High T Start
The controller begins reducing the float
voltage when the highest measured battery
temperature reaches this value
35°C
25 – 60 °C
(77 – 140°F)
High Slope
If battery temperature exceeds the High T
Start value, the controller linearly reduces the
plant voltage by this slope
72 mV/°C 0 – 250 mV/°C
High V Stop
The minimum voltage to which the controller
reduces plant voltage for thermal
compensation
50.5 V
48 – 57 V
(max HVSD –
1V)
Low T Start
The controller begins increasing the float
voltage when the lowest measured battery
temperature reaches this value
-20°C
-20 – 25 °C
(-4 – 77°F)
Low Slope
If battery temperature is below the Low T
Start, the controller linearly increases the
plant voltage by this slope
0 mV/°C 0 – 250 mV/°C
Low V Stop
The maximum voltage to which the controller
raises plant voltage for thermal
compensation
56 V
48 – 57 V
(max HVSD –
1V)
Runaway
Temp
The temperature at which the controller
reduces the Float Voltage to Thermal
Runaway Clamp Voltage (Runaway V)
60°C
45 – 70 °C
(113 – 158°F)
Runaway V
The voltage to which the controller reduces
while temperature is above the Runaway
Temperature value
50 V 45 – 50 V
