1.1 Service Characteristics 1.1.1 Identifying the Boards MyLab’s design is based on the use of modular, functionally isolated printed circuit boards (PCBs) and subassemblies known as Field Replaceable Unit. This modularization greatly simplifies on-site service and repair. In most cases, on-site maintenance is accomplished by removing and replacing the PCBs or subassemblies. Most boards of MyLab are identified: • By its Description and reference, which is always indicated on the label. • By the Serial Number (SN), indicated on the label. • By the Configuration Index (CI), indicated by two decimal figures on the label. The Configuration Index represents the HW level of the board. The Configuration Index is loaded in specific components mounted on each board.

1.1.2 Fuses WARNING Do not replace the system fuses with types different from those specified.

1.2 Equipment In this section the required tools to access the system internal parts are listed together with the tools to activate the Service procedures and to perform a functional test of the unit. 1.2.1 Disassembling Equipment The disassembling procedures are described in detail in Chapter 3, UNIT DISASSEMBLY on page 12. Tool Dynamometric Phillips electric screwdriver Short Philips screwdriver Flat screwdriver Box wrench Allen screwdriver Socket Wrench Tweezer Point pliers

1.2.2 Service Procedures USB Service key P/N 140009500 The service procedures that require an interaction with the unit, can be activated through the service key only. The service key must be inserted in one of USB ports. The key must be inserted before switching on the unit, to be able to access to the several service menus. If the procedure is not carried out properly, the system doesn’t allow the access to the menu.

This symbol is used in this manual to indicate all the procedures that require the use of the service key. 1.2.3 USB Medium and Re-Writable CD/DVD To perform a complete check of the unit, it is suggested to always have an USB medium and a re-writable CD/DVD. These tools allow the service technician to test the functioning of the USB ports and DVD burner. 1.2.4 Upgrading File It is suggested to always have the latest revision of the unit upgrading file, together with the pertaining upgrading instructions. These tools allow the service technician to install the software on the unit, should it be necessary. 1.2.5 Safety Test Equipment The safety test must be performed whenever the system composition has been changed, either by adding a new peripheral or by having replaced parts. Refer to chapter 7, SAFETY TEST page 79 in this manual for detailed information on when to perform the tests and how to carry it out.

1.3 Warnings and Precautions WARNINGS It is forbidden to edit or delete files that belong to the software package. Doing so may compromise the system safety. PRECAUTIONS A series of precautions that must be observed each time you perform an operation on the system are emphasized below: • • •

The equipment must always be switched off before carrying out any service operation. In the same way, all the probes and peripherals (for example external monitor, printer, and video-recorder) must also be disconnected. Power off the equipment prior to perform any disassembling operation. An electrostatic discharge occurring through the contact with the operator, can irreparably damage the electronic components on system boards that are sensitive to electro-static discharges: it is therefore recommended that precautions to prevent these discharges are taken each time a board has to be removed/installed. In operational terms, this means: o The machine must rest on an electro-static mat connected to earth. o The service technician must also be connected to the same earth each time he removes or installs the parts. o The boards and components must always be moved in their special electro-static containers. o For the service on the field, use the specific kits including the anti-static mat. o The chapter entitled “system Parts List” details the sub-assemblies that are to be considered sensitive to electro-static discharges (ESD).

When the board is ESD sensitive, you can find this symbol on the PCB master.

REFERENCE: IEC 61340-5-1 (2007)

Probe Adapter Board The Probe Adapter Board is the board for the connection of the echo probes: the probes are physically connected to this board. The board mounts 3 (three) small connectors and 1 large connector, together with the switching logic to enable the active connector. The main function of the board is to switch among the three probe connectors selecting the active one for the acquisition.

Front End Board The Front End Board carries out some fundamental functions regarding probe managing and power supplying. Probe Transmission Section (Tx) The board manages the transmission to the probe controlling the pulses to be transmitted to the elements. The transmitters are individually controlled in terms of enabling, delaying and pulse shape by a dedicated FPGA. Probe Reception Section (Rx) The board manages also the reception of the signals implementing the receiving beam former. The received signals are summed together, amplified, digitally converted and then sent to the dedicated Rx FPGAs that implement the digital focalization. CW Acquisition Section This dedicated section manages the acquisition of the CW signals from their analogic delay to their A/D conversion. Power Supply Section The FE implements the power supply function distributing the supply voltage within both FE and BE boards so that all the other needed supply voltages can be generated. It supplies also the high voltages for probe transmission and the standby voltages for PC module. In this section a dedicated micro-controller manages the system start-up, shutdown, the batteries and their chargers. The micro-controller also monitors the internal temperature and controls the fans speed.

350032600_03

Battery Bridge Board The Battery Bridge board connects the two optional batteries to the Front End. The bridge includes the power voltages, the SMB logic connections and the monitoring thermal signals. Back End Board The board implements several functions. The BE board processes the RF signal through a FPGA and n.2 (two) DSPs. The FPGA processes the RF signal and the Doppler data. The first DSP controls the processes on the FPGA, the acquisition sequences and processes both Doppler data and Physio signal. The second filters and mixes the image data. The PC module is mounted on the BE board. The PC main functions are: • • • • • • • • • •

Processing CFM data Managing of the cine memory, Managing of the scan converter, Generation of signals for the two LCD displays (main display and touchscreen display), Managing of the user interface in terms of input from the keyboard and output to the displays. Managing of the digital peripheral on the USB, Managing of the LAN connection, Managing of the audio signal for the speakers, Control of the Hard disk mounted on this board, Control of the DVD burner.

A dedicated Wi-Fi module is accommodated on the board. This module is connected to the PC Module and to the Wi-Fi antennas. The BE Board also processes the ECG PHISYIO analog signal. Mains Power Group The group manages the connection to the mains power line. It sends and receives power to/from the insulating transformer. It mounts the power sockets for the peripheral devices. An AC/DC module converts the mains voltage to 19V. This voltage powers the electronics and is sent to the Front End. There is also an AC/DC module that generates the supply voltage for the main monitor.
