does not change the mode in the controller(s).
After starting the genset(s) and checking the AC wiring:
1. To verify that the generator is running, check that the genset engine LED (1) on the display unit is green.
2. To make sure that the voltage and frequency is OK, check that the genset voltage LED (2) on the display unit is green.
3. Turn the function selector to
Generator synchronisation
. This forces the genset(s) to make a dynamic synchronisation to the
mains. The synchronisation is shown on the display unit screen. When the genset(s) are synchronised, the controller(s)
automatically close the generator breaker(s). When the first genset's generator breaker is closed, the breaker LED (3) is green.
4. The genset(s) run with a minimum of load while waiting for the next step.
NOTE
The minimum load is adjusted in parameter 7023. The default is 5% of the nominal power.
