Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
areinplace.

WARNING
Testing the voltage regulator. Hazardous voltage can
cause severe injuryor death. High voltage ispresent atthe
voltageregulator heat sink. Topreventelectrical shock donot
touch the voltage regulatorheat sink whentesting the voltage
regulator.
(PowerBoostt, 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 PowerBoostV (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.
