Sensor CEM Test Switch

Question:

Why are all of my lights stuck on at my Sensor rack and the screen (if the processor is a version with a screen) is blank?

What is the Sensor test switch, and what does it do?

Answer:

Every generation of Sensor has a test switch located on the CEM processor's circuit board. Activating the test switch will bypass all controls of the rack and place 5v on control lines to every dimmer module in the rack.  This should turn every circuit to full and you must flip it back off to resume control.
