6.
Check the status of all control and auxiliary inputs and the appropriate LEDs on the front foil of the unit.
Check the status of all control and auxiliary outputs as well as the setting of the controller outputs.
7.
Synchronizing
the power circuit breaker:
a)
Open the power circuit breaker.
b) Ensure
the reference voltage that the system has to synchronize to is within the permissible limits.
c)
Energize terminal 3 "Enable CB".
d) If the generator voltage is 50 % lower than the rated value, the voltage controller starts to operate. Con-
figure the controller parameters so that the set point value is efficiently controlled.
e) Prior to the automatic closing of the circuit breaker, ensure that all measuring values have been wired
and applied correctly. At the synchronous point, verify if the synchronizing functions have been con-
figured correctly. It is recommended that a differential voltage meter be used for this test at the power
circuit breaker connection.
8.
Dead bus start
a)
Open the power circuit breaker.
b) Verify all conditions and measuring voltages are correct and test the close breaker command.
c) The power circuit breaker should close automatically.
9.
After successfully closing the power circuit breaker the "Gen CB - ON" LED must illuminate
.
