  • Dimmer Settings for Use with Source 4WRD


    For assistance changing any dimmer settings, please feel free to call Technical Support.

    For DMX Mode:

    Set dimmer to a switched state or use a relay when controlling Source 4wrd in DMX mode.

    For Line Dimming:

    ControlSmoothing

    All of these settings are available in the [Setup] menu on the CEM3 itself under [Dimmers].

    The SCR Off Time may need to be increased from the default setting. Please contact ETC technical support for assistance in changing the SCR Off Time if necessary.

    CEM+ with D20 or ELV10

    All settings for CEM+ can be accessed when logged in as a POWER USER via the user interface. Code is [3][3][3][3].

    ParameterValue

    In CEM+ it is very important that Max Scale be set to 140V. If this is not set then Regulation will never be truly disabled.

    The SCR Off Time may need to be increased from the default setting. Please contact ETC technical support for assistance in changing the SCR Off Time if necessary.

    Min Scale 13V
    Threshold0%
    Dynamic Preheat 0 seconds
    Transformer Mode On

    Unison DRd with ELV10

    ParameterValue

    ModeLED Smoothing Fwd
    Min Scale 15V
    Threshold0%
    Dynamic Preheat 0 seconds
    Transformer Mode On

    Unison Legacy DR with D20

    Dimming with Unison Legacy DR racks is not ideal. Below 6% the unit will misfire (jump from full to off and back), but above should dim smoothly. Unfortunately there is no way in the older software to set a minimum threshold and avoid the poor dimming below 6%.

    We do not recommend using Source 4wrd with Unison Legacy DR dimming.

    We do not recommend using Source 4wrd with a Dimmer Doubler.

    Smartbars and Smartpacks:

    Smartbars and packs do not have many settings that can be changed. The good news is that they run unregulated at all times. This means that S4wrd can function on these dimmers. They may appear steppy at some points of the fade, but they will dim.

    REPORTING DIMMER SETTINGS FOR NON-ETC DIMMERS

    If you are using S4wrd with another manufacturers dimmers, and have found settings that work for you, please let us know so we can share that information with other users.  To report the proper settings, please e-mail the rack and dimmer information and settings to service@etcconnect.com.
