Control

Luminaires with pin assignment
ƒ
Type C can be controlled by an
inverted signal of the pulse width
modulation (PWM).
Luminaires with pin assignment
ƒ
Type E can be switched on or off digi-
tally in specific colours or in white.
6.1

Digital switching signals

NOTICE
Material damage caused by wrong
mains voltage.
Damage or destruction of the luminaire.
X Operate the luminaire at safety
extra low voltage (SELV) only.
0 signal
Input voltage range: −3 V ... 5 V
X To generate a 0 signal, apply an input
voltage between −3 V and 5 V to the
digital inputs pin no. 2, pin no. 4 or pin
no. 5, see Tab. 5 or see Tab. 6.
1 signal
Input voltage range: 15 V ... 30 V
X To generate a 1 signal, apply an input
voltage between 15 V and 30 V to the
digital inputs pin no. 2, pin no. 4 or pin
no. 5, see Tab. 5 or see Tab. 6.

Powerless switching

Precondition: The luminaire is equipped
with a plug with the pin assignment Type C.
NOTE: Switching cycles may not be smaller
than 0.5 seconds.
Switching on
X Apply a 0 signal to pin no. 4, see Tab. 5.
or
X Do not apply any voltage to pin no. 4.
Switching off
X Apply a 1 signal to pin no. 4, see Tab. 5.

Analog dimming

Precondition: The luminaire is equipped
with a plug with the pin assignment Type C.
A PWM signal is applied to pin no. 4 for
analog dimming. The brightness is regulated
using the duty cycle of the PWM signal.
NOTES:
Dimming is possible between 30 %
ƒ
and 100 % of the maximum bright-
ness.
For dimming, a constant frequency of
ƒ
the PWM signal between 100 Hz and
500 Hz must be available.
The duty cycle is calculated according
ƒ
to the following formula:
Duty cycle [%] = 100 % − bright-
ness [%]
X Set the required frequency.
X Set the required duty cycle.
Example:
To obtain 70 % of the maximum brightness,
a 0 signal must be active at pin no. 4 during
70 % of the PWM signal's oscillation period
and a 1 signal must be active at pin no. 4
during 30 % of the PWM signal's oscilla-
tion period, see Tab. 5. This corresponds to
a duty cycle of 30 %.
