307 +The BMS Main 3 device controls the main contactor. The main contactor is usually placed in the common (minus) battery line for opening the charge and discharge circuits in case of sealing of the charging or discharging contactors.
308 +
309 +The Main contactor algorithm supports the following modes:
310 +
311 +* Always on;
312 +* Automatic;
313 +* On demand.
314 +
315 +In “Always on” mode main contactor closes if all the following is true:

328 +In “Always on” mode main contactor opens if all the following is true:
329 +
330 +* Charging contactor is open;
331 +* Discharging contactor is open;
332 +* There is an error from the list below:

335 +** Overvoltage;
336 +** High temperature (CH);
337 +** High temperature (DCH);
338 +** Unallowable charging;
339 +** Critical error.
340 +
341 +In “Automatic” mode, the main contactor closes by internal charging and discharging algorithms at the same time with Precharging, Charging and Discharging contactors.
342 +
343 +In “On demand” mode, the main contactor closes by external the “Close Main contactor” request.

393 +=== Precharge ===
394 +

486 -=== Main contactor ===
487 -
488 -The BMS Main 3 device controls the main contactor. The main contactor is usually placed in the common (minus) battery line for opening the charge and discharge circuits in case of sealing of the charging or discharging contactors.
489 -
490 -The Main contactor algorithm supports the following modes:
491 -
492 -* Always on;
493 -* Automatic;
494 -* On demand.
495 -
496 -In “Always on” mode main contactor closes if all the following is true:
497 -
498 -* Charging contactor is open;
499 -* Discharging contactor is open;
500 -* There are no errors from the list below:
501 -** Overcurrent;
502 -** Undervoltage;
503 -** Overvoltage;
504 -** High temperature (CH);
505 -** High temperature (DCH);
506 -** Unallowable charging;
507 -** Critical error.
508 -
509 -In “Always on” mode main contactor opens if all the following is true:
510 -
511 -* Charging contactor is open;
512 -* Discharging contactor is open;
513 -* There is an error from the list below:
514 -** Overcurrent;
515 -** Undervoltage;
516 -** Overvoltage;
517 -** High temperature (CH);
518 -** High temperature (DCH);
519 -** Unallowable charging;
520 -** Critical error.
521 -
522 -In “Automatic” mode, the main contactor closes by internal charging and discharging algorithms at the same time with Precharging, Charging and Discharging contactors.
523 -
524 -In “On demand” mode, the main contactor closes by external the “Close Main contactor” request.

533 -* Algorithm – main contactor control algorithm:
534 -** Always on – contactor is always closed;
535 -** Automatic – contactor closes by internal charge and discharge algorithms;
536 -** On demand – contactor is closed by an external request;
537 -* Time to keep the contactor closed before closing the others – a time for other contactors to be open after the main contactor is closed;
538 -* Delay before opening the contactor – a time which is used to detect conditions for opening the contactor, s;
539 -* Keep the contactor open until the device is restarted – a flag for keeping the main contactor open until the system is reset.
