269 +Charge/Discharge contactor has two algorithms of operation:
270 +
271 +* Dependent - Charge/Discharge contactor depends on Charge and Discharge algorithms and their signals and behaves as Charging contactor if Charging signal is set, otherwise – as Discharging contactor;
272 +* Independent - Charge/Discharge contactor is based on its own controller.

269 269  The charge/discharge contactor (“Charging/Discharging” signal) receives a “Charging” signal (generated by the charge controller) if a “Charge request” signal is received from the upper-level system. In all other cases, the "Discharging" signal is output to the contactor (generated by the discharge controller).
