INTERLOCK/STATOR
OVERVIEW
This section describes the operation of the following circuits:
• Generator Interlock
• Pre-charge
• Stator
These circuits are initialized and checked by the Technique Processor during the boot
sequence. If a failure is detected during boot-up, the system will hang, not completing the
boot sequence. An error message may be displayed on the Control Panel Display.
After system boot, the Technique Processor continues to monitor these circuits. An error
message is displayed on the Control Panel Display and X-rays are prohibited, if a failure
is detected.
