X-Ray safety circuit #1
Safety Circuit #1 consists of:
contactor K52 (activation of high voltage generation);
relay K6 (auxiliary function);
relays K8 through K11 (monitoring the sample seal position switches S659 through S662);
safety switches S651, S653, S655, S657 (monitoring the side panels);
tripline (monitoring the X-ray source, the high-voltage cable, and the cover of the sample entry
position); and
safety relays K1 and K2 (controlled by the safety microcontroller).
If all of these switching contacts are closed, the "heating voltage" (see signal "Heating Voltage
+24VDC") will be transferred via a fuse to the X-ray generator. This voltage will activate contactor K52
inside the X-ray generator and enable the generation of high voltage.
X-Ray safety circuit #2
Safety Circuit #2 consists of:
contactor K53 (activation of high voltage generation);
relay K7 (auxiliary function);
relays K8 through K11 (monitoring the sample seal position switches S659 through S662);
safety switches S652, S654, S656, S658 (monitoring the side panels);
tripline (monitoring the X-ray source, the high voltage cable, and the cover of the sample entry
position); and
safety relays K1 and K2 (controlled by the safety microcontroller).
If all of these switching contacts are closed, the "heating voltage" (see signal "Heating Voltage
+24VDC") will be transferred via a fuse to the X-ray generator. This voltage will activate contactor K53
inside the X-ray generator and enable the generation of high voltage.
