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.

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.

Determines the control mode of the dimmer. Possible settings are
Dimmable, Smoothing, Off, Always-On, Switched, Latch Lock,
TPAuto, and TPDMX (see individual definitions below).
Dimmable - Circuit dims according to curve within the minimum and
maximum scaled voltages.
Smoothing - The dimmer adds a deliberately slow reaction time to
changes in control level to “smooth out” dimming performance with
loads that react quickly such as LEDs or low wattage lamps.
Off - Circuit ignores incoming levels and will not turn on even with
local overrides.
Always-On - Circuit ignores incoming levels and will not turn off even
with local overrides.
Switched - Circuit operates as a relay with output unregulated AC
voltage when the control level is above the control threshold level.
Latch-Lock - similar to switched mode, Latch-Lock functions as a
relay but features an additional safeguard so that circuits can not be
turned on or off so easily. See Latch-Lock, page 12.
TPAuto - For ThruPower modules. The control input to the circuit
dims the circuit if it is between 0 and 99%. When the output is set to
100%, the relay of the ThruPower module closes.
TPDMX - For ThruPower modules. Two addresses (or three
addresses when combined with 16-bit mode) control the dimmer and
the relay of the ThruPower module. When the second address is
below 50%, the first address acts as a relay control, turning the relay
on at the threshold value. When the second address is above 50%,
the first address acts as a dimmer in the normal manner, dimming the
output.
The current operating curve for the dimmer. Options are: Mod-
Square, Square, Linear, Mod-Linear, Sensor 2.0, and Custom 1-5.
For more information curves see Dimmer Curves, page 23.
In switched mode the threshold value defines the control
percentage at which the output turns on. In dimmed mode, the
threshold defines the level at which preheat is applied. See
Dimmer Output Diagram, page 30 for an illustration of how
threshold works with other dimmer properties.
Latch-Lock only - The control level range (as percentage) that
causes the “On Time” to start counting down. Ranges available in
10% increments. Default is 41-50%.
See Latch-Lock, page 12.
Latch-Lock only - The control level range (as percentage) that
causes the “Off Time” to start counting down. Ranges available in

The scale load setting allows hyper-accurate regulation of the
voltage of the dimmer output. The scale load allows the CEM3
dimming engine to compensate for power losses occurring in the
choke of the dimmer. The scale load is calculated as the load on
the channel divided by the channel’s capacity (in Amperes) and is
expressed as a percentage. For example, a 5A load on a 20A
channel would have a scale load of 25% (5A / 20A x 100% =
25%).

Dimmer curves determine how dimmers set voltage output in response to control signal
input. To accommodate designer preferences and load response variations, Sensor3 offers
several dimmer curves which can be applied to individual dimmers (see Curve:, page 20).
The available curves in CEM3 are as follows.
Linear
The linear curve matches the control input percentage to Root Mean Squared (RMS)
voltage output. Each percent increase in control level increases dimmer voltage output by

A modified linear curve reduces the voltage change at low control levels for better

Square Law (Square)
At low control levels, much of a traditional incandescent fixture’s light output is in the
invisible infrared spectrum. This results in poor visible response to low control levels. A
square law curve applies a multiple derived from the square root of the control level (with
full output equal to 1.00) to increase voltage response at low control levels to compensate
for the infrared loss.

Recording and Playing Back Presets
CEM3 has the ability to record and play back snapshot looks called “Presets.”
Presets can be recalled from the CEM3 or from any compatible Echo preset stations. For
information on wiring preset stations, see the Sensor3 CEM3 Data Terminations Guide and
the Echo Preset Station Installation Guide.
Up to 64 presets can be recorded for each space, numbered from 1-64. Only one preset
can be active at a time in the same space.
Preset Menu
Presets are recorded by taking a snapshot of the current levels for all circuits assigned to
the space that are set to be included in presets (see Allow in Preset:, page 21). If a circuit
is not set to be included in presets, any level it is currently using will be withheld from the
record action.
To record or play back a preset:
Step 1: Set the desired output levels for any dimmers in your rack using any method
(methods include: “Set Levels” feature on CEM3, DMX device, or sACN device).
Step 2: Using the CEM3 face panel, navigate to [Test]>Presets. The “Select Space”
screen will appear (if multiple spaces exist).
Step 3: Select the space you wish to record the preset for (if applicable) and then select
OK. The Preset screen will open.
Step 4: Select the preset (1-64) that you wish to record for the space. This will then give
you access to the preset menu. From this menu you can now perform the
following actions:
• [Activate/Deactivate] - [Enter] toggles the preset between on and off.
• [Snapshot/Record] - [Enter] records the current levels for the space to the
selected preset.
• Fade Time: set the desired time (in seconds) for the preset to fade in and out
when activated/deactivated. Range is from 0-360 seconds. Default is 2
seconds.
Step 5: Release the output levels ([Test]>Release Set Levels) or turn off the control
source data.

removing dimmer or control modules for service, de-energize main feed to
dimmer rack and follow appropriate Lockout/Tagout procedures as
described in NFPA Standard 70E. It is important to note that electrical
equipment such as dimmer racks can present an arc flash safety hazard if
improperly serviced. This is due to available large short circuit currents on
the feeders of the equipment. Any work on energized equipment must
comply with OSHA Electrical Safe Working Practices.
• “NC” - Use this setting if the emergency contact closure is a “Normally
Closed” contact closure.
• “Disabled” - This setting disables the Panic function for this CEM3 control
module.
• “NO” - Use this setting if the emergency contact closure is a “Normally Open”
contact closure.
Step 1: Set the desired output levels for any dimmers in your rack using any method
(methods include: Set Levels, DMX device, or sACN device).
Step 2: Using the CEM3 face panel, navigate to [Setup]>Panic>Record Panic
Look>[Enter]. If a panic look was already recorded, a confirmation screen will
appear asking you if you wish to overwrite the Panic look.
• Select “Yes/Save” to overwrite the old Panic Look. The look will be saved.
• Select “No/Cancel” to abort the record. The look will be aborted.
Once a Panic look is recorded, when the emergency contact closure is triggered the Panic
look will be activated. When the contact closure is returned to its normal state, the Panic
look will be deactivated.
Other Panic Settings
From the Panic Setup menu ([Setup]>Panic) you have access to the following settings that
will affect the manner of a Panic look activation:
• In Delay (sec) - This setting determines the length of time (in seconds) for the Panic

Setting Up Patch
Patch governs the relationship between control sources (DMX A, DMX B, and sACN) and
the rack’s circuits and is editable from the CEM3 face panel. Typically, repatching is used
in portable rack situations where the dimmer rack must adapt to different control sources
and lighting systems. For permanent rack installs, altering your patch is rarely needed.
Racks with only one assigned space can have their patch edited through one of two
methods: Manual or Automatic. Racks with multiple assigned spaces can only be edited
manually. For racks edited using an automatic method, circuits will be numbered
sequentially from the specified starting address following the designated “Straight” or
“Balanced” setting in Quick Setup.
Any circuit set to a patch of “0” will render that circuit uncontrollable from the data source
specified.
Automatic Patch
Note:
When you chose an automatic patching method the entire rack will be patched sequentially
based on the criteria of the chosen option in Quick Setup. Only racks with one assigned
space can use these methods.
If dimmer doubling is enabled, you will see additional fields for addressing dimmer doubled
circuits.
There are three options offered for automatic patching: Simple, Split, and Independent.
Simple
This patching method specifies the same starting circuit for all three data ports (DMX A,
DMX B, and sACN) at once. Enter the starting number for the patch. Universe size is 512
dimmers (256 if dimmer doubling is enabled). If the patch count exceeds 512, the patch will
“wrap” and start numbering again at 1 (257 for dimmer doubling).
Split
This patching method should be used when a DMX universe will end part way through the
rack’s patch. Enter the starting number for the patch. If the patch sequence exceeds 512
(256 if dimmer doubling is enabled) DMX A will patch the rest of the circuits to “0” and DMX
B will restart the patch numbers at 1 for those remaining circuits.
Independent
This method allows you to specify different starting numbers for each data port in the patch
(DMX A, DMX B, and sACN). Select a data port and assign the desired starting address for
the rack. If the rack count then exceeds 512 (for DMX ports) the remainder of circuits in the
rack will be patched to zero for that DMX port.
Module density can affect patching. Prior to patching, make sure you set up the
module type in [Setup]>Circuit Assignment.
To set an automatic patching method:
Step 1: Navigate to [Setup]>Patching>Automatic: <choose method>.
Step 2: Enter or scroll to the desired starting channel number using the keypad. For
Independent Mode, repeat for the other data ports.
Step 3: Press [Enter] and confirm to save the changes.
3 Common Tasks 37
Manual Patch
Manual patching allows you to alter the patch on a circuit-by-circuit basis. There are two
independent options for manual patch editing: DMX and sACN. Both can be set individually
for your needs.
To edit the patch manually:
Step 1: Navigate to [Setup]>[Patching]>[Edit DMX / sACN Patch]
Step 2: Press [Enter]. The Select Space screen will appear (if multiple spaces exist).
Step 3: Select the desired space (if applicable) and then select OK. The Patch Table will
open.
Step 4: Use the scroll wheel or keypad to select the DMX port (A or B) or sACN universe
and channel for the desired circuit.
Step 5: Press [Enter]. The field will become editable.
Step 6: Scroll to or enter the desired channel from the keypad.
Step 7: Press [Enter].
Step 8: Repeat steps 4-7 for all desired circuits in the space.
Step 9: Press [Back] when done. A confirmation dialog will open.
Step 10: Select [Yes/Save] to save the changes. Press [No/Cancel] to abort. Press
[Continue Editing] to edit further circuits.
Step 11: Repeat steps 2-10 for any additional spaces.
Set Data Loss Behavior
You can designate the rack’s reaction to a loss of data from any of the three data ports
(DMX A, DMX B, or sACN). For each of the ports you can select one of the following
behaviors:
• Crossfade - On loss of data, the look will transition to a specified internal preset.
• Wait & Fade - On loss of data, the rack will wait for a specified amount of time and
then fade to black over another specified time.
• Hold Last Look - On loss of data, no transition occurs. The levels will stay at the
last known look until data is restored to the port. Resetting the processor will
release the levels.
To set the data loss behavior for any port:
Step 1: Navigate to [Setup]>Rack>Data Loss Behavior. The Data Loss Behavior
screen will be displayed.
Step 2: Use the scroll wheel to highlight the desired port behavior (DMX A, DMX B, or
sACN) and press [Enter]. The behavior will be highlighted.
Step 3: Use the scroll wheel to select the desired behavior (see above) and press
[Enter].
a: Select “Fade Time” (if applicable) and set the desired time (range is 0-360
seconds).
b: Select “Wait Time” (if applicable) and set the desired time (range is 0-360
seconds).
c: Select “Preset Space” (Crossfade only) and select the space that contains
38 CEM3 User Manual
the desired crossfade preset.
d: Select “Preset Number” (Crossfade only) and select the desired preset (1-
64) for the crossfade.
Step 4: Repeat for the remaining data ports if desired.
Setting Up CEM3 on the Network
Network setup allows editing of the CEM3 network properties to establish the rack’s IP,
address. Three options for setting network characteristics are available: Link Local, DHCP,
and custom. The default is DHCP.
You can access this menu by navigating to [Setup]>Network>[Enter]. After the desired
method is set, a confirmation window will open asking you to confirm or abort the changes.
Link Local
Choose Link Local if you work in a touring system where equipment changes frequently.
Link Local automatically assigns an IP address, in a special rang, with the IP being
randomly generated.
DHCP
Choose DHCP if your system includes a DHCP server (for example, an Eos console).
This setting will attempt to acquire an IP address from a DHCP server. If the request fails,
CEM3 will acquire its address through Link-Local (see above) for this boot cycle only. If
rebooted, the rack will attempt a DHCP request again.
Custom
With this method you can directly set the IP address, Subnet, and Gateway manually using
the keypad. ETC’s convention for IP address is to use 10.101.xxx.yy (“x” varies by ETC
product line, “y” increments for products of the same type).
Network Setup for Redundant Tracking Racks
The Redundant Tracking option is only available for ESR and FDX systems.
In a redundant tracking system, each processor has a separate network connection to
which a separate IP address may be assigned. When working in a redundant tracking
system CEM3 will prompt to select which processor (A or B) you wish to alter the IP settings
for.
Working with an FTP Server
CEM3 supports automatic or manual backup of the dimmer rack configuration to a server
on an Ethernet network using the FTP (File Transfer Protocol) standard.
Before you can save to an FTP server you must first set one up from the CEM3 face panel.
To set up an FTP server from CEM3:
Step 1: Navigate to [Setup]>File Operations>Set Up Server.
Step 2: Press enter to change enable to “yes”.
Step 3: Specify the IP address of the server.
Step 4: Specify the file name in “File”.
Step 5: Set AutoSave. When set to “Yes,” every time a change is applied to the
3 Common Tasks 39
configuration it will be saved to the server. “No” means you will have to manually
save.
To manually save a configuration to an FTP server, navigate to [Setup]>File
Operations>Save to Server.You can edit the file name prior to saving using the scroll
wheel and the keypad to enter letters.
To load a configuration from an FTP server, navigate to [Setup]>File Operations>Load
from Server and choose the desired file from the list that appears (CEM3 configuration file
names end in “.etc”).
To upgrade CEM3 software from an FTP server, navigate to [Setup]>File
Operations>Load from Server and choose the desired file from the list that appears
(CEM3 software file names end in “.bld”).
Setting Rack DIP Switches and Termination
WARNING:
On the CEM3 backplane, located in the rack behind the CEM3 control module, there is a
small bank of 8 DIP switches. The setting of these switches should be set to match the
specific size, features, and desired behavior of your dimmer rack.
Generally, you should not need to alter these settings as they should have been set when
your system was commissioned by an ETC technician. However in the event that you must
replace your CEM3 control module or backplane, you will need to ensure these settings
match the previous controller.
Use this section to determine the required settings for your dimmer rack. There is also a
label on the underside of the CEM3 that explains the function of each switch.
When setting the DIP switches, you may also need to check the DMX A and DMX B
termination settings for the rack. Reference the backplane label to determine the
appropriate position of the termination switch.
To avoid the possibility of electric shock, power must be turned OFF when
you perform this procedure. Before removing dimmer or control modules,
de-energize main feed to dimmer rack and follow appropriate Lockout/
Tagout procedures as described in NFPA Standard 70E. It is important to
note that electrical equipment such as dimmer racks can present an arc
flash safety hazard if improperly serviced. This is due to available large
short circuit currents on the feeders of the equipment. Any work on
energized equipment must comply with OSHA Electrical Safe Working
Practices.
DIPswitch settings
The eight DIP switches relate to behavior, features, or the module size of the rack. In the
descriptions below, switches set in the up position are “On” and switches set in the down
position are “Off”.
DIP 1 - “DBM”
This switch disables the backplane memory so that the configuration is not stored on the
rack itself. Default is “OFF”. If set to “ON”, a Rack Memory Error will be displayed on the
CEM3.
40 CEM3 User Manual
DIP 2 - “AF”
This switch should be set to “On” if your rack has Advanced Features (AF - see Advanced
Features (AF), page 10).
DIP 3 - “HSR 240V”
This switch should be set to “On” if your rack is an HSR rack intended for use with 240VAC
power feeds.
DIP 4 - “ESR 230V”
This switch should be set to “On” if your rack is an ESR rack intended for use with 230VAC
power feeds.
Note:
For JSR dimmer racks, intended for use with 100VAC power feeds, both DIP 3
and DIP 4 should be set to “On”.
DIP 5 - “ND”
This switch should be set to “On” if your rack includes a neutral disconnect.
DIPs 6-8
These DIP switches are used together to determine the number of module slots in your
rack. Refer to the table below to find the desired settings for your rack size.
Rack size 6 7 8
6 module slots Off On On
12 module slots Off On Off
24 module slots Off Off On
36 module slots On Off Off

Termination Switches
DMX signal requires a a signal termination at the end of a data run. If your rack is the last
device on the data run for either DMX A or DMX B, set the termination switch for the
appropriate run to “ON”. The switches are labeled “B” or “A” on the backplane label.
If the rack is not the last device on either data run, leave these set to “Off”.

Rack Maintenance and Cleaning
Proper air flow is necessary for your Sensor3 rack to function properly and consistently.
Perform the following procedures regularly to keep dust and foreign debris from impeding
the proper function of your rack.
Cleaning Rack Air Filters
Clean the air filter in the Sensor3 rack door a minimum of every six months, more often if
your system operates in a dusty environment. This will also provide an opportunity to
inspect the dimmer module air vents and clean them if necessary (see Vacuuming Dimmer
Modules, page 43).
To clean your rack air filter:
Step 1: Open the dimmer rack door. The air filter is mounted on the inside of the door,
held in by a metal lip at the bottom of the door frame.
Note:
Sensor3 48-module racks have two filters, one stacked on top of the other with a
retention bar in the middle of the rack. Remove the top filter screen before
removing the bottom one.
Step 2: Slide the filter upwards approximately 1/2 inch (1.25cm) until the base of the filter
clears the top of the metal lip.
Step 3: Pull the bottom of the air filter out and away from the door far enough to clear the
retaining lip and slide the filter downwards and out of the door frame.
Step 4: In an area away from your dimmer rack and other dust-sensitive equipment,
remove all dust or debris from the filter using either compressed air or a vacuum.
CAUTION:
42 CEM3 User Manual
You may rinse the filter under cold tap water, but it must be completely dry before
you reinstall it.
Do not use soap or other chemical cleaners to clean the filter. They may damage
the filter screen.
Step 5: Slide the top of the filter up into the slot at the top of the door until the base clears

Step 6: Ease the filter back into the door frame and carefully let it drop back into place.
Note:
For Sensor3 48-module racks, install the bottom filter first. The top filter rests on
the top edge of the bottom filter.
Vacuuming Dimmer Modules
As with cleaning the air filters, you should inspect the dimmer module air vents and SCR
power cube inlets every six months and clean if necessary, more often if your system
operates in a dusty environment.
WARNING:
To vacuum the dimmer module air inlets:
Step 1: Open the rack door and inspect the air vents on the CEM3 and the air vents and

Redundant tracking in an FDX3000 Rack
Redundant Tracking Systems
CEM3 features the ability to support dual redundant controllers in ETC's ESR24, ESR36
and ESR48 rack types, as well as in the FDX3000 rack.
Redundant controllers provide extra security in the event of system failure, allowing a
secondary processor to immediately take control of the rack.
C Redundant Tracking Systems 51
Redundant Tracking Switch
The redundant tracking switch determines which controller runs the output to the dimmers.
It has three positions.
• When the switch is set to A (upper position), the upper controller has control of the
dimmers.
• When the switch is set to B (lower position), the lower controller has control of the
dimmers.
• When the switch is set to Auto (center position), control is automatically allocated
based on the health of the system (see below for details).
Automatic Control
Processor A
Processor B
Typically, in a redundant tracking system, the switch should be left in the auto position.
When the switch is set to auto, the A processor will have control by default. Control will
switch to B when any of the following events occur.
Loss of network
If network connectivity is lost to one processor but not the other, control will switch to the
one which still has network connectivity.
Loss of DMX
If DMX is lost by one processor but not the other, control will switch to the one still able to
receive DMX (note that the DMX data line is interconnected between both, so this would
only occur in the event of the failure of a DMX transceiver on the processor itself).
Power errors
If one processor experiences power errors but the other does not, control will switch to the
one that does not. Again, note that the same power is connected to both processors so this
would only occur in the event of an internal failure in the processor.
Total processor loss
If communication is completely lost to one processor but not the other, then control will
switch to the processor which is still available.
Display Status
When tracking is active and the A processor is in control, the displays will show as follows:
Rack 1 - CEM3 Rack
System OK
DMXA: 1 DMXB: Off
sACN: 2/1
[Info]
CEM3 Control
Backup Ready
When control switches to the B processor (either by automatic failover or manual control
using the switch), the displays change to the following:
52 CEM3 User Manual
Rack 1 - CEM3 Rack
CEM3 Control
Backup Active
Processor A
Processor B
System OK
DMXA: 1 DMXB: Off
sACN: 2/1
[Info]
The switchover from A to B for dimming happens instantaneously, so that control of lights
is not lost. However, the switchover of the user interface has built in hysteresis to eliminate
bounce in certain circumstances (for example, when DMX is lost, both processors may not
see and account for the DMX loss at exactly the same time). For this reason it may
sometimes appear to take a long time for the user interface of the backup unit to start up;
however, bear in mind that dimming control always transfers near-instantaneously,
however some hysteresis is required for the startup of the user interface.
Configuration Management in Redundant Tracking Systems
In a tracking CEM3 system the two processors automatically communicate and
synchronize their configurations though the backplane - no external Ethernet network is
needed for the two processors to synchronize data.
Once you make a configuration change on one processor, that change is automatically
transferred to the second processor.
When the system boots up, it is assumed that the A processor has the most recent
configuration, so the configuration will be automatically transferred from A to B if B has a
different configuration.
Firmware Upgrades in Redundant Tracking Systems
When you upgrade firmware in a redundant system (either via the network or using a USB
key), the firmware upgrade is automatically transferred to both processors. Once the
firmware is transferred the upgrade will occur on both processors simultaneously.
Therefore it is not necessary to update both processors independently in a rack.

FDX 3000 Dimmer Racks
CEM3 may be used as a control module in ETC's FDX3000 dimming system, providing
networking facilities, dual redundant control modules, and precision 16-bit dimming. This
appendix details information needed to work with CEM3 in an FDX3000 system, as well as
outlining the hardware of your FDX3000 rack.
Hardware
Front Panel
The FDX3000 carrier contains two CEM3 modules in a dual redundant configuration.
PSU Indicators
The PSU indicators show the status of the two internal power supplies which supply the
15VDC required by FDX dimmer modules.
The two indicators should be lit at all times. If either is not lit, this could indicate a failure of
the internal power supply. If you see this condition, contact ETC Technical Services (see
page 3).
Redundant Tracking Switch
The redundant tracking switch allows you to test the ability to switch from the upper (A)
processor to the lower (B) processor. If it is set to the (A) or (B) position, the A or B
processor will preferentially have control. In normal operation, the switch should be set to
the center “Auto” position. This will ensure that A has control unless communication is lost
to A, or certain hardware failures occur on A but not B (for example if A does not see DMX
but B does).

Option Connector
Dimmer Outputs
The dimmer outputs connect from the FDX3000 processor to the dimmer module trays.
They should generally be pre-configured from the factory. They are grouped in blocks of 12
dimmers, from A(1-12) through H(85-96).
Feedback
The feedback connections allow the FDX3000 to determine the status of voltage and
current for modules that support sensing. Again the two feedback connections should be
made from the factory.
15VDC
The 15VDC connection provides 15V power to the FDX dimmer modules.
Option Connector
The option connector allows field connection of the rack options such as panic (see page
35), stations (see page 15), and a remote beacon. For information on these connections,
see the termination markings on the rear of the FDX3000 carrier.
DMX Connections
The FDX3000 processor features DMX In and Thru connections on two industry-standard
5 pin XLR connectors. The two DMX ports, A and B, are fed to both of the redundant
processors.
Ethernet Connections
Two Ethernet connections are provided using Neutrik Ethercon connectors, which may be
either connected to a neutrik ethercon jack or a standard RJ45 connector. “Net A” connects
to the A (upper) CEM3, and “Net B” connects to the lower. The CEM3s feature an internal
switch allowing use of the rear and front panel Ethernet connections at the same time.
Power Input
The power input connector is a three phase supply, fed from the supply in the rack. The
FDX3000 processor will function regardless of any phase loss; as long as at least one
phase is still active the processor will still dim any dimmers which still have power.
Fuses
The power input has three panel-mount fuse holders to protect against internal failure. The
56 CEM3 User Manual
fuses should only be replaced with the same type, 2.5A 20mm.
Regulatory Information
64 16 8 4 2 132
The FDX3000 rack is certified to the following CE standards:
Safety: EN61439-1 (Low voltage Switchgear and Controlgear assemblies)
Electromagnetic Immunity: EN61547 (EMC Immunity for Lighting Systems)
Initial Setup
Module Count
The FDX3000 controller supports between 1 and 96 dimmers. The number of dimmers is
configured using DIP switches on the backplane of the controller.
To configure or alter the number of modules configured in your FDX system:
Step 1: Turn off power to the rack.
Step 2: Remove the two CEM3 modules from the FDX3000 carrier.
Step 3: Set the DIP switches in binary to the number of modules in your rack. The DIP
switches are counted from left to right as follows:
• Up indicates the DIP switch is on. So, for example to set the rack up for 96
modules, set DIP switches 32 and 64.
Step 4: Reinstall the CEM3 modules.
Step 5: Power up the rack.
Module Types
The following module types are supported in FDX:
• Blank - Used where a blank plate is fitted; gives no control and no feedback
• NoV-Nol - A dimmer module with no current or voltage feedback.
• V-Nol - A dimmer module with voltage feedback but no current feedback.
• NoV-I - A dimmer module with current feedback but no voltage feedback.
• V-I - A dimmer module with voltage and current feedback.

Both “Breaker Trip” and “No Load” messages
may be produced and the roasting short
protecting feature will be enabled.
To configure the module type see Dimmer Property Definitions, page 19.
Roasting Short Protection
FDX3000 features a unique method for providing additional safety in the event of a roasting
short situation. A roasting short can occur when a dimmer is at a low level and driven into
a short circuit load with a long cable.
Because the dimmer is at a low level, the roasting short does not draw enough current to
trip the circuit breaker, however it is still a dangerous condition as currents can flow at a
high enough amperage to cause heat or, in extreme circumstances, fire.
The FDX3000 rack has the capability to detect this condition. When it is detected with a
module set to V/I mode the dimmer is automatically driven to full, allowing the high current
of the short circuit to trip the circuit breaker.
This facility is automatically enabled on any modules set to V/I mode.
