BT GENERATOR SINGLE PHASE
OPTIONAL AUTOMATIC VOLTAGE REGULATOR (AVR)
An
optional solid-state voltage regulator (board #34410)
~ is available for use with the BT se~generators. When
instailed, and the regulation switch is moved to the ELEC
position, the regulator works together with the staodard
compound transformer regulator to regulate the generator's
voltage output. In the ELEC mode, the regulator provides
excitation to the group 1 exciter windings, and the trans-
former provides excitation to the group 2 exciter windings.
Installation
1.
The regulator is mounted using existing tapped holes in
the generator's case. Use two (2) M4 x 0.7mm screws,
each 15mm long, with lock washers to mount the
regulator board.
2. Cormect the 6-prong generator plug to the receptacle on
the regulator board.
NOTE:
The plug is keyed to engage the regulator receptacle in
one direction. Check this and insert it correctly.
3. Before moving the selector switch to the ELEC position,
the NO-Load voltage produced by the generator when in
the COMP position will have to be adjusted. The NO-load
voltage should be adjusted down between 114 - 118 volts
(60Hz) or 224 -228 volts (50Hz) following the
procedures as explained earlier in this manual.
4. With the generators no load voltage properly adjusted,
move the selector switch into the ELEC position. Adjust
the regulator board potentiometer to set NO-load voltage
to 120. - 122 volts at 60-60.5 hertz (230-234 volts at
50-50.5 hertz). The regulator board is operating in parallel
with the compound transformer and should maintain
voltage output within + or -5% from No-load to Full-load.
NOTE:
Do not use the regulator to force NO-Load voltage
dnwn. Use the compound transformer for this function. Using
the regulator to perform this causes the regulator to use more
exciter circuitpower. This leaves less exciter circuit power
for loaded conditions.
NOTE:
Ship to shore switches are available at your
WESTERBEKE dealer.
A
CAUTION: Heavy motor leads should be shut
off before switching shore power to generator power
or vice-versa because voltage surges induced by
switching with heavy AC loads on the vessel being
operated may cause danage to the exciter circuit
components in the generator.

meanS of the Shore Power
Transfer Switch. Set the transfer switch shown in the
diagrams to the OFF position. This switch prevents
simultaneous connection of shore power to generator output.
A
CAUTION: Damage to the generator can result if
utility shore power and generator output are connected
at the same time. This type of generator damage is not
covered under the warranty; it is the installer's respon-
sibility to make sure all AC connections are correct.
