GE HEALTHCARE DIRECTION FC091194, REVISION 11 VIVID 7 SERVICE MANUAL Chapter 5 - Components and Functions (Theory) 5 - 37 5-3-16 Front-End Contro ller Board, FEC NOTE: The Front-End Controller Board is only used in Front-End Rack version 1. In units with Front-End Rack vers ion 2, the RFI board replaces the functionality of this board, see: 5-3-21 Radio Frequency Interface Board, RFI on page 5-61 . 5-3-16-1 General Description The Front-End Controller Board controls the transmitter and receiver boards. Most of the control is done through the Frond End Bus. Main tasks done by the FEC board: • System Master Clock generator • Transmitter Control • ATGC Control • Receive Focusing Control • Analog Test Signal Generator • High Voltage Control and supervision • Probe Sensing • Control of Relay Board • Temperature Sensing for TEE probes • Step Motor Control for TEE probes • Temperature Sensing for circulated air (System Temperature Surveillance) 5-3-16-2 System Temperature Surveillance The FEC board monitors the temperature in the airflow at the air intake and in the airflow at the air outlet. • If the temperature inside the system (at the air outlet) increases to 60 oC, a “High System Temperature” error will be displayed on the screen. • If the temperature increase to 65 oC, the system will start an automatic shutdown. The temperature will normally be recorded at startup, and then repeated every hour. This frequency will increase if the temperature exceeds the limit. The temperature measurements make it possible to monitor the environmental conditions (temperatures) for the scanner and prevent overheating. The temperature measurements are available in a te mperature log available via the Service Platform. It is also available at D:\log\logfile-temp.txt.
