9.1 DALI part
9.1.1 Touch DIM and Corridor Function
— Where are the Touch DIM and Corridor Functions
found?
Directly after switching on the ECG power supply: Acti-
vate the Corridor Function by permanently applying the
supply voltage (220 V–240 V) to the DALI input of the
ECG for at least 120 seconds (50 Hz) and 100 seconds
(60 Hz), respectively. Touch DIM can be accessed by
pressing and holding.
— How do I navigate from the Corridor to the Touch
DIM Function?
Change from the Corridor Function to the Touch DIM
Function by pressing a push-button 5 times (at the DALI
input, 220 V-240 V) within 3 seconds.
Warning: Only individually tapping the push-buttons is
accepted; double-clicks are ignored when changing op-
erating modes.
— May the Touch DIM Function and a DALI control
unit be used simultaneously?
No. Either a DALI control unit or the Touch DIM Function.
Touch DIM and DALI operation cancel each other out.
— How do the ECGs react after a power voltage
disruption?
QTi-series DALI ECGs automatically restart the previous
state. The switching state (on/off) as well as the dimmer
setting should be taken into account here.
— Can devices which are not in sync be
synchronized?
Yes, implement the following sequence:
— Hold the push-button pressed (> 3 s; all ECGs on)
— Briefl y press the push-button (all ECGs are switched
off)
— Hold the push-button pressed (all ECGs switch on in
the lowest dimmer setting and dim up)

— Can several DALI ECGs be attached to a single
push-button?
Up to 20 ECGs can be controlled by a push-button. Up
to 64 DALI ECGs can be operated in the Touch DIM
mode with a single DALI repeater.
— What is the maximum permissible line length
between the push-button and the ECG?
Additional measures must be taken for lines longer than
25 m in order to suppress disruptions (e.g. bell trans-
former).
— Which push-buttons may be used?
Any push-button which is suitable for mains voltage may
be used, however, not push-buttons with glow lamps.
— Does Touch DIM only function with 230 V AC
voltage?
No, Touch DIM is possible from 10 V to 230 V
(effective value!) AC voltage.
— Can I also use DC voltage for Touch DIM?
No, it must be AC voltage with a frequency between
48 and 63 Hz.
— Can a Touch DIM system be upgraded with a
DALI control unit?
Yes, an upgrade is possible at any time. The transition
of the DALI ECGs from Touch DIM to DALI occurs auto-
matically after the power voltage disruption to the ECGs,
when sending the fi rst DALI command.
Touch DIM and DALI are not allowed at the same time!
— Can the motion function of the Touch DIM sensor
be temporarily switched off (vacation switching)?
Yes, so-called vacation switching prevents the motion
sensor switching it on. Activated by double-clicking the
push-button if dimming has not been triggered manually
beforehand within the last 30 seconds. The motion sen-
sor is activated by pressing the push-button.
9.1.2 DALI in general
— Do the ECGs have to be addressed with DALI?
No, it will also work without addressing (broadcast
mode).
— What is the difference between DSI and DALI?
DSI is a company-specifi c solution, not a universal
manufacturer standard like DALI. Digital addressing is
not possible with DSI and, therefore, no free group
formation and no individual query is possible after er-
rors. Groups must be formed through wiring, as in the
1…10-V technology.
— Does the DALI group assignment need to be
observed when wiring?
No, the group is not assigned (addressing) until fi rst
commissioned.
— Does the polarity of the DALI control line need to
be observed?
The polarity does not have to be observed when using
OSRAM DALI control gears.
