431 -The BMS Main 2.x can receive feedback signals from contactors and detect discrepancy between the control value and the feedback signal. To enable specific contactor protection, one of the discrete input must be set as corresponding contactor feedback signal (see [[Input and output signals>>doc:Battery management systems.EOL devices.BMS Main 2\.1.3\. Configuration.3\.3 Input and output signals.WebHome]]).
