EL 3000 B Series
3.9.9.3 Other parameters
These parameters are available in both battery test modes, but the values are separately adjustable in each.
Parameter Range Description
Discharge voltage 0...Nominal value of U Variable voltage threshold to make the test stop when reached (is
connected to the battery voltage on the DC input of the load)
Discharge time 0...10 h Maximum test time after which the test can stop automatically
Discharge capacity 0...99999 Ah Maximum capacity to consume from the battery after which the test
can stop automatically
Action NONE, SIGNAL, End
of test

run once the adjusted values for those parameters are reached:
NONE = No action, test will continue
SIGNAL = Text “Time limit” will be displayed, test will continue
End of test = The test will stop
3.9.9.4 Displayed values
During the test run, the display will show a set of values and
status:
• Actual battery voltage on the DC input in V
• Actual discharge current in A
• Actual power in W
• Consumed battery capacity in Ah
• Consumed energy in Wh
• Elapsed time in HH:MM:SS,MS
• Regulation mode (CC, CP, CR)
3.9.9.5 Possible reasons for battery test stop
The battery test function run can be stopped by different reasons:
• Manual stop on the HMI with buttons or
• After the max. test time has been reached and if action “End of test” was set for it
• After the max. battery capacity to consume has been reached and if action “End of test” was set for it
• Any device alarm which would also switch off the DC input, like OT
• Passing the discharge voltage threshold, which is equivalent to any voltage drop on the DC input caused by
whatever reason
After an automatic stop, caused by any of the listed reasons and removing the cause of an
alarm, the test can be continued. Reset of counted values is done by leaving the function gen-
erator screen.
