Be GENERATOR SINGLE PHASE
NOTE:
WESTERBEKE recommends that the following generator tests
and adjustments be performed by a qualified technician.
50Hz
LEAD
DUAL EXCITER CIRCUIT MODEL
These generators have dual Hertz and no-load voltage adjust-
ment connectors at each capacitor. There are five connectors
available for each capacitor. Two connectors are for Hertz
selection, 60 Hertz or 50 Hertz, and three connectors, #7, #8,
and #9, are for no-load voltage adjusttnent.
When making Hertz change or no-load voltage adjusttnents
proceed as follows:
1. Shut the generator down.
2. Select the appropriate Hertz connection to plug into each
capacitor #60, 60 Hertz, 1800 RPM or #50 Hertz, 1500
RPM. The three other connectors at each capacitor, #7,
#8, and #9, will have an effect on the no-load voltage
produced by the generator. One connector from each
group can be plugged into each capacitor. No-load voltage
will increase or decrease approximately 8 - 10 volts
between connectors used in any pair combination to
achieve the prescribed no-load voltages illustrationed
above.

WARNING:
Make certain the insulating covers on
the unused leads are in place and are NOT in contact
with each other
or
in contact with the generator's

NOTE:
Simply cross the capacitor's two tenninals with an
insulated )plastic handle) screwdriver. This will discharge
any excess electricity.
NOTE:
When changing Hertz produced by the generator, an
engine speed adjustment at the governor must be made. The
AC output connections on the terminal blocks must be
selected for the voltage and Hertz to be produced. The Hertz
plug connection at the capacitor must be changed for 50
Hertz (#5) or 60 Hertz (#6). Theframe ground wire must be
moved when changing from 115 volts, 50 Hertz to 230 volts,
50 Hertz

WARNING:
Capacitors must be discharged before
handling as they store electricity and can pack a
potentially lethal charge even when disconnected from
their power sourr:e.
