    '. 3ut the switch in manual mode as stated above and check the pressure gauge

    for sufficient oil pressure.

    ). 3pen the valve from accumulator to generator.

    *. !ush the spring loaded valve and the generator should start.

    +. $heck voltage and frequency.

    /. eep the generator running for '-'/ min and check the e0haust temp and other

    parameters.

    1. $heck the sump level.

    4. 2or stopping, use the manual stop button from the panel.

    5. After stopping the generator, pressuri6e the hydraulic accumulator to desired

    pressure.

    7. $lose the valve from accumulator to generator.

     

    Procedure for Automatic Start

    '. 2or automatic start, we know that there is a breaker which connects Emergency

    #witch 8oard "E#8% and 9ain #witch 8oard "9#8%: and there is also an interlock

    provided due to which the emergency generator and 9ain power of the ship

    cannot be supplied together.

    ). Therefore, we simulate by opening the breaker from the tie line, which can be

    done from the 9#8 or the E#8 panel.

    *. After opening the breaker, the emergency generator starts automatically with the

    help of batteries and will supply essential power to machinery and pumps

    connected to E#8.

    +. 2or stopping the generator, the breaker is closed again and due to the interlock

    the generator becomes off load.

    /. ;ow again put the switch to manual mode to stop the generator.

    1. !ress stop and the generator will stop.
