Dual Exciter Voltage Adjustment - Westerbeke 5.0Kw BCDR Operator's Manual

5.0KW Be GENERATOR SINGLE PHASE
DUAL EXCITER NO-LOAD VOLTAGE ADJUSTMENT
These generators have dual Hertz and no-load voltage adjust-
ment connectors at each capacitor. There are five connectors
available for each capacitor. 1\vo connectors are for Hertz
selection, 60 Hertz or 50 Hertz, and three connectors, #7, #8,
and #9, are for no-load voltage adjustment.
When making Hertz change or no-load voltage adjustments
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, #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 4 - 6 AC volts
between connectors used in any pair combination to
achieve tbe-prescribed no-load voltage as illustrated below.

NOTE:
When changing Hertz produced by the generator, an
engine speed adjustment at the throttle arm linkage 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). Thejrame ground wire
must be nwved when changing from 115 volts, 50 Hertz to
230 volts, 50 Hertz.
A
WARNING:
Capacitors must be discharged before
handling as they store electricity and can pack
a
poten-
tia//y lethal charge even when disconnected from their
power source.
NOTE:
Simply cross the capacitor's two terminaLs with an
insulated (plastic handle) screwdriver. This will discharge
any excess electricity.
