269 269  Charge/Discharge contactor has two algorithms of operation:
270 270  
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;
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;
272 272  * Independent - Charge/Discharge contactor is based on its own controller.
273 273  
274 +In "Dependent" mode the Charge/discharge contactor 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).

275 -The device supports the following charging/discharging modes:
276 +The device supports the following discharging modes:
276 276  
277 -1. Charging/Discharging is always allowed (Always on) – the device ignores voltage and current unbalance of the battery modules and commands to close the discharging contactors of the battery modules and the main discharging contactor.
278 -1. Charging/Discharging is allowed if all battery modules are balanced (Balanced).
279 -1. Charging/Discharging is allowed for most balanced battery modules (Partially balanced). Unbalanced modules are disconnected from the common bus and do not participate in the discharging.
278 +1. Discharging is always allowed (Always on) – the device ignores voltage and current unbalance of the battery modules and commands to close the discharging contactors of the battery modules and the main discharging contactor.
279 +1. Discharging is allowed if all battery modules are balanced (Balanced).
280 +1. Discharging is allowed for most balanced battery modules (Partially balanced). Unbalanced modules are disconnected from the common bus and do not participate in the discharging.

281 -The device controls two processes: **joining battery modules** and **closing the main charging/discharging contactor**.
282 +The device controls two processes: **joining battery modules** and **closing the main discharging contactor** “Discharging”.

283 283  
284 284  The operation of the **joining battery modules** is described by the following steps:
285 285  
286 -1. Battery modules are disabled. When the “Join to discharge” “Join to discharge” request is received and the voltage and current unbalance errors (Voltage unbalance (DCH), Current unbalance (DCH), Discharging current unbalance) are cleared, go to step 2.
287 +1. Battery modules are disabled. When the “Join to discharge” request is received and the voltage and current unbalance errors (Voltage unbalance (DCH), Current unbalance (DCH), Discharging current unbalance) are cleared, go to step 2.
287 287  1. Checking the voltage unbalance of battery modules (the duration of the check is set in the settings). If there is no imbalance or errors are ignored (“Always on” and “Partially balanced”), go to step 3, otherwise open all discharging contactors, and go to step 1.
288 288  1. Closing the precharging contactors of the battery modules (optional). Go to step 4.
289 289  1. Closing the discharging contactors of the battery modules. The battery modules are self-balancing. Go to step 5.
