When there is a requirement to have an ‘O’ state that results in a low-lit level, then use the DSI / DALI lines as dimming
control with an unswitched live feed direct to the ballast. Set the ‘O value’ (in the Advanced Programming section) to a value
greater than zero to achieve this low-lit dimmed level for the ‘O’ state. See the diagram below for wiring details.
Two channel, individual switches
Functions: Switches both channels with occupancy. Maintains illuminance, dims and switches the dimming channel using
optional single position retractive switch (switch 2). Switches the switching channel using the optional single position
retractive switch (switch 1). For example Legrand Synergy 735415 grid switch or MK K4885 or similar.
Congured to presence detection: Turns on automatically with occupancy. Maintains illuminance (dimming channel only).
Press and release switch to toggle output. Press and hold switch to dim up and down (reverses direction with each press).
Turns o aer occupancy.
Congured to absence detection: Press and release switch to turn on. Maintains illuminance (dimming channel only). Press
and release switch to turn o. Press and hold switch to dim up and down (reverses direction with each press). Turns o aer
occupancy.
Channel mode: Set to “Switch and dim separate”
Switch mode: Set to “1 position switch separate”

Please note that the
dimming signal is used
to switch the diming

therefore the 240V feed

must come from the
