Abstract: This paper described analysis to
malfunction and processing system of external circuit in Diesel Locomotive
Controllers(DLC) applied to Dongfeng 5D locomotives.All the reasons resulting
in malfunction are analyzed and discussed in details.Thus the inspector can be
familiar with the effects of all external circuit of DLC on circuit board,then
determine easily and remove the failures.This system may have a wide
application because rate of failure is reduced greatly and the circuit board is
protected effectively.
