[en] New possibilities of the modernized installation YuMO due to automation of separate units are shown. Main unique devices due to modernization are presented. Advantages of the upgraded spectrometer are shown. The basic approaches to creation of control systems by executive mechanisms of spectrometers on the basis of their unification and standardization are formulated. Circuits of the block of management by step-by-step engines, the switchboard-amplifier of step-by-step motors, the circuit of the system of stabilization of the period and phase of the chopper, and the block diagram of the control system of executive mechanisms of the spectrometer YuMO are submitted. Main technical parameters of the basic original mechanical devices are given. (author)
