171 +== 3.5.5 Main contactor ==
172 +
173 +The BMS Main 2.x has a relay to control the main contactor. The main contactor is usually placed in the common (minus) battery line for opening the charge and discharge circuits in a case of sealing of the charging or discharging contactor.
174 +
175 +The main contactor closes if there are no errors from the list below:
176 +
177 +* Overcurrent;
178 +* Undervoltage;
179 +* Overvoltage;
180 +* High temperature (charging);
181 +* High temperature (discharging);
182 +* Unallowable charging;
183 +* Critical error.
184 +
185 +The main contactor opens if the charging and discharging relays are opened and any of the following conditions is met:
186 +
187 +* charging or discharging current is detected during a set time;
188 +* voltage of any cell is lower than the minimum cell voltage configured in the section "Protections → Undervoltage protection" during a set time;
189 +* voltage of any cell is greater than the maximum cell voltage configured in the section "Protections → Overvoltage protection" during a set time;
190 +* temperature of any cell is greater than the maximum cell temperature configured in the section "Protections → High temperature protection" during a set time;
191 +* Critical error stays on during a set time.
192 +
193 +To change the parameters of the main contactor, select the menu "Cells → Main contactor":

197 +In this section:
198 +
199 +* Enable – a flag to enable the main contactor control;
200 +* Delay before opening the contactor – a time which is used to detect conditions for opening the contactor, second;
201 +* Keep the contactor open until the device is reset – a flag for keeping the main contactor opened until the system be reset.
202 +
203 +== 3.5.6 Power down control ==
204 +
205 +The BMS Main 2.x can command the BMS Power Control board to shut down the battery system if the battery voltage is low or the battery is idle for a long time. The BMS Main 2.x interacts with the BMS Power Control using the “Power down request” and the “Acknowledgement of power down” discrete signals.
206 +
207 +Shutting down the battery system is performed according to the following conditions:
208 +
209 +* the battery voltage is below the minimum level;
210 +* the “Charger connected” signal is cleared for 60 seconds.
211 +
212 +The BMS Main 2.x also shuts down the battery if it stays in the “Charging OFF”, “Discharging OFF”, “Relaxed (after charging)” or “Relaxed (after discharging)” for the set time.
213 +
214 +To change the parameters of the power down control, select the menu "Cells → Power down control":

218 +In this section:
219 +
220 +* Enable – a flag to enable the power down control;
221 +* Minimum voltage – a minimum voltage level of the battery below which the BMS commands to shut down the battery, V;
222 +* Idle time – a time of battery inactivity after which the battery is shut down, second;
223 +* Wait the "Power up/down request" signal is cleared (on startup) – a flag to enable delay for clearing the “Power up/down request” signal while starting the BMS.
