Optional voltage Regulator
An optional solid-state voltage regulator
(board
:jj:
34410)
is available
for use with the 9 KW BTG generator.
When installed, and the regulation
switch is moved to the ELEC position,
the
regulator works together
with the standard compound transformer regulator to regulate generator
vol tage output.
Installation
1.
The regulator is mounted using existing tapped holes in generator
case.
Use (2) M4 x 0.7-mm screws, 15 rom long, with lock washers,
to mount the regulator board.
2.
Connect the 6-prong generator plug to the receptacle on the regu-
lator board.
NOTE:
The plug is keyed to engage the regulator receptacle
in one direction.
Check this and insert correctly.
3.
Before moving
the
selector
switch
to ELEC,
ensure
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.
4.
With generator no-load voltage properly adjusted, move the selec-
tor
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).
Generator 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 generator frequency:
1.
Connect
the
AC
output
leads
to
the
AC
terminal
block,
following the illustrations on the preceding page.
2.
Adjust
the
engine
speed
to obtain
the
frequency
corresponding
to the voltage selected.
Engine
speed
is
increased or
decreased by adjusting
the belt-
dr iven
governor.
(See
Governor
and
Governor
Adj ustment
paragraph under ENGINE ADJUSTMENT, later in this manual.)
3.
Adjust
no-load
voltage
output
to
corresponding
frequency,
as
explained in earlier paragraph, No-Load Voltage Adjustment.
