8.4 Voltage Regulator Adjustment
(4--27EFOZ and 5--32EOZ
Models)
Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
are in place.
Moving rotor.
WARNING
Testing the voltage regulator. Hazardous voltage can
cause severe injury or death. High voltage is present at the
voltage regulator heat sink. To prevent electrical shock do not
touch the voltage regulator heat sink when testing the voltage
regulator.
(PowerBoost
t, PowerBoostt III, and PowerBoostt V
voltage regulator models only)
The voltage regulator is typically located in the
controller. Adjustments are possible without removing
the voltage regulator. The voltage regulator adjustment
procedure applies to both the PowerBoost
 IIIE
(Figure 8-11) and PowerBoost
 V (Figure 8-12) voltage
regulators.
Note: Broadrange generator sets. The following
adjustment procedure is for readjustment of the
voltage regulator and governor for broadrange
generator sets with mechanical governors.
Note: Special tool. Frequency meter 50/60 Hz.
Note: Rheostat connection. Connect a
customer-provided rheostat across regulator
leads/terminals 33 and 66 to adjust the generator
output voltage from a location remote from the
generator set. The rheostat (10 kOhms, 1/2 watt
minimum) provides a 5-volt adjustment range.
