X-Ray On, X-Ray Disable
The Generator does not receive drive signals unless both X-ray Enable and X-ray ON are asserted. X-Ray Enable is generated
by a hardware switch closure (top button, hand or footswitch), whereas X-Ray ON is generated by software. Both must be active
to allow X-Ray generation, which prevents a single fault condition from allowing uncommanded X-rays.
Status of these lines is displayed at LED DS2 on the HV Supply Regulator PCB. LED XRE shows a hardware switch closure
when lit and LED XRO shows when illuminated that software signal X-Ray ON is active.
