Installation
Portable Single Dimmers
Location
Place Portable Single Dimmers in a ventilated area free of excessive humidity or condensation and accessible only to authorized
personnel. Ambient temperature should be between 0° and 40° C (32° and 104° F). Heat sink must be kept clear for proper
ventilation and heat dissipation.
NOTE: Turn the circuit breaker OFF before making any connections to the dimmer.

• Connect the FD3-6KW or FD3-12KW panel mounted power input plug (see Fig. 4) to
a branch circuit protected 120VAC 60Hz power source using a cable that is properly
grounded and appropriately rated. The acceptable input voltage range for this unit is 95-
130VAC.
• Connect the FD3-24KW panel mounted power input plug (see Fig. 4) to a branch circuit
protected 240VAC 60Hz power source using a cable that is properly grounded and
appropriatelyrated.Theacceptableinputvoltagerangeforthisunitis190-240VAC,soa

• Do NOT power any Portable Single Dimmers from a dimmed circuit.
Load
All Portable Single Dimmers can control incandescent and inductive loads including lamps and magnetic transformers in the dim mode.
The dimmers are leading-edge (forward-phasing) and as such it is NOT recommended that are used for speed control of fans or other
motors. Be sure to include transformers in load calculations.
NOTE:
• Care must be taken to assure that non-dimmable loads are only operated in the relay mode.
• The circuit breaker should be switched off before connecting the load.
• Set the control output to zero or a pre-heat level before energizing the load.
• Plugload(s),uptothecapacityofthedimmer,intothepoweroutputreceptacleusingproperlygroundedandappropriatelyrated
cables.
Connecting Control Wiring
• ForcontrolusingDMX512-Adataprotocol,plugcontrolcablesconstructedforthisuseintothe5-pinXLRconnectors(seeFig.2)
labelled “DMX IN” and “DMX OUT” (if cable run continues beyond this unit)
• DMX512-A rules require the use of a plug-in terminator on the last unit in a DMX daisy chain. The termination plug should be
plugged into the “DMX OUT” receptacle.
NOTE:
• FD3 units are not self-terminating.

Set-Up and Operation
• Manual Control: A rotary dial allows the dimmer output to be set from 0% to 100% (0 - 10) at the unit. The dimmer’s output will
be a square-law dimming curve proportional to the rotary dial setting at any moment.
PLEASE NOTE: If the rotary dial is at any level greater than 0% (0) it will override any DMX level.
• Remote Control: The DMX function allows the unit to be operated remotely using the DMX512-A data protocol over a wired or
wireless system.
• Setting the Start Address:
• Using(+)and(-)pushbuttonsattheDMXADDRESSpanel,thestartingaddressmaybesetbetween001and512.
• The address will be displayed and held until changed.
• Wired Remote Control:
• Set CRMX WIRELESS switch to ‘DMX ONLY’.
• Plug control cables constructed for this use into the 5-pin XLR connectors labelled “DMX IN” and “DMX OUT”.
• DMX512-A rules require the use of a plug-in terminator on the last unit in a DMX daisy chain. The termination plug should be
plugged into the “DMX OUT” receptacle.
• A single green LED labelled ‘DMX’ will indicate the presence of a DMX signal
• NOTE: FD3 units are NOT self-terminating.
• Wireless Remote Control:
• Connect antenna to the 5dbi receptacle on control panel face.
• Set CRMX WIRELESS switch to ‘ENABLE’.
• Press the ‘HOLD TO UPLINK’ button and the dimmer will auto-connect to the CRMX/WDMX system.
• ToUNLINKdimmer,press‘HOLDTOUPLINK’buttonforthreeseconds.
• NOTE:
• Dimmer must be unlinked before linking with new transmitter.
• A four-step LED indicator labelled ‘WIRELESS SIGNAL’ will indicate signal strength.
• Status Quo:
• Upon DMX-512A signal loss the dimmer will hold the last level received for up to 30 minutes.
• Set the ‘STATUS QUO’ button to ‘ON’.
• Restoration of DMX512-A signal or raising the rotary dial above the ‘0’ level will place the dimmer back into normal operation.
• Lamp Warmer:
• Dimmer output is set to 5% of line voltage even when the slider is set to ‘0’ or the DMX512-A signal is set to zero.
• Set the ‘LAMP WARMER’ button to ‘ON’
• This function is deactivated when the dimmer is set to NON-DIM.
• Dim/Non-Dim:
• The dimmer will function as a switch on or off.
• Set the ‘NON DIM/DIM’ switch to ‘NON DIM’
• The relay function may be controlled locally by the fader or remotely via DMX512-A.

ȽMake sure the dimmer is in DIM mode (Toggle DIM/NON-DIM selector switch to the DIM position).
Unit does not respond to remote DMX512-A input:
ȽCheck all control cabling and check that DMX LED is illuminated to indicate presence of control signal.
