Custom Sensor Configuration Details

If the sensor does not meet any standard characteristics of the available sensors, you can select the Type as Custom Sensor and set its characteristics. There are three type of custom sensor available Current, Voltage and Resistive

To configure custom sensor:

  1. Navigate to BacnetNetwork > IrmBacnetDevice > IRM Program > double click the Control Manager.
  2. Click on the Custom Sensor Details and configure the fields
  3.  

    The following table describes the configuration properties and their definitions.

    Name

    Definition

    Enable

    Select True to enable the selected custom sensor configuration.

    Sensor Name

    Enter the name of the sensor

    Sensor Type

    Select sensor Input (Current, Voltage and Resistive) from the Sensor Type drop-down menu.

    Sub Type

    Select a sensor type from the Sub Type drop-down menu.

    Specification Unit

    Specification Unit option in the drop-down menu depends upon the Data Type selected while configuring the details on the Add window.

    Linearization

    The Linearization field, where the linearization points are provided to define the characteristics of the sensor. The Tabular Conversion Dialog window is displayed.

    Sensor Low Limit

    Lower limit in the Low Limit field.

    Sensor High Limit

    Upper limit in the High Limit field

    Sensor Reading Output Limits

    Select the value for Sensor Reading Output Limits from the respective drop-down menus. Sensor Readings Outside Limit,

    • The Value is Invalid outside High Limit option is selected, when output crosses the limit, the output becomes invalid.
    • The Clamp Value as High and Low Limits option is selected and if output crosses the high limit or low limit, the output is clamped to Low or High Limit and it doesn’t become invalid
    • The Continue Linearization Without Clamp option selected, the user wants continue sensor reading outside the High limit

    Offset

    Offset is the precision limit of the curve

    Validation Text

    This field verifies the configuration of custom sensor, if any of the field not configured it will display a message.

  4. Select Sensor Type as Current or Resistive or Voltage.
  5. Configure the Specification Unit option in the drop-down menu depends upon the Data Type selected while configuring the details on the Add window.
  6. Click next to the Linearization field, where the linearization points are provided to define the characteristics of the sensor. The Tabular Conversion Dialog window is displayed.

  7. Click Add
  8. Enter the sensor current value for the electrical signal in the Source field and enter the corresponding value of the parameter which is being sensed in the Result field.

    Enter the low and high limit sensor values in the Sensor Low Limit (Sensor value at 0 mA) and Sensor High Limit (Sensor value at 20mA) fields respectively as per Sensor Data Sheet.

    Similarly add and enter value for the sensor resistance value and sensor voltage value for Resistance and Voltage input.

  9. Select the value for Sensor Reading Output Limits from the respective drop-down menus.
  10. Enter the Offset value.
  11. Click Save after entering the required details.

If any of fields not configured, the Validation text will display a message.
