Application hints for

OSRAM Touch DIM function

With Touch Dim, OSRAM DALI ECG can be used as convenient dimmers with a memory function by connection of a normal

push button. Touch Dim is no part of the DALI standard but an additional function offered by OSRAM DALI control gears:

- Electronic Control Gear for fluorescent lamps: QTi DALI … DIM

- Low voltage halogen transformer: HTi DALI 150/220-240 DIM

- LED dimmer: OTi DALI DIM

Important !!!

DALI and Touch DIM must never be used at the same time! In other words, control is achieved either with DALI controller or

with the Touch DIM function.

Wiring instructions and compensation:

Fig.: Up to 4 ECGs can be controlled via Push Button Usage. The number of Push Buttons is limited by the sum of the

overall cable length between switch(es) and the connected ECGs which may not exceed 25m.

Switches with glow lamp must not be used. For a cable length of more than 25 m, compensation must be provided for the line

capacitance by connecting a transformer with the following features: primary side 230 V / secondary side 12 V, required power

of transformer: 25 mW per connected ECG (e.g. 100 mW for 4 ECG, 250 mW for 10 ECG a.s.o.) .

either: or:

Option A

: Transformer located close to the ECG Option B: Transformer located close to the push

(e.g. inside the luminaire) button (e.g. inside a recessed flush-device box)
