ELECTRIC LOCO TRAINING CENTRE.

The present edition of TROUBLESHOOTING Directory is prepared in such a wayto make it user-friendly and also to educate the user, on theoretical background ofproblems and solutions. On opening the first page itself the user will know what torefer, to overcome the problem encountered by him. To minimize the time to reachrelevant Chapter/page, the facility of Index Cutting is provided. The explanatorynotes along with the appropriate circuits are given on the left side of theproblems/failures discussed on the right side. This is done so as to educate theDriver on the theoretical background of problems and solutions there off. Though,the TROUBLESHOOTING DIRECTORY is referred by the LOCO PILOTgenerally in case of failure only, the explanatory notes given can be gone through bythe driver in his spare time. Over a period of time, this will enable the LOCOPILOT to become sufficiently familiar with the theoretical aspect of a failure,making him competent to troubleshoot the failure without having to referTROUBLE SHOOTING DIRECTORY at the instant of the failure.

The air brake system is being introduced both in coaching and freight stockon large scale. The problems/failures connected with air brake system are dealt withexclusively and in detail. In addition to the TROUBLESHOOTING, this bookconsists of Operating Instructions and Operation of Multiple Units,problems/failures regarding air brake trains and other instructions.

We sincerely hope that the LOCO PILOTS community will make the best use of theend product of the efforts put in by all of us.

STANDARD INSTRUCTIONS FOR LOCO PILOT AND LC.

1. During trouble shooting in block section, utmost care should be taken to trouble shootthe fault, and resume traction within 20 minutes. If unsuccessful LC/TPC control is tobe informed, for assistance. All efforts should be made to minimize and curtaildetentions in block section.

2. In MU/Consist, if one of the loco fails, try to clear block section, with good loco orgood locos without wasting time for trouble shooting.

3. In case of trouble shooting in MU/Consist locos, the abnormal sign should always bepicked up from leading loco. There after all the observations and interventions shall bemade on the loco which is defective.

4. When ever HOBA is placed in OFF position during trouble shooting in one of the locoin MU/Consist, HOBA of other locos also to be kept in OFF position.

5. While wedging contactors or relays ensure that the auxiliary contacts are fully operatedand contactors do not chatter after wedging.

6. LC should be informed at the normal stoppage regarding wedging of relays/contactors.

a) FOR WEDGING CONTACTORS – Take Complete Safety measures.If C105, C106 & C107 are wedged; Q118 isto be manually operated for closing DJ.After isolating any auxiliary motor throughrotating switch, ensure its correspondingcontactor is properly opened.

b) FOR WEDGING RELAYS - First switch off battery.If relay Q118 is wedged – block sectionmay be cleared observing working of allAuxiliaries.

7.a) During trouble shooting if MPH is isolated, the train can be worked up to thedestination provided MVRH is working normally and there is no appreciable rise in theoil level in the transformer gauge.

The following current rating to be observed.

Starting: 920 amps for 10 minutes.Continuous: 500 amps.

6

The loco should be withdrawn in a planned manner by the LC.

b) In case MVRH is isolated – Put HC105 on ‘0’,if HC105 is not provided Wedge Q118,clear block section with the following current rating.

Starting: 920 amps for 10 minutes.Continuous 500 amps.

c) In case MVSL is isolated – Clear block section with the current rating of 500 Amps.

8. During trouble shooting if HOBA/HQOP is kept OFF or HQOA is on 0, a frequentwatch should be kept for any smoke emission from power equipments i.e. RSI blocks,TMs, BA panel and auxiliaries etc. as the case may be. LC should be informed beforestarting the train. LC should withdraw the loco with HQOP/HOBA in off or HQOA on 0in a planned manner and direct the loco to the nearest shed for attention.

9. Whenever any equipment (including TM)/relay are isolated on a locomotive, loco pilotmust record in the loco log book and inform LC at the first available opportunity.LC mustensure planned withdrawal of the loco from service.

10. Driver must record all cases of on line loco troubles/other unusual occurrences/ wheelslipping, clearly mentioning the time loss in block section/station, time and place ofoccurrence as well as information given to LC.11. Whenever HPAR is placed in “0” position during trouble shooting in one of the locoin MU/Consist, HPAR of other locos also to be kept in “0” position.

12. Check availability/working of following safety equipments.

NOTE : 1. In MU Manual Control of GR on Trailing Loco is not permitted.

43

2. In MU/Consist operation while working with EEC, Whenever the GR isbrought to 'O' by BPR — bring MP to 'O'. Before progressing — put MPagain On 'N'3. After wedging a relay observe safety precautions as mentioned in pageno.

Precautions on RELAY wedging

When relay Q-50 is wedged:

1. Ensure the correct setting of J-1 and J-2as per the direction and CTF 1-2-3 ontraction side (↑), C-145 fully opened position before wedging Q-50.

2. Do not operate MPJ till the train reaches the relief point.

3. When DJ is tripped on notches keep MP on '0' for GR to regress to '0'.

When relay Q-51 is wedged (or HPAR on ‘0’):1. Relay Q-51 should be wedged in de-energised position.

2. Wedge should be inserted between pallet and core.

3. Auto regression will not take place during wheel slip or QD or Q20 action

takes place or when relay QRS de-energised.

4. Operate sanders o avoid wheel slip. Observe LSP and ammeters for wheel slipindication.

5. Observe BP pressure and vacuum level, to avoid QRS de-energised

6. Check the relay for any over heating. If the relay is over heated, trip DJ, remove thewedge and contact TLC for advice.

When QRS Relay is wedged:

1. Watch and ensure BP pressure and vacuum is adequate and the train is runningsafely.

2. Whenever the train is parted, immediately keep MP on '0' and bring GR to 0 '0'.

3. When RS is opened and A-9 is brought to emergency, keep MP on '0'.

When Q 100 Relay is wedged:

1. Before opening DJ, open all auxiliary switches,

2. After closing DJ, close one by one auxiliary switches with a time gap of 5 seconds

44

to avoid overload on ARNO.

3. If DJ trips then before closing DJ, bring MP to ‘0’,MPJ to ‘0’ and put HBA ‘OFF’then energise the LOCO as per procedure, otherwise ICDJ will experienced.

When Q 118 Relay is wedged or HOBA is kept in OFF position:

1. Check the working of all auxiliaries frequently whose interlocks are provided in Q118branches. i.e., MVRH, MVMT1, MVMT2, MPH, MVSL1, MVSL2.

2. If any auxiliary does not work (or smoke emission found), then open DJ and lower pantoimmediately and take precautionary measures.

When Q 45 Relay is wedged:

1. Against regular practice on Neutral Section before arriving “close DJ” board do not close

BLDJ.

2. Frequently check the working of MVSI1, MVSI2.

3. Bring MP to ‘O’ and open DJ if found LOW/NO tension on line, so frequently watch ‘UA’

in driving desk.

4. Observe smoke emission from Q30 and RQ30

5. Observe OHE voltage on UA.

When No-tension on line remains for a long time, then remove the wedge of Q45 to avoidchattering sound of Q44, Q118.Precautions after wedging QSVM.

1. BLVMT should be switched on before closing DJ.

2. BLCP should be switched on after 5 seconds of SIV rams up full voltage. (SIV ON LED

glows or LSCHBA extinguishes)

Precautions after wedging QTD101.BLCP/BLCPD should be switched on after 5 seconds of SIV rams up full voltage. (SIV ON LEDglows or LSCHBA extinguishes)

When loco pilot closes DJ leading loco ARNO will start after 3.5 secs. Andstarting time of SIV loco is approximately 6 seconds.As and when BLVMT willswitch ‘ON’ the trailing loco,which is SIV,the SIV will switch ‘OFF’ and after 2

84

seconds of delay,the SIV will start again and take complete 8 seconds time to fullvoltage.

In this condition,if loco pilot takes notches beyond 5th notch,the DJ of trailingloco will trip as the air flow relay of QVMT-1 or QVMT-2 or QVRH are not pickedup.The loco pilot shall be counseled to start taking notches only after extinguishing ofthe LSCHBA indication .

(ii) SIV loco leading and ARNO loco trailingThe instruction to loco pilot for SIV loco ,before closing DJ BLVMT switchshould be ‘ON’ for soft start.In this condition ,when DJ closes the SIV locoblower motor starts with soft start mode and ARNO loco’s blower I;e MVRH,MVMT-1 &MVMT-2 will start after closing Q100 relay.

While working MU locos locopilots shall be advised:-(i) To release the BLRDJ switch as per the practice being followed in the

case of ARNO fitted locomotives,irrespective of one or other locomotiveis fitted wih ARNO or SIV.

(ii) To start taking notches only after extinguishing of the LSCHBA indicationto ensure that loco with SIV does not trip through air flow relays.

MICROPROCESSOR BASED LOCO

TROUBLE SHOOTING

ICDJ:

1. Check Add. CCBA, CCBA, CCPT & CCCPU. If any fuse melts, renew the same. If again fuse

melts, keep HOBA in OFF and renew the fuse.

2. Ensure MR/RS pressure is above 8Kg/cm2.

3. Check safety relay target, if any relay energized, act according to TSD.

4. Ensure BA voltage is above 90 Volts.

5. Ensure GR on ‘0’

6. Try to close DJ with BP2DJ.

7. Keep HQOP 1 in OFF, HQOP 2 in OFF, and HOBA in OFF and try.

8. Try from rear cab.

9. Keep HBA on ‘0’, wait for 3 minutes and try to energise the locomotive.

10. In ARNO provided locos check C118 contactor closing or not.

TLTE:

1. If LSB glowing ensure J1, J2 and CTFs are in proper position.

2. Ensure SMGR pressure is between 2.5 to 3.5Kg/cm 2.

3. Ensure RGEB 2 COC is in open condition.

4. Try with EEC operation.

5. Try from rear cab.

6. Keep HOBA in OFF and try.

Try to clear the section by manual operation of GR.At times, the fault diagnostic systems

are giving erratic information leading to wrong guidance since they are not stabilized fully.

Hence Loco Pilots should follow the normal procedure of troubleshooting.

ANNEXURE-AVIGILANCE CONTROL DEVICE (VCD)

Operating Instructions of VCD for loco pilotDo’s Don’tsAfter BL key is unlocked, check for ‘VCD OK’LED signal on VCD display panel.If thatLED glows it is an indication that VCD in working condition and it is in service.If VCD indicates ‘VCD Fault’ then by pass VCD and record in loco log book.Always keep VCD in service Don’t By pass VCD with out proper reasonAlways keep IP valve in service Don’t close IP Valve Cock.If IP valve is closed

VCD indicates as ‘BP-FED-Fault’ at the time oftest/penalty brake.

Always act in time (<76 secs.)toacknowledge VCD in vigilancecycle(60 secs.)+or flash cycle(8secs.),by any of these methods

a)By any ACK push button orb) Operate any horn switch orc)Operate sanders ord)Notches up/down ore)Brakes applied through A-9

or SA-9

Don’t press ack.push button continuously for morethan 60 sec.It will lead to application of penaltybrake through IP valve with auto regression.

Note: 1.If brakes are applied by loco pilot through A-9 or SA-9 there is no need toacknowledge VCD as it is in vigilance suppression mode.

2. When BL key is unlocked VCD will apply test brake as soon as BP pressurereaches 4.5 kg/cm2 to check whether the IP valve is in service or not

Penalty brake : If VCD is not acknowledged during the above period, it applies penaltybrake for 30 secs. through IP Valve with auto regressionProcedure to Release Brake : After extinguish of yellow flashing LEDs on VCDdisplay panel, keep MP in ‘0’ position and press any VCD ack pueh button switch torelease brakes.Bypass VCD :If VCD indicates”VCDFault” on its display panel or behaves erraticallythan bypass VCD and record in log book.How to Bypass : VCD bypass switch is available only in VCD master on its right side.Brake and open the seal & remove cover to access bypass switch and put it to ‘off’.
