We have thyripart pilot excitaiton & AVR system installed for our Siemens make 1FC1 type synchronous generator (Black start diesel generator).
The thyripart AVR system is having TBS 505 thyristor module and RBS 505 Z1 controller module.
I am in need of information/ method to start the generator with avr in manual control mode OR change the avr control to manual mode during generator in loaded condition.
