This Brush Pas Model 510 has been obsolete long long time ago and no longer in production line. This including their support service which is not exist already.
The function of auto synchronizer in plant is to synchronize generator output to the grid system.

Auto synchronizer provide precise synchronization of generator (s) to a power system.
BRUSH is one of the models in the market for auto sync. Anyway the parts, warranty, system support from them is no more exist?! The production of this model has been stopped and no more produce including support on the system itself.
