CP Electronics UNLCDHS Programming Manual page 16

When there is a requirement to have an 'Off' 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 'Off value' (in the Advanced Programming section) to a value
greater than zero to achieve this low-lit dimmed level for the 'Off' 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.
Configured 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 off after occupancy.
Configured to absence detection: Press and release switch to turn on. Maintains illuminance (dimming channel only). Press
and release switch to turn off. Press and hold switch to dim up and down (reverses direction with each press). Turns off after
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
luminaire on/off and
therefore the 240V feed
to the luminaire fitting
must come from the
permanent live supply.
