1.17.3 Activator Board GM88453
(13- 32EKOZD/11- 28EFKOZD
Models)
D Interfaces between the controller and alternator assembly
using rotor field leads, auxiliary power windings, and
optic board leads.
D Allows the Decision-Makerr controller the ability to
control a wound-field alternator using the same control
signal as the Fast Responset alternator.
D Permits the generator set controller to control the current
to the exciter field of a wound-field excited alternator.
D Contains two isolated relay driver outputs (RDO) rated at
250 mA. Provides RDO outputs indicating a field over-
excitation condition and that the alternator is supplying
voltage to the activator.
