Performing a Quick Setup
Quick Setup is used to set up your rack using a minimum amount of data to achieve a basic
configuration.
Note:
CAUTION:
You can begin a quick setup by navigating to [Setup]>Quick Setup>[Enter].
From this interface you can use the CEM3 interface to enter data in up to four fields to
quickly establish your rack configuration: Rack Number, First Circuit, Numbering, and
Dimmer Double (see below for field descriptions).
Once you have entered data in the desired fields, select [Go] and press [Enter] to save the
setup changes.
Rack Number
Enter a reference number between 1-999 to identify the rack. Default is 1.
First Circuit
Enter the desired number for the first circuit in the rack. If this is your first or only rack, this
number is typically 1. If this rack is one of many in your system, this number typically
continues the numbering sequence from the previous rack. Default is 1.
Prior to performing a Quick Setup, make sure that your rack DIP switch settings
are set appropriately for your rack type. See Setting Rack DIP Switches and
Termination, page 40 for more information.
Quick rack setup will overwrite some of the data in your rack. Only perform a quick
setup when you wish to reconfigure your system or are instructed to do so by ETC
Technical Services.
Numbering
Choose between “Straight” or “Balanced”. “Straight” results in circuit numbering that will
proceed sequentially straight through the entire rack. See Straight (rack numbering), page
16 for more information.
“Balanced” results in circuit numbering that will distribute the circuits evenly across the
different power phases so that neighboring circuits do not place an uneven load on any
phase. See Balanced (rack numbering), page 10 for more information.
Default for Sensor3 installed racks (SR3)is “Balanced”. Default for Sensor3 portable racks
(SP3) is “Straight.”
Dimmer Double
Choose between “Yes” and “No” to activate or deactivate dimmer doubling for the rack.
Default is “No” (see Dimmer Doubling (UL/ 120V 60 Hz systems only), page 11).

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:

10 CEM3 User Manual
Circuit
A circuit is a user assignable number, between 1 and 99999. the circuit is the reference
number for that dimmer in the rack. Circuit numbers must be unique per space; it is possible
to have multiple circuits of the same number, but they must be in different spaces.
Configuration
The rack configuration is a collection of all of the data stored about the rack and all of its
circuits. The configuration is stored automatically in the CEM3 whenever you make a
change (for example, changing a circuit from switched to dimmed).
The configuration of any rack is automatically stored on both the CEM3 module and the
CEM3 backplane. Therefore, you can remove a CEM3, replace it with a new, unconfigured
CEM3, and the configuration from the backplane will be loaded to the new CEM3.
You can save and load rack configurations by connecting a USB removable media device
to the USB port on the front of the module. Saving and loading are performed from the File
Operations menu (see File Operations, page 18).
Dimmer Doubling (UL/ 120V 60 Hz systems only)
ETC’s Dimmer Doubler™ technology allows you to double the number of controllable
circuits in your system without adding dimmer modules or running additional cable. The key
to this feature is the Dimmer Doubler two-fer.
The Dimmer Doubler two-fer is installed between a Sensor dimmer module and two ETC
Source Four 77 volt fixtures. It splits the output of a single dimmer into two, separately
controlled outputs.

Diagram of How Latch-Lock is Applied to a Circuit
Latch Lock is a control mode available to any dimmer circuit (see Control:, page 20). Similar
to switched mode, Latch-Lock features an additional safeguard so that circuits can not be
turned on or off as easily. The circuit only turns on when a defined control level range is
held for a specified amount of time, and only turns off when a different control level range
is held for another amount of time. Latch-lock is useful for avoiding accidental dowsing of
arc lamps during shows (often caused by running the Grandmaster down). By requiring a
level range and time, most master fades will not hover in a given range for long enough to
trigger on or off.
The level ranges and times can be edited on a per dimmer basis (see Dimmer Property
Definitions, page 19). On and Off level ranges may not overlap.
Lug
“Lug” refers to a physical position in the rack. Lugs are always numbered counting
downwards from the top of the rack, starting at “1.” Some modules may take up multiple lug
positions in the rack.
Panic
CEM3 offers a Panic capability that complies with UL 924 Panic functionality.
When a properly connected and enabled CEM3 has a panic “look” stored, when it receives
a signal over the panic circuit it will automatically play the recorded look.
Panic can be enabled when a maintained (normally open or normally closed) contact
closure is properly wired to the backplane (for more information, see the data termination
guide or installation guide that was supplied with the rack).
For information on how to configure Panic on your CEM3, see Setting Up Panic, page 35.
12 CEM3 User Manual
Patch
Patching governs the relationship between control input sources (DMX A, DMX B, and
sACN) and the control of circuits in the rack. This relationship can be edited to match the
needs of your control sources and rack constraints. For information on patching, see
Setting Up Patch, page 37.
Preset Functions
CEM3 supports a built-in preset control system allowing the recording and playback of
preset looks. Preset looks can be played back either from the CEM3 face panel or using
connected Echo preset stations. For more information on recording and playing back
presets see Recording and Playing Back Presets, page 32.
CEM3 allows the circuits within the rack to be divided up into spaces (performed in Circuit
Assignment, page 18) with 64 presets available per space. Each space can only have one
active preset at a time.
CEM3 includes default presets that include all circuits in the space. The default presets for
any space start with 100% and then cycle through 75%, 50%, 25%, 100% and so on.
Sensor3’s built-in EchoConnect power supply is limited to powering six racks or panels and
six stations. An additional wall mounted or rack mounted power supply can be added to a
system to support up to sixteen hosts and sixteen stations
CAUTION:
Preset activation propagates across the Net3 network. So if a given preset is activated for
Space 1, all CEM3s on the network will activate that preset for space 1.
Rig Check
In Sensor3 racks with Advanced Features (see Advanced Features (AF), page 10) you can
record a special preset called “Rig Check” which includes both circuit levels and the amount
of load (current) expected on each circuit.
Once recorded, the rig check can be played back, either from the CEM3 face panel or
remotely, and the CEM3 will post load high, load low, or no load messages based on how
the load of the circuit has changed since you recorded the rig check preset. These
messages will be available on the CEM3 display or on a connected console that monitors
AF feedback.
Recording, running, and clearing a rig check can be performed from the Test menu (See
“Test” on page 17.)
Do not activate “Station power” on more than one CEM3 on the same
EchoConnect bus. Doing so may cause undesirable station function.

Spaces
Spaces are logical divisions within a system (such as different rooms) that isolate station
control (preset and sequence control) to the defined group of controllable outputs in that
division. CEM3 supports separation of its controllable circuits into spaces.
Station Functions
Presets can be played back from preset stations in the system.
• Press a preset station button to activate a preset.
• Press it again to deactivate the preset.
• Stations can be configured with an “Off” button. This option is performed at the
station and should only be done by a qualified technician.
• The group of presets controlled by any station can be altered at the station. This
should only be done by a qualified technician.
For more information see the Echo Preset Station Installation Guide available from the ETC
web site.
Zones
A space can be broken down further into zones. You can assign zone control to a preset
station for direct control using that station’s buttons and fader knob. Multiple zones can exist
within a space and a single zone can control multiple outputs across multiple racks.
A circuit’s control zone is a dimmer property and is assigned by accessing the dimmer setup
menu (see “Arch Zone:” in Dimmer Property Definitions, page 19).
Each space can have up to 16 zones assigned (numbered 1-16).You can omit a circuit from
zone control by setting the Arch Zone value to zero.
Redundant Tracking (ESR and FDX racks only)
Redundant tracking provides extra security in the event of system failure, allowing a
secondary CEM3 control module to immediately take control of the rack.
Redundant tracking is available in ESR and FDX racks only.
For more information, see Redundant Tracking Systems, page 51.

Straight (rack numbering)
Straight rack numbering assigns consecutive dimmer numbering vertically, from top of the
rack to the bottom, regardless of phasing.
This table compares the circuit numbering of an SR3-6 filled with D20 modules when set to
straight or balanced numbering:
