Function test
9 Function test
The function test is only activated
if the motion detector has already
been added.
Up to 10 minutes after pairing or after
switching on the power supply (if the
device has already been paired), the
main lens signals detected movements
in the colour corresponding to the de-
tection zone.
The lens flashes in colour each time a
movement is detected. This allows the
detection range and sensitivity to be
checked directly at the sensor

10 Troubleshooting
10.1 Command not confirmed
If at least one receiver does not con-
firm a command, the device LED (C)
lights up red at the end of the failed
transmission process. The reason for
the failed transmission may be radio in-
terference
(see „13 General information
about radio operation" on page
This may be caused by the following:
• Receiver cannot be reached.
• Receiver is unable to execute the
command (load failure, mechanical
blockade, etc.).
• Receiver is faulty.
10.2 Duty cycle
The duty cycle is a legally regulated
limit of the transmission time of de-
vices in the 868 MHz range. The aim
of this regulation is to safeguard the
operation of all devices working in the
868 MHz range.
In the 868 MHz frequency range we
use, the maximum transmission time of
any device is 1% of an hour (i.e. 36 sec-
onds in an hour). Devices must cease
transmission when they reach the 1%
limit until this time restriction comes to
an end. Homematic IP devices are de-
signed and produced with 100% con-
(see „10.3
formity to this regulation.
During normal operation, the duty
cycle is not usually reached. However,
repeated and radio-intensive pairing
processes mean that it may be reached
in isolated instances during start-up
or initial installation of a system. If the
duty cycle is exceeded, this is indicated
by one long red flash of the device LED
(C), and may be reflected in the device
temporarily working incorrectly. The
device starts working correctly again
after a short period (max. 1 hour).
