Power supply and data processing device of УПОИ type is manufactured in a metallic enclosure, with Exdial Mb explosion protection marking, two cable glands of M40*1,5 type and mechanic lever for on/off switching.
The УПОИ device enclosure has two sections. In the upper section there is the terminal board installed used to connect the apparatus power supply unit as well as terminal boards required to connect the intrinsically safe circuits to the rope road train driver’s control panel (ПМКД) or train driver’s indication panel (ПИМ). In the second section there are intrinsically safe power supply units and control blocks. The rope road train driver’s control panel (ПМКД) is manufactured in a metallic enclosure, with ExiaI Ma explosion protection marking. On the right side of the ПМКД there are cable glands of M16*1,5; M32*1,5 and M40*1,5 types. The rope road train driver’s control panel has four opening sections: two ones at the front side of the enclosure and two ones — at the back side. Three sections of the ПМКД are closed, plumbed and have the control blocks installed in them. In the forth section there are the terminals required to connect the external circuits.
The train driver’s indication panel (ПИМ) is manufactured in a metallic enclosure, has ExiaI Ma explosion protection marking and cable glands of M16*1,5; M20*1,5 and M32*1,5 types. The controlled light signaling unit of ССУ-24 type is manufactured in a plastic enclosure, has ExiaI Ma explosion protection marking and two cable glands of M16*1,5 type. At the front side there are installed two LED indicators: red and green ones.
The sound signaling device of УЗС type is manufactured in a plastic enclosure, has ExiaI Ma explosion protection marking and two cable glands of M16*1,5 type. At both sides of the УЗС enclosure there are piezoelectric radiating devices installed. The voice communication post of ПГС type is manufactured in the enclosure with ExiaI Ma explosion protection marking and has two cable glands of M16*1,5 types. At the front side of the ПГС enclosure there are following elements installed: the dynamic head of the loudspeaker of 0,5ГДШ-2 type, microphone block and «Call» button. The identification block is built into the cablerope switch (ВДШ). This block is a board with wires used to connect to normally-opened contacts of the ВДШ. The speed and direction sensor of ДСН type is manufactured in a metallic enclosure of ExiaI Ma explosion protection marking, with a cable gland of M20*1,5 type. Inside the enclosure there is a terminal used to connect to the ПМКД and two inductive sensors.
The linear receiver of ЛП type is manufactured in the enclosure of ExiaI Ma explosion protection marking, with two cable glands of M16*1,5 type. Inside the enclosure there is a terminal used for connections. The end load of KH type is manufactured in the enclosure of ExiaI Ma explosion protection marking, with two cable glands of M16*1,5 type. Inside the enclosure there is a terminal used for connections. The monitoring device is manufactured in the electro-technical cabinet with cable glands of M16*1,5 type. Inside the cabinet there are terminals used to connect both data transmitting line and power supply network. Mobile conductor’s control panel is manufactured in a still enclosure of ExiaI Ma explosion protection marking. On the bottom side of the enclosure there are cable glands of M16*1,5 type. At the front panel of the enclosure there are control and communication elements installed. Inside the enclosure there are a radiocommunication unit and terminal blocks used for connecting mobile antenna and battery pack.
Accumulator power supply unit is manufactured in a plastic enclosure of ExiaIC Ma explosion protection marking. The enclosure is equipped with a handhold for easy carrying. Under the handhold there are installed the indicators of the accumulator battery charge state and the unit operation state. On the sides of the unit there are connectors with locks to connect the power network adapter and the mobile conductor’s control panel. Inside the enclosure there is a potted board with accumulator batteries. The power supply adaptor is manufactured in a metallic enclosure with the network supply cord and two cords with plugs used to connect the accumulator power supply blocks of the radio station. The mobile antenna is a frame that is installed into a plastic enclosure and filled with assembly foam to be hard.
