Monitor synchroscope status menu.
a. Verify action of synchronizer.
NOTE
If using Process 4–20 mA input, set Process Reference to proper level.
10. After generator breaker closes to the mains, monitor Generator Status
screen.
a. Monitor kW load on unit.
b. Monitor kVAR/PF on unit.

As set by reactive load control setting.
11. Adjust load control gain, stability, and derivative for stable load control.
12. Once satisfied with load control operation, switch to process control (if
applicable).
13. Confirm ramp to process reference level.
a. Tune process control for best response.
14. Remove run with load input to unit.
a. Verify unload ramping.
b. Verify unload trip point.
c. Verify generator breaker opens.
d. Verify cooldown timer (if reached).
15. Set crank repeats, base load reference, process reference, load ramp
times, and load control mode as required for proper operation.
This concludes the Mains Parallel Master Setup.

Set unit for LOM on mains under frequency.
Set Check Mains Breaker = disabled.
Set Dead Bus Closing = enabled.
Remove mains PT and mains CB Aux input by opening mains breaker if
necessary.
Start unit with auto switch input.
Unit will start and close generator breaker to bus.
a. Verify dead bus closing.
b. Apply load to unit using load bank or plant load as applies.
c. Calibrate CT readings if needed.
If in a multi unit system, repeat previous steps for all units. Set all units to be
tested synchronizers to check mode prior to start.
The unit currently on the bus carrying the load will act as a synchronizing
reference for the other units.
Verify voltage matching, phase relationships of additional units by
monitoring the synchroscope status menu.
a. Verify voltage levels across generator breakers.
Tune individual synchronizer dynamics.
a. Calibrate synchronizer if needed.
Once satisfied with each synchronizers operation, shut down these units by
removing the auto input.
Change synch mode settings to run on all units.
a. This will enable generator breaker closure to live bus.
Start one unit in auto and allow it to close to the dead bus.
a. Verify isochronous operation.
b. Verify correct voltage level on bus.
