3.3.3 UPS Status page
The UPS status page shows the following information for each of the input / output / bypass lines.
Parameter Name Description
Frequency Line frequency (in Hertz)
Voltage Line RMS voltage (in Volts)
Line RMS current (in Amperes) Current
Power / True Power Line True Power (in Watt)
Load % The power capacity presently being used (percentage) [Output only]
Volt min Lowest input voltage in the present time-period (in Volts) [Input only]
Lowest input voltage in the present time-period (in Volts) [Input only] Volt max
Also the following information is presented:
Parameter Name Description
Input Line Bads Number of times the mains input went out-of-tolerance since UPS start-up
The present source of the output power Output Source
Note: none means there is no output power
Finally, a 3-ph system featuring the PMAD functionality will also show the following:
Parameter Name Description
The present output power factor. A positive value indicates an inductive load;
while a negative value indicateS a capacitive load.
Power factor
Note: the power factor cannot be reliably determined in low load conditions. In
this case, the value will not be available (N/A)
The output peak current Peak current
Share current In a parallel system ideally all the UPS are requested to contribute to the load
with the same amount of current, i.e. with no current share. The current share
occurs when an UPS exchanges some current with another UPS, so that this
current component doesn't feed the load.
The PMAD functionality detects the amount of share currents in a parallel
system. Obviously, single system do not provide this functionality and will show
this value as not available (N/A).
3.3.4 UPS Alarm page
This page presents the UPS active alarms (if any) with an indication of the time elapsed since the
activation (in seconds). Once again, the supported alarms depend on the specific UPS model.
For the meaning of each specific alarm refer to the relevant UPS documentation.
3.3.5 UPS PMAD page (3-ph version ONLY)
This page presents diagnostic related readings from UPSs implementing the PMAD (Preventive
Maintenance and Advanced Diagnostic) functionality. These include the following:
Parameter Name Description
The remaining time before a check of the specific devices / system is required Life Time
Count of failures and transients on mains input and bypass Mains Statistics
Bus Communication Qty of UPSs: Number of UPSs as currently seen in the parallel system.
(The reset button forces a refresh of the count and the display)
Channel table: The table shows the actual communication status over the two
redundant buses between the unit currently selected (in green bold) and other
units.
