Load Profiles

A Load Profile adjusts certain settings within each dimmer channel which tailors the dimming behavior to improve the end to end dimming experience.

Inbuilt Load Profiles and Inbuilt Dimming Curve, have the pre configured settings which cannot be modified. If the acceptable results cannot be realized with the load being used, the settings are customized and applied to a dimmer channel.

A custom file is allowed to be saved and used within other channels of the dimmer and also shared across other compatible dimmer devices.

In inbuilt, default dimmer channel profile is selected to be the most universal. There are 4 user-configurable dimmer channel profiles. Each channel can be assigned to any one of these 5 profiles. In each case there is a improvement for the light source behavior during dimming, the load profile can be adjusted by the SpaceLogic C-Bus Commission software.

The SpaceLogic C-Bus Commission software enables:

  • The customization of the load profiles per channel

  • 4 user configurable profile per channel/device

  • Saving and sharing of endless load profiles for future project uses

  • Provides guidance for starting point for adjusting the parameters for the most known loads

    • LED Lighting (TE Dimmable)

    • LED Lighting (LE Dimmable)

    • Electronic Transformer (TE Dimmable)

    • Electronic Transformer (LE Dimmable)

    • Incandescent Lighting (TE Preferred)

    • Incandescent Lighting (LE)

    • Sweep Fan

    • Exhaust Fan

NOTE: For future use, SpaceLogic C-Bus Commission enables saving, uploading or sharing of load profile files which includes the following :
  • Load Brand

  • Load Model

  • Load Quantity

  • Custom notes associated with the load

  • Dimming Setting which include the following:

Minimum Brightness: Sets the level where the load operates or is visibly On.

Maximum Brightness: Sets the level where the load exhibits no further change in brightness or output.

Soft Turn On: Sets the role of change for Instant Ramps. The value is the time taken to transit from Off to Maximum Brightness. This value can also affect the timing of C-Bus Ramps between levels and the output of a dimming curve, which is set to 1 second or less.

Soft Turn Off: Sets the role of change for Instant Ramps. The value is the time taken to transit from Off to ON.

Kickstart

Some types of loads have problems starting at low conduction/brightness settings. This shows up as a lamp taking a long time to turn on when turned on at a low setting, or taking along time to respond and they suddenly turning on at a higher level when ramped up slowly from off.

In the case of a motor such as a sweep fan, it might take a long time to start moving or not move at all at low settings.

The Kickstart is a feature which, when enabled, uses a higher brightness setting for a short amount of time when transitioning from off to on, which improves the startup behavior of loads with these kinds of problem.

When Kickstart is enabled, each time the channel is turned on, if the level is less than the "Kickstart Brightness", the channel will fade to the "Kickstart Brightness" setting over the duration set by the "Kickstart Turn On" setting. It will then stay at the Kickstart Brightness setting for the duration set by the "Kickstart Duration", and then fade to the current level over the duration set by the "Kickstart Recovery" setting.

Kickstart Duration: When enabled, sets the duration to maintain the Kickstart Brightness level before recovering to a lower level if set.

Kickstart Brightness: When enabled, sets the dimmer Kickstart Minimum Brightness level before when transition from Off to On (at any level).

Kickstart Turn On: When enabled, sets the time in which the Kickstart Brightness level is applied to the load. A value of 10 ms is a Fast or Hard Start (same as a switch). This value is recommended to be set to Fast between 0.010 ton 0.100 seconds.

Kickstart Recovery: When enabled, sets the time taken at the end of the Kickstart duration to transition from the Kickstart Brightness level to the currently set level of the load.

If the set level is less than the Kickstart Brightness level, this value is set to Slow to achieve a smooth unnoticeable transition at the end of the kickstart.
