Number of times the mains input went out-of-tolerance since UPS start-up
The present source of the output power
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.

Note: the power factor cannot be reliably determined in low load conditions. In
this case, the value will not be available (N/A)

Share 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:
