REGULATOR
#046446
VOLTAGE
POTENTIOMETER
The
output voltage
of
the generator can be adjusted using the
potentiometer with the generator running at its selected speed
(frequency)
by
turning the adjustment until the desired
voltage is obtained.
NOTE:
If
the
voltage
is
set higher than
selected rated
voltage,
the
generator
may
be
damaged.\
FREQUENCY
A
jumper
on
the regulator is connected to two
of
the three
pins for either
60 hertz or 50 hertz operation.
NOTE:
This
does not automatically
change
the
engine
speed.
Engine
speed change
is
peiformed
using
the
adjustment
on
the
belt
driven mechanical
governor.
STABILITY
If
at no-load or while under load with steady engine speed,
AC
output voltage fluctuation is experienced. Adjust the
stability potentiometer. This modulates the reaction time
of
the regulator to external inputs, thereby eliminating any
instability in the AC generator load system.
UNDER
FREQUENCY
With the generator running at rated speed and producing
desired voltage, reduce the engine speed using the
mechanical governor by 4 hertz. Adjust the under frequency
potentiometer until the AC output voltage
of
the generator
starts to drop. Then restore the engine speed to the original
rated speed.
VOLTAGE
SENSING
The voltage sensing connections are 0 and
115
when selected
output voltage is between
1
OOV
and
140V.
Connect between
0 and
230
when selected output voltage is between 200V
and280V.

Proper polarity in
this
circuit
must
be
maintained.

EXCITING
THE
GENERATOR
Exciting the geuerator using an external DC source can ,be performed
when troubleshooting a generator/AC.voltage output issue.
The
following procedure should be followed:
1.
The generator shouW not be operating. Remove the
F-
and F +
electrical connections
~ff
the regulator.
2.
Maintainmg polarity. Connect
th~
+{plus) from a 9 volt dry cell
battery to the
red
electrical lead coming from the generator and
the-
(negative) to the
F-
white electrical lead coming from the
generator.
3. Start the generator and observe the reaction and voltage output
from
the generator and react accordingly.
The.
troubleshooting booklet for the
BE
style generator will help you
determine the cause
of
a generator AC voltage output issue
by
the
AC voltage found
being produced
by
the generator and the reaction
of
the generation to excitation.
