Appendix A: AMX Lighting Curves

RE-DM4 and RE-DM6 RADIA Eclipse Dimmer Modules
FIG. 43 shows three different Low End Settings of 5%, 10%, and 20%. Each curve holds its assigned
value until the dimmer level reaches 0. Ramping up from level 0 will turn on the lamps at three different
levels respectively. Low End settings can be used to correct for problems in dimming various lighting
products at low levels. Dimming ranges can be controlled using the low end setting. Curve 1 dimming
range is normally 0 -120 VAC, but with a Low End Setting of 5 the range is reduced to 26 - 120, or a
20% reduction in total dimming range. A Low End Setting of 10% reduces the range from 40 to 120
VAC or 35% reductions while a Low End Setting of 20 on Curve 1 is about a 50% reduction in dimming
range. Small adjustments in a curve can cause significant changes in a dimmer's response.
