5.2 Voltage Reconnection Procedure

Note:
®
For Decision-Maker 3000 Controllers with software versions before 2.8, go to the next Section.
Press the generator set master control OFF/RESET button
1. Turn the controller pushbutton/rotary selector dial until it stops at the Volt Select menu. See Figure 55
Note:
If the Volt Select menu does not appear, the controller voltage selection feature was not activated using SiteTech™
software.

2. Press the selector dial and the voltage selection option (second line on the display) will start to flash.
3. Turn the selector dial clockwise or counterclockwise until the desired voltage selection option appears.
4. Press the selector dial. The second line on the display will stop flashing and the new voltage will appear.
5. Rotate the generator set voltage selector switch (if equipped) to match the desired voltage shown on the controller
display. Skip steps 7-9 and go to step 10.
If the generator set does not have a voltage selection switch, continue to step 7
6. Disconnect the generator set engine starting battery, negative (-) lead first. Disconnect power to the battery charger
(if equipped).
7. Use the figure titled: 20-150 kW Permanent Magnet Single-Phase Alternators, ADV-5875U-1, figure titled: 20-300 kW
Permanent Magnet Alternators, ADV-5875U-2, or figure titled: 300 kW and Larger Pilot-Excited, Permanent Magnet
4M/5M/7M/10M Alternators, ADV-5875U-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.
8. Reconnect the battery, negative lead last.
9. Press the generator set master control RUN button to start the generator set. Check the digital display for correct
voltages using the section titled: Generator Metering (and Calibration).
10. Press the generator set master control OFF/RESET button to stop the generator set after completing the voltage
adjustments.
