Type
The configuration of this field selects the batter type, Flooded or
Valve Regulated (sealed). This parameter is used in reserve time
prediction and enhanced battery test features. Move the cursor to
the field and use the <+> or < - > key to adjust the threshold value.
Press <ENTER> to save the change.
7. Thermal Comp
This feature allows dynamic control of sealed cell battery voltage as a
function of temperature.
Enabled
Enables or Disables the Thermal Compensation Feature. Move the
cursor to the field and use the <+> or < - > key to Enable or Disable.
Press <ENTER> to save the change.
High Temp Comp
This feature allows the system to compensate for high temperatures.
Volt Step Down
Battery step temperature can be set from 113 - 185F. At this
temperature, the system voltage is reduced by 0.17 X # of cells/
string.
High Comp Limit
This sets the maximum temperature for which thermal compensation
is active.
Decrease
This sets the slope (mV/degC) for high temperature compensation.
Nominal Temp
This field set the temperature at which no compensation is
required. The system voltage is at the setpoint float mode.
Low Temp Comp This feature allows the system to compensate for low temperatures.
Low T Comp This enables or disables the low temperature compensation feature.
Low Comp Limit
This sets the minimum temperature for which thermal compensation is
active.
Increase This sets the slope (mV/degC) for low temperature compensation.
