3.8.4 Functional test of luminaires

The dimmable QTi family from OSRAM (DALI and 1…10 V) gives in

the luminaire test (with 10 Ω filaments) the following power per lamp:

1-lamp/2-lamp (T5 and T8): 32 Watts

3-lamp/4-lamp (T5 and T8): 16 Watts

This function is independent of the deployment of the actual lamp.

For special applications/luminaires, the filament detection can be

switched off – details on request.

If the end test of the luminaire is carried out in TouchDIM mode,

note that the lamp must be dimmed to 100 % light before the discon-

nection of the luminaire from the mains supply . Only in this way is

it ensured that the light can also be switched on with the protection

(without control unit) (DALI standard) during installation of the lumi-

naire. If the luminaire was switched off via TouchDIM the luminaire

also remains off after a loss of voltage – the installer could mistakenly

assume a defective ECG in this case.

If the luminaire has mains voltage applied to it for the first time (without

control unit), it must be switched on with 100 % luminous flux (= DALI

factory setting). The changeover of DALI to TouchDIM mode or vice

versa, assumes a mains voltage failure of the ECG (safety interlock).

3.9 Dimming of amalgam lamps

Since the latest generation of OSRAM QTi DALI/DIM units from the

end of 2008,

amalgam lamps (provided with red stamping ink) can

now also be dimmed without restriction.

Features

• Stable dimming operation down to 1 % (CFL 3 %)

• Considerably more light in a wide ambient temperature range

• 90 % luminous flux from 0 °C to +70 °C (temperature-dependent

cut-off)

• Reliable lamp ignition down to -20 °C

• Power boost stabilizes discharges in the “pink-phase"

• No service life reduction of lamp/ECG

lamp/ECG combinations

• T5: HO CONSTANT: 24 W, 39 W, 54 W, 80 W

Dimming range 1…100 %

• CFL: DULUX L CONSTANT 40 W, 55 W, 80 W

Dimming range 1…100 %

• CFL: DULUX T/E IN PLUS 26 W, 32 W, 42 W, 57 W

Dimming range 3…100 %
