OPERATIONAL ANALYSIS

OPERATIONAL DESCRIPTION (CONTINUED)

7.The A6060 circuit board controls all functions of the generator, i.e.:

a.Engine DC control system

b.Stepper motor operation

(1)If voltage is low, the board will signal a STEPPER MOTOR to change engine throt- tle setting and increase speed until the desired voltage level is reached.

(2)If voltage goes high, the board will signal the STEPPER MOTOR to reduce engine throttle setting until the desired voltage level is obtained.

c.Output signals for operation of inverter.
