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 +The device supports the following assignments for discrete inputs:
18 +
19 +* No input – input is not used;
20 +* Battery cover – a signal from the battery cover;
21 +* Charge request – a request to close the charging contactor;
22 +* Precharge request – a request to close the precharging contactor;
23 +* Discharge request – a request to close the discharging contactor;

29 +* Join to discharge – a request to join (connect in parallel) battery modules to discharge the battery;
30 +* Precharge contactor feedback – a signal from precharging contactor feedback loop;
31 +* Main contactor feedback – a signal from main contactor feedback loop;
32 +* Interlock – a signal from interlock loop;
33 +* Power down request – a request to power down the BMS.
34 +
35 +Inversion flags for discrete inputs are configured in the "Signals → Input discrete signals → Inversion" section:
36 +
37 +[[image:1734022225583-740.png||data-xwiki-image-style-alignment="center" data-xwiki-image-style-border="true" height="137" width="600"]]
38 +
39 +The behavior of “KEYRUN” signal can be configured in the "Signals → Input discrete signals → KEYRUN mode" section:
40 +
41 +[[image:1734022225584-474.png||data-xwiki-image-style-alignment="center" data-xwiki-image-style-border="true" height="87" width="600"]]
42 +
43 +The behavior of “CHARGE_ON” signal can be configured in the "Signals → Input discrete signals → CHARGE_ON mode" section:

46 +
47 +In both “KEYRUN mode” and “CHARGE_ON mode” sections:
48 +
49 +* Do nothing – power on device and do nothing;
50 +* Set “Join to discharge” – power on device and set “Join to discharge” signal immediately;
51 +* Set “Join to charge” – power on device and set “Join to charge” signal immediately;
52 +* Set “Discharge request” – power on device and set “Discharge request” signal immediately;
53 +* Set “Charge request” – power on device and set “Charge request” signal immediately.
