Since 2011 electric multiple unit (EMU) trains of ED4M series, produced by "Demikhovo machinery plant", have been equipped with the on-board health monitoring system COMPACS®-EXPRESS-3. Currently the plant has produced more than 60 EMU trains, equipped with the system.
Three-year operating experience of EMU-trains, equipped with the on-board system, allows to ascertain a high efficiency of the systems operation within detection of malfunctions and incipient defects in mechanical equipment, electric circuits, traction electric motors and auxiliary machines, as well as in compressed-air and electric compressed-air brake equipment.
Within EMU-trains commissioning the system is widely used by adjusters of "Demikhovo machinery plant" JSC in order to reveal and eliminate mounting errors, as well as for control of the main equipment operating parameters during testing.
Thus, during commissioning of EMU-train ED4M-0434 the system has detected a substantial increase of a traction motor current in 043404 car within the train traction movement on the 4th position of a principal controller. The received data has helped to eliminate the shortcut in the field reduction circuit, as well as to avoid the traction electric motor overload consequences.
MDRS system is a right hand for adjusters’ crews within EMU-trains commissioning on the plant test area and multiple unit depots.
COMPACS®-EXPRESS-3 system is a serious step towards processing efficiency and safety of "Demikhovo machinery plant" JSC production.
