•

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

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

Menu Navigation:

Main Menu / Settings / Battery / Capacity

Note: For WEB Interface; menu items are found under Device

Information / Battery Group / Settings Tab.

"Capacity" Parameter Settings:

•

Charging Eff:

Value used to calculate remaining capacity

of the battery.
