207 -If the "Heater" assignment is selected, a low battery temperature signal is outputted to the relay (see [[Low temperature protection>>doc:Battery management systems.BMS Main 2\.1 (End-of-Life).3\. Configuration.3\.6 Battery protection.WebHome||anchor="HLowtemperatureprotection"]]) or a signal "Heater" (see [[Heater control>>doc:Battery management systems.BMS Main 2\.1 (End-of-Life).3\. Configuration.3\.6 Battery protection.WebHome||anchor="HHeatercontrol"]]).
235 +If the "Balancing series 2" assignment is selected, the relay is used to connect a balancing resistor to the cell series 2 (see section Series balancing).
208 208  
209 -If the "Precharging" assignment is selected, the relay is used to charge the capacitive load (see [[Discharging control>>doc:Battery management systems.BMS Main 2\.1.3\. Configuration.3\.5 Battery control.WebHome||anchor="HDischargingcontrol"]]).
237 +If the "Discharging (AUX)" assignment is selected, the relay is used to power external equipment (see section Powering external equipment).
210 210  
211 -If the "Balancing series 1" assignment is selected, the relay is used to connect a balancing resistor to the cell series 1 (see [[Series balancing>>doc:Battery management systems.BMS Main 2\.1.3\. Configuration.3\.4 Battery parameters.WebHome||anchor="HSeriesbalancing"]]).

217 217  If the "Main contactor" assignment is selected, the relay is used to close the main contactor in the common (minus) power bus.
218 218  
219 219  If the "Power up" assignment is selected, the relay is used to close the contactor in the BMS Main power bus.
