5 +== Inputs and outputs ==
6 +
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:
14 +
15 +[[image:1734022225578-818.png||data-xwiki-image-style-alignment="center" data-xwiki-image-style-border="true" height="153" width="600"]]
16 +
17 +A list of available discrete input assignments is available in [[Input signals>>doc:Battery management systems.Additional information.2\. Strings controllers\: signals and errors.WebHome||anchor="HInputsignals"]].
18 +
19 +Inversion flags for discrete inputs are configured in the "Signals → Input discrete signals → Inversion" section:
20 +
21 +[[image:1734022225583-740.png||data-xwiki-image-style-alignment="center" data-xwiki-image-style-border="true" height="137" width="600"]]
22 +
23 +The behavior of “KEYRUN” signal can be configured in the "Signals → Input discrete signals → KEYRUN mode" section:
24 +
25 +[[image:1734022225584-474.png||data-xwiki-image-style-alignment="center" data-xwiki-image-style-border="true" height="87" width="600"]]
26 +
27 +The behavior of “CHARGE_ON” signal can be configured in the "Signals → Input discrete signals → CHARGE_ON mode" section:
28 +
29 +[[image:1734022225585-775.png||data-xwiki-image-style-alignment="center" data-xwiki-image-style-border="true" height="89" width="600"]]
30 +
31 +In both “KEYRUN mode” and “CHARGE_ON mode” sections:
32 +
33 +* Do nothing – power on device and do nothing;
34 +* Set “Join to discharge” – power on device and set “Join to discharge” signal immediately;
35 +* Set “Join to charge” – power on device and set “Join to charge” signal immediately;
36 +* Set “Discharge request” – power on device and set “Discharge request” signal immediately;
37 +* Set “Charge request” – power on device and set “Charge request” signal immediately.
38 +
39 +=== Current sensor ===
40 +
41 +The BMS Main 3X device has an ability to measure battery current by **3 external Hall-Effect current sensors**.
42 +
43 +Current sensor settings are configured in the "Signals → Current sensor" section:
44 +
45 +[[image:1734022225586-287.png||data-xwiki-image-style-alignment="center" data-xwiki-image-style-border="true" height="178" width="600"]]
46 +
47 +The device supports the following current sensor settings:
48 +
49 +* 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);
50 +* Connection – type of multiple sensors connection
51 +** One sensor (#1) – only first sensor is used to measure the battery current;
52 +** Two sensors (#1 and #2) in parallel – sensors are connected in parallel (the total battery current equals the sum of two sensors);
53 +** Two sensors (#1 and #2) in different branches – sensors located in two halves of the battery (used in batteries with a middle point);
54 +* Sensor 2, 3: Enable – a flag to enable the second of third current sensor;
55 +* Sensor 1, 2, 3: Nominal current – rated current I,,nom,, of the sensor according to the datasheet, A;
56 +* Sensor 1, 2, 3: Sensitivity – sensitivity of the current sensor according to the datasheet, V / I,,nom.,,;
57 +* Sensor 1, 2, 3: Invert – invert the sign of the measured value;
58 +* Sensor 1, 2, 3: Multiply charging current (experimental) – an experimental flag for scaling the charging current by given multiplier;
59 +* Sensor 1, 2, 3: Multiplier for charging current – charging current multiplier;
60 +* Sensor 1, 2, 3: REF_IN2 mode – mode of additional analog line:
61 +** Not connected;
62 +** Reference line – reference output of the sensor;
63 +** Low range (for the dual range sensor) - a second output of a dual-range sensor (for example, LEM DHAB series);
64 +* Sensor 1, 2, 3: Low range nominal current - rated current I,,nom,, of the low current line of dual range sensor according to the datasheet, A;
65 +* Sensor 1, 2, 3: Low range sensitivity – sensitivity of the low current line of dual range sensor according to the datasheet, V / I,,nominal.,,;
66 +* 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;
67 +* Calibrate – a flag to calibrate (find a 0A point) the current sensor when the device is started;
68 +* Calibration time – calibration time of the current sensor, millisecond;
69 +* Recalibrate current sensor – a command to calibrate the current sensor manually.
70 +

72 +
73 +Temperature sensors settings are configured in the "Signals → Temperature sensors" section:
