  • Page 16: Section 3 : Description For Functions

    SECTION 3 : DESCRIPTION FOR FUNCTIONS   [1] GENERAL The Belmont Belray II model 097 is advanced 70 kVp intra-oral x-ray machine consisting of four major components: tube head, balance arm, main controller and sub controller. Because of its modular design, sub controller can be readily remotely located to accommodate room design and radiation control requirements.

  • Page 17: Automatic Voltage Regulator

    [2] AUTOMATIC VOLTAGE REGULATOR 1. Model 097 is equipped with the automatic voltage regulator (AVR) in the control box. Purpose for this function is as follows. a. As the line voltage fluctuation (including voltage drop during exposure) is absorbed, stabilized voltage is supplied to the high voltage transformer and filament transformer.

  • Page 18: Overcurrent Protection

    [4] PRIMARY CIRCUIT OF FILAMENT TRANSFORMER   (1) CIRCUIT AND OPERATIONAL TIMING 1. Parallel circuit of resistor and transistor is added in series to the AVR circuit and applied to the primary circuit of filament transformer. 2. As Triac is not inserted in this circuit, voltage is applied to the filament transformer if the relay mentioned above turns on.

  • Page 19: Section 4 : Adjustment

    SECTION 4 : ADJUSTMENT [1] AVR VOLTAGE Output voltage of Automatic Voltage Regulator circuit can be measured and adjusted as follows. If AVR voltage has been adjusted, tube current must be adjusted after that. 1. Prepare a digital multimeter capable to measure 100 Vac with 1 % or more accuracy. 2.
  • Page 20 Alternative method to adjust AVR voltage Adjusting method of AVR voltage on page 18 requires the tube head to be connected. If by any reason AVR voltage should be adjusted without head, following method can be used. In this method the reference voltage for AVR circuit is adjusted. 1.
  • Page 21 [2] INSPECTION OF TUBE CURRENT Model 097 has two types of self measuring function for tube current, i.e., auto mode manual mode. Tube current can also be measured directly by multimeter. In auto mode, both tube current at the beginning and stabilized period of exposure are checked and adjusted automatically, although the values of tube current are not displayed.
  • Page 22 c. Direct measurement 1. Prepare a multimeter capable to measure 5 Vdc with 1% accuracy within 1 second. 2. Turn off the main switch. 3. Open the front panel of main controller. 4. Set to the suitable range of multimeter to measure 5Vdc. 5.
  • Page 23 3. Keep depressing P (patient), C (cone), F (film) button until "e.XX" is displayed on the exposure time window. 4. Select the tube current that should be adjusted. 5. Press T2 switch then display changes to "e.XX". XX is the value presently memorized. 6.

  • Page 24: Section 5 : Periodic Inspection And Adjustment

    SECTION 5 : PERIODIC INSPECTION AND ADJUSTMENT Following inspections and adjustments should be performed after installation, when parts are changed, and once a year by a trained service technician to ensure that the x-ray unit is functioning with the manufacturer's specifications and remains in compliance with the standard. [1] ELECTRICAL INSPECTION AND ADJUSTMENT (1) POWER SUPPLY VOLTAGE Power supply voltage must be within the operable range...

    SECTION 7 : TROUBLE SHOOTING Error code is displayed in the exposure time display window for most troubles in daily usage. So the error code table in section 6 can be used as trouble shooting chart in most case. Some troubles that don't make error code displayed are listed in the following table with their possible causes, check points and solutions.

    SECTION 8 : REPLACEMENT OF COMPONENT [1] CONTROL BOX (1) POWER GENERATING PCB 1. If one or more results of verification checks are out of specification or trouble shooting chart indicates, power generating PCB should be replaced. 2. Since power MOS FETs and C-MOS micro computer chips are used, great care should be paid against electrostatic discharge (ESD).
