C21/EC21 Series Dimmer Rack
Definition of Terms
This manual uses the following terms throughout:
channel
circuit
circuit ID
crossfade
cue
A device controlling a dimmer or group of dimmers. Historically, there is a physical
controller (such as a slider) for each channel. On most current control systems,
channels are numbers accessed by a numeric keypad. Each channel can control
multiple dimmers.
A connection device and wiring for powering a lighting fixture from a dimmer.
A unique four-digit numeric identity which you can assign to each dimmer. The
circuit ID may be the same as the dimmer number, or may be a number used to
indicate circuit location, phase, channel number, etc. This feature is useful for
system wide control functions.
A fade that contains both an up-fade and a down-fade, or any fade where the
levels of one cue are replaced by the levels of another cue.
The process of recalling a preset from its memory location and putting the result on
stage.
Preset, Memory, and cue are often used interchangeably.
curve
dimmer
default
A device controlling power to a lighting fixture. Two lights on the same dimmer
cannot be separately controlled.
The original factory settings.
DMX512
An ANSI communications protocol standard that describes a method of digital data
transmission between controllers, lighting equipment and accessories.
Ethernet
A high-speed network based protocol used to transmit data from a lighting
controller to a dimmer rack using a single Ethernet cable.
fade
fade time
level
Outlook
A gradual change in stage levels from one set of intensities (“look”) to another.
The time it takes for dimmer levels to go from their current levels to the levels in the
selected preset, or DMX value. Each preset has its own fade time.
A numerical value used to express the “brightness” of the load on a dimmer.
Usually shown as %.
A digital architectural control system for use with C21/EC21 dimmer racks.
patch
Historically, the process of physically connecting circuits to dimmers. Now usually
refers to electronic assignment of dimmers to channels.
phase
The three phases of the mains supply to which the dimmers are connected are
identified as Line 1, Line 2, Line 3 in 230v markets and as phase A, phase B, and
phase C in 120v markets.
power module
Operations Manual
The relationship between a control level and the actual dimmer output.
A chassis containing one, two or four dimmer or contactors. This is sometimes
referred to as a “dimmer”. However, each C21/EC21 power module can have
multiple dimmers or contactors in it, so this manual distinguishes between dimmers
(individual power control circuits) and power modules (a collection of one or more
power control circuits).
Page ii
preset
Preset fade time
profile
rack number
room
A pre-defined setup of intensities for a set of channels, stored in memory for later
replay. For Outlook applications, the C21/EC21 series dimmer rack processor
module stores 8 programmable presets per room for up to 16 rooms. For SWC
applications, the processor module stores 128 programmable presets. Preset 0
(ZERO) is always a blackout.
See “Fade Time”.
The relationship between a control level and the actual dimmer output. Also known
as ‘dimmer law‘ or ‘curve’.
A number used to uniquely identify each dimmer rack in a multiple rack system.
Rack numbers are set from the front panel of the rack processor module, and are
usually set by the installation engineer.
An area separately defined for purposes of architectural lighting control (e.g.,
Outlook control stations). This is usually a room in the traditional sense (an indoor
enclosed area) or a portion of a room that can be partitioned off. Each room may
be separately and simultaneously controlled by the system.
RPH
Rack Processor Housing
RPM
Rack Processor Module
SSR
(Solid State relay) A power control device used in Strand dimmers that contains
two silicon control rectifiers (SCRs), control circuitry, and optical isolation circuitry.
SWC
(System Wide Control) A method of programming and controlling more than one
dimmer rack simultaneously. A hand held controller lets you program and recall
128 presets, and control individual dimmers. 8 and 16 channel pushbutton
stations, and an A/V interface let you recall and 8 or 16 of the 128 presets at each
station. Please contact Strand Lighting or see the System Wide Control Data
Sheet or System Wide Control User’s Manual for details on how SWC works.
Technical Assistance
C21/EC21 racks and dimmers require a minimum of maintenance and servicing.
For operation or technical assistance, please contact Strand Lighting or the local
Authorized Service Center serving your area. (www.strandlighting.com)

C21/EC21 Series Dimmer Rack
Rack Components
The C21/EC21 dimmer rack is a listed, free standing, factory assembly of welded
steel and aluminum construction finished in a fine textured, scratch resistant
coating.
Each C21/EC21 dimmer rack consists of a rack processor housing (RPH) with one
or two rack processor modules (RPM), a fan module, and up to 24, 36 or 48
dimmer modules. The dimmer connectors at the back of the rack provide for load
wire connection. Main bus bars are provided for line wire connections. An earth
ground lug is provided in the rack. The dimmer connectors in the rack are
polarized to prevent dimmer modules being plugged into the different ampacity
slots. The dimmer racks can be individually fed or bused together using an
optional busing kit.
Large dimmer racks have provision for up to 48 dimmer modules. Mid-range
dimmer racks have provision for up to 36 dimmer modules. Small dimmer racks
have provisions for up to 24 dimmer modules. Dimmer modules contain one, two
or four dimmers, and dimmer module types can be mixed within a rack in various
combinations.

Dimmer Modules The power modules are the high power switching section of the C21/EC21
dimming system. The power block in this module is the interface between the high
power AC and low power control. It is driven by low level signals (5mA, 3-24V) and
switches high level signals (up to 100A, 120/240VAC). High specification filtering,
SCR dimming, contactor non-dims, Sinewave dimming, and load status reporting
electronics are available as options. Dimmers can be mixed in any combination in
a rack. This lets you use the exact dimmer type needed for each circuit.
Quad dimming modules are also available in custom racks.
Power modules are constructed from aluminum, folded to form three sides of the
dimmer and to support the dimmer connector and heatsink. The fourth side of the
dimmer is formed by the heatsink. The top and bottom of the dimmer are open for
cooling.
A sturdy handle is provided below the circuit breakers.
An optional mechanical locking bar on the dimmer tray secures the dimmers in the
rack.

Reporting Dimmer Most C21/EC21 dimmer modules are available in load status reporting versions.
Modules Load status reporting versions of dimmers can be mixed in any combination with
standard dimmers in C21/EC21 racks. These dimmers report many dimmer status
items back to the processor. The information can be accessed through various
menu items. The processor can then display a wide range of faults and diagnostic
data.
Each Reporting dimmer module contains a temperature sensor which will shut it
down if it overheats. Anything causing overheating in the rack will cause a gradual
shutdown as each Reporting dimmer module overheats.
Page 11
C21/EC21 Series Dimmer Rack
Fan Module The dimmer racks are cooled by a set of three low noise variable speed fans in a
fan module at the bottom of the rack. The cooling system is designed to let the rack
continue functioning if any one of the three fans fail. Cooling air is pushed up
through the dimmer stack and exhausted through venting at the top of the rack.
These fans are for dimmer cooling only, and can be set to fixed or variable speeds.
The fixed speed fan setting is for situations where changes in ambient noise are a
problem. With this setting, the fans are always ON when the dimmer rack is in
operation.
The variable speed fan setting minimizes noise and maximizes fan life. With this
setting, the fan speed is adjusted so that fans reach full when 24 dimmers are at
full, or equivalent (e.g., 48 dimmers at 50%). Increases in fan speed take 1 minute
with this setting, while decreases in fan speed take 5 minutes. Fans are turned
OFF when no dimmers are in use.

Rack Processor Housing Each C21/EC21 dimmer rack contains a rack processor housing (RPH) with all of
the control electronics for the rack. This RPH contains the processor module(s)
(RPM), control station power supplies, and control interconnection card (CIC) for
the rack, and is shipped separately from the rack to minimize the possibility of
damage.
This chassis can be equipped with one or two processor modules. The second
processor module acts as a backup. The configuration data from either processor
can be transferred into the other processor. The currently inactive processor
always tracks the currently active processor.

Rack Processor Module
Each C21/EC21 rack contains one or two rack processor modules (RPM). Each
processor module has a backlit LCD display, a 7 key keypad, and 6 LEDs to report
processor module and dimmer status and allow setup and control at the rack. In
normal operation, this display normally shows the rack name and the OK message.
If there are any rack or dimmer events reported, the display will show error
messages.
Pressing the < or > keys will takes you into a series of setup menus to view and set
up the more frequently used C21/EC21 features. See Section 3, Processor Module
Programming for details on accessing these functions.
All programmed data is held in battery maintained RAM for up to 6 months without
power.
Figure 5 – Rack Processor Module
Power Supplies
Control Interconnection
Card (CIC)
Each C21/EC21 rack can have up to three power supplies, depending on the
accessories provided. These power supplies are mounted on the rack processor
housing.
The electronics chassis also contains the control interconnection card (CIC). This
is where the contractor terminates all control wiring for the rack. All control terminal
strips are 2-part plug-in strips so that the electronics chassis can be easily
removed from the rack.
Processor Configuration Once you have applied power you need to make sure that the system is working
correctly and the processor modules are set properly for the installation. This step
checks for any problems due to shipping or installation.
Startup When the rack is switched ON, a number of self-tests are run. The system displays
the rack name.

Section 2 - Operational Features
Rack Configuration
The following configuration items are usually programmed during commissioning,
but can also be reprogrammed by the user.
Rack name.
Panic selection and configuration
Maximum output voltage (per dimmer): 20-250 volts (e.g. set to 105V for
extended lamp life).
Minimum level (per dimmer): 0% - 100% (e.g. set to 10% for aisle lights or
large lamp preheat).
Room and channel Patching (for applications using Outlook)
Each dimmer can be patched to any valid DMX512 address number for the
standard input A (DMX A), input B (DMX B) or network.
Circuit ID—used by SWC and status reporting software.
Record and recall presets (1-8, ON and OFF per room for Outlook control, and
0-128 per rack for System Wide Control).
Define Preset Number or “Hold” condition on DMX failure.
Define power-up preset per rack for Outlook architectural presets.
Set LCD contrast.
Error log accessible from the processor module or status reporting software.
Individual dimmer reporting enable/disable.
Dimmer Configuration
Configuration items associated with the dimmer module can be set from the
processor module front panel.
The output response profile can be set to Linear, Square, S-Curve, FluoElectric (for electronic fluorescent ballasts), Fluo-Magnetic (for magnetic
fluorescent ballasts), and Non-Dim. The two fluorescent settings let you set
the top end voltage and the bottom end cutoff voltage. The Non-Dim setting
lets you set the turn-on threshold for the non-dim. Five additional user
programmable profiles are available through the Set Rack Configuration menu
or from the optional status reporting software.
Dimmer response (per dimmer): fast (30ms), normal (100ms) or slow (300ms).
This determines a dimmer’s rate of response to a change in control level. Slow
is usually set for large tungsten loads to reduce filament inrush, medium or
fast for small loads.
Dimmer control assignment (per dimmer) to the “combined” levels of Outlook
preset, SWC preset, DMX A, DMX B, Network or to a fixed level (0% - 99% or
“Full”). The way in which the various input levels combine is also determined
on a per dimmer basis by setting the dimmer DMX mode.
A special smoothing algorithm is applied to small level changes to maintain
smooth fades with long fade times.
Control Inputs The Control Interconnection Card, or CIC, is the printed circuit board on which all
contractor control wiring connections are made. It is located on the top of the Rack
Processor Housing (RPH) and contains:
Operations Manual
Page 16
An optional Ethernet switch, which connects to a Strand ShowNet system and
is Advanced Network Control (ACN) ready. This switch allows for easy
connections between dimmer racks. It also connects to the network
receptacle located in the upper left rear of the dimmer rack.
Two optically isolated DMX512 control inputs. The first input will accept
DMX512. The second DMX512 input is configurable to accept either
DMX512, Strand Lighting’s System Wide Control (SWC) dimmer protocol or

Set Full Output Volts Allows you to set the Maximum output voltage for any range of dimmers in the
rack. For instance, you can set the maximum voltage lower than the rated voltage
of your lamps for improved lamp life. If you have lamps or other equipment which
operate at a lower line voltage, you can set the output from the mdimmer to an
appropriate voltage for the devices.
The maximum output voltage is applied to all dimmers and dimmers assigned as
non-dims. It is not applied to contactor non-dims. You cannot use contactor nondims for devices which need a maximum output voltage setting.
Note: This function sets the dimmer output voltage, not the maximum
control level applied to the dimmer.
Caution: Be careful when using a maximum output voltage with dimmers set for
PANIC. When panic is activated, full output voltage appears at the output of any
dimmer or non-dim set for PANIC, regardless of how the maximum output voltage
is set.

Set Response Times The response time of a dimmer is the rate at which it responds to increases or
decreases in the control level. C21/EC21 dimmer racks provide three response
times:
Slow = 300ms
Medium = 100ms
Fast = 30ms
These options can be applied to a single dimmer or a range of dimmers. Slow is
generally used for large lamp loads, while fast is used for smaller lamp loads that
might be used in a chase effect.
Note: The ‘fast’ setting, together with the accuracy of digital dimmers can cause
very high inrush currents to flow. These may damage large lamp filaments and
cause circuit breakers to trip. Only set dimmers to ‘fast’ if necessary for a
particular effect. Do not use ‘fast’ for lamps that are 5Kw or higher.

Messages are sent from an A/V controller at a maximum rate of 2 Hz
(2 messages per second).
UART Configuration:
9600 Baud, 8 data bits, No Parity, 1 stop bit
Message Overview:
Messages are composed of a short string of printing ASCII characters that request
certain actions from the rack processor. Messages are acknowledged by the
processor with confirming reply messages or with status update messages.
Messages are transmitted as byte streams terminated by designated printing ASCII
characters. There is no requirement for line termination. Received characters that
do not have a defined function in the protocol are ignored.
Operations Manual
Page 38
Message Composition:
Messages are composed of a single command character, followed by an optional
numeric field that may be up to 3 characters long, followed by a single terminating
character. Thus, complete messages range from 2 to 5 characters long.
Command
1 byte
Parameter
0 to 3 bytes
Terminator
1 byte
For all messages received from the AV controller, the terminating character is the
letter ’Z’ in either upper or lower case (0x5A or 0x7A).
For all messages transmitted from the C21 Rack Processor, the terminating
character is the letter ‘Y’ (0x59).
The following messages are defined:
Play SWC Preset:
Command Code: ‘S’ or ‘s’ (0x53 or 0x73)
Parameter:
Up to three digits indicating an SWC preset number in the range
0..128. ‘0’ represents the “Off” preset.
Action:
The rack processor plays back the indicated SWC preset, and responds to the AV
controller with the identical message terminated with the ‘Y’ character instead of
‘Z’. If the preset number was out of range, the response message contains ”???”
instead of the preset requested.
Record SWC Preset:
Command Code:
‘R’ or ‘r’ (0x52 or 0x72)
Parameter:
Up to three digits indicating an SWC preset number in the range 1..128. ‘0’
represents the “Off” preset so is not allowed with this command.
Action:
The rack processor records the indicated SWC preset, and responds to the AV
controller with the identical message terminated with the ‘Y’ character instead of
‘Z’. If the preset number was out of range, the response message contains “???”
instead of the preset requested.
Play Outlook Preset:
Command Code:
‘O’ or ‘o’ (0x4F or 0x6F)
Parameter:
Up to three digits that represent two numeric fields. The first one or two digits
represent the room number. The last digit represents the preset number. The
room number may range from 0..15. The preset number may range from 0..9.
Preset 9 calls the “Full On” preset.
Action:
The rack processor plays back the indicated Outlook preset in the indicated room
Page 39
C21/EC21 Series Dimmer Rack
and responds to the AV controller with the identical message terminated with ‘Y’
instead of ‘Z’. If the room number was out of range, the response message
contains “???” in place of the numeric parameter.
Record Outlook Preset:
Command Code:
‘P’ or ‘p’ (0x50 or 0x70)
Parameter:
Up to three digits that represent two numeric fields. The first one or two digits
represent the room number. The last digit represents the preset number. The
room number may range from 0..15. The preset number may range from 1..8.
Presets 0 and 9 are not allowed as these are not recordable.
Action:
The rack processor records the indicated Outlook preset in the indicated room and
responds to the AV controller with the identical message terminated with ‘Y’
instead of ‘Z’. If the room number or preset number was out of range, the
response message contains “???” in place of the numeric parameter.
Update System Status:
Command Code:
‘U’ or ‘u’ (0x55 or 0x75)
Parameter:
None
Action:
The rack processor responds by sending 17 response messages as defined above
indicating the states of the SWC system and of each room in the Outlook system.

Section 4 - Basic Troubleshooting
General
This section provides basic troubleshooting procedures for C21/EC21 series
dimmer racks. It does not provide comprehensive maintenance data, but lets you
solve simple problems and helps Strand Lighting with initial data when these
procedures are not effective.
For best system operation, do a routine check and cleaning once per year unless
the operating environment is unusually harsh or dirty. Please consult Strand
Lighting Field Service if you are in doubt about the frequency of maintenance
required for your system. Service and maintenance operations other than routine
checks and cleaning are seldom required. In case of problems, and in order to
save time, follow the procedures outlined in this section before calling Strand
Lighting. Take note of the results of each step, as you will be asked this information
if you call a Strand Lighting service representative. In order to avoid
miscommunication, ensure that the person contacting Strand Lighting is the person
doing the tests. All servicing except dimmer and mechanical components should
be performed by sub-assembly replacement.
