Flashing

Precondition: The luminaire is equipped
with a plug with the pin assignment Type C.
CAUTION
Risk of injury caused by strobe effect.
Risk of injury caused by moving objects,
which are perceived either as slow or
non-moving due to the flashes.
X Before touching lit objects, make sure
that the lit objects are at standstill.

C
A PWM signal is applied to pin no. 2 for
flashing. The flashing frequency and flash
duration of the luminaire are regulated by
means of the frequency and duty cycle of
the PWM signal.

remove themselves immediately
from the light source and a physi-
cian must be consulted.
The maximum flashing frequency is
500 Hz (period of oscillation 2 ms).
The minimum flash duration is 300 µs.
The duty cycle is calculated according
to the following formula:
Duty cycle [%] = 100 % − Flash dura-
tion [%]
The flash duration of 30 % leads to a
lighting intensity of 30 %.
