Safiery CANbus Alternator Controller

shunt is present and working, as will the arrival of battery current measurements via the CAN. Once this determination is made no additional checks will be made – as a valid operation condition for the regulator may at times have a battery current of 0A (example, when actively regulating current to 0A in FLOAT mode).

Ignore Sensors: <WHOLE NUMBER ( 0  255 ) > A companion to Required Sensors , this bit-flag parameter will cause the regulator to ignore measurements on the flagged sensors. Typically this is only used where sensing is done via Remote Sensing, example: If Battery Current is supplied via CAN from the BMS, and the local current shunt is not used - by setting the Ignore Sensor bit, random noise is prevented from causing miss readings. The stator is another key example, if not used one can ground that signal wire, or set the Ignore Sensor bit for the Stator. Ignore Sensors is a number created by summing up the value associated with each potential critical sensor. For example: if you wished to ignore the Alternator temperature and current shunt readings, you would enter 5 (1+4).

Be careful with the relationship between Ignore and Required Sensors, an ignored senor will cause a positive trap if it is ‘required’ and the value is not supplied elsewhere. Also be careful with the Feature-In signal wire, especially as it is at times used with BMS’s in a legacy configuration to signal that charging should be stopped.

BMS Amp Cap: <WHOLE NUMBER ( 0  2500 ) > BMS Amperage Capacity (<BMS Amp Cap> ) issued to define a global system limit in a like way that <System Watts Capacity> . BMS Amp Cap defined the maximum charge amperage the BMS is defined to support. If the battery $CPB MaxAmps (aka, C rate) allows current to exceed the maximum allowed BMS current, the regulator will restrict current so as to not over-load the BMS rating. BMS Amp Capacity is clipped to 10A increments, so a defined value of 258A will be saved as 250A

If BMS Aggregation is enabled, the total BMS current allowed will be increased to match that of the total recognized online and active BMS’s.

If a RBM is controlling the charge cycle, sending in goal battery current limits, BMS Amp Cap will be ignored.

Set = 0 (Default) to disable BMS Current Limit.
