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 provides excitation
to
the
group
1 exciter windings, and the transformer 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 0.7 -mm
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, with the
selector in COMP position,
by
following the procedures
for
"No-Load Voltage
Adjustment," page 33.
4.
With the generator's no-load voltage properly adjusted, move the selector switch into the ELEC position.
Adjust the
regulator board potentiometer
to
set no-load voltage at 120 Volts, 61.5 - 62 Hertz (110 Volts,
51.5 - 52 Hertz). The generator's voltage output should be within
±5
percent from no-load
to
full-load.
Generator
Frequency
Frequency is a direct result
of
engine/generator speed:
1800
RPM
- 60 Hertz
1500
RPM
- 50 Hertz
To
change the generator's frequency, refer
to
the "MAINTENANCE AND ADJUSTMENTS" section
of
this
manual, page 48.
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 volt-
age connections is provided on the decal. The information on the decal is similar
to
the figure shown on the
following page.
The generator is a
single-phase, reconnectable 120 Volts AC two-wire
or
120/240 Volts AC three-wire, at 60
Hertz;
or
110 Volts AC two-wire, 110/220 Volts AC three-wire,
or
220 Volts AC two-wire, at 50 Hertz. Refer
to
the "SYSTEM SPECIFICATIONS" section
of
this manual
for
ratings, page 5.
