•
ConstCurrT Curr:
Constant current setting for a
Constant Current Battery Discharge Test.
•
Short Test:
Enables or disables a Short Battery Discharge
Test. A Short Battery Discharge Test is a short duration
battery discharge test used to verify that parallel
batteries are discharging equally. If the discharge current
difference between the two batteries exceeds a preset
value, an alarm is generated.
Note:
This test requires a system with two battery shunts.
•
ShortTest Cycle:
Short Battery Discharge Test
interval.
•
Short Test Time:
Short Battery Discharge Test
duration.
•
Max Diff Curr:
An alarm is generated if the maximum
difference between discharge currents of the two
batteries exceeds this limit.
•
BattTestLowCap:
If remaining battery capacity is less
than this value, a battery discharge test will not be
started.
TEMP COMP MENU
Menu Navigation:
Main Menu / Settings / Battery / Temp Comp
Note: For WEB Interface; menu items are found under Device
Information / Battery Group / Settings Tab.
"Temp Comp" Parameter Settings:
•
Temp CompCenter:
Sets the temperature at which the
system operates at normal voltage levels.
•
Temp Comp Coeff:
Sets the temperature compensation
slope or rate of change per °C above or below the "Temp
Comp" setting. This value is expressed in millivolt per °C
per string (mV/°C/str). For example, for a rate of change
of
72 mV/
°
C/str
in a 24-cell 48V nominal battery string,
the rate of change is 3 mV per cell.
•
TempComp Sensor:
Select "None" for no temperature
compensation, or the temperature probe (SMTemp8 T8 /
... / SMTemp8 T1 / ... / SMTemp1 T8 / ... / SMTemp1 T1 /
EIB T2 / EIB T1 / IB2 T2 / IB2 T1) sensing battery
temperature for temperature compensation. You can
also select Maximum or Average which takes the
maximum or average reading of the temperature probes
(any of SMTemp8 T8 / ... / SMTemp8 T1 / ... / SMTemp1
T8 / ... / SMTemp1 T1 / EIB T2 / EIB T1 / IB2 T2 / IB2 T1) set
as battery temperature probes. When used with an SM-
BRC, you can select to average the SM-BRC temperature
probe readings.
Note:
The temperature compensation sensor is also the
sensor which displays the battery temperature on
the Web Interface’s Homepage.
•
Comp Temp High2:
Allows you to set a high
compensation temperature alarm 2 point.
•
Comp Temp High1:
Allows you to set a high
compensation temperature alarm 1 point.
•
Comp Temp Low:
Allows you to set a low compensation
temperature alarm point.
•
Temp Comp Clamp:
Enables or disables the temperature
compensation voltage clamp feature.
•
Temp Comp Max V:
Upper voltage limit where battery
temperature compensation clamps the voltage.
•
Temp Comp Min V:
Lower voltage limit where battery
temperature compensation clamps the voltage.
CAPACITY MENU

Time 0.5C10:
Discharge time with a discharge current of
0.5C10.
•
Time 0.6C10:
Discharge time with a discharge current of
0.6C10.
•
Time 0.7C10:
Discharge time with a discharge current of
0.7C10.

0.9C10.
•
Time 1.0C10:
Discharge time with a discharge current of
1.0C10.
