Kohler Voltage Reconnection Procedure for Advanced Digital Control 2 Generators

5.2Voltage Reconnection Procedure

1.Place the generator set master switch in the OFF/RESET position.

2.Disconnect the generator set engine starting battery, negative (--) lead first. Disconnect power to the battery charger (if equipped).

3.Use Figure 5-1, Figure 5-2, Figure 5-3, or Figure 5-4 to determine the generator set voltage configuration. Note the original voltage and reconnect as needed. Route leads through current transformers (CTs) and connect them according to the diagram for the desired phase and voltage.

Note: Position current transformers CT1, CT2, and CT3 with the dot or HI side CT marking toward the generator set.

4.Reconnect the battery, negative lead last.

5.Go to Menu 14—Programming Mode and select the Program Mode—Local. See Section 2.8.14, Menu 14—Programming Mode, for the complete procedure.

6.Go to Menu 7—Generator System and update the voltage information. See Section 2.8.7, Menu 7— Generator System, for the complete procedure.

7.Go to Menu 12—Calibration and perform the calibration procedure. See Section 2.8.12, Menu 12—Calibration, for the complete procedure.

8.Go to Menu 11—Voltage Regulator and perform the voltage regulator setup procedure. See Section 2.8.11, Menu 11—Voltage Regulator, for the complete procedure.

9.Move the generator set master switch to the RUN position to start the generator set. Check the digital display for correct voltages using Menu 1— Generator Monitoring.

10.Move the generator set master switch to the OFF/RESET position to stop the generator set after completing the voltage adjustments.

11.Replace the controller cover.

12.Place the generator set master switch in the AUTO or RUN position.
