5. Unit self test.

The self test checks proper functioning of the product, especially the safety circuits, and is activated every time the unit is switched on. The tests are performed by the main microcontroller in combination with the safety micro-controller and take approximately 12 seconds.

When one or both of the controllers detect an error, the output will be disabled. A message will be shown to the user.

The Phyaction series have a safety relay (RLY209). This relay (Normally Open) is integrated in the applied part of channel A and Channel B (same relay). In case of a problem, the safety relay will be switched off immediately and the patient becomes disconnected from the unit.

The safety relay driver circuitry is accessible to the main microprocessor for 3 seconds after power up of the unit. After this period the main micro-controller will not be able to switch the electrotherapy safety relay on any more. Both the main and the safety micro-controller are able to switch the electrotherapy safety relay off (the safe state).

During the selftest of the unit, the following items are checked:

1. Main controller test.

2. Safety controller test.

3. Safety software test.

4. Electrotherapy DAC test Channel A

5. Electrotherapy DAC test Channel B

6. Electrotherapy relay test.

7. Electrotherapy safety comparator test.

8. AC/DC relay test.

6.2 Power supply

A Switch Mode Power Supply supplies the PCB with +15V, +5V and –15V. U114 regulates the –15V down to a –5V supply.

Circuit around U119 is a square wave oscillator that generates a square wave with a maximum voltage of 0V and a minimum of –15V. Following is a voltage doubler that converts the –15V to –30V that is then regulated up to –22V by the zener D113 for the LCD contrast.

6.3 User interface board (UI)

The user interface boar is a separate board for the Phyaction U. For the Phyaction E/I/C it is mechanically linked to the electrotherapy board.

6.3.1 Microprocessor circuits.

U103 is the micro controller. U109, U110, U115 and U116 are static RAM’s. U109 and U110 are 32k Ram’s and U115 and U116 are 128k Ram’s. Only one sort is placed, the 32k’s or the 128k’s depending on how much memory is needed. IC’s U101 and U102 are Flash Memories that contain the software. All these devices are addressed by the address bus CA[0:23] and the data is transported over the data bus DQ[0:15].

Phyaction U/E/I/C – service manual version 0.1 Page 9

6.3.2 Display and keyboard circuits.

U123 is the LCD display driver with its own RAM’s namely U111 and U112. They are addressed via VA[0:15] and the data is transported over data bus VD[0:15].

Besides controlling the safety circuits (described further on) the “safety” µprocessor U122 does the scanning of the keyboard and of the two encoders.

The four ENC pins on port B scan the two encoders. The four KEY_SCAN pins of port B are used to select the scan lines of the keyboard. KEY_CLK provides the clock on which the keyboard will be scanned and KEYB_INPUT receives the serial information from the key scan.

6.4 Electro stimulation PCB

This board is mechanically connected to the user interface board and is installed only in Phyaction C/E/I.

6.4.1 Amplitude generation and signal processing

The amplitude and signal generation is fully done with D/A converters. U214 is a quadruple 8-bit D/A converter with each DAC having its own reference input. Each electrotherapy channel uses two of these DACs in series. The first DAC the Amplitude DAC has a reference of 2,5 V. This DAC is used too set the Amplitude of the signal. Its output is used as reference for the second DAC the LFDAC. This DAC modulates its input and therefore can generate the waveforms such as triangular or sinusoidal  DAC_A/B. The circuit around Op-Amp U231 inverts the signals DAC_A/B  IPAA/B

Via the analogue multiplexer U204 a couple of signals from the ET stage can be fed back to the ADC input of the micro controller U103 so these can be monitored.

6.4.2 Output circuits

Output circuit A and B are identical, therefore only output circuit A is explained. The ET power stage has only one configuration in contrary to the 500/800 hardware namely constant current.

At the middle connection of the transformer is the +15V supply voltage connected. The two other sides of the primary windings are connected to the drains Q206.The gates of Q206 are connected to NEG_A and POS_A. These are the “chopper” FETs. The sources of Q206 are coupled together and are connected to the drain of Q208 that is the current regulator MOSFET. The circuit round Op-Amp U221 and MOSFET Q208 controls the current. The circuit forces a voltage across current sense resistor R201 by controlling the gate-source voltage of Q208. IPAA is a measure for this voltage across or the current through R201 and so the output current.

By making POS_A or NEG_A high one side or the other of the transformer will conduct a current and so on the secondary side of the transformer “positive” or “negative” pulses are generated.

This can also be done in a constant stream of pulses (f=10kHz), which then generates a biphasic rectangular pulse train at the output.

By varying or modulating IPAA the amplitude and waveform of the output signal is set.

Constant voltage mode: The hardware has no real constant voltage mode. Instead a 1kΩ resistor is switched parallel to the current source. By applying the theorem of Thévenin you get a non-ideal voltage source with an impedance of 1kΩ. This results in a behaviour that is close enough to a real constant voltage  no large increase of output voltage when there is no load at the output.

At the secondary side there are some relays with which the rectifying or combination path can be selected or polarity can be changed.

Phyaction U/E/I/C – service manual version 0.1 Page 11

6.4.3 Poor contact detection

Poor contact detection is done with an opto-coupler U216 in the secondary/patient circuit. When a current flows through a load/patient the output of U216 will go “low”. When no current flows through a load (no load  poor contact) the output will go “high”. Comparator U231 sees to it that no poor contact can be detected when the amplitude is very low (<10mA). Because opto coupler doesn’t function properly at low amplitudes. Only when there is a POS or a NEG signal there can be output. So only then poor contact detection should work. Poor contact if: output opto coupler is high AND when POS or NEG is high AND Amplitude>10mA

6.4.4 Current measuring circuits

The output current is measured at the primary side with a high side current sense amplifier U212. It measures the voltage over a sense resistor of 80mΩ R320 and outputs a current equivalent to the current through this sense resistor. The output current is turned into a voltage by the output resistor so the voltage over R216 is a measure for the output current. All component values are chosen so that at maximum allowable output current +10% (=120mA+10%=132mA) the output voltage of the current measuring is

2.5V At poor contact the output of the current sense amplifier is shorted to ground with a MOSFET. The circuit around Op-Amp U202 and analogue switch U205 is a hold-circuit. So that at non-continuous currents and/or AC currents the peak levels are holded.

6.4.5 Safety control circuits

The safety control module is built round µProcessor U122. The safety relay is driven by a RS flip-flop which is build with one NOR and two NAND’s (U219 and U208).

In case of an error detection by one of the micro controllers, the Microchip (U122) can switch off the safety relay by making MC_SRY_OFF, “high”. The Siemens µController (U103) can switch off the safety relay by making S_SRY_OFF, “high”.

A “high” level on MC_SRY_OFF or S_SRY_OFF-line will bring the “SET” input of the flip-flop ‘low’. The output state of the flip-flop becomes “low”. The safety relay is switched off.

The “SET” input can also be “low” when the UVLO (under voltage lockout) or POR (power on reset) signals are “low”.

Note that even when error is not longer occurring, the output state of the RS-flipflop stays “low”. The safety relay stays switched off.

In normal operation TIMELOCK is “high”. When the safety relay is switched off, then the safety relay cannot be switched on again. The only way to reactivate the safety relay is to switch off and on the power.

When the TIMELOCK signal is “low”, a reset of the RS flip-flop is done. The outputstate of the flip-flop becomes “high”. Safety relay is switched on. The output state remains as long as no “low” signal is available on the “SET”-input of the flip-flop.

Only during initialisation (self-test) TIMELOCK is low, so then the state of the safety relay is equal to (MC_SRY_OFF NOR S_SRY_OFF) NAND !PROTECTION.

Phyaction U/E/I/C – service manual version 0.1 Page 12

Comparator U218 and DAC U206 guard the output level. U218 compares the output signals from the current measuring circuit CUR_A_SAF/CUR_B_SAF with FDBACK_SAFA/FDBACK_SAFB reference voltages. These reference voltages are generated by the safety DAC U206 and are set up by the µProcessor U122 via bus MC_DATA[0:7]. The levels of these voltages (0,284V-2,5V // 15mA-132mA) are a measure for the output current and are adjusted when the intensity of the ET output is altered by the user. U209 serves as a buffer for the FDBACK_SAFA/FDBACK_SAFB signals. If these signals are exceeded by CUR_A_SAF and/or CUR_B_SAF then !PROTECTION will go “low”. This will change the state of the flip-flop from “high” to “low” so the safety relay RLY209 will be switched off.

The ET_ERROR-line is “low” when the safety relay is on. The ET_ERROR-line is monitored by U103 and U122.

All these situations described above are only valid if CON202 is in OPERATE mode and CON9 has no jumper. When CON202 is in service mode then the relay stays switched on even when error occurs. The error information is now directly linked with the ET_ERROR line. If CON108s a jumper then the safety relay can be switched on/off at all time because TIMELOCK will be “low” at all time.

6.4.6 Relay circuits

IC U224 is a Darlington transistor array which makes it possible to drive the relays with the low power signals from the µC. Diodes for inductive load suppression are integrated in this IC.

7. Ultrasound heads

The Phyaction U and Phyaction C can be delivered with 2 different multifrequent ultrasound heads:

Model U91 : 1 cm² 1/3 MHz Model U92 : 4 cm² 1/3 MHz

(See technical specifications for more details)

The unit has two ultrasound output connectors.

The ultrasound head converts the electric signal into ultrasound using a piezo crystal. This crystal, with a diameter depending on the desired head size, is glued in an aluminium cup that minimises electromagnetic radiation and enables the crystal to be used on to operating frequencies. The aluminium cup can also be used as a second electrode if combination therapy is desired. A separate electrotherapy device needs to be connected to the safety socket for combination therapy. An OTP is installed in the connector of the treatment head to enable the micro controller to detect whether a head is connected and to recognise the type of head that is connected. It also contains the calibration values of the head in question.

The ultrasound head has an auditif and visual contact control indication: the treatment heads are fitted with light of two colours, yellow and green. The following configurations are possible:

Blinking green: The US head is properly connected Continuous green: The US head is selected Continuous yellow: The US-emission is in progress Alternating yellow/green: Bad contact of the US head with the skin Blinking yellow: End of treatment

Phyaction U/E/I/C – service manual version 0.1 Page 14

7.1 Contact control indication

Depending on the contact between the US head and the patient, the display has the following possible indications:

Phyaction U/E/I/C – service manual version 0.1 Page 15

8. Yearly safety inspection

The ‘Directive on Medical Devices’ from the European Commission (92/42/EEG) requires that safe devices are used. It is recommended to perform a yearly technical safety inspection. If the legislation in your country or your insurer prescribes a shorter period, you must adhere to this shorter period.

On the following pages the format of the yearly checkup is printed. Fill out this document for each test.

In order to perform this test, the following devices are needed:

- Digital Ultrasound power meter

- Oscilloscope 20 MHz at least

- 500 Ohm power resistor

- Electrical safety tester (according to IEC or VDE)

9.3 Cable test (9).

Important: a cable test can only be performed through channel A.

Select ‘cable test’ in the system settings menu.

Connect the patient cable to the channel A (without the plate electrodes) and make a shortcircuit with the supplied connector (red female-female connector)

Turn up the intensity to 10 V and move with the plugs and cable to detect a bad contact. The unit will now display whether the cable is ‘ok’ or ‘bad’.

Perform the same test for the other patient cables.

9.4 Error History(11).

This menu will give detailed information of the last 10 errors that have been occurred. This is an important tool to detect a problem, especially when it concerns intermittent errors. In this menu it is not possible to make a reset of the error message (since this is accessible for the customer: chapter service menus)

Phyaction U/E/I/C – service manual version 0.1 Page 24

9.5 Counter working hours.

This menu gives an overview of the working hours per module (ET, US) and per channel. It can help a service engineer to justify for example a worn-out ultrasound cable.

9.6 Reset menu

The reset menu offers the possibility to reset

1. The working hours for each single module.

2. Restore programs to the original configuration or save a new setting (not for advised programs)

10.4 Reset menu

10.4.1 Reset error history

By pressing this key twice, the error history will be restored.

10.4.2 Total reset settings.

By pressing this key twice, a total reset of the machine is executed.

The total reset settings menu makes a reset off ALL the previous settings and information (like working hours and error history)

Since some boards are being used in several machines, we have an auto detection system. If we provide a main board, we have done a total reset of all settings. When the board is replaced and the machine is switched on for the first time, the screen below appears: ( example below of the Phyaction U)

GYMNA-UNIPHY PRODUCT INFORMATION

Determined type: Phyaction C

Press ‘back’ to confirm or any other key to reject

Check whether the determined type in correct and confirm with the go back key.

/ Every main PCB that GymnaUniphy provides, had a ‘total reset’ of it’s parameters. It is normal that the screen above appears when the unit is switched on for the first time

Now the following screen appears:

Phyaction U/E/I/C – service manual version 0.1 Page 31

Now all the hardware codes of the boards have to be introduced in the service menu (Chapter

10.1). Therefore the unit needs to be opened. Each board carries a label with the hardware code.

/ This can only be done by a qualified service engineer.

Press the ‘go back’ key after all the data is correct. Now the system settings menu appears. Change the settings if required. Now perform a complete check-up of the machine.

Phyaction U/E/I/C – service manual version 0.1 Page 32

11. Upgrading system software.

11.1 General information.

The software of the Phyaction series can easily be updated. There is a flash memory on the main PCB that can be reprogrammed using a special interface tool.

/ The Medical Device Directive does not allow end users to reprogram medical devices. This is only reserved to authorized service personnel.

11.2 Which tools are required ?

A PC with Windows 98/98SE/Millenium/NT/XP, CD-rom drive and a free COM/USB port. The file with the software to be programmed (provided on CD rom) An USB to RS232 converter when the PC has no RS232 output connector. A special interface cable (photo below) ordering ref 117.135 A RS232 transceiver (photo below) ordering ref 117.006

Phyaction U/E/I/C – service manual version 0.1 Page 35

/ The unit now displays the message: STATE: CONNECTED

: Click next and in the list ‘available flash profiles’ select ‘ALL 200’ and click ‘Next’

Step 9

Step 10

: The flash procedure must now start. The following screen appears:

This will take about 7 minutes. When the flashing is finished, click on the button ‘NEXT’. The following screen must appear:

Phyaction U/E/I/C – service manual version 0.1 Page 36

If the flashing was terminated successfully, switch off the unit . Now close the program, remove the flash cable and install the rubber foot. Switch on the unit. The new software is now installed.

/ Check the software version in the start-up screen.

11.4 Troubles with flashing.

If the PC cannot connect to the unit, check whether the interface cable is properly connected and check whether the right COM port has been chosen.

Phyaction U/E/I/C – service manual version 0.1 Page 37

12. Hardware labels.

Each PCB (except the display PCB and the power supply) has 2 labels, one with the hardware code and one with the serial number.

12.1 Label with hardware code and ref number.

The main PCB has an eeprom in which the actual hardware code of the used PCB is saved.

The hardware code consists of 4 characters and is composed as follows (from left to right):

0…

.A..

..A.

…A

Example:

Suppose that resistor R68 changes from 22 K to 100 K. The actual hardware version 1AAA will be upgraded to 1ABA.

From 1 to 9. Increase in case of a

principle technology change.

A to Z Increase in case of a

principle technology change.

A to Z Increase in case of

component change.

A to Z Increase in case of a PCB

track change.

Hardware is not compatible anymore. All previous changes made in hardware shall be inherited in the new layout. The last 3 alphanumerical numbers will begin with A Components are not anymore compatible with the previous layout. All previous changes made in hardware shall be inherited in the new layout. The last 2 alphanumerical numbers will begin with A

Phyaction U/E/I/C – service manual version 0.1 Page 38

12.2 Upgrading the hardware code.

Every hard-or software change will be presented in a technical bulletin. In case of a hardware change GymnaUniphy will provide the necessary components as well as a new hardware label. This label must be put on the upgraded PCB.

The hardware code also has to be modified in the serial eeprom. See chapter 10.1 for more details.

/ The user can easily see the hardware code of each PCB in the system settings menu.

12.3 Label with serial number

Critical parts must be traceable meaning it must be identifiable at least on lot level for source and destination. To end this, critical parts must be labeled.

Phyaction U/E/I/C – service manual version 0.1 Page 39

13. Troubleshooting.

13.1 General information.

In case of a problem the unit will produce an error code. Intermittent error codes can be recovered by means of the service software, which gives an overview of the last 10 error codes.

13.2 Skipping the self test

When the error code is generated during the self test, and the cause of the problem is difficult to detect, there is a possibility to skip the self test.

When starting up the machine, press the function keys F1 and F7 at the same time. The self test will now be skipped.

13.3 De-activate the safety relay (only for Phyaction I/E/C)

In order to deactivate the control of the safety relay, the position of the jumper ‘operate/service, located on the ET board, must be put from position ‘OPERATE’ to position ‘SERVICE’. Putting the jumpers into ‘SERVICE’ position will avoid that the safety relay can be switched off.

Since the functioning of the safety relay is tested during the selftest, it will generate an error code when the unit is in ‘SERVICE’ mode. Therefore the selftest must be bypassed (13.2: skip of self test)

After both the ‘SERVICE’ jumper and the factory jumper are changed, the unit can be powered up without performing a selftest and without the possibility to deactivate the safety relay.

/ It is very important that after repairing the unit, the unit will be reset to ‘OPERATE’ Not following this instruction can bring the safety of the patient and the therapist in jeopardy.

In case the service engineer cannot solve the problem, it is recommended to communicate the problem with the GymnaUniphy service department.

Phyaction U/E/I/C – service manual version 0.1 Page 40

13.4 Interpreting error codes.

In case of an error, the following screen appears:

The unit gives an overview of the actual error. The error code can be traced in the error list (chapter 12).

Different codes:

Error number: defines the software module in which the error is detected. Error value 1: the first error value which defines the individual test in the module which

actually generated the error

Error value 1: an additional value which may give more information about the detected error. Error value 2: (not used).

Phyaction U/E/I/C – service manual version 0.1 Page 41

13.5 List of error codes.

This chapter defines the individual error numbers. Each error number is related to a software module. For each error number the code used in the software is defined, the number is defined and a short description about the purpose of the software module is given.

13.6 Error groups

14. Replacement procedures.

The most frequent service operations will be exchanging defective boards rather than repairing them.

When handling static sensitive devices such as PC boards of the Phyaction, the following precautions should be observed:

- Persons should be earthed by means of a wrist strap.

- Ground all electrical equipment, work bench, soldering iron…

Depending on the type of machine, different PCB’s are installed. This chapter explains the assemble and disassemble procedures for the Phyaction C that has all of the different boards inside.

+ After the machine has been opened for any reason, perform a complete test as prescribed in chapter

14.1 Disassemble instructions

14.1.1 Opening the unit and removing the top cover.

Step 1: switch of the unit and remove the 3 screws on the rear side. Step2: remove the 3 screws on the bottom front side of the unit. Step3: put the machine on a table and smoothly lift up the rear side of the top cover Step4: unplug the 2 ultrasound connectors on the ultrasound PCB that is installed under the

top cover and unplug the interface cable between the UI board and the Ultrasound board. Step5: unplug the white flatwire cable of the display (open the white connector by sliding it to the front)

Step6: unplug the backlight connector the encoder cables and the power led cable Step7: unplug the flatwire of the keyboard. The top cover can now be removed.

14.1.2 Removing the main PCB.

Step 1: open the unit as explained in 14.1.1 Step 2: pull out the connector between the main PCB and the power supply board. Step 3: pull out the cable to the fan Step 4: unscrew the metal plate that secures the ET output connectors (not for Phyaction U) Step 5: unscrew the 9 screws that fix the board and remove it (4 screws for Phyaction U)

14.1.3 Removing the power supply board

Step 1: open the unit as explained in 14.1.1 Step 2: unplug the mains connector and the connector to the main board Step 3: remove the 2 screws on the left side of the board and unlock the 2 black supports on

the right side (don’t damage any components on the board !) and take out the board.

14.1.4 Removing the ultrasound board

Step 1: open the unit as explained in 14.1.1 Step 2: remove the 4 screws of the board and unlock the 2 black supports on the right side

(don’t damage any components on the board !) and take out the board.

Phyaction U/E/I/C – service manual version 0.1 Page 52

14.1.5 Removing the display PCB and/or keyboard

Step 1: open the unit as explained in 14.1.1 and put the top cover on a table. Step 2: pull off the black knob(s) of the intensity rotary Step 3: turn the cover, remove all the screws of the rotary’s and power LED and take them out Step 4: remove the 4 nuts (M5) of the metal cover and gently remove the metal cover by

removing the cables that feed through the metal cover Step 5: remove the display board by removing the 4 screws that secure it or remove the keyboard by pulling it out of the plastic top cover (photo 1)

14.2 Assembly instructions

14.2.1 Installing the display PCB and/or keyboard

Follow the steps as explained in 14.1.5 in reverse order. Especially pay attention to the following points:

- A new display might have a protecting film. Remove it first

- Make sure that the display and the screen is 100% clean before assembling it.

- Don’t forget to put the plastic washers on the 4 screws of the display boards

- Only use the self securing nuts to fix the metal cover

- Make sure that all the cables that are feed through the metal cover are free and show not any damage (photo 2 )

- Make sure that the rotary encoders and the power led PCB are fitted in a way that the cable connections are face to face !!!

- After installation check whether the power LED is exactly behind the window in the front.

14.2.5 Closing the unit and installation of the top cover.

Follow the steps as explained in 14.1.1 in reverse order. Especially pay attention to the following points:

- On each connector of the main board there is an indication of the use of the connector. Make sure that connectors are not mixed.

- The cables of the Ultrasound output have to be fit UNDER the interface cable of the ultrasound board

- When closing the cover, make sure that the cover fits onto the bottom without pushing it. If this is necessary, check the wires for proper installation.
