Abstract:Objective To provide reference experience for maintenance engineers, the main contactor CON A interlock circuit of
Elekta Synergy medical electronic linac was analyzed, the conditions of the main contactor CON A were explained, and the possible
causes and diagnosis methods of the MAIN CON A interlock fault were introduced. Methods When the control software reported
the MAIN CON A interlock fault, the state of main contactor CON A could be checked in the maintenance mode first, and then the
main interlock circuit of contactor CON A could be analyzed, and the corresponding measuring point could be measured by voltmeter
to find out the fault location and analyze the fault cause. Results If the open circuit occurred between two test points, that means
the fault located between the two test points. Conclusion Base on the fault phenomenon, the troubleshooting of the MAIN CON A
interlock fault can be successfully completed by theory analysis and practical measurement.
