Sensor dimmer settings
The Source 4WRD can be controlled from either a DMX source or from an
existing dimmer for level control.
When powering a fixture from a CEM classic, CEM+, or CEM3 for DMX
dimming or AC level setting, change max scale settings to guarantee the
dimmer is out of regulated mode.
The following table applies to all ETC Sensor control modules including CEM,
CEM+, and CEM3.
The SCR Off Time may need to be increased from the default setting. Contact
ETC for assistance in changing the SCR off time, or any other CEM classic,
CEM+, or CEM3 settings.
For the most current information on additional dimmer performance testing
for both ETC and non-ETC dimmers, please reference our website at:
etcconnect.com/Support/Articles/Dimmer-Settings-for-Use-with-Source-
4wrd.aspx.
Note:
Dimmer settings may need to be adjusted for optimal
fixture control.
Note:
In CEM+ Max Scale must be set to 140V to guarantee that
regulation is off.
Parameter Value Parameter Value
Curve Mod Square Preheat Disabled
Threshold 1% DC Prevent OFF
Min Scale 6V Inrush Protect OFF
Max Scale 140V Scale Load 100
Regulation OFF
Note:
With AC dimming (line-dimmed) mode, performance
may vary based on the control settings of the dimmer
used. For this reason, ETC recommends using AC dimming
for level-setting or for architectural quality dimming
situations. ETC recommends testing Source 4wrd on all
existing dimmers you wish to use.
Use DMX mode when high-performance, live, dynamic
dimming is required.
