14-3-6 X-ray Interlock Systems
“Deadman’s Switch” X-ray Control Safety System
X-ray emission is terminated instantly when you release the x-ray control
radiography pushbutton.
A special safety circuit uses a signal from second trigger (radiographic
exposure ) controls transmitted directly via relay contacts to the control circuit of
the power inverter. If the microprocessor does not stop x-ray emission after a
delay of several milliseconds, inverter operation is inhibited. In this case, a fault
signal is sent to the control circuits of the generator.
X-ray Tube Housing Overheat Interlock
If the factory-adjusted temperature of the tube housing goes higher than the
permissible level, x-ray emission is terminated.
If it occurs, ask the service Refer to troubleshooting chart.
