2.During startup, printed circuit board action controls the START/ STOP RELAY to deliver battery voltage to the ROTOR, via the brushes and slip rings.

a.The battery voltage is called “Field Boost”.

b.Flow of direct current through the ROTOR increases the strength of the magnetic field above that of “residual” magnetism alone.

3.“Residual” plus “Field Boost” magnetism induces a voltage into the Stator excitation (DPE), battery charge and AC Power wind- ings.

4.Excitation winding unregulated AC output is delivered to an electronic Voltage Regulator, via an Excitation Circuit Breaker.

a.A “Reference” voltage has been preset into the Voltage Regulator.

b.An “Actual” (“sensing”) voltage is delivered to the Voltage Regulator via sensing leads from the Stator AC power windings.

c.The Regulator “compares” the actual (sens- ing) voltage to its pre-set reference voltage.

(1)If the actual (sensing) voltage is great- er than the pre-set reference voltage, the Regulator will decrease the regulated cur- rent flow to the Rotor.

(2)If the actual (sensing) voltage is less than the pre-set reference voltage, the Regulator will increase the regulated current flow to the Rotor.

(3)In the manner described, the Regulator maintains an actual (sensing) voltage that is equal to the pre-set reference voltage.

NOTE: The Voltage Regulator also changes the Stator excitation windings alternating current (AC) output to direct current (DC).

5.When an electrical load is connected across the Stator power windings, the circuit is completed and an electrical current will flow.

6.The Rotor's magnetic field also induces a voltage into the Stator battery charge windings.

a.Battery charge winding AC output is deliv- ered to the battery charge rectifiers (BCR) which changes the AC to direct current (DC).

b.The rectified DC is then delivered to the units battery and battery charge outlet, to maintain the battery in a charged state.
