ArcSystem Fixtures do not Dim Out Of Box


After initial installation and power up of an ArcSystem fixture, that fixture will not dim and stays at full brightness.

Description/Explanation of Issue

ArcSystem fixtures are set at the factory to have a minimum level of 100%. This is intended to allow an EC to verify fixture operation without needing to configure it.


  1. For RDM fixtures, use Net3 Concert to set the minimum level of the fixture to a level lower than 100%.
  2. For ArcMesh fixtures, use the ArcMesh Commissioning Tool and software to assign the correct minimum level.
