Operation
BUCK VOLT
(Sets the high UPS buck-mode activation voltage for overvoltage
correction)
Notes:
• Specify BUCK VOLT activation setting for AVR buck-mode operation
(default = 128V AC).
• Buck mode automatically deactivates as the input voltage recovers to the BUCK VOLT -
HIGH GAP value. (Default = 128V AC - 5V AC = 123V AC.)
•
SENSE TYPE:
Enables configuration of UPS AC power sensing to maximize
UPS operation for standard line power AC and generator power applications.
To configure, navigate via LCD panel to the SENSE TYPE screen and select the
desired input power configuration to the UPS or GENERATOR (default) setting.
Selection options include:
UPS
(UPS is configured for standard AC line power)
GENERATOR
(UPS is configured for generator power applications)
•
BAT TEMP COMP:
Enables configuration of UPS BATTERY TEMPERATURE
COMPENSATION-related float voltage reduction during high temperature
conditions in mV/°C/Cell units. To configure, navigate via LCD panel to the BAT
TEMP COMP screen and select the desired temperature compensation value.
Selection options include:
REDUCE BY -2.5mV
REDUCE BY -3.0mV
(default value)
REDUCE BY -3.5mV
REDUCE BY -4.0mV
•
EXT. FAN:
Enables configuration of EXTERNAL FAN activation temperature.
To configure, navigate via LCD to the EXT. FAN screen and select the desired
temperature for the external fan to turn on (default = 25C).
Third SETTINGS Screen (4 selections)
•
BAT LOW VOLT:
Enables configuration of BATTERY LOW VOLTAGE for notification
that batteries are nearly depleted as the UPS is running in battery mode. To
configure, navigate via LCD to the BAT LOW VOLT screen and select the desired
low-battery voltage setting.
SMART1548ET
selection options are 42.0 to 55.0V DC (default value is 46V DC)
SMART1524ET
selection options are 21 TO 27.5V DC (default value is 23V DC)
•
CHARGER:
Enables configuration of CHARGER CURRENT. To configure, navigate
via LCD to the CHARGER I screen and select the desired maximum charging
current. Selection options are: 2 AMP, 4 AMP, 6 AMP, 8 AMP and 10 AMP
(default = 2AMP).
