2- THEORY of OPERATION2.1 Overview

The Vectra series electrotherapy products are comprised of several PC board assemblies housed within a common enclosure. These assemblies each support a distinct function in the product. The basic elements are User Interface, Control Board, Stim Generation Board, Ultrasound Board, Ultrasound Applicator, and Power Supply Circuits.See Figure 2.1 below.

FIGURE 2.12.2 Power Supply Circuits

A universal input power supply provides all parts of the system with 12 volts DC. The supply is connected to the mains at all times when the cord is attached. The power switches on the top of the unit, switch the 12V output of the power supply to the different components in the system by way of the Power Distribution Board. The 12V supply is regulated locally at each PC board as required.

2.3 Control BoardThe Control Board serves just as its name implies. It controls the operation of the stim boards, ultrasound boards, user interface, and accessories. The control board communicates to the stim boards and ultrasound board through a proprietary 8-bit parallel bus. The control board drives the display. The control board reads the touch screen or menu buttons. The control board also reads the amplitude and contrast controls. The control board manages the ZIP drive andinfrared printer port. The control board through the power supply distribution board operates the gel warmer. Sound output is generated by the control board and routed to an internal speaker or alternately to external speakers. The control board reads the patient switch or manual stim switch.

Vectra™ Pro

2- THEORY of OPERATION2.4 Stim Generation Board

The stim board creates all muscle stimulation output. Communications to the stim board is via an 8-bit data bus and a dual-port RAM. A processor on the stim board acts on messages passed to it by the control board to set upwaveforms and adjust output amplitude. Information can likewise be passed from the stim board back to the controlboard for monitoring current, GSR mode levels, etc. If the stim board does not respond as expected to a commandfrom the control board, output is stopped and an error message is generated.

2.5 Ultrasound Board and ApplicatorThe ultrasound board generates the 1 or 3.3 MHz output to drive the ultrasound applicator. The ultrasound board is accessed much like an I/O port by the control board. It can provide current and voltage information about the ultrasound output of the board. The calibration data for the applicator is passed through the ultrasound board fromthe applicator up to the control board. By storing the calibration data in the applicator there is no calibration necessary for the ultrasound board and any calibrated Chattanooga Group, Inc. compatible applicator can be attached and operated to provide accurate output.

2.6 User Interface and AccessoriesThe LCD or EL display panel provides the operator visible feedback in the way of menu choices. Pressing the touchscreen or menu buttons makes selections from the menus. The control board interprets these user inputs andresponds accordingly. Audible feedback is given as well for events such as keypresses and end of treatment. The control board accesses the ZIP drive via an IDE interface. Treatment presets can be exported and imported using the disks, as well as giving patients pre-treatment information or the user in-service instruction. The 5 voltsnecessary to operate the drive is generated on the power supply distribution board.The infrared printer port works exclusively with the Jeteye infrared to printer interface unit. This allows printing treatment information to any type of printer the user might have. Due to the large number of printers available, direct printing to infrared-capable printers is not supported.

2. Check pins 5 and 7 of U15 (see “A” on schematic) for presence of square wave. See Figure 5.41.

NOTE:Perform step 2 at 1MHz and 3.3MHz settings @ 100% DutyCycle.

3. Absence of square wave at any or all of the check points in step 2 indicate bad Ultrasound Board. Replace with Part Number 79291D.

B. Head Detect Voltage TestPerform this test with all available Ultrasound Applicatorsavailable for the unit being tested (2cm2, 5cm2, 10cm2). This willaid in isolating bad board or bad Ultrasound Applicator.

1. Plug in the Ultrasound Applicator.2. Using a Digital Multimeter, check the voltage at #1 and

#2 of L13. See “B” on schematic. See Figure 5.42 for voltage specifications.

3. Repeat steps 1 and 2 with all other available Ultrasound Applicators for unit being tested.

4. If multimeter reads 5VDC, plug in a known good Ultrasound Applicator and re-test. If voltage is in spec per Figure 5.42, then Applicator is bad. If voltage reads5VDC with known good Applicator, then Ultrasound Board is bad. Replace board with Part Number 79291D.
