Connection between Rx Coils and SSDAC unit

In this blog you will learn how Rx coils are connected to SSDAC unit (CEL)

1) Rx coil 21 KHz is connected to SCC 1 and Rx coil 23 KHz is connected to SCC 2.

3) These coils are connected through MS Coupler (MS 2).

4) MS 2 coupler is connected behind SSDAC Unit.There are four conductors in MS 2. 

5) Color of these four conductors are Violet,  Violet,   White and  White.

6) Violet and Violet are connected to RX 21 in Location Box.

7) White and White are connected to RX 23 in Location Box.

        By using this color coding you can easily identify the ARA Terminal of Rx coils in the Location Box and trace your failure in short duration.

You will get (275 mV to 600 mV) at the ARA terminal of both Rx 21 and Rx 23 in Location Box.

  Catch Siding is provided to protect the station section, if the gradient is steeper than 1 in 80 falling towards the station section. Slip Siding is provided to protect block section if the gradient is steeper than 1 in 100 towards Block Section. Normal permissible gradient for Block Section is 1:1200 and for Station Section is 1:400. Reception of Trains in Catch Siding Stations- (a) Either a minimum of two Stop Signals shall be provided in rear of the Catch Siding points or the First Stop Signal shall be at an adequate distance equal to Block overlap from the catch siding points. (b) A train shall first be brought to a stop at the First Stop Signal, before the Catch Siding points are set for the main line and the reception signals shall not be taken 'OFF' unless the following conditions are satisfied. (1) The line on which the train is to be received is clear and the train is to be received on the main line.  (ii) The points leading to the Catch Siding as well as all the Poi
