Wiring diagrams

Channel 1 (switched output) of the EBDHS-DD-LT30 can
either be used to switch a separate channel of standard,
non-dimming luminaires, or to isolate the mains supply to
dimming ballasts (saving on the standby current of the
ballasts).
Multiple luminaires may be connected in parallel to
Channel 1 (via the N and L/Out terminals) as long as the
maximum total load is not exceeded.
Channel 2 (dimmable output) of the EBDHS-DD-LT30 can
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 and release
down switch to turn off. Press and hold up switch to dim up, press and hold down switch to dim down. Turns off after
occupancy.
Channel mode: Set to "Switch and dim together".
Switch mode: Set to "2 position switch together".

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' (in the Advanced 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.

be used to control the light output of luminaires that are
fitted with dimming ballasts/transformers.
The ballasts/transformers can be connected in parallel to
Channel 2 (via the DIM– and DIM+ terminals). Refer to the
specification on page 12 for ballast quantities.
The wiring examples below show common methods of
connecting the output channels for a single detector unit.
