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:

330 +* Charging contactor is open;

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.

491 -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.
492 -
493 -The Main contactor algorithm supports the following modes:
494 -
495 -* Always on;
496 -* Automatic;
497 -* On demand.
498 -
499 -In “Always on” mode main contactor closes if all the following is true:
500 -
501 -* Charging contactor is open;
502 -* Discharging contactor is open;
503 -* There are no errors from the list below:
504 -** Overcurrent;
505 -** Undervoltage;
506 -** Overvoltage;
507 -** High temperature (CH);
508 -** High temperature (DCH);
509 -** Unallowable charging;
510 -** Critical error.

512 -In “Always on” mode main contactor opens if all the following is true:
513 -
514 -* Charging contactor is open;
515 -* Discharging contactor is open;
516 -* There is an error from the list below:

519 -** Overvoltage;
520 -** High temperature (CH);
521 -** High temperature (DCH);
522 -** Unallowable charging;
523 -** Critical error.
524 -
525 -In “Automatic” mode, the main contactor closes by internal charging and discharging algorithms at the same time with Precharging, Charging and Discharging contactors.
526 -
527 -In “On demand” mode, the main contactor closes by external the “Close Main contactor” request.
