	55	+The Main contactor algorithm supports the following modes:
56	56
57		-* Other contactors are open;
58		-* There are no errors from the "Errors 1, 2 ..." bitfileds.
	57	+* Always on;
	58	+* 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.
