7 -=== Discrete inputs ===
8 -
9 -The BMS Main 3X device has **6 discrete inputs** that detect signal line closing to the virtual ground, and **2 inputs** that detect 9-32V input voltage. For each discrete input, its assignment and inversion flag are set.
10 -
11 -Also, BMS has two additional configurable inputs named “KEYRUN” and “CHARGE_ON”, each serves 9-32V input voltage. Those inputs serve as power buttons with additional functions that can be set.
12 -
13 -Assignments of discrete inputs are configured in the "Signals → Input discrete signals → Assignments" section:

36 -* Do nothing – power on device and do nothing;
37 -* Set “Join to discharge” – power on device and set “Join to discharge” signal immediately;
38 -* Set “Join to charge” – power on device and set “Join to charge” signal immediately;
39 -* Set “Discharge request” – power on device and set “Discharge request” signal immediately;
40 -* Set “Charge request” – power on device and set “Charge request” signal immediately.
41 -
42 -=== Current sensor ===
43 -
44 -The BMS Main 3X device has an ability to measure battery current by **3 external Hall-Effect current sensors**.

49 -
50 -The device supports the following current sensor settings:
51 -
52 -* Calculate the battery current as the sum of battery modules currents – a flag that determines overall current as sum of battery modules currents (if flag is not set, device uses measurements from a physical current sensor);
53 -* Connection – type of multiple sensors connection
54 -** One sensor (#1) – only first sensor is used to measure the battery current;
55 -** Two sensors (#1 and #2) in parallel – sensors are connected in parallel (the total battery current equals the sum of two sensors);
56 -** Two sensors (#1 and #2) in different branches – sensors located in two halves of the battery (used in batteries with a middle point);
57 -* Sensor 2, 3: Enable – a flag to enable the second of third current sensor;
58 -* Sensor 1, 2, 3: Nominal current – rated current I,,nom,, of the sensor according to the datasheet, A;
59 -* Sensor 1, 2, 3: Sensitivity – sensitivity of the current sensor according to the datasheet, V / I,,nom.,,;
60 -* Sensor 1, 2, 3: Invert – invert the sign of the measured value;
61 -* Sensor 1, 2, 3: Multiply charging current (experimental) – an experimental flag for scaling the charging current by given multiplier;
62 -* Sensor 1, 2, 3: Multiplier for charging current – charging current multiplier;
63 -* Sensor 1, 2, 3: REF_IN2 mode – mode of additional analog line:
64 -** Not connected;
65 -** Reference line – reference output of the sensor;
66 -** Low range (for the dual range sensor) - a second output of a dual-range sensor (for example, LEM DHAB series);

69 -* Sensor 1, 2, 3: Threshold for low range – a threshold current value at which the device uses the readings of the high current sensor instead of low current, A;
70 -* Calibrate – a flag to calibrate (find a 0A point) the current sensor when the device is started;
71 -* Calibration time – calibration time of the current sensor, millisecond;
72 -* Recalibrate current sensor – a command to calibrate the current sensor manually.
