MODE 4
AC power interruption (Auto ON activated at delivery)
Auto ON (Mode 4 ON): Following an interruption of the mains voltage, the luminaire turns itself on, regard-
less of whether the luminaire was previously switched on or off. If no presence is detected by the movement
sensor, the luminaire turns itself off again at the end of the Afterglow Period.

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.

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):
0000

Alternatively, you can dim the luminaire to your desired brightness by using the switch or by pressing the
button
on the remote control, which is confirmed by a short flashing of the green LED at the sensor. In
the following 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):
0000

MODE 6
LIGHTDIM CONNECT swarm function (optional)
The swarm function LIGHTDIM CONNECT can be retrofitted into our LED sensor luminaires which can be
ordered 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 high energy efficiency whilst ensuring an
adequate ambient brightness and an optimal lighting atmosphere.
