53 +=== Main contactor ===

55 +The BMS Main 3X 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.

57 +The Main contactor algorithm supports the following modes:
58 +
59 +* Always on;
60 +* Automatic, when the main contactor closes by the internal charging and discharging algorithms at the same time with Precharging, Charging, Discharging and Charging/Discharging contactors.
61 +
62 +In “Always on” mode main contactor closes if all the following is true:
63 +
64 +* Other contactors are open;
65 +* There are no errors from the "Errors 1, 2 ..." bitfileds.
66 +
67 +In “Always on” mode main contactor opens if all the following is true:
68 +
69 +* Other contactors are open;
70 +* There is an error from the the "Errors 1, 2 ..." bitfileds.
71 +
72 +In “Automatic” mode, the main contactor closes by internal algorithms at the same time with other contactors.
