1. Equipment overview The XRC X-ray system has been designed to integrate seamlessly into the modern calibration facility. The compact design of the controller and the electronics cabinet, minimise the space required for the system. The XRC controller (HR or STD) can be supplied with the system, details on the different controller options can be found in section 3. The system can be supplied with a variety of X-ray tubes, generators, tube supports and accessories, allowing the customer to select the exact combination of equipment required for their research or calibration needs. The system can be Ethernet enabled (XRC HR and XRC STD controllers only), giving easy access to professional diagnostic and programming assistance. XRC System - Page 4 of 14

Touch screen technology structured on Siemens HMI multifunctional platform products provides world renowned design and reliability combined with simple to use processes are available for XRC HR and XRC STD controllers. Beam Start up Characteristics Each controller deals with all the routine elements of beam start up and beam warm up requirements. These characteristics are pre-programmed by Xstrahl Engineers to provide ease of use solutions for non technical operators, whilst maintaining secure and safe integrity over the operation of the x-ray dynamics of the equipment allowing reliable operation of the system Automatic Run up procedure In order to maximise the X-ray tube life two run up procedures are programmed within the control system. The controller automatically displays the required run up procedure when the system is powered on. Short (Daily) run-up 150kV to 315kV in 20minutes, with max kv running for 3 minutes Long (Monthly) run-up 150kV to 315kV in 70 minutes, with max kv running for 3 minutes If required, the daily run up procedure can be bypassed. The bypass mode is protected to avoid frequently switch off of the warm up procedure. It is not recommended to switch off the warm up procedure.
