Question: Seeing flickering in a rack. Could this be due to an airflow problem? Answer: Yes it can. The rack can get caught between system ok and airflow error. This can cause flicker. If all of the dimmers that are active in the rack always flicker out together, airflow could be a factor. If they change...

There are a number of issues that can appear as "flickering" in a Sensor dimmer rack. Airflow issues are a common reason that all dimmers in a rack might flicker together: Sensor Dimmer Rack Flickering Due to Airflow Issues DMX problems might cause all dimmers in all racks to flicker sporadically...

In non-dimmed applications, branch circuits are often installed with three circuits sharing a common neutral conductor, where each of the three circuits is on a different phase. This is known as a “multiwire” branch circuit arrangement. It is used to save costs because only four total conductors...

Verify that the Max Scale setting for each dimmer on the CEM+ is set to about 118. Verify that the Curve setting for each dimmer on the CEM+ is set to Mod Square. If this doesn’t work, try Sensor 2.0. Make sure to check the voltage readings with a True-RMS meter. NOTE: Any work (including metering...

Problem: Dimmer modules slide out about 1/2" during transport of the rack. Modules must be re-seated before each use. Solution: Install (2) 7053A3087 Module Retainers per door (i.e. 2 per SP24, 4 per SP48). This will help to hold the modules in place.

We often get asked about wire temperature ratings and how they relate to dimmer rack wiring and the allowable number of circuits in a conduit or wireway. While the ultimate authority on wire size, temperature ratings, and conduit fill is the project electrical engineer, and then the local inspector,...

If your relays are chattering or not firing in your Sensor, Sensor+ or Unison rack there may be a problem with the neutral wire on your signal distro card. Make sure that the neutral wire is present and connected on both ends. This problem can also cause ELV10 modules to not work correctly in test mode...

When equipment goes bad out in the field, it's often extremely helpful if the owner/end user can keep track of the circumstances of the failure. This is especially true when the problem is intermittent and might not occur when the technician is present. Service Technicians are exceptionally skillful...
