Shore Power Transfer Switch - Westerbeke 8.0KW - 60Hz Operator's Manual

BT GENERATOR SINGLE PHASE
OPTIONAL AUTOMATIC VOLTAGE REGULATOR (AVR)
BT 6 STUD MODELS ONLY
An
optional solid-state voltage regulator (board #34410)
is available for use with the BT series generators. When
installed, and the regulation switch is moved to the ELEC
position, the regulator works together
wi~
the standard com-
pound transformer regulator to regulate the generator's volt-
age 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
I. The regulator is mounted using existing tapped holes in
the generator's case. Use two (2) M4" 0 7mm screws,
each 15mm long, with lock washers to mount the regula-
tor board.
2. Connect the 6-prong generator plug to the receptacle on
the regulator board.
NOTE:
The plug
is
keyed to engage the regulatorreceptacle 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 selection switch into the ELEC position. Adjust
the regulator hoard potentiometer to set NO-Load voltage
at 120 - 122 volts at 61.5 - 62.0 Hertz (230 - 234 volts at
51.5 - 52.0 Hertz). The regulator board is operating in par-
allel with the compound transformer and should maintain
voltage output within
±5
per cent from NO-Load
to
FULL-Load.
NOTE:
Do not use the regulator to force NO-Load voltage
down. Use the compound transformer for this junction. Using
the regulator to peiform this causes the. regulator to use more
exciter circuit power. This leaves less exciter circuit power
for loaded conditions.
SwHching Shore Power to Generator Power
A
CAUTION: Heary motor leads should be shut
oft
before switching shore power to generator power or
vice-versa because voltage surges Induced
by
swltcb-
ing with beary AC loads on the vessel being operated
may cause damage to the exciter circuit components in
the generator.

If the installer connects shore power to the vessel's AC cir-
cuit, this must be done by 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 sbore power and generator output are connected
at
the same time. This type of generator damage is not
covered undel tbe warranty; It is the installel's respon-
sibility to make sUle all AC connections are correct.
