The Voltage Regulator Average Voltage Adjustment
can be adjusted if the DC output voltage of the 6VSG
generator is desired to track to a value other than the
nameplate rating. If the output voltage is changed, the
output current limiting should be recalibrated to the
new output current rating. The output current rating is
computed as: 6000 / Voltage Regulator Average
Voltage Adjustment. This current rating is also listed in
SiteTech.
The Voltage Regulator Average Adjustment (VRAA)
allows for the generator to operate at an output voltage
that is different than the default setting. For example,
to set the 6VSG-54V to run at 58V, change this VRAA
setting to 58.0. See Figure 3-7.
Note: The protective trip points are based on the
system voltage; therefore, changing the VRAA
will not shift the protective trip points. Adjusting
system voltage value to 58V will shift the
protective trip points up, but will result in a slow
ramp up from default output of 54V to desired
58V each time the VSG starts.
Note: Depending on the system and the application,
adjustments may need to be made to both the
VRAA and the system voltage settings.
Note: The current limit does not change. The current
limit is based on the circuit breaker on the VSG
for each system.
The Voltage Regulator Average Voltage Adjustment
requires Kohler SiteTech to change.
