10 CEM3 User Manual
Important Concepts
This section introduces you to some of the primary concepts and their functionality, which you
may encounter through your use of the CEM3 power control system. Topics are listed
alphabetically.
Advanced Features (AF)
Advanced Features (AF) allow you to receive feedback from your dimmer modules about
their current state, including the amount of current being drawn on each circuit, whether the
module is installed or not, and whether the circuit breaker on the module has tripped. This
feedback information is available both at the front panel of the rack and at remote devices
including ETC's Eos and Congo control systems, and other ACN capable devices.
Having Advanced Features also allows you to monitor circuit loads by recording and
running a rig check (see Rig Check, page 13 ).
In order to use AF you need AF capable modules (denoted by having AF in the module
name, for example D20AF or ED15AF), and also AF cards installed in the rack.
Balanced (rack numbering)
Balanced rack numbering alternates dimmer numbering across phases in groups of two
dimmers.
This table compares the circuit numbering of an SR3-6 filled with D20 modules when set to
straight or balanced numbering:
Racks can be set as balanced by Performing a Quick Setup, page 7 .
