AMX Lighting - Enclosure Worksheet Guide

Curve

:    Curves are used to adjust the performance of the dimming control. The standard 

dimming curve is #1 and the switching curve is an 'N'. Some modules require a specific curve. 
This cell allows the designer to specify a particular curve applied to a dimmer. Control cards/
Accessories are not assigned curves. Assigning curves to unused dimmers is optional. 

CURVE

uses a drop-down menu containing the dimming choices listed below:  

There are some curve choices available within an AMX Lighting Enclosure Worksheet:

Type

:    Use this cell to specify the type of load or fixture the dimmer or switch will control. 

The type of load will often determine the curve chosen, also. This is useful as a reminder 
because certain types of lighting loads require a de-rating or reduction in the amount of Watts 
they can attach to a dimmer. For example, a low-voltage transformer might use curve 6 instead 
of curve 1, and its maximum load in Watts might be reduced from 2400W to 1920W. If the 
type of load is unknown, you can leave this cell blank. Ballasts that dim using a Hot and 
Neutral wires are called 'Two-wire Fluorescent'. Ballasts that dim using a Hot, Dimmed Hot, 
and Neutral wire are called '3-wire fluorescent' and are made popular by the manufacturer 
Lutron. Ballasts that dim using Hot and Neutral wires, along with two low-voltage control 
wires are called '4-wire fluorescent' and are made popular by the manufacturer Advance 
Transformer using the Mark VII ballast.

• Incandescent Loads Use Curve 1

• Curve 2 is used on incandescents to save energy. It reduced levels by 10%

• Curve 3 is used with an Advance Mark VII ballasts

• Curve 5 is used for some 4-wire ballasts

• Curve 6 is designed for low-voltage loads

• Curve 7 is useful for 4-wire ballasts: the RDM-DC series

• Curve 8 is for Lutron FDB ballast; the RDM-FDB series

• Curve N is for non-dim and switched loads. All switch modules should use 

Curve N. Dimmers set for Curve N will not dim: they will only turn On/Off
