Compound electrical circuits blocks with a train diagram are carried out with plug connectors of the ShR type installed on block Ш, located under the control panel in the middle part. There is also block P, on which resistors of semiconductor-switching lamps are installed, to ensure noise immunity. The driver's controller 1 KU.04O with a reversible handle is installed in front of the driver on the console. To the left of the controller is block K with the main switches for controlling the movement of the train. On the K block there are switches: to turn on the power of the doors, to control the pantograph, "Release the brakes", "Restore protection", "Disable explosives", "Sandboxes", traction (CT), "Start SIO" (SSZ-I systems), as well as toggle switches for switching on lighting and cockpit.

FOREWORD
The book contains general information about electric trains alternating current ED9M, ED9T and ER9P. The issues of their formation, devices, operation of electrical circuits and some malfunctions of electrical equipment are considered.
The manual is compiled on the basis of an electric train of the ED9M series produced by the Demikhovsky Machine-Building Plant, with an indication of the differences from electric trains of other series and indices and a description of their individual main units.
The manual is intended primarily for use by locomotive crews of electric trains, as well as by repair personnel of multiple-unit depots. The manual will also be useful for students of technical schools, lyceums and universities with a railway specialization.
This manual is not an educational publication and can only be used as an introductory material with general information about alternating current electric trains.
Unlike previous editions, this manual has been supplemented color illustrations of the described devices.
In connection with the constant work to improve electric trains, aimed at increasing their reliability and traffic safety, minor changes may be made to the design of electric trains that are not reflected in this publication. These changes will be reflected in subsequent editions.

Experimental ten-car electric train ED9T-0001 was manufactured by OJSC “Demikhovsky machine-building plant” (OJSC “DMZ”) in September 1995. Electric equipment of SJSC “Riga Electric Machine-Building Plant” (SJSC “REZ”), AO “Estel Pluss” (St. Tallinn), Zaporozhye Transformer Plant. The technical documentation for the electric train was developed by the department of the chief designer of OJSC “DMZ”.

Electric trains ED9T and ER9T produced by SJSC "Riga Carriage Works" are practically identical in mechanical and electrical parts. The new train does not have a PVKT system (axial equalization of traction coefficients). At the same time, the following new technical solutions, systems and equipment were applied on the ED9T electric train:
The main feature of the ED9T-0001 electric train is the use new system regulation in the mode of rheostat braking. In this system, in braking mode, the TD armatures are connected in two circuits. The braking controller switches the resistors and provides seven steps of rheostat braking. At the 12th position, the electro-pneumatic braking is activated.
The TD excitation in the braking mode is performed from section 0 - 4 of the traction winding of the power transformer through a semi-controllable bridge, which allows regulating the TD excitation current.
The driver's controller (KM) has four braking positions. In the first and second positions, rheostatic braking with reduced effort is carried out. In the third position of the KM, rheostat braking is carried out with a normal setting. In the fourth position of KM, electric braking of motor cars is supplemented by electro-pneumatic braking of trailed and head cars.
The rheostat braking control system SURT regulates the currents of the TD armatures in the rheostat braking mode at different values \u200b\u200bof the braking resistor stages and maintains the TD excitation current constant when the set value is reached.
The electric train scheme provides for three stages of protection during skidding and skidding: discrete wheelset slip control devices; skewing relays (RB), responding to the voltage difference across the TD collectors; relay boxing relay (RRB), turning off the traction and electric braking modes when the voltage difference across the TD collectors exceeds 706 ± 50 V.
Discrete wheelset slip control devices (DUKS) are installed on all electric train cars. One set includes four axial speed pulse transducers mounted on all axles of the car, a logic block and four electro-pneumatic dump valves connected to the brake cylinders.
In October-November 1995, after a control run of 5,000 km without passengers at the Gorky-Moskovsky depot on the Gorkovskaya road, on the experimental ring of VNIIZhT, acceptance traction and energy tests were carried out, the purpose of which was to determine the main indicators of the electric train and assess their compliance with regulatory and technical documents operability and efficiency of its electrical systems in design and emergency modes of movement, testing of protection systems for traction electrical equipment in emergency modes. The tests included:
In mid-December 1995, the electric train was put into operation at the Irkutsk-Sortirovochny depot of the East Siberian road.
The set of electrical equipment developed for ED9T was also supplied by RER JSC to RVZ for installation on ER9TM electric trains. Until now, these electric trains have been supplied only to Belarus.
