6.9.1 Results of last Battery Discharge Test - (Last BDT)
The remaining screen of the Battery Discharge Test gives details of the results of the last
discharge test. The explanation of the codes are as follows:
Not Available. No test has been performed yet.
The test lasted for desired duration without reaching “End
V” or “End Q” levels
Test terminated prematurely reaching “End V” or “End Q”
level before duration time expired. This will trigger “BDT
Fail” MCSU-4 level alarm.
The test was terminated due to a failure of the AC supply
detected either by the AC monitor or all SMRs being off.
A cell in a battery string discharged below safe level -
alarmed, available only when BCM fitted and activated. BDT
is flagged as having failed.
Aborted due to loss of control of rectifiers, not alarmed.
Aborted due to load being too low to control discharge
current, not alarmed.
Aborted due to load being too high to support controlled
discharge. Flagged if all SMRs indicate current limit.
Possible only if rectifiers failed during the test. Not alarmed.
Terminated manually using MCSU-4 Front Panel or from
WinCSU-2
