display U15, which indicates whether or not the generator
is in autobipolar mode. U15 is an amber display located in the left-hand position of the
bipolar window.
Some filtering components are associated with U6, U10, and U14. Bypass capacitors C3,
C4, C7, C8, C9, and C10 are connected between + 5V and DGND. C3, C4, and C10
have a relatively small capacitance value of 0.1 μF to filter higher frequency noise. C7,
C8, and C9 have a relatively large capacitance value of 47 μF to supply the large spikes of
current for the LEDs generated by the multiplexing action of the drivers, which typically
occurs at 250 Hz.
Resistor array R18 reduces the input impedance of the display driver inputs as seen by the
main microcontroller on the Control board. This rounds off the edges of these digital
signals, reducing high frequency emissions. The lowered impedance also reduces the
susceptibility of the circuit to noise from other circuits.
To read the switches, the main microcontroller asserts the desired BANK select line and
reads the state of the keyboard switch return lines KBD_D0 through KBD_D7. These lines
are read through port A of FPGA U16-D and Voltage Translator U20 on the Control
Board.
Footswitch Board
Refer to Chapter 9, Service Parts, for components and the Schematics Supplement for
Board Drawings and Schematics.
The Footswitch board is mounted inside the rear panel. It contains circuitry accepting and
decoding footswitch keying inputs and an audio circuit for announcing generator keying
and various alarm tones. The Footswitch board interfaces with the Power Supply/RF
board.
values of the resistors comprising the input divider are selected to provide a switching
threshold of approximately 750 Ω.
The divided voltage is then applied to the inverting input of one of the five comparators.
When the voltage at the inverting input exceeds the voltage at the noninverting input,
the open collector output of the comparator turns on, causing current to flow in the LED
of the corresponding optoisolator. This current generates an IR beam that causes the
associated photo-transistor to conduct. The collectors of the transistors are connected to
input pins of an I/O port on the microcontroller where they activate the desired mode of
operation.
Audio Circuit
The audio system consists of an audio oscillator, tone control signals, a volume control
potentiometer, an audio amplifier, and a speaker. A reference voltage (Vref) is used
throughout the audio circuit and is generated by dividing the +12 V power supply down
to about 2 V by R9 and R8.
The audio circuit annunciates the presence of RF output and provides an auditory
indication of alarm conditions. A potentiometer adjusts the volume of RF output
activation tones. The speaker volume cannot be turned off entirely. The volume of the
tone issued during alarm conditions is not adjustable.
The audio oscillator is enabled when UP_TONE\ or RF_TONE\ is pulled low. Diodes D1 and
D2 provide a wired OR function for the two signals. Because UP_TONE\ and RF_TONE\
are +5 V (logic level) signals, resistors R4 and R6 divide the +12 V audio power supply
down to about 4.85 V to prevent D1 and D2 from sourcing current into the Voltage
Translator U22 pins, which interfaces with FPGA U16-B, on the Control board.
When either UP_TONE\ or RF_TONE\ is enabled low, the voltage at the noninverting input
of U1B is pulled below the Vref threshold present at U1B inverting input, the open
collector output of U1B is turned on, grounding R31 and allowing U6A to oscillate.
U6A is a relaxation oscillator whose frequencies are determined by the RC time constants
of R30, C35, and C18. This design allows the oscillator to produce two distinct
frequencies that can be selected by the state of the LO_TONE signal.
• When LO_TONE is not asserted, R30 and C35 determine the frequency of operation
of the oscillator (approximately 900 Hz).
• When LO_TONE is asserted (+5 V), the voltage at the noninverting input of U1A
exceeds the 2 V Vref signal at the inverting input, turning on its output transistor. This
effectively connects C18 in parallel with C35 to produce a higher RC time constant
for the oscillator, which results in a lower audio frequency of approximately 700 Hz.
The ALARM signal selects the user-controlled audio volume or the fixed alarm level
volume. U1C and U1D are configured in an exclusive OR arrangement in which the state
of the output transistors of U1C or U1D is complementary.
In other words, the output transistor of one of these two devices is always on, but both
cannot be on simultaneously. Under normal operating conditions, the ALARM signal is
low, allowing the U1C output to float while the U1D output transistor is turned on.
The output of U1D creates a voltage divider through R11, R12 (the volume control
potentiometer), and R32 to attenuate the audio signal to levels acceptable for input to
the audio amplifier. R32 determines the maximum audio volume and R11 determines the
minimum audio volume. R10 determines the audio alert volume level. R34 provides an
alternate audio signal path in the event of an open volume control potentiometer.
When the ALARM signal is high, the U1C output transistor is turned on while the output
of U1D floats. When the U1C output transistor is on, R10 is pulled to ground and creates
a fixed voltage divider with R32 to produce the alarm volume level at the input to audio
amplifier U7.
Meanwhile, the output of U1D is allowed to float, thus removing the variable resistor
divider from the circuit. In this case, the volume control potentiometer becomes a small
resistance in series with the high impedance input from the audio amplifier, negating the
effect of the volume setting.
Audio amplifier U7 and speaker SP1 comprise the final stage in the audio system. The
audio signal is AC coupled to the amplifier by C25 to eliminate the need for well-
controlled input biasing.
The voltage gain of U7 is set to about 20 by floating its gain select pins. Because the U1
output signal is internally biased to Vcc/2, it is necessary to AC couple the speaker
through C27 to prevent the amplifier from DC biasing the speaker.
The Power Supply/RF board interfaces to other boards and components as noted below:
• AC input line filter
• Control board
• Autobipolar board
• Footswitch board
• Heat sink components (RF damping resistor, RF MOSFET, and high voltage power
supply MOSFETs)
This section contains the power entry circuitry, auto mains switching circuitry, AC/DC
conversion circuitry, and a DC/DC switching regulator.
AC/DC Converter
The AC/DC converter uses CR80 as either a doubler or full wave rectifier, depending on
the input voltage. In either case, an unregulated nominal 300 Vdc is provided to the
DC/DC switching regulator. Thermistors R32 and R33 provide inrush current limiting, and
fuse F4 provides protection against faults in the DC/DC switcher.
Capacitors C3, C10, C11, and C22 are an energy storage reservoir for the DC/DC
switcher. C29 is a high frequency bypass filter. Bleeder resistors R5 and R6 discharge the
capacitors when the AC line is disconnected or the power switch is turned off.
used for gain and integration, because common mode voltage limitations in U5’s internal
op-amp preclude its use over the full range of 0 to 5 V.
The internal op-amp is connected as a follower. SYS_ECON is compared to the feedback
voltage from the output divider (R34, R35, and R49), and an error signal (ECON) is sent to
the PWM microcontroller. In addition to the error signal, U7B and the associated R-C
networks provide lead-lag loop compensation to increase the bandwidth of the regulator
beyond that of the output L-C filter.
Note: U7A is used for random gain switching in the Spray mode and is configured for
unity gain in all other modes.
The output of U5 is a pair of 180 degrees out-of-phase signals that are pulse width
modulated by comparing ECON with the internal oscillator ramp waveform. At the start
of an oscillator cycle, an output is turned on. It turns off when the ramp voltage crosses
the ECON level. The two output signals from U5 (pins 11 and 14) feed the MOSFET
drivers (U3A and U3B).
R36 and C42 set the U5 oscillator frequency to approximately 170 kHz. C45 controls the
ramp-up of the pulse width at power on for slow start control. Transformer T2 limits the
power transformer primary current, protecting against faults in the DC/DC switcher
power stage and faults in circuitry downstream of the switcher.
The output of T2 is rectified (CR3–CR6), filtered (R30 and C30), and fed to the current
limit pin (pin 9 of U5). During an overcurrent condition the U5 current limit function
resets the slow start circuit, resulting in the output cycling from on to off until the current
falls.
Pin 9 of U5 is also used for remote shut down of the DC/DC switcher through U6A and
CR8. The shut down signal comes from the main microcontroller on the Control board.
The resistor divider on the high voltage DC output formed by R52 and R53 is used for
dosage error sensing.
RF Output Stage
Warning
High frequency, high voltage signals that can cause severe burns are present in the RF output
stage and in the associated mounting and heat sink hardware described in this manual. Take
appropriate precautions when testing and troubleshooting this area of the generator.
The RF stage consists of a single MOSFET power switch with associated gate drive
circuitry, an RF power transformer, tuning capacitors, an RF output L-C-C filter, output
directing relays, and topology selecting relays. Also included in this section are the RF
voltage and current sense circuits and a switched damping network for certain
operational modes.
The MOSFET gets its gating signal from the T_ON ASIC on the Control board. The T_ON
ASIC also provides the gating signal for the switched damping network.
When the topology selecting relays (K2 and K14) are unenergized, the RF stage is in the
Fulgurate and Spray coag modes; when both are energized, the RF stage is in the cut and
bipolar modes. For the Desiccate coag mode, K2 is unenergized and K14 is energized.
For voltage sensing, the two 10 k Ω resistors (R148 and R149) in series with the primary
of T13 work with the 100 Ω resistor across the secondary to divide the output voltage
down.
Depending on the front panel power setting, one of the four relays (K3 to K6) is switched
in to give optimum scaling. The four AD827 high speed op-amps, along with the
associated resistors, capacitors, and diodes, form a precision full wave rectifier circuit.
U11B is a high input impedance follower to prevent the rectifier circuit from loading
down the resistive divider.
U11A is a follower that adds phase delay, which improves balance in the rectified
waveform between positive and negative half cycles of the input signal.
The actual rectification is done with U8A and U8B. The rectified waveform is converted to
DC by the R-C filter after the last op-amp, with full scale being 5 Vdc.
The current sense circuit, which uses current transformers T6 and T8, works the same as
the voltage sense circuit. T6 senses bipolar current and T8 senses monopolar current.
Relay K7 selects the appropriate current. Note that the current scaling relays (K8 to K11)
switch at different power settings than the voltage scaling relays.
Cut Modes
In the cut modes, K2 is set so that diode CR2 is in parallel with the MOSFET body drain
diode, C34 and C41 are across the MOSFET, and the transformer primary consists of
windings 1-2 and 3-4 in series. K14 is closed so the series capacitor bank (C150–C152,
C158, and C159) is across the output.
In the Low and Pure cut modes, the T_ON\ signal is a continuous pulse train with a pulse
width of 846 ns and a frequency of 390 kHz. In this case, essentially two resonant circuits
operate in tandem.
The output L-C filter is tuned just slightly higher than the RF switching frequency,
achieving a high degree of filtering. The output is very sinusoidal over the full range of
load impedances. Capacitors C34 and C41 are tuned with the RF transformer primary so
that the flyback voltage appearing across the MOSFET at turn off is a half sine pulse and
returns to zero volts before the next cycle begins.
The T_ON\ pulse width is chosen to support this tuning. This zero voltage switching
improves the efficiency of the RF stage and is effective over a wide range of load
impedances.
The circuit topology of the Blend cut mode is the same as the Pure cut mode. In Blend
mode, however, the T_ON\ signal is an interrupted pulse train with a 50% duty cycle and
a pulse train repetition rate of 27 kHz.
For a given power setting, Blend gives a higher peak current, providing better hemostasis
than Pure or Low. To minimize ringing at the beginning of the off period of the Blend
waveform envelope, the damping resistor is switched on just before switching ends and
stays on for part of the off period.
Bipolar Modes
The circuit topology for the bipolar modes is essentially the same as the cut modes,
except the output voltage is tapped off C152 and the switching frequency is 470 kHz.
These differences allow for the higher currents and lower voltages required in bipolar
surgery while still maintaining the advantages of zero voltage switching in the MOSFET.
The T_ON\ signal is a continuous pulse train with a 423 ns pulse width.
Coag Modes
In the Fulgurate and Spray coag modes, K2 is set so that diode CR2 blocks reverse current
in the power MOSFET, C40 as well as C34 and C41 are across the MOSFET, and the
transformer primary consists of winding 1-2 only. K14 is open, keeping the series
capacitor bank (C150–C152, C158, and C159) out of the circuit.
In the LCF Fulgurate coag mode, the T_ON\ signal is a continuous pulse train with a pulse
width of 1.69 μs and a repetition frequency of 57 kHz. When the MOSFET turns on,
some energy is delivered to the output and some is stored in the T4 core. When the
MOSFET is turned off, the energy stored in the core rings out with a frequency of
591 kHz.
The frequency is set by C34, C40, C41, and the inductance of winding 1-2 of T4. CR2
blocks reverse current in the body drain diode of the MOSFET so that the power
waveform can ring negative.
This allows high peak voltages to be achieved at the output. In most cases, all the energy
stored in the transformer core during one switching cycle is delivered to the load before
the next cycle begins. The Fulgurate mode works the same as the LCF Fulgurate mode,
except the T_ON\ signal is a continuous pulse train with a pulse width of 1.69 μs and a
repetition frequency of 30 kHz.
The Spray mode works essentially the same as the Fulgurate mode, except the T_ON\
pulse frequency is randomized over the range of 21.6 kHz to 35.23 kHz. In addition,
amplifier U7A randomly varies the output amplitude by 10%. The ECON–GAIN signal
from the Control board changes the gain of U7A between 1 and 1.1.
To minimize ringing on the output voltage waveform at light loads, transistor Q7
switches in the 50 watt, 150 Ω heat sink mounted resistor in series with the transformer
primary for part of the RF switching cycle.
In the Desiccate 1 coag mode, K2 is closed and K14 is open. The T_ON\ signal is a
continuous pulse train with a pulse width of 2 μs and a frequency of 39 kHz. The output
resonates with a frequency of 308 kHz.
Principles of Operation
The Desiccate 2 and Desiccate 3 coag modes are treated by the microcontroller as
feedback controlled cut modes. Their operation is the same as Pure Cut described in this
section, except the power curves are different.
Output Relays
In all monopolar modes, K13 is closed and routes patient return current through the
Patient Return Electrode receptacle. K15 routes active current through the Monopolar
1/CEM Instrument receptacle. K16 routes the active current through the Monopolar 2
Instrument receptacle.
In bipolar mode, the Patient Return Electrode receptacle relay is open. Relays K12 and
K17 route bipolar current to the Bipolar Instrument receptacle.
All output relays are open when the generator is not being activated.
This sum is input into a pulse width modulator that sends its output (WAK\) to a NAND
gate. Thus, the T_ON\ signal is inhibited for up to four consecutive cycles. Without the
leakage control, the pulse repetition period is 17 μs. With the leakage control fully
activated, the total pulse train repeats every 84 μs with a maximum dead time of 60% or
51 μs.
REM Circuit
Components U17 along with R95, R96, R97, and C79 form a precision oscillator. R96 is
adjusted for the frequency that will produce maximum voltage amplitude (80 ± 10 kHz)
at the REM connector (J17). R98 is a temperature compensating thermocouple that
cancels temperature drift from the components forming the oscillator.
The REM transformer (T10) provides isolated reflected impedance sensing for tissue
impedance across the REM Polyhesive patient return electrode terminals (connected to
J17, pins 1 and 2). In addition to tuning the REM circuit, capacitors C155, C156, C169,
and C170 provide a return path for high frequency RF signals through C157 to the RF
output transformer. The REM transformer (T10) and capacitors C155, C156, C169, and
C170 form a resonant circuit with a nominal operating frequency of 80 kHz.
Pin 1 of T10 clocks the active synchronous rectifier formed by CMOS switch U28A. This
device is closed during the positive period of the REM_AC signal and open during the
negative period.
When the switch is closed, C122 is charged to the peak positive value of REM_AC. Then,
U31B amplifies, filters and buffers the charge on C122 to produce the R_SEN signal. The
microcontrollers monitor the R_SEN signal (which is a DC voltage proportional to
impedance) to determine the patient return electrode status.
IsoBloc Circuit
The IsoBloc circuit provides a means of detecting a switch closure in an output accessory
while maintaining electrical isolation between the generator output and ground
referenced circuitry.
The IsoBloc circuit consists of an isolated DC power supply, a comparator to detect switch
closure, and an optoisolator link from the output connected circuitry to the ground
referenced low voltage circuitry. Each handswitching output of the generator is
associated with its own IsoBloc power source and isolated signal paths.
Principles of Operation
Oscillator
The oscillator circuit consists of a chain of 74HC14 inverters. The output of the oscillator
yields a 67.5 kHz square wave that is applied to the input of three 4081 buffers (U29).
Power Supply
The three 4081 buffers (U29) drive three TN2404KL FETs connected to transformers
which are operated in a quasi-resonant flyback mode with their associated 6800 pF
capacitors.
The voltages at the secondaries of the three transformers are half-wave rectified and
referenced to three separate isolated grounds to provide -8 V for operating the isolated
activation circuitry.
Optoisolators
The isolated power supply voltages produced by the IsoBloc power supplies are
connected to the active output terminals of the generator. Handswitch activation is
accomplished by sensing active to CUT or active to COAG switch closure in a handheld
accessory.
Switch closure is detected by comparing the voltage across the switch to a divider
reference with comparators U32, U33, and U34. Current through the limiting resistors, in
series with the LEDs in the optoisolators, cause the LEDs to light.
The phototransistor, which is connected to an input on the FPGA U16-B, through the
U24 Bus Transceiver, in the main microcontroller circuit turns on, pulling the associated
input low. This is interpreted by the software as an activation request and the generator is
activated accordingly.
Autobipolar Board
Refer to Chapter 9, Service Parts, for components and the Schematics Supplement for
board drawings and schematics.
The autobipolar board is located between the front panel assembly and the Control
board. It consists of an 80 kHz signal generator, a tissue impedance sense circuit, and an
analog detection circuit.
To keep the RF output balanced and to protect against single point failure, two identical
serial resonant circuits (L1–L4, C1 and L5–L8, C2) were included. Both circuits operate at
80 kHz and provide a large, reactive impedance for the 470 kHz RF signal.
When RF is on, both bipolar relays on the Power Supply/RF board (K12B and K17B) are
closed. Therefore, C152 is put in parallel with tissue, changing the 80 kHz load. To cancel
out the reactance of C152, the relay K1 closes during RF generation, and L9–L16 are
placed in parallel with C152.
After unpacking or after servicing the Force FX-8CAS generator, set it up and
verify that it functions correctly.
Precaution
Do not stack equipment on top of the generator or place the generator on top of electrical
equipment (except an Argon Gas Delivery Unit II or a CUSA EXcel unit). These configurations are
unstable and/or do not allow adequate cooling.
Provide as much distance as possible between the electrosurgical generator and other electronic
equipment (such as monitors). An activated electrosurgical generator may cause interference with
them
Notice
If required by local codes, connect the generator to the hospital equalization connector with an
equipotential cable.
Connect the power cord to a wall outlet having the correct voltage. Otherwise product damage
may result.
1. Verify the generator is off by pressing the power switch off (O).
2. Place the generator on a stable flat surface, such as a table, platform, or Covidien
cart. Carts with conductive wheels are recommended. For details, refer to the
procedures for your institution or to local codes.
Provide at least four to six inches of space from the sides and top of the generator for
cooling. Normally, the top, sides, and rear panel are warm when the generator is used
continuously for extended periods of time.
Ensure that the generator rests securely on the cart or platform. The underside of the
generator contains four rubber feet and additional holes that allow you to reposition
the feet to ensure stability.
Use a Phillips screwdriver to remove the rubber feet from the generator.
Then, reinstall the feet in the preferred location.
3. According to the procedures used by your institution, connect an equipotential
grounding cable to the grounding lug on the rear panel of the generator. Then,
connect the cable to earth ground.
4. Plug the generator power cord into the rear panel receptacle.
5. Plug the generator power cord into a grounded receptacle.
Important
If the coag mode has been optionally changed to default to Desiccate or Spray, that
corresponding indicator illuminates after the self-test is performed successfully.
Precaution
Accessories must be connected to the proper receptacle type. In particular, bipolar accessories
must be connected to the Bipolar receptacle only. Improper connection may result in inadvertent
generator activation or a REM Contact Quality Monitor alarm.

Electric Shock Hazard
• Do not connect wet accessories to the generator.
• Ensure that all accessories and adapters are correctly connected and that no metal is exposed.
Use only a Valleylab monopolar footswitch with the Force FX-8CAS generator. Use of an
incompatible footswitch may cause unexpected output.
The instrument receptacles on this generator are designed to accept only one instrument at a
time. Do not attempt to connect more than one instrument at a time into a given receptacle.
Doing so will cause simultaneous activation of the instruments.

Two generators (and two patient return electrodes) may be used simultaneously on the
same patient, provided the generators are the same type (both are isolated or both are
ground referenced). However, the two generators are not synchronized.
One return electrode frequently acquires a high positive voltage while the other acquires
an opposite negative voltage. When this occurs, the potential voltage difference between
them may cause the current to flow from one patient return electrode to the other. The
current causes no harm if it produces no sparks or high current densities on the patient.
Place each patient return electrode as close as possible to the site of the surgery to be
performed by the generator to which it is connected. Ensure that the two patient return
electrodes do not touch.
CUSA handpiece
with CEM If you choose to use a monopolar
nosecone footswitch, you must use only a
Valleylab monopolar footswitch
and connect it to the Monopolar 1
Footswitch receptacle
When you use the CUSA handpiece with CEM nosecone for ultrasonic electrosurgery,
only Low cut or Desiccate 1 coag are available when you activate the handpiece.
To verify or change the Low cut power setting:
To increase the power, press the yellow up arrow ( Δ ) button. To decrease the power,
press the yellow down arrow ( ∇ ) button. The maximum cut power is 100 W.
To verify or change the Desiccate 1 coag power setting:
To increase the power, press the blue up arrow ( Δ ) button. To decrease the power, press
the blue down arrow ( ∇ ) button. The maximum coag power is 70 W.
Autobipolar Activation
Autobipolar activation allows the surgeon to grasp tissue between the tines of a bipolar
forceps for a preset amount of time before the generator automatically activates. The
generator deactivates when the tissue impedance reaches a certain level.
In Autobipolar mode, the generator continuously monitors the impedance between the
tines of the forceps. The generator output activates when this measured impedance
remains below a predetermined value for a preset amount of time.
The generator delivers output power until the measured impedance reaches a user-
defined limit. In addition, the generator will not deliver output power into impedances
below approximately 20 Ω. This prevents activation if the forceps’ tines touch.
Autobipolar Deactivation
RF activation will continue until the generator senses that its upper impedance limit has
been reached. At this time, RF activation ceases automatically.
Once an autobipolar activation sequence begins (during either delay count down or RF
activation), no other keying inputs are processed until the activation sequence is
completed.
Precaution
In the Autobipolar mode the generator automatically activates any time an impedance (e.g.,
tissue) is sensed in contact with the forceps tines. Extreme care should be taken when using this
mode. Never place the forceps on the patient or hold the forceps by the tines because activation
may occur. Always place forceps in a holster when not in use.

The accuracy of most RF instruments is approximately 1–5% of full scale. Using uncompensated
scope probes causes large errors when measuring high voltage RF waveforms.
Perform the following safety check every six months to verify that the generator is
functioning properly. Record the test results for reference in future tests. If the generator
fails to meet any of the checks, refer to Chapter 6, Troubleshooting.
