Configure Occupancy Based Load Control (OBLC)

Configure Occupancy Based Load Control (OBLC)

Before configuring load control, read the Load Control Overview.

How does load control work?

  1. A user creates a Trigger Group - a group of Trigger Nodes (whose occupancy data will be used to trigger a relay)
  2. A user assigns activation threshold criteria for the Trigger Group
    1. i.e., if any node within that group is in the active occupancy state, or if a percentage of that group are in the active occupancy state
  3. A user configures a Load Control enabled relay device to respond to one or more Trigger Groups, based on specified criteria

Configuring Load Control Devices

  1. Navigate to the Sense Application
  2. Click Load Control
  3. Select New
  4. Provide a descriptive Name for the Load Control Rule

  5. Select the Site and Area
  6. Select the Detection Mode - whether to trigger the relay behavior when the Trigger Groups detect occupancy or vacancy
  7. Configure the Trigger Group(s) of occupancy sensing nodes:
    1. Select one or more Trigger Nodes that will be used to trigger this load
    2. Select the Trigger Criteria - the threshold number of Trigger Nodes that must be in the active occupancy state for the Trigger Group to be active
    3. Click the + button to add additional Trigger Groups
      1. If using multiple Trigger Groups, select whether All or Any of the Trigger Groups should be active before triggering the relay

  8. Select one or more Relay Devices that should be triggered as part of this Load Control rule

  9. Add an optional Timeout - the amount of time for which the trigger node remains active after the node’s group does not sense occupancy - this time is in addition to the timeout of the Trigger Node’s existing Task Tune settings
  10. Select the desired open/close behavior of the device
    1. Typically Open = Off, Closed = On, but that is not the case for all relays. Work with your installer to set this up correctly
  11. Review the relay behavior tooltip explaining how the Load Control will behave

  12. Toggle the Enabled slider to enable or disable the Load Control
  13. Click Save

Info
Trigger Nodes switch between the active and inactive occupancy states based upon the occupancy events detected by the motion sensor as well as the timeout of the Trigger Node’s existing Task Tune settings. For example if a Trigger Group consists of an aisle and all sensors in the aisle have a 5 minute timeout in Task Tune settings, if someone walks down the aisle each node will remain active occupancy state for 5 minutes after occupancy is detected. Thus if the person walks through the aisle and exits in less than the Task Tune timeout of 5 minutes, then all sensors in the aisle would simultaneously be in the active occupancy state for a period of time until the 5 minute Task Tune timeout expires on each individual light.

Alert
If the Gateway governing the Trigger Nodes loses connection with SiteWorx, the associated Load Control will remain in its current state. Once the connection to SiteWorx is restored, the Load Control will return to the correct state once the associated Trigger Node changes state.
