Dimmer Operation
Operating Manual
HUB24 Series Dimmer
The user definable curves can be used for lamps whose light output is not linear, for
lamps with special requirements (eg. fluorescent tubes) or if any special curve is
required.
The user definable curves are created and edited on a PC (or Laptop) using Jands
Dimmer Utility software and downloaded to the dimmer. See appendix A for how to
use the Dimmer Utility software and see section 4.4 on how to download the curves
to the HUB24.
•
Select “2-1 Control Curve” on the menu.
•
Turn the encoder wheel to highlight a dimmer output and press SELECT.
•
Turn the encoder wheel to highlight one of the four control curves.
•
Press OK to apply the new curve to the dimmer output and exit.
•
Repeat for each dimmer output.

2-2 Current Limit
The HUB24 constantly monitors the supply current, in each phase, consumed by both
the dimmer and distribution outputs. If more than a preset limit is drawn from a
phase, all the dimmer outputs on that phase are dimmed down until the current drops
to near the preset limit.
•
Select “2-2 Current Limit” on the menu.
•
Turn the encoder wheel to highlight “32A” or “40A” or “50A” or
“63A” or “No limit”.
•
Press OK to save the new current limit and exit.

3 Test
3-1 Drive Output
Drive output allows testing of each dimmer output from the menu, with or without a
console present. A single output, all 5 outputs on a phase or all 15 outputs can
temporarily be faded from 0% to 100%. After testing, each dimmer output returns to
its previous level.
Note: The drive output menus do not timeout and return to the main screen.
Single Output
•
Select “3-1 Drive Output” on the menu.
•
Ensure “Ch 1 - Next” is highlighted and press SELECT.
•
The present drive level of the selected output will be displayed as a percentage.
Turn the encoder wheel to change this output level.
•
Press NEXT to control to the next output, the previous output will revert back to
its original level. Repeat the previous step for the new output.
Note: Pressing NEXT when driving Ch 15 will jump back to Ch 1.
•
Press CANCEL at any time to exit, all outputs revert back to original levels.
