Understanding Light Profiles v4.6

A lighting profile determines the fixture's light level settings. The sensor uses the light levels along with the time of day, week day, and time to control fixtures light levels.

Viewing a Profile

To view a profile, select a Profile Instance from the Profile Templates in the left navigation panel and click Settings>Edit.

Periods of a Day and Weekdays

The profiles support four periods of the day:

1. Morning
2. Day
3. Evening, and
4. Night.

The settings to set start times for periods of each day are shown below. 

Morning – A typical Morning period would be from 6 am to 7:30 am. The Morning period comes after Night.

Day – A typical Day period would be from 7:30 am to 5:30 pm. The Day may be set to start with the sunrise.

Evening–A typical Evening would be from 5:30 pm to 8:30 pm. The Evening period may be set to start with sunset.

Night– A typical Night period would be from 8:30 pm to 6 am. 

Weekdays– The configuration allows any day to be classified as a weekday or weekend day.   

Profile Basic Attributes

For each period of the day, the profile has the following weekday and weekend settings.

1. Min light level when on (0-100) (%) – The minimum level between 0 and 100 percent to set the light. Typically, this should either be zero for a private office or around 20 for an open office when occupants are present. Setting the value to 0 allows light to be turned completely off when no occupant is present or  ambient light is abundant. The value of this attribute has two purposes, which are:
   
   • • • The setting below a value results in the bulb flickering or not illuminating. If this occurs, then the value should be increased until these behaviors no longer occur.
         NOTE:  The Dim and linger's value (found in the Advanced Profile) should also have the same value.
       • A value greater than zero prohibits the fixture from turning off the lights, which is appropriate for security lights or for locations where turning the lights on and off would distract occupants. For example, in an open office environment, the min level should be set greater than zero during working hours, so the lights do not turn off. However, during periods when only the cleaning staff may be present, it would be appropriate to set the value to zero.
2. Max light level when on (0-100) (%) – The maximum level between 0 and 100 percent to set the light. This is the value that can be reduced when there is too much illumination by the light. Typically, the value would be between 60 and 80, which should be reduced to no less than 25 or 30. The value of this field restricts the maximum light level. Typically, during the lighting design of a building, the usage of the building is not known. Also, over time as bulbs age, the light output slowly decreases. There also may be some occupants who are adversely affected by bright lights. Thus, use this attribute to reduce the light level to an appropriate value. Note that by reducing the value, energy will be saved.
3. Ramp-up time (0-10) (sec) – The length of time to change a light that is off to its required light level value. For example, when the value is 10, a light that is off will be brought up to the needed light level over 10 seconds when it is turned on. Note: During override commands issued by an API call or BACnet, the command will take effect after the ramp-up time set in the profile ends.
4. Active motion window (1-200) (min)– The length of time to hold a light on after motion has not been detected. When it is expected that the lights should be on during working hours, the value should be longer, such as 15 minutes. During other times, specify a shorter length, such as 3 minutes. When the occupants under the fixture are still, the value may be increased to a longer duration, such as 30 minutes, to reduce the number of times the light level is reduced. Note that when Title 24 for a site is enabled, the Active Motion window must be set to less than 20 minutes. The shorter the Active Motion window, the more energy is saved. 
5. Motion sensitivity (0-10) – Determines a sensor’s sensitivity to continuous motion to detect occupancy. Setting the value to 0 will cause the fixture to behave as if an occupant is always present, such as an area that needs to be continuously lit at night. The default value of 1 causes the fixtures to be more reactive to motion. Specify a higher value for fixtures in open offices to ignore passersby in open corridors. 
6. Ambient sensitivity (0-10) – Determines a sensor’s sensitivity to ambient light. Determines if the light will be dimmed due to ambient light. The value 0 means that the light will not be dimmed; the sensor will not react to ambient light. The value 10 indicates that the light is most sensitive to ambient light. Daylight harvesting mode is most effective when this value is set to 10, so the lights can either turn to the minimum light level or switch off depending on the value set in the Min. light level column for that period. See Enabling Daylight Harvesting.
   
   

   Advanced Profile 

   Note that there are four additional settings for ambient light in the Advanced Lighting profile menu shown below, which control how often and how much the light levels may change. These values need not be changed, but if you would like to tweak the values, contact Enlighted Support for assistance.

   

• Adjust fixture light levels when ambient light levels drop – The drop (5 – 25) (%) and rise (5 – 25) (%) is the percentage change of the ambient light that is needed to trigger a change in the light level.
• Only change fixture light level after the ambient light level is stable– Time in seconds to wait for ambient light changes to be stable before changing the fixture light level. A typical value is 10 seconds. Larger values slow down the reaction to changes in ambient light.
• Change fixture light level due to change in ambient light level no more than once – Length of time in minutes to wait before the fixture light level can be changed due to a change in the ambient light level. This is to avoid rapid cycling in fixture light levels due to passing clouds, which irritates occupants. A typical value is 10 minutes.
• Dim and linger – Linger light level before off (0 - 25) (%) – The fixture's light level before turning off. When turning a light off due to lack of occupancy, the light fixture will first be set at this level for the length of time specified in this field and then turned off.
  Linger time before off (0 – 600) (sec) – The time in seconds to keep the fixture on before turning it off. This field is used to specify the behavior before turning off the light due to a lack of occupancy.
• Fixture initially turns on –The fixture turns on at 50% for 5 seconds before adjusting the lights based on the profile.
  
• Background Light level to 50%- Enable this field to set the background light level to 50% of the profile max when there is no motion.
• Highbay –Enter 1 to enable the lighting profile for Highbay sensors mounted above 25' else enter 0.
  
• Motion Threshold– The following are some possible reasons to modify the values of this field.
  
  • • The lights turn off even when there are occupants present. 
    • The lights turn on when passersby (transient) motion is detected. 
    • The lights turn on due to false triggers of motion.  
    • The lights delay too long before turning on. 
  • Refer to the article Effect of Motion Sensitivity, Active Motion Window, Motion Threshold on the Light Level due to Motion.
• Holiday Override Profile– To schedule Holiday Overrides, select an override from the Holiday Override Profile drop-down box. For details, refer to the article Configure Demand Response and Holiday Behavior.
• Daylight Harvesting – The following Profile attributes settings are for Daylight Harvesting. For a detailed description, refer to the article Daylight Harvesting.
  
  
  • • Enable Daylight Harvesting Override mode– Select this option to enable daylight harvesting. 
    • Allow Daylight Harvesting to dim lights below the minimum light level –Select this option for the lights to turn off. Daylight harvesting override mode is thus enabled, turning the lights off rather than merely dimming them to 15% of the min. light level specified in the lighting profile. Refer to the article Daylight Harvesting.
    • At a time period change when there is no motion, allow a change in minimum light level to raise light levels –Select this option to turn on the lights to the profile minimum value at the beginning of the profile period. 
    • When motion is detected, ramp up to the target ambient light level over 3 seconds – Select this option to turn on the lights to the Ambient Light Level instead of the Max light level when motion is detected.

Create or Edit Light Profile v4.6

Overview

Manage is shipped with predefined profile templates; each template contains a single profile instance for
the most common areas and rooms in buildings. The two additional templates shipped are Custom1 and Custom 2, that can be renamed and used for organization-specific use cases. 

Only system and facility administrators can create profile templates and instances, but users can edit the light profile settings. Profile templates and instances are predefined values that determine the light level settings of a fixture; you can modify the values as per your requirement.

For example, you can create a template for standard classrooms and large lecture rooms in a university. Then instances can be created and edited based on needed behavior to match use cases, as shown below. However, the default template cannot be edited, it can only be viewed or exported.

Effect of Motion Sensitivity, Active Motion Window, Motion Threshold on the Light Level due to Motion v4.6

This article describes the effects of the three settings that affect the changing of the light level due to occupants' motion. There are several possible reasons to modify the values to control the behavior of lights, as explained below:

• The lights turn off even when there are occupants present. 
• The lights turn on when passersby (transient) motion is detected. 
• The lights turn on due to false triggers of motion.  
• The lights delay too long before turning on. 
• Lights stay on for a long time after the last occupant has left the area. 
• Title 24 Enabled. 

The three settings that influence the light levels are

1. Motion Sensitivity: The sensor's sensitivity to detect occupancy due to motion. 
2. Active Motion Window: The length of time to hold a light on after motion has not been detected.
3. Motion Threshold (Advanced): The threshold between 1 (min) and 10 (max) for detecting motion.

Refer to Understanding Profile Basic Attributes for a description of these fields.

To view the Active Motion Window or Motion sensitivity for a sensor, double-click a sensor on the floor plan, and select the Profile tab from the Fixture Details window.   

Scroll down and select Advanced to view Motion Threshold.

There are several possible reasons to modify the values:

• The lights turn off even when there are occupants present. 

  This is reduced by setting the value of motion sensitivity to 1 and increasing the active motion window value. These changes cause the fixtures to be more reactive to motion. In extreme cases, the value of motion sensitivity can be set to 0, which will behave as if an occupant is always present.

• The lights turn on when passersby (transient) motion is detected. 

  This is reduced by increasing the value of motion sensitivity. Also, the value of ramp-up time can be increased so that when lights are turned on, the light level increases over a longer time and reduces the distraction.

• The lights turn on due to false triggers of motion.  

  This can be due to heat from a printer located beneath the fixture or air from a vent. A value should be selected between 1 and 10. The value 1 is the lowest threshold, and higher values raise the threshold. Thus, if false triggers are occurring, then the value should be raised.

• The lights delay too long before turning on. 

  This is due to a high value for motion sensitivity. Reducing the value will shorten the time but may result in lights turning on due to transient motion detection. Note that there is an additional attribute to tune sensitivity to motion.

• Lights stay on for a long time after the last occupant has left the area. 

  This is the result of having a large value for the active motion window. Reducing the value will shorten the time the lights are on when  no occupants are present but may result in the lights turning off when very still occupants are present.

• Title 24 Enabled. 

  • Min light level when on (0-50)(%) - The minimum light level set should be greater than 0 percent and less ,than 50 percent.
  • Max light level when on (30-100)(%) - The maximum light level set should be greater than 30 percent and less than 100 percent.
  • Active Motion - Must be set to less than 20 minutes.

As you can see, there are potentially conflicting trade-offs. Another approach is to physically relocate the sensor slightly to change the occupancy sensor's motion detection.

Background Lighting v4.6

Background lighting saves energy by turning on the lights to profile max only when an area or space is occupied. It relies on a group of sensors using the same profile and being in the same motion group. It uses a combination of the sensors' profile max light level and background light level of the motion group enabled in the Advanced Profile.

In legacy lighting control, the profile has two light levels: min and max light level. When there is no occupancy, the sensor controlling the fixture sets it to the min. light level, and when the sensor detects motion, the lights go to the profile max. 

Background lighting allows any sensor in the group to control the light levels in the area. When a person enters a room, background lighting turns on all lights in the area to the profile max, providing sufficient lighting in the area. As the person prepares to stay and work at the desk, the sensors directly above the person raise their light levels to the profile max, while the remaining lights in the area continue to maintain their background light levels. 

When the person leaves the room, and after the Active Motion Window times out, the lights go down to the background light level (50% of the profile max). The lights stay at background light levels as long as there is no motion for the time specified in the Advanced Profile, after which, the lights go down to the profile min light level. 

To enable background lighting,

1. Click on Profile Templates in the left panel to display the list of available profiles.
2. Select the required profile instance.
3. Scroll down and click the Advanced tab. The Advanced Profile window is displayed. 
4. Check the box to set Background Light level to 50% of the profile max.
5. Specify a time between 1 minute and 120 minutes for the lights to go down to the background light level after the Active Motion window times out.
6. Scroll up and click the Update button to apply the changes.
7. Assign the profile to the group of sensors controlling background lighting.

  

Daylight Harvesting Overview v4.6

In a facility with skylights, windows, sidelights, you have available daylight, which varies according to the day's time. As daylight levels increase, light levels can automatically decrease to save energy. By enabling Daylight Harvesting, you can take full advantage of ambient sensitivity to manage light levels. The Target Ambient Light Level, also called Ambient Threshold, determines the light target levels. The following description explains the fields that control and configure Daylight Harvesting. 

Things to know:

• Daylight groups, which provide a uniform dim level across a group of fixtures for improved aesthetics, tend to adjust fixture light levels more slowly over minutes.
• Daylight Harvesting fixtures adjust light levels quite fast in seconds in comparison to Daylight groups. See the recommendation about how to control the pace of a Daylight Harvesting fixture changing its light level in response to Daylight.

Target Ambient Light Level

The Target Ambient Reading that the sensor attempts to achieve by adjusting its light level.

The Target Ambient Light Level is determined and set up during the initial set up of the system. This command should only be used under the direction of Enlighted field support engineers. The procedure for obtaining the best value is to perform this command when there is no ambient light (such as at night) with all the lights set to full-on. You can also set the Target Ambient Light Level for selected sensors. The value can be set manually, or the sensor’s current ambient value can be set to be the target ambient value. Contact Enlighted Customer Support to determine or set this value or refer to the Determine and Set Target Ambient Light Level article.

Ambient Reading

The ambient light level measured by the sensor.

Ambient Sensitivity

Determines a sensor’s sensitivity to light, and it ranges between 0-10.  For Daylight Harvesting to have maximum effect, it is recommended to set the ambient sensitivity to a higher value in the corresponding lighting profile. Ambient sensitivity value, which determines a sensor’s sensitivity to light, ranges between 0-10. The value 0 means that the light will not be dimmed, and value 10 means that the light is most sensitive to ambient light. Daylight Harvesting will be most effective when the value is 10.

Daylight Harvesting

Lighting Profiles can be different over different periods of the day. The Enlighted system allows for four profile periods:

• Morning,
• Day,
• Evening, and
• Night.

Each profile period has individual Min Light Level and Max. Light Level settings and Ambient Sensitivity settings (among other settings).

The values in the lighting profile specify the Min. light level when on (0-100%) that is applied to a fixture. Normally, the light is never lowered below the profile minimum. For example, if the minimum light level is set to 15% in the profile, the lights will never turn off but will be dimmed to 15% of lighting. However, when there is sufficient daylight, the lights can be turned off and not merely dimmed to the minimum value.

 

For daylight harvesting to be active, the option

• Enable Daylight Harvesting Override mode in the Profiles Advanced menu must be checked. By default, this will be unchecked. See Configuring Daylight Harvesting v4.6 for a step-by-step procedure.

To Turn Lights Off During Daylight Harvesting,

Selecting the Allow Daylight Harvesting to dim lights below the minimum light level overrides the Daylight harvesting mode, turning the lights off rather than merely dimming them to 15% of the min. light level specified in the lighting profile. 

Override Settings for Min. Light (Profile Minimum Override)

As the system transitions between profiles, the profile setting for minimum light is not automatically applied to maximize energy savings. The lighting profile setting, and occupancy state determine whether the light is turned on or dimmed.

For example, if the lights are off because there is no occupancy detected, then the lights will continue to be off as the system moves from the day to evening profile. This is not desirable for outdoor lights or in company lobbies because the lights should turn on irrespective of occupancy, for safety or business reasons at certain times. For example, in a parking garage or company lobby, the lights should turn on to profile minimum value even if no one is there -- for safety reasons.

In the above example, the light needs to be turned on to profile minimum value at the beginning of the profile period. For this option to be effective, enable the option At a time period change when there is no motion, allow a change in minimum light level to raise light levels as shown below.

You must also enable this option (At a time period...light levels) when the evening period is set based on the astronomical clock. See Setting Advanced Attributes when Astronomical Clock is Set.

Override Settings for Max Light (Profile Maximum Override)

By default, when daylight harvesting is active, the light level ramps to the Max light level, and decreases to the Ambient Light Level within the ramp-up time set in the profile when motion is detected.

If you would like lights to go to the Ambient Light Level instead of the Max light level when motion is detected, check the option as shown below in the Advanced Settings.

When this option is selected, the light level goes to the Target Ambient Light Level over three seconds when motion is detected. The ramp-up time in the profile is overridden and set to three seconds. If there is sufficient daylight, the lights may not turn on when motion is detected, thus increasing energy savings.

Lights Dimming Process

The dimming process can take up to 30s or a minute at an individual fixture. The Daylight fixtures adjust light levels quite fast in seconds compared to the Daylight groups, that change light levels more slowly over minutes. Generally, the lights will brighten faster than they will dim. In some cases, with motion and complete darkness, lights may brighten immediately.

Setting individual daylight harvesting (not daylight groups) requires adjusting two settings in the advanced profile setting to get a real-time reaction of dimming lights for a fixture. Select a fixture from the floor plan and double-click to view the Fixture Details window. Select the Profile tab and scroll down to view the Advanced menu. 

The two settings shown above work together and changing them too drastically can lead to discomfort for occupants. Enlighted recommends maintaining a time period of 10 seconds and 10 minutes for a consistent light level before making a change. While customers may desire a faster response, Enlighted prioritizes consistent and gradual light adjustments over rapid changes to ensure a smoother experience for users.

To configure Daylight Harvesting for your organization, refer to the article Configuring Daylight Harvesting v4.6.

 

Configure Daylight Harvesting v4.6

By enabling Daylight Harvesting, you can take full advantage of ambient sensitivity to manage light levels. To enable Daylight Harvesting Override mode,

1. Select a profile in the Profile Templates navigation tree.

2. Select the required profile instance and click the Edit button.

In the resulting Edit Profile screen,

Step 1: For each weekday or weekend setting, set the Min. light level when on (0-100%) to a value greater than zero.
Step 2: Set Ambient Sensitivity to 10. The higher value ‘10’ means that the light is most sensitive to ambient light.

Step 3: Scroll all the way down until the >>Advanced option is seen and click the >>Advanced option to expand the screen.
Step 4: Check both options: Enable Daylight Harvesting in Override Mode and Allow daylight harvesting to dim lights below the minimum light level (See Daylight Harvesting for a description of these options).

Step 5: Scroll to the top and click Update.

The Daylight Harvesting override mode is thus enabled, turning the lights off rather than merely dimming them to 15% of the min. light level specified in the lighting profile.

Also, note that if the options are checked as shown below in the Advanced settings, it will override the profile min. light level and max. light level settings. (See Daylight Harvesting for a description of these options).

Configure Demand Response and Holiday Behavior v4.6

• Overview
• Points to remember:
• Configuring DR and Holiday Behavior
• Demand Response Modifier - Applicable for sensor firmware v5.14 and above
• FAQs:

Overview

Demand Response (DR) and Holiday override contribute to energy load reduction and savings during peak demand time and public holidays. This section helps you configure a Demand Response (DR) and Holiday override event to meet energy load reduction during peak hours. 

End-users who are set up by the utility as a DR participating company will receive a notification from the utility of the DR event and their Manage Administrator will schedule the event in Manage.  If that company is participating in Open Automated Demand Response, then Manage will need to be registered on the utilities Open ADR Server.  Once done, the Open ADR server will initiate the DR event directly with Manage and there is no need for the manual process above.  An internet connection between Manage and the Open ADR server will be necessary to support this feature. 

Caution:

For the Override to take effect, please note the values entered in the Override: 'Max. Light level when on (0-100%)' column must be lower (<) than the Period: 'Max. Light level when on (0-100%) value. Otherwise, the Override will not take effect.

Points to remember:

When DR is in effect, the Maximum light levels are adjusted to the DR override specified maximum.

• If a light is on and is above the DR override max. level, it will immediately transition to the new DR Override max. level.
• If a light is on and is below the DR max. level, it will not change its level.
• If a light is off, it will remain off and turn on to the level specified in its profile, or to the DR max. level, whichever is less, for the duration of the DR Override.
  • • Auto On lights will turn on based on the light profile.
    • Manual On lights will turn on when the ERC button is pressed.
• Demand Response Modifier: Checking the Top-end Trim Max Light Level Limit will apply the Override Max Light levels to all fixtures, including Daylight Harvest, Motion, and Switch Groups uniformly until the DR Event ends. Once the DR event ends, the fixture light levels will return to their normal profile light levels. Changing fixture light levels in the profile settings and using the ERC switch to adjust light levels will not be possible during a DR event. Refer to the Demand Response Modifier section for further details.

Configuring DR and Holiday Behavior

To configure DR and holiday behavior,

Step 1: Select a profile name in the Profile Template tree from the left panel and click Edit. 

Step 2: In the Edit Profile screen displayed, browse to the Override Profiles section.

• DR —  Override 1, Override 2, Override 3, and Override 4 represent DR overrides.
• Holiday Behavior — Override 5, Override 6, Override 7, and Override 8 represent Holiday behavior override events.

Step 3: In the Override Profiles section, enter light level values for each DR override.

Caution: The values in the columns Override: 'Max. Light level when on (0-100%)' must be lower (<) than the Period: 'Max. Light level when on (0-100%) value for the override to take effect.

Step 4: Scroll to the Advanced section.

• In the Demand Response Behavior box, for each DR Level, select an override profile from the drop-down box.

• Select an override from the Holiday Override Profile drop-down box in the General Behavior window to schedule Holiday Overrides.

Step 5: Scroll to the top right corner of the page, click Update to save the override profiles for DR and Holiday behavior. These configurations will take around 10 to 15 minutes to be pushed to the sensors.

The screen below details all the above steps.

Refer to the article Push Profile Update to a Sensor to verify that the profile has been pushed to a sensor.

To schedule a DR, refer to Scheduling Demand Response and Holiday Overrides.

Demand Response Modifier  

The Demand Response Modifier feature has been included starting with Manage v4.6 and Sensor Firmware v5.14 and above.

The earlier versions of the Manage Demand Response (DR) feature did not meet the 2022 Title 24 CA updates that took effect on Jan.1, 2023, or similar energy code changes.  

The DR Modifier will limit the maximum Light Level allowed during the DR Event to the maximum light level set by the Electrical Utility and in the Manage UI. This DR Modifier light level limit will apply to all light fixtures, as well as to Daylight Harvest, Motion, and Switch Groups uniformly until the DR Event ends. Once the DR event ends, the fixture light levels will return to their normal profile light levels. 

Selecting the box Top-end Trim Max Light Level Limit applies the Max. Light Level to the fixtures during a DR Event. The Max Light output will not exceed this limit until the DR event ends, thus, meeting Title 24, 2022, or similar energy code requirements. 

FAQs:

1. Can Demand Response be configured with EMC Install?

   Yes. Demand Response can be configured with EMC. Demand Response is a predefined override profile within Manage, accessible across all Manage deployments.
   
   

2. Can I adjust a Demand Response (DR) Override lighting profile during a Demand Response event and have the changes take effect within 5 minutes.

   Yes. When a scheduled DR event is active, you can adjust fixture profile parameters in the override profile, with changes taking up to five minutes to take effect. To modify values during an active DR event, go to Profile Templates, select the fixture profile, and update the lighting values.
   See: Scheduling a DR Event, Modifying Values of a Profile.
   
   

3. How exactly does a utility send DR command to Manage?

   End-users set up by the utility as a DR participating company will receive a notification from the utility of the DR event, and their Manage Administrator will schedule the event in Manage.  If that company participates in Open Automated Demand Response, then Manage must be registered on the utilities Open ADR Server.  Once done, the Open ADR server will initiate the DR event directly with Manage, and there is no need for the manual process above.  An internet connection between Manage and the Open ADR server will be necessary to support this feature.
