Conversion From Older Shunt-Wound Voltage
Regulation to Modern Solid-State Voltage Regulation
It is possible to use the XR5C Universal Voltage regulator with older Shunt-Wound
exciters that originally had manual, mechanical, or series solid-state voltage regulators
by converting the wiring as in the diagrams below. If the generator will not build up after
conversion, try switching your F+ and F- leads at the regulator and try starting up again.
NOTE:
Armature brushes
MUST BE ISOLATED
from the field leads for
proper operation!
