WORKING OF THE PANEL :
-> AUTO MODE
When the supply fails, the 'Mains supply failure Monitor' operates after preset time of approx. 10 Secs. This actuates the '3 impulse Engine Start' control unit The Control Unit gives three starting impulses with an interval of 1-5 Secs, if the engine starts at the first impulse , this unit shuts off. If not , it gives further two impulses during which time, if the engine does not start, the unit shuts off, activating the audio-visual alarm for 'Set Fails to Start'. On Starting of the engine, the alternator switch gear closes automatically after the preset time of 1-10 Secs. When the Mains Supply is restored , the 'Restoration Timer' operates and after the preset time of 10 Secs., the load is automatically transferred to the Mains, and the Generator shuts down.
Â
-> TEST MODE
By operating the 'AMF Test' Push Button, the conditions of Mains Failure are stimulated as explained in the Auto Mode above, without disturbing the supply through mains Switchgear.
-> MANUAL MODE
The DG Set operates as a standard manual operated set , and all its functions are carried out manually by means of 'Engine Start/Stop' and 'Alternator Contactor ON/OFF' Push Buttons.
