Chapter 5 “List of Replaceable Parts” contains a complete list of part numbers with descriptions and associated illustrations to help locate each part. Chapter 6 “Schematics” contain the schematics of the Analyzer.

Safety Information In this manual, a Warning identifies hazardous conditions and actions that could cause bodily harm or death. A Caution identifies conditions and actions that could damage the Analyzer, the equipment under test, or cause permanent loss of data.

XW Warning To avoid possible electrical shock or personal injury, follow these guidelines:

1-4

•

Use this Analyzer only in the manner specified by the manufacturer or the protection provided may be impaired.

•

Read the Users Manual before operating the Analyzer.

•

Do not connect the Analyzer to a patient or equipment connected to a patient. The Analyzer is intended for equipment evaluation only and should never be used in diagnostics, treatment or in any other capacity where the Analyzer would come in contact with a patient.

•

Do not use the product in wet or damp locations, around explosive gases or dust.

•

Inspect the Analyzer before using it. Do not use the Analyzer if abnormal conditions of any sort are noted (such as a faulty display, broken case, etc.)

•

Inspect the test leads for damaged insulation or exposed metal. Check test lead continuity. Replace damaged leads before using the Analyzer.

•

When testing, always be sure to keep your fingers behind the safety barriers on the test leads.

•

Never open the Analyzer's case. Dangerous voltages are present. There are no user replaceable parts in the Analyzer.

•

Have the Analyzer serviced only by qualified personnel.

•

The Analyzer must be properly earthed. Only use a supply socket that has a protective earth contact. If there is any doubt as to the effectiveness of the supply socket earth, do not connect the Analyzer. Do not use a two-conductor adapter or extension cord; this will break the protective ground connection.

•

Do not use the 15-20 A adapter to power devices rated in excess of 15 A. Doing so may overload the installation.

Introduction and Specifications Specifications

•

Use extreme caution when working with voltages above 30 V.

•

Use the proper terminals, functions and ranges for the test being performed.

•

Do not touch metal parts of the device under test (DUT) during analysis. The DUT should be considered an electrical shock hazard when connected to the Analyzer as some tests involve high voltages, high currents, and/or the removal of DUT earth bond.

Introduction WX Warning To avoid electric shock, personal injury, or death, use extreme caution when servicing the Analyzer. The Analyzer can generate high voltages and currents. The Analyzer tests electrical safety of medical equipment by making the following measurements: •

Resistance from the case of the instrument under test case to the power cord earth connection.

•

Leakage current to the case of the instrument under test. This and all other leakage currents are measured across one of two standardized patient loads that simulate a human body

•

Leakage current to earth

•

Leakage current to patient electrical connections

•

Leakage current to patient electrical connections when mains voltage is applied to the connections

•

Insulation resistance from mains supply to various instrument under test points

•

Although not a measure of electrical safety, mains voltage and equipment current are also measured

These tests are preformed in various configurations as specified by different regulatory agencies. See the ESA612 Users Manual for more information of the agency standards.

Block Diagram Description The Block Diagram shown in Figure 2-1 shows the two printed circuit assemblies (PCAs) and the interconnection between them and the Analyzer connections. A unique number in the upper-left corner of each block in the diagram references the Analyzer assemblies as follows: C = Chassis, P = A1 Power pca, M = A2 Meter and User Interface (Meter) pca. These numbers do not directly correlate to reference designators on the schematics. A1 Power PCA The mains connection is supplied through the Power Entry Module (C5), a 14-gauge cable (C4), a connector (P23), and the fuses (P16). The main power supply is a switching power supply module (P13). It is powered directly from mains power and operates from 90 to 264 V ac. The Analyzer has two circuit sections galvanically isolated from each other; one is earth referenced and is used mainly for the Equipment Outlet circuitry, and the other is used for the Meter circuits. The Earthed +12 V Supply [P13] drives the Isolated ±5 V Regulator (Reg) (P8), the Isolated +3.3 V Reg (P9), the Earthed +3.3 V Reg (P10) and is routed to the Meter PCA at connector (P1). The Isolated ±5 V Reg (P8) supplies power to the 250/500 V Reg (P3) and the 0.2 A Current Source (P4). The 250/500 V Reg is used for insulation resistance tests, which are measured by placing the voltage across the device and measuring the resultant current to calculate the resistance in the range of 0.5 - 100.0 MΩ. The 0.2 A is used for low resistance tests. The current is routed through the device to be measured and the resultant voltage is measured and used to calculate the resistance in the range of 0.0 – 2.0 Ω. The Mains on applied part transformer (P14, MAP XFORMER) has a 1:1 ratio to generate an isolated mains voltage. MAP Current Limit (P11) sets the MAP current limit to 1 mA, 3.5 mA, or 7.5 mA for the various regulatory standards. 2-3

ESA612 Service Manual

The Mains Meter (P15) attenuates mains voltage, measures it, and converts it to digital format. The digital signal is routed to the meter microprocessor (M19) on the A1 Meter pca through The Digital Isolator (P12) which provides galvanic isolation between the mains attenuator and the meter. The Test Setup Relays (P5) connect the various current sources and voltages for different test setups. The relays are controlled by relay drivers (P6), which are isolated by the digital isolators (P7). The Equipment Outlet (C7) is connected to the A1 Power pca through a 14-gauge cable (C6) and a connector (P24). Power relays are used to control the configuration of the Equipment Relay. Reverse Relays (P20) are for reversing hot and neutral. On/Off Relays (C19) are for opening hot, neutral or earth. There is a solid-state relay (P18), which is turned off before changing the state of the other equipment outlet relays and then turned on again to prevent arcing on loaded relays. The other set of reverse relays (P17) are used to reverse the polarity of incoming power if the Analyzer senses mains are reversed at the main input, thus providing extra relay protection by insuring that hot is routed through the solid state relay. Two feed-through transformers are connected in front of the equipment outlet to monitor current drawn by the device under test. The Differential Current Transformer (P22, DIFF CUR XFORMER) monitors the difference in current between hot and neutral for the differential current test and for ground fault current detection. These signals are routed to the test setup relays (P5). There are two cables between the two pcas, a 24-gauge cable (C2) between the connector (P1) and the connector (M34) for power signals and a Ribbon Cable (C3) connected between connector (P2) connector (M35) for digital signals. A2 Meter and User Interface PCA Power for the A2 Meter and User Interface (Meter and U/I, or Meter) PCA is supplied by U/I Supplies (M22) and Meter Supplies (M23). These are powered from the Earthed +12 V Supply (P13) on the A1 Power PCA. The U/I microprocessor (M14) operates the various user interface components. It writes to the display driver (M9) which controls the display (C1) through connector (M7). The display contrast is set by display contrast (M10). The U/I microprocessor reads the keys (M1) and sets the warning LED (M2). In addition, it controls the Audio Indicator (M8). It communicates with the meter microprocessor (M19) using an RS232 format through the digital isolators (M18). The U/I microprocessor also communicates with the port using an RS232 format through the digital isolators (M15) and the RS232 to USB converter (M11). The meter microprocessor (M19) sets up tests by controlling all the relay drivers on both pcas (M17, M20, P6). The measured signal comes from several places: the meter jacks (M5), applied parts (AP) jacks (M4), and the equipment outlet (C7). These are routed through the test setup relays (M21) to the patient load (M32) and then to the buffer amplifier (M30, BUFFER AMP). The signal is then separated by the AC Only Filter (M26) and the dc Only Filter (M29). The ac signal is converted to a dc voltage proportional to the rms value by rms converter (M25) and converted to digital format by the multi-channel analog-to-digital converter (ADC) (M24). The meter microprocessor (M19) reads the ADC (M24), formats it for the specific measurement being taken, and sends it to the U/I microprocessor (M14). The BUFFER AMP (M30) is protected by the over-voltage detect (M31) which can open all relays through relay driver disable (M28). The ground Fault Detect (M33, GFI) receives a signal from the DIFF CUR XFORMER (P22) on the A1 Power PCA, and if the signal is over the programmable threshold, it shuts down the relays through the relay driver disable (M28). 2-4

The AP jacks (M4) are connected in various combinations to measurement circuit points depending on the test being performed. This is done by the relays (M13) and relay drivers (M17). The ECG waveform from the meter microprocessor (M19) is buffered and amplified by the ECG amplifier (M16, ECG AMP) and attenuated to the low voltages required for the ECG signals by the ECG Attenuator (M12, ECG ATTEN). The null jack (M6) is connected only during the ground resistance check and is used to zero out the resistance of the test leads.

Detailed Circuit Description The following section describes the operation of the Analyzer circuits. A1 Power PCA The A1 Power PCA contains the power supplies, transformers, power relays, Equipment Outlet, and some of the test selection relays. Equipment Outlet Relays The circuitry along the top of the schematic on sheet 1 of the A1 Power PCA schematic controls the Equipment Outlet (EO). Mains is connected to the pca at J5. The EO is protected by fuses F1 and F2. Relays K1 and K2 reverse the polarity of mains in the event it is reversed at the input. Following this is a solid state relay, K19. This is turned off when any of the mechanical relays controlling the EO are switched, and then it is turned on again. This protects the mechanical relays from damage caused by inductive or incandescent loads or shorts. In the case of an EO short, the solid state relay can pass up to 900 amps for the time it takes the fuses (F1 and F2) to open. Relay K3 shorts out the solid state relay after all relay switching is done to keep power dissipation low. Relays K4 and K5 turn on the EO. Relays K6 and K7 reverse the polarity. EO ground is opened by relay K11. Relay K12 connects the resistance measuring, current source return to the EO ground pin for earth resistance tests. Relay K14 connects the EO ground pin to the meter for earth leakage tests. Relay K8 connects the EO hot and neutral pins together for leakage and insulation resistance tests. Relays K9 and K10 connect the shorted EO hot and neutral pins to the meter, 500 V or the MAP voltage as required. Equipment Outlet Current Measurements Transformer L1 is a differential transformer with hot and neutral running through it. The difference in current between these is detected by the transformer. U1 converts the current to a voltage that is used for differential leakage measurements. This is selected for measurement by connecting it to PWR_GRP by closing U8 pins 14 and 15. The output of U1 is also connected to GFI_SENSE for measurement by the GFI Detect circuit on the A2 Meter PCA. Transformer L3 is a current transformer that monitors the EO current for the equipment current measurement. This is selected for measurement by U8 pins 2 and 3. Mains Measurement Hot is routed through fuse F3 to protect the Analyzer’s internal circuitry from excessive current. Mains voltages are measured and used to detect open ground, reverse polarity, and out of range conditions. Resistors R2, R3, R4, and R17 attenuate the hot to ground voltage and U4B buffers it. The neutral to ground voltage is similarly attenuated by resistors R5, R6, R7, and R18 then buffered by U4A. These analog signals are converted 2-11

ESA612 Service Manual

to digital signals by the two-channel analog to digital converter (U3, ADC). This has a two-wire serial port containing a clock and data line and a third line for chip selection. See page 3 of the A1 Power PCA schematic for further routing of the digital signals to and from the ADC. U7 monitors the hot to ground and neutral to ground signals to generate a mains zero-cross signal used by the meter microprocessor. Isolated Mains Voltage (Mains on Applied Parts or MAP) Transformer T1 is a 1:1 transformer that generates the isolated mains voltage used by many of the Analyzer tests. Transistors Q1 and Q2 form an active current limit circuit. The current limit can be set to 3 different values, 1 mA, 3.5 mA, and 7.5 mA depending on the selected international standard. U10 selects 3.5 mA, U29 selects 7.5 mA. As the current increases, the voltage across the selected resistor increases until it reaches about 7.5 V. At this point, Q2 begins to conduct preventing Q1 from being turned on any further. This clamps the current, but the voltage across Q1 can continue to increase. The bridge CR12-CR15 allows the circuit to operate with both polarities of current. Relay K17 connects the output to the test circuits and relay K16 reverses the polarity of the voltage. Connectors There are two connectors between the A1 Power PCA and the A2 Meter PCA. Jack J2 is a 6-pin 22-guage wire connector for high current signals. Jack J4 is a 20-pin ribbon cable for digital signals and low-current power supplies. Isolation To maintain galvanic isolation between the meter circuits and the earthed circuits, the digital signals are isolated by digital isolators U2 and U5. U2 isolates the relay driver signals and U5 isolates the Mains ADC signals. Optical isolators are used to isolate signals not needing the bandwidth of the digital isolators. U11 isolates the relay driver strobe and U6 isolates the mains zero cross signal. Power for the earthed side of the isolations is from the +3.3V supply U12. Power for the isolated side is from the +3.3V supply U28. Relay Drivers U14 and U16 are serial-in parallel-out shift registers. These have a three-wire serial interface with clock, data, and strobe lines. A fourth line, output enable (/OE), is used to enable or disable all the outputs and thus the relays. The outputs of the shift registers control the relay drivers U13 and U15. Isolated Signals Meter signal lines that control circuits on the isolated side are expanded by shift register U25, like the relay driver shift registers. Power Supplies The main power supply for the Analyzer is U9. This is a switching supply that can be driven from an ac source between 90 – 264 V ac and 50 - 60 Hz. The output is +12 V and is isolated from mains. U18 is an isolated dc to dc converter module with output switching ±5 V dc. It powers the resistance measuring current source and the insulation resistance voltage source. Resistance Current Source Resistance is measured by applying a current to the resistance to be measured and measuring the voltage developed across it. The Analyzer uses a 200 mA ac source. U23 and Q4 form a precision current source. The current is set to 400 mA by the 1 Ω resistance made up of R85, R86, R76, and R59. U23 sets the voltage across the resistors equal to the reference voltage at pin 3. The reference voltage is from U22, a 1.2 V 2-12

reference, divided down to 0.4 V by R77 and R78. Q4 provides the high output impedance needed for a true current source. Isolator U19 is switched on and off to turn the current source on and off to make the 200 mA ac current. Insulation Resistance Test Voltage The 500 V dc voltage source uses a transformer to boost the voltage. A pulse width modulator drives the primary of transformer T2 to set the secondary voltage. CR5 and CR10 rectify the secondary and C29 and C42 filter it, resulting in 500 V dc. The voltage is attenuated to 5 V by resistors R41, R56, R57, and R46. U17 compares this to its 5 V reference voltage and sets the width of the output pulses to maintain the divided voltage at 5 V. The voltage can be set to 250 V by turning off Q5 and turning on Q6. This changes the attenuator such that the output voltage is 250 V. U24 senses the return current to the transformer and shuts off the supply if it exceeds 1.5 mA. Relay K13 connects the supply for tests and when not selected, connects a resistance to ground to discharge capacitance in the device under test, R63 and R64. A2 Meter and User Interface PCA Schematic The A2 Meter and User Interface PCA contains the two microprocessors, the meter circuit, test jacks, keyboard USB port and display driver. Meter Inputs The meter input jacks are P12 and P13. These are connected for various tests by relays. Relay K13 connects the red jack to the patient load for leakage tests. Relay K15 connects the red jack to a voltage attenuator used for the Point to Point voltage. Relay K16 connects the red jack to earth through a current limiter. Relay K19 connects the red jack to the resistance current source. Relay K17 connects the black jack to the negative input of the meter, –Meter (GNDMA). Relay K21 connects the black jack to the resistance current source return. The null post, P24, is connected to –Meter (GNDMA) by relays K17 and K18 for nulling the test lead resistance for earth resistance measurements. Patient Load Leakage currents are measured across the patient load. Resistors R78 and R79 form the 1-kΩ resistance for the input of the AAMI and IEC60601 patient loads. For leakage currents greater than 2 mA, the meter input is switched from resistors R78 and R79 to divide the voltage by five. Resistor R68, capacitor C100, and resistor R156 form the rest of the patient load. Closing U27 pins 14 and 15 forms an AAMI load. Closing U27 pins 10 and 11 forms an IEC60601 load. Closing U27 pints 6 and 7 connects the load to the measurement circuits on page 2 of the meter schematic. With this open and U27 pins 2 and 3 shorted, the differential current and equipment current from the A1 Power PCA are selected. Overvoltage Protection Small over-voltages at the meter inputs are clamped by CR9, VR6, and VR7. Severe over-voltages over about 50 V are sensed through the attenuator U83, R86, and U18. This is routed to schematic page 2. Mains on Applied Parts Compensation The isolated mains voltage (MAP) used in many AP leakage tests causes a residual leakage that must be compensated for. Digital to analog converter (DAC) U21 and amplifier U22 generate an ac voltage waveform that accurately tracks the MAP voltage. This is summed with the meter input leakage current through C76. The digital value set in U21 sets the amplitude of this signal which is adjusted to cancel the residual leakage.

2-13

ESA612 Service Manual

AC Only U54 buffers the signal from the meter input circuitry. In the ac only mode, the signal is routed through U39 pins 10 and 11 to the ranging amplifiers U28 and U26. The gain is selectable to be 0.15, 1.5 or 15 by the state of analog switches U25. This signal is then AC coupled by C77 to the RMS converter U23. This generates a dc voltage equivalent to the rms value of the input signal. U31A forms a two-pole-low-pass filter to smooth out the signal from U23. Then the analog to digital converter (ADC) U24 converts this to digital format which is read serially by the meter microprocessor. DC Only The signal from buffer U54 is routed through U39 pins 14 and 15 for dc only mode. U29 and U31B form a five-pole low-pass filter with a cutoff frequency of 5 Hz. This removes all mains and higher frequencies. The resultant dc is then routed to the ADC. Resistance Measurement The current source used for resistance measurement is on the A1 Power PCA and is described above. U15 inverts the signal and U39 pins 14 and 15 and U39 pins 2 and 3 are toggled to rectify it. The signal at U46 pins 12 and 13 blanks both polarities for a period after the current is switched to eliminate inductive and capacitive effects. Relay Drivers U37, U36, U55, and U56 drive the relays on the A2 Meter PCA. The circuit is similar to the relay drivers section described in the A1 Power PCA section. Meter Power Supplies The meter is galvanically isolated from the earthed circuits. The power supplies are isolated by using isolated dc to dc converter modules. U48 is an isolated dc to dc converter modules that generates the +12 V isolated supply from the earthed +12 V supply for the relays. U51 is another dc to dc converter that outputs +5 V. U50 reregulates this down to +3.3 V for the meter microprocessor. U49 outputs ±12 V used by the amplifiers and analog switches on the meter input. U53 and U52 re-regulate these to ±5 V for the remainder of the amplifiers. Relay Disable The overvoltage signal from page 1 of the meter schematic, /FAULT_SENSE, sets the RS flip-flop composed of U47A and B. This signal causes the /RELAY_EN (not relay enable) signal at U19 pin 13 to go high, shutting off all relay drivers in the instrument. To clear this fault, the meter microprocessor sets pin U47 pin 2 low to clear the flip flop. U14 is a brown-out detector which will also set the flip-flop at power up and power down to prevent the relays from being in undefined states while the microprocessor is powering up and down. The /GFI_SENSE signal from the differential transformer on the power PCA is at mains frequency analog voltage. This is rectified and filtered by CR8 and C67. DAC U16 generates a digitally controlled voltage that is compared to the GFI signal at U17. When the voltage proportional to the GFI current exceeds the preset voltage, the output of U17 goes low setting the flip-flop, U47C and D, and, in turn, disabling the relays. Applied Parts The applied parts relay drivers, U32, U33, U34, and U35, operate as described previously. Each applied part post can be connected to several circuit points: Open, ECG Wave, Earth, +Meter, -Meter or 500 V. For the V1 post this is performed by relays K1, K2, K12, and K11. The other apples parts jacks operate similarly.

Meter Microprocessor U40 is the meter microprocessor. It is a single-chip controller with built-in Program memory (FLASH), RAM, serial peripheral interfaces, and timers. Calibration data and configuration data is stored in an external serial EEPROM (U44). The processor is clocked at 12 MHz by the crystal, Y2. The two microprocessors in the Analyzer communicate over a galvanically isolated serial port with U42 providing the isolation. The U/I processor is the master and can reset the meter microprocessor through U43. U41 is a brownout detector that resets the processor on power up and power down. The JTAG port (J21) is used for debugging and downloading firmware. User Interface Microprocessor U2 is the user interface microprocessor. It contains program memory (FLASH), RAM, timers, I/O ports, and communication ports. It is clocked at 12 MHz by the crystal, Y1. It runs off of the +3.3 V power supply and an internally generated +1.8 V supply. U1 is a serial FLASH memory for storing test data. U59 is an FRAM for temporary test data storage. Only entire test records are transferred to the FLASH memory. The warning LED DS1 is turned on by the U/I microprocessor to indicate when there are dangerous voltages or currents on any test jacks. The beeper, LS1, beeps as required. The internal temperature of the unit is monitored by RT1. At a preset temperature, the U/I microprocessor informs the meter microprocessor to shut down the relays and a message is placed on the display. The JTAG port (J2) is used for debugging and downloading code into FLASH memory. Keyboard and Display The keyboard and display are controlled by the U/I microprocessor. The Keyboard, S3 and S4, is arranged in rows and columns. It is read by consecutively setting each row line low and then reading the columns. The key pressed is at the intersection of the row and column. The display is controlled by the Display controller, U3, which is connected between the U/I microprocessor and the display at J1. Quad op-amp U6 generates the voltages needed to bias the LCD display. Switching voltage supply U5 generates the highest voltage in this string, and by varying this, the contrast is varied. This is varied by the CONTRAST signal at R22. The display can be shut off by the ENABLE_20 V signal which disconnects the +12 V supply from the +20 V supply. The display backlight can be turned on and off by Q3. USB Port U7 and U8 form the USB port. U8 provides galvanic isolation between the Analyzer and the communication port. U7 communicates with the U/I microprocessor in RS232 format. It converts incoming data from USB to RS232 and outgoing data from RS232 to USB format. U9 protects the port from ESD. The connector, U3, is a standard “type B” upstream pointing USB connector. The components on the USB side of the isolator, U8, are bus powered. U/I Power Supplies U11 is a switching regulator that generates the +3.3 V supply for the U/I microprocessor. U10 is a linear regulator that generates a 3.0 V supply for the display driver.

Analyzer Verification The following sections cover the setup and procedural steps for verifying the Analyzer is operating within the product specifications. Outlet Tension Tests To test the equipment outlet for proper tension: 1. Insert the tension tester into the hot (L1) pin of the Analyzer test receptacle. Set the tension tester to measure peak ounces. 2. Zero the tension tester indicators. 3. Slowly pull the tension tester out of the receptacle. 4. Read and record the reading on the tension tester. 5. Repeat steps 1 through 4 on the neutral and ground pins of the test receptacle. Setup Perform the following steps to prepare the Analyzer for performance verification. 1. Power on all test equipment and allow a 1-hour warm up time. 2. Power on the PC and log in.

3. Connect the PC USB cable to the Analyzer. 4. Power on the Analyzer with the programmable ac power supply. 5. Establish serial communication with the Analyzer (Applicable COM port using USBView, 115200 Baud, N,8,1 bits, HW Flow control) Under File→ Properties and the Settings tab, click the ASCII Setup button, and ensure “Send line ends with line feeds” and “Echo typed characters locally” are CHECKED. 6. If the Analyzer is a non-US unit, the firmware must be switched to indicate a US version. a. Send command: REMOTE=F2810

Note Many tests are preceded by the HIGH_RES-ON, and STD=XXX commands. These settings will not be “lost” when switching between tests, and are not required to be repeated if the Analyzer hasn’t been taken out of remote mode. They are intended to allow the procedure to be used in part or in whole for testing. Use them as needed throughout this procedure. When an MREAD is used to report a reading, the tenth reading is often specified. This is to allow settling time for the Analyzer. However, any reading after stabilization is sufficient. Verification Procedure The following steps make up the procedure for verifying the operation of the Analyzer and coincide with the verification datasheet found in Appendix A. A. Functional 1.

Remote Operations Introduction

Introduction The Analyzer is designed for remote operation by sending it commands through its computer port. Measurement data and command responses are returned through the computer port for computer or user analysis. This remote capability can be employed to automate the verification, calibration, and troubleshooting procedures described in this manual. Extensive automation can be realized by writing a computer program that sends commands to the Analyzer and evaluates the responses to generate a user report. Or, individual commands can be typed and responses read using a program such as Hyperterminal. The degree of automation is up to the users needs. This chapter describes how to connect and setup the Analyzer for remote operation. Also included is a complete list of valid commands, each with a functional description, proper command syntax, Analyzer response, associated command parameters, and examples. A set of diagnostic commands are also included to help isolate problems in some functions and circuits while troubleshooting the Analyzer.

Serial Communication Connections When unprogrammed devices are connected to a PC, they look different to Windows. Without intervention, Windows will enumerate each device separately. To force Windows to ignore the serial numbers of FT232R devices, add a registry setting. •

Edit the registry to add an entry at: "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\UsbFlags\".

•

Add a REG_BINARY entry "IgnoreHWSerNum04036001".

•

Set the binary value to "01".

•

Refer to FTDI Application Note AN232B-10 "Advanced Driver Options".

Note This only works if you add the registry entry before connecting any FTDI devices. You might have to uninstall FTDI device drivers with their "FTCLEAN" utility, then reload the drivers. You can force Windows (2000, XP, and above) to use the LocId of the USB port so all FTDI devices on a port are assigned to the same COM port number. Refer to FTDI Application Note AN232B-07 "Configuring FTDI's VCP Drivers to use Location IDs". Note If you properly set IgnoreHWSerNum04036001 as described above, you shouldn't have to use LocId.

Serial Communication These are common specifications for all serial ports: Baud rate: 115,200 baud Format: 8 data bits, no parity, 1 stop bit

Modes The following is a list of Analyzer modes with a brief description of each: 1. Power Up •

start-up mode. •

The display shows a “splash” screen during this period.

2. Local •

This is the default mode entered after power-up.

•

The user controls the Analyzer by pressing buttons and viewing the display.

•

The computer interface is active at any of the user menus, but the UI can only execute a few commands: those that put the Analyzer into remote mode or request instrument status. All other commands are illegal.

3. Remote •

The display indicates that the Analyzer is under remote control.

•

The UI receives commands from the USB interface to control the Analyzer.

The Analyzer can be put back to local mode by a command or by pressing a key.

•

The UI will directly execute some commands that it can without contacting the Meter.

•

Other commands not executable by the UI will be forwarded to the Meter exactly as received. Then, the UI will get the response from the Meter and pass it back to the computer as received.

4. Cremote •

Same as Remote Mode, except that responses from the Analyzer are enclosed in ‘packets.’ Commands from the PC to the Analyzer must also follow this format.

•

This protocol also applies to sub-modes within remote control.

•

When returning to Local Mode, the communication protocol is restored to normal operation.

•

The packet format is defined below: STX

Maintenance Introduction

5

Introduction This chapter covers the general maintenance as well as troubleshooting information for isolating failed Analyzer components. The Analyzer needs little maintenance or special care. However, treat it as a calibrated measuring instrument. Avoid dropping or other mechanical abuse that could cause a shift in the calibrated settings.

Testing and Replacing the Fuses XW Warning To prevent electric shock, remove all power cords and test leads from the Analyzer before opening the fuse door. For electrical protection of the equipment outlet, the Analyzer uses two fuses, one in the live (L1) line and one in the neutral (L2) line. To test the fuses, do the following while referring to Figure 5-1: 1. Turn the Analyzer so the case bottom is facing up. 2. Flip up the tilt stand. 3. Remove the fuse door from the Analyzer by removing the screw holding the fuse door with a #2 Phillips head screwdriver and lifting the fuse door from the Analyzer. 4. Remove the fuses from the Analyzer.

F1 - F2

Figure 5-1. Fuse Access

fis111.eps

5. Using a multimeter, measure the continuity of each fuse. If one or both fuses do not show continuity, replace the fuse(s) with fuses that have the same current and voltage rating. Appropriate fuse ratings are posted on the case bottom label of the Analyzer. The final assembly table in the Replaceable Parts chapter lists available fuses with Fluke Biomedical part numbers. 6. Reinstall the fuse door and secure it with the screw.

Cleaning the Analyzer XW Warning To avoid electric shock, do not clean the Analyzer plugged into mains or attached to a DUT. W Caution Do not pour fluid onto the Analyzer surface; fluid seepage into the electrical circuitry may cause the Analyzer to fail. 5-3

ESA612 Service Manual

W Caution Do not use spray cleaners on the Analyzer; such action may force cleaning fluid into the Analyzer and damage electronic components. Clean the Analyzer occasionally utilizing a damp cloth and mild detergent. Take care to prevent the entrance of liquids. Wipe down the adapter cables with the same care. Inspect them for damage to and deterioration of the insulation. Check the connections for integrity before each use.

Disassembly/Assembly To disassemble the Analyzer, do the following: 1. Turn the Analyzer so the case bottom is facing up. 2. Remove the six screws in the case bottom with a Philips screwdriver 3. Lift the case bottom off of the case top and disconnect the cables that connect the two circuit boards together. The A1 Power PCA will remain attached to the case bottom and the A2 Meter PCA will remain with the case top. To reassemble the Analyzer, follow the disassembly steps in reverse order.

Troubleshooting The verification procedure contained in this manual is an effective troubleshooting tool; based upon the section of the test that has failed, or on the failure mode, the component that has caused the malfunction can be isolated. Power on Failure If the Analyzer fails to power up, verify fuses F1 and F2 inside the rear fuse-panel door have not blown. If they have not blown, verify power is applied to the power inlet assembly and that the wiring on the power switch internal to the device is correct. Failures during power up are usually related to mismatched firmware or to power supply problems. To verify firmware, if the device will power up and gives an “Initialization Error,” it may be possible to reach the remote mode through the USB port. Establish hyperterminal communication with the device and send the following command: REMOTE=F2810

If the device displays “Remote Mode” on the front panel and responds with a “*,” determine the firmware status. CAL=F2810 Receive * IDENT

Receive the meter and UI firmware builds. Verify that the two are matched; if they are not, upload the latest firmware to the device and try again. If the firmware matches and is up to date, verify the power and data cables connecting the A1 Power PCA and A2 Meter PCA are connected at J4 and J7 on the power board and at J4 and J20, respectively, on the meter board; also inspect the soldering of the connectors to the pcas. If these connections are not at fault, verify the power supplies for the processors and for the device as a whole are functional. First verify U9, the power supply module at the bottom of the power board, is functional and that CR4, the red LED, is on. Then verify the outputs of U12 and U28 are correct. On the meter board, check that Q9 and U48 – U53 are all operating correctly. Finally, check the power inputs and resets to the microprocessors.

Maintenance Troubleshooting

Output Failures If sourcing a current or voltage through the electrical outlet, such as during an Earth Resistance, or powering a device with normal or reversed polarity, such as during a leakage test, and no signal is applied to the electrical outlet, failures could reside in the physical construction of the electrical outlet, in the reversing relays, or in the signal generation circuit. Verify the electrical outlet wiring is in accordance with the J1 annotation on the pca. Also, if troubleshooting an Australian Analyzer, measure the impedance of the ground connector of the electrical outlet; some outlets have been found to have more than 0.5 Ω. These should be replaced. For US electrical outlets, ensure the backing plate is fully installed; this forces the insulation displacement crimp connection to engage. If this backing plate has been separated, replace the entire electrical outlet. If sourcing a mains power source through the electrical outlet, measure the voltage at the electrical outlet in normal and reversed polarity. If the power configuration is incorrect, inspect the reversing relays on the power PCB: K1-K2, K4-K7. If GFCI trips are also a symptom, verify proper operation of the solid-state relay. K9 and K10 deliver the insulation resistance and MAP signals to the equipment outlet, respectively, and are a good place to half-split the source circuit. The protective earth resistance signal is selected via K12. For leakage measurements, the return path from the electrical outlet is selected by K14. The MAP signal is generated by transformer T1 and regulated by Q1, Q2, and the supporting resistors and is routed through K16 and K17. The insulation resistance voltage is created by transformer T2 and rectified by the nearby circuitry, including Q7; the resultant signal is sensed by U24. Meter Failures While most measurements made by the Analyzer are made by the A2 Meter PCA directly, several are detected or analyzed directly on the A1 Power PCA. MAINS Power Most Mains voltage measurements that are erroneous are the result of power supply failures in U9, isolated supply U18, or in calibration failures. If a calibration error is suspected, calibrate the Mains voltage to determine if this can correct the problem. Otherwise, evaluate F3, the resistor network R2 through R7, U3, and U4 for failures. Differential Current and Equipment Current Both differential and equipment currents are measured at the outlet of the reversing relays, just prior to the Equipment Outlet using L1 and L3, respectively, installed on the backside of the A1 Power PCA beneath the SSR. If all the solder connections on the inductors are good, verify U1, U8, and the supporting circuitry. Meter Troubleshooting If the source signal is functional for a particular measurement, but no measurement is read by the Analyzer, then the meter inputs are suspect. K13 and K15-K18 connect the meter jacks, Red, Black, and Null, to the positive and negative sides of the meter for measurement or resistance nulling. The patient load is the circuit by which a human body is simulated for patient leakage measurements, and is comprised of R78 and R79 (800 and 200 Ω, respectively). For greater leakage currents of 2 mA or more, the meter input is shifted from R78 to R79. To troubleshoot leakage measurements, for ac measurements, half split the circuit at the output of the rms converter, U23 pin 5 or the input of the low pass filter, U31 pin 3. The input to the analog-to-digital converter for ac measurements is at TP95. For dc measurements, use the output of the low pass filter, TP 91. 5-5

ESA612 Service Manual

Resistance measurements are driven by the power supplies on the A1 Power PCA, but is inverted by U15. Applied parts problems should be troubleshot separately than leakage measurements, if possible. First, determine if a single ECG post is affected, or the entire bank. If a single ECG has a failure, inspect the diodes CR24, 29, and 46, L9, or relays K9, K10, and K22 (or respective components with other ECG posts). If all applied parts are affected equally, verify K11 or inspect the signal source (MAP, 500 V dc, etc). For ECG waveform problems, the buffer U13 or resistor network of R5361 drive the entire circuit; the waveform itself is generated by the meter microprocessor. U/I and meter microprocessor failures will normally result in complete nonfunctionality of the Analyzer. Calibration data table and configuration information failures indicate a problem in U44; a loss or corruption of stored test data indicates a failure in U1 or U59. Display board failures are investigated through the driver, which consists of U3 and the power supply of U5, U6, R22 and Q3. Otherwise, the display is replaced as a unit.
