Single Exciter Model - Westerbeke 5.5 EGCD Operator's Manual

BC GENERATOR SINGLE PHASE
NOTE:
WESTERBEKE recommends that the following generator tests
and adjustments be performed by a qualified technician.
SINGLE EXCITER NO-LOAD VOLTAGE ADJUSTMENT
1.
Remove the louvered metal plate, at the back of the
generator, covering the AC terminal connections and
the capacitor(s).
2. Start the generator and allow it 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. Refer to the DC Wiring Diagram for the ECU P8
connection change.
3. Referring to the AC load connections diagram below,
check the generator's no-load voltage by measuring the
voltage across the neutral lead and the hot lead with a volt
meter. Make sure you record this reading. 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.

4. Shut off the generator. Make sure the correct Hertz lead
(60 Hertz
#6,
or 50 Hertz #5) is plugged into the ·
capacitor(s).
A
WARNING:
Capacitors must be discharged before
handling as they store· electricity and can pack a poten-
tially _lethal· charge even when disconnected from their
power source.
NOTE: Simply cross the capacitor's two tenninals with an
insulated (plastic handle) screwdriver. This will discharge
any·excess electricity.
A
WARNING:
Do not attempt to make a no-load volt·
age adjustment while the generator Is operating. The
capacitor can produce a 400·500 volt charge. Touching
any wiring can produce a severe electrical shock. In
addition, attempting to make a no-load voltage adjust-
ment while the generator Is operating could cause your
lingers to be caught in the generator's rotor.
5.
There are tln·ee plugs grouped for the right capacitor ter-
minal, #7, #8, and
#9. If the generator's no-load voltage is
low, then disconnect the lower numbered plug and con-
nect the plug with the next higher number. If the genera-
tor'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
tenninal may be any one of'the three plugs available.
6. · H 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 num-
bered p1ug is connected, refer to the WESTERBEKE BC
Genefator Troubleshooting Guide).
A
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
housing.
