353 353  == 3.6.12 Unallowable charging protection ==
354 354  
355 +The BMS can detect that the battery is charging through the discharging circuit and protectively open the discharging relay to prevent unallowable battery operation.
356 +
357 +To change the parameters of the unallowable charging protection, select the menu "Protections → Unallowable charging protection":
358 +

360 +In this section:
361 +
362 +* Enable – a flag to enable the protection;
363 +* Delay before setting the error, second;
364 +* Delay before clearing the error, second;
365 +* Lock the error until the device is reset.
366 +
367 +If there is charging the battery through the discharging circuit detected, the "Unallowable charging" error is generated.
368 +
369 +Error generation conditions:
370 +
371 +* the charging relay is open and the battery current is not zero during the “Delay before setting the error” time.
372 +
373 +Conditions for removing the error:
374 +
375 +* the battery current is zero during the “Delay before clearing the error” time.

355 355  == 3.6.13 Stuck contactor protection ==
356 356  
384 +The BMS Main 2.x protects contactors against sticking.

386 +To change the protection parameters against sticking, select the menu "Protections → Stuck contactor protection":

396 +If there is a stuck contactor, the “Stuck contactor” error is generated.
397 +
398 +Error generation conditions:
399 +
400 +* charging and discharging contactors are open, but the “Charging current present” or “Discharging current present” signal is set.

357 357  == 3.6.14 Contactor feedback check ==
358 358  
404 +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 section Input and output signals).
