While the test is in progress:
•
The display will alternate between the Home screen and the BDT in Progress screen
shown at right.
•
The system alarms Battery Discharge, Voltage Low and SMR Voltage Low.
•
Low Load alarm will be suppressed.
•
SMR alarms will be shown in the SMR status.
Test time interval: The interval between tests can be set to 0-365 days.
When set to zero, the automatic execution of the test is disabled (set to Off). Display
messages below will be shown only if the test is enabled.
Time of test: Set the time of day the test is to be performed. This is a 24-hour clock.
Test duration: Set the duration of the test. Duration can be set from 5 minutes to 24 hours
in increments of 5 minutes.
Discharge rate: Set the rate of discharge. Rate can be set from 0 to 5000A. If rate is set to
zero, the control function is disabled and the battery will discharge under full load
current.
Note: The total load supplied by the system during the test must exceed the desired
battery discharge current by at least 10%. Rectifiers will supply the additional load,
leaving the battery string to supply a user defined current to the load.
End of test: Set the battery voltage that will terminate the test if reached before the test
duration set above.
At the end of test, whether ended by test duration or end voltage, normal operation is
restored and recharging of the battery string(s) is begun. The test result will be “Fail.”
Battery string end of voltage depends upon system voltage: 48V system 36V to 48V
Battery end of capacity: Set the remaining battery capacity at which the test must bend.
Capacity can be set from 25Ah to 9995Ah. If rate is set to zero, the control function is
disabled and the battery will discharge under full load current.
Reset of failed test alarm: This message appears when the preceding test fails and is not
reset. Press ENTER to reset the alarm and hide the message.
Abort MBT: This screen is available when a discharge test has been started.
BDT Results Screen
The final screen contains a brief test result message. The message appears on the second
line of the Last BDT display. Each message is explained below.
N/A – Not Available: No test has been performed.
Passed – Test ran for programmed duration without reaching an “End V” or “End Q” value.
Failed – Test terminated prematurely after reaching an “End V” or “End Q” value before the test duration expired. This will trigger a
“BDT Fail” alarm.
