4.2.4 Touch DIM operation
— Switch lamp on/off: Briefl y press push-button (< 0.5 s).
— Dimming: Press and hold push-button (> 0.5 s, dimming
direction changes with every press of the push-button).
— Store the reference value when switched on: “Double-
click” (briefl y press 2 x within 0.4 s).
— Delete reference value: Double-click when lamp is
switched off (ECG starts with 10 % luminous fl ux when
restarting).
Note
Holding the button longer when the lamp is switched off:
The lamp switches on at the minimum dimmer setting and
reduces amount dimmed until the push-button is released.
4.2.5 Operating modes with Touch DIM
With QTi DALI/DIM, OSRAM offers two operating modes
for Touch DIM (mode 1, mode 2), which differ in how they
switch on (switching on/off with the push-button is meant
here, not disconnection of the supply voltage):
Mode 1:
The control gear switches on with the dimming value that
was set before it was switched off. The following applies:
press briefl y: switch, press and hold: dim/switch on at a
minimum dimmer setting.
Mode 2:
The control gear switches on with the dimming value that
was saved previously by double-click (preset value). The
following applies: Press briefl y: switch, press and hold: dim/
switch on at a minimum dimmer setting.
The following table illustrates the options of both operating
modes for the user:
4.2.6 Asynchronism
As a matter of principle, asynchronisms can occur with
push-button operation in systems with more than one ECG.
The higher the number of ECGs and the longer the control
line length, the greater the chance of asynchronisms.
In order to avoid lighting installations running asynchro-
nously in practice, the permissible number of ECGs
(20) and the total line length of 25 m must be adhered
to.
4.2.7 Synchronization
For physical reasons, a Touch DIM system can work asyn-
chronously; in other words, the switching state and dimming
direction of the individual luminaires are different. The follow-
ing steps are used to synchronize a Touch DIM system:
1. Step:
Press and hold (> 0,5 s)
➔ All luminaires switch on
2. Step:
Press briefl y (< 0,5 s)
➔ All luminaires switch off
3. Step:
Press and hold (> 0,5 s)
➔ All luminaires switch on and dim
4. Step:
Double-click
➔ Saves dimmer setting (if desired)
Behavior of the ECG after various push-button
actions, TDI = Touch DIM interface
Action Touch DIM
Press briefl y (state:
switched off)
TDI mode I: Switches on with last value before
shutting down
TDI mode II: Switches on with last double-click
value
Press briefl y (state:
switched on)
Switches off and saves value in TDI mode I for
next switch-on
Press and hold (state:
switched off)
Switches on and from minimum, dims up as
long as the push-button is pressed
Press and hold (state:
switched on)
Dims up and down (depending on pending
toggle function or logic function)
Double-click (state:
switched off)
Changing to TDI mode I (= auto memory of the
switch-on value)
Confi rmation: Switching on and dimming to
maximum brightness
Double-click (state:
switched on and
dimming in the
last 30 s)
Changing to TDI mode II (switch-on value =
double-click value)
Confi rmation: Flashes and dims to double-
click value
Double-click (state:
switched on and
no dimming
in the last 30 s)
Holiday switching; only in combination with
LMS sensors (see LMS documents)
