281 281  The device controls two processes: **joining battery modules** and **closing the main charging/discharging contactor**.
282 282  
283 -The operation of the **joining battery modules** depends on the signal received:
284 284  
285 -* If "Join to charge" is received, joining procedure is done as described in [[Charge>>doc:||anchor="HCharge"]] section;
286 -* If "Join to discharge" is received, joining procedure is done as described in [[Discharge>>doc:||anchor="HDischarge"]] section;
287 -* If both signals received, "Join to charge" has a priority.
284 +The operation of the **joining battery modules** is described by the following steps:
288 288  
289 -The operation of **closing main charging/discharging contactor **depends on the signal received:
286 +1. Battery modules are disabled. When the “Join to charge” or “Join to discharge” request is received and the voltage and corresponding current unbalance errors (Voltage unbalance (DCH), Voltage unbalance (DCH), Current unbalance (DCH), Discharging current unbalance) are cleared, go to step 2.
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 +1. Closing the precharging contactors of the battery modules (optional). Go to step 4.
289 +1. Closing the discharging contactors of the battery modules. The battery modules are self-balancing. Go to step 5.
290 +1. Checking intermodular balancing currents (the duration of the check is set in the settings). If there is no current unbalance (“Current unbalance (DCH)”) or errors are ignored (“Always on”), go to step 6, otherwise open all discharging contactors, and go to step 1.
291 +1. The battery modules are joined. If the “Join to discharge” request is cleared or "Discharging current unbalance" error occurs, go to step 1.

293 +The operation of **closing main discharging contactor** is described in the following steps:

294 294  1. The main discharging contactor “Discharging” is open. When the “Discharge request” is received, the voltage and current unbalance errors (“Voltage unbalance (DCH)”, “Current unbalance (DCH)”, “Discharging current unbalance”) are cleared, and the battery modules are joined, go to step 2.
