Performing a Quick Setup

Quick Setup is used to set up your rack using a minimum amount of data to achieve a basic configuration.

N o t e :	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.
C A U T I O N :	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.

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.

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:

	Rack	SR3-6	SR3-6
		Straight Circuit	Balanced Circuit
	Phase	Numbering	Numbering
		1	1
	A	2	2
		3	7
		4	8
		5	3
	B	6	4
		7	9
		8	10
		9	5
	C	10	6
		11	11
		12	12

Racks can be set as balanced by Performing a Quick Setup, page 7.

10	CEM3 User Manual

Ci rcuit

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.

2	System Reference	11

Latch-Lock

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.

Relay Closes

Relay Opens

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

C A U T I O N :	Do not activate “Station power” on more than one CEM3 on the same
	EchoConnect bus. Doing so may cause undesirable station function.

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.)

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:

	Rack	SR3-6	SR3-6
		Straight Circuit	Balanced Circuit
	Phase	Numbering	Numbering
		1	1
	A	2	2
		3	7
		4	8
		5	3
	B	6	4
		7	9
		8	10
		9	5
	C	10	6
		11	11
		12	12

Racks can be set to straight through Performing a Quick Setup, page 7.
