STANDARD CONTROL UNIT PORTABLE X-RAY GENERATOR Increase the reliability of on-site X-ray techniques while decreasing their costs GENERAL FEATURES PERFORMANCE Being designed on the basis of industrial PC boards (tropicalised SMD technology) equipped with the 80286 INTEL processor, the SITE-X standard control unit offers a degree of reliability rarely attained with industrial equipment manufactured in small batches. Its transistor power circuit enables the operator to have virtually no knowledge of the characteristics of the network or the generating set to which it is connected. Like all the generators in the range, the SCU286 is guaranteed IP65 weatherproof. It achieves all its nominal performances between -25° and +55°C ambient temperature. Its weight is 14 kg and its ergonomics and robustness are exemplary. MAINTENANCE A very efficient resident maintenance software determines the origin of any failure within a few seconds with a degree of uncertainty of less than 5%. Most of the problems can now be resolved on site by replacement of the board or component indicated by the program. To guarantee the accuracy of the radiological parameters the SCU286 has a system for direct measurement of the high voltage delivered by the X-ray generator. Based on this data the control system maintains the stability of milliamperes and kilovolts to within ± 0.5% in any selection range. Because they are virtually exempt from fluctuations in the power supply, SITE-X units offer a totally constant quality of exposures. OPERATOR INTERFACE The front panel is made of high-strength polyester film which incorporates a sensory-type 16-key keypad. Pilot lights, powering-on, interlock switching, “START” and “STOP” functions are provided by broad and robust indicators, switches and push buttons. A high brightness display, protected by an antireflection screen, gives all the useful information in the language of your choice. RMS and peak voltages, frequency of the power supply, date and time, internal temperature, choice of language or the time zone can be called up or updated from the keypad. A freely programmable system of access codes at three levels (supervisor, operator and service engineer) limits the access to certain functions. Disconnectable if necessary, this security system is nonactive by default (except for the servicing functions). DATABASE The SCU286 control unit is intended above all to be user-friendly. In order to reduce the number of test shots to a minimum, the operator can, if he so wishes, utilise a virtually unlimited source of standard exposures which he himself will have made during the preceeding campaigns. All the radiological parameters of exposure are memorised by operation of a single key : kilovolts, milliamperes, exposure time, film type, focus-film distance, type of materials, controlled thickness and density of the film. Future search for the optimum exposures will be based on a specific test case and will no longer necessarily be determined by the recall of an abstract serial number which moreover is impossible to memorise. The contents of the database can readily be printed or transferred from one control unit to another through RS232 serial link.
