故障现象在行下肢DSA检查时,检查床不能按设定的程序完整运行。即可以从A点运行到B点,但无法从B点返回到A点。同时不能曝光。故障检修(1)查看错误日志,没有任何有价值的信息。(2)重装系统软件(排除软件系统引起的故障),故障现象同上。(3)将检查床下系统的往返总线(电缆线)重新排布(排除电缆线交错引起的故障),故障现象同上。(4)重新连接床下的所有插头(排除插头连接松动引起的故障),故障现象同上。(5)检查和测量所有的RT总线电缆,均正常。(6)查看原理图(图1),有3个RT信号(RT 3、RT 9和
Symptom In the lower leg DSA inspection, the examination bed can not be fully run according to the set procedure. That is, it can run from point A to point B, but can not return to point A from point B. At the same time can not be exposed. Troubleshooting (1) View the error log, there is no any valuable information. (2) reinstall the system software (excluding software system caused the fault), the same phenomenon as the fault. (3) Check the bed system under the bus (cable) to re-arrange (excluding the staggered cable caused the fault), the same failure phenomenon. (4) Reconnect all the plugs under the bed (trouble caused by loosening of the plug connection), the same as above. (5) Check and measure all RT bus cables, all normal. (6) View the schematic (Figure 1) with 3 RT signals (RT 3, RT 9 and
