Begin Spec B Run Mode
When the engine starts, release the Start/Stop switch and it will return to the center Run position. The following events
occur:
• Control assembly (A1) opens the circuit to the start solenoid (K1), which opens the circuit to the starter motor
(M1) to stop cranking. Control assembly (A1) also opens the field flash circuit to AVR pin 7.
• 50 Hz models only: Voltage from the battery, used to power the control assembly (A1) and the fuel pump (E2),
is replaced with output voltage from the generator charge winding B1-B2. (Refer to
Battery Charge Mode
on
page 6-24.)
• The control assembly senses output voltage from L1 (X1 50-Hertz) for the start disconnect function.
• Remote run output is energized through the control assembly (A1) to power the time meter, battery condition
meter and run lamp in the optional remote control .
• Voltage from the generator Q1-Q2 winding provides power to the voltage regulator VR1 to use for supplying field
current to the generator. (Refer to
Generator AC Output Mode
on page 6-30.)
