Tender Invited for 630 KVA Diesel Generator set by Director FRI ...

AUTOMATIC MAINS FAILURE PANEL : SEQUENCE LOGICFollowing sequence logic should be followed while designing the logic forAMF Panel:1.Automatic starting of diesel generating set in the event of mains voltage belowpreset value / total failure.2.On restoration of mains supply, it's quality will be monitored for a preset timeand then load is automatically transferred on the mains and diesel engine isshutdown after a preset idle running period.3.In the event of failure of diesel engine to start on failure of mains supply on firstattempt, two more attempts are made automatically. If, engine still fails to start dueto some defect, it will get locked automatically and necessary audiovisual signalshall be given.4.In the manual mode the DG Set can be started by the operator by pressing thestart button and stopped by stop button irrespective of the mains condition.5.In the test-mode, mains failure condition is simulated. However, the load will notbe transferred on the DG Set.
