53 +=== Main contactor ===
54 +
55 +The BMS Main X device controls the main contactor. The main contactor is usually placed in the common (minus) battery line for opening the charge and discharge circuits in case of sealing of the charging or discharging contactors.
56 +
57 +The Main contactor algorithm supports the following modes:
58 +
59 +* Always on;
60 +* Automatic, when the main contactor closes by the internal charging and discharging algorithms at the same time with Precharging, Charging, Discharging and Charging/Discharging contactors.
61 +
62 +In “Always on” mode main contactor closes if all the following is true:
63 +
64 +* Other contactors are open;
65 +* There are no errors from the "Errors 1, 2 ..." bitfileds.
66 +
67 +In “Always on” mode main contactor opens if all the following is true:
68 +
69 +* Other contactors are open;
70 +* There is an error from the the "Errors 1, 2 ..." bitfileds.
71 +
72 +In “Automatic” mode, the main contactor closes by internal algorithms at the same time with other contactors.
73 +
74 +To change the parameters of the main contactor, select the "Control → Main contactor" section:
75 +
76 +[[image:1740749605680-464.png||data-xwiki-image-style-alignment="center" data-xwiki-image-style-border="true" height="117" width="800"]]
77 +
78 +In this section:
79 +
80 +* Enable – a flag to enable the main contactor control;
81 +* Algorithm – main contactor control algorithm:
82 +** Always on – contactor is always closed;
83 +** Automatic – contactor closes by internal charge and discharge algorithms;
84 +* Time to keep the contactor closed before closing the others – a time for other contactors to be open after the main contactor is closed, millisecond;
85 +* Delay before opening the contactor – a time which is used to detect conditions for opening the contactor, millisecond;
86 +* Keep the contactor open until the device is restarted – a flag for keeping the main contactor open until the system is reset;
87 +* Errors to open the main contactor – error flags that cause the contactor to open.
88 +
89 +=== Charging status ===
90 +
91 +To change the parameters for generating status signals when charging the battery, select the section “Control → Charging status”:

96 +
97 +* Current corresponding to charging – a current level to set the "Charging current present" signal, A;
98 +* Current corresponding to no charging – a current level to clear the "Charging current present" signal, A.
99 +
100 +=== Discharging status ===
101 +
102 +To change the parameters for generating status signals when discharging the battery, select the section “Control → Discharging status”:

105 +
106 +* Current corresponding to discharging – a current level to set the "Discharging current present" signal, A;
107 +* Current corresponding to no discharging – a current level to clear the "Discharging current present" signal, A.
108 +
109 +=== Precharge ===

114 +
115 +In this section:
116 +
117 +* Precharge current threshold to close the discharging contactor – a current value to ensure that precharge process has finished and it is allowed to close the discharging contactor, A;
118 +* Check voltages before and after contactors to finish precharging – a flag to check the voltages before and after contactors to ensure that precharge process has finished and it is allowed to close the discharging contactor;
119 +* Minimum voltage difference before and after contactors to finish precharging – a minimum voltage difference before and after contactors to ensure precharge process finished, V;
120 +* Number of precharging attempts – maximum number of precharging attempts before setting the "Precharge error";
121 +* Delay before current measurement – a delay before first current measurement after closing precharge, millisecond;
122 +* Precharge time – a duration of closing the precharge contactor before closing the discharging contactor, millisecond;
123 +* Relaxation between attempts – a duration between precharge attempts, millisecond;
124 +* Check the power dissipated in the preacharge resistor - a flag to enable the calculation of power dissipated in precharge resistor;
125 +* Precharge resistor resistance, Ohm;
126 +* Maximum allowable power dissipated in the resistor, W;
127 +* Delay before setting the "Precharge error" when checking power, millisecond;
128 +* Delay before clearing the "Precharge error", second;
129 +* Lock – a flag to block the error until the device is restarted.
130 +
131 +“Precharge error” generation conditions if any of the following is true:
132 +
133 +* the precharge current does not decrease during the "Precharge time" after "Number of precharging attempts";
134 +* voltages before and after contactors are not equal during the "Precharge time" after "Number of precharging attempts";
135 +* power dissipated on the precharge resistor is above the maximum value during the “Delay before setting the 'Precharge error' when checking power” time.
136 +
137 +Behavior of contactors at “Precharge error” is configured in corresponding contactor settings!
