•
BTRM Voltage:
Voltage that the system is set to
when battery temperature exceeds the “BTRM
Temp High2” setting.
•
ABCL Point:
The ABCL (Active Battery Charge Current
Limit) point is the maximum Li-Ion battery charging
current setting.
CHARGE MENU
Menu Navigation:
Main Menu / Settings / Battery / Charge
Note: For WEB Interface; menu items are found under Device
Information / Battery Group / Settings Tab.
"Charge" Parameter Settings:
•
Float Voltage:
Float Charge output voltage setting.
•
EQ Voltage:
Equalize Charge output voltage setting.
•
Batt Curr Limit:
Maximum battery charging current
setting. For example, a value of 0.150C10 means that the
charging current is limited to 15% of the battery’s
nominal capacity.
•
Over Curr Lmt:
Battery over current alarm setting. For
example, a value of 0.300C10 means that when the
charging current reaches 30% of the battery’s nominal
capacity, an alarm will be extended.
•
Auto EQ:
Enables or disables the Automatic Equalize
Charge feature. When enabled, the following parameters
can be set.
•
EQ Start Curr:
The system is transferred to Equalize
Charge mode when battery charge current increases
to this setting. For example, a value of 0.060C10
means that an Automatic Equalize is started if the
battery charge current is greater than 6% of the
battery’s nominal capacity.
•
EQ Start Cap:
The system is transferred to Equalize
Charge mode when remaining battery capacity
decreases to this setting.
•
EQ Stop Curr:
When in Equalize Charge mode and the
battery charge current decreases below this setting for
the "EQ Stop Delay" time period, the system is transferred
to Float Charge mode. For example, a value of 0.010C10
means that when the charging current is less than 1% of
the battery’s nominal capacity, the system returns to the
Float mode.
•
EQ Stop Delay:
See "EQ Stop Curr" above.
Note:
If the power system has been automatically placed in
Equalize mode, disabling Auto EQ will
not
return the
system to Float mode until the current Equalize cycle is
completed. To return immediately to Float mode,
navigate as follows: Main Menu / Manual / Batt Group /
“EQ/FLT Control”, and select Float Charge.
•
Maximum EQ Time:
This is the maximum duration, in
minutes, that an Automatic Equalize Charge will last
regardless of the other settings.
•
Cyc EQ:
Enables or disables cyclic (scheduled) Equalize
charging. When enabled, the following parameters can
be set.
•
Cyc EQ Interval:
Cyclic (scheduled) Equalize charging
interval.
•
Cyc EQ Duration:
Cyclic (scheduled) Equalize
charging duration.
TEST MENU
Menu Navigation:
Main Menu / Settings / Battery / Test
Note: For WEB Interface; menu items are found under Device
Information / Battery Group / Settings Tab.
"Test" Parameter Settings:
•
Test Volt Lmt:
System output voltage setting during a
battery discharge test.
•
Test End Volt:
This is the “end of test voltage level” for
battery discharge tests. A battery discharge test will end
if battery voltage decreases to this setting.
•
End Test Time:
This is the "end of test time period” for
battery discharge tests. A battery discharge test will end
if this time period is exceeded.
•
EndTestCapacity:
This is the "end of test remaining
battery capacity” for battery discharge tests. A battery
discharge test will end if remaining battery capacity
decreases to this setting. For example, a value of
0.700C10 means that when the discharging current
reaches 70% of the battery’s nominal capacity, the
battery test is ended.
•
RecordThreshold:
This setting indicates the interval
battery voltage is recorded during a battery discharge
test.
•
AC Fail Test:
Enables or disables starting a battery
discharge test during an AC input failure condition.
•
Planned Tests:
Number of planned battery discharge test
per year. A "0" setting disables the planned test feature.
•
Test 1 (M-D Hr):
Setting for when planned battery
discharge test #1 occurs. Note that there can be up
to (12) battery discharge tests per year.
•
Const Curr Test:
Enables or disables a Constant Current
Battery Discharge Test. During this test, the Controller
automatically adjusts the rectifiers output voltage to
maintain the battery discharge current at a preset value
"ConstCurrT Curr".
