10. Wiring Diagrams

6.1 Single channel dimming
Functions: Switches the luminaire with occupancy and maintains illuminance. Dims and switches using
optional centre biased retractive switch (MK K4900 or similar).
Configured to presence detection: Turns on automatically with occupancy. Maintains illuminance.
Press and release down switch to turn off. Press and release up switch to turn back on. Press and hold up
switch to dim up, press and hold down switch to dim down. Turns off after occupancy.
Configured to absence detection: Press and release up switch to turn on. Maintains illuminance. Press

(IF REQUIRED)
When there is a requirement to have an ‗Off' state that requires a permanent dimmed level. Then use the
DSI / DALI ―pair‖ to both switch and dim, and a live feed direct to the ballast. Set the ‗Off value' (section
4.10 in the Programming section) to a value greater than zero to achieve a permanent dimmed level for
the ‗Off' state. See the diagram below for wiring details.
