Symbols, Leds And Audible Beeps - Best Power Fortress 750 Guia Del Usuario

Symbols, LEDs and Audible Beeps

The front panel LEDs and an audible beep indicate the UPS status. The UPS beeps whenever it
is on battery power or an alarm is present. See Table 2 for information on beep coding.
In the figure below, bucking means that Fortress is reducing high input voltage, and boosting
means Fortress is increasing low input voltage.
Steady: Fortress is operating on AC line.
AC Line Operation:
A, B, C, and D indicate
per cent of full load.
A, B, C, & D, with D
flashing, load = 110%
or higher.
A, B, C, & D = 75-100%
A, B, & C = 50-75%
A & B = 25-50%
A = 0-25%

Battery operation:
A, B, C, and D indicate
battery charge.
A, B, C & D = 75-100 %
B, C & D = 50-75 %
C & D = 25-50 %
D = 0-25 %; when D
is flashing, less than 2
minutes of runtime
remain.
Steady: Acceptable input power is present. The unit is
running on line power.
Off: No input power is present or the unit is switched off.
Blinking: The unit is boosting or bucking utility power.
Boost = Automatically increases low input power to prevent
the unit from switching to battery.
Buck = Automatically decreases high input power to prevent
the unit from switching to battery.
The unit is running on battery power.
Output Overload: Refer to Tables 2 and 3.
Replace the Battery or UPS Fault. Refer to Tables 2 and 3.

Blinking: Fortress is bucking or
boosting input AC line.
D
C = UPS shutdown due to output overload.
C
B = UPS failed the battery test.
B
B & C = UPS shutdown from communication
at RS-232, remote shutdown or SNMP.
A
A & B = UPS shutdown due to main relay
failure or short circuit on output.
A & C = UPS over-temperature shut down.
A = UPS Fault; Fan Fail or Overcharge
