Ups Alarm Page; Ups Pmad Page (3-Ph Version Only); Ups Test Page - GE Digital Energy 1018959 Operating Manual

Finally, a 3-ph system featuring the PMAD functionality will also show the following:
Parameter Name
Power factor
Peak current
Share current

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
Life Time
Mains Statistics
Bus Communication

3.3.6 UPS Test page

This page presents allows to initiate a specific UPS test, and reports the status of the last performed test
(if any). The page includes a table with clear explanation of the test result reading.
For an explanation of the various test procedures please refer to the applicable UPS documentation.

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)
The output peak 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).
Description
The remaining time before a check of the specific devices / system is required
Count of failures and transients on mains input and bypass
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.
