in normal circumstance the batteries are stby with load switch open and charging switch closed.this position held by electro magnetic coil against pressure on the spring.loss of main power has the effect of decharging the coil.so that the load switch moved to closed the circuit by spring pressure.so circuit is now closed and supply to starting motor via battery and emcy generator will start.

Hi Guys,

I would like to draw your attention to a very particular question.

” If the Main Switchboard becomes dead, there is no 24V supply available either as the batteries are flat and Emergency Generator does not start automatically. Now Emergency Generator can be started manually but how the Emergency Generator can then be connected to Emergency Switchboard ?? ”

Please note there is no 24V supply available which runs the controls on Emergency Switchboard.

Dear Jhayskie, recently My Ship have Problem regarding E’Cy Generator that Unable take place when Balck Out test. FYI My E’cy Generator can start Automaticaly and Hz, Voltage showing normal ( Power present in the Line ) when BlackOut but the Problem is the E’cy ACB unable to close or connected to the Main Line. Would you like give some help to rectify it??? Or Any One ?

Regulation for emerg generator. What is the time it should come on load when power fails off

In reply to Jumbo iritamuno. @jumbo: There is an option of "Simulation" which be activated by pulling a fuse in the autostart panel which supplies the under-voltage or under-frequency relay. The emergency generator can be tested even when the main supply is active.

How may emergency generator be tested on full load with main running and supplying

If the second means is also batteries, it’s acceptable or not.

Hey guys,i leave some important matters about those questions that raise by some friends out there.
First and foremost, if power outrage prevailed obcourse interlocking device that connected both ESB &MSB will activate. In ESB there is BUS TIE ACB once during sense voltage breakdown it send signal to UVT for this reason other electrical components activated relay and timers that trigger to start the engine after 28 seconds. Engine started established voltage 440vac and frequency at 60hz about 40-45 seconds ESB ACB closing to line. Once the Diesel generator run and retrieve normally the power management system will follow and automatically activate the interlocking device at BUS TIE AIR CIRCUIT BREAKER thus emergency generator to stop additioally depending in the program if auto or manually stop the engine.

You can possibly test this scenario by switching sequencial test: Engine (without load)/ Engine&Acb(with load and power blockout arise)..

God bless all..

How it starts automatically ? What mechanism is used to sense that the voltage has dropped so the em. Gen should start?

In reply to Koshal. @Koshal: The emergency generators switchboard is provided with this mode so that it can be used during laytime in port for the supply of the ship mains.
