مهندس بترولEmergency diesel generator can be manually started and the generator circuit breaker 52/2C on EUB closed by following the sequence:
Force opening of the diesel engine fire dampers
Check auxiliary voltage to UCP E-002 from Diesel engine batteries is available.
Put selector switch S15B.1 (Alternator excitation) on UCP E-002 in “AUTOMATIC” position.
Set the selector switch S18.3 “EDG OPERATION” at the EDG control panel (UCP E-002) to “BLACK START” position that will override the ESD trip commands.

Press the “START” button of genset control card EASYGEN 3200 to start the generator (softkey ❾)
When the generator is running at 50Hz and the voltage is constant at 380V (see this information on display of genset control card) the genset circuit breaker 52/2C on EUB can be closed to energize the busbars of EUB-000-3-1. To achieve the above, the selector SBS on EUB panel shall be set to EDG position in order to make the 220Vac control voltage available to EUB panel.
Press “CLOSING” push-button on genset control card EASYGEN 3200 to close the genset circuit breaker (softkey ❿or ⓫).
Genset control panel (UCP E-002) closes genset circuit breaker 52/2C on EUB on dead bus, with direct command.
