3.3 Main Menu Screen
The Main Menu screen allows the operator to access many
displays to monitor the operating performance of Galaxy
4000, obtain alarm information, change operational settings
as well as issue software based commands.
The Main Menu conveniently displays groups of items
according to function. By using one of the first two soft keys
the selection cursor may be moved up and down until the
desired display group is selected. Then by pressing the
fourth soft key, the selected display (or display group) will
be summoned. See Figure 3-5.
3.4 Measurements
Selecting the Measurements option from the main menu
provides the following screen selections: battery, power,
current, voltage, frequency measurements, and ratios.
3.4.1 Battery Measurements Screen
The Battery Measurements screen provides a rapid
assessment of the available battery voltage, current,
battery charge, temperature as well as expected service
life. See Figure 3-6.
The backup time measurement will be calculated if the
following battery parameter identification (BPI) require-
ments are met:
Required Conditions to Initiate BPI:
◗ BPI set to automatic in personalization.
◗ Battery charge level = 100%.
◗ UPS On-line (Inverter Coupled).
◗ Mains 2 within tolerance.
◗ Percent load is >15%.
◗ Battery temperature 0-40°C (32-104°F).
◗ No battery faults.
◗ No rectifier or inverter overload condition.
If the above conditions are met and maintained then the UPS will run a successful BPI. A normal BPI will drain the
batteries to a level of 80% capacity. When the BPI is completed successfully, the backup time will be displayed when
the batteries are 100% charged. If the load does not change by more than ±20%, then a BPI will be run again in one
year. Another BPI will run only if, the load changes by ±20% or the BPI is a year old.
If one of the conditions below occurs during the performance of the BPI, the BPI will be aborted.
Factors Leading to Abort a BPI:
◗ Inverter to mains 2 source transfer.
◗ Load percent drops to <15%.
◗ Battery temperature outside 0-40°C (32-104°F).
◗ Percent load changes more than +/-5% from starting power level.
