Sensor Fault Alerts

With 2.01, there is a simplification to Sensor Faults. Sensor Faults are used to detect if there are issues with the data that is coming into the application.
A Sensor Fault Alert is raised when the average value exceeds its threshold limits, this is calculated every hour, and calculates using the last hour of data.
Below are additional details on this type of alert and calculated metrics:
  • Threshold-Based Alert
    • The condition for generating alert is verified every hour and depending upon whether the thresholds are crossed or not, the alerts are generated.
  • Average/Mean Calculation
    • If the mean of the sensor values (calculated hourly for last hour of sensor data) goes below or above the pre-configured threshold for the sensor, a Sensor Fault alert is raised.
    • Severity: The severity level of Sensor Fault Alert is always classified as High.
    • Even if a previous alert triggered by the sensor remains open, another alert would be raised.
  • Data Metrices
    • They are calculated every hour, using the last 24 hours of data.
    • Valid Data
      • Defined as percentage of non-repeated sensor data. (100 – repeated data)
    • Invalid data (Repeated Data)
      • Data points that repeat continuously for at least 10 minutes are marked as repeated. This is defined over any 10-minute window within last 24 hours. The overall percentage of such time windows over the last 24-hours constitutes the repeated data.
The following tabs are available in Sensor Fault Alerts:
  • Overview
  • Trends
Sensor Fault Overview
Overview
In the
Overview
 tab, there are three different sections - Fault Details, Sensor Fault Action, and Work Order.
In the
Fault Details
 section, the user can view the alert details such as Sensor Fault ID, Description, Status, Trigger date, Sensor Name and Description, and Asset/Component Association. The user can also view the breakdown of the Valid and Invalid Data calculations, with definitions as provided above.
NOTE: Click
View History
to view the history of changes that happened in the
Sensor Fault Action
 and
Work Order
 section.
View History
In the
Sensor Fault Action
 section, with appropriate user privileges, the user can change the status of the Sensor Fault Alert Status, Add Comments, and Upload associated files.
The
Work Order Action
 section allows for the manual and automated tracking of the associated Work Order required for the action of the alert. The user can manually create a work order number, change status, and add comments to the work order.
NOTE:
  • The work order is created automatically in the following scenario:
    • If the CMMS integration setup is configured with assets or components mapping and the integration status is set to enabled status.
  • The work order needs to be created manually in the following scenarios:
    • If the CMMS integration setup is configured without asset or component mapping or the integration status is set to disabled status.
    • If the CMMS Integration setup is not configured.
For manual work order creation, perform the following steps:
  • In the
    Work Order Action
     section, click
    Create Work Order
    .
    NOTE: The
    Create Work Order
     is enabled only when the KPI Alert status is set to Investigation status.
  • Work Order No
    : Provide the work order number for the alert.
  • Work Order Status
    : Select the status from the drop-down list.
  • Comments
    : (Optional) Provide the comments for the alert as required.
For automated work order creation using CMMS-Fiix:
In the
Work Order Action
 section, click
Create Work Order
. The "
Work Order request has been successfully initiated for the alert. You will be notified when the work order is created in CMMS
" message is displayed. The work order is set to the initiated stage and it is non-editable.
NOTE: The
Create Work Order
 is enabled only when the KPI Alert status is set to Investigation status.
The work order request for the alert is initiated and sent to CMMS-Fiix. Once the request is acknowledged and the necessary action for the work order request is taken, work order details are updated automatically.
Trends
In the
Trends
 tab, the user can view the Trend at the top and a sparkline view at the bottom. The user can change the date selection by using the selectors of 1/3/6 months, year to date [YTD], 1 year, and all. The user can use the sliding selector at the bottom to change the date selection.
The red horizontal lines indicate the configured Sensor Fault Alert Thresholds Upper Sensor Fault and Lower Sensor Fault.
Hover over the trend chart to view the KPI value with the corresponding date and time details.
