G343 INDUSTRIAL ENGINE Caterpillar

Single Unit Operation

Usage:

Final adjustments for a new installation are given here.

1. Remove the exciter regulator cover and loosen the locknuts on the voltage level, voltage droop and regulator gain controls.

2. Turn the voltage droop control counterclockwise to zero droop and tighten the locknut.

VOLTAGE ADJUSTMENT CONTROLS

1. Voltage Droop

2. Voltage Level

3. Voltage Gain

3. Run the engine at full governed speed.

4. Using the voltage level control, adjust the open circuit (no load) voltage to equal nameplate voltage.

5. Apply rated load and adjust the governor control for rated speed.

6. Adjust the regulator gain control until the line voltage is equal to rated voltage at rated load.

7. Allow the electric set to operate about one hour until temperature in the generator has stabilized.

8. Repeat steps 4, 5 and 6.

9. Tighten the locknuts on the voltage level and regulator gain controls, and install the exciter-regulator assembly access cover.

The electric set is now properly adjusted for single unit operation.
