SMD810 Instruction Manual - W4386A
AUX Input - This is a dry contact interface that is active low. The dry contact is connected between the AUX and
GND terminals on the SceneSelect bus connector strip. The function of the AUX input is programmable.
Ensure that the cable length between the dry contact and terminal strip is no longer than 2 metres.
Service LED - The Service LED has 3 signalling modes, which are useful for troubleshooting:
Blinking slowly (1Hz) = Normal Operation
Blinking fast (0.25Hz) = Network Activity Detected
On = Fault
Service Switch - The Service Switch has three functions:
1 push = Transmit Network ID
3 pushes = All Channels 100%
Push & hold for 4 sec = Reboot

Incandescent lamps are easily dimmed using all SceneSelect II dimmers. The
soft start and voltage limiting features will extend lamp life. Lamp life can be
further extended using the voltage limit adjustment.
Tungsten halogen and other transformer loads are easily dimmed using all
SceneSelect II dimmers. The soft start, cleanup and surge limiting features will
protect lamps against premature failure. Lamp life can be extended using the
voltage limit adjustment.
Can be dimmed to as low as 1% using a dimmable electronic ballast.
No de-rating is necessary with electronic ballasts. 1-10V, DSI and DALI
ballasts can be controlled.
Some types of 4 pin PL lamps can be successfully dimmed using dimmable
electronic ballasts.
Only argon filled neon lamps can be reliably dimmed. The power factor
capacitors need to be wired to the supply side of the dimmer. Cabling and
controllers should be de-rated by approx 60% to allow for reactive current. Any
open circuit monitoring on the neon transformer must be suitable for dimming.
