  • Load Profiling: How it Works

    Full Profile: Seven-point sampling. First step is to travel to the nearest Limit (top or bottom). Nothing is actually done here, just waiting until you stop. Once you stop, the hoist measures the distance between this point and the opposite soft limit and establishes seven equidistant sample points. The screen instructions direct you to travel to the opposite Limit. During this traverse, the hoist will take a load sample each time it passes through the previously established points.  Once you stop at the second extreme, the hoist measures the distance between this point and the opposite soft limit and establishes another seven equidistant sample points.  The screen instructions tell you to travel back to the first Limit. During this last traverse the hoist will again take a load sample each time it passes through the previously established points. Once this last movement is complete, the instructions will indicate the profile recording is complete.

    Updating Full Profile: In the event that the load on the batten is changed (items added or removed) you will likely incur a "Load too heavy" or "Load too light" error. To rectify this, you have two options: re-record the entire Profile (using the same process outlined before), or just update it.

    To update the Profile, you designate which hoist you wish to manage the Profile, then hit the Preset button. What this does is shift the entire previously recorded Profile by however much the weight on the batten has changed (based on its current position & load).

    "Snapshot" Profile: If a Full Profile has not yet been recorded on this hoist, you can use the update process detailed above to record a single-point Profile. Because only one point is recorded, the load above and below is assumed to be the same as the single-point. Once a full Profile is recorded, though this "feature" is unavailable.

    Notes: Although it instructs you to go to a limit, it doesn't actually care if you achieved a limit or not. This can be helpful when attempting to record a profile on a batten that has materials hung on it that would prevent full travel. If you travel beyond the recorded profile's extents, it assumes that the weight is the same as the last point it passed.

    As of hoist firmware v1.30, there is no way to erase a profile once one is recorded. Hoist firmware v1.4 is scheduled to include this functionality and Foundation v1.2 is supposed to incorporate it on the front end (QT+ v1.4 will probably have it as well).
