This article is about general and Fault Detection and Diagnostic for Lighting Control System used in Integrated Automation System or Building Automation System.
Lighting Control System Fault Detection and Diagnostic
-
Bad Energy Data
- Description:
- Find periods for at least a duration when data contains values outside of low and high limits or the data is shown as “not a number” (NaN). Fault dependencies and associated scenarios include the following;
- All data will be imported into the SCMS ‘as is’ from its existing system.
- Requirements
- Consumption or Demand Point: Any point that has consumption or demand type units
- Description:
-
Double Dipping Data
- Description
- Finds periods for at least a duration when a point’s history contains two or more data points within a leeway of an interval. Fault dependencies and associated scenarios include the following;
- All data will be imported into the SCMS ‘as is’ from its existing system.
- Requirements
- Consumption or Demand Point: Any point that has consumption or demand type units
- Description
-
Lights Running During Unoccupied Hours
- Description:
- Generates a fault when lights are running during unoccupied hours and an associated occupancy sensor has not detected motion therein. Fault dependencies and associated scenarios include the following;
- Periods are only found when the local occupancy sensor has not detected motion for a defined length of time.
- The lighting is scheduled to remain off.
- Requirements:
- Interior Lighting: This rule is applied to only interior lighting
- Lighting Schedule: Occupied/Unoccupied
- Light(s) Status or Light(s) Command: Light(s) on/off status
- Lighting Level: Measured via Multi-Sensor
- Occupancy Sensor Status: Motion Detected/Not Detected.
- Occupancy Sensor Timer: 30 Mins (Adj.)
- Description:
-
Lights Not Running During Occupied Hours
- Description:
- Generates a fault when lights are not running during occupied hours and an associated occupancy sensor has detected motion therein. Fault dependencies and associated scenarios include the following;
- Periods are only found when the local occupancy sensor has detected motion for a defined length of time.
- The lighting is scheduled to remain on.
- Requirements:
- Interior Lighting: This rule is applied to only interior lighting
- Lighting Schedule: Occupied/Unoccupied
- Light(s) Status or Light(s) Command: Light(s) on/off status
- Lighting Level: Measured via Multi-Sensor
- Occupancy Sensor Status: Motion Detected/Not Detected.
- Description:
-
Lights Not Dimming During Daylight Harvesting
- Description:
- Finds periods when the lighting level exceeds the zone setpoint(s) by a threshold for a longer than a duration. Fault dependencies and associated scenarios include the following;
- Periods are only found when the daylight multi sensor initiates light harvesting.
- The lighting is scheduled to remain on.
- Requirements:
- Interior Lighting: This rule is applied to only interior lighting
- Light(s) Status or Light(s) Command: Light(s) on/off status
- Lighting Level: Measured via Multi-Sensor
- Lighting Level Dimming Status: Dimming status (%)
- Lighting Schedule: Occupied/Unoccupied
- Description:
-
Missing Data
- Description
- Finds periods for at least a duration when a record’s history contains zero data points within a leeway of an interval. Fault dependencies and associated scenarios include the following;
- All data will be imported into the SCMS ‘as is’ from its existing system.
- Requirements
- Consumption or Demand Point: Any point that has consumption or demand type units
- Description
-
Sensor Failure
- Description:
- Finds periods over a duration when a sensor does not change by a threshold for a 24-hour period and equipment is running.
- Requirements:
- Sensor: Any numerical data point from occupancy sensors, daylight sensors and fixture ballasts.
- Description:
