MORE ABOUT AXLE DETECTORS (CEL SSDAC)

 1)  We know that in CEL SSDAC, there are two TX coils , one 21 KHz and another 23 KHz.

2)   Similarly there are two RX coils,  one 21 KHz and another 23 KHz

3)  From Each coil , two conductors are coming out and their color are Red and Black.

4) Between these two conductors, we can measure the Resistance with our Multimeter. This value is Coil Resistance of this coil.

5) Before measuring Coil Resistance,  open the link of both conductors from ARA terminal.Then only you will get correct value.

6) For TX Coils ,Resistance of these coils  must be less than 1 ohm. If you are not getting this value, replace TX Coil,it will give you failures.

7) For RX Coils, Resistance of these coils must be between 2 ohm and 3 ohm.

8) After measuring Coil Resistance. terminate these conductors on ARA Terminals as mentioned in below picture.


9)     When we measure voltage  at  TX 1 or TX 2 ,it will come between (30 V- 40 V ) AC.

10)    When we measure voltage  at  RX 1 or RX 2 ,it will come between (275 m V - 600 m V)  AC.

11)    When we measure frequency at TX 1 or RX 1.it will come around 21 KHz

12)   When we measure frequency at TX 2 or RX 2.it will come around 23 KHz .

CRS , CST and PCE sanction

  Validity of CST sanction   is six months .Required when we are doing any changes in existing interlocking.e.g commissioning of BPAC Validity of CRS and PCE sanction are same (01 year). PCE sanction is required only for closing the LC gate.Earlier it was with CRS, now delegated to PCE. ESP,SIP,SWRD,PD and SWR required to be attached with PCE sanction.  CRS sanction is must when do any change in interlocking,e.g.any new line is opened. Validity of CRS sanction is 01 year. CRS permission is required in following cases. a) Additions/extensions or alterations to the existing block, Signalling and interlocking installations b) Change in Block, Signalling and Interlocking installations. c) New stations temporary or permanent. d) Interlocking of level crossings, catch siding and slip sidings etc. CST Sanction   CST Sanction required in following works 1) Provision of Telephone at already Manned level crossings. 2) Provision of electrical & mechanical lifting barrier including emergency

Catch Siding and Slip Siding

  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
