No-Load Voltage Adjustment: BeG 6.5KW
1.
Remove the louvered metal plate covering the terminal connections and the capacitor (see page 61).
2.
Start the generator and allow
tt
to
run for approximately five minutes so the engine can warm up. Make
sure the generator
is
operating without any equipment drawing AC current from the generator (that
is,
shut OFF all electrical appliances). Make sure the engine's speed (Hertz) is correct. Adjust the governor
as needed
to
obtain the correct engine speed before proceeding.
3.
Referring to the AC load connections diagram below, check the generator's no-load voltage
by
measur-
ing the voltage across the neutral lead and the hot lead with a volt meter. Make sure
you
record this read-
ing. The generator's no-load voltage
is
115 - 124 volts at 60.5 - 61.5 Hertz. If the voltage output is higher
or
lower than specified, proceed.

Shut off the generator. Make sure the correct Hertz lead
(60
Hertz
#6,
or
50
Hertz
#5)
is plugged into the
capacitor. Refer
to
the illustration on the
top
of
the next page.
~WARNINGI
DO NOT attempt
to
make a no-load voltage adjustment while the generator is operating. The
capacitor can hold a
450
volt charge. Touching any wiring can result in a severe electrical
shock.
In addition, attempting
to
make a no-load voltage adjustment while the generator is
operating can cause fingers
to
be caught
in
the generator's rotor.
5. Refer
to
the illustrations on the next page before making any adjustments. Note that there are three plugs
grouped for the right capacitor terminal,
#7,
#8, and #9. If the generator's no-load voltage
is
low, then
disconnect the
lower numbered plug and connect the plug with the next higher number. If the generator's
no-load voltage is high, then disconnect the higher numbered plug and connect the plug with the next
lower number. Note that the plug presently
connected
to
this terminal may be
anyone
of
the three plugs
available.
6. If the generator's no-load voltage cannot be adjusted because the voltage needs to be increased and the
highest numbered
plug is already connected
to
the right terminal, or the voltage needs
to
be lowered and
the lowest
numbered plug
is
connected, then follow the steps listed at the bottom
of
the next page. Ask
your
local Westerbeke dealer for a BC GENERAL TROUBLESHOOTING GUIDE before performing the
steps listed at the bottom
01
the next page.
NOTE: Make sure the insulating covers on the unused leads are in place and are not
in
con-
tact with each other
or
in contact with the generator's housing.
