Decision-Maker 3+ Controller Overvoltage Shutdown Adjustment - Kohler 4EOZ Installation Instructions Manual

Note: Position the current transformers with the
dot or HI side CT marking toward the
generator set.
Note: Only generator sets equipped with AC meter
controllers
breakers require CTs.
5. If the controller has meters, remove the controller
cover and reposition the meter scale lamp jumper
(see Figure 8-6) matching the position of the
desired voltage (shown in Figure 8-5).

139/240-volt (low wye) and 277/480-volt (high
wye), 3-phase, 4-wire, 60 Hz configurations use
different overvoltage shutdown settings than all
other configurations. Recalibrate the overvoltage
shutdown if the reconnection changes the voltage
to or from one of these configurations.
Section 8.3, Decision-Maker
Overvoltage Shutdown Adjustment.
recalibrate the overvoltage adjustment for other
voltage changes.
7. If the controller has meters, set the phase selector
switch to the L1-L2 position (1-phase or 3-phase
configuration depending
connection). Connect a voltmeter across leads L1
and L2 if the controller has no meters.

Note: Equipment damage. Verify that the voltage
ratings of the transfer switch, line circuit
breakers, and other accessories match the
desired line voltage.
8. Reconnect the starting battery, negative (--) lead
last. Place the generator set master switch in the
RUN position to start the generator set. Observe
the voltmeter and verify that the unit has the
desired line voltage connection.
Adjust the voltage using the voltage adjustment
potentiometer on the generator controller front
panel. See Figure 8-7.
9. Stop the generator set after completing the voltage
adjustment.
10. Disconnect the external voltmeter if used. Replace
the controller cover.
