Propulsion Control Circuit
To move the locomotive, supply of Traction Alternator is send to traction motor through Power contactor, BKT, Reverser. This circuit is design to pickup above electro pneumatic contactor as and when require. In this circuit as per speed of locomotive two combination of traction motor are changed and during dynamic brakes traction motor convert into generator. Traction motor has following combination:
a) Series Parallel combination
b) Parallel combination
Reverser Contactor Control – To move the locomotive, keep reverser handle in desired direction, put ON GFCO-1&2 and on opening master handle reverser contactor coil will energize as per working control stand
