Optional Voltage Regulator
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
with the standard compound transformer regulator
to
regulate the generator's voltage output. In the
ELEC mode, the regulator excitation to the group I exciter windings, and the transformer 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 x 0.7
rum
screws, each
15
mm long, with lock washers to mount the regulator board.
2.
Connect 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
ELEC, ensure that the no-load voltage produced
by
the generator
is
properly adjusted. The no-load voltage desired with the selector switch in the COMP position must be
slightly lower than the voltage desired with the regulator in the circuit.
(i.e. 120 volts 60 Hertz no-load voltage in COMP 116 -
118
volts for 50 Hertz 216 - 218 volts.)
4.
With the no-load voltage adjusted in COMP move the selector switch
to
ELEC position. Adjust the
regulator potentiometer
to
bring the no-load voltage up
to
120
volts at
60
Hertz and 220 volts at 50 Hertz.
The potentiometer adjustment must not be used
to
force the no-load voltage down.

Frequency
is
a direct result
of
engine/generator speed:

To
change the generator's frequency, refer to the "Maintenance and Adjustments" section
of
this manual.
Load Connections
The generator's data plate gives the voltage, current and frequency rating
of
the generator. An
AC
wiring
decal is affixed to the inside
of
the louvered cover on the generator end. A diagram
of
the various
AC
voltage connections
is
provided on the decal. The information on the decal
is
similar to the figure shown
on the following page.
