Discharge test failure
At the MAP terminal
1 To access the PES MAP display level, type
>MAPCI;MTC;PM;PES
and press the Enter key.
2 To post the appropriate alarm state, type
>POST alarm_state
and press the Enter key.
where
alarm_state
is RED or AMBER
3 To disable the automatic battery rotation and testing, type
>AUDIT DISABLE
and press the Enter key.
4 From log PES117, determine the battery string voltage that tests below
OPM_VOLT_TST_DIS. If the log marks strings 1 and 5 as failed, determine
if string 1, 5, or both cause the alarm.
Note: For OPMs with MTU: Default OPM_VOLT_TST_DIS = -495 or
-49.5 Vdc for Eagle Picher and Yuasa batteries. For OPMs with LTU:
Default OPM_VOLT_TST_CHG is offset by OPM_VOLT_TST_LTU
ADJUSTMENT (default=10) and then truncated. -495+10 = -485 Trunc
(-485)= -480 or -48 Vdc for Eagle Picher and Yuasa batteries.
5 To open the circuit to the failed battery string pair, type
>OPENCKT n
and press the Enter key.
where
n
is the number of the string pair (0-3)
6 Perform the OPM site tests.
7 The inspection procedure is complete.
