Factstar - FS3. The Factstar shall be used to monitor and record battery float, charge/discharge and ripple currents, total string and optionally up to 4 segment voltages and ambient or pilot jar temperature. The Factstar shall continuously calculate battery used capacity (charge level) and generate alarms on high temperature, high float current, open string, high ripple current conditions, optionally alarm can be trigged based on segment voltage abnormalities (outside predefined limits). One/ optionally two alarm contacts shall be operator configurable(programmable). Configuration data shall be stored in the device non-volatile memory.
