4.2 OSRAM DALI ECG and Touch DIM interface
To be able to make simple light management systems, the
DALI ECGs from OSRAM also have the integrated Touch
DIM Function. This makes it possible to dim and switch
DALI ECGs directly with mains voltage using the DALI con-
trol terminals (Touch DIM interface = TDI). Only one com-
mercial push-button is required; the controller takes over
the ECG.
The transition between both operating modes – Touch
DIM and DALI operation – can only occur after a power
voltage disruption. During operation, switching between the
operating modes is not possible due to an integrated safety
interlock. You can change between the two operating
modes as often as you like. Touch DIM may never be used
at the same time as a DALI control system.
Touch DIM provides all functions of a comfort dimmer:
— Soft start of the lamp (lamp start in the lowest dimmer
setting (1 %, lowest luminous fl ux)
— Press briefl y: On/off
— Press and hold: Dimming
— Memory function (light value memory with double-click)
— All settings remain intact even in the event of power failure
New expanded Touch DIM properties:
— Set the Touch DIM parameters fl exibly with DALI
magic programming device and Wizard software
— Automatic shutdown of the lamp once there is
suffi cient ambient light (controlled with the Touch
DIM light and motion sensor)
— Optimized synchronicity (control of up to 20 ECGs
on one push-button is possible)
4.2.1 Setting Touch DIM Function parameters
With the new generation of OSRAM DALI ECGs (GII), all
Touch DIM parameters (e.g. min./max. level of light, fade-up
and fade-down time etc.) can be freely programmed with a
DALI magic programming device (see DALI magic manual).

Factory settings:
Fade-up time: 0.7 s (TD min.: 1 %, TD max.: 100 %)
Fade-down time: 32 s
Delay time: 15 min
Standby time: 5 s
4.2.2 Automatic lamp switch-off at suffi cient light
level
When using the Touch DIM Function with a light and motion
sensor (LS/PD signal), the level of light can be constantly
maintained at the workplace (ECG readjusts artifi cial light).
The following correlation applies in the process: The more
natural light is available, the less artifi cial light (lamp) is re-
quired to maintain a constant level of light at the workplace.
When using the control limits (lowest dimming level (TD
min.)), DALI GII ECGs offer the possibility of shutting down
artifi cial light (ignoring the PIR sensor signal as long as the
light sensor detects a level of light that is over the selected
setpoint for more than 1 min). If the natural level of light falls
below the setpoint by more than an adjustable threshold
value (factory setting approx. 25 lux), the artifi cial light is
switched on again to ensure a constant level of light at the
workplace.
