Appendix A: Adjusting Voltage Settings
When the unit is not sounding an alarm, you can use the button shown below to change the
following:
• Nominal Voltage — The normal voltage the UPS is programmed to expect, and the nominal UPS
output voltage under line loss conditions.
• Buck — The input voltage at which the Patriot Pro II decreases voltage before providing output
because the input voltage is too high.
• Boost — The input voltage at which the Patriot Pro II increases voltage before providing output
because the input voltage is too low.
• Transfer to Inverter — The point at which the UPS switches to inverter (battery power), either
because AC input voltage is very low or because it is very high.
Note:
Make sure you want to change these values before you start the procedure below. Once
you press the button shown for 10 seconds, the values will change to the default values,
and any previous changes you have made will be lost. If you have a question, contact
the nearest Best Power office, or call Worldwide Service at 1-800-356-5737 or 1-608-
565-2100.
Do not change voltage settings when unit is operating on
inverter. To change the values, follow these steps:
1.
Press the button shown until the LEDs on the front of the
Patriot Pro II blink. After the LEDs blink, three will stay lit
and the Patriot Pro II will beep for one second.
2.
The LEDs that are lit show which voltage settings are selected. The LEDs are numbered in the
drawing below to help you identify them. Tables 4 and 5 show the voltage settings for each
possible combination of LEDs.
For example, by default, LEDs 2, 3 and 4 will be lit (see
diagram). If your UPS is a U model, you will find this
combination of LEDs in the first row of Table 4. This row
shows the following:
• With 96 volts input or lower, the Patriot Pro II switches
to battery power.
• When input voltage drops to 109, the Patriot Pro II
begins to increase the output voltage.
• 120 is the nominal or expected input voltage.
• When input voltage rises to 130, the Patriot Pro II begins to decrease the output voltage.
• With 146 volts input or higher, the Patriot Pro II switches to battery power.
Press this
button for 10
seconds (until
all of the lights
blink).
