Equipment FDD gathers data from sensors and equipment, and applies complex algorithms to uncover potential problems alerting staff to an impending issue and identifying the cause. Visual displays are provided to assist technicians identify a preventative solution.
Fault notification
OBEM notifies users with all the latest faults using the bell notification available throughout the application, including on the setup screen.
- Click the bell icon to see all faults that are an indicator of fault notification.
- A number on the bell icon represents all unacknowledged faults occurring in the last 30 days.
- A filter is available to sort the faults in order or priority.
- Click the information icon to view the portfolio, location, and equipment associated with the fault.
- Click the acknowledge icon to indicate the fault has been acknowledged. This removes the fault from the notification screen.
Fault dashboards
Fault dashboards are integrated into the system to help the user quickly and easily identify spaces that are affected by faults. Both fault counts and fault duration are displayed. The percentage deviation provides an easy view of the fault trend compared to last period. Fault dashboards include the following features:
- A complete view for the user to see the faults and prioritize them
- Fault Categorization:
- Each equipment fault is categorized for comfort, energy, maintenance, miscellaneous, or compliance. The categories are available for both global and custom rules.
- Categorical distinguishing of faults:
- Fault by Space: Gives fault count and duration at the selected space level
- Fault By Equipment Category: Gives fault count and duration at the selected equipment category level
- Fault by Type: Gives fault count and duration by fault types and names
- Fault by Priority: Gives fault a color depending on the priority of the fault
- Easy navigation to get to the fault root cause with the space to equipment link
- Equipment to points causing fault view
- Details of faults at varying levels by floor, wing, room, or meter
- A view of top five faults
- A view of faults trend
- A search function is available to search for equipment and fault names
- Click on a fault to view the following information:
- A single fault has multiple diagnostics. Each diagnostic runs on an equation and its duration is calculated separately. The diagnostic with the highest duration is shown at the top to aid the user in deciding the most probable diagnostic.
- Each diagnostic has multiple reasons mapped. These appear when a user clicks on a particular diagnostic.
- The equipment relationship gives the fault status of the parent and child equipment in a color code of red, for fault, and green, for no fault.
- Click an equipment to view the FDD dashboard of the respective equipment.
System faults
Run smart rules against a hierarchy of equipment or different systems. Write custom rules that span points across multiple pieces of equipment, devices, or meters. For example, if multiple pieces of equipment are working together to serve a building, write custom rules to identify faults that impact an entire system rather than just a piece of equipment in isolation. As another example, set a rule for zones of VAV boxes instead of for every VAV box.
The rule is as follows:
- If the average of VAV zone temp 1, 2, 3, 4, 5 < 65 degrees then create a fault
- No need to assign equipment because its specifically tagged in the rule
- Result: when the rule is true, the logic triggers one fault for all the VAV boxes
- Quickly check larger data sets and then drill into the targeted data that makes up the system
Fault backdated reprocessing
Request for backdated faults. Normally faults are triggered from the day they are configured. With this feature, users can view the faults for a historical period. Some faults appear as a result of reprocessing and some faults disappear as a result of the reprocessing.
