Interfaces between the controller and alternator assembly
D
using rotor field leads, auxiliary power windings, and
optic board leads.
Allows the Decision-Makerr controller the ability to
D
control a wound-field alternator using the same control
signal as the Fast Responset alternator.
Permits the generator set controller to control the current
D
to the exciter field of a wound-field excited alternator.
Contains two isolated relay driver outputs (RDO) rated at
D
250 mA. Provides RDO outputs indicating a field over-
excitation condition and that the alternator is supplying
voltage to the activator.
