Daylight Harvesting Calibration
Overview
Daylight Harvesting must undergo a one-time calibration procedure to establish a target light level for each fixture in the facility. The procedure establishes a dimming curve for each fixture which is automatically adjusted based on the desired light level outputs set in SiteWorx Tune. Suppose the active light level is later changed in the SiteWorx Tune software (for instance, from an Active Level of 100% to an Active Level of 80%). In that case, the target Daylight Harvesting level will automatically adjust to match the new desired output – no additional calibration is required.
If fixtures are moved, or if capital equipment is moved on the floor, the procedure should be repeated to establish new targets.
Calibration Procedure
Calibration must occur during the overnight hours when it is dark outside. The process consists of SiteWorx automatically taking over control of all lighting sensors and luminaires and overriding them to 100% output with no dimming. Each luminaire will then dim down to 1% and 0% output, then reset to 100% output.
All Tune settings will be saved and reapplied after calibration completes. However, the user cannot make any lighting changes during the calibration process.
The process takes approximately 15 seconds per sensor, so be sure to consider this when selecting a start time. Since users will not have control of the luminaires, which will be dimming down to 0% as part of the calibration, we recommend the facility be unoccupied during the calibration for safety reasons.
Additionally, the following conditions must be met to ensure proper calibration levels:
- Lighting network gateways and luminaires will remain powered during the desired calibration time.
- All luminaires, gateways, and lighting sensors are communicating with SiteWorx.
- The facility is set up in its final configuration - equipment & floor surfaces are installed and product in place (in warehousing applications).
