Page 203 CPI Canada Inc. Troubleshooting The generator purges the existing X-ray tube auto calibration data before starting the auto calibration routine and saving new calibration data. Therefore, auto calibration should be a last resort during general troubleshooting, and should only be done to recalibrate the tube. For example, if a low mA fault is presented, you should ensure that the generator is fully functional, and actually needs recalibration.

CPI Canada Inc. Regular Maintenance 6.9.0 TUBE CONDITIONING / SEASONING Tube conditioning or “seasoning” is particularly important for new tubes or tubes that have not been used for several days. This should be performed on each X-ray tube before attempting auto calibration, as an unseasoned tube may not operate properly at higher kV values without arcing.

Regular Maintenance CPI Canada Inc. 6.10.0 END OF PRODUCT LIFE The generator’s useful life has been estimated at 10 years from point of sale. This will vary depending on use and environmental conditions. If the generator has completed its useful service life, local environmental regulations must be complied with in regard to disposal of possible hazardous materials used in the construction of the generator.

Page 218 Theory of Operation CPI Canada Inc. 7.1.0 INTRODUCTION This chapter contains the theory of operation for the CMP 200 X-ray generator. The theory of operation is organized by functional blocks as depicted in the functional drawings in chapter 9. 7.2.0 FUNCTIONAL THEORY OF OPERATION Refer to the appropriate functional block diagram in chapter 9 in conjunction with the theory of operation in this chapter.
Page 219 CPI Canada Inc. Theory of Operation 7.2.2 DC bus & power distribution (MD-0831) Sheet 1 applies to single-phase generators. Assuming that the AC mains is connected and switched on, line voltage is applied to the primary of the auxiliary transformer via F8 and F9. This will establish the +/-35 V supplies via F1 and D1, and the +24 V supply via F2 and F3, and D3 / D4.
Page 220 Theory of Operation CPI Canada Inc. 7.2.2 DC bus & power distribution (Cont) LED DS1 on the H.V. auxiliary board confirms the presence of the +24 VDC supply, and an LED (DS1) located on the EMC capacitor board indicates that the DC bus is charged. The console board contains a 300 VAC (approximately) power supply that drives the cold-cathode fluorescent lamp in the LCD display assembly.
Page 221 CPI Canada Inc. Theory of Operation 7.2.3 Room interface (MD-0833) +24 VDC, 120 VAC, or 240 VAC for the BUCKY DRIVE is available when K6 on the H.V. auxiliary board is energized as described in 7.2.2. The 24 VAC and 24 VDC supplies are present at all times that the AC mains is energized.
Page 222 Theory of Operation CPI Canada Inc. 7.2.5 kV control and feedback (MD-0835) Refer to MD-0835, sheet 1: Prior to the X-ray request being received, the CPU supplies base current to Q17 on the generator control board, turning Q17 on. Q17 then supplies base current to Q16, turning Q16 on, thus holding the junction of R178 / R179 high (+12 V).
Page 223 CPI Canada Inc. Theory of Operation 7.2.5 kV control and feedback (Cont) Refer to MD-0835, sheet 2 and 3: The inverter board(s) produce the high power drive for the HT transformers (30, 32, and 40 kW generators use one inverter board, 50 kW units use two inverter boards). The output of the inverter board(s) drive the primaries of the HT transformers via the resonant capacitor and the resonant / EMC / sharing inductors.
Page 224 Theory of Operation CPI Canada Inc. 7.2.6 Filament drive and mA control (Cont) Refer to MD-0836, sheet 2: When an exposure is being made, 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 of the generator control board.
Page 225 CPI Canada Inc. Theory of Operation 7.2.8 DAP (MD-0840) The DAP circuits consist of micro-controller U11, RS-232 driver U13, and associated components on the generator control board. Micro-controller U11 operates under control of the CPU on the generator control board, and controls all DAP functions (switches the +15 V supply via Q4, Q6, and Q8 as required to control and test the DAP device, and counts the DAP pulses via U13).
Page 226 Theory of Operation CPI Canada Inc. 7.2.10 AEC (MD-0838) Refer to MD-0838, sheet 1: This shows the circuits on the generator control board that provide interfacing between the generator CPU and the AEC board. Eight lines supply the AEC chamber select signals, the start signal, and the field select signals to the AEC board via U2 and driver U26.
Page 227 CPI Canada Inc. Theory of Operation 7.2.10 AEC (Cont) The start signal also originates on the generator control board. This signal, when active, will cause DS5 on the AEC board to light. The start signal is buffered and inverted by U2F and U2E, and will be logic low at the output of U2E when the start signal is active.
Page 228 Theory of Operation CPI Canada Inc. 7.2.10 AEC (Cont) The output of U2B will be a positive going ramp regardless of the AEC chamber type in use. This ramp voltage is processed by U4A and U4B, and also fed to the short AEC exposure time compensation circuit consisting of R11 to R14, S3A to S3D, R53 and C11.
Page 229 CPI Canada Inc. Theory of Operation 7.2.10 AEC (Cont) Refer to MD-0838, sheet 5: This shows the signal processing circuits for AEC board assembly 737992. The AEC channel 1 to channel 4 outputs are connected to the inverting input on U11B, and a sample and hold circuit is connected to the non-inverting input on U11B.
Page 230 Theory of Operation CPI Canada Inc. 7.2.10 AEC (Cont) The start signal also exits from the generator control board. This is inverted by U6, and then inverted again by Q4 and Q5. The output of Q5, when active, opens the analog switch that is part of the sample and hold circuit at the input of U8A during an AEC exposure.
