Auto OFF (Mode 4 OFF): Following an interruption of the mains voltage, the luminaire does not switch itself
on, only when the Movement Sensor is active (Mode 2 ON) and movement is detected.
AC power interruption Auto OFF:
MODE 5
Stored Light Value (deactivated at delivery)
With Constant Light regulator activated (Mode 3 ON) the photocells at the sensor permanently react to the
ambient brightness and regulate the brightness level of the luminaire accordingly.
Should the luminaire be dimmed too much or too little at the preset value, the value must be adjusted. For
this purpose, you must first enable the Stored Light Value.
Activate Stored Light Value (Mode 5 ON):
Alternatively, you can dim the luminaire to your desired brightness by using the switch or the remote control
by pressing the
button, which is confirmed by a short flashing of the green LED at the sensor. In the fol-
lowing 10 seconds, the luminaire will calibrate to the new value. During this time you may not dim or turn
off the luminaire!
We recommend that after saving the Stored Light Value to again deactivate (OFF Mode 5) in order to pre-
vent accidental overwriting.
Deactivate Stored Light Value (Mode 5 OFF):

LIGHTDIM CONNECT swarm function (optional)
The swarm function LIGHTDIM CONNECT can be retrofitted in our LED sensor luminaires which can be orde-
red under the article numbers PD51-3 or PD51-0.
LIGHTDIM CONNECT enables several TOBIAS GRAU LED luminaires with built-in sensors to communicate
simply and efficiently with one another.
With LIGHTDIM CONNECT the luminaires can be operated with energy-efficiency while ensuring an adequate
ambient brightness and an optimal lighting atmosphere.
Afterglow Period
(Set to 15 mins/900 seconds at delivery)
The Afterglow Period is the time between the last movement detected and the luminaire switching itself off..
The Afterglow Period can be chosen as desired from one minute to 30 minutes with the Movement Sensor
activated (Mode 2 ON). Experience shows that our factory setting of 900 seconds is optimal for a normal
use of space. We do not recommend using a value less than 300 seconds as this can cause the luminaire to
malfunction.
