So that an incorrect Ah Discharged value does not affect cyclic battery charging in a hybrid
generator/battery power system, an incorrect Ah Discharged value will be corrected after one
discharge/recharge cycle:
•
Ah Discharged
is set to zero when the recharge reaches
Maximum Duration
(and
the battery is assumed to be fully charged).
•
Ah Discharged
is set to the
Start Ah Threshold
when the battery discharges down
to the
Voltage Threshold
.
•
Ah Discharged
is limited to a maximum value of Battery Capacity.
•
Ah Discharged
can be set to zero after a Fast Charge or Equalize cycle. See
•
Ah Discharged
can be automatically counted down when the system is in Float
state. See
on page 69.
•
Ah Discharged
can be manually reset to zero.
Temperature Compensation
As the ambient temperature of a battery drops (or rises) the voltage required to maintain full
charge increases (or decreases). Temperature Compensation automatically varies the float voltage
to cancel the effects of changing temperature.
Enable Temperature Compensation for optimum battery life and battery capacity over a wider
temperature range.
Temperature Compensation does
NOT
function during a Battery Test.
► To enable Temperature Compensation
•
Use the SC300 keypad to go to:
Control Processes > Temp. Compensation > Enable
.
•
Or, in DCTools/Web go to:
Control Processes >
Temperature Compensation
.

Voltage Offset
The adjustment to the bus voltage being applied
due to the Temperature Compensation. Offset is
zero when the battery temperature equals the
reference temperature.
Battery

The temperature measured by the battery
temperature sensor.
