Reconnection Procedure (Microprocessor Controller Only) - Kohler 6.5RMY Operation Manual

Reconnection Procedure
(Microprocessor Controller only)
1. Place the generator set master switch in the
OFF/RESET position.
2. Disconnect engine starting battery, negative (--)
lead first. Disconnect power to battery charger (if
equipped).
3. Select desired voltage connection from Figure 5-6.
Route leads through current transformers and
connect according to the diagram for desired
phase and voltage.
NOTE
Position current transformers CT1 and CT2
(single-phase) or
(three-phase) with dot or HI mark toward generator
set. Current transformers are only used on
generator sets equipped with metered controllers.
NOTE
Equipment Damage! Verify that transfer switch,
line circuit breakers, and any other accessories
using line voltage are sized for the voltage
selected.
NOTE
See generator service manual for information on
changing generator frequency.
4. If controller is equipped with meters, remove
controller cover and reposition meter scale lamp
jumper, if necessary, to match meter scale lamps
with desired voltage. See Figure 5-8.
5. The jumper J1 must be in place on the overvoltage
circuit board if the generator set is connected for
139/240 or 277/480 volts (3-phase, 4-wire, 60 Hz) if
the generator set is equipped with the overvoltage
kit.

CT1, CT2, and CT3
For all other voltages, remove J1 jumper from the
overvoltage circuit board. See Figure 5-7 for J1
jumper location on the overvoltage circuit board.
6. If the controller is equipped with meters, turn the
phase selector switch to the L1-L2 position
(1-phase or 3-phase depending on generator
connection). If the controller is not equipped with
meters, connect a voltmeter across leads L1 and
L2.
7. Reconnect generator set engine starting battery,
negative (--) lead last.
8. Place the generator master switch in the RUN
position to start the generator set.
9. Check voltmeter for correct voltage.
voltage if necessary with the voltage adjustment
potentiometer on the controller front panel. See
Figure 5-9.
10. Stop generator set after adjustment procedure.
