Battery impedance
The Battery impedance page in the Diagnose section can be used to check the condition of the
connected 12 Vdc (back-up) battery. See also Multifunction power supply, page 53 .
The following information is presented on the Battery impedance page:

Notice that the system continuously do measurements on the background and report the
results. On the diagnostics (Battery impedance) page, the measurements can be started
manually.

Description
A Start button is presented to start the battery impedance calculation
of the connected battery.
Shows the name of the Mps to where the battery is connected. See
Multifunction power supply, page 53 .
Shows the configured capacity (in Ah) of the connected battery. See
Multifunction power supply, page 53 .
Result of the measurement and depends on the connected battery
capacity.
Result of the measurement and depends on the connected battery
capacity.
IMPORTANT: The diagnostics page battery impedance is only available
when battery supervision is enabled. See Multifunction power supply,
page 53 .
One of the following measurement results will be shown (No error
messages will be shown):
–
Busy: the measurement is currently in progress.
–
Unknown: possible no battery connected and/or no measurement
was/is started.
–
Preliminary: measurement results known but measured while the
battery was not fully loaded.
–
Stable: measurement results known while the battery was fully
loaded.
Battery related fault messages will be shown here. See Multifunction
power supply (MPS), page 147 and/or Troubleshooting, page 133
Check the battery connections and settings as defined in Multifunction power supply,
page 53 .

When OK:
Click the Start button:
–
As soon the Start button is clicked, the system will measure the connected battery
capacity and will generate the results for each item as described in the previous
table.
