For the membrane console, the +24 V supply is regulated to +5 V, +3.3 V, +1.2 V, and -20 V via F1 on the console board. The console board contains a 300 VAC (approximately) power supply that drives the cold-cathode fluorescent lamp in the LCD display assembly.
  • Page 247 Theory of Operation 7.2.4 X-ray exposure (Cont) Pressing X-RAY on the membrane console will energize U17 on the console board. If U17 is energized, or one of the X-RAY switches on the touchscreen console, X-ray mini-console, or on the associated hand switches is pressed, U9 and U7 on the generator control board will be energized.

  • Page 248: Kv Control And Feedback (Md-0932)

    Theory of Operation 7.2.5 kV control and feedback (MD-0932) Refer to MD-0932, sheet 1: When there is no X-ray request by the CPU, the RAD INHIBIT line from MD-0931 will be pulled high. This circuit is described in 7.2.4. When the RAD INHIBIT line is high, the junction of R131 / R123 on the generator control board will be held high (+12 V).

  • Page 249: Filament Drive And Ma Control (Md-0934)

    Theory of Operation 7.2.5 kV control and feedback (Cont) Refer to MD-0932, sheet 2 and 3: The inverter board(s) produce the high power drive for the HT transformers (32 and 40 kW generators use one inverter board, 50 kW and 65 kW units use two inverter boards). The output of the inverter board(s) drive the primaries of the HT transformers via the resonant / sharing inductors and the resonant capacitor and a current transformer that samples the HT primary current.

  • Page 250: Dual-Speed Starter (Md-0924)

    Theory of Operation 7.2.6 Filament drive and mA control (Cont) Refer to MD-0934, sheet 2: When an exposure is in process, X-ray tube current flows through series resistors on the HV anode and cathode boards. The voltage developed across these resistors, which is proportional to the X-ray tube current, is taken to J9 on the generator control board.

  • Page 251: Low-Speed Starter (Md-0935)

    Theory of Operation 7.2.7 Dual-speed starter (Cont) The modulated output from the inverter is fed to the common stator terminal via one leg of the inverter and via K4. The shift and main currents are taken from the other leg of the inverter via K5 and K6. K1-A switches the main current, and K1-B switches the shift current.

  • Page 252: Dap (Md-0938)

    Theory of Operation 7.2.9 DAP (MD-0938) The DAP circuits consist of switching circuits to control the outputs at J4, and circuits to feed the DAP pulses back to the CPU. Data latch U19 and driver U20 switch the +5 V and +15 V supplies via Q2, Q3, and Q1 as required to control and test the DAP chamber.

  • Page 253: Aec (Md-0936)

    Theory of Operation The generator control board includes two serial communications ports. These include J21, which is an RS-232 communications port, and J22, which is used for optional features. DS1 on the console board (membrane consoles) and on the generator control board will flash at a consistent 1 Hz rate if the related CPU is operational.
  • Page 254 Theory of Operation 7.2.12 AEC (Cont) The output of U2A connects to the common inputs of analog switches S2A to S2D. These analog switches are controlled by the chamber-select signal, and the switch corresponding to the active channel will be closed. This connects the output of U2A to the AEC gain adjustment potentiometer R1 to R4 corresponding to the active channel.
  • Page 255 Theory of Operation 7.2.12 AEC (Cont) The output of each preamplifier is connected to an analog switch used for field selection. Selecting the desired field closes the corresponding analog switch, connecting the output of that preamplifier to the summing node at the junction of R69, R9, R22 for channel 1, R40, R47, R55 for channel 2, R70, R11, R23 for channel 3, and R41, R49, R56 for channel 4.
  • Page 256 Theory of Operation 7.2.12 AEC (Cont) Refer to MD-0936, sheet 5: This is the functional schematic of AEC assembly 737998, used with ionization AEC chambers. The AEC chambers are connected to J1 to J4. The AEC signal from the AEC chamber(s) is routed to the input of analog switches U1A to U1D on the AEC board.

  • Page 257: Digital Interface (Md-0926)

    Theory of Operation 7.2.12 AEC (Cont) The channel 3 and channel 4 select lines from U6 are inverted by Q6 and Q7. The outputs of Q6 and Q7 are redesignated as the PORTRAIT and INVERTED signals, respectively. These signals select four different combinations of the L-M-R fields from the five available fields on the AEC chamber.

  • Page 258: Interconnect Diagram (Md-0939)

    Theory of Operation 7.2.13 Digital interface (MD-0926) (Cont) Refer to MD-0926, sheet 2: Sheet 2 shows the digital inputs from the digital imaging system. One input is a differential input that is fed to the data bus via U46 and U18, and six inputs are opto-coupled via U12, U16, U17, U22, U23, and U36.
