Kohler Marine Generator Sets 11EFOZ/13EOZ - Manual (Page 79)

TP-6069 6/03 69 Section 8 Reconnection/Adjustments
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 and/or safeguard circuit
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).

6. The overvoltage shutdown is standard on
Decision-Maker
t 3+
controllers. The
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.
See
Section 8.3, Decision-Maker 3+ Controller,
Overvoltage Shutdown Adjustment. Do not
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 on generator set
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.

Disconnecting the electrical load. Hazardous voltage can
cause severe injury or death. Disconnect the generator set
from the load by opening the line circuit breaker or by
disconnecting the generator set output leads from the transfer
switch and heavily taping the ends of the leads. High voltage
transferred to the load during testing may cause personal
injury and equipment damage. Do not use the safeguard
circuit breaker in place of the line circuit breaker.
The
safeguard circuit breaker does not disconnect the generator
set from the load.
