BTC Notes:
1)
If the battery temperature sensor is not connected, compensation is based on the
ambient temperature sensor.
2)
If battery and ambient temperature sensors are connected, compensation is based
solely on the battery sensor.
3)
When temperature compensation is active, the SMR voltage setting is automatically
adjusted by the SCU as needed.
Battery cells per string: Set the number of physical cells in a string.
Battery charging current limit: Set the maximum battery charge current when the voltage
across the two battery strings is less than the deep discharge voltage (Vdd).
Battery deep discharge voltage (Vdd):
Battery charging current limit: Set the current when the battery voltage is between Vdd
and the float voltage (Vfl). This current is typically higher than that for the deeply
discharge battery.
System float voltage: Set the system output voltage at the output bus bar terminals.
System voltage drop: Set the maximum voltage drop as defined by: maximum rectifier
output – system float voltage. A typical value is 0.6V.
Equalization
Equalization on/off toggle:
If equalization in off, the following screens will not appear.
Battery charging current limit: Set the maximum equalization charging current (Vbattery
> Vfloat). This applies when batteries are being equalized.
Equalization voltage: Set the maximum voltage reached during equalization of the
batteries.
Equalization on/off toggle:
On – voltage trigger
Off – ampere/hour trigger
Equalization trigger, voltage: Set the voltage at which equalization will be initialized,
during battery discharge.
Equalization on/off trigger:
On – voltage trigger
Off – ampere/hour discharge trigger
Equalization A/h on/off toggle:
On – ampere/hour discharge trigger
Off – voltage trigger
