  • Minimum Levels in CEM+

    We have received a number of calls from customers wanting to set a minimum level on a Sensor dimmer using CEM+.  Quite often people are trying to meet a minimum lighting level requirement for walkway or overhead lighting to allow for safe movement within a facility during a performance.  Here is a way to do this on a dimmer by dimmer basis as outlined below:

    Use the browser or DimSTAT to enable Preheat and change the Minimum Scale from 6 to the desired voltage (start at about 20).  Also, you may wish to alter the Dynamic Preheat time depending upon application.  Dynamic Preheat is a modifier to Preheat that defines a time that the dimmer will go to zero output when its control channel is brought to zero after being at a higher level.  After completing that off time it will then fade back up to the Preheat level.  It allows a true blackout to happen in the facility for a few moments.
