the Station Master on duty to operate any DG sets in case of failure of local supply by pressing the push button concerned due to any reason
the DG set will be operated by the contractor‟s operator. For this purpose the contractor has to depute a D.G. operator round the clock at each
station. The contractor‟s operator available at the station will have to start one of D.G. Set on instruction by the station Master Concerned. The
contractor operator will ensure that the DG set work alternatively at 6 hours interval.
The Contractor‟s operator will also be responsible for routine Maintenance of D.G. Sets installed at different stations as well as the controlled
panel and batteries provided for functioning of self starting drive of D.G. Set. For this he will be required to check the fuel feed, lubricant,
Temperature, output voltage, output current, electrolyte level of the batteries provided for the self starting mechanism. He will maintain the
logbook for routine inspection of these items as per the Performa to be given by the Railway representative. The contractor‟s operator will also
maintain separately for each DG Set with record of consumption of fuel and lubricant in the Performa given by the Railway representative. In
case of failure of any DG set at any station, the contractor‟s operator will immediately stop the concerned DG set and start the other D.G. set.
There after the contractor will arrange for immediate rectification of the fault, if it is Minor in nature i.e. all the faults excluding seizure of engine
and burning of coil of alternator. He will also be the responsible to immediately inform the ASM on duty about the failure and nature of failure of
that particular DG set.
NOTE:
Deleted.
At any time the number of stations LC gates where the DG set are to be operated may vary from – NIL.

distilled water, Grease, Sulphuric Acid, Meters, indication bulbs, etc. will be provided by the contractor.
The contractor‟s operator will ensure that the self starting system of DG set functions smoothly, so that the ASM on duty can put on the generator by
the operating the remote push button when ever supply from State Electricity Board goes off. However, incase of failure of self-starting system, the
contractor operator‟s will manually start the D.G. sets and ensure the early rectification of the fault itself starting system.
