AC VOLTAGE REGULATOR (CURRENT MODELS)
#054596
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
Ajumper 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 performed using the adjustment on the belt
driven mechanical governor.

VOLTAGE SENSING
AC VOLTAGE
REGULATOR
#054596
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.
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.
UNDER FREQUENCY
The UNDER FREQUENCY potentiometer on the regulator
can not be adjusted in the field. The control
ECU is
monitoring engine speed and will react to stop the unit
should engine speed fall below a preset level.
The UNDER FREQUENCY circuit in the regulator can be
a cause
of voltage/light flicker in a new regulator. If this
occurs, tum the potentiometer counter clockwise 5-6 turns
to arrest this.
EXCITER WINDING
Proper polarity in this circuit must be maintained. Black to
- Ex and red to+ Ex. Failure to do so may damage the
regulator.
AUXILIARY WINDING
Connect the correct color wires to the terminals. Green or
gray to Aux L and blue and brown to Aux N.
Exciting the generator 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 should not be operating. Remove the- Ex and + Ex.
electrical connections off the regulator.
2. Maintaining polarity. Connect the
+ (plus) from a 9 volt dry cell
battery to the
+.Ex (red I electrical lead coming from the generator
and
the- (negative) to the- Ex (Black electrical lead coming
from the generator.
3. Start the generator and observe the reaction and voltage output
froin the generator and react accordingly. ~ ', ~
