This screen shows the firmware instruction set revision for
the EUs display microprocessor.
This screen shows the number of Battery Packs reporting
that their voltage level has reached the proper float
voltage.
This screen shows the UPSs battery voltage. The accuracy
of this measurement is ±5% of the full scale value of
68Vdc.
This screen shows the cause of the last transfer to on-
battery operation. This information is updated each time
the UPS transfers to on-battery.
If the UPS transferred to on-battery operation because
of a mains voltage notch or spike, the display reports the
cause as notch/spike.
If the UPS transferred to on-battery operation because
of an unacceptable rate of change in the output voltage,
the display reports the cause as dV/dt.
If the UPS transferred to on-battery operation to
maintain proper output voltage regulation in response to
high or low mains voltage, the display reports the cause
as HiLineV or LoLineV.
If the UPS transferred to on-battery operation to
conduct battery tests, the display reports the cause as Self
test.
This screen shows the rms current drawn by the UPSs
load in Amps. The accuracy of this measurement is ±5% of
the full scale value of 35 Amps.
This screen shows the Volt-Amps drawn by the UPS's load
as a percent of full rated capacity. The accuracy of this
measurement is ±5% of the full scale value of 105%.
