QRSI-1 tripped Action to be taken
a) Check for any smoke, burning smell, flash/weld or any abnormality in
RSI-1, SL-1, L1, L2, L3 J1, CTF-1, QD1 (in BA1 panel), TM 1, 2, 3, U1, U2, A3 and SJ CTF2 in BA2 panel, CTF3, Q20 in BA3 panel. If everything is normal reset the relay target and accelerate gradually, duly watching ammeters. If anything found abnormal, try to isolate the same, otherwise contact TLC for further instructions.
b) If QRSI-1 trips after long Interval, check the equipment as mentioned above.
c) If everything is normal, reset the relay target and resume traction.
d) If QRSI-1 is tripping frequently, inform TLC, check the equipment as mentioned above. If there is no abnormality, isolate TM 1, reset relay, close DJ and resume traction. If QRSI-1 tripped again isolate TM2 and TM3 one by one and try. If QRSI-1 is not tripping when HMCS-1in 2or 3or4, continue traction with that traction motor in isolated condition and work with 5/6th of maximum permissible load.
e) If QRSI-1 is dropping in all positions of HMCS-1, normalize HMCS1 and place HVSI1, HVMT-1 and HVSL-1 on 0. Resume traction with 50% of the maximum permissible load with normal current rating. If load does not permit contact TLC.
NOTE: In WAP-4 (without RB) and WAM-4 6P locos C145, ATFEX and CTFs are not provided.
In WAG-7 and WAP-4 (with RB) locos C145 and ATFEX are connected in RSI-2 circuit.
L1 to L6 are provided in BA3 panel in WAG5 loco
