Operation
• AVR FEATURE: Enables configuration of AVR / AUTO-VOLTAGE REGULATION
to correct undervoltage and overvoltage conditions. Undervoltage Correction
(BOOST) and Overvoltage Correction (BUCK) functions can be enabled and
disabled independently of each other. To configure, navigate via LCD panel to the
BUCK and BOOST screens and select ENABLE/DISABLE for each from the sub-
menu list. Selection options include:
BOOST (Select to ENABLE/DISABLE brownout boost protection)
BUCK (Select to ENABLE/DISABLE overvoltage buck protection)
• LINE QUALIFY: Enables configuration of the amount of time the UPS monitors
line power quality for stability before switching to LINE POWER MODE as AC
power is restored. To configure, navigate via LCD panel to the LINE QUALIFY
screen and select the desired time duration from the sub-menu list (default
value = 30 SEC.). Selection options include:
3 SEC. (UPS returns to line-power mode after 3 seconds of valid AC input)
10 SEC. (UPS returns to line-power mode after 10 seconds of valid AC input)
30 SEC. (UPS returns to line-power mode after 30 seconds of valid AC input)
Second SETTINGS Screen (4 selections)
• LINE DETECTION: Enables configuration of the switchover voltages between
AC and BATTERY modes, plus AVR activation voltages for AVR BOOST and AVR
CUT operation. To configure, navigate via LCD to the LINE DETECT screen and
select the desired transfer voltage points for each of the six conditions. Selection
options include:
LINE HIGH (Sets the high UPS transfer voltage from line-power mode to battery
mode)
Note: Specify LINE HIGH switchover voltage via LCD (default = 152V AC).
LINE LOW (Sets the low UPS transfer voltage from line-power mode to battery
mode)
Note: Specify LINE LOW switchover voltage via LCD (default = 88V AC).
HIGH GAP (Sets the threshold voltage used to calculate the transition from
battery-power mode back to line-power mode. Default = 5V AC.)
LOW GAP (Sets the threshold voltage used to calculate the transition from
battery-power mode back to line-power mode. Default = 5V AC.)
BOOST VOLT (Sets the low UPS boost-mode activation voltage for undervoltage
correction)
Notes:
• Specify BOOST VOLT activation setting for AVR boost mode operation
(default = 102V AC).
• Boost mode automatically deactivates as the input voltage recovers to the BOOST VOLT
+ LOW GAP value. (Default = 102V AC + 5V AC = 107V AC.)
