Example 1: Single channel switching
Example 2: Single channel dimming
Functionality
Dimmable load control via suitable
ballast/transformer.
Mains power to ballast switched
by channel 1.
Presence or absence detection
(with or without Lux Level control).
Manual scene/level control using
IR Handset or AT-BB-IN Input Unit
and associated switch/button
plate.
Optional Maintained Illuminance
Level control.
Functionality
Simple On/Off load control.
Presence detection.
Absence detection using an AT-
BB-IN Input Unit and associated
switch/button plate.
Manual On/Off control using IR
Handset.
Lux switching.
Channel 1 (switched output) of the EBDSPIR-AT-AD 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 EBDSPIR-AT-AD can
be used to control the light output of luminaires that are
fitted with dimming ballasts/transformers.
Up to 10 ballasts/transformers can be connected in parallel
to Channel 2 (via the
DIM–
and
DIM+
terminals). Ensure
that correct polarity is maintained at each ballast.
The wiring examples below show common methods of
connecting the output channels for a single detector unit.
