8 C-Arm Control
X-RAY SWITCH
The signals X-RAY_SWITCH and SECURITY connect at P5 on the Control
Panel Processor PCB and are sent to the Analog Interface PCB via the
Power/Signal Interface PCB and Mainframe Motherboard. See the X-ray
On/Disable section in this manual for details of these signals.
X-RAY_LAMP also connects at P5 and is sourced from the Power Motor Relay
PCB. This signal provides the return path for the lamp in the X-ray switch and is
derived through U1 from the signal X-RAY_ON which is the enabling signal for
X-ray production. X-RAY_LAMP also goes to the Workstation to drive the LED
array above the monitors.
On systems with serial number 69-2001 and higher, X-RAY_SWITCH,
SECURITY, and X-RAY_LAMP pass from the X-ray switch, through the new
Column I/O PCB directly to the Power/Signal Interface PCB. See the X-ray
On/Disable section for details of these signals.
