Connecting the CIM and the Hall Effect Sensor
After connecting cables, on the CIM WebUI, choose Monitoring > CIM System >
Running Parameter > Basic Information, and set Current source. The setting of the
current source must be consistent with the actual Hall effect sensor. For example, if the
Hall effect sensor is 50 A, set Current source to Hall 50 A.
If the Hall current sensor is prepared by the customer, the customer should refer to the
model recommended by Huawei. The rated current of the sensor should be 50 A, 100 A,
and so on, and the corresponding output voltage at rated current should be 4 V. For
example, if the 0–50 A Hall sensor range is chosen, ensure that the sampling current ±50 A
of the Hall current sensor corresponds to ±4 V output voltage.
Connect the CIM to the Hall effect sensor. Table 3-5 lists the mapping between the wiring
terminals and signals. For more details, see the user manual delivered with the iBAT 2.0.
