Filed: 1998-10-30
Abstract: PURPOSE: A device for controlling the re-operations of cryopumps is provided to select and re-operate the cryopump needing re-operation through controlling switches of re-operation and solenoid valves corresponding to each cryopump for improving productivity by reducing loss time. CONSTITUTION: A controller(10) of vacuum in a beam line or a controller(20) of vacuum in end station outputs a re-operation signal to re-operation switches(32,42,52) of a first, a second and a third controllers(30,40,50) of re-operation. Then, the re-operation switches are turned on or off in response to the selective signals(S1,S2,S3) of re-operation. Herein, if a cryopump controlled by the first controller of re-operation re-operates, the selective signal S1 is enabled. Also, if the cryopump controlled by a first or a third controller of re-operation re-operates, the selective signal S2 or S3 is enabled. Therefore, the re-operation of the cryopump is decided by the switching operation of the re-operation switch in response to the selective signal of re-operation for selectively re-operating the cryopump needing re-operation.
