$SCA: - Changes ALTERNATOR (and System) parameters Used to update the system configuration entries associated with the Alternator and System.
$SCA: <BTS2ATS?>, < Alt Target Temp >, <Alt Derate (norm) >,<Alt Derate (small) >,<Alt Derate (half) >, <PBF>, <Alt Amp Cap>, <System Watt Cap.>, <Amp Shunt Ratio>, <Shunt Reversed?>, <Idle RPMs>, <Warmup Delay>, <Required Sensors>, <Ignore Sensors>, <BMS Amp Cap>
BTS2ATS?: <WHOLE NUMBER (0, or 1) > If BTS2ATS? is set = 1, the Battery Temperature Sensor will be treated as a 2 nd Alternator Temperature Sender. The warmer of the two sensors will be used as Alternator Temperature for both reporting and regulation. Useful if two alternators are being driven from one regulator using a common field. Make sure the Battery temperature is being supplied via the CAN. Using the BTS for a 2 nd ATS is also useful with the DC-DC converter option; it allows two alternators to be monitored.
(Default = 0)
Alt Target Temp: <WHOLE NUMBER (15 150)> Operating temperature the regulator should attempt to keep the Alternator under in degrees C. If the Alternator temperature exceeds this value, the regulator will reduce field current to allow the alternator to return to a safe operating temperature. If the Alternator temperature continues to rise and exceeds this temperature by 10% the regulator will fault out and stop producing power.
Alt Target is used by the DC-DC converter to reduce power transfer as alternators reach their target temperature.
Alt Derate(norm), Alt Derate(small),
Alt Derate(half): <FLOATING POINT NUMBER (0.0 1.00) > These derating values are used to limit the alternator ’ s maximum current output to some % (10% to 100%) of its demonstrated capability (see Alt Amp Cap ). The three values correspond to the mode the Alternator:
Normal - Condition when either of the other modes are not selected.
Small Alternator Mode – selected via DIP switch 8.
