Curve:
The curve menu allows you to set a dimmer or a range of dimmers to a specific dimmer
curve. A dimmer curve is a mathematical function that maps control levels to RMS output
voltage. Curves are scaled from the minimum voltage to the maximum voltage.
The Paradigm ACP provides two dimmer curves for use including Modified Square Law and
Linear. See “Dimmer Module Defaults” on page 86.
Step 5: Scroll to “Curve” and press enter ( ). Selectable dimmer curves will display.
Step 6: Scroll the list and press enter ( ) to select a new dimmer curve.
Threshold:
Threshold allows you to set a dimmer or a range of dimmers to a specific threshold control
level (0-100%) at which it begins to respond. Below that threshold level, the dimmer
remains off. The default value is 0%.
Step 7: Scroll to “Threshold” and press enter ( ). The focus changes to the value field.
Step 8: Use the touch wheel to scroll to the desired value or use the alpha-numeric
button pad to enter the desired value (0-100%). Press enter (
) to accept the
selection.
Voltage Reg:
Voltage Regulation is an On or Off setting. When enabled, the dimmer or range of dimmers
will regulate to the desired output voltage as determined by Maximum Scale settings. When
disabled, the selected dimmers will be set to a constant firing time based on the control
level. When voltage regulation is disabled, Max Scale voltage is not displayed for
configuration.
Step 9: Scroll to “Voltage Reg:” and press enter ( ). The voltage regulation menu
displays.
Step 10: Use the touch wheel to scroll to the desired On or Off value. Press enter ( ) to
accept the selection.
Minimum Scale:
Minimum scale allows you to set a dimmer or a range of dimmers to a minimum output
voltage, which is the bottom of the scaled output of the dimmer(s). The dimmer will switch
on to an RMS output voltage of minimum scale voltage when the control level reaches the
value set for threshold.
•
120 VAC systems default is 6V (adjustable range 1-140)
• 240 VAC systems default is 12V (adjustable range 1-280)
• 277 VAC systems default is 12V (adjustable range 1-300)
Step 11: Scroll to “Min Scale:” and press enter ( ). The voltage regulation menu
displays.
Step 12: Use the touch wheel to scroll to the desired value. Press enter ( ) to accept the
selection.
N o t e : LightDesigner provides an advanced feature that can be used when a connected
dimming system does not support its own curves. This is referred to as “Output
Curves” in Light Designer and normally isn’t used with an ETC dimming system.
ETC recommends using the “Dimmer Setup” menu found in the Paradigm ACP for
configuring the DRd enclosure, applying the appropriate curve for the selected
module type.
Applying curves from both the Paradigm ACP “Dimming Setup” menu and an
“Output Curve” from LightDesigner can yield unexpected dimming results.
