D20SW Dimmer Module Default Properties
* ETC sine wave dimming produces no DC component so this function
is unnecessary. Checking this may reduce the dimmer’s response time
by up to 8.3 msec.
** This feature is automatically in effect regardless of the setting
because of the nature of ETC’s sine wave dimming.
SineWave Differences You Need to Know
The SineWave rack (SW24+) and module (D20SW) are very similar in most operational
respects to SR racks and D20AF dimmers. However, there are a few notable differences
listed here:
• D20SW dimmers have built-in electronic overcurrent protection and it is unlikely that
you will ever see a breaker trip on a dimmer module. When an overcurrent event occurs
the dimmer will shut itself off and the red overcurrent LED will come on.
To reset the dimmer, bring the level of the dimmer to zero (0) for a minimum of 1 second
and the dimmer will reset itself and begin to operate again.
• The power LED on D20SW’s is blue instead of red as on other D20-family modules.
• The green signal LED on the D20SW module will not come on if the dimmer’s breaker
is turned off. On other D20-family modules, the green signal LED will continue to show
the presence of level for the dimmer even if the dimmer breaker is turned off.
• If you pull the CEM+ out of a SineWave rack, the D20SW dimmers will remain on at the
last level they had for 3 seconds and then fade out. This is a function of the dimmers
losing communication with the CEM+.
