No.: 9.9 Supersedes: Superseded by: rief description The Comet exposure interface (IF Comet for short) is available as an option for the Stadler X ray generators. metering chambers of manufacturer "Comet" can be connected to the IF Comet. Identically designed metering chambers of other manufacturers may also be used. The metering chamber generates a current proportional to the dose. The IF first converts this current to a voltage and then converts it to a frequency. In addition, the "IF Comet x Power Infeed" board must be connected for the IF Comet. \\Dc\dfs\Corpdata\Produktion und Logistik\Produkte\ geprüft und freigegeben\se 0X0\Dokumentation\990 Übersicht IF Comet SE0X0 EN.doc /

2 Overview IF Comet SE0X0 This document and the information contained herein are the property of Stadler Elektronik G ahnhofstr., 0 Littau, Doc. No.: 9.9 Mode of operation The IF Comet consists of identically designed channels (one channel per metering field and this, in turn, for both metering chambers means channels). The descriptions below consequently apply to each of the channels. Mode of operation of the IF Comet in brief: The metering chamber creates a current proportional to the dose. The IF first converts this current to a voltage using a currenttovoltage converter. In turn, this voltage is converted by a voltagetofrequency converter to a proportional frequency. Finally, this frequency is evaluated by the generator CPU. The IF Comet x Series is set with potentiometers. n incorrect basic setting of the potentiometers may, under certain circumstances, lead to distortion or limitation of the metering chamber signal which, in turn, results in a malfunction of the IF in the critical range. For this reason, all potentiometers must be set as specified in the. of the offset potentiometer: The offset potentiometer compensates for the closedcircuit current of the metering chamber (the offset voltage). of the trimmer potentiometers: The trimmer potentiometers are used to intermatch the metering fields so that all metering fields switch off at the same dose. The trimmer potentiometers must be set to the basic setting beforehand. This procedure is referred to as "pulse count calibration". /

No.: 9.9 Supersedes: Superseded by: Safety information Caution: Hazardous voltages The IF Comet power infeed board uses 0 V mains voltage! rief description Unlike the IF 9 (familiar from the SE000, SE000 and SEX00 Xray generators), the IF Comet x Series requires a separate V/ V power infeed. The reason for this modification is that this separate power infeed introduces less interference with, consequently, less negative impact on the measuring signal. Mode of operation The IF Comet power infeed generates a V power infeed and a V power infeed from 0 V C. The 0 V power infeed is fused with a 0 m slowblow fuse. \\Dc\dfs\Corpdata\Produktion und Logistik\Produkte\ geprüft und freigegeben\se 0X0\Dokumentation\990 Übersicht Speisung IF Comet SE0X0 EN.doc /
